selftests/powerpc: Fix build failure in ebb tests

2020-06-30T19:36:12Z

[ Upstream commit 896066aa0685af3434637998b76218c2045142a8 ] We use OUTPUT directory as TMPOUT for checking no-pie option. Since commit f2f02ebd8f38 ("kbuild: improve cc-option to clean up all temporary files") when building powerpc/ from selftests directory, the OUTPUT directory points to powerpc/pmu/ebb/ and gets removed when checking for -no-pie option in try-run routine, subsequently build fails with the following: $ make -C powerpc ... TARGET=ebb; BUILD_TARGET=$OUTPUT/$TARGET; mkdir -p $BUILD_TARGET; make OUTPUT=$BUILD_TARGET -k -C $TARGET all make[2]: Entering directory '/home/linux-master/tools/testing/selftests/powerpc/pmu/ebb' make[2]: *** No rule to make target 'Makefile'. make[2]: Failed to remake makefile 'Makefile'. make[2]: *** No rule to make target 'ebb.c', needed by '/home/linux-master/tools/testing/selftests/powerpc/pmu/ebb/reg_access_test'. make[2]: *** No rule to make target 'ebb_handler.S', needed by '/home/linux-master/tools/testing/selftests/powerpc/pmu/ebb/reg_access_test'. make[2]: *** No rule to make target 'trace.c', needed by '/home/linux-master/tools/testing/selftests/powerpc/pmu/ebb/reg_access_test'. make[2]: *** No rule to make target 'busy_loop.S', needed by '/home/linux-master/tools/testing/selftests/powerpc/pmu/ebb/reg_access_test'. make[2]: Target 'all' not remade because of errors. Fix this by adding a suffix to the OUTPUT directory so that the failure is avoided.

Pull powerpc updates from Michael Ellerman: "Slightly late as I had to rebase mid-week to insert a bug fix: - A large series from Nick for 64-bit to further rework our exception vectors, and rewrite portions of the syscall entry/exit and interrupt return in C. The result is much easier to follow code that is also faster in general. - Cleanup of our ptrace code to split various parts out that had become badly intertwined with #ifdefs over the years. - Changes to our NUMA setup under the PowerVM hypervisor which should hopefully avoid non-sensical topologies which can lead to warnings from the workqueue code and other problems. - MAINTAINERS updates to remove some of our old orphan entries and update the status of others. - Quite a few other small changes and fixes all over the map.

selftests/powerpc: Fix try-run when source tree is not writable

2020-04-01T03:30:50Z

We added a usage of try-run to pmu/ebb/Makefile to detect if the toolchain supported the -no-pie option. This fails if we build out-of-tree and the source tree is not writable, as try-run tries to write its temporary files to the current directory. That leads to the -no-pie option being silently dropped, which leads to broken executables with some toolchains. If we remove the redirect to /dev/null in try-run, we see the error: make[3]: Entering directory '/linux/tools/testing/selftests/powerpc/pmu/ebb' /usr/bin/ld: cannot open output file .54.tmp: Read-only file system collect2: error: ld returned 1 exit status make[3]: Nothing to be done for 'all'. And looking with strace we see it's trying to use a file that's in the source tree: lstat("/linux/tools/testing/selftests/powerpc/pmu/ebb/.54.tmp", 0x7ffffc0f83c8) We can fix it by setting TMPOUT to point to the $(OUTPUT) directory, and we can verify with strace it's now trying to write to the output directory: lstat("/output/kselftest/powerpc/pmu/ebb/.54.tmp", 0x7fffd1bf6bf8) And also see that the -no-pie option is now correctly detected.

selftests/powerpc: Fix Makefiles for headers_install change

2018-09-28T05:07:45Z

Commit b2d35fa5fc80 ("selftests: add headers_install to lib.mk") introduced a requirement that Makefiles more than one level below the selftests directory need to define top_srcdir, but it didn't update any of the powerpc Makefiles. This broke building all the powerpc selftests with eg: make[1]: Entering directory '/src/linux/tools/testing/selftests/powerpc' BUILD_TARGET=/src/linux/tools/testing/selftests/powerpc/alignment; mkdir -p $BUILD_TARGET; make OUTPUT=$BUILD_TARGET -k -C alignment all make[2]: Entering directory '/src/linux/tools/testing/selftests/powerpc/alignment' ../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory make[2]: *** No rule to make target '../../../../scripts/subarch.include'. make[2]: Failed to remake makefile '../../../../scripts/subarch.include'. Makefile:38: recipe for target 'alignment' failed Fix it by setting top_srcdir in the affected Makefiles.
