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.

2022-10-24drm/amd/display: Remove FPU guards from the DML folderRodrigo Siqueira2-18/+1
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.

2022-10-24drm/amd/display: Remove wrong pipe control lockRodrigo Siqueira1-11/+1
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.

2022-10-24drm/amd/display: Use update plane and stream routine for DCN32xRodrigo Siqueira1-0/+12
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.

2022-10-24drm/amd/display: Add function for validate and update new streamRodrigo Siqueira3-14/+227
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.

Currently, if we encounter unimplemented functions, it is difficult to tell what caused them just by looking at dmesg and that is compounded by the fact that it is often hard to reproduce said issues, for instance we have had reports of this condition being triggered when removing a secondary display that is setup in mirror mode and is connected using usb-c.

2022-10-10drm/amd/display: fix array-bounds error in dc_stream_remove_writeback() [take 2]Guenter Roeck1-2/+2
Commit 5d8c3e836fc2 ("drm/amd/display: fix array-bounds error in dc_stream_remove_writeback()") tried to fix an array bounds error seen with gcc 12.0. Unfortunately, that results in another array bounds error, seen with older versions of gcc. Building csky:allmodconfig ... failed -------------- Error log: drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_stream.c: In function 'dc_stream_remove_writeback': drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_stream.c:527:83: error: array subscript 1 is above array bounds of 'struct dc_writeback_info[1]' [-Werror=array-bounds] 527 | stream->writeback_info[j] = stream->writeback_info[i]; | ~~~~~~~~~~~~~~~~~~~~~~^~~ In file included from drivers/gpu/drm/amd/amdgpu/../display/dc/dc.h:1269, from drivers/gpu/drm/amd/amdgpu/../display/dc/inc/core_types.h:29, from drivers/gpu/drm/amd/amdgpu/../display/dc/basics/dc_common.h:29, from drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_stream.c:27: drivers/gpu/drm/amd/amdgpu/../display/dc/dc_stream.h:241:34: note: while referencing 'writeback_info' 241 | struct dc_writeback_info writeback_info[MAX_DWB_PIPES]; We could check both i and j for overflow to fix the problem. That would, however, be not make much sense since it is known and provable that j <= i. Also, the check introduced with commit 5d8c3e836fc2 does not really add value since it checks if j < MAX_DWB_PIPES. Since it is known that j <= i, it would make more sense to check if i < MAX_DWB_PIPES. Unfortunately, that does not help to solve the problem observed here: gcc still complains. To solve the problem, replace the subsequent check for 'i != j' with 'j < i'. This is identical to the original check since we know that j <= i, and it makes all versions of gcc happy. Drop the check introduced with commit 5d8c3e836fc2 since it is not really useful and does not solve the problem.

The struct timing_generator_funcs provides a hook for setting up the maximum possible vertical dimension of display for OTG, as the panel supports. DCN10 has a standard function named optc1_set_vtotal_min_max which all ASICs can use to set the aforementioned hook. Since we did not set it for DCN20, this commit initializes the set_vtotal_min_max with the DCN10 function.

2022-10-10drm/amd/display: Display does not light up after S4 resumeMeenakshikumar Somasundaram2-0/+34
[Why] Dpia hpd interrupt processing is disabled when entering S4/S0i3 and would be reenabled after detection completes during resuming. Because, keeping hpd interrupts enabled during detection leads to multiple detections for the same hpd transition. There is a S4 case where dpia hpd interrupt is missed when driver is in transitioning from hpd interrupt processing disable to enable and the display does not light up. [How] - Added dmub inbox command DMUB_CMD__DPIA_HPD_INT_ENABLE to explicitly control dmub to issue dpia hpd interrupt or not. If dpia hpd interrupt is disabled, dmub will keep the hpd pending and post it once driver reenables dpia hpd interrupt or when querying with DMUB_CMD__QUERY_HPD_STATE. - Added dmub boot option dpia_hpd_int_enable_supported to notify dmub about whether DMUB_CMD__DPIA_HPD_INT_ENABLE command would be used.
