perf build: Specify shellcheck should use bash

2025-06-30T16:43:06Z

When someone has a global shellcheckrc file, for example at ~/.config/shellcheckrc, with the directive 'shell=sh', building perf will fail with many shellcheck errors like: In tests/shell/base_probe/test_adding_kernel.sh line 294: (( TEST_RESULT += $? )) ^---------------------^ SC3006 (warning): In POSIX sh, standalone ((..)) is undefined. For more information: https://www.shellcheck.net/wiki/SC3006 -- In POSIX sh, standalone ((..)) is... make[5]: *** [tests/Build:91: tests/shell/base_probe/test_adding_kernel.sh.shellcheck_log] Error 1 Passing the '-s bash' option ensures that it runs correctly regardless of a developers global configuration. This patch adds '-s bash' and other options to the SHELLCHECK variable in Makefile.perf and makes use of the variable consistently.

perf build: Rename TEST_LOGS to SHELL_TEST_LOGS

2025-03-24T16:38:20Z

Rename TEST_LOGS to SHELL_TEST_LOGS as later changes will add more kinds of test logs. Minor comment tweak in Makefile.perf as more than just test shell tests are checked.

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: Add arch tests

2015-10-05T19:55:38Z

Tests that only make sense for some architectures currently live in the same place as the generic tests. Move out the x86-specific tests into tools/perf/arch/x86/tests and define an 'arch_tests' array, which is the list of tests that only apply to the build architecture. The main idea is to encourage developers to add arch tests to build out perf's test coverage, without dumping everything in tools/perf/tests.

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.
