c3921ab | Linus Torvalds | 11 May 2008, 23:04:48 UTC | Add new 'cond_resched_bkl()' helper function It acts exactly like a regular 'cond_resched()', but will not get optimized away when CONFIG_PREEMPT is set. Normal kernel code is already preemptable in the presense of CONFIG_PREEMPT, so cond_resched() is optimized away (see commit 02b67cc3ba36bdba351d6c3a00593f4ec550d9d3 "sched: do not do cond_resched() when CONFIG_PREEMPT"). But when wanting to conditionally reschedule while holding a lock, you need to use "cond_sched_lock(lock)", and the new function is the BKL equivalent of that. Also make fs/locks.c use it.

28e6103 | David S. Miller | 11 May 2008, 09:07:19 UTC | sparc: Fix debugger syscall restart interactions. So, forever, we've had this ptrace_signal_deliver implementation which tries to handle all of the nasties that can occur when the debugger looks at a process about to take a signal. It's meant to address all of these issues inside of the kernel so that the debugger need not be mindful of such things. Problem is, this doesn't work. The idea was that we should do the syscall restart business first, so that the debugger captures that state. Otherwise, if the debugger for example saves the child's state, makes the child execute something else, then restores the saved state, we won't handle the syscall restart properly because we lose the "we're in a syscall" state. The code here worked for most cases, but if the debugger actually passes the signal through to the child unaltered, it's possible that we would do a syscall restart when we shouldn't have. In particular this breaks the case of debugging a process under a gdb which is being debugged by yet another gdb. gdb uses sigsuspend to wait for SIGCHLD of the inferior, but if gdb itself is being debugged by a top-level gdb we get a ptrace_stop(). The top-level gdb does a PTRACE_CONT with SIGCHLD to let the inferior gdb see the signal. But ptrace_signal_deliver() assumed the debugger would cancel out the signal and therefore did a syscall restart, because the return error was ERESTARTNOHAND. Fix this by simply making ptrace_signal_deliver() a nop, and providing a way for the debugger to control system call restarting properly: 1) Report a "in syscall" software bit in regs->{tstate,psr}. It is set early on in trap entry to a system call and is fully visible to the debugger via ptrace() and regsets. 2) Test this bit right before doing a syscall restart. We have to do a final recheck right after get_signal_to_deliver() in case the debugger cleared the bit during ptrace_stop(). 3) Clear the bit in trap return so we don't accidently try to set that bit in the real register. As a result we also get a ptrace_{is,clear}_syscall() for sparc32 just like sparc64 has. M68K has this same exact bug, and is now the only other user of the ptrace_signal_deliver hook. It needs to be fixed in the same exact way as sparc. Signed-off-by: David S. Miller <davem@davemloft.net> | 11 May 2008, 09:07:19 UTC |
986bef8 | David S. Miller | 11 May 2008, 04:11:23 UTC | sparc: Fix ptrace() detach. Forever we had a PTRACE_SUNOS_DETACH which was unconditionally recognized, regardless of the personality of the process. Unfortunately, this value is what ended up in the GLIBC sys/ptrace.h header file on sparc as PTRACE_DETACH and PT_DETACH. So continue to recognize this old value. Luckily, it doesn't conflict with anything we actually care about. Signed-off-by: David S. Miller <davem@davemloft.net> | 11 May 2008, 08:59:05 UTC |

8e3e076 | Linus Torvalds | 11 May 2008, 03:58:02 UTC | BKL: revert back to the old spinlock implementation The generic semaphore rewrite had a huge performance regression on AIM7 (and potentially other BKL-heavy benchmarks) because the generic semaphores had been rewritten to be simple to understand and fair. The latter, in particular, turns a semaphore-based BKL implementation into a mess of scheduling. The attempt to fix the performance regression failed miserably (see the previous commit 00b41ec2611dc98f87f30753ee00a53db648d662 'Revert "semaphore: fix"'), and so for now the simple and sane approach is to instead just go back to the old spinlock-based BKL implementation that never had any issues like this. This patch also has the advantage of being reported to fix the regression completely according to Yanmin Zhang, unlike the semaphore hack which still left a couple percentage point regression. As a spinlock, the BKL obviously has the potential to be a latency issue, but it's not really any different from any other spinlock in that respect. We do want to get rid of the BKL asap, but that has been the plan for several years. These days, the biggest users are in the tty layer (open/release in particular) and Alan holds out some hope: "tty release is probably a few months away from getting cured - I'm afraid it will almost certainly be the very last user of the BKL in tty to get fixed as it depends on everything else being sanely locked." so while we're not there yet, we do have a plan of action.

