      selftest/powerpc: Fix false failures for skipped tests · a6d8a215
      由 Sachin Sant 提交于 
      Tests under alignment subdirectory are skipped when executed on previous
generation hardware, but harness still marks them as failed.

  test: test_copy_unaligned
  tags: git_version:unknown
  [SKIP] Test skipped on line 26
  skip: test_copy_unaligned
  selftests: copy_unaligned [FAIL]

The MAGIC_SKIP_RETURN_VALUE value assigned to rc variable is retained till
the program exit which causes the test to be marked as failed.

This patch resets the value before returning to the main() routine.
With this patch the test o/p is as follows:

  test: test_copy_unaligned
  tags: git_version:unknown
  [SKIP] Test skipped on line 26
  skip: test_copy_unaligned
  selftests: copy_unaligned [PASS]

      selftests: lib.mk Fix individual test builds · e53aff45
      由 Shuah Khan 提交于 
      In commit a8ba798b ("selftests: enable O and KBUILD_OUTPUT"), added
support to generate compile targets in a user specified directory. OUTPUT
variable controls the location which is undefined when tests are built in
the test directory or with "make -C tools/testing/selftests/x86".

make -C tools/testing/selftests/x86/
make: Entering directory '/lkml/linux_4.11/tools/testing/selftests/x86'
Makefile:44: warning: overriding recipe for target 'clean'
../lib.mk:51: warning: ignoring old recipe for target 'clean'
gcc -m64 -o /single_step_syscall_64 -O2 -g -std=gnu99 -pthread -Wall  single_step_syscall.c -lrt -ldl
/usr/bin/ld: cannot open output file /single_step_syscall_64: Permission denied
collect2: error: ld returned 1 exit status
Makefile:50: recipe for target '/single_step_syscall_64' failed
make: *** [/single_step_syscall_64] Error 1
make: Leaving directory '/lkml/linux_4.11/tools/testing/selftests/x86'

Same failure with "cd tools/testing/selftests/x86/;make" run.

Fix this with a change to lib.mk to define OUTPUT to be the pwd when
MAKELEVEL is 0. This covers both cases mentioned above.

      selftests/powerpc: Fix remaining fallout from recent changes · 68bd42d9
      由 Michael Ellerman 提交于 
      In benchmarks we need to use $(TEST_GEN_PROGS) after we include lib.mk,
because lib.mk does the substitution to add $(OUTPUT).

In math the vmx and fpu names were typoed so they no longer matched
correctly, put back the 'v' and 'f'.

In tm we need to substitute $(OUTPUT) into SIGNAL_CONTEXT_CHK_TESTS so
that the rule matches.

In pmu there is an extraneous ':' on the end of $$BUILD_TARGET for the
clean and install rules, which breaks the logic in the child Makefiles.

      selftests: Fix the .S and .S -> .o rules · 634ce97c
      由 Michael Ellerman 提交于 
      Both these rules incorrectly use $< (first prerequisite) rather than
$^ (all prerequisites), meaning they don't work if we're using more than
one .S file as input. Switch them to using $^.

They also don't include $(CPPFLAGS) and other variables used in the
default rules, which breaks targets that require those. Fix that by
using the builtin $(COMPILE.S) and $(LINK.S) rules.

      selftests: Fix the .c linking rule · 2047f1d8
      由 Michael Ellerman 提交于 
      Currently we can't build some tests, for example:

  $ make -C tools/testing/selftests/ TARGETS=vm
  ...
  gcc -Wall -I ../../../../usr/include   -lrt -lpthread ../../../../usr/include/linux/kernel.h userfaultfd.c -o tools/testing/selftests/vm/userfaultfd
  /tmp/ccmOkQSM.o: In function `stress':

  userfaultfd.c:(.text+0xcee): undefined reference to `pthread_create'
  userfaultfd.c:(.text+0xd30): undefined reference to `pthread_create'
  userfaultfd.c:(.text+0xd77): undefined reference to `pthread_join'
  userfaultfd.c:(.text+0xe7d): undefined reference to `pthread_join'

  userfaultfd.c:(.text+0x13e2): undefined reference to `pthread_attr_setstacksize'
  collect2: error: ld returned 1 exit status

This is because the rule for linking .c files to binaries is incorrect.

The first bug is that it uses $< (first prerequisite) instead of $^ (all
preqrequisites), fix it by using ^$.

Secondly the ordering of the prerequisites vs $(LDLIBS) is wrong,
meaning on toolchains that use --as-needed we fail to link (as above).
Fix that by placing $(LDLIBS) *after* ^$.

Finally switch to using the default rule $(LINK.c), so that we get
$(CPPFLAGS) etc. included.

      selftests: Fix selftests build to just build, not run tests · d83c3ba0
      由 Michael Ellerman 提交于 
      In commit 88baa78d ("selftests: remove duplicated all and clean
target"), the "all" target was removed from individual Makefiles and
added to lib.mk.

However the "all" target was added to lib.mk *after* the existing
"runtests" target. This means "runtests" becomes the first (default)
target for most of our Makefiles.

This has the effect of causing a plain "make" to build *and run* the
tests. Which is at best rude, but depending on which tests are run could
oops someone's build machine.

  $ make -C tools/testing/selftests/
  ...
  make[1]: Entering directory 'tools/testing/selftests/bpf'
  gcc -Wall -O2 -I../../../../usr/include   test_verifier.c -o tools/testing/selftests/bpf/test_verifier
  gcc -Wall -O2 -I../../../../usr/include   test_maps.c -o tools/testing/selftests/bpf/test_maps
  gcc -Wall -O2 -I../../../../usr/include   test_lru_map.c -o tools/testing/selftests/bpf/test_lru_map
  #0 add+sub+mul FAIL
  Failed to load prog 'Function not implemented'!
  #1 unreachable FAIL
  Unexpected error message!
  #2 unreachable2 FAIL
  ...

Fix it by moving the "all" target to the start of lib.mk, making it the
default target.
