2011-01-07amd64_edac: Allocate driver instances dynamicallyBorislav Petkov

2011-01-06kernel-doc: code reorganizationRandy Dunlap
Move 'main' code vs. subroutines around so that they are not so intermixed, for better readability/understanding (relative to Perl). It was messy to follow the primary flow of code execution with the code being mixed. Now the code begins with data initialization, followed by all subroutines, then ends with the main code execution. This is almost totally source code movement, with a few changes as needed for forward declarations.

2011-01-05perf tools: Fix perf_event.h header usageStephane Eranian
This patch fixes the usage of the perf_event.h header file between command modules and the supporting code in util. It is necessary to ensure that ALL files use the SAME perf_event.h header from the kernel source tree. There were a couple of #include <linux/perf_event.h> mixed with #include "../../perf_event.h". This caused issues on some distros because of mismatch in the layout of struct perf_event_attr. That eventually led perf stat to segfault. Cc: David S.

2011-01-05x86: Avoid calling arch_trigger_all_cpu_backtrace() at the same timeDongdong Deng
The spin_lock_debug/rcu_cpu_stall detector uses trigger_all_cpu_backtrace() to dump cpu backtrace. Therefore it is possible that trigger_all_cpu_backtrace() could be called at the same time on different CPUs, which triggers and 'unknown reason NMI' warning. The following case illustrates the problem: CPU1 CPU2 ... CPU N trigger_all_cpu_backtrace() set "backtrace_mask" to cpu mask | generate NMI interrupts generate NMI interrupts ... \ | / \ | / The "backtrace_mask" will be cleaned by the first NMI interrupt at nmi_watchdog_tick(), then the following NMI interrupts generated by other cpus's arch_trigger_all_cpu_backtrace() will be taken as unknown reason NMI interrupts. This patch uses a test_and_set to avoid the problem, and stop the arch_trigger_all_cpu_backtrace() from calling to avoid dumping a double cpu backtrace info when there is already a trigger_all_cpu_backtrace() in progress.

2011-01-05sched: Change wait_for_completion_*_timeout() to return a signed longNeilBrown
wait_for_completion_*_timeout() can return: 0: if the wait timed out -ve: if the wait was interrupted +ve: if the completion was completed. As they currently return an 'unsigned long', the last two cases are not easily distinguished which can easily result in buggy code, as is the case for the recently added wait_for_completion_interruptible_timeout() call in net/sunrpc/cache.c So change them both to return 'long'. As MAX_SCHEDULE_TIMEOUT is LONG_MAX, a large +ve return value should never overflow. Signed-off-by: NeilBrown <neilb@suse.de> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: J.

Jean Pihet has a patch integrated into the generic layer (kernel/power/suspend.c) which will make use of it. the type= field got removed from both, it was never used and the type is differed by the event type itself. perf timechart userspace tool gets adjusted in a separate patch.

2011-01-04perf test: Add test for counting open syscallsArnaldo Carvalho de Melo
To test the use of the perf_evsel class on something other than the tools from where we refactored code to create it. It calls open() N times and then checks if the event created to monitor it returns N events. [acme@felicio linux]$ perf test 1: vmlinux symtab matches kallsyms: Ok 2: detect open syscall event: Ok [acme@felicio linux]$ It does.

2011-01-04perf evsel: Auto allocate resources needed for some methodsArnaldo Carvalho de Melo
While writing the first user of the routines created from the ad-hoc routines in the existing builtins I noticed that the resulting set of calls was too long, reduce it by doing some best effort allocations. Tools that need to operate on multiple threads and cpus should pre-allocate enough resources by explicitely calling the perf_evsel__alloc_{fd,counters} methods.

2011-01-04perf tools: Refactor all_tids to hold nr and the mapArnaldo Carvalho de Melo
So that later, we can pass the thread_map instance instead of (thread_num, thread_map) for things like perf_evsel__open and friends, just like was done with cpu_map.

2011-01-04perf evsel: Introduce per cpu and per thread open helpersArnaldo Carvalho de Melo
Abstracting away the loops needed to create the various event fd handlers. The users have to pass a confiruged perf->evsel.attr field, which is already usable after perf_evsel__new (constructor) time, using defaults. Comes out of the ad-hoc routines in builtin-stat, that now uses it. Fixed a small silly bug where we were die()ing before killing our children, dysfunctional family this one 8-) Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Cc: Tom Zanussi <tzanussi@gmail.com> LKML-Reference: <new-submission> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
