perf tools: Fix build breakage on arm64 targets

2014-10-01T17:44:17+00:00

Attempting to build the perf tool for an arm64 target results in the following failure: arch/arm64/util/unwind-libunwind.c: In function 'libunwind__arch_reg_id': arch/arm64/util/unwind-libunwind.c:77:3: error: implicit declaration of function 'pr_err' pr_err("unwind: invalid reg id %d\n", regnum); ^ arch/arm64/util/unwind-libunwind.c:77:3: error: nested extern declaration of 'pr_err' This is due to commit 84f5d36f4866 ("perf tools: Move pr_* debug macros into debug object") moving the pr_* macros into a new header file, but failing to update architectures other than x86. This patch adds the missing include, and fixes the build again.

perf tools powerpc: Fix build issue when DWARF support is disabled

2014-09-17T20:08:07+00:00

The powerpc skip callchain code uses DWARF, so we must disable it if DWARF is disabled.

perf tools powerpc: Explicitly include util/debug.h

2014-08-20T11:29:10+00:00

Looks like util/debug.h was indirectly included before and is no longer included now. pr_debug is left undefined and the build of perf tool fails on Powerpc. Explicitly include util/debug.h.

perf powerpc: Include util/util.h and remove stringify macros

perf tools: Allow TSC conversion on any arch

2014-07-17T15:59:00+00:00

It is possible to record a perf.data file on one architecture and process it on another. Consequently, TSC conversion functions need to be moved out of the arch directory.
