In the latter mode the # processor can take an exception when it encounters denormalized # floating-point inputs or outputs rather than dealing with them in # hardware. # # This patch adds code to deal properly with the exception, by emulating # the instruction that caused the exception. Previously the kernel just # switched the altivec unit into the truncate-to-zero mode, which works # but is a bit gross. Fortunately there are only a limited set of altivec # instructions which can generate the assist exception, so we don't have # to emulate the whole altivec instruction set. # # Note that Altivec is Motorola's name for the PowerPC vector/SIMD # instructions; IBM calls the same thing VMX, and currently only IBM makes # 64-bit PowerPC CPU chips. Nevertheless, I have used the term Altivec in # the PPC64 code for consistency with the PPC32 code. # # Signed-off-by: Paul Mackerras # Signed-off-by: Linus Torvalds # # ChangeSet # 2004/06/22 19:52:02-07:00 benh@kernel.crashing.org # [PATCH] radeonfb: Fix panel detection on some laptops # # The code in radeonfb looking for the BIOS image currently uses the BIOS # ROM if any, and falls back to the RAM image if not found. This is # unfortunatly not correct for a bunch of laptops where the real panel # data are only present in the RAM image. # # This works around this problem by preferring the RAM image on mobility # chipsets. This is definitely not the best workaround, we need some arch # support for linking the RAM image to the PCI ID (preferrably by having # the arch snapshot it during boot, isolating us completely from the # details of where this image is in memory).

See File Times. This is used by programs that do backups, so that # backing a file up does not count as reading it. Only the owner of the # file or the superuser may use this bit. # # It is useful if you want to do something with the file atime (for instance, # moving files that have not been accessed in a while to somewhere else, or # something like Debian's popularity-contest) but you also want to read all # files periodically (for instance, tripwire or debsums). # # Currently, the program that reads all files periodically has to use utimes, # which can race with the atime update: # # A B # open # fstat # read # open # read # close # close # utimes # # And the file still has the old atime, instead of the new one from when B # did the read from it. This problem does not happen if A uses O_NOATIME # instead of utimes to preserve the atime. # # This patch adds the O_NOATIME constant for all architectures, but it would # also be possible to add it one architecture at a time by defining it to 0 # when not defined in asm-*. # # Based on patch by Marek Michalkiewicz at # http://www.uwsg.iu.edu/hypermail/linux/kernel/9811.2/0118.html # # Signed-off-by: Andrew Morton # Signed-off-by: Linus Torvalds # # include/linux/fs.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +2 -1 # O_NOATIME support # # include/asm-x86_64/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-v850/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-sparc64/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-sparc/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-sh/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-s390/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-ppc64/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-ppc/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-parisc/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-mips/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-m68k/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-ia64/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-i386/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-h8300/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-cris/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-arm26/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-arm/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # include/asm-alpha/fcntl.h # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +1 -0 # O_NOATIME support # # fs/namei.c # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +5 -0 # O_NOATIME support # # fs/fcntl.c # 2004/06/20 18:20:57-07:00 cesarb@nitnet.com.br +6 -1 # O_NOATIME support # # ChangeSet # 2004/06/20 18:52:59-07:00 dhowells@redhat.com # [PATCH] Permit inode & dentry hash tables to be allocated > MAX_ORDER size # # Here's a patch to allocate memory for big system hash tables with the # bootmem allocator rather than with main page allocator. # # It is needed for three reasons: # # (1) So that the size can be bigger than MAX_ORDER. IBM have done some # testing on their big PPC64 systems (64GB of RAM) with linux-2.4 and found # that they get better performance if the sizes of the inode cache hash, # dentry cache hash, buffer head hash and page cache hash are increased # beyond MAX_ORDER (order 11). # # Now the main allocator can't allocate anything larger than MAX_ORDER, but # the bootmem allocator can. # # In 2.6 it appears that only the inode and dentry hashes remain of those # four, but there are other hash tables that could use this service. # # (2) Changing MAX_ORDER appears to have a number of effects beyond just # limiting the maximum size that can be allocated in one go. # # (3) Should someone want a hash table in which each bucket isn't a power of # two in size, memory will be wasted as the chunk of memory allocated will # be a power of two in size (to hold a power of two number of buckets). # # On the other hand, using the bootmem allocator means the allocation # will only take up sufficient pages to hold it, rather than the next power # of two up. # # Admittedly, this point doesn't apply to the dentry and inode hashes, # but it might to another hash table that might want to use this service. # # # I've coelesced the meat of the inode and dentry allocation routines into # one such routine in mm/page_alloc.c that the the respective initialisation # functions now call before mem_init() is called. # # This routine gets it's approximation of memory size by counting up the # ZONE_NORMAL and ZONE_DMA pages (and ZONE_HIGHMEM if requested) in all the # nodes passed to the main allocator by paging_init() (or wherever the arch # does it). It does not use max_low_pfn as that doesn't seem to be available # on all archs, and it doesn't use num_physpages since that includes highmem # pages not available to the kernel for allocating data structures upon - # which may not be appropriate when calculating hash table size. # # On the off chance that the size of each hash bucket may not be exactly a # power of two, the routine will only allocate as many pages as is necessary # to ensure that the number of buckets is exactly a power of two, rather than # allocating the smallest power-of-two sized chunk of memory that will hold # the same array of buckets. # # The maximum size of any single hash table is given by # MAX_SYS_HASH_TABLE_ORDER, as is now defined in linux/mmzone.h. # # Signed-off-by: Paul Mackerras # Signed-off-by: David Howells # Signed-off-by: Andrew Morton # Signed-off-by: Linus Torvalds # # mm/page_alloc.c # 2004/06/20 18:20:10-07:00 dhowells@redhat.com +73 -0 # Permit inode & dentry hash tables to be allocated > MAX_ORDER size # # init/main.c # 2004/06/20 18:19:55-07:00 dhowells@redhat.com +1 -0 # Permit inode & dentry hash tables to be allocated > MAX_ORDER size # # include/linux/mmzone.h # 2004/06/20 18:19:55-07:00 dhowells@redhat.com +12 -0 # Permit inode & dentry hash tables to be allocated > MAX_ORDER size # # include/linux/kernel.h # 2004/06/20 18:20:10-07:00 dhowells@redhat.com +9 -0 # Permit inode & dentry hash tables to be allocated > MAX_ORDER size # # include/linux/fs.h # 2004/06/20 18:31:00-07:00 dhowells@redhat.com +7 -4 # Permit inode & dentry hash tables to be allocated > MAX_ORDER size # # include/linux/bootmem.h # 2004/06/20 18:19:55-07:00 dhowells@redhat.com +8 -0 # Permit inode & dentry hash tables to be allocated > MAX_ORDER size # # fs/inode.c # 2004/06/20 18:20:10-07:00 dhowells@redhat.com +18 -42 # Permit inode & dentry hash tables to be allocated > MAX_ORDER size # # fs/dcache.c # 2004/06/20 18:20:10-07:00 dhowells@redhat.com +24 -44 # Permit inode & dentry hash tables to be allocated > MAX_ORDER size # # ChangeSet # 2004/06/20 18:52:48-07:00 daniel.ritz@gmx.ch # [PATCH] pcmcia: enable read prefetch on o2micro bridges to fix HDSP # # enable read prefetching on O2micro bridges.

The receive dma remains in a hung state sometimes. The # transmit operations continue to occur, but no receive activity. # # This was reproduced on several ppc64 systems and the fix has been verified # there. The patch has been tested as well on an ia32 system, which did # not experience the hang because it did not have fifo underruns, which is # a preqrequisite for the hang.

# Add a user_struct pointer to the sigqueue structure. Charge sigqueue # allocation and destruction to the user_struct rather than a global pool. This # per user rlimit accounting obsoletes the global queued_signals accouting. # # The patch as charges the sigqueue struct allocation to the queue that it's # pending on (the receiver of the signal). So the owner of the queue is charged # for whoever writes to it (much like quota for a 777 file). # # The patch started out charging the task which allocated the sigqueue struct. # In most cases, these are always the same user (permission for sending a # signal), so those cases are moot. In the cases where it isn't the same user, # it's a privileged user sending a signal to another user. # # It seems wrong to charge the allocation to the privleged user, when the other # user could block receipt as long as it feels.

AFAIK, they are not # Debian nor sparc specific but I'm not subscribed to linux-kernel mailing list # and since I'm involved with boot-floppies (mainly for sparc), I think I'm right # to report it here. Feel free to forward it upstream (I checked the latest # 2.3.46 sources and it seems these bugs are still there). # # These bugs are not release critical. The latter just not gives the user a # chance to overwrite TERM env var at boot time. It could be just # inconvenient for serial console boot, and in this case, our busybox' init is # already enforcing TERM=vt102. # Nevertheless if it could not be fixed before the release, I could even write a # workaround in busybox' init (it's just a matter of rewriting getenv()). # # At last, it does not affect sysvinit package because serial console tty is # controlled by a getty process which is reading terminal settings on its command # line (take a look in inittab for T0 entries, if any). # # Ok, here is my modest contribution to kernel hacking. I don't know much about # kernel internals but it seems that argument parsing is a bit broken. # # One trivial patch for command line like "init=/bin/sh console=prom" where # console=prom is replaced by lot of spaces in previous call to setup_arch() on # sparc, therefore the line parsed by parse_options() is really # "init=/bin/sh " and a lot of null args are pushed into argv_init. # # The other patch is for command line like "TERM=vt100" where both default & user # TERM entries are pushed into the env array. # Taking a look into /proc/1/environ, it shows up: # HOME=/ # TERM=linux # TERM=vt100 # # It appears that ash (maybe other shells too) is giving the latter entry but # glibc getenv() is giving the former. It is therefore impossible to get entry # from the user in a C program like busybox' init (used in Debian boot-floppies). # # I guess getenv() is not written to support duplicate entries, therefore the # kernel should avoid such construct. # # Signed-off-by: Andrew Morton # Signed-off-by: Linus Torvalds # # init/main.c # 2004/06/18 00:06:03-07:00 wli@holomorphy.com +2 -0 # fix duplicate environment variables passed to init # # ChangeSet # 2004/06/18 08:10:43-07:00 wli@holomorphy.com # [PATCH] unregister driver if probing fails in sb_card.c # # * Unregister driver if probing fails in sound/oss/sb_card.c # This fixes Debian BTS #218845. # http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=218845 # # From: Robin Gerard # To: submit@bugs.debian.org # Subject: no sound with kernel-image-2.6.0-test9-1-386 # Message-ID: <20031103004939.GA2071@mauritius> # # I downlaoded the kernel-image-2.6.0-test9-1-386_2.6.0-test9-1_i386.deb # and I installed it successfully.

All the previous trials since the end of last # year used HAS_NWAY which disables the Tx part of the transceiver; using # HAS_NWAY was the way all 3Com Cyclone and Tornado chips worked, as they had # the transceiver integrated. The ATI solution has an external transceiver # and I had to physically see the different chip on the board (the board was # provided by ATI) to finally understand that it needs the HAS_MII # definition... I'm still waiting for some docs from ATI to clarify if this # is the correct way of handling this chip and if there are any differences # w.r.t EEPROM handling, but as it appears to work and was also confirmed by # other testers, I don't want to keep owners of such boards away from their # networks :-) # # The textual identification was a bit hard to decide; it's called # "3c920B-EMB-WNM" in the Windows .INF file that Asus provides for their # boards. As this name was already used for PCI ID 9210, I added the # paranthesis which specifies where this chip is found. # # The Scyld driver defines FEATURE_TORNADO to include HAS_NWAY. This board # would then probably need to not be defined with FEATURE_TORNADO, but the # same as in this patch. # # I would like to publicly thank Tyson Vickers for both ideas and patience # during the last few weeks. He managed to get the driver working by # randomly setting driver parameters :-) But then he contacted me and worked # with me towards the solution. # # Signed-off-by: Andrew Morton # Signed-off-by: Linus Torvalds # # drivers/net/3c59x.c # 2004/06/17 23:53:42-07:00 bogdan.costescu@iwr.uni-heidelberg.de +8 -4 # 3c59x: support for ATI Radeon 9100 IGP # # ChangeSet # 2004/06/18 08:01:58-07:00 thomas@winischhofer.net # [PATCH] sisfb update 1.7.10 # # attached is an update for the sisfb driver to version 1.7.10. # # This update includes # # - fixes for pure 64bit and 32/64bit mixed systems (add ioctl conversion; # fix variable sizes, etc; REQUIRED for current X.org/XFree86 on 64bit # systems, even if pure 64bit), # # - fixes for 301C video bridge, (scales TV output correctly now) # # - fixes for 1600x1200 and 1400x1050 LCD panels, # # - many fixes for 661/741/760 (amongst others, proper LFB support for the # 760 and corrections for SiS' new BIOS data layout; would lead to display # corruption with old driver) # # - add support for many modes for LCD which were unsupported previously, # # - add support for HiVision and YPbPr HDTV # # - "vga=" statement now honoured properly (sisfb will set the same mode as # the kernel did by default) # # - use LCD native resolution mode if no mode is given # # - a major clean up of main driver code, # # - radical removal of duplicate (or nearly duplicate) code, # # - switched to 2.6 module_param macros, # # - enhanced communication with the X driver, # # - added eventual POSTing of SiS300/305 card for non-x86 archs, # # - added ability to relocate the image on the TV screen using a userland # tool, # # - added Documentation/fb/sisfb.txt (why the heck was this missing?!) # # - small fix for SiS DRM driver (match 32/64bit fixes mentioned above) # (cast the data passed to sis_free as u32) # # - make driver re-entrant by avoiding static structures and variables. # # As usual, heavily tested.

