perf report: Accept fifos as input file The default input file for perf report is not handled the same way as perf record does it for its output file. This leads to unexpected behavior of perf report, etc. E.g.: # perf record -a -e cpu-cycles sleep 2 | perf report | cat failed to open perf.data: No such file or directory (try 'perf record' first) While perf record writes to a fifo, perf report expects perf.data to be read. This patch changes this to accept fifos as input file. Applies to the following commands: perf annotate perf buildid-list perf evlist perf kmem perf lock perf report perf sched perf script perf timechart Also fixes char const* -> const char* type declaration for filename strings. v2: * Prevent potential null pointer access to input_name in builtin-report.c. Needed due to removal of patch "perf report: Setup browser if stdout is a pipe" Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/r/1323248577-11268-5-git-send-email-robert.richter@amd.com Signed-off-by: Robert Richter <robert.richter@amd.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

perf symbols: Add symfs option for off-box analysis using specified tree The symfs argument allows analysis of perf.data file using a locally accessible filesystem tree with debug symbols - e.g., tree created during image builds, sshfs mount, loop mounted KVM disk images, USB keys, initrds, etc. Anything with an OS tree can be analyzed from anywhere without the need to populate a local data store with build-ids. Commiter notes: o Fixed up symfs="/" variants handling. o prefixed DSO__ORIG_GUEST_KMODULE case with symfs too, avoiding use of files outside the symfs directory.

perf timechart: Add a process filter During the Kernel Summit demo of perf/ftrace/timechart, there was a feature request to have a process filter for timechart so that you can zoom into one or a few processes that you are really interested in. This patch adds basic support for this feature, the -p (--process) option now can select a PID or a process name to be shown. Multiple -p options are allowed, and the combined set will be included in the output.

perf timechart: Add a power-only mode 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.

perf util: Make the timechart SVG width dynamic This patch adds a command line option for timechart that allows the user to specify the width of the SVG file. This patch also makes sure that each second of recording has at least 200 units (pixels at 96 DPI) of width. This impacts recordings longer than 5 seconds; recordings shorter than 5 second will scale up to have a width of 1000 units for the whole recording (as before).
