[Why] We can hang in place trying to send commands when the DMCUB isn't powered on. [How] For functions that execute within a DC context or DC lock we can wrap the direct calls to dm_execute_dmub_cmd/list with code that exits idle power optimizations and reallows once we're done with the command submission on success. For DM direct submissions the DM will need to manage the enter/exit sequencing manually. We cannot invoke a DMCUB command directly within the DM execution helper or we can deadlock. Reviewed-by:

This reverts commit b8c415e3 ("drm/amdgpu: take runtime pm reference when we attach a buffer") and commit 425285d3 ("drm/amdgpu: add amdgpu runpm usage trace for separate funcs"). Taking a runtime pm reference for DMA-buf is actually completely unnecessary and even dangerous. The problem is that calling pm_runtime_get_sync() from the DMA-buf callbacks is illegal because we have the reservation locked here which is also taken during resume. So this would deadlock. When the buffer is in GTT it is still accessible even when the GPU is powered down and when it is in VRAM the buffer gets migrated to GTT before powering down. The only use case which would make it mandatory to keep the runtime pm reference would be if we pin the buffer into VRAM, and that's not something we currently do. v2: improve the commit message Signed-off-by:

We need to take the reset domain lock before talking to MES. While in this case we can take the lock inside the mes helper. We can't do so for most other mes helpers since they are used during reset. So for consistency sake we add the lock here. Signed-off-by:

Currently, amdgpu will always set up the brightness at 100% when it loads. However this is jarring when the BIOS has it previously programmed to a much lower value. The ACPI ATIF method includes two members for "ac_level" and "dc_level". These represent the default values that should be used if the system is brought up in AC and DC respectively. Use these values to set up the default brightness when the backlight device is registered. v2: squash in ACPI fix Reviewed-by:

Which method is used to flush tlb does not depend on whether a reset is in progress or not. We should skip flush altogether if the GPU will get reset. So put both path under reset_domain read lock. Signed-off-by:

is_hws_hang and is_resetting serves pretty much the same purpose and they all duplicates the work of the reset_domain lock, just check that directly instead. This also eliminate a few bugs listed below and get rid of dqm->ops.pre_reset. kfd_hws_hang did not need to avoid scheduling another reset. If the on-going reset decided to skip GPU reset we have a bad time, otherwise the extra reset will get cancelled anyway. remove_queue_mes forgot to check is_resetting flag compared to the pre-MES path unmap_queue_cpsch, so it did not block hw access during reset correctly.

We send back the ready to reset message before we stop anything. This is wrong. Move it to when we are actually ready for the FLR to happen. In the current state since we take tens of seconds to stop everything, it is very likely that host would give up waiting and reset the GPU before we send ready, so it would be the same as before. But this gets rid of the hack with reset_domain locking and also let us tell how slow ready to reset actually is from the host. The ready to reset speed can be improved later. Signed-off-by:
