To prevent warnings like this from happening in the future, make the SOC15_WAIT_ON_RREG macro initialize its ret variable before the while loop that can time out. This macro's return value is always checked so it should set ret in both the success and fail path. Link: https://github.com/ClangBuiltLinux/linux/issues/776 Signed-off-by:

It may lose gpuvm invalidate acknowldege state across power-gating off cycle. To avoid this issue in gmc9/gmc10 invalidation, add semaphore acquire before invalidation and semaphore release after invalidation. After adding semaphore acquire before invalidation, the semaphore register become read-only if another process try to acquire semaphore. Then it will not be able to release this semaphore. Then it may cause deadlock problem. If this deadlock problem happens, it needs a semaphore firmware fix. Signed-off-by:

Only for the debugger use case. [why] Avoid endless translation retries, after an invalid address access has been issued to the GPU. Instead, the trap handler is forced to enter by generating a no-retry-fault. A s_trap instruction is inserted in the debugger case to let the wave to enter trap handler to save context. [how] Intentionally using an invalid flag combination (F and P set at the same time) to trigger a no-retry-fault, after a retry-fault happens. This is only valid under compute context. Signed-off-by:
