2024-10-14drm/i915/dp_mst: Handle error during DSC BW overhead/slice calculationImre Deak
The MST branch device may not support the number of DSC slices a mode requires, handle the error in this case.

2024-10-11drm/i915/xe3lpd: Add new display power wellsMatt Roper
Xe3's power well handling is similar to previous platforms, but there are a few changes that need to be handled to ensure optimal power management: - PGB now only depends on PG1, not PG2 - Transcoder B is now in PG1 (was previously in PGB) - Transcoders C & D are now in PG2 (were previously in PGC/PGD) - DC states now require PG2 to be off (whereas on Xe2 it could remain on as a dependency of PGB, although the features inside of it could not be used).

2024-10-11drm/i915/dp: Disable unnecessary HPD polling for eDPImre Deak
A registered eDP connector is considered to be always connected, so it's unnecessary to poll it for a connect/disconnect event. Polling it involves AUX accesses toggling the panel power, which in turn can generate a spurious short HPD pulse and possibly a new poll cycle via the short HPD handler runtime resuming the device. Avoid this by disabling the polling for eDP connectors. This avoids IGT tests timing out while waiting for the device to runtime suspend, the timeout caused by the above runtime resume->poll->suspend-> resume cycle keeping the device in the resumed state.

2024-10-11drm/i915/dp: Assume panel power is off if runtime suspendedImre Deak
If the device is runtime suspended the eDP panel power is also off. Ignore a short HPD on eDP if the device is suspended accordingly, instead of checking the panel power state via the PPS registers for the same purpose. The latter involves runtime resuming the device unnecessarily, in a frequent scenario where the panel generates a spurious short HPD after disabling the panel power and the device is runtime suspended.

2024-10-10drm/xe: fix unbalanced rpm put() with fence_fini()Matthew Auld
Currently we can call fence_fini() twice if something goes wrong when sending the GuC CT for the tlb request, since we signal the fence and return an error, leading to the caller also calling fini() on the error path in the case of stack version of the flow, which leads to an extra rpm put() which might later cause device to enter suspend when it shouldn't. It looks like we can just drop the fini() call since the fence signaller side will already call this for us. There are known mysterious splats with device going to sleep even with an rpm ref, and this could be one candidate. v2 (Matt B): - Prefer warning if we detect double fini() Fixes: 0a382f9bc5dc ("drm/xe: Hold a PM ref when GT TLB invalidations are inflight") Signed-off-by: Matthew Auld <matthew.auld@intel.com> Cc: Matthew Brost <matthew.brost@intel.com> Cc: Nirmoy Das <nirmoy.das@intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Nirmoy Das <nirmoy.das@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241009084808.204432-3-matthew.auld@intel.com

2024-10-09drm/vc4: Run default client setup for all variants.Dave Stevenson
Commit 45903624e9fc ("drm/vc4: Run DRM default client setup") only added DRM_FBDEV_DMA_DRIVER_OPS for the vc4 (Pi0-3) driver definition, which caused an issue on vc5 (Pi4) as there was no fbdev_probe function defined.

2024-10-09drm/xe/bmg: improve cache flushing behaviourMatthew Auld
The BSpec says that EN_L3_RW_CCS_CACHE_FLUSH must be toggled on for manual global invalidation to take effect and actually flush device cache, however this also turns on flushing for things like pipecontrol, which occurs between submissions for compute/render. This sounds like massive overkill for our needs, where we already have the manual flushing on the display side with the global invalidation. Some observations on BMG: 1. Disabling l2 caching for host writes and stubbing out the driver global invalidation but keeping EN_L3_RW_CCS_CACHE_FLUSH enabled, has no impact on wb-transient-vs-display IGT, which makes sense since the pipecontrol is now flushing the device cache after the render copy. Without EN_L3_RW_CCS_CACHE_FLUSH the test then fails, which is also expected since device cache is now dirty and display engine can't see the writes. 2. Disabling EN_L3_RW_CCS_CACHE_FLUSH, but keeping the driver global invalidation also has no impact on wb-transient-vs-display. This suggests that the global invalidation still works as expected and is flushing the device cache without EN_L3_RW_CCS_CACHE_FLUSH turned on. With that drop EN_L3_RW_CCS_CACHE_FLUSH. This helps some workloads since we no longer flush the device cache between submissions as part of pipecontrol. Edit: We now also have clarification from HW side that BSpec was indeed wrong here. v2: - Rebase and update commit message.

2024-10-08drm/xe/guc: Plumb GuC-capture into dev coredumpZhanjun Dong
When we decide to kill a job, (from guc_exec_queue_timedout_job), we could end up with 4 possible scenarios at this starting point of this decision: 1. the guc-captured register-dump is already there. 2. the driver is wedged.mode > 1, so GuC-engine-reset / GuC-err-capture will not happen. 3. the user has started the driver in execlist-submission mode. 4. the guc-captured register-dump is not ready yet so we force GuC to kill that context now, but: A. we don't know yet if GuC will be successful on the engine-reset and get the guc-err-capture, else kmd will do a manual reset later OR B. guc will be successful and we will get a guc-err-capture shortly. So to accomdate the scenarios of 2 and 4A, we will need to do a manual KMD capture first(which is not be reliable in guc-submission mode) and decide later if we need to use that for the cases of 2 or 4A. So this flow is part of the implementation for this patch. Provide xe_guc_capture_get_reg_desc_list to get the register dscriptor list. Add manual capture by read from hw engine if GuC capture is not ready. If it becomes ready at later time, GuC sourced data will be used. Although there may only be a small delay between (1) the check for whether guc-err-capture is available at the start of guc_exec_queue_timedout_job and (2) the decision on using a valid guc-err-capture or manual-capture, lets not take any chances and lock the matching node down so it doesn't get re-claimed if GuC-Err-Capture subsystem is running out of pre-cached nodes.

2024-10-08drm/xe/guc: Extract GuC error capture listsZhanjun Dong
Upon the G2H Notify-Err-Capture event, parse through the GuC Log Buffer (error-capture-subregion) and generate one or more capture-nodes. A single node represents a single "engine- instance-capture-dump" and contains at least 3 register lists: global, engine-class and engine-instance. An internal link list is maintained to store one or more nodes. Because the link-list node generation happen before the call to devcoredump, duplicate global and engine-class register lists for each engine-instance register dump if we find dependent-engine resets in a engine-capture-group. To avoid dynamically allocate the output nodes during gt reset, pre-allocate a fixed number of empty nodes up front (at the time of ADS registration) that we can consume from or return to an internal cached list of nodes.