It is similar to the last # posting except this one implements the NFS get_parent() method which has # always been missing. # # The original problem I set out to addresses is that the current iso9660 file # system cannot reach inodes located beyond the 4GB barrier. This is caused by # using the inode number as the byte offset of the inode data. Being 32-bits # wide, the inode number is unable to reach inode data that does not reside on # the first 4GB of the file system. # # This causes real problems with "growisofs" # # http://fy.chalmers.se/~appro/linux/DVD+RW/#isofs4gb # # and my pet project "shunt" # # http://www.serice.net/shunt/ # # This patch switches the isofs code from iget() to iget5_locked() which allows # extra data to be passed into isofs_read_inode() so that inode data anywhere on # the disk can be reached. # # The inode number scheme was also changed. Continuing to use the byte offset # would have resulted in non-unique inodes in many common situations, but # because the inode number no longer plays any role in reading the meta-data off # the disk, I was free to set the inode number to some unique characteristic of # the file. I have chosen to use the block offset which is also 32-bits wide. # # Lastly, the pre-patch code uses the default export_operations to handle # accessing the file system through NFS. The problem with this is that the # default NFS operations assume that iget() works which is no longer the case # because of the necessity of switching to iget5_locked(). So, I had to # implement the NFS operations too. As a bonus, I went ahead and implemented # the NFS get_parent() method which has always been missing. # # Signed-off-by: Andrew Morton # Signed-off-by: Linus Torvalds # # fs/isofs/export.c # 2004/06/17 23:53:41-07:00 paul@serice.net +228 -0 # iso9660: fix handling of inodes beyond 4GB # # include/linux/iso_fs_i.h # 2004/06/17 23:53:41-07:00 paul@serice.net +4 -1 # iso9660: fix handling of inodes beyond 4GB # # include/linux/iso_fs.h # 2004/06/18 00:32:20-07:00 paul@serice.net +66 -0 # iso9660: fix handling of inodes beyond 4GB # # fs/isofs/rock.c # 2004/06/17 23:53:41-07:00 paul@serice.net +7 -8 # iso9660: fix handling of inodes beyond 4GB # # fs/isofs/namei.c # 2004/06/17 23:53:41-07:00 paul@serice.net +21 -9 # iso9660: fix handling of inodes beyond 4GB # # fs/isofs/inode.c # 2004/06/18 00:32:20-07:00 paul@serice.net +104 -53 # iso9660: fix handling of inodes beyond 4GB # # fs/isofs/export.c # 2004/06/17 23:53:41-07:00 paul@serice.net +0 -0 # BitKeeper file /home/torvalds/v2.6/linux/fs/isofs/export.c # # fs/isofs/dir.c # 2004/06/18 00:32:20-07:00 paul@serice.net +3 -3 # iso9660: fix handling of inodes beyond 4GB # # fs/isofs/Makefile # 2004/06/17 23:53:41-07:00 paul@serice.net +1 -1 # iso9660: fix handling of inodes beyond 4GB # # ChangeSet # 2004/06/18 08:01:23-07:00 tim@physik3.uni-rostock.de # [PATCH] BSD accounting format rework # # BSD accounting format rework: # # Use all explicit and implicit padding in struct acct to # # - correctly report 32 bit uid/gid, # - correctly report jobs (e.g., daemons) running longer than 497 days, # - increase the precision of ac_etime from 2^-13 to 2^-20 # (i.e., from ~6 hours to ~1 min. after a year) # - store the current AHZ value. # - allow cross-platform processing of the accounting file # (limited for m68k which has a different size struct acct). # - introduce versioning for smooth transition to incompatible formats in # the future. Currently the following version numbers are defined: # 0: old format (until 2.6.7) with 16 bit uid/gid # 1: extended variant (binary compatible to v0 on M68K) # 2: extended variant (binary compatible to v0 on everything except M68K) # 3: a new binary incompatible format (64 bytes) # 4: new binary incompatible format (128 bytes). # layout of its first 64 bytes is the same as for v3. # 5: marks second half of new binary incompatible format (128 bytes) # (layout is not yet defined) # # All this is accomplished without breaking binary compatibility. 32 bit # uid/gid support is compatible with the patch previously floating around and # used e.g. by Red Hat. # # This patch also introduces a config option for a new, binary incompatible # "version 3" format that # # - is uniform across and properly aligned on all platforms # - stores pid and ppid # - uses AHZ==100 on all platforms (allows to report longer times) # # Much of the compatibility glue goes away when v1/v2 support is removed from # the kernel.

As there # is no way to pass the kernel configuration to userspace, with my patch it will # still only support the old v2 format.

You will not be able to find many of the # entries. The problem is that the IDR code uses 5-bit chunks of the # number and the lower portion used by IDR is 24 bits, so you have one bit # that leaks over into the comparisons that should not be there. The # solution is to mask off that bit before doing IDR processing. This # actually causes the POSIX timer code to crash if you create that many # timers. I have included an idr_test.tar.gz file that demonstrates this # with and without the fix, in case you need more evidence :). # # * When the IDR fills up, it returns -1. However, there was no way to # check for this condition. This patch adds the ability to check for the # idr being full and fixes all the users. It also fixes a problem in # fs/super.c where the idr code wasn't checking for -1. # # * There was a race condition creating POSIX timers. The timer was added # to a task struct for another process then the data for the timer was # filled out. The other task could use/destroy time timer as soon as it is # in the task's queue and the lock is released. This moves settup up the # timer data to before the timer is enqueued or (for some data) into the # lock. # # * Change things so that the caller doesn't need to run idr_full() to find # out the reason for an idr_get_new() failure. # # Just return -ENOSPC if the tree was full, or -EAGAIN if the caller needs # to re-run idr_pre_get() and try again. # # Signed-off-by: Andrew Morton # Signed-off-by: Linus Torvalds # # net/sctp/sm_make_chunk.c # 2004/06/17 23:41:37-07:00 minyard@acm.org +15 -10 # Fixes for idr code # # lib/idr.c # 2004/06/18 00:32:26-07:00 minyard@acm.org +37 -8 # Fixes for idr code # # kernel/posix-timers.c # 2004/06/17 23:41:37-07:00 minyard@acm.org +52 -34 # Fixes for idr code # # include/linux/idr.h # 2004/06/18 00:32:26-07:00 minyard@acm.org +7 -1 # Fixes for idr code # # fs/super.c # 2004/06/17 23:41:37-07:00 minyard@acm.org +10 -5 # Fixes for idr code # # fs/proc/generic.c # 2004/06/17 23:41:37-07:00 minyard@acm.org +6 -4 # Fixes for idr code # # ChangeSet # 2004/06/18 07:55:25-07:00 mason@suse.com # [PATCH] reiserfs data logging support # # Add data=journal support for reiserfs # # Signed-off-by: Andrew Morton # Signed-off-by: Linus Torvalds # # include/linux/reiserfs_fs_i.h # 2004/06/17 23:41:37-07:00 mason@suse.com +1 -0 # reiserfs data logging support # # include/linux/reiserfs_fs.h # 2004/06/17 23:41:37-07:00 mason@suse.com +8 -0 # reiserfs data logging support # # fs/reiserfs/tail_conversion.c # 2004/06/17 23:41:37-07:00 mason@suse.com +0 -41 # reiserfs data logging support # # fs/reiserfs/stree.c # 2004/06/17 23:41:37-07:00 mason@suse.com +40 -3 # reiserfs data logging support # # fs/reiserfs/journal.c # 2004/06/17 23:41:37-07:00 mason@suse.com +13 -4 # reiserfs data logging support # # fs/reiserfs/inode.c # 2004/06/17 23:41:37-07:00 mason@suse.com +49 -10 # reiserfs data logging support # # fs/reiserfs/file.c # 2004/06/17 23:41:37-07:00 mason@suse.com +18 -2 # reiserfs data logging support # # ChangeSet # 2004/06/18 07:55:13-07:00 mason@suse.com # [PATCH] reiserfs: btree readahead # # Walking the btree can trigger a number of single block synchronous reads. # This patch does btree readahead during operations that are likely to be long # and sequential.

