drm/amdkfd: Add 64-bit doorbell and wptr support to kernel queue

drm/amdkfd: Fix kernel queue rollback_packet

2018-04-10T21:33:12+00:00

kq->queue->properties.write_ptr is a GPU address which can'd be derefenced in the kernel. Use kq->wptr_kernel instead, which is the kernel CPU address of the same buffer. Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Fix goto usage

2018-04-10T21:33:11+00:00

Missed a spot in previous cleanup commit: Remove gotos that do not feature any common cleanup, and use gotos instead of repeating cleanup commands. According to kernel.org: "The goto statement comes in handy when a function exits from multiple locations and some common work such as cleanup has to be done. If there is no cleanup needed then just return directly." Signed-off-by: Kent Russell Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Hardware DWORD size is 4 bytes

2017-11-06T19:52:27+00:00

Don't use sizeof(uint32_t) or similar types for hardware or firmware DWORD size. The hardware and firmware don't care about Linux types. Signed-off-by: Felix Kuehling Reviewed-by: Alex Deucher Signed-off-by: Oded Gabbay

drm/amdkfd: Reuse CHIP_* from amdgpu v2

2017-09-20T22:10:19+00:00

There are already CHIP_* definitions under amd_shared.h file on amdgpu side, so KFD should reuse them rather than defining new ones. Using enum for asic type requires default cases on switch statements to prevent compiler warnings. WARN on unsupported ASICs. It should never get there because KFD should not be initialized on unsupported devices. v2: Replace BUG() with WARN and error return Signed-off-by: Yong Zhao Signed-off-by: Felix Kuehling Signed-off-by: Oded Gabbay

drm/amdkfd: Adjust dequeue latencies and timeouts

2017-09-20T22:10:16+00:00

Adjust latencies and timeouts for dequeueing with HWS and consolidate them in one place. Make them longer to allow long running waves to complete without causing a timeout. The timeout is twice as long as the latency plus some buffer to make sure we don't detect a timeout prematurely. Change timeouts for dequeueing HQDs without HWS. KFD_UNMAP_LATENCY is more consistent with what the HWS does for user queues. Signed-off-by: Yong Zhao Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Fix kernel-queue wrapping bugs

2017-09-20T22:10:21+00:00

Avoid intermediate negative numbers when doing calculations with a mix of signed and unsigned variables where implicit conversions can lead to unexpected results. When kernel queue buffer wraps around to 0, we need to check that rptr won't be overwritten by the new packet. Signed-off-by: Yong Zhao Signed-off-by: Felix Kuehling Signed-off-by: Oded Gabbay

drm/amdkfd: pass queue's mqd when destroying mqd

2017-09-02T12:00:25+00:00

In VI, the destroy mqd function needs to inquire fields present in the mqd structure. That's why we need to pass it to that function instead of NULL. Signed-off-by: Oded Gabbay
