We use the fixmap for accessing pci config space in pci_mmcfg_read/write(). The problem is in pci_exp_set_dev_base(). It is caching a last accessed address to avoid calling set_fixmap_nocache() whenever pci_mmcfg_read/write() is used. static inline void pci_exp_set_dev_base(int bus, int devfn) { u32 dev_base = base | (bus << 20) | (devfn << 12); if (dev_base != mmcfg_last_accessed_device) { mmcfg_last_accessed_device = dev_base; set_fixmap_nocache(FIX_PCIE_MCFG, dev_base); } } cpu0 cpu1 --------------------------------------------------------------------------- pci_mmcfg_read("device-A") pci_exp_set_dev_base() set_fixmap_nocache() pci_mmcfg_read("device-B") pci_exp_set_dev_base() set_fixmap_nocache() pci_mmcfg_read("device-B") pci_exp_set_dev_base() /* doesn't flush tlb */ But if cpus accessed the above order, the second pci_mmcfg_read() on cpu0 doesn't flush the TLB, because "mmcfg_last_accessed_device" is device-B. So, second pci_mmcfg_read() on cpu0 accesses a device-A via a previous TLB cache. This problem became the cause of several strange behavior. This patches fixes this situation by adds "mmcfg_last_accessed_cpu" check. [ Alternatively, we could make a per-cpu mapping area or something. Not that it's probably worth it, but if we wanted to avoid all locking and instead just disable preemption, that would be the way to go. --Linus ] Signed-off-by: NOGAWA Hirofumi <hogawa@miraclelinux.com> Signed-off-by: NOGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

When this code was converted to use sk_for_each() the logic for the "best hash chain length" code was reversed, breaking everything. The original code was of the form: size = 0; do { if (++size >= best_size_so_far) goto next; } while ((sk = sk->next) != NULL); best_size_so_far = size; best = result; next:; and this got converted into: sk_for_each(sk2, node, head) if (++size < best_size_so_far) { best_size_so_far = size; best = result; } Which does something very very different from the original.

While looking at DCCP sequence numbers, I stumbled over a problem with the following definition of before in tcp.h: static inline int before(__u32 seq1, __u32 seq2) { return (__s32)(seq1-seq2) < 0; } Problem: This definition suffers from an an ambiguity, i.e. always before(a, (a + 2^31) % 2^32)) = 1 before((a + 2^31) % 2^32), a) = 1 In text: when the difference between a and b amounts to 2^31, a is always considered `before' b, the function can not decide. The reason is that implicitly 0 is `before' 1 ... 2^31-1 ... 2^31 Solution: There is a simple fix, by defining before in such a way that 0 is no longer `before' 2^31, i.e. 0 `before' 1 ... 2^31-1 By not using the middle between 0 and 2^32, before can be made unambiguous. This is achieved by testing whether seq2-seq1 > 0 (using signed 32-bit arithmetic). I attach a patch to codify this. Also the `after' relation is basically a redefinition of `before', it is now defined as a macro after before. Signed-off-by: NGerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: NDavid S.

compile.h is created super-late in the build. But proc_misc.c want to include it, and it's generally not sane to have a header file in include/linux be created at the end of the build: it's either not present or, worse, wrong for most of the build. So the patch arranges for compile.h to be built at the start of the build process. It also consolidates the compile.h rules with those for version.h and utsname.h, so they all get built together.

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# / _-----=> irqs-off | / _----=> need-resched || / _---=> hardirq/softirq ||| / _--=> preempt-depth |||| / ||||| delay cmd pid ||||| time | caller \ / ||||| \ | / IRQ_19-1479 1D..1 0us : __trace_start_sched_wakeup (try_to_wake_up) IRQ_19-1479 1D..1 0us : __trace_start_sched_wakeup <<...>-5856> (37 0) IRQ_19-1479 1D..1 0us : __trace_start_sched_wakeup (c01262ba 0 0) IRQ_19-1479 1D..1 0us : resched_task (try_to_wake_up) IRQ_19-1479 1D..1 0us : __spin_unlock_irqrestore (try_to_wake_up) ... <idle>-0 1...1 11us!: default_idle (cpu_idle) ... <idle>-0 0Dn.1 602us : smp_apic_timer_interrupt (c0103baf 1 0) ... <...>-5856 0D..2 618us : __switch_to (__schedule) <...>-5856 0D..2 618us : __schedule <<idle>-0> (20 162) <...>-5856 0D..2 619us : __spin_unlock_irq (__schedule) <...>-5856 0...1 619us : trace_stop_sched_switched (__schedule) <...>-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 495ab9c0 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.

In the current jbd code, if a buffer on BJ_SyncData list is dirty and not locked, the buffer is refiled to BJ_Locked list, submitted to the IO and waited for IO completion. But the fsstress test showed the case that when a buffer was already submitted to the IO just before the buffer_dirty(bh) check, the buffer was not waited for IO completion. Following patch solves this problem. If it is assumed that a buffer is submitted to the IO before the buffer_dirty(bh) check and still being written to disk, this buffer is refiled to BJ_Locked list.

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.

The PDA patches introduced a bug in ptrace: it reads eflags from the wrong place on the target's stack, but writes it back to the correct place. The result is a corrupted eflags, which is most visible when it turns interrupts off unexpectedly. This patch fixes this by making the ptrace code a little less fragile. It changes [gs]et_stack_long to take a straightforward byte offset into struct pt_regs, rather than requiring all callers to do a sizeof(struct pt_regs) offset adjustment. This means that the eflag's offset (EFL_OFFSET) on the target stack can be simply computed with offsetof().

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).
