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 tools: Move pr_* debug macros into debug object

2014-07-17T15:58:39+00:00

Moving pr_* debug macros to have it with in same object as debug
variables, becase we will change them to use verbose variable in next
patch.

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 kvm: Introduce HAVE_KVM_STAT_SUPPORT flag

2014-07-07T19:55:23+00:00

kvm stat support is currently conditional on i386/x86_64. Let's abstract
this into a HAVE_KVM_STAT_SUPPORT flag, so that other architectures can
support kvm stat as well.

Previous commit 'perf x86: Fix perf to use non-executable stack, again'
moved stack map into MAP__VARIABLE map type again. Fixing the dwarf
unwind test stack map lookup appropriately.
