# [PATCH] dentry_stat accounting fix
# 
# From: Maneesh Soni <maneesh@in.ibm.com>
# 
# This patch the corrects the dentry_stat.nr_unused calculation.
# 
# In select_parent() and shrink_dcache_anon() we were not doing any adjustments
# to the nr_unused count after manipulating the dentry_unused list.  Now the
# nr_unused count is decremented if the dentry is on dentry_unused list and is
# removed from there.
# 
# Further in the same routines, we have to adjust the nr_unused count again if
# the dentry is moved to the end of d_lru list for pruning.
# --------------------------------------------
# 03/04/20	akpm@digeo.com	1.1118.5.5
# [PATCH] Fix and clean up DCACHE_REFERENCED usage
# 
# From: Maneesh Soni <maneesh@in.ibm.com>
# 
# This patch changes the way DCACHE_REFERENCED flag is used. It
# got messed up in dcache_rcu iterations. I hope this will be ok now.
# 
# The flag was meant to be advisory flag which is used while
# prune_dcache() so as not to free dentries which have recently
# entered d_lru list. At first pass in prune_dcache the dentries
# marked DCACHE_REFERENCED are left with the flag reset. and they
# are freed in the next pass.
# 
# So, now we mark the dentry as DCACHE_REFERENCED when it is first
# entering the d_lru list in dput() and resetthe flag in prune_dcache().
# If the flag remains reset in the next call to prune_dcache(), the
# dentry is then freed.
# 
# Also I don't think any file system have to use this flag as it is taken
# care by the dcache layer. The patch removes such code from a few of file
# systems. Moreover these filesystems were anyway doing worng thing as they
# were changing the flag out of dcache_lock.
# 
# Changes:
# o dput() marks dentry DCACHE_REFERENCED when it is added to the dentry_unused
#   list
# o no need to set the flag in dget, dget_locked, d_lookup as these guys anyway
#   increments the ref count.
# o check the ref count in prune_dcache and use DCACHE_REFERENCED flag just for
#   two stage aging.
# o remove code for setting DACACHE_REFERENCED from reiserfs, fat, xfs and
#   exportfs.

# [PATCH] Fix POSIX timers to give CLOCK_MONOTONIC full
# 
# The POSIX CLOCK_MONOTONIC currently has only 1/HZ resolution.  Further, it is
# tied to jiffies (i.e.  is a restatment of jiffies) rather than "xtime" or the
# gettimeofday() clock.
# 
# This patch changes CLOCK_MONOTONIC to be a restatment of gettimeofday() plus
# an offset to remove any clock setting activity from CLOCK_MONOTONIC.  An
# offset is kept that represents the difference between CLOCK_MONOTONIC and
# gettimeofday().  This offset is updated when ever the gettimeofday() clock is
# set to back the clock setting change out of CLOCK_MONOTONIC (which by the
# standard, can not be set).
# 
# With this change CLOCK_REALTIME (a direct restatement of gettimeofday()),
# CLOCK_MONOTONIC and gettimeofday() will all tick at the same time and with
# the same rate.  And all will be affected by NTP adjustments (save those which
# actually set the time).
# --------------------------------------------
# 03/04/20	akpm@digeo.com	1.1118.5.7
# [PATCH] Fix jiffies_to_time[spec | val] and converse to use
# 
# From: george anzinger <george@mvista.com>
# 
# In the current system (2.5.67) time_spec to jiffies, time_val to
# jiffies and the converse (jiffies to time_val and jiffies to
# time_spec) all use 1/HZ as the measure of a jiffie.  Because of the
# inability of the PIT to actually generate an accurate 1/HZ interrupt,
# the wall clock is updated with a more accurate value (999848
# nanoseconds per jiffie for HZ = 1000).  This causes a 1/HZ
# interpretation of jiffies based timing to run faster than the wall
# clock, thus causing sleeps and timers to expire short of the requested
# time.  Try, for example:
# 
# time sleep 60
# 
# This patch changes the conversion routines to use the same value as
# the wall clock update code to do the conversions.
# 
# The actual math is almost all done at compile time.  The run time
# conversions require little if any more execution time.
# 
# This patch must be applied after the patch I posted earlier today
# which fixed the CLOCK_MONOTONIC resolution issue.

# 03/04/20	akpm@digeo.com	1.1118.5.8
# [PATCH] get_offset_pit and do_timer_overflow vs IRQ locking
# 
# From: john stultz <johnstul@us.ibm.com>, Alexander Atanasov <alex@ssi.bg>
# 
# We want to make sure we update jiffies_p and count_p atomically.  So I'm
# inserting the spin_unlock_irqrestore() after we update count_p, rather then
# just before.

# 03/04/20	akpm@digeo.com	1.1118.5.9
# [PATCH] detect_lost_tick locking fixes
# 
# From: john stultz <johnstul@us.ibm.com>
# 
# This patch fixes a race in the timer_interrupt code caused by
# detect_lost_tick().  Since we're doing lost-tick compensation outside
# timer->mark_offset, time can pass between time-source reads which can cause
# gettimeofday inconsistencies.
# 
# Additionally detect_lost_tick() was broken for the PIT case, since the whole
# point of detect_lost_tick() is to interpolate between two time sources to
# find inconsistencies.  Additionally this could cause xtime_lock seq_lock
# reader starvation which has been causing machine hangs for SMP boxes that use
# the PIT as a time source.
# 
# This patch fixes the described race by removing detect_lost_tick() and
# instead implementing the lost tick detection code inside mark_offset().
# 
# Some of the divs and mods being added here might concern folks, but by not
# calling timer->get_offset() in detect_lost_tick() we eliminate much of the
# same math.  I did some simple cycle counting and the new code comes out on
# average equivalent or faster.

