perf util: Make util its own library

2024-06-26T18:07:42Z

Make the util directory into its own library. This is done to avoid compiling code twice, once for the perf tool and once for the perf python module. For convenience: arch/common.c scripts/perl/Perf-Trace-Util/Context.c scripts/python/Perf-Trace-Util/Context.c are made part of this library.

perf tests arm64: Compile tests unconditionally

2019-06-17T18:57:16Z

In order to subsequently add more tests for the arm64 architecture we compile the tests target for arm64 systematically. Further explanation provided by Mark Rutland: Given prior questions regarding this commit, it's probably worth spelling things out more explicitly, e.g. Currently we only build the arm64/tests directory if CONFIG_DWARF_UNWIND is selected, which is fine as the only test we have is arm64/tests/dwarf-unwind.o. So that we can add more tests to the test directory, let's unconditionally build the directory, but conditionally build dwarf-unwind.o depending on CONFIG_DWARF_UNWIND. There should be no functional change as a result of this patch.

perf tools: Rename build libperf to perf

2019-02-14T18:18:08Z

Rename build libperf to perf, because it's used to build perf. The libperf build object name will be used for libperf library.

perf tools: Add ARM64 perf_regs_load to support libunwind and enable testing

2015-05-29T15:43:40Z

Newest libunwind does support ARM64, and perf is able to utilize it also. This patch enables the perf test dwarf unwind for arm64.

perf build: Add arch x86 objects building

2015-02-12T16:12:01Z

Move the x86 arch objects building under build framework to be included in the libperf build object. Adding also arch/$(ARCH)/Build files for the rest of the archs. The reason for this is that in arch/Build we now do: +libperf-y += $(ARCH)/ which would make the build to fail on other architectures, because the build framework requires 'Build' file in nested directories and this patch adds it only for x86.
