* libperf: Move to tools/lib/perfJiri Olsa2020-01-061-188/+0
| | | | | | | | | | | | | | | | | Move libperf from its current location under tools/perf to a separate directory under tools/lib/. Also change various paths (mainly includes) to reflect the libperf move to a separate directory and add a new directory under MANIFEST.

| | | | | | | | | | | | | | | | | Both static and dynamic tests needs to link with libapi.a, because it's using its functions. Also include path for libapi includes.

* libperf: Fix arch include pathsJiri Olsa2019-08-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Guenter Roeck reported problem with compilation when the ARCH is specified: $ make ARCH=x86_64 In file included from tools/include/asm/atomic.h:6:0, from include/linux/atomic.h:5, from tools/include/linux/refcount.h:41, from cpumap.c:4: tools/include/asm/../../arch/x86/include/asm/atomic.h:11:10: fatal error: asm/cmpxchg.h: No such file or directory The problem is that we don't use SRCARCH (the sanitized ARCH version) and we don't get the proper include path.