# [PATCH] Make PCI scanning order the same as 2.4
# 
# From: Chuck Ebbert <76306.1226@compuserve.com>
# 
# 2.4 builds its global PCI device list in breadth-first order.
# 
# 2.5 is doing the scan that way but defers the construction of the global list
# until later and then does it depth-first.  This causes devices to found in
# different order by drivers.  The below fixed that problem for me.

# Russell King has acked this change.

# it would rebalance too agressively.  That seems to be fixed now, so we should

# From: William Lee Irwin III <wli@holomorphy.com>
# 
# follow_hugetlb_page() drops out of the loop prematurely and fails to take the
# appropriate refcounts if its starting address was not hugepage-aligned.
# 
# It looked a bit unclean too, so I rewrote it.  This fixes a bug, and more
# importantly, makes the thing readable by something other than a compiler
# (e.g.  programmers).

# [PATCH] shmdt() speedup
# 
# From: William Lee Irwin III <wli@holomorphy.com>
# 
# Micro-optimize sys_shmdt(). There are methods of exploiting knowledge
# of the vma's being searched to restrict the search space. These are:
# 
# (1) shm mappings always start their lives at file offset 0, so only
# 	vma's above shmaddr need be considered. find_vma() can be used
# 	to seek to the proper position in mm->mmap in O(lg(n)) time.
# 
# (2) The search is for a vma which could be a fragment of a broken-up
# 	shm mapping, which would have been created starting at shmaddr
# 	with vm_pgoff 0 and then continued no further into userspace
# 	than shmaddr + size. So after having found an initial vma, find
# 	the size of the shm segment it maps to calculate an upper bound
# 	to the virtualspace that needs to be searched.
# 
# (3) mremap() would have caused the original checks to miss vma's mapping
# 	the shm segment if shmaddr were the original address at which
# 	the shm segments were attached. This does no better and no worse
# 	than the original code in that situation.
# 
# (4) If the chain of references in vma->vm_file->f_dentry->d_inode->i_size
# 	is not guaranteed by refcounting and/or the shm code then this is
# 	oopsable; AFAICT an inode is always allocated.

# [PATCH] implement __GFP_REPEAT, __GFP_NOFAIL, __GFP_NORETRY
# 
# This is a cleanup patch.
# 
# There are quite a lot of places in the kernel which will infinitely retry a
# memory allocation.
# 
# Generally, they get it wrong.  Some do yield(), the semantics of which have
# changed over time.  Some do schedule(), which can lock up if the caller is
# SCHED_FIFO/RR.  Some do schedule_timeout(), etc.
# 
# And often it is unnecessary, because the page allocator will do the retry
# internally anyway.  But we cannot rely on that - this behaviour may change
# (-aa and -rmap kernels do not do this, for instance).
# 
# So it is good to formalise and to centralise this operation.  If an
# allocation specifies __GFP_REPEAT then the page allocator must infinitely
# retry the allocation.
# 
# The semantics of __GFP_REPEAT are "try harder".  The allocation _may_ fail
# (the 2.4 -aa and -rmap VM's do not retry infinitely by default).
# 
# The semantics of __GFP_NOFAIL are "cannot fail".  It is a no-op in this VM,
# but needs to be honoured (or fix up the callers) if the VM ischanged to not
# retry infinitely by default.
# 
# The semantics of __GFP_NOREPEAT are "try once, don't loop".  This isn't used
# at present (although perhaps it should be, in swapoff).  It is mainly for
# completeness.
# --------------------------------------------
# 03/04/20	akpm@digeo.com	1.1118.5.23
# [PATCH] make alloc_buffer_head take gfp_flags
# 
# - alloc_buffer_head() should take the allocation mode as an arg, and not
#   assume.

# 
# - Remove all the retry code from jbd_kmalloc() - do it via page allocator

# [PATCH] Disallow swapoff if there is insufficient memory
# 
# From: Hugh Dickins <hugh@veritas.com>
# 
# First of three small "stop swapoff" patches based on 2.5.67-mm3:
# 
# stop swapoff 1/3 vm_enough_memory?
# 
# Before embarking upon swapoff, check vm_enough_memory.  Mainly
# for consistency in the overcommit_memory 2 (strict accounting) case:
# fail with -ENOMEM if it wouldn't let the amount removed be committed.
# 
# Will always succeed in the overcommit_memory 1 case, as it should in
# root-shoot-foot mode.  In the overcommit_memory 0 case, well, I don't
# care much either way, so opted for the simplest code: no special case.
# Which means it could now fail at the start; but that's unlikely (case 0
# is over-generous) and only when it would have got stuck later on anyway.

# [PATCH] oom-kill: preferentially kill swapoff
# 
# From: Hugh Dickins <hugh@veritas.com>
# 
# The current behaviour is that once swapoff has filled memory, other tasks get
# OOMkilled one by one until swapoff completes, or more likely hangs.  It is
# better that swapoff be the first choice for OOMkill.
# 
# The patch changes the oom-killer so that it will kill off any
# currently-running swapoff instance before killing any other task.

# [PATCH] Allocate hd_structs dynamically
# 
# From: Badari Pulavarty <pbadari@us.ibm.com>
# 
# Here is the patch to allocate hd_struct dynamically as we find
# partitions.
# 
# There are 3 things I didn't like in the patch.
# 
# 1) The patch allocates 15 pointers instead of 15 hd_structs.  (incase of
#    s= csi).  I was really hoping to get rid of "15" and make it really
#    dynamic.  (In ca= se if we ever want to support more than 15 partitions
#    per disk etc..).=20 I was thought about making it a linked list, but
#    blk_partition_remap() needs to get to hd_struct for a given partition
#    everytime we do IO.  So linked list would be bad, we really need direct
#    access to partition in= fo.
# 
# 2) I had to add "partno" to hd_struct, since part_dev_read() used to calc=
#    ulate partition number from the address before.
# 
# 3) kmalloc() failure in add_partition() will be silently ignored.
# 
# It saves 2048 bytes per disk.

