VPG doesn't have the ability to mute audio output by sending all 0s in audio SDP. The existing implemention is disabling audio SDP instead. This is same as what dp_audio_enable does. Since it is no longer referenced by any callers, we decided to remove this interface for simplicity. Tested-by:

As part of the programming expectation for using DML functions, DC requires that any DML function invoked outside DML uses: DC_FP_START(); ... dml function ... DC_FP_END(); Additionally, all the DML functions that can be invoked outside the DML folder call the function dc_assert_fp_enabled(), which is responsible for triggering a warning in the case that the DML function was not guarded by the DC_FP_START/END. For this reason, call DC_FP_START/END inside DML is wrong, and this commit removes all of those references. Tested-by:

Commit 8795e182 ("PCI/portdrv: Don't disable AER reporting in get_port_device_capability()") uncovered a bug in amdgpu that required a reordering of the driver init sequence to avoid accessing a special register on the GPU before it was properly set up leading to an PCI AER error. This reordering uncovered a different hw programming ordering dependency in some APUs where the SDMA doorbells need to be programmed before the GFX doorbells. To fix this, move the SDMA doorbell programming back into the soc15 common code, but use the actual doorbell range values directly rather than the values stored in the ring structure since those will not be initialized at this point. This is a partial revert, but with the doorbell assignment fixed so the proper doorbell index is set before it's used.

When using a device based on DCN32/321, we have an issue where a second 4k@60Hz display does not light up, and the system becomes unresponsive for a few minutes. In the debug process, it was possible to see a hang in the function dcn20_post_unlock_program_front_end in this part: for (j = 0; j < TIMEOUT_FOR_PIPE_ENABLE_MS*1000 && hubp->funcs->hubp_is_flip_pending(hubp); j++) mdelay(1); } The hubp_is_flip_pending always returns positive for waiting pending flips which is a symptom of pipe hang. Additionally, the dmesg log shows this message after a few minutes: BUG: soft lockup - CPU#4 stuck for 26s! ... [ +0.000003] dcn20_post_unlock_program_front_end+0x112/0x340 [amdgpu] [ +0.000171] dc_commit_state_no_check+0x63d/0xbf0 [amdgpu] [ +0.000155] ? dc_validate_global_state+0x358/0x3d0 [amdgpu] [ +0.000154] dc_commit_state+0xe2/0xf0 [amdgpu] This confirmed the hypothesis that we had a pipe hanging somewhere. Next, after checking the ftrace entries, we have the below weird sequence: [..] 2) | dcn10_lock_all_pipes [amdgpu]() { 2) 0.120 us | optc1_is_tg_enabled [amdgpu](); 2) | dcn20_pipe_control_lock [amdgpu]() { 2) | dc_dmub_srv_clear_inbox0_ack [amdgpu]() { 2) 0.121 us | amdgpu_dm_dmub_reg_write [amdgpu](); 2) 0.551 us | } 2) | dc_dmub_srv_send_inbox0_cmd [amdgpu]() { 2) 0.110 us | amdgpu_dm_dmub_reg_write [amdgpu](); 2) 0.511 us | } 2) | dc_dmub_srv_wait_for_inbox0_ack [amdgpu]() { 2) 0.110 us | amdgpu_dm_dmub_reg_read [amdgpu](); 2) 0.110 us | amdgpu_dm_dmub_reg_read [amdgpu](); 2) 0.110 us | amdgpu_dm_dmub_reg_read [amdgpu](); 2) 0.110 us | amdgpu_dm_dmub_reg_read [amdgpu](); 2) 0.110 us | amdgpu_dm_dmub_reg_read [amdgpu](); 2) 0.110 us | amdgpu_dm_dmub_reg_read [amdgpu](); 2) 0.110 us | amdgpu_dm_dmub_reg_read [amdgpu](); [..] We are not expected to read from dmub register so many times and for so long. From the trace log, it was possible to identify that the function dcn20_pipe_control_lock was triggering the dmub operation when it was unnecessary and causing the hang issue. This commit drops the unnecessary dmub code and, consequently, fixes the second display not lighting up the issue. Tested-by: -

Sub-viewport (Subvp) feature is used for changing MCLK without causing any display artifact, requiring special treatment from the plane and stream perspective since DC needs to read data from the cache when using subvp. However, the function dc_commit_updates_for_stream does not provide all the support needed by this feature which will make this function legacy at some point. For this reason, this commit enables dc_update_planes_and_stream for ASICs that support this feature but preserves the old behavior for other ASICs. However, dc_update_planes_and_stream should replace dc_commit_updates_for_stream for all ASICs since it does most of the tasks executed by dc_commit_updates_for_stream with other extra operations, but we need to run tests before making this change.

A seamless boot stream has hardware resources assigned to it, and adding a new stream means rebuilding the current assignment. It is desirable to avoid this situation since it may cause light-up issues on the VGA monitor on USB-C. This commit swaps the seamless boot stream to pipe 0 (if necessary) to ensure that the pipe context matches. Reviewed-by:

DC stream can be seen as a representation of the DCN backend or the data struct that represents the center of the display pipeline. The front end (i.e., planes) is connected to the DC stream, and in its turn, streams are connected to the DC link. Due to this dynamic, DC must handle the following scenarios: 1. A stream is removed; 2. A new stream is created; 3. An unchanged stream had some updates on its planes. These combinations require that the new stream data struct become updated and has a valid global state. For handling multiple corner cases associated with stream operations, this commit introduces a function dedicated to manipulating stream changes and invokes the state validation function after that.

DC adds an instance of DML (which contains VBA) to each context, and multiple threads might write back to the global VBA resulting in data overwriting. To keep the consistency with other parts of the DC code, this commit changes dc_commit_streams to copy the current DC state, and as a result, it also changes the function signature to expect streams instead of a context.

Change commit sequence will impact all ASICs. It is prudent to run this update in small steps to keep issues under control and avoid any potential regression. With this idea in mind, this commit is preparation work for the complete transition to the new commit sequence. To maintain this change manageable across multiple ASICs, this commit adds a new function named dc_commit_streams which is a copy of the dc_commit_state with some minor changes. Finally, inside the dc_commit_state, we check if we are using DCN32x or above and enable the new sequence only for those devices. Reviewed-by:
