2018-07-11 | drm/amdkfd: Fix race between scheduler and context restore | 1 | -225/+233 | ||
The scheduler may raise SQ_WAVE_STATUS.SPI_PRIO via SQ_CMD before context restore has completed. Restoring SPI_PRIO=0 after this point may cause context save to fail as the lower priority wavefronts are not selected for execution among spin-waiting wavefronts. Leave SPI_PRIO at its SPI-initialized or scheduler-raised value. v2: Also fix race with exception handler Signed-off-by: Jay Cornwall <Jay.Cornwall@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Felix Kuehling <Felix.Kuehling@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> | |||||
2018-05-01 | drm/amdkfd: Fix CP soft hang on APUs | 1 | -2/+2 | ||
The problem happens on Raven and Carrizo. The context save handler should not clear the high bits of PC_HI before extracting the bits of IB_STS. The bug is not relevant to VEGA10 until we enable demand paging.

2018-05-01 | drm/amdkfd: Separate trap handler assembly code and its hex values | 1 | -0/+560 | ||
Since the assembly code is inside "#if 0", it is ineffective. Despite that, during debugging, we need to change the assembly code, extract it into a separate file and compile the new file into hex values using sp3. That process also requires us to remove "#if 0" and modify lines starting with "#", so that sp3 can successfully compile the new file. With this change, all the above chore is no longer needed, and cwsr_trap_handler_gfx*.asm can be directly used by sp3 to generate its hex values.