# [PATCH] don't shrink slab for highmem allocations
# 
# From: William Lee Irwin III <wli@holomorphy.com>
# 
# If one's goal is to free highmem pages, shrink_slab() is an ineffective
# method of recovering them, as slab pages are all ZONE_NORMAL or ZONE_DMA.
# Hence, this "FIXME: do not do for zone highmem".  Presumably this is a
# question of policy, as highmem allocations may be satisfied by reaping slab
# pages and handing them back; but the FIXME says what we should do.

# [PATCH] trivial task_prio() fix
# 
# Here is a trivial fix for task_prio() in the case MAX_RT_PRIO !=
# MAX_USER_RT_PRIO.  In this case, all priorities are skewed by
# (MAX_RT_PRIO - MAX_USER_RT_PRIO).
# 
# The fix is to subtract the full MAX_RT_PRIO value from p->prio, not just
# MAX_USER_RT_PRIO.  This makes sense, as the full priority range is
# unrelated to the maximum user value.  Only the real maximum RT value
# matters.
# 
# This has been in Andrew's tree for awhile, with no issue.  Also, Ingo
# acked it.

# [PATCH] More careful about VMA merging
# 
# The VMA merging code can merge vmas which have a ->vm_ops->close() handler.
# But this means that per-VMA resources in one of the merged VMAs will not be
# freed.
# 
# Fix that up by just refusing to merge any VMA's which look "complex": they
# have special flags set or they have a ->close handler.

# [PATCH] Runtime memory barrier patching
# 
# This implements automatic code patching of memory barriers based
# on the CPU capabilities. Normally lock ; addl $0,(%esp) barriers
# are used, but these are a bit slow on the Pentium 4.
# 
# Linus proposed this a few weeks ago after the support for SSE1/SSE2
# barriers was introduced. I now got around to implement it.
# 
# The main advantage is that it allows distributors to ship less binary
# kernels but still get fast kernels. In particular it avoids the
# need of a special Pentium 4 kernel.
# 
# The patching code is quite generic and could be used to patch
# other instructions (like prefetches or specific other critical
# instructions) too.
# Thanks to Rusty's in kernel loader it also works seamlessly for modules.
# 
# The patching is done before other CPUs start to avoid potential
# erratas with self modifying code on SMP systems. It makes no
# attempt to automatically handle assymetric systems (an secondary
# CPU having less capabilities than the boot CPU). In this
# case just boot with "noreplacement"

# [PCMCIA] Fix oops in validate_mem when CONFIG_PCMCIA_PROBE=n
# 
# If I compile a recent 2.5.x kernel without CONFIG_ISA defined, I get
# an oops in validate_mem().  Stack trace contains 0x6b6b6b6 - a clear
# sign that freed memory is being accessed.
# 
# It's the second validate_mem() in drivers/pcmcia/rsrc_mgr.c - the one
# used when CONFIG_PCMCIA_PROBE is not defined.  It turns out the memory
# is freed in do_mem_probe() when it's called from validate_mem().
# 
# The solution is to use the same trick as in the first validate_mem().
# This problem is quite serious and it's not specific to the plx9052
# driver. I see it with yenta_socket as well.

# 03/04/23	rmk@flint.arm.linux.org.uk	1.1118.27.4
# [PCMCIA] Don't cache CIS bytes found to be invalid.
# 
# Several PCMCIA cards I have here do not work correctly over a
# suspend/resume cycle; the PCMCIA code believes that the card has
# been changed in the slot, and therefore performs a remove/insert
# cycle.
# 
# This seems to be because the card returns more or less random data
# when reading memory space, leading to the CIS cache mismatching
# the card data.  This in turn is caused because we try to read CIS
# data from both the attribute and memory spaces, and we add the result
# to the CIS cache whether or not the returned data was valid.
# 
# We therefore convert the CIS cache to use a linked list, and provide
# a way to remove cached data from that list.  We also replace the
# "s->cis_used=0;" construct with a function "destroy_cis_cache(s)"
# which clearly describes what we're doing.

# 03/04/23	rmk@flint.arm.linux.org.uk	1.1118.27.5
# [PCMCIA] Make cb_release_cis_mem() local to cardbus.c
# 
# The cardbus CIS parsing code does not use the PCMCIA resource
# subsystem, so there isn't any point in freeing its memory when
# we remove PCMCIA memory resources.  We also free CIS resources
# immediately prior to calling cb_free().  We might as well move
# the function call into cb_free(), thereby making all references
# to cb_release_cis_mem() local to cardbus.c

# proc_print_scsidevice is used for the scsi device listing in

# [PATCH] 2.5.68 scsi/gdth compile warnings and stack usage
# 
# James Bottomley, please apply this patch.  It was sent out on
# linux-scsi last week and drew no responses.
# 
# This is a patch for the scsi/gdth driver.  It was originally
# done in 2.5.67, but the patch applies to 2.5.68.
# 
# There are two components to this patch.  The first component fixes
# with compilation warnings (which did uncover real bugs).  The other component
# (by Randy Dunlap) reduces stack size usage in gdth_ioctl().
# 
# The compilation warnings occur only when CONFIG_HIGHMEM=y in the kernel
# configuration file (enable either 4gig or 64gig memory support).  This
# changes the size of the dma_addr_t from u32 to u64.
# The calls to pci_alloc_consistent return a value of type dma_addr_t.
# But the code was casting a pointer to what was ony a 32-bit memory location.
# 
# This seonc component of the patch reduces stack size in
# scsi/gdth.c::gdth_ioctl() by making each separate ioctl have its own
# handler function, so that several large data structs are all declared on
# the stack at the same time.
# 
# patch_name:     gdth-stack_warnings.patch
# patch_version:  2003-04-14.16:31:30
# author:         Randy.Dunlap <rddunlap@osdl.org>, Dave.Olien<dmo@osdl.org)
# description:    reduce stack usage in drivers/scsi/gdth.c::gdth_ioctl()
#                 from 0xb50 to 0x5c (on P4, gcc 2.96); the large (ioctl)
#                 function sizes in gdth.o now are:
#                         150 ioc_event
#                         178 ioc_resetdrv
#                         190 ioc_general
#                         30c ioc_hdrlist
#                         324 ioc_rescan
#                 so the largest cumulative size of calling gdth_ioctl() +
#                 a specific ioctl is 0x5c + 0x324 = 0x380.
# 		Fix compilation warnings in calls to pci_alloc_consistent()
# 		that occur only when CONFIG_HIGHMEM=y.  The compiler
# 		warnings result from dma_addr_t changing in size from u32
# 		to u64.
# product:        Linux
# product_versions: 2.5.67
# changelog:      make each ioctl that uses large stack space into its own
#                 function;
#                 mostly moving lines of code around;
#                 duplicates some local data in multiple functions;
# 		fix compiler warnings by adding intermediate dma_addr_t local
# 		variables to hold returns from pci_alloc_consistent.

