2014-01-20perf tools: Add support for the xtensa architectureBaruch Siach1-0/+7
Tested using kernel tracepoints on a QEMU simulated environment. Kernel support for perf depends on the patch "xtensa: enable HAVE_PERF_EVENTS", which is scheduled for v3.14. Hardware performance counters are not supported under xtensa yet.

2014-01-20perf timechart: Fix wrong SVG heightStanislav Fomichev1-0/+3
If we call perf timechart with -p 0 arguments, it means we don't want any tasks related data. It works, but space for tasks data is reserved in the generated SVG. Remove this unused empty space via passing 0 as count to the open_svg.

2014-01-17perf tools: Remove unnecessary callchain cursor state restore on unmatchFrederic Weisbecker1-3/+0
If a new callchain branch doesn't match a single entry of the node that it is given against comparison in append_chain(), then the cursor is expected to be at the same position as it was before the comparison loop. As such, there is no need to restore the cursor position on exit in case of non matching branches.

2014-01-17perf callchain: Spare double comparison of callchain first entryFrederic Weisbecker1-10/+10
When a new callchain child branch matches an existing one in the rbtree, the comparison of its first entry is performed twice: 1) From append_chain_children() on branch lookup 2) If 1) reports a match, append_chain() then compares all entries of the new branch against the matching node in the rbtree, and this comparison includes the first entry of the new branch again. Lets shortcut this by performing the whole comparison only from append_chain() which then returns the result of the comparison between the first entry of the new branch and the iterating node in the rbtree. If the first entry matches, the lookup on the current level of siblings stops and propagates to the children of the matching nodes. This results in less comparisons performed by the CPU.

2014-01-16perf tools: Do proper comm override error handlingFrederic Weisbecker3-11/+15
The comm overriding API ignores memory allocation failures by silently keeping the previous and out of date comm. As a result, the user may get buggy events without ever being notified about the problem and its source. Lets start to fix this by propagating the error from the API. Not all callers may be doing proper error handling on comm set yet but this is the first step toward it.

2014-01-15perf: tools: Fix cross buildingMark Rutland3-7/+9
Currently the feature-checks Makefile does not inherit $(CC), and calls cc rather than $(CROSS_COMPILE)gcc. Thus the feature checks invoke the native toolchain rather than the cross toolchain, and can identify features as available when they are not. This can break the build. Additionally the native pkg-config is always called as opposed to $(CROSS_COMPILE)pkg-config, so the wrong flags and paths may be passed to the cross compiler. This patch passes CROSS_COMPILE down to the feature-checks Makefile, and forces its use. Additionally pkg-config is replaced with $(CROSS_COMPILE)pkg-config via a new $(PKG_CONFIG) variable. This patch has been build tested on x86_64 and arm.

Test one of the main kernel Makefile targets to generate a perf sources tarball suitable for build outside the full kernel sources. This is to test that the tools/perf/MANIFEST file lists all the files needed to be in such tarball, which sometimes gets broken when we move files around, like when we made some files that were in tools/perf/ available to other tools/ codebases by moving it to tools/include/, etc. Now everytime we use 'make -C tools/perf -f tests/make' this test will be performed, helping detect such problems earlier in the devel cycle.
