powerpc/selftests: Wait all threads to join

2018-11-21T08:25:57+00:00

[ Upstream commit 693b31b2fc1636f0aa7af53136d3b49f6ad9ff39 ] Test tm-tmspr might exit before all threads stop executing, because it just waits for the very last thread to join before proceeding/exiting. This patch makes sure that all threads that were created will join before proceeding/exiting. This patch also guarantees that the amount of threads being created is equal to thread_num.

selftests/powerpc: Fix TM resched DSCR test with some compilers

2018-04-13T17:48:02+00:00

[ Upstream commit fe06fe860250a4f01d0eaf70a2563b1997174a74 ] The tm-resched-dscr test has started failing sometimes, depending on what compiler it's built with, eg: test: tm_resched_dscr Check DSCR TM context switch: tm-resched-dscr: tm-resched-dscr.c:76: test_body: Assertion `rv' failed. !! child died by signal 6 When it fails we see that the compiler doesn't initialise rv to 1 before entering the inline asm block. Although that's counter intuitive, it is allowed because we tell the compiler that the inline asm will write to rv (using "=r"), meaning the original value is irrelevant. Marking it as a read/write parameter would presumably work, but it seems simpler to fix it by setting the initial value of rv in the inline asm.

Some of the recent new selftests were missing additions to .gitignore, add them now. Signed-off-by: Michael Ellerman

selftests/powerpc: Add checks for transactional VSXs in signal contexts

2016-10-04T09:33:15+00:00

If a thread receives a signal while transactional the kernel creates a second context to show the transactional state of the process. This test loads some known values and waits for a signal and confirms that the expected values are in the signal context. Signed-off-by: Cyril Bur Signed-off-by: Michael Ellerman

selftests/powerpc: exec() with suspended transaction

2016-07-26T04:28:22+00:00

Perform an exec() class syscall with a suspended transaction. This is a test for the bug we fixed in 8e96a87c5431 ("powerpc/tm: Always reclaim in start_thread() for exec() class syscalls").

selftests/powerpc: Add test to check if TM SPRs are corrupted

2016-05-11T11:54:14+00:00

Testing that the TM SPRs are behaving the way they should. Uses more threads than cpus to see if the following register values persist with context switching: - the FS (failure summary) flag in TEXASR - TFIAR and TFHAR Signed-off-by: Rashmica Gupta Signed-off-by: Michael Ellerman