# [PATCH] console cleanup (1/2)

# 	Preparation to console->device() cleanup: serial drivers converted

# --------------------------------------------
# 03/04/24	viro@parcelfarce.linux.theplanet.co.uk	1.1118.31.10
# [PATCH] console cleanup (2/2)
# 
# 	Console drivers cleanup.  In current tree interaction between
# console and tty layer sits in the ->device() method of struct console.
# It takes a pointer to console and returns device number of its tty
# device.  open(2) on /dev/console goes through the list of registered
# consoles, picks the first one that has ->device() and remaps the device
# number to console->device(console).  Then it proceeds with normal
# opening of tty.  This is the only caller of ->device().
# 
# 	Cleanup: let ->device() return a pair (pointer to tty_driver, index
# of tty in question) instead of device number.  Note that
# 	a) the first thing tty_open() does with remapped device number is
# conversion to such pair.
# 	b) console driver _knows_ which tty_driver we want - one that
# implements tty interface to the same physical device (i.e. the part of
# the same driver).
# 	c) current code expects the result of ->device() to be a device
# number of tty device - anything else is immediate -ENODEV from tty_open();
# might as well have NULL ->device in that driver.
# 
# 	Console drivers converted, (the only) caller updated.

# [PATCH] fbdev cleanup

# have register_framebuffer() which sets .node to mk_kdev(FB_MAJOR, index)
# already called and all of them start with applying minor().  IOW, what
# they actually want is framebuffer number.
# 
# 	* type of ->node changed to int
# 	* register_framebuffer() sets it to index instead of mk_kdev(...)
# 	* users converted from minor(foo.node) to foo.node
# 	* useless assignments (typically to NODEV) removed - we never
# look at that field before register_framebuffer() overwrites it and thus
# any assignments prior to register_framebuffer() call are dead code.

# [PATCH] invalidate_device()/check_disk_change() fixes
# 
# 	* bogus calls of invalidate_buffers() gone from floppy_open()
# 	* invalidate_buffers() killed.
# 
# 	* new helper - __invalidate_device(bdev, do_sync).  invalidate_device()
# is calling it.
# 
# 	* fixed races between floppy_open()/floppy_open and
# floppy_open()/set_geometry():
# 	a) floppy_open()/floppy_release() is done under a semaphore.  That
# closes the races between simultaneous open() on /dev/fd0foo and /dev/fd0bar.
# 	b) pointer to struct block_device is kept as long as floppy is
# opened (per-drive, non-NULL when number of openers is non-zero, does not
# contribute to block_device refcount).
# 	c) set_geometry() grabs the same semaphore and invalidates the
# devices directly instead of messing with setting fake "it had changed"
# and calling __check_disk_change().
# 
# 	* __check_disk_change() killed - no remaining callers
# 	* full_check_disk_change() killed - ditto.

# [PATCH] ppc boot device selection cleanup
# 
# 	PPC logics for choice of default boot device number switched to
# dev_t.  Rationale: it belongs to userland; we notice partitions with
# certain properties and choose one of them as the best candidate for
# being a root fs; then we put the resulting device number into ROOT_DEV,
# which has only one use - it's passed to mknod(2) to create a device node
# on rootfs and allow mount(2) get us the final root.
# 
# 	IOW, all that code has nothing whatsoever with kernel internals
# of any description - the value we are generating will be passed to
# mknod(2) anyway.  Switched to dev_t.
# 
# 	Note: that code should eventually be moved to early userland.

# [PATCH] simple_fill_super()
# 
# 	New libfs.c helper - simple_fill_super().  Abstracted from
# nfsd/nfsctl.c, couple of filesystems converted to it (nfsctl, binfmt_misc).
# 
# 	Function takes an array of triples (name, file_operations, mode),
# superblock and value for its ->s_magic.  It acts as fill_super() - populates
# superblock or fails.  We get a ramfs-style flat tree - root directory and
# a bunch of files in it.
# 
# 	That animal allows to put together a simple filesystem without
# touching any directory-related stuff - now it's as easy as implementing
# file_operations for files you want to have and telling what to call them.

