2022-10-24drm/amd/display: Remove FPU guards from the DML folderRodrigo Siqueira
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/amdgpu: fix sdma doorbell init ordering on APUsAlex Deucher
Commit 8795e182b02d ("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.

2022-10-24drm/amd/display: Remove wrong pipe control lockRodrigo Siqueira
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 Siqueira
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 Siqueira
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.

2022-10-24drm/i915/dgfx: Keep PCI autosuspend control 'on' by default on all dGPUAnshuman Gupta
DGFX platforms has lmem and cpu can access the lmem objects via mmap and i915 internal i915_gem_object_pin_map() for i915 own usages. Both of these methods has pre-requisite requirement to keep GFX PCI endpoint in D0 for a supported iomem transaction over PCI link. (Refer PCIe specs 5.3.1.4.1) Both DG1/DG2 have a known hardware bug that violates the PCIe specs and support the iomem read write transaction over PCIe bus despite endpoint is D3 state. Due to above H/W bug, we had never observed any issue with i915 runtime PM versus lmem access. But this issue becomes visible when PCIe gfx endpoint's upstream bridge enters to D3, at this point any lmem read/write access will be returned as unsupported request. But again this issue is not observed on every platform because it has been observed on few host machines DG1/DG2 endpoint's upstream bridge does not bind with pcieport driver. which really disables the PCIe power savings and leaves the bridge at D0 state. We need a unique interface to read/write from lmem with runtime PM wakeref protection something similar to intel_uncore_{read, write}, keep autosuspend control to 'on' on all discrete platforms, until we have a unique interface to read/write from lmem. This just change the default autosuspend setting of i915 on dGPU, user can still change it to 'auto'. v2: - Modified the commit message and subject with more information. - Changed the Fixes tag to LMEM support commit.

2022-10-24drm/bridge: it6505: Improve synchronization between extcon subsystemPin-yen Lin
Originally, the it6505 relies on a short sleep in the IRQ handler and a long sleep to make sure it6505->lane_swap and it6505->lane_count is configured in it6505_extcon_work and it6505_detect, respectively. Use completion and additional DPCD read to remove the unnecessary waits, and use a different lock for it6505_extcon_work and the threaded IRQ handler because they no longer need to run exclusively. The wait time of the completion is usually less than 10ms in local experiments, but leave it larger here just in case.

Move the DPCD read and link setup steps to HPD IRQ handler to remove an unnecessary dependency between .detect callback and the HPD IRQ handler before registering it6505 as a DRM bridge.

2022-10-22drm/i915: Don't flag both full modeset and fastset at the same timeVille Syrjälä
Be consistent in whether we flag a full modeset or a fastset for the pipe. intel_modeset_all_pipes() would seem to be the only codepath not getting this right. The other case is when we flag the fastset initially, currently we just clear the mode_changed flag and set the update_pipe flag. But we could still have connectors_changed==true or active_changed==true forcing a full modeset anyway. So check for that after clearing the mode_changed flag. And let's add a WARN to make sure we did get it right. v2: Deal with {connectors,active}_changed Reviewed-by: Jani Nikula <jani.nikula@intel.com> #v1 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221021162442.27283-4-ville.syrjala@linux.intel.com

2022-10-22drm/i915: Activate DRRS after state readoutVille Syrjälä
On BDW+ we have just the one set of DP M/N registers. The values we write into said registers depends on whether we want DRRS to be in high or low gear. This causes issues for the state checker which currently has to assume either set of M/N (high or low refresh rate) values may appear there. That sort of works for M/N itself, but all other values derived from the M/N (dotclock, pixel rate) are not handled correctly, leading to potential for state checker mismatches. Let's avoid all those problems by simply keeping DRRS in high gear until the state checker has done its hardware state readout. Note that hitting this issue presumable became very hard after commit 1b333c679a0f ("drm/i915: Do DRRS disable/enable during pre/post_plane_update()") since the state check would have to laze about for one full second (delay used by intel_drrs_schedule_work()) to see the low refresh rate. But it is still theoretically possible.
