this set adds support for removal of gpu drm dead code. patch3 is similar with patch 1: `num` is a data of u8 type and ATOM_MAX_HW_I2C_READ == 255, so there is a impossible condition '(num > 255) => (0-255 > 255)'. Signed-off-by:

Add a safety check to runtime suspend to make sure all outstanding fences have signaled before we suspend. Doesn't fix any known issue. We already do this via the fence driver suspend function, but we just force completion rather than bailing. This bails on runtime suspend so we can try again later once the fences are signaled to avoid missing any outstanding work. Reviewed-by:

issues: MEC is ruined by the amdkfd_pre_reset after VF FLR done fix: amdkfd_pre_reset() would ruin MEC after hypervisor finished the VF FLR, the correct sequence is do amdkfd_pre_reset before VF FLR but there is a limitation to block this sequence: if we do pre_reset() before VF FLR, it would go KIQ way to do register access and stuck there, because KIQ probably won't work by that time (e.g. you already made GFX hang) so the best way right now is to simply remove it.

issues: gpu_recover() is re-entered by the mailbox interrupt handler mxgpu_nv.c fix: we need to bypass the gpu_recover() invoke in mailbox interrupt as long as the timeout is not infinite (thus the TDR will be triggered automatically after time out, no need to invoke gpu_recover() through mailbox interrupt.

Entity currently keeps a copy of run_queue list and modify it in drm_sched_entity_set_priority(). Entities shouldn't modify run_queue list. Use drm_gpu_scheduler list instead of drm_sched_rq list in drm_sched_entity struct. In this way we can select a runqueue based on entity/ctx's priority for a drm scheduler. Signed-off-by:

Increment the usage count in emit fence, and decrement in process fence to make sure the GPU is always considered in use while there are fences outstanding. We always wait for the engines to drain in runtime suspend, but in practice that only covers short lived jobs for gfx. This should cover us for longer lived fences. Reviewed-by:

[Why] Cursor disappears for some SLS displays that are rotated 180 and 270 degrees. This occurs when there is no pipe split being done ( ex. 3 or more displays ). The cursor calculations assume pipe splitting is done so when it calculates the new cursor position in hwss.set_cursor_position(), it is out-of-bounds so it disables the cursor in hubp.set_cursor_position(). [How] In non pipe split cases, calculate cursor using viewport size ( width or height ) instead of viewport size * 2 ( the two because pipe splitting divides the rectangle into two ). Signed-off-by:
