2016-03-24	perf tests: Fix tarpkg build test error output redirection	Arnaldo Carvalho de Melo	1	-1/+1
	So we need to trow away just stdout, leaving stderr to be caught by the build tests infrastructure, so that we can see what went wrong when the tarpkg build test fails: $ make -C tools/perf build-test make: Entering directory '/home/acme/git/linux/tools/perf' - tarpkg: ./tests/perf-targz-src-pkg . tests/make:302: recipe for target 'tarpkg' failed make[1]: * [tarpkg] Error 2 Makefile:102: recipe for target 'build-test' failed make: * [build-test] Error 2 make: Leaving directory '/home/acme/git/linux/tools/perf' $ cat tools/perf/tarpkg ./tests/perf-targz-src-pkg . PERF_VERSION = 4.5.g05f5ec PERF_VERSION = 4.5.g05f5ec In file included from bench/mem-memcpy-x86-64-asm.S:9:0: bench/../../../arch/x86/lib/memcpy_64.S:5:29: fatal error: asm/cpufeatures.h: No such file or directory compilation terminated. mv: cannot stat ‘bench/.mem-memcpy-x86-64-asm.o.tmp’: No such file or directory make[5]: * [bench/mem-memcpy-x86-64-asm.o] Error 1 make[5]: * Waiting for unfinished jobs.... make[4]: * [bench] Error 2 make[4]: * Waiting for unfinished jobs.... make[3]: * [perf-in.o] Error 2 make[3]: * Waiting for unfinished jobs.... make[2]: *** [all] Error 2 $ So the test flow is: 1. Run: 'make -C tools/perf build-test' 2. One of its tests failed, in this case, the 'tarpkg' one 3. Look at what went wrong, by looking at the output of that test, in tools/perf/tarpkg Admittedly, this should be shortcircuited to showing what went wrong directly from the 'make build-test' step, but lets first fix this tarpkg one and the problem it spotted, which should be fixed by adding some extra file to the tools/perf/MANIFEST so that detached tarballs continue being self contained and build successfully.

2014-01-13	perf tools: Add test for building detached source tarballs	Arnaldo Carvalho de Melo	1	-0/+21
	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.
