The flex and bison tools generate arch-independent C code so its binaries are not prefixed with the target-arch prefix. With this patch the Linux 3.4-rc2 can be successfuly build on OE-Core.

Currently the parsers objects (bison/flex related) are each time perf is built. No matter the generated files are already in place, the parser generation is executed every time. Changing the rules to have proper flex/bison objects generation dependencies. The parsers code is not rebuilt until the flex/bison source files are touched. Also when flex/bison source is changed, only dependent objects are rebuilt.

In case the user specified NO_GTK2 on the make cmdline, compilation would fail with undefined symbol because the Makefile would not set the correct cpp variable: NO_GTK2 vs. NO_GTK2_SUPPORT. This patch renames the variable to the correct name.

This patch adds a simple GTK2-based browser to 'perf report' that's based on the TTY-based browser in builtin-report.c. To launch "perf report" using the new GTK interface just type: $ perf report --gtk The interface is somewhat limited in features at the moment: - No callgraph support - No KVM guest profiling support - No color coding for percentages - No sorting from the UI - ..and many, many more! That said, I think this patch a reasonable start to build future features on.

Adding pmu object which provides interface to pmu's sysfs
event format definition located at:
${sysfs_mount}/bus/event_source/devices/${pmu}/format
Following interface is exported:
struct perf_pmu* perf_pmu__find(char *name);
- this function returns pmu object, which is then
passed as a handle to other interface functions
int perf_pmu__config(struct perf_pmu *pmu, struct perf_event_attr *attr,
struct list_head *head_terms);
- this function configures perf_event_attr struct based
on pmu's format definitions and config terms data,
containined in head_terms list.
Parser generator is used to retrive the pmu's format definition.
The generated parser is part of the patch. Added makefile rule
'pmu-parser' to generate the parser code out of the bison/flex
sources.
Added builtin test 'Test perf pmu format parsing', which could
be run like:
perf test pmu
