selftests: kselftest_deps: Use "grep -E" instead of "egrep"

2022-11-25T17:55:52Z

The latest version of grep claims the egrep is now obsolete so the build now contains warnings that look like: egrep: warning: egrep is obsolescent; using grep -E fix this up by moving the related file to use "grep -E" instead. sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/testing/selftests` Here are the steps to install the latest grep: wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz tar xf grep-3.8.tar.gz cd grep-3.8 && ./configure && make sudo make install export PATH=/usr/local/bin:$PATH Signed-off-by: Tiezhu Yang Signed-off-by: Shuah Khan

selftests: add build/cross-build dependency check script

2020-04-23T23:23:20Z

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.
