2025-01-25drm/nouveau: fix the broken marco GSP_MSG_MAX_SIZEZhi Wang
The macro GSP_MSG_MAX_SIZE refers to another macro that doesn't exist. It represents the max GSP message element size. Fix the broken marco so it can be used to replace some magic numbers in the code.

2025-01-24drm/dp_mst: Fix drm RAD printWayne Lin
[Why] The RAD of sideband message printed today is incorrect. For RAD stored within MST branch - If MST branch LCT is 1, it's RAD array is untouched and remained as 0. - If MST branch LCT is larger than 1, use nibble to store the up facing port number in cascaded sequence as illustrated below: u8 RAD[0] = (LCT_2_UFP << 4) | LCT_3_UFP RAD[1] = (LCT_4_UFP << 4) | LCT_5_UFP ... In drm_dp_mst_rad_to_str(), it wrongly to use BIT_MASK(4) to fetch the port number of one nibble. [How] Adjust the code by: - RAD array items are valuable only for LCT >= 1. - Use 0xF as the mask to replace BIT_MASK(4) V2: - Document how RAD is constructed (Imre) V3: - Adjust the comment for rad[] so kdoc formats it properly (Lyude) Fixes: 2f015ec6eab6 ("drm/dp_mst: Add sideband down request tracing + selftests") Cc: Imre Deak <imre.deak@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Harry Wentland <hwentlan@amd.com> Cc: Lyude Paul <lyude@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.com> Signed-off-by: Wayne Lin <Wayne.Lin@amd.com> Signed-off-by: Lyude Paul <lyude@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250113091100.3314533-2-Wayne.Lin@amd.com

Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over syscon_regmap_lookup_by_phandle() combined with getting the syscon argument. Except simpler code this annotates within one line that given phandle has arguments, so grepping for code would be easier. There is also no real benefit in printing errors on missing syscon argument, because this is done just too late: runtime check on static/build-time data.

Remove the call to ast_dp_launch() from ast_detect_tx_chip() and perform it unconditionally in ast_post_gpu(). Also add error handling: the detection code apparently used ast_dp_launch() to test for a working ASTDP, falling back to VGA on errors.

2025-01-20drm/sched: Add helper to check job dependenciesTvrtko Ursulin
Lets isolate scheduler internals from drivers such as pvr which currently walks the dependency array to look for fences.

2025-01-19drm/vc4: Remove BOs seqnosMaíra Canal
`bo->seqno`, `bo->write_seqno`, and `exec->bin_dep_seqno` are leftovers from a time when VC4 didn't support DMA Reservation Objects. Before DMA Resv was introduced, tracking the correspondence between BOs and jobs through the job's seqno made sense. However, this is no longer needed, as VC4 now supports DMA Reservation Objects and attaches the "job done" fence to the BOs. Therefore, remove the BOs seqnos in favor of using DMA Resv Objects.

2025-01-19drm/vc4: Use DMA Resv to implement VC4 wait BO IOCTLMaíra Canal
Since the BOs used by VC4 have DMA Reservation Objects attached to them, waiting for seqnos to check BO availability is unnecessary. Instead, `drm_gem_dma_resv_wait()` can be used.

2025-01-19drm/vc4: Use DRM Execution ContextsMaíra Canal
VC4 has internal copies of `drm_gem_lock_reservations()` and `drm_gem_unlock_reservations()` within the driver. Ideally, these hard-coded functions should be replaced with the generic functions provided by DRM common code. However, instead of using the DRM GEM functions to (un)lock reservations, transition to the new DRM Execution Contexts API.

2025-01-19drm/virtio: Don't return error if virtio-gpu PCI dev is not foundVivek Kasireddy
While fixing a shared VGA resource ownership issue, commit 5dd8b536bbda ("drm/virtio: Lock the VGA resources during initialization") wrongly assumed that there is always a PCI device associated with virtio-gpu and it would return error if this device is not found during init. This is incorrect, as virtio-gpu can be operated in MMIO mode (M68K) where a PCI device would probably not be created for it. Therefore, fix this issue by not erroring out if the associated PCI device is not found during initialization.

2025-01-17accel/qaic: Change aic100_image_table definitionYoussef Samir
aic100_image_table is currently defined as a "const char *" array, this can potentially lead to the accidental modification of the pointers inside. Also, checkpatch.pl gives a warning about it. Change the type to a "const char * const" array to make the pointers immutable, preventing accidental modification of the images' paths.

2025-01-16drm/sched: Remove weak paused submission checksTvrtko Ursulin
There is no need to check the boolean in the work item's prologues since the boolean can be set at any later time anyway. The helper which pauses submission sets it and synchronously cancels the work and helpers which queue the work check for the flag so all should be good.
