| * | alpha: Change do_timer() to xtime_update()Torben Hohn2011-01-31
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | xtime_update() takes the xtime_lock itself. timer_interrupt() is only called on the boot cpu. See do_entInt(). So "state" in timer_interrupt does not require protection by xtime_lock.

Syscalls of statfs family (native, compat and foreign - osf and hpux on alpha and parisc resp.) switched to those. Removes some boilerplate code, simplifies cleanup on errors...

| | | | | | | | | | | | | | | | | | | | | | The perf hardware pmu got initialized at various points in the boot, some before early_initcall() some after (notably arch_initcall). The problem is that the NMI lockup detector is ran from early_initcall() and expects the hardware pmu to be present. Sanitize this by moving all architecture hardware pmu implementations to initialize at early_initcall() and move the lockup detector to an explicit initcall right after that.

* alpha: use single HAE window on T2 core logic (gamma, sable)Ivan Kokshaysky2010-10-26
| | | | | | | | | | | | | | | | | | | T2 are the only alpha SMP systems that do HAE switching at runtime, which is fundamentally racy on SMP. This patch limits MMIO space on T2 to HAE0 only, like we did on MCPCIA (rawhide) long ago. This leaves us with only 112 Mb of PCI MMIO (128 Mb HAE aperture minus 16 Mb reserved for EISA), but since linux PCI allocations are reasonably tight, it should be enough for sane hardware configurations. Also, fix a typo in MCPCIA_FROB_MMIO macro which shouldn't call set_hae() if MCPCIA_ONE_HAE_WINDOW is defined. It's more for correctness, as set_hae() is a no-op anyway in that case.

* irq_work: Add generic hardirq context callbacksPeter Zijlstra2010-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide a mechanism that allows running code in IRQ context. It is most useful for NMI code that needs to interact with the rest of the system -- like wakeup a task to drain buffers. Perf currently has such a mechanism, so extract that and provide it as a generic feature, independent of perf so that others may also benefit. The IRQ context callback is generated through self-IPIs where possible, or on architectures like powerpc the decrementer (the built-in timer facility) is set to generate an interrupt immediately. Architectures that don't have anything like this get to do with a callback from the timer tick. These architectures can call irq_work_run() at the tail of any IRQ handlers that might enqueue such work (like the perf IRQ handler) to avoid undue latencies in processing the work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want interrupts disabled on all paths leading to RESTORE_ALL; otherwise, we are risking an IRQ coming between the updates of alpha_mv->hae_cache and *alpha_mv->hae_register and set_hae() within the IRQ getting badly confused. RESTORE_ALL used to play with disabling IRQ itself, but that got removed back in 2002, without making sure we had them disabled on all paths. It's cheaper to make sure we have them disabled than to revert to original variant...

| * alpha: deal with multiple simultaneously pending signalsAl Viro2010-09-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unlike the other targets, alpha sets _one_ sigframe and buggers off until the next syscall/interrupt, even if more signals are pending. It leads to quite a few unpleasant inconsistencies, starting with SIGSEGV potentially arriving not where it should and including e.g. mess with sigsuspend(); consider two pending signals blocked until sigsuspend() unblocks them. We pick the first one; then, if we are hit by interrupt while in the handler, we process the second one as well. If we are not, and if no syscalls had been made, we get out of the first handler and leave the second signal pending; normally sigreturn() would've picked it anyway, but here it starts with restoring the original mask and voila - the second signal is blocked again. On everything else we get both delivered consistently. It's actually easy to fix; the only thing to watch out for is prevention of double syscall restart. Fortunately, the idea I've nicked from arm fix by rmk works just fine... Testcase demonstrating the behaviour in question; on alpha we get one or both flags set (usually one), on everything else both are always set. #include <signal.h> #include <stdio.h> int had1, had2; void f1(int sig) { had1 = 1; } void f2(int sig) { had2 = 1; } main() { sigset_t set1, set2; sigemptyset(&set1); sigemptyset(&set2); sigaddset(&set2, 1); sigaddset(&set2, 2); signal(1, f1); signal(2, f2); sigprocmask(SIG_SETMASK, &set2, NULL); raise(1); raise(2); sigsuspend(&set1); printf("had1:%d had2:%d\n", had1, had2); } Tested-by: Michael Cree <mcree@orcon.net.nz> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Matt Turner <mattst88@gmail.com>
| * alpha: fix a 14 years old bug in sigreturn tracingAl Viro2010-09-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The way sigreturn() is implemented on alpha breaks PTRACE_SYSCALL, all way back to 1.3.95 when alpha has grown PTRACE_SYSCALL support. What happens is direct return to ret_from_syscall, in order to bypass mangling of a3 (error indicator) and prevent other mutilations of registers (e.g. by syscall restart). That's fine, but... the entire TIF_SYSCALL_TRACE codepath is kept separate on alpha and post-syscall stopping/notifying the tracer is after the syscall. And the normal path we are forcibly switching to doesn't have it. So we end up with *one* stop in traced sigreturn() vs. two in other syscalls. And yes, strace is visibly broken by that; try to strace the following #include <signal.h> #include <stdio.h> void f(int sig) {} main() { signal(SIGHUP, f); raise(SIGHUP); write(1, "eeeek\n", 6); } and watch the show. The close(1) = 405 in the end of strace output is coming from return value of write() (6 == __NR_close on alpha) and syscall number of exit_group() (__NR_exit_group == 405 there). The fix is fairly simple - the only thing we end up missing is the call of syscall_trace() and we can tell whether we'd been called from the SYSCALL_TRACE path by checking ra value. Since we are setting the switch_stack up (that's what sys_sigreturn() does), we have the right environment for calling syscall_trace() - just before we call undo_switch_stack() and return. Since undo_switch_stack() will overwrite s0 anyway, we can use it to store the result of "has it been called from SYSCALL_TRACE path?" check. The same thing applies in rt_sigreturn().

Leaving that after switch to ERESTARTNOHAND was a Bad Idea(tm), since now that screws the restart - if we hit the case when get_signal_to_deliver() returns 0, we will step back to syscall insn, with v0 set to EINTR and a3 to 1. The latter won't matter, since EINTR is 4, aka __NR_write. Testcase: #include <signal.h> #define _GNU_SOURCE #include <unistd.h> #include <sys/syscall.h> main() { sigset_t mask; sigemptyset(&mask); sigaddset(&mask, SIGCONT); sigprocmask(SIG_SETMASK, &mask, NULL); kill(0, SIGCONT); syscall(__NR_sigsuspend, 1, "b0rken\n", 7); } results on alpha in immediate message to stdout... Fix is obvious; moreover, since we don't need regs anymore, we can switch to normal prototypes for these guys and lose the wrappers. Even better, rt_sigsuspend() is identical to generic version in kernel/signal.c now.
