From 93a4388b765d6588d145a2e94e350cc77fd44756 Mon Sep 17 00:00:00 2001 From: Shuah Khan Date: Tue, 14 Apr 2020 15:22:08 -0600 Subject: selftests: add build/cross-build dependency check script Add build/cross-build dependency check script kselftest_deps.sh This script does the following: Usage: ./kselftest_deps.sh -[p] [test_name] kselftest_deps.sh [-p] gcc kselftest_deps.sh [-p] gcc vm kselftest_deps.sh [-p] aarch64-linux-gnu-gcc kselftest_deps.sh [-p] aarch64-linux-gnu-gcc vm - Should be run in selftests directory in the kernel repo. - Checks if Kselftests can be built/cross-built on a system. - Parses all test/sub-test Makefile to find library dependencies. - Runs compile test on a trivial C file with LDLIBS specified in the test Makefiles to identify missing library dependencies. - Prints suggested target list for a system filtering out tests failed the build dependency check from the TARGETS in Selftests the main Makefile when optional -p is specified. - Prints pass/fail dependency check for each tests/sub-test. - Prints pass/fail targets and libraries. - Default: runs dependency checks on all tests. - Optional test name can be specified to check dependencies for it. To make LDLIBS parsing easier - change gpio and memfd Makefiles to use the same temporary variable used to find and add libraries to LDLIBS. - simlify LDLIBS append logic in intel_pstate/Makefile.