The problem with bitmap groups is that if you've got a # group of subdirectories their contents will be spread out all over the # disk, leading to lots of seeks during a sequential read. # # This allocator patch uses the packing locality to determine which bitmap # group to allocate from, but when you create a file it looks in the bitmaps # to see how 'full' that packing locality already is. If it hasn't been # heavily used yet, the packing locality is inherited from the parent # directory putting files in new subdirs close to the parent subdir, # otherwise it is the inode number of the parent directory putting new # files far away from the parent subdir. # # The end result is fewer bitmap groups for the same working set. For # example, one test data set created by 20 procs running in parallel has # 6822 subdirs. And with vanilla reiserfs that would mean 6822 # packing localities. This patch turns that into 26 packing localities. # # This makes sequential reads of big directory trees more efficient, but # it also makes the btree more efficient in general. Things end up sorted # better because groups of subdirs end up with similar keys in the btree, # instead of being spread out all over. # # The bitmap grouping code tries to use the start of each bitmap group # for metadata, and offsets the data slightly. The data and metadata # are still close together, but not completely intermixed like they are # in the default allocator. The end result is that leaf nodes tend to be # close to each other, making metadata readahead more effective. # # The old block allocator had the ability to enforce a minimum # allocation size, but did not use it. It now tries to do a pass looking # for larger allocation chunks before falling back to the old behaviour # of taking any blocks it can find. # # The patch changes the defaults to: # # mount -o alloc=skip_busy:dirid_groups:packing_groups # # You can get back the old behaviour with mount -o alloc=skip_busy # # mount -o alloc=dirid_groups will turn on the bitmap groups # mount -o alloc=packing_groups turns on the packing locality reduction code # mount -o alloc=skip_busy:dirid_groups turns on both dirid_groups and # skip_busy # # Finally the patch adds a mount -o alloc=oid_groups, which puts files into # bitmap groups based on a hash of their objectid. This would be used for # databases or other situations where you have a limited number of very # large files. # # This command will tell you how many packing localities are actually in # use: # # debugreiserfs -d /dev/xxx | grep '^|.*SD' | sed 's/^.....//' | awk '{print $1}' | sort -u | wc -l # # Signed-off-by: Andrew Morton # Signed-off-by: Linus Torvalds # # include/linux/reiserfs_fs.h # 2004/06/18 00:32:26-07:00 mason@suse.com +10 -1 # reiserfs: block allocator optimizations # # fs/reiserfs/super.c # 2004/06/17 23:41:36-07:00 mason@suse.com +7 -6 # reiserfs: block allocator optimizations # # fs/reiserfs/inode.c # 2004/06/18 00:32:26-07:00 mason@suse.com +1 -2 # reiserfs: block allocator optimizations # # fs/reiserfs/file.c # 2004/06/18 00:32:26-07:00 mason@suse.com +11 -3 # reiserfs: block allocator optimizations # # fs/reiserfs/bitmap.c # 2004/06/18 00:32:27-07:00 mason@suse.com +234 -55 # reiserfs: block allocator optimizations # # ChangeSet # 2004/06/18 07:54:32-07:00 akpm@osdl.org # [PATCH] ppc64: uninline __pte_free_tlb() # # The pgalloc.h changes broke ppc64: # # In file included from include/asm-generic/tlb.h:18, # from include/asm/tlb.h:24, # from arch/ppc64/mm/hash_utils.c:48: # include/asm/pgalloc.h: In function `__pte_free_tlb': # include/asm/pgalloc.h:110: dereferencing pointer to incomplete type # include/asm/pgalloc.h:111: dereferencing pointer to incomplete type # # Uninlining __pte_free_tlb() fixes that. # # Signed-off-by: Andrew Morton # Signed-off-by: Linus Torvalds # # include/asm-ppc64/pgalloc.h # 2004/06/17 23:41:36-07:00 akpm@osdl.org +1 -27 # ppc64: uninline __pte_free_tlb() # # arch/ppc64/mm/tlb.c # 2004/06/17 23:41:36-07:00 akpm@osdl.org +27 -0 # ppc64: uninline __pte_free_tlb() # # ChangeSet # 2004/06/18 07:54:20-07:00 rmk@arm.linux.org.uk # [PATCH] Clean up asm/pgalloc.h include 3 # # This patch cleans up needless includes of asm/pgalloc.h from the arch/i386/ # subtree.

The feature is # documented and the administrator is advised to handle it with care # # - The new feature is enabled only with a special flag in the registration # string. When this flag is not specified the current behavior of # binfmt_misc is kept # # - This is the only 'right' way for an interpreter to know the correct # AT_SECURE value for the interpreted binary # # # From: Chris Wright # # This patchset looks OK, except for one problem. It installs the fd (which # could've been unreadable) without unsharing the ->files. So someone can use # this to read unreadable yet executable files. Here's a patch which fixes # that up. I added one bit that's commented out because I'm not positive if a # final steal_locks() is needed. # # I did a fair amount of rearranging to simplify the error conditions # relative to the fd_install(), and unshare_files(). # # From: Chris Wright # # I found that the intel patchset (and mine as well) leaked i_writecount on # the original executed file.

Following David Mosberger's advice - we use the binfmt_misc # mechanism for the invocation of the translator whenever the user tries to # exec an IA-32 binary. # # The EL is meant to help in the migration path from IA-32 to IPF. From our # beta customers we learnt that at first stage - they tend to keep their # environment mostly intact, using the legacy IA-32 binaries. # # Such an environment has, naturally, setuid and non-readable binaries. It # will be useless to ask the administrator to change the settings of such an # environment - some of them are very complex, and the administrators are # reluctant to make any changes in a system that already proved itself to be # robust and secure. So, our target with these patches is not to enhance the # support for scripts but rather to allow a translator to be integrated into a # working environment that is not (and should not be) aware to the fact it's # being emulated. # # As I said before - it is practically hopeless to expect an administrator of # such a system to change it so that it will suit the current behavior of # binfmt_misc. But, even if we could do that, # # I'm not sure it would be a good idea - these changes are likely to be less # secure than the suggested patches - # # - In order to execute non-readable binaries the binary will have to be made # readable, which is obviously less secure than allowing only a trusted # translator to read it # # - There will be no way for the translator to calculate the accurate # AT_SECURE value for the translated process. This might end up with the # translated process running in a non-secured mode when it actually needs to # be secured. # # # # # I prepared a patch that solves a couple of problems that interpreters have # when invoked via binfmt_misc. currently - # # 1) such interpreters cannot open non-readable binaries # # 2) the processes will have their credentials and security attributes # calculated according to interpreter permissions and not those of the # original binary # # the proposed patch solves these problems by - # # 1) opening the binary on behalf of the interpreter and passing its fd # instead of the path as argv[1] to the interpreter # # 2) calling prepare_binprm with the file struct of the binary and not the # one of the interpreter # # The new functionality is enabled by adding a special flag to the registration # string. If this flag is not added then old behavior is not changed. # # A preliminary version of this patch was sent to the list on 9/1/2003 with the # title "[PATCH]: non-readable binaries - binfmt_misc 2.6.0-test4". This new # version fixes the concerns that were raised by the patch, except of calling # unshare_files() before allocating a new fd. this is because this feature did # not enter 2.6 yet. # # # Arun Sharma says: # # We were going through an internal review of this patch: # # http://marc.theaimsgroup.com/?l=linux-kernel&m=107424598901720&w=2 # # which is in your tree already. I'm not sure if this line of code got # sufficient review. # # + /* call prepare_binprm before switching to interpreter's file # + * so that all security calculation will be done according to # + * binary and not interpreter */ # + retval = prepare_binprm(bprm); # # The case that concerns me is: unprivileged interpreter and a privileged # binary. One can use binfmt_misc to execute untrusted code (interpreter) with # elevated privileges. One could argue that all binfmt_misc interpreters are # trusted, because only root can register them. But that's a change from the # traditional behavior of binfmt_misc (and binfmt_script). # # # (Update): # # Arun pointed out that calculating the process credentials according to the # binary that needs to be translated is a bit risky, since it requires the # administrator to pay extra attention not to register an interpreter which is # not intended to run with root credentials. # # After discussing this issue with him, I would like to propose a modified # patch: The old patch did 2 things - 1) open the binary for reading and 2) # calculate the credentials according to the binary. # # I removed the riskier part of changing the credentials calculation, so the # revised patch only opens the binary for reading. It also includes few words # of warning in the description of the 'open-binary' feature in # binfmt_misc.txt, and makes the function entry_status print the flags in use. # # As for the 'credentials' part of the patch, I will prepare a separate patch # for it and send it again to the LKML, describe the problem and ask for people # comments. # # # Signed-off-by: Andrew Morton # Signed-off-by: Linus Torvalds # # include/linux/binfmts.h # 2004/06/17 23:41:09-07:00 yoav.zach@intel.com +4 -0 # Handle non-readable binfmt_misc executables # # fs/exec.c # 2004/06/18 00:32:28-07:00 yoav.zach@intel.com +3 -1 # Handle non-readable binfmt_misc executables # # fs/binfmt_misc.c # 2004/06/18 00:32:28-07:00 yoav.zach@intel.com +120 -21 # Handle non-readable binfmt_misc executables # # Documentation/binfmt_misc.txt # 2004/06/18 00:32:28-07:00 yoav.zach@intel.com +19 -4 # Handle non-readable binfmt_misc executables # # ChangeSet # 2004/06/18 07:53:23-07:00 mporter@kernel.crashing.org # [PATCH] Add PPC4xx MAINTAINERS entry, merge CREDITS from 2.4 # # Add myself as the PPC4xx maintainer.

