perf: fail if src path does not exist
A missing src directory from a broken kernel recipe resulted only in a warning: WARNING: copyfile: stat of /home/builder/src/tmp-glibc/work-shared/target/kernel-source/tools/arch failed ([Errno 2] No such file or directory: '/home/builder/src/tmp-glibc/work-shared/target/kernel-source/tools/arch') and the build failed horribly. With this change it's an error which can not be missed: ERROR: perf-1.0-r9 do_configure: Path does not exist: /home/builder/src/tmp-glibc/work-shared/target/kernel-source/tools/arch. Maybe PERF_SRC does not match the kernel version. ERROR: perf-1.0-r9 do_configure: Function failed: copy_perf_source_from_kernel ERROR: Logfile of failure stored in: /home/builder/src/tmp-glibc/work/target-linux/perf/1.0-r9/temp/log.do_configure.21083 NOTE: recipe perf-1.0-r9: task do_configure: Failed ERROR: Task (/home/builder/src/poky/meta/recipes-kernel/perf/ failed with exit code '1' To get get perf compiling from a custom kernel, a perf.bbappend can be created which defines PERF_SRC as list of files and directories needed from kernel source tree to compile perf. This varies between kernel versions. Signed-off-by: Mikko Rapeli <> Signed-off-by: Richard Purdie <>