+
+Command Line Parameters
+=======================
+
+If the driver is built as a module, the  following optional parameters are 
+used by entering them on the command line with the modprobe or insmod command
+using this syntax:
+
+     modprobe ixgb [<option>=<VAL1>,<VAL2>,...]
+
+     insmod ixgb [<option>=<VAL1>,<VAL2>,...]
+
+For example, with two PRO/10GbE PCI adapters, entering:
+
+    insmod ixgb TxDescriptors=80,128
+
+loads the ixgb driver with 80 TX resources for the first adapter and 128 TX 
+resources for the second adapter.
+
+The default value for each parameter is generally the recommended setting,
+unless otherwise noted.
+
+
+FlowControl
+Valid Range: 0-3 (0=none, 1=Rx only, 2=Tx only, 3=Rx&Tx)
+Default: Read from the EEPROM
+         If EEPROM is not detected, default is 3
+    This parameter controls the automatic generation(Tx) and response(Rx) to 
+    Ethernet PAUSE frames.
+
+RxDescriptors
+Valid Range: 64-4096
+Default Value: 1024
+    This value is the number of receive descriptors allocated by the driver. 
+    Increasing this value allows the driver to buffer more incoming packets. 
+    Each descriptor is 16 bytes.  A receive buffer is also allocated for 
+    each descriptor and can be either 2048, 4056, 8192, or 16384 bytes, 
+    depending on the MTU setting. When the MTU size is 1500 or less, the 
+    receive buffer size is 2048 bytes. When the MTU is greater than 1500 the
+    receive buffer size will be either 4056, 8192, or 16384 bytes. The 
+    maximum MTU size is 16114.
+
+RxIntDelay
+Valid Range: 0-65535 (0=off)
+Default Value: 6
+    This value delays the generation of receive interrupts in units of 
+    0.8192 microseconds.  Receive interrupt reduction can improve CPU 
+    efficiency if properly tuned for specific network traffic. Increasing 
+    this value adds extra latency to frame reception and can end up 
+    decreasing the throughput of TCP traffic. If the system is reporting 
+    dropped receives, this value may be set too high, causing the driver to 
+    run out of available receive descriptors.
+
+TxDescriptors
+Valid Range: 64-4096
+Default Value: 256
+    This value is the number of transmit descriptors allocated by the driver.
+    Increasing this value allows the driver to queue more transmits. Each 
+    descriptor is 16 bytes.
+
+XsumRX
+Valid Range: 0-1
+Default Value: 1
+    A value of '1' indicates that the driver should enable IP checksum
+    offload for received packets (both UDP and TCP) to the adapter hardware.
+
+XsumTX
+Valid Range: 0-1
+Default Value: 1
+    A value of '1' indicates that the driver should enable IP checksum
+    offload for transmitted packets (both UDP and TCP) to the adapter 
+    hardware.
+
+
+Improving Performance
+=====================
+
+With the Intel PRO/10 GbE adapter, the default Linux configuration will very 
+likely limit the total available throughput artificially.  There is a set of 
+things that when applied together increase the ability of Linux to transmit 
+and receive data.  The following enhancements were originally acquired from
+settings published at http://www.spec.org/web99 for various submitted results 
+using Linux.
+
+NOTE: These changes are only suggestions, and serve as a starting point for 
+tuning your network performance.
+
+The changes are made in three major ways, listed in order of greatest effect:
+- Use ifconfig to modify the mtu (maximum transmission unit) and the txqueuelen 
+  parameter.
+- Use sysctl to modify /proc parameters (essentially kernel tuning)
+- Use setpci to modify the MMRBC field in PCI-X configuration space to increase 
+  transmit burst lengths on the bus.
+
+NOTE: setpci modifies the adapter's configuration registers to allow it to read 
+up to 4k bytes at a time (for transmits).  However, for some systems the 
+behavior after modifying this register may be undefined (possibly errors of some 
+kind). A power-cycle, hard reset or explicitly setting the e6 register back to 
+22 (setpci -d 8086:1048 e6.b=22) may be required to get back to a stable 
+configuration.
+
+- COPY these lines and paste them into ixgb_perf.sh:
+#!/bin/bash
+echo "configuring network performance , edit this file to change the interface"
+# set mmrbc to 4k reads, modify only Intel 10GbE device IDs
+setpci -d 8086:1048 e6.b=2e
+# set the MTU (max transmission unit) - it requires your switch and clients to change too!
+# set the txqueuelen
+# your ixgb adapter should be loaded as eth1 for this to work, change if needed
+ifconfig eth1 mtu 9000 txqueuelen 1000 up
+# call the sysctl utility to modify /proc/sys entries 
+sysctl -p ./sysctl_ixgb.conf 
+- END ixgb_perf.sh
+
+- COPY these lines and paste them into sysctl_ixgb.conf:
+# some of the defaults may be different for your kernel
+# call this file with sysctl -p <this file>
+# these are just suggested values that worked well to increase throughput in
+# several network benchmark tests, your mileage may vary
+
+### IPV4 specific settings
+net.ipv4.tcp_timestamps = 0 # turns TCP timestamp support off, default 1, reduces CPU use
+net.ipv4.tcp_sack = 0 # turn SACK support off, default on
+# on systems with a VERY fast bus -> memory interface this is the big gainer 
+net.ipv4.tcp_rmem = 10000000 10000000 10000000 # sets min/default/max TCP read buffer, default 4096 87380 174760
+net.ipv4.tcp_wmem = 10000000 10000000 10000000 # sets min/pressure/max TCP write buffer, default 4096 16384 131072
+net.ipv4.tcp_mem = 10000000 10000000 10000000 # sets min/pressure/max TCP buffer space, default 31744 32256 32768
+
+### CORE settings (mostly for socket and UDP effect)
+net.core.rmem_max = 524287 # maximum receive socket buffer size, default 131071
+net.core.wmem_max = 524287 # maximum send socket buffer size, default 131071
+net.core.rmem_default = 524287 # default receive socket buffer size, default 65535
+net.core.wmem_default = 524287 # default send socket buffer size, default 65535
+net.core.optmem_max = 524287 # maximum amount of option memory buffers, default 10240
+net.core.netdev_max_backlog = 300000 # number of unprocessed input packets before kernel starts dropping them, default 300
+- END sysctl_ixgb.conf
+
+Edit the ixgb_perf.sh script if necessary to change eth1 to whatever interface 
+your ixgb driver is using.
+
+NOTE: Unless these scripts are added to the boot process, these changes will 
+only last only until the next system reboot.
+
+
+Resolving Slow UDP Traffic
+--------------------------
+
+If your server does not seem to be able to receive UDP traffic as fast as it 
+can receive TCP traffic, it could be because Linux, by default, does not set 
+the network stack buffers as large as they need to be to support high UDP 
+transfer rates. One way to alleviate this problem is to allow more memory to 
+be used by the IP stack to store incoming data. 
+
+For instance, use the commands: 
+    sysctl -w net.core.rmem_max=262143
+and
+    sysctl -w net.core.rmem_default=262143
+to increase the read buffer memory max and default to 262143 (256k - 1) from 
+defaults of max=131071 (128k - 1) and default=65535 (64k - 1). These variables 
+will increase the amount of memory used by the network stack for receives, and 
+can be increased significantly more if necessary for your application.

+README file for the dc395x SCSI driver
+==========================================
+
+Status
+------
+The driver has been tested with CD-R and CD-R/W drives. These should
+be safe to use. Testing with hard disks has not been done to any
+great degree and caution should be exercised if you want to attempt
+to use this driver with hard disks.
+
+This is a 2.5 only driver. For a 2.4 driver please see the original
+driver (which this driver started from) at
+http://www.garloff.de/kurt/linux/dc395/
+
+Problems, questions and patches should be submitted to the mailing
+list. Details on the list, including archives, are available at
+http://lists.twibble.org/mailman/listinfo/dc395x/
+
+Parameters
+----------
+The driver uses the settings from the EEPROM set in the SCSI BIOS 
+setup. If there is no EEPROM, the driver uses default values.
+Both can be overriden by command line parameters (module or kernel
+parameters).
+
+The syntax is as follows:
+ dc395x = AdapterID, SpeedIdx, DevMode, AdaptMode, Tags, DelayReset
+
+AdapterID : Host Adapter SCSI ID
+SpeedIdx  : 0,1,...7 = 20,13.3,10,8,6.7,5.8,5,4 MHz               [ 7]
+DevMode   : Bitmap for Dev Cfg                                    [63]
+AdaptMode : Bitmap for Adapter Cfg                                [47]
+Tags      : The number of tags is 1<<x, if x has been specified   [ 4]
+DelayReset: The seconds to not accept commands after a SCSI Reset [ 1]
+
+DevMode bit definition:
+   Bit Val(hex) Val(dec)  Meaning
+   *0	 0x01	    1	  Parity check
+   *1	 0x02	    2	  Synchronous Negotiation
+   *2	 0x04	    4	  Disconnection
+   *3	 0x08	    8	  Send Start command on startup. (Not used)
+   *4	 0x10	   16	  Tagged Command Queueing
+   *5	 0x20	   32	  Wide Negotiation
+
+AdaptMode bit definition
+   Bit Val(hex) Val(dec)  Meaning
+   *0	 0x01	    1	  Support more than two drives. (Not used)
+   *1	 0x02	    2	  Use DOS compatible mapping for HDs greater than 1GB.
+   *2	 0x04	    4	  Reset SCSI Bus on startup.
+   *3	 0x08	    8	  Active Negation: Improves SCSI Bus noise immunity.
+    4	 0x10	   16	  Immediate return on BIOS seek command. (Not used)
+ (*)5	 0x20	   32	  Check for LUNs >= 1.
+
+If you set AdapterID to -1, the adapter will use conservative
+("safe") default settings instead; more precisely, dc395x=-1 is a
+shortcut for dc395x=7,4,9,15,2,10
+
+If you specify -2 for a value, it will be ignored. You don't need to
+specify all six parameters.

 Hotplug initialization model
 ============================
 In this model a LLD controls when SCSI hosts are introduced and removed
 from the SCSI subsystem. Hosts can be introduced as early as driver
 initialization and removed as late as driver shutdown. Typically a driver
-will respond to a sysfs probe() callback that indicates a HBA is present
-(e.g. a PCI device). After confirming it is a device that it wants to
-control, it will initialize the HBA and then register a new host with the

+detected. After confirming that the new device is one that the LLD wants
+to control, the LLD will initialize the HBA and then register a new host
+with the SCSI mid level.
 
 Hot unplugging a HBA that controls a disk which is processing SCSI
 commands on a mounted file system is an ugly situation. Issues with
 this scenario are still being worked through. The primary concern is
 the stability of the kernel (specifically the block and SCSI subsystems)
 since the effected disk can be "cleaned up" the next time it is seen.
+In the sysfs model, a remove() callback indicates a HBA has disappeared.
 
 During LLD initialization the driver should register itself with the
 appropriate IO bus on which it expects to find HBA(s) (e.g. the PCI bus).
 This can probably be done via sysfs. Any driver parameters (especially
-those that are writeable after the driver is loaded) could also be
-registered with sysfs at this point. At the end of driver initialization
-the SCSI mid level is typically not aware of its presence.

 is a typical sequence of calls between the LLD and the mid level.

 is initialized. The functions below are listed alphabetically and their
 names all start with "scsi_".
 
+Summary:
+   scsi_add_device - creates new scsi device (lu) instance
+   scsi_add_host - perform sysfs registration and SCSI bus scan.
+   scsi_add_timer - (re-)start timer on a SCSI command.

+   scsi_assign_lock - replace default host_lock with given lock
+   scsi_bios_ptable - return copy of block device's partition table
+   scsi_block_requests - prevent further commands being queued to given host
+   scsi_delete_timer - cancel timer on a SCSI command.
+   scsi_partsize - parse partition table into cylinders, heads + sectors
+   scsi_register - create and register a scsi host adapter instance.
+   scsi_register_host - register a low level host driver
+   scsi_remove_device - detach and remove a SCSI device
+   scsi_remove_host - detach and remove all SCSI devices owned by host
+   scsi_report_bus_reset - report scsi _bus_ reset observed
+   scsi_set_device - place device reference in host structure

 	  To use your PC-cards, you will need supporting software from David
 	  Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
 	  for location).  Please also read the PCMCIA-HOWTO, available from
-	  <http://www.linuxdoc.org/docs.html#howto>.

 	  This driver is also available as a module ( = code which can be
 	  inserted in and removed from the running kernel whenever you want).

- *
- * Version : v1.18 (Oct 11, 2001)
- *
- * Description: Linux device driver for LSI Logic MegaRAID controller
- *
- * Supported controllers: MegaRAID 418, 428, 438, 466, 762, 467, 471, 490
- *                                      493.
- * History:
- *
- * Version 0.90:
- *     Original source contributed by Dell; integrated it into the kernel and
- *     cleaned up some things.  Added support for 438/466 controllers.
- * Version 0.91:
- *     Aligned mailbox area on 16-byte boundary.
- *     Added schedule() at the end to properly clean up.
- *     Made improvements for conformity to linux driver standards.
- *
- * Version 0.92:
- *     Added support for 2.1 kernels.
- *         Reads from pci_dev struct, so it's not dependent on pcibios.
- *         Added some missing virt_to_bus() translations.
- *     Added support for SMP.
- *         Changed global cli()'s to spinlocks for 2.1, and simulated
- *          spinlocks for 2.0.
- *     Removed setting of SA_INTERRUPT flag when requesting Irq.
- *
- * Version 0.92ac:
- *     Small changes to the comments/formatting. Plus a couple of
- *      added notes. Returned to the authors. No actual code changes
- *      save printk levels.
- *     8 Oct 98        Alan Cox <alan.cox@linux.org>
- *
- *     Merged with 2.1.131 source tree.
- *     12 Dec 98       K. Baranowski <kgb@knm.org.pl>
- *
- * Version 0.93:
- *     Added support for vendor specific ioctl commands (M_RD_IOCTL_CMD+xxh)
- *     Changed some fields in MEGARAID struct to better values.
- *     Added signature check for Rp controllers under 2.0 kernels
- *     Changed busy-wait loop to be time-based
- *     Fixed SMP race condition in isr
- *     Added kfree (sgList) on release
- *     Added #include linux/version.h to megaraid.h for hosts.h
- *     Changed max_id to represent max logical drives instead of targets.
- *
- * Version 0.94:
- *     Got rid of some excess locking/unlocking
- *     Fixed slight memory corruption problem while memcpy'ing into mailbox
- *     Changed logical drives to be reported as luns rather than targets
- *     Changed max_id to 16 since it is now max targets/chan again.
- *     Improved ioctl interface for upcoming megamgr
- *
- * Version 0.95:
- *     Fixed problem of queueing multiple commands to adapter;
- *       still has some strange problems on some setups, so still
- *       defaults to single.  To enable parallel commands change
- *       #define MULTI_IO in megaraid.h
- *     Changed kmalloc allocation to be done in beginning.
- *     Got rid of C++ style comments
- *
- * Version 0.96:
- *     762 fully supported.
- *
- * Version 0.97:
- *     Changed megaraid_command to use wait_queue.
- *
- * Version 1.00:
- *     Checks to see if an irq occurred while in isr, and runs through
- *       routine again.
- *     Copies mailbox to temp area before processing in isr
- *     Added barrier() in busy wait to fix volatility bug
- *     Uses separate list for freed Scbs, keeps track of cmd state
- *     Put spinlocks around entire queue function for now...
- *     Full multi-io commands working stablely without previous problems
- *     Added skipXX LILO option for Madrona motherboard support
- *
- * Version 1.01:
- *     Fixed bug in mega_cmd_done() for megamgr control commands,
- *       the host_byte in the result code from the scsi request to
- *       scsi midlayer is set to DID_BAD_TARGET when adapter's
- *       returned codes are 0xF0 and 0xF4.
- *
- * Version 1.02:
- *     Fixed the tape drive bug by extending the adapter timeout value
- *       for passthrough command to 60 seconds in mega_build_cmd().
- *
- * Version 1.03:
- *    Fixed Madrona support.
- *    Changed the adapter timeout value from 60 sec in 1.02 to 10 min
- *      for bigger and slower tape drive.
- *    Added driver version printout at driver loadup time
- *
- * Version 1.04
- *    Added code for 40 ld FW support.
- *    Added new ioctl command 0x81 to support NEW_READ/WRITE_CONFIG with
- *      data area greater than 4 KB, which is the upper bound for data
- *      tranfer through scsi_ioctl interface.
- *    The additional 32 bit field for 64bit address in the newly defined
- *      mailbox64 structure is set to 0 at this point.
- *
- * Version 1.05
- *    Changed the queing implementation for handling SCBs and completed
- *      commands.
- *    Added spinlocks in the interrupt service routine to enable the driver
- *      function in the SMP environment.
- *    Fixed the problem of unnecessary aborts in the abort entry point, which
- *      also enables the driver to handle large amount of I/O requests for
- *      long duration of time.
- * Version 1.06
- *              Intel Release
- * Version 1.07
- *    Removed the usage of uaccess.h file for kernel versions less than
- *    2.0.36, as this file is not present in those versions.
- *
- * Version 108
- *    Modified mega_ioctl so that 40LD megamanager would run
- *    Made some changes for 2.3.XX compilation , esp wait structures
- *    Code merge between 1.05 and 1.06 .
- *    Bug fixed problem with ioctl interface for concurrency between
- *    8ld and 40ld firwmare
- *    Removed the flawed semaphore logic for handling new config command
- *    Added support for building own scatter / gather list for big user
- *    mode buffers

