perf tools: Fix compatibility with libelf 0.8 and autodetect

2009-10-25T16:09:14Z

The Makefile now automatically defines LIBELF_NO_MMAP when libelf 0.8.x is detected. libelf 0.8 is still maintained and some distributions such as Arch Linux use it instead of elfutils.

perf timechart: Improve the visual appearance of scheduler delays

2009-10-20T01:39:21Z

[from KS feedback] Currently, scheduler delays are shown in a mostly transparent, light yellow color. This color is rather hard to see on several screens, especially projectors. This patch changes the color of the scheduler delays to be a much more "hard" yellow that survived the kernel summit projector.

We released the first version of perf with 0.0.1 in v2.6.31, time to double our version number to 0.0.2 ;-) Cc: Peter Zijlstra Cc: Mike Galbraith Cc: Paul Mackerras Cc: Arnaldo Carvalho de Melo Cc: Frederic Weisbecker LKML-Reference: Signed-off-by: Ingo Molnar

perf tools: Remove static debugfs path from parse-events

2009-10-12T20:41:05Z

Timechart doesn't work if debugfs is not in /sys/kernel/debug/. Fixed by using global debugfs_path which is filled in by perf. Signed-off-by: Ashwin Chaugule Cc: "Arjan van de Ven" LKML-Reference: Signed-off-by: Ingo Molnar

perf tools: Fix const char type propagation

2009-10-12T06:35:00Z

The following perf build warnings/errors in function argument types: builtin-sched.c:1894: warning: passing argument 1 of 'sort_dimension__add' discards qualifiers from pointer target type util/trace-event-parse.c:685: warning: passing argument 2 of 'read_expected' discards qualifiers from pointer target type util/trace-event-parse.c:741: warning: passing argument 4 of 'test_type_token' discards qualifiers from pointer target type util/trace-event-parse.c:706: warning: passing argument 2 of 'read_expected_item' discards qualifiers from pointer target type ... trigger because older GCC is not able to prove that sort_dimension__add() does not change the string. Some goes for test_type_token(). Fix this by improving type consistency.

perf tools: elf_sym__is_function() should accept "zero" sized functions

2009-10-06T10:08:08Z

Asm routines that end up having size equal to zero are not really zero sized, and as now we do kernel_maps__fixup_sym_end, at least for kernel routines this gets fixed. A similar fixup needs to be done for the userspace bits as well, but as this fixup started only because in /proc/kallsyms we don't have the end address nor the function size, it appeared here first.

perf timechart: Add a power-only mode

2009-10-01T07:26:40Z

For doing work on the Linux power management components, I need to make long (30+ seconds) traces. Currently, this then results in a HUGE svg file, with mostly process data that isn't interesting. This patch adds a --power-only mode to perf timechart that only outputs the CPU power section of the SVG; this significantly reduces the size of the SVG file, making even 30+ second traces viewable with inkscape. As a minor tweak for the same effect, the minimum text size is decreased; current inkscape cannot zoom in deep enough to show text this small, but it reduces inkscape compute time.
