| * | | | | perf tools: replace mkostemp with mkstempIrina Tirdea2012-09-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mkostemp function is only available in glibc. This leads to compile error in Android, since bionic is derived from BSD. Replacing mkostemp with mkstemp. mkstemp is available on both glibc and bionic.

This leads to a compile error. Including termios.h fixes the compilation error since it defines struct winsize.

| * | | | | perf tools: include basename for non-glibc systemsIrina Tirdea2012-09-07

The glibc version of basename is better than the POSIX version since it does not modify its argument. Android has only one version of basename which is defined in libgen.h. This version is the same as the glibc version. Error on Android: util/annotate.c: In function 'symbol__annotate_printf': util/annotate.c:503:3: error: implicit declaration of function 'basename' [-Werror=implicit-function-declaration] util/annotate.c:503:3: error: nested extern declaration of 'basename' [-Werror=nested-externs] util/annotate.c:503:14: error: assignment makes pointer from integer without a cast [-Werror] On Android libgen.h should be included to define basename.

| * | | | | perf tools: Add pmu mappings to header informationRobert Richter2012-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With dynamic pmu allocation there are also dynamically assigned pmu ids. These ids are used in event->attr.type to describe the pmu to be used for that event. The information is available in sysfs, e.g: /sys/bus/event_source/devices/breakpoint/type: 5 /sys/bus/event_source/devices/cpu/type: 4 /sys/bus/event_source/devices/ibs_fetch/type: 6 /sys/bus/event_source/devices/ibs_op/type: 7 /sys/bus/event_source/devices/software/type: 1 /sys/bus/event_source/devices/tracepoint/type: 2 These mappings are needed to know which samples belong to which pmu. If a pmu is added dynamically like for ibs_fetch or ibs_op the type value may vary. Now, when decoding samples from perf.data this information in sysfs might be no longer available or may have changed. We need to store it in perf.data. Using the header for this. Now the header information created with perf report contains an additional section looking like this: # pmu mappings: ibs_op = 7, ibs_fetch = 6, cpu = 4, breakpoint = 5, tracepoint = 2, software = 1 Signed-off-by: Robert Richter <robert.richter@amd.com> Acked-by: Peter Zijlstra <peterz@infradead.org> Cc: Ingo Molnar <mingo@kernel.org> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/1345144224-27280-9-git-send-email-robert.richter@amd.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

This way we get unique events names that also support pmu event syntax (<pmu_name>/<config>/<modifier>). No need to reconstruct the name anymore from its attributes. We use the event_desc of the header to store the name in the perf.data header. Thus it is also available for perf report. Implemented by putting the parser in different states to parse events or configs. And since event names are now generated from the command line specification. Update event names in test cases accordingly.

However, this is currently added to the end of the path, behind /usr/include/slang and /usr/include/gtk-2.0 if use of the respective libraries is enabled. Thus the '#include "../perf.h"' in util/parse-events.l can actually include /usr/include/perf.h if it exists. Move '-Iutil/' ahead of all the other preprocessor options.