+ * Version : v2.00.3 (Feb 19, 2003) - Atul Mukker <Atul.Mukker@lsil.com>
  *
- * BUGS:
- *     Some older 2.1 kernels (eg. 2.1.90) have a bug in pci.c that
- *     fails to detect the controller as a pci device on the system.
+ * Description: Linux device driver for LSI Logic MegaRAID controller
  *
- *     Timeout period for upper scsi layer, i.e. SD_TIMEOUT in
- *     /drivers/scsi/sd.c, is too short for this controller. SD_TIMEOUT
- *     value must be increased to (30 * HZ) otherwise false timeouts
- *     will occur in the upper layer.
+ * Supported controllers: MegaRAID 418, 428, 438, 466, 762, 467, 471, 490, 493
+ *					518, 520, 531, 532
  *
- *     Never set skip_id. The existing PCI code the megaraid uses fails
- *     to properly check the vendor subid in some cases. Setting this then
- *     makes it steal other i960's and crashes some boxes
+ * This driver is supported by LSI Logic, with assistance from Red Hat, Dell,
+ * and others. Please send updates to the public mailing list
+ * linux-megaraid-devel@dell.com, and subscribe to and read archives of this
+ * list at http://lists.us.dell.com/.
  *
- *     Far too many ifdefs for versions.
+ * For history of changes, see ChangeLog.megaraid.

- * Description:
- *     Determine what INQUIRY pages are supported by @sdev, and try the
- *     different pages until we get an identifier, or no other pages are
- *     left. Start with page 0x83 (device id) and then try page 0x80
- *     (serial number). If neither of these pages gets an id, use the

- *
- *     The first character of sdev_driverfs_dev.name is SCSI_UID_SER_NUM
- *     (S) if we used page 0x80, SCSI_UID_UNKNOWN (Z) if we used the
- *     default name, otherwise it starts with the page 0x83 id type
- *     (see the SCSI Primary Commands specification for details).
- *
- * Notes:
- *     If a device returns the same serial number for different LUNs or
- *     even for different LUNs on different devices, special handling must
- *     be added to get an id, or a new black list flag must be added (so
- *     we use the default name, or add a way to prefix the id/name with
- *     SCSI_UID_UNKNOWN - and change the define to something meaningful
- *     like SCSI_UID_NOT_UNIQUE). Complete user level scanning would be

- * Cache handling for 32-bit ARM processors.
+ *	MM Cache Management
+ *	===================
+ *
+ *	The arch/arm/mm/cache-*.S and arch/arm/mm/proc-*.S files
+ *	implement these methods.
+ *
+ *	Start addresses are inclusive and end addresses are exclusive;
+ *	start addresses should be rounded down, end addresses up.
+ *
+ *	See linux/Documentation/cachetlb.txt for more information.
+ *	Please note that the implementation of these, and the required
+ *	effects are cache-type (VIVT/VIPT/PIPT) specific.
+ *
+ *	flush_cache_kern_all()
+ *
+ *		Unconditionally clean and invalidate the entire cache.
+ *
+ *	flush_cache_user_mm(mm)
+ *
+ *		Clean and invalidate all user space cache entries
+ *		before a change of page tables.
  *
- * Note that on ARM, we have a more accurate specification than that
- * Linux's "flush".  We therefore do not use "flush" here, but instead
- * use:
+ *	flush_cache_user_range(start, end, flags)
  *
- * clean:      the act of pushing dirty cache entries out to memory.
- * invalidate: the act of discarding data held within the cache,
- *             whether it is dirty or not.
+ *		Clean and invalidate a range of cache entries in the
+ *		specified address space before a change of page tables.
+ *		- start - user start address (inclusive, page aligned)
+ *		- end   - user end address   (exclusive, page aligned)
+ *		- flags - vma->vm_flags field
+ *
+ *	coherent_kern_range(start, end)
+ *
+ *		Ensure coherency between the Icache and the Dcache in the
+ *		region described by start, end.  If you have non-snooping
+ *		Harvard caches, you need to implement this function.
+ *		- start  - virtual start address
+ *		- end    - virtual end address
+ *
+ *	DMA Cache Coherency
+ *	===================
+ *
+ *	dma_inv_range(start, end)
+ *
+ *		Invalidate (discard) the specified virtual address range.
+ *		May not write back any entries.  If 'start' or 'end'
+ *		are not cache line aligned, those lines must be written
+ *		back.
+ *		- start  - virtual start address
+ *		- end    - virtual end address
+ *
+ *	dma_clean_range(start, end)
+ *
+ *		Clean (write back) the specified virtual address range.
+ *		- start  - virtual start address
+ *		- end    - virtual end address
+ *
+ *	dma_flush_range(start, end)
+ *
+ *		Clean and invalidate the specified virtual address range.
+ *		- start  - virtual start address

- * Add a page to the dirty page list.

- * It is a sad fact of life that this function is called from several places

- *
- * If the page has buffers, the uptodate buffers are set dirty, to preserve
- * dirty-state coherency between the page and the buffers.  It the page does
- * not have buffers then when they are later attached they will all be set
- * dirty.
- *
- * The buffers are dirtied before the page is dirtied.  There's a small race
- * window in which a writepage caller may see the page cleanness but not the
- * buffer dirtiness.  That's fine.  If this code were to set the page dirty
- * before the buffers, a concurrent writepage caller could clear the page dirty
- * bit, see a bunch of clean buffers and we'd end up with dirty buffers/clean
- * page on the dirty page list.
- *
- * There is also a small window where the page is dirty, and not on dirty_pages.
- * Also a possibility that by the time the page is added to dirty_pages, it has
- * been set clean.  The page lists are somewhat approximate in this regard.
- * It's better to have clean pages accidentally attached to dirty_pages than to
- * leave dirty pages attached to clean_pages.
- *
- * We use private_lock to lock against try_to_free_buffers while using the
- * page's buffer list.  Also use this to protect against clean buffers being
- * added to the page after it was set dirty.
- *
- * FIXME: may need to call ->reservepage here as well.  That's rather up to the
- * address_space though.
