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

selftests/powerpc: Add TM test to check if TAR is corrupted

2016-05-11T11:54:13+00:00

If the transaction is aborted, the TAR should be rolled back to the checkpointed value before the transaction began. The value written to the TAR when the transaction is suspended should only remain there if the transaction completes successfully. Signed-off-by: Rashmica Gupta Signed-off-by: Michael Ellerman

selftests/powerpc: Add test for forking inside transaction

2016-05-11T11:54:13+00:00

This test does a fork syscall inside a transaction. Basic sniff test to see if we can enter the kernel during a transaction. Signed-off-by: Rashmica Gupta Signed-off-by: Michael Ellerman

selftests/powerpc: Add test to check if VSRs are corrupted

2015-12-14T09:41:50+00:00

When a transaction is aborted, VSR values should rollback to the checkpointed values before the transaction began. VSRs used elsewhere in the kernel during a transaction, or while the transaction is suspended should not affect the checkpointed values. Prior to the bug fix in commit d31626f70b61 ("powerpc: Don't corrupt transactional state when using FP/VMX in kernel") when VMX was requested by the kernel the .vr_state (which held the checkpointed state of VSRs before the transaction) was overwritten with the current state from outside the transation. Thus if the transaction did not complete, the VSR values would be "rolled back" to potentially incorrect values. Signed-off-by: Rashmica Gupta Signed-off-by: Michael Ellerman

selftests/powerpc: Add TM signal with invalid stack test

2015-12-14T09:41:49+00:00

Test the kernels signal generation code to ensure it can handle an invalid stack pointer when transactional. Signed-off-by: Michael Neuling Tested-by: Anshuman Khandual [mpe: Skip if we don't have TM] Signed-off-by: Michael Ellerman
