start_cpsch and stop_cpsch can be called during kfd device initialization or during gpu reset/recovery. So they can run concurrently. Currently in start_cpsch and stop_cpsch, pm_init and pm_uninit is not protected by the dpm lock. Imagine such a case that user use packet manager's function to submit a pm4 packet to hang hws (ie through command cat /sys/class/kfd/kfd/topology/nodes/1/gpu_id | sudo tee /sys/kernel/debug/kfd/hang_hws), while kfd device is under device reset/recovery so packet manager can be not initialized. There will be unpredictable protection fault in such case. This patch moves pm_init/uninit inside the dpm lock and check packet manager is initialized before using packet manager function.

Function name "psp_np_fw_load" is not proper as people don't know _np_fw_ means "non psp firmware". Change the function name to psp_load_non_psp_fw for better understanding. Same thing for function psp_execute_np_fw_load. Signed-off-by:

The printing message "PSP loading VCN firmware" is mis-leading because people might think driver is loading VCN firmware. Actually when this message is printed, driver is just preparing some VCN ucode, not loading VCN firmware yet. The actual VCN firmware loading will be in the PSP block hw_init. Fix the printing message Signed-off-by:

[why] There's a special case where upper plane is not the main plane. If it owns the cursor, it will be invisible in the majority of the screen. [How] The condition for disabling cursor is changed: - check if upper viewport completely covers current. This was the previous change that doesn't handle all scenarios with pipe splitting. - if not, show the cursor only if it's not scaled or no upper pipe. Reviewed-by:

DCN 3x increased Line buffer size for DCHUB latency hiding, from 4 lines of 4K resolution lines to 5 lines of 4K resolution lines. All Line Buffer can be used as extended memory for P State change latency hiding. The maximum number of lines is increased to 32 lines. Finally, LB_MEMORY_CONFIG_1 (LB memory piece 1) and LB_MEMORY _CONFIG_2 (LB memory piece 2) are not affected, no change in size, only 3 pieces is affected, i.e., when all 3 pieces are used in both LB_MEMORY_CONFIG_0 and LB_MEMORY_CONFIG_3 (for 4:2:0) modes.

[Why] Vertical and horizontal borders in timings are treated as increasing the active area - vblank and hblank actually shrink. Our input into DML does not include these borders so it incorrectly assumes it has more time than available for vstartup and tmdl calculations for some modes with borders. An example of such a timing would be 640x480@72Hz: h_total: 832 h_border_left: 8 h_addressable: 640 h_border_right: 8 h_front_porch: 16 h_sync_width: 40 v_total: 520 v_border_top: 8 v_addressable: 480 v_border_bottom: 8 v_front_porch: 1 v_sync_width: 3 pix_clk_100hz: 315000 [How] Include borders as part of destination vactive/hactive. This change DCN20+ so it has wide impact, but the destination vactive and hactive are only really used for vstartup calculation anyway. Most modes do not have vertical or horizontal borders.

[Why] Theoretically, per DP 1.4a spec, sink device needs to AUX_ACK 00340h write. However, due to hardware limitation, some sink devices have no 00340h dpcd address at all. This results in sink side fails to reply ACK, and consequently cause source side keep retrying DPCD write on DPCD 00340h. This results in significant delay when DPCD 00340h write is triggered (e.g. at S3 resume). [How] Check whether sink device could ACK on DPCD 00340h write on boot. If sink device fails to ACK, then remember that, so we won't write to DPCD 00340h later on. There will be a drm.debug KMS level message to inform user once a 00340h DPCD write is skipped on purpose.

This tends to take miliseconds in certain scenarios and we'd rather not wait that long. Due to how this interacts with det size update and locking waiting should not be necessary as compbuf updates before unlock.