Quoth Sven Wegener: "I'm currently investigating a regression that has showed up with my last git pull yesterday. Bisecting the commits showed bf726e "semaphore: fix" to be the culprit, reverting it fixed the issue. Symptoms: During heavy filesystem usage (e.g. a kernel compile) I get several compiler processes in uninterruptible sleep, blocking all i/o on the filesystem. System is an Intel Core 2 Quad running a 64bit kernel and userspace. Filesystem is xfs on top of lvm. See below for the output of sysrq-w." See http://lkml.org/lkml/2008/5/10/45 for full report. In the meantime, we can just fix the BKL performance regression by reverting back to the good old BKL spinlock implementation instead, since any sleeping lock will generally perform badly, especially if it tries to be fair.

A lot of stuff in spitz/akita/etc. depends on corgi_ssp to be initialised early. However corgi_ssp initialisation fails, because at that time pxa*-ssp devices don't have drivers.

Looking at the workload i found and fixed what i believe to be the real bug causing the AIM7 regression: it was inefficient wakeup / scheduling / locking behavior of the new generic semaphore code, causing suboptimal performance. The problem comes from the following code. The new semaphore code does this on down(): spin_lock_irqsave(&sem->lock, flags); if (likely(sem->count > 0)) sem->count--; else __down(sem); spin_unlock_irqrestore(&sem->lock, flags); and this on up(): spin_lock_irqsave(&sem->lock, flags); if (likely(list_empty(&sem->wait_list))) sem->count++; else __up(sem); spin_unlock_irqrestore(&sem->lock, flags); where __up() does: list_del(&waiter->list); waiter->up = 1; wake_up_process(waiter->task); and where __down() does this in essence: list_add_tail(&waiter.list, &sem->wait_list); waiter.task = task; waiter.up = 0; for (;;) { [...] spin_unlock_irq(&sem->lock); timeout = schedule_timeout(timeout); spin_lock_irq(&sem->lock); if (waiter.up) return 0; } the fastpath looks good and obvious, but note the following property of the contended path: if there's a task on the ->wait_list, the up() of the current owner will "pass over" ownership to that waiting task, in a wake-one manner, via the waiter->up flag and by removing the waiter from the wait list. That is all and fine in principle, but as implemented in kernel/semaphore.c it also creates a nasty, hidden source of contention! The contention comes from the following property of the new semaphore code: the new owner owns the semaphore exclusively, even if it is not running yet. So if the old owner, even if just a few instructions later, does a down() [lock_kernel()] again, it will be blocked and will have to wait on the new owner to eventually be scheduled (possibly on another CPU)! Or if another task gets to lock_kernel() sooner than the "new owner" scheduled, it will be blocked unnecessarily and for a very long time when there are 2000 tasks running. I.e. the implementation of the new semaphores code does wake-one and lock ownership in a very restrictive way - it does not allow opportunistic re-locking of the lock at all and keeps the scheduler from picking task order intelligently. This kind of scheduling, with 2000 AIM7 processes running, creates awful cross-scheduling between those 2000 tasks, causes reduced parallelism, a throttled runqueue length and a lot of idle time. With increasing number of CPUs it causes an exponentially worse behavior in AIM7, as the chance for a newly woken new-owner task to actually run anytime soon is less and less likely. Note that it takes just a tiny bit of contention for the 'new-semaphore catastrophy' to happen: the wakeup latencies get added to whatever small contention there is, and quickly snowball out of control! I believe Yanmin's findings and numbers support this analysis too. The best fix for this problem is to use the same scheduling logic that the kernel/mutex.c code uses: keep the wake-one behavior (that is OK and wanted because we do not want to over-schedule), but also allow opportunistic locking of the lock even if a wakee is already "in flight". The patch below implements this new logic. With this patch applied the AIM7 regression is largely fixed on my quad testbox: # v2.6.25 vanilla: .................. Tasks Jobs/Min JTI Real CPU Jobs/sec/task 2000 56096.4 91 207.5 789.7 0.4675 2000 55894.4 94 208.2 792.7 0.4658 # v2.6.26-rc1-166-gc0a1811 vanilla: ...................................

We are now back to within 1% of the v2.6.25 performance levels and have zero idle time during the test, as expected. Btw., interactivity also improved dramatically with the fix - for example console-switching became almost instantaneous during this workload (which after all is running 2000 tasks at once!), without the patch it was stuck for a minute at times. There's another nice side-effect of this speedup patch, the new generic semaphore code got even smaller: text data bss dec hex filename 1241 0 0 1241 4d9 semaphore.o.before 1207 0 0 1207 4b7 semaphore.o.after (because the waiter.up complication got removed.) Longer-term we should look into using the mutex code for the generic semaphore code as well - but i's not easy due to legacies and it's outside of the scope of v2.6.26 and outside the scope of this patch as well.

Its moved to addon_cpuid_features.c as this file is shared between 32 and 64 bit.

Change the boot CPU check so it works on Voyager somewhere in the future as well :) Also panic, when a secondary has PAT disabled but the primary one has alrady switched to PAT. We have no way to undo that. The white list is kept for now to ensure that we can rely on known to work CPU types and concentrate on the software induced problems instead of fighthing CPU erratas and subtle wreckage caused by not yet verified CPUs.
