selftests/powerpc: Specify we expect to build with std=gnu99

2016-08-10T13:21:37+00:00

We have some tests that assume we're using std=gnu99, which is fine on most compilers, but some old compilers use a different default. So make it explicit that we want to use std=gnu99. Signed-off-by: Michael Ellerman

selftests/powerpc: Test unaligned copy and paste

2016-07-05T13:49:51+00:00

Test that an ISA 3.0 compliant machine performing an unaligned copy, copy_first, paste or paste_last is sent a SIGBUS. Signed-off-by: Chris Smart Signed-off-by: Michael Ellerman

selftests/powerpc: Test cp_abort during context switch

2016-05-11T11:54:01+00:00

Test that performing a copy paste sequence in userspace on P9 does not result in a leak of the copy into the paste of another process. This is based on Anton Blanchard's context_switch benchmarking code. It sets up two processes tied to the same CPU, one which copies and one which pastes. The paste should never succeed and the test fails if it does. This is a test for commit, "8a64904 powerpc: Add support for userspace P9 copy paste."

selftests/powerpc: Test the preservation of FPU and VMX regs across syscall

2016-03-02T12:34:46+00:00

Test that the non volatile floating point and Altivec registers get correctly preserved across the fork() syscall. fork() works nicely for this purpose, the registers should be the same for both parent and child Signed-off-by: Cyril Bur [mpe: Add include guards to basic_asm.h, minor formatting] Signed-off-by: Michael Ellerman

selftests/powerpc: Remove -flto from common CFLAGS

2016-03-02T12:34:46+00:00

LTO can cause GCC to inline some functions which have attributes set. The act of inlining the functions can lead to GCC forgetting about the attributes which leads to incorrect tests. Notable example being: __attribute__((__target__("no-vsx"))) LTO can also interact strangely with custom assembly functions and cause tests to intermittently fail. Both these cases are hard to detect and require manual inspection of binaries which is unlikely to happen for all tests. Furthermore, LTO optimisations are not necessary for selftests and correctness is paramount and as such it is best to disable LTO. LTO can be enabled on a per test basis. A pseries_le_defconfig kernel on a POWER8 was used to determine that the same subset of selftests pass and fail with and without -flto in the common Makefile.

selftests/powerpc: Sort the list of SUB_DIRS to build

2015-10-15T09:32:03+00:00

This list has gotten too long. Split it into individual lines and sort them, so in future we can add new entries more cleanly. Signed-off-by: Michael Ellerman

selftests/powerpc: Add tests of unmuxed IPC calls

2015-10-15T09:32:03+00:00

This is just a simple test which confirms that the individual IPC syscalls are all available. Signed-off-by: Michael Ellerman

powerpc/selftest: Add gettimeofday() benchmark

2015-10-01T06:52:02+00:00

This adds a benchmark directory to the powerpc selftests and adds a gettimeofday() benchmark to it. Suggested-by: Michael Ellerman Signed-off-by: Michael Neuling Signed-off-by: Michael Ellerman

selftests/powerpc: Add test for system wide DSCR default

2015-06-07T09:35:38+00:00

This patch adds a test case for the system wide DSCR default value, which when changed through it's sysfs interface must be visible to all threads reading DSCR either through the privilege state SPR or the problem state SPR. The DSCR value change should be immediate as well. Acked-by: Shuah Khan Signed-off-by: Anshuman Khandual Signed-off-by: Anton Blanchard Signed-off-by: Michael Ellerman
