There's multiple reason the counter might be unavailable, change the condition to !->index since perf_event_index() should return 0 for all those cases.

Put the logic to compute the event index into a per pmu method. This is required because the x86 rules are weird and wonderful and don't match the capabilities of the current scheme. AFAIK only powerpc actually has a usable userspace read of the PMCs but I'm not at all sure anybody actually used that. ARM is restored to the default since it currently does not support userspace access at all. And all software events are provided with a method that reports their index as 0 (disabled).

Add event maps for Intel x86 processors (with architected PMU v2 or later). On AMD, there is frequency scaling but no Turbo. There is no core cycle event not subject to frequency scaling, therefore we do not provide a mapping.

This event counts the number of reference core cpu cycles. Reference means that the event increments at a constant rate which is not subject to core CPU frequency adjustments. The event may not count when the processor is in halted (low power) state. As such, it may not be equivalent to wall clock time. However, when the processor is not halted state, the event keeps a constant correlation with wall clock time.

On failure, perf_evlist__mmap_per_{cpu,thread} will try to munmap() every map that doesn't have a NULL base. This will fail with EINVAL if one of them has base == MAP_FAILED, clobbering errno, so that perf_evlist__map will return EINVAL on any failure regardless of the root cause.

The problem is that when SAMPLE_PERIOD is not set, the kernel generates a number of samples in proportion to an event's period. Number of these samples may be too big and the kernel throttles all samples above a defined limit. E.g.: I want to trace when a process sleeps. I created a process which sleeps for 1ms and for 4ms. perf got 100 events in both cases. swapper 0 [000] 1141.371830: sched_stat_sleep: comm=foo pid=1801 delay=1386750 [ns] swapper 0 [000] 1141.369444: sched_stat_sleep: comm=foo pid=1801 delay=4499585 [ns] In the first case a kernel want to send 4499585 events and in the second case it wants to send 1386750 events. perf-reports shows that process sleeps in both places equal time. Instead of this we can get only one sample with an attribute period. As result we have less data transferring between kernel and user-space and we avoid throttling of samples. The patch "events: Don't divide events if it has field period" added a kernel part of this functionality.

This adds a default setting for semaphores parameter, and enables semaphores by default on IVB. For now, as semaphores interaction with VTd causes random issues on SNB, we do not enable them by default. But they can still be enabled via the semaphores=1 kernel parameter. v2: enables semaphores on SNB when IO remapping is disabled, with base on Keith Packard patch.

This prevents an in-kernel division by zero which happens when we are asking for i915_chipset_val too quickly, or within a race condition between the power monitoring thread and userspace accesses via debugfs. The issue can be reproduced easily via the following command: while ``; do cat /sys/kernel/debug/dri/0/i915_emon_status; done This is particularly dangerous because it can be triggered by a non-privileged user by just reading the debugfs entry.