Russell King points out that on some # architectures, with the move from 2.4 mm sweeping to 2.6 rmap, this may be a # serious omission: very frequently referenced pages never re-marked young, and # the worst choices made for unmapping. # # So, replace ptep_test_and_clear_young by ptep_clear_flush_young throughout # rmap.c. Originally I'd imagined making some kind of TLB gather optimization, # but don't see what now: whether worth it rather depends on how common # cross-cpu flushes are, and whether global or not. # # ppc and ppc64 have already found this issue, and worked around it by arranging # TLB flush from their ptep_test_and_clear_young: with the aid of pgtable rmap # pointers. I'm hoping ptep_clear_flush_young will allow ppc and ppc64 to # remove that special code, but won't change them myself. # # It's worth noting that it is Andrea's anon_vma rmap which makes the vma # available for ptep_clear_flush_young in page_referenced_one: anonmm and # pte_chains would both need an additional find_vma for that. # # Signed-off-by: Hugh Dickins # Signed-off-by: Andrew Morton # Signed-off-by: Linus Torvalds # # mm/rmap.c # 2004/06/17 23:41:07-07:00 hugh@veritas.com +3 -3 # mm: flush TLB when clearing young # # ChangeSet # 2004/06/18 13:33:48+01:00 rmk@flint.arm.linux.org.uk # [ARM] Add support code for ARM hardware vector floating point # # This cset adds the code to handle the hardware vector floating point # unit found on some ARM926 and later CPUs.

2004/06/17 21:04:44-07:00 paulus@samba.org # [PATCH] ppc64: Optimize exception/syscall entry/exit # # This rewrites the PPC64 exception entry/exit routines to make them # smaller and faster. # # In particular we no longer save all of the registers for the common # exceptions - system calls, hardware interrupts and decrementer (timer) # interrupts - only the volatile registers. The other registers are saved # and restored (if used) by the C functions we call. This involved # changing the registers we use in early exception processing from r20-r23 # to r9-r12, which ended up changing quite a lot of code in head.S. # Overall this gives us about a 20% reduction in null syscall time. # # Some system calls need all the registers (e.g. fork/clone/vfork and # [rt_]sigsuspend). For these the syscall dispatch code calls a stub that # saves the nonvolatile registers before calling the real handler. # # This also implements the force_successful_syscall_return() thing for # ppc64. # # Signed-off-by: Paul Mackerras # Signed-off-by: Linus Torvalds # # include/asm-ppc64/thread_info.h # 2004/06/16 22:46:06-07:00 paulus@samba.org +2 -2 # ppc64: Optimize exception/syscall entry/exit # # include/asm-ppc64/ptrace.h # 2004/06/16 22:46:06-07:00 paulus@samba.org +12 -0 # ppc64: Optimize exception/syscall entry/exit # # include/asm-ppc64/processor.h # 2004/06/16 22:46:06-07:00 paulus@samba.org +1 -2 # ppc64: Optimize exception/syscall entry/exit # # include/asm-ppc64/ppc_asm.h # 2004/06/16 22:46:06-07:00 paulus@samba.org +3 -5 # ppc64: Optimize exception/syscall entry/exit # # include/asm-ppc64/paca.h # 2004/06/16 22:46:06-07:00 paulus@samba.org +9 -11 # ppc64: Optimize exception/syscall entry/exit # # arch/ppc64/xmon/xmon.c # 2004/06/16 22:46:06-07:00 paulus@samba.org +0 -3 # ppc64: Optimize exception/syscall entry/exit # # arch/ppc64/mm/fault.c # 2004/06/16 23:23:50-07:00 paulus@samba.org +33 -24 # ppc64: Optimize exception/syscall entry/exit # # arch/ppc64/kernel/traps.c # 2004/06/16 22:46:06-07:00 paulus@samba.org +15 -1 # ppc64: Optimize exception/syscall entry/exit # # arch/ppc64/kernel/syscalls.c # 2004/06/16 22:46:06-07:00 paulus@samba.org +14 -0 # ppc64: Optimize exception/syscall entry/exit # # arch/ppc64/kernel/signal32.c # 2004/06/16 22:46:06-07:00 paulus@samba.org +1 -1 # ppc64: Optimize exception/syscall entry/exit # # arch/ppc64/kernel/signal.c # 2004/06/16 22:46:06-07:00 paulus@samba.org +2 -2 # ppc64: Optimize exception/syscall entry/exit # # arch/ppc64/kernel/process.c # 2004/06/16 22:46:06-07:00 paulus@samba.org +5 -1 # ppc64: Optimize exception/syscall entry/exit # # arch/ppc64/kernel/pacaData.c # 2004/06/16 22:46:06-07:00 paulus@samba.org +0 -2 # ppc64: Optimize exception/syscall entry/exit # # arch/ppc64/kernel/misc.S # 2004/06/16 22:46:06-07:00 paulus@samba.org +13 -12 # ppc64: Optimize exception/syscall entry/exit # # arch/ppc64/kernel/head.S # 2004/06/16 22:46:06-07:00 paulus@samba.org +707 -760 # ppc64: Optimize exception/syscall entry/exit # # arch/ppc64/kernel/entry.S # 2004/06/16 22:48:02-07:00 paulus@samba.org +277 -193 # ppc64: Optimize exception/syscall entry/exit # # arch/ppc64/kernel/asm-offsets.c # 2004/06/16 22:46:06-07:00 paulus@samba.org +10 -2 # ppc64: Optimize exception/syscall entry/exit # # ChangeSet # 2004/06/17 21:04:32-07:00 paulus@samba.org # [PATCH] ppc64: Implement CONFIG_PREEMPT # # This implements CONFIG_PREEMPT for ppc64.

It's primarily reproducable via adding delays into # various disconnect and reset processing paths, but has also been # encountered in the field. # # This patch started life as as281b, and was modified by me only to patch # properly against current kernels. # # The main features of the patch are: # # Store the host pointer at the start of the control thread # rather than trying to get it from srb->device; after the host # is removed the SCSI device structure may no longer exist. # # Keep dev_semaphore locked during the entire time the control # thread or reset handlers are using the us_data structure. # # Reorder the items in dissociate_dev() and release_resources() # so that things are released in the opposite order from the way # they were acquired originally. Don't bother to increment and # decrement the usb_device's reference count; it's unnecessary. # # In disconnect(), first set the DISCONNECTING flag so that no # more I/O will take place and no more requests will be accepted. # Next, cut short the current command and wait for it to finish. # Then call scsi_remove_host(). The SCSI core guarantees that # when scsi_remove_host() returns, the host will not be in error # recovery and all outstanding commands will have been cancelled. # # Remove some old useless left-over code that was #if'ed out. # # Use a wait_queue for the 6-second delay during device resets # so that we can be woken up in the middle if a disconnect occurs. # # The key point here is that after scsi_remove_host(), everything is idle as # far as the SCSI midlayer is concerned. But if there was a command in # progress at the time, the midlayer will abort it without telling us or # waiting for it to complete. Hence we have to wait for the control thread # to be idle before we can try to kill it. This should happen quickly, # since all I/O attempted by the thread will fail immediately. # # Signed-off-by: Matthew Dharm # Signed-off-by: Greg Kroah-Hartman # # drivers/usb/storage/usb.h # 2004/06/13 13:09:07-07:00 mdharm-usb@one-eyed-alien.net +3 -2 # USB Storage: Fix race when removing the SCSI host # # drivers/usb/storage/usb.c # 2004/06/13 13:09:07-07:00 mdharm-usb@one-eyed-alien.net +85 -126 # USB Storage: Fix race when removing the SCSI host # # drivers/usb/storage/transport.c # 2004/06/13 13:09:07-07:00 mdharm-usb@one-eyed-alien.net +5 -4 # USB Storage: Fix race when removing the SCSI host # # ChangeSet # 2004/06/14 10:33:05-07:00 mdharm-usb@one-eyed-alien.net # [PATCH] USB Storage: INQUIRY fixup, mode-sense options, Genesys devices # # This patch does a few things (all in the same section of code).

some bits, then writes back the new PSR. Unfortunately, the contents # of PSR may change between reading and writing it. For example, an # interrupt could occur which could trigger a context-switch. The # context-switch might in turn flush the floating-point-high (FPH) # partition to memory, clear PSR.MFH, and set PSR.DFH. To prevent this # race, the patch below turns off PSR.I before reading PSR. # # This fixes a floating-point corruption problem that was observed on a # system with a libc which has the fast system-call support enabled. # # The performance impact is minimal (on the order of a handful of cycles). # # Signed-off-by: Kevin Tian # Signed-off-by: Ken Chen # Signed-off-by: Asit Mallick # Signed-off-by: David Mosberger # # arch/ia64/kernel/gate.S # 2004/06/09 05:36:21-07:00 kenneth.w.chen@intel.com +4 -2 # ia64: fix race in fsys_bubble_down # # arch/ia64/kernel/fsys.S # 2004/06/09 05:11:54-07:00 kenneth.w.chen@intel.com +2 -1 # ia64: fix race in fsys_bubble_down # # ChangeSet # 2004/06/10 13:25:26-07:00 Robert.Picco@hp.com # [PATCH] ia64: mark non-existent NUMA-nodes as offline # # I found a problem with HP NUMA configuration in 2.6.7-rc3-mm1.

However a bus does not always have a root hub, and the code does # not check that the root_hub pointer is non-NULL. This patch fixes the # problem, using the usb_bus_list_lock semaphore to synchronize access when # root hubs are added or removed. # # In addition it seemed like a good idea to minimize the time that a # non-fully-configured root hub is accessible through the bus's pointer. So # this patch delays setting the pointer and holds usb_bus_list_lock while # configuring a root hub. # # It turned out that a bunch of things needed to be changed for all this to # work: # # Check for NULL root_hub pointer in usb_device_read() and # usb_find_device(). # # Pass the root-hub device as a separate argument to # hcd_register_root(). # # Make usb_register_root_hub() acquire the usb_bus_list_lock and # set the bus->root_hub pointer. # # For consistency's sake, move the place where the children[] # pointer to a non-root-hub device gets stored as close as possible # to where usb_new_device() is called. # # Make usb_disconnect() acquire the usb_bus_list_lock when removing # a root hub. # # Change usb_hcd_pci_remove() and the non-PCI host drivers so that # they call usb_disconnect() with a pointer to the bus's root_hub # pointer, not a pointer to a temporary variable. # # Change all the host controller drivers not to store the root_hub # pointer in the bus structure but instead to pass it as a new # argument to hcd_register_root(). # # I made some attempt to update the hc_sl811 driver along with the rest, but # it's pretty clear that driver won't work in the current framework. Among # other things, it never reads the root hub's device descriptor.

This patch attempts to put some # order back into the situation. Details: # # Since usb_new_device() allocates neither the device structure # nor the device address, it shouldn't release either one. # # Because usb_new_device() no longer releases the device structure, # usb_register_root_hub() doesn't need to take an extra reference # to it. # # Since the device address selection and TT setup code is used # only for new devices, not ones being reset, move that code from # hub_port_init() to hub_port_connect_change(). By the same token, # hub_port_init() doesn't have to release the device address or # the device structure. # # Just to make things look better, move the failure code in # hub_port_init() to the end of the routine. And when disabling # endpoint 0, disable both the IN and OUT parts of the endpoint. # # In hub_port_connect_change(), make all the failure paths # execute the same code so that resources are always released. # These resources comprise: the pointer from the parent to the # new child device, the HCD state for ep0, the device's address, # and the device structure itself -- in short, everything that's # set up before calling usb_new_device(). # # # Signed-off-by: Alan Stern # Signed-off-by: Greg Kroah-Hartman # # drivers/usb/core/hub.c # 2004/06/07 10:08:06-07:00 stern@rowland.harvard.edu +45 -50 # USB: Fix resource leakage in the hub driver # # drivers/usb/core/hcd.c # 2004/06/07 09:55:49-07:00 stern@rowland.harvard.edu +1 -3 # USB: Fix resource leakage in the hub driver # # ChangeSet # 2004/06/07 16:54:49-07:00 stern@rowland.harvard.edu # [PATCH] USB: Check port reset return code # # This patch adds checking for the SET-FEATURE request that actually does a # port reset.

Only # with the 2.6 module loader, there's no way to find out where the various # sections in the module image ended up, so you can't do much. This patch # attempts to fix that by adding a "sections" subdirectory to every module's # entry in /sys/module; each attribute in that directory associates a # beginning address with the section name. Those attributes can be used by a # a simple script to generate an add-symbol-file command for gdb, something # like: # # #!/bin/bash # # # # gdbline module image # # # # Outputs an add-symbol-file line suitable for pasting into gdb to examine # # a loaded module. # # # cd /sys/module/$1/sections # echo -n add-symbol-file $2 `/bin/cat .text` # # for section in .[a-z]* *; do # if [ $section != ".text" ]; then # echo " \\" # echo -n " -s" $section `/bin/cat $section` # fi # done # echo # # Currently, this feature is absent if CONFIG_KALLSYMS is not set.

They are: # # Increase the total timeout period from 400 ms to 1500 ms. # # Check the port's connect-changed status during the polling # loop. # # Return as soon as the connection has been stable for the # required time, even if it has been stably _dis_-connected. # (The current code waits for the full timeout period if there # isn't a connection.) # # In previous emails I have responded to all the concerns raised by others # about these changes, and I can't imagine how they could cause any trouble. # # Increasing the total timeout won't affect people with properly # functioning hardware. Their connections will quickly stabilize # and the routine will return just as before. People with flaky # hardware that takes a long time to settle down will now be able # to use their devices. # # Checking the connect-changed status during the polling loop will # make the test more conservative. The code will be able to # detect transient disconnections that it would have missed # before, and it won't return until the connection really _is_ # stable. Furthermore, this makes the test compliant with the # USB specification, which requires the stability timer to be # restarted whenever a connection change occurs. # # Returning early for disconnections is a simple optimization. # It's more important now that the total timeout length is 1.5 # seconds rather than 0.4 seconds. # # I urge you to apply this patch and for people to try it out.

The stability # period is now reported in milliseconds rather than a meaningless # poll count. # # The sleep interval is moved from the start of the loop to the # end, so that the first time through we read the port status # immediately. # # If the connection has not stabilized after the total timeout # expires, -ETIMEDOUT is returned rather than whatever the # current connect status happens to be. # # If the connection does stabilize then the port status is returned # so that hub_port_connect_change() will have an up-to-date value # for the status rather than relying on the pre-debounce value. # # The changes I wanted to make but other people were worried about are # included as comments.

