perf build: Add arch x86 objects building

2015-02-12T16:12:01+00:00

Move the x86 arch objects building under build framework to be included in the libperf build object. Adding also arch/$(ARCH)/Build files for the rest of the archs. The reason for this is that in arch/Build we now do: +libperf-y += $(ARCH)/ which would make the build to fail on other architectures, because the build framework requires 'Build' file in nested directories and this patch adds it only for x86.

perf tools: Allow TSC conversion on any arch

2014-07-17T15:59:00+00:00

It is possible to record a perf.data file on one architecture and process it on another. Consequently, TSC conversion functions need to be moved out of the arch directory.

perf kvm: Add skip_event() for --duration option

2014-07-16T20:57:32+00:00

Current code skips output of the x86 specific HLT event in order to avoid flooding the output with enabled --duration option. The events to be skipped should be architecture dependent, though. Let's add an architecture specific array of events to be skipped and introduce a skip_event() function checking against that array.

perf kvm: Move arch specific code into arch/

2014-07-16T20:57:32+00:00

Parts of a 'perf kvm stat' code make sense only for x86. Let's move this code into the arch/x86/kvm-stat.c file and add util/kvm-stat.h for generic structure definitions. Add a global array 'kvm_reg_events_ops' for accessing the arch-specific 'kvm_events_ops' from generic code. Since the several global arrays (i.e. 'kvm_events_tp') have been moved to arch/*, we can not know their sizes and use them directly in builtin-kvm.c. This patch fixes that problem by adding trimming NULL element to each array and changing the behavior of their handlers in generic code.

perf tools: Add libdw DWARF post unwind support

2014-02-24T12:29:36+00:00

Adding libdw DWARF post unwind support, which is part of elfutils-devel/libdw-dev package from version 0.158. The new code is contained in unwin-libdw.c object, and implements unwind__get_entries unwind interface function. New Makefile variable NO_LIBDW_DWARF_UNWIND was added to control its compilation, and is marked as disabled now. It's factored with the rest of the Makefile unwind build code in the next patch. Arch specific code was added for x86.
