The e1000 driver has a workaround for 82544 on PCI-X where if the
terminating byte of a buffer is at addresses 0-3 mod 8, then 4 bytes
are shaved off it and defered to a new segment. This is due to an
erratum that could otherwise cause TX hangs.
Unfortunately this breaks TSO because it may cause the TCP header to
be split over two segments which itself causes TX hangs. The solution
is to pull 4 bytes of data up from the next segment rather than pushing
4 bytes off. This ensures the TCP header remains in one piece and
works around the PCI-X hang.
This patch is based on one from Jesse Brandeburg.
This bug has been trigered by both CONFIG_DEBUG_SLAB as well as Xen.
Note that the only reason we don't see this normally is because the
TCP stack starts writing from the end, i.e., it writes the TCP header
first then slaps on the IP header, etc. So the end of the TCP header
(skb->tail - 1 here) is always aligned correctly.
Had we made the start of the IP header (e.g., IPv6) 8-byte aligned
instead, this would happen for normal TCP traffic as well.

Currently after an interface up, the link state is detected 2 seconds later
when the first watchdog timer runs. This patch changes that by triggering
the hardware to generate a link-change interrupt from the up() function
instead. This has the result that the link state gets detected immediately
and without races. This has the potential to speed up booting since a normal
distribution boot process waits for a link before DHCP is attempted.

Fernando Lopez-Lezcano reported frequent scheduling latencies and audio
xruns starting at the 2.6.18-rt kernel, and those problems persisted all
until current -rt kernels. The latencies were serious and unjustified by
system load, often in the milliseconds range.
After a patient and heroic multi-month effort of Fernando, where he
tested dozens of kernels, tried various configs, boot options,
test-patches of mine and provided latency traces of those incidents, the
following 'smoking gun' trace was captured by him:
_------=> CPU#

|| / _---=> hardirq/softirq
||| / _--=> preempt-depth

<...>-5856 0D..1 619us : trace_stop_sched_switched <<...>-5856> (37 0)
what is visible in this trace is that CPU#1 ran try_to_wake_up() for
PID:5856, it placed PID:5856 on CPU#0's runqueue and ran resched_task()
for CPU#0. But it decided to not send an IPI that no CPU - due to
TS_POLLING. But CPU#0 never woke up after its NEED_RESCHED bit was set,
and only rescheduled to PID:5856 upon the next lapic timer IRQ. The
result was a 600+ usecs latency and a missed wakeup!
the bug turned out to be an idle-wakeup bug introduced into the mainline
kernel this summer via an optimization in the x86_64 tree:
commit 495ab9c045
Author: Andi Kleen <ak@suse.de>
Date: Mon Jun 26 13:59:11 2006 +0200
[PATCH] i386/x86-64/ia64: Move polling flag into thread_info_status
During some profiling I noticed that default_idle causes a lot of
memory traffic. I think that is caused by the atomic operations
to clear/set the polling flag in thread_info. There is actually
no reason to make this atomic - only the idle thread does it
to itself, other CPUs only read it. So I moved it into ti->status.
the problem is this type of change:
if (!hlt_counter && boot_cpu_data.hlt_works_ok) {
- clear_thread_flag(TIF_POLLING_NRFLAG);
+ current_thread_info()->status &= ~TS_POLLING;
smp_mb__after_clear_bit();
while (!need_resched()) {
local_irq_disable();
this changes clear_thread_flag() to an explicit clearing of TS_POLLING.
clear_thread_flag() is defined as:
clear_bit(flag, &ti->flags);
and clear_bit() is a LOCK-ed atomic instruction on all x86 platforms:
static inline void clear_bit(int nr, volatile unsigned long * addr)
{
__asm__ __volatile__( LOCK_PREFIX
"btrl %1,%0"
hence smp_mb__after_clear_bit() is defined as a simple compile barrier:
#define smp_mb__after_clear_bit() barrier()
but the explicit TS_POLLING clearing introduced by the patch:
+ current_thread_info()->status &= ~TS_POLLING;
is not an atomic op! So the clearing of the TS_POLLING bit is freely
reorderable with the reading of the NEED_RESCHED bit - and both now
reside in different memory addresses.
CPU idle wakeup very much depends on ordered memory ops, the clearing of
the TS_POLLING flag must always be done before we test need_resched()
and hit the idle instruction(s). [Symmetrically, the wakeup code needs
to set NEED_RESCHED before it tests the TS_POLLING flag, so memory
ordering is paramount.]
Fernando's dual-core Athlon64 system has a sufficiently advanced memory
ordering model so that it triggered this scenario very often.
( And it also turned out that the reason why these latencies never
triggered on my testsystems is that i routinely use idle=poll, which
was the only idle variant not affected by this bug. )
The fix is to change the smp_mb__after_clear_bit() to an smp_mb(), to
act as an absolute barrier between the TS_POLLING write and the
NEED_RESCHED read. This affects almost all idling methods (default,
ACPI, APM), on all 3 x86 architectures: i386, x86_64, ia64.

Linus sayeth:
Google knows everything, and finds, on MS own site no less:
"Windows 2000 default resources:
One 4K memory window
One 2 MB memory window
Two 256-byte I/O windows"
which is clearly utterly bogus and insufficient. But Microsoft apparently
realized this, and:
"Windows XP default resources:
Because one memory window of 4K and one window of 2 MB are not
sufficient for CardBus controllers in many configurations, Windows XP
allocates larger memory windows to CardBus controllers where possible.
However, resource windows are static (that is, the operating system
does not dynamically allocate larger memory windows if new devices
appear.) Under Windows XP, CardBus controllers will be assigned the
following resources:
One 4K memory window, as in Windows 2000
64 MB memory, if that amount of memory is available. If 64 MB is not
available the controller will receive 32 MB; if 32 MB is not available,
the controller will receive 16 MB; if 16 MB is not available, the
bridge will receive 8 MB; and so on down to a minimum assignment of 1
MB in configurations where memory is too constrained for the operating
system to provide a larger window.
Two 256-byte I/O windows"
So I think we have our answer. Windows uses one 4k window, and one 64MB
window. And they are no more dynamic than we are (we _could_ try to do it
dynamically, but let's face it, it's fairly painful to dynamically expand
PCI bus resources - you may need to reprogram everything up to the root,
so it would be absolutely crazy to do that unless you have some serious
masochistic tendencies).
So let's just increase our default value to 64M too.

This fixes some bugs in the gxt4500 framebuffer driver, and adds support
for GXT6000P cards.
First, I had the red and blue channels swapped in the colormap update code,
resulting in penguins' noses and feet turning blue (though the penguins
weren't actually shivering :).
Secondly, the code that calculated the values to put in the PLL that
generates the pixel clock wasn't observing some constraints that I wasn't
originally aware of, but am now that I have some documentation on the chip.
The GXT6000P is essentially identical from software's point of view, except
for a different reference clock for the PLL, and the addition of a geometry
engine (which this driver doesn't use).

Fix a bug that only appears when AoE goes over a network card that does not
support scatter-gather. The headers in the linear part of the skb appeared
to be larger than they really were, resulting in data that was offset by 24
bytes.
This patch eliminates the offset data on cards that don't support
scatter-gather or have had scatter-gather turned off. There remains an
unrelated issue that I'll address in a separate email.

libata depended on SCSI command to have the correct length when
tranlating it into an ATA command. This generally worked for commands
issued by SCSI HLD but user could issue arbitrary broken command using
sg interface.
Also, when building ATAPI command, full command size was always
copied. Because some ATAPI devices needs bytes after CDB cleared, if
upper layer doesn't clear bytes after CDB, such devices will
malfunction. This necessiated recent clear-garbage-after-CDB fix in
sg interfaces. However, scsi_execute() isn't fixed yet and HL-DT-ST
DVD-RAM GSA-H30N malfunctions on initialization commands issued from
SCSI.
This patch makes xlat functions always consider SCSI cmd_len. Each
translation function checks for proper cmd_len and ATAPI translaation
clears bytes after CDB.

Variable names in xlat functions are quite confusing now. 'scsicmd'
is used for CDB while qc->scsicmd points to struct scsi_cmnd while
'cmd' is used for struct scsi_cmnd.
This patch cleans up variable names in xlat functions such that 'scmd'
is used for struct scsi_cmnd and 'cdb' for CDB. Also, 'scmd' local
variable is added if qc->scsicmd is used multiple times.

Since commit 368c73d4f6 the kernel will try
to update the non-writeable BAR registers 0..3 of PIIX4 IDE adapters if
pci_assign_unassigned_resources() is used to do full resource assignment of
the bus. This fails because in the PIIX4 these BAR registers have
implicitly assumed values and read back as zero; it used to work because
the kernel used to just write zero to that register the read back value did
match what was written.
The fix is a new resource flag IORESOURCE_PCI_FIXED used to mark a resource
as non-movable. This will also be useful to keep other import system
resources from being moved around - for example system consoles on PCI
busses.