Right # now the driver only does so if the status happens to be CONNECTED at one # particular instant. However, the whole point of debouncing is that the # connection is subject to transient interruptions until it has stabilized; # hence deciding whether to debounce based on a single initial test defeats # the entire purpose. # # There are some additional smaller changes that go along with the major # one: # # Comments added to hub_port_connect_change() detailing the # conditions under which it will be called. # # Don't clear the port's connect-changed feature if it wasn't # set. # # Skip debouncing if there wasn't a physical connection change # but only a logical port-enable change (or a firmware-download- # induced device morph -- not yet implemented). # # Clear all the hub status change indicators in hub_events() # before handling a connect change.

It # is now defined as a non-inline routine when debugging is enabled # and as an inline no-op otherwise (the compiler will optimize # away the useless tests). # # # Signed-off-by: Alan Stern # Signed-off-by: Greg Kroah-Hartman # # drivers/usb/core/usb.c # 2004/06/01 09:54:17-07:00 stern@rowland.harvard.edu +0 -229 # USB: Move usb_new_device() et al. into hub.c # # drivers/usb/core/hub.c # 2004/06/01 09:54:17-07:00 stern@rowland.harvard.edu +231 -3 # USB: Move usb_new_device() et al. into hub.c # # drivers/usb/core/hcd.h # 2004/06/01 09:54:17-07:00 stern@rowland.harvard.edu +0 -7 # USB: Move usb_new_device() et al. into hub.c # # ChangeSet # 2004/06/02 14:06:55-07:00 stern@rowland.harvard.edu # [PATCH] USB: Minor cleanups for hub driver # # Greg: # # This patch takes care of some small miscellaneous items in hub.c: # # Move the definition of CONFIG to the right place; # # Print the proper value for submission status in the error log; # # Remove an unused list of all hubs; # # Remove some unneeded braces; # # Kill an accidentally-resurrected comment. # # Signed-off-by: Alan Stern # Signed-off-by: Greg Kroah-Hartman # # drivers/usb/core/hub.h # 2004/06/01 09:31:11-07:00 stern@rowland.harvard.edu +0 -1 # USB: Minor cleanups for hub driver # # drivers/usb/core/hub.c # 2004/06/01 09:39:04-07:00 stern@rowland.harvard.edu +9 -25 # USB: Minor cleanups for hub driver # # ChangeSet # 2004/06/02 13:55:44-07:00 oliver@neukum.org # [PATCH] USB: fix race between disconnect and write of acm driver # # acm uses a workqueue to defer part of a write operation. # In case of disconnect this work must be waited for. # - fix race between write and disconnect # # Signed-off-by: Oliver Neukum # Signed-off-by: Vojtech Pavlik # Signed-off-by: Greg Kroah-Hartman # # drivers/usb/class/cdc-acm.c # 2004/05/31 08:13:14-07:00 oliver@neukum.org +2 -0 # USB: fix race between disconnect and write of acm driver # # ChangeSet # 2004/06/02 13:49:28-07:00 oliver@neukum.org # [PATCH] USB: fix racy access to urb->status in cdc acm driver # # Hi, # # fix access to urb->status by introduction of an explicit flag # for finished data transfer. # - fix racy access to urb->status # # Signed-off-by: Oliver Neukum # Signed-off-by: Greg Kroah-Hartman # # drivers/usb/class/cdc-acm.h # 2004/05/31 08:02:12-07:00 oliver@neukum.org +1 -0 # USB: fix racy access to urb->status in cdc acm driver # # drivers/usb/class/cdc-acm.c # 2004/05/31 08:02:12-07:00 oliver@neukum.org +10 -6 # USB: fix racy access to urb->status in cdc acm driver # # ChangeSet # 2004/06/02 13:36:24-07:00 oliver@neukum.org # [PATCH] USB: error handling of open of acm driver # # this adds error handling to the open method of the cdc acm driver. # The change set is relative to my last patch rewriting probe. # - add error handling to open method # # # Signed-off-by: Oliver Neukum # Signed-off-by: Vojtech Pavlik # Signed-off-by: Greg Kroah-Hartman # # drivers/usb/class/cdc-acm.c # 2004/05/31 06:54:36-07:00 oliver@neukum.org +23 -8 # USB: error handling of open of acm driver # # ChangeSet # 2004/06/02 13:31:54-07:00 oliver@neukum.org # [PATCH] USB: proper evaluation of the union descriptor for CDC ACM # # this changes acm_probe() to using the proper union descriptor. # It contains the workaround David suggested.

Read anticipation. - -Read anticipation occurs only when scheduling a read batch. -This implementation of read anticipation allows only one read request -to be dispatched to the disk controller at a time. In -contrast, many write requests may be dispatched to the disk controller -at a time during a write batch. It is this characteristic that can make -the anticipatory scheduler perform anomalously with controllers supporting -TCQ, or with hardware striped RAID devices. Setting the antic_expire -queue paramter (see below) to zero disables this behavior, and the anticipatory -scheduler behaves essentially like the deadline scheduler. - -When read anticipation is enabled (antic_expire is not zero), reads -are dispatched to the disk controller one at a time. -At the end of each read request, the IO scheduler examines its next -candidate read request from its sorted read list. If that next request -is from the same process as the request that just completed, -or if the next request in the queue is "very close" to the -just completed request, it is dispatched immediately. Otherwise, -statistics (average think time, average seek distance) on the process -that submitted the just completed request are examined. If it seems -likely that that process will submit another request soon, and that -request is likely to be near the just completed request, then the IO -scheduler will stop dispatching more read requests for up time (antic_expire) -milliseconds, hoping that process will submit a new request near the one -that just completed. If such a request is made, then it is dispatched -immediately. If the antic_expire wait time expires, then the IO scheduler -will dispatch the next read request from the sorted read queue. - -To decide whether an anticipatory wait is worthwhile, the scheduler -maintains statistics for each process that can be used to compute -mean "think time" (the time between read requests), and mean seek -distance for that process. One observation is that these statistics -are associated with each process, but those statistics are not associated -with a specific IO device. So for example, if a process is doing IO -on several file systems on separate devices, the statistics will be -a combination of IO behavior from all those devices. - - -Tuning the anticipatory IO scheduler ------------------------------------- -When using 'as', the anticipatory IO scheduler there are 5 parameters under -/sys/block/*/iosched/. All are units of milliseconds. - -The parameters are: -* read_expire - Controls how long until a read request becomes "expired". It also controls the - interval between which expired requests are served, so set to 50, a request - might take anywhere < 100ms to be serviced _if_ it is the next on the - expired list. Obviously request expiration strategies won't make the disk - go faster. The result basically equates to the timeslice a single reader - gets in the presence of other IO. 100*((seek time / read_expire) + 1) is - very roughly the % streaming read efficiency your disk should get with - multiple readers. - -* read_batch_expire - Controls how much time a batch of reads is given before pending writes are - served. A higher value is more efficient. This might be set below read_expire - if writes are to be given higher priority than reads, but reads are to be - as efficient as possible when there are no writes. Generally though, it - should be some multiple of read_expire. - -* write_expire, and -* write_batch_expire are equivalent to the above, for writes. - -* antic_expire - Controls the maximum amount of time we can anticipate a good read (one - with a short seek distance from the most recently completed request) before - giving up. Many other factors may cause anticipation to be stopped early, - or some processes will not be "anticipated" at all. Should be a bit higher - for big seek time devices though not a linear correspondence - most - processes have only a few ms thinktime. - diff -Nru a/Documentation/binfmt_misc.txt b/Documentation/binfmt_misc.txt --- a/Documentation/binfmt_misc.txt 2004-06-23 19:04:29 -07:00 +++ b/Documentation/binfmt_misc.txt 2004-06-23 19:04:29 -07:00 @@ -15,7 +15,7 @@ mount binfmt_misc -t binfmt_misc /proc/sys/fs/binfmt_misc To actually register a new binary type, you have to set up a string looking like -:name:type:offset:magic:mask:interpreter: (where you can choose the ':' upon +:name:type:offset:magic:mask:interpreter:flags (where you can choose the ':' upon your needs) and echo it to /proc/sys/fs/binfmt_misc/register.

In the case a read batch, the scheduler submits read +requests to the driver as long as there are read requests to submit, and +the read batch time limit has not been exceeded (read_batch_expire). +The read batch time limit begins counting down only when there are +competing write requests pending. + +In the case of a write batch, the scheduler submits write requests to +the driver as long as there are write requests available, and the +write batch time limit has not been exceeded (write_batch_expire). +However, the length of write batches will be gradually shortened +when read batches frequently exceed their time limit. + +When changing between batch types, the scheduler waits for all requests +from the previous batch to complete before scheduling requests for the +next batch. + +The read and write fifo expiration times described in policy 2 above +are checked only when in scheduling IO of a batch for the corresponding +(read/write) type. So for example, the read FIFO timeout values are +tested only during read batches. Likewise, the write FIFO timeout +values are tested only during write batches. For this reason, +it is generally not recommended for the read batch time +to be longer than the write expiration time, nor for the write batch +time to exceed the read expiration time (see tunable parameters below). + +When the IO scheduler changes from a read to a write batch, +it begins the elevator from the request that is on the head of the +write expiration FIFO. Likewise, when changing from a write batch to +a read batch, scheduler begins the elevator from the first entry +on the read expiration FIFO. + +4. Read anticipation. + +Read anticipation occurs only when scheduling a read batch. +This implementation of read anticipation allows only one read request +to be dispatched to the disk controller at a time. In +contrast, many write requests may be dispatched to the disk controller +at a time during a write batch. It is this characteristic that can make +the anticipatory scheduler perform anomalously with controllers supporting +TCQ, or with hardware striped RAID devices. Setting the antic_expire +queue paramter (see below) to zero disables this behavior, and the anticipatory +scheduler behaves essentially like the deadline scheduler. + +When read anticipation is enabled (antic_expire is not zero), reads +are dispatched to the disk controller one at a time. +At the end of each read request, the IO scheduler examines its next +candidate read request from its sorted read list. If that next request +is from the same process as the request that just completed, +or if the next request in the queue is "very close" to the +just completed request, it is dispatched immediately. Otherwise, +statistics (average think time, average seek distance) on the process +that submitted the just completed request are examined. If it seems +likely that that process will submit another request soon, and that +request is likely to be near the just completed request, then the IO +scheduler will stop dispatching more read requests for up time (antic_expire) +milliseconds, hoping that process will submit a new request near the one +that just completed. If such a request is made, then it is dispatched +immediately. If the antic_expire wait time expires, then the IO scheduler +will dispatch the next read request from the sorted read queue. + +To decide whether an anticipatory wait is worthwhile, the scheduler +maintains statistics for each process that can be used to compute +mean "think time" (the time between read requests), and mean seek +distance for that process. One observation is that these statistics +are associated with each process, but those statistics are not associated +with a specific IO device. So for example, if a process is doing IO +on several file systems on separate devices, the statistics will be +a combination of IO behavior from all those devices. + + +Tuning the anticipatory IO scheduler +------------------------------------ +When using 'as', the anticipatory IO scheduler there are 5 parameters under +/sys/block/*/iosched/. All are units of milliseconds. + +The parameters are: +* read_expire + Controls how long until a read request becomes "expired". It also controls the + interval between which expired requests are served, so set to 50, a request + might take anywhere < 100ms to be serviced _if_ it is the next on the + expired list. Obviously request expiration strategies won't make the disk + go faster. The result basically equates to the timeslice a single reader + gets in the presence of other IO. 100*((seek time / read_expire) + 1) is + very roughly the % streaming read efficiency your disk should get with + multiple readers. + +* read_batch_expire + Controls how much time a batch of reads is given before pending writes are + served. A higher value is more efficient. This might be set below read_expire + if writes are to be given higher priority than reads, but reads are to be + as efficient as possible when there are no writes. Generally though, it + should be some multiple of read_expire. + +* write_expire, and +* write_batch_expire are equivalent to the above, for writes. + +* antic_expire + Controls the maximum amount of time we can anticipate a good read (one + with a short seek distance from the most recently completed request) before + giving up. Many other factors may cause anticipation to be stopped early, + or some processes will not be "anticipated" at all. Should be a bit higher + for big seek time devices though not a linear correspondence - most + processes have only a few ms thinktime. + diff -Nru a/Documentation/block/deadline-iosched.txt b/Documentation/block/deadline-iosched.txt --- /dev/null Wed Dec 31 16:00:00 196900 +++ b/Documentation/block/deadline-iosched.txt 2004-06-23 19:04:29 -07:00 @@ -0,0 +1,78 @@ +Deadline IO scheduler tunables +============================== + +This little file attempts to document how the deadline io scheduler works. +In particular, it will clarify the meaning of the exposed tunables that may be +of interest to power users. + +Each io queue has a set of io scheduler tunables associated with it.

A +request is either qualified as a seek or a stream. The io scheduler knows +the last request that was serviced by the drive (or will be serviced right +before this one).

Do only select one of them in your kernel +configuration. + + +How are parameters passed to sisfb? +=================================== + +Well, it depends: If compiled statically into the kernel, use lilo's append +statement to add the parameters to the kernel command line. Please see lilo's +(or GRUB's) documentation for more information. If sisfb is a kernel module, +parameters are given with the modprobe (or insmod) command. + +Example for sisfb as part of the static kernel: Add the following line to your +lilo.conf: + + append="video=sisfb:mode:1024x768x16,mem:12288,rate:75" + +Example for sisfb as a module: Start sisfb by typing + + modprobe sisfb mode=1024x768x16 rate=75 mem=12288 + +A common mistake is that folks use a wrong parameter format when using the +driver compiled into the kernel.

Please refer to the author's and maintainer's +website at http://www.winischhofer.net/linuxsisvga.shtml for more +information. Additionally, "modinfo sisfb" gives an overview over all +supported options including some explanation. + +The desired display mode can be specified using the keyword "mode" with +a parameter in one of the follwing formats: + - XxYxDepth or + - XxY-Depth or + - XxY-Depth@Rate or + - XxY + - or simply use the VESA mode number in hexadecimal or decimal. + +For example: 1024x768x16, 1024x768-16@75, 1280x1024-16. If no depth is +specified, it defaults to 8. If no rate is given, it defaults to 60Hz. Depth 32 +means 24bit color depth (but 32 bit framebuffer depth, which is not relevant +to the user). + +Additionally, sisfb understands the keyword "vesa" followed by a VESA mode +number in decimal or hexadecimal. For example: vesa=791 or vesa=0x117. Please +use either "mode" or "vesa" but not both. + +Linux 2.4 only: If no mode is given, sisfb defaults to "no mode" (mode=none) if +compiled as a module; if sisfb is statically compiled into the kernel, it +defaults to 800x600x8 unless CRT2 type is LCD, in which case the LCD's native +resolution is used. If you want to switch to a different mode, use the fbset +shell command. + +Linux 2.6 only: If no mode is given, sisfb defaults to 800x600x8 unless CRT2 +type is LCD, in which case it defaults to the LCD's native resolution. If +you want to switch to another mode, use the stty shell command. + +You should compile in both vgacon (to boot if you remove you SiS card from +your system) and sisfb (for graphics mode). Under Linux 2.6, also "Framebuffer +console support" (fbcon) is needed for a graphical console. + +You should *not* compile-in vesafb. And please do not use the "vga=" keyword +in lilo's or grub's configuration file; mode selection is done using the +"mode" or "vesa" keywords as a parameter.
