2024-12-16drm/i915/mst: use intel_dp_compute_config_limits() for DP MSTJani Nikula
There's a lot of duplication between mst_stream_compute_config_limits() and intel_dp_compute_config_limits(). Adjust the latter to suit the needs of the former, and use the same function for both. This reduces duplication and highlights the differences for SST and MST and UHBR. Remove the kernel-doc for intel_dp_compute_config_link_bpp_limits() which now becomes static.

The warning triggers from the legacy fallback stub. That warning is bogus as the PCI/MSI layer knows whether a PCI/MSI parent domain is associated with the device or not. There is a check for MSI-X, which has a legacy assumption. But that legacy fallback assumption is only valid when legacy support is enabled, but otherwise the check should simply return -ENOTSUPP. Loongarch tripped over the same problem and blindly enabled legacy support without implementing the legacy fallbacks. There are weak implementations which return an error, so the problem was papered over. Correct pci_msi_domain_supports() to evaluate the legacy mode and add the missing supported check into the MSI enable path to complete it.

2024-12-16thunderbolt: Improve redrive mode handlingMika Westerberg
When USB-C monitor is connected directly to Intel Barlow Ridge host, it goes into "redrive" mode that basically routes the DisplayPort signals directly from the GPU to the USB-C monitor without any tunneling needed. However, the host router must be powered on for this to work. Aaron reported that there are a couple of cases where this will not work with the current code: - Booting with USB-C monitor plugged in. - Plugging in USB-C monitor when the host router is in sleep state (runtime suspended). - Plugging in USB-C device while the system is in system sleep state. In all these cases once the host router is runtime suspended the picture on the connected USB-C display disappears too. This is certainly not what the user expected. For this reason improve the redrive mode handling to keep the host router from runtime suspending when detect that any of the above cases is happening.

The existing linked list based implementation of how ts tags are assigned and managed is unsafe against concurrency and corner cases: - element addition in tx processing can race against element removal in ts queue completion, - element removal in ts queue completion can race against element removal in device close, - if a large number of frames gets added to tx queue without ts queue completions in between, elements with duplicate tag values can get added.

2024-12-15ionic: no double destroy workqueueShannon Nelson
There are some FW error handling paths that can cause us to try to destroy the workqueue more than once, so let's be sure we're checking for that. The case where this popped up was in an AER event where the handlers got called in such a way that ionic_reset_prepare() and thus ionic_dev_teardown() got called twice in a row. The second time through the workqueue was already destroyed, and destroy_workqueue() choked on the bad wq pointer. We didn't hit this in AER handler testing before because at that time we weren't using a private workqueue. Later we replaced the use of the system workqueue with our own private workqueue but hadn't rerun the AER handler testing since then.

2024-12-15drm/msm/dpu: allow using two SSPP blocks for a single planeDmitry Baryshkov
Virtual wide planes give high amount of flexibility, but it is not always enough: In parallel multirect case only the half of the usual width is supported for tiled formats. Thus the whole width of two tiled multirect rectangles can not be greater than max_linewidth, which is not enough for some platforms/compositors. Another example is as simple as wide YUV plane. YUV planes can not use multirect, so currently they are limited to max_linewidth too. Now that the planes are fully virtualized, add support for allocating two SSPP blocks to drive a single DRM plane. This fixes both mentioned cases and allows all planes to go up to 2*max_linewidth (at the cost of making some of the planes unavailable to the user).

2024-12-15drm/msm/dpu: add support for virtual planesDmitry Baryshkov
Only several SSPP blocks support such features as YUV output or scaling, thus different DRM planes have different features. Properly utilizing all planes requires the attention of the compositor, who should prefer simpler planes to YUV-supporting ones. Otherwise it is very easy to end up in a situation when all featureful planes are already allocated for simple windows, leaving no spare plane for YUV playback. To solve this problem make all planes virtual. Each plane is registered as if it supports all possible features, but then at the runtime during the atomic_check phase the driver selects backing SSPP block for each plane. As the planes are attached to the CRTC and not the encoder, the SSPP blocks are also allocated per CRTC ID (all other resources are currently allocated per encoder ID). This also matches the hardware requirement, where both rectangles of a single SSPP can only be used with the LM pair. Note, this does not provide support for using two different SSPP blocks for a single plane or using two rectangles of an SSPP to drive two planes. Each plane still gets its own SSPP and can utilize either a solo rectangle or both multirect rectangles depending on the resolution. Note #2: By default support for virtual planes is turned off and the driver still uses old code path with preallocated SSPP block for each plane. To enable virtual planes, pass 'msm.dpu_use_virtual_planes=1' kernel parameter.

2024-12-15drm/msm/dpu: filter out too wide modes if no 3dmux is presentAbhinav Kumar
On chipsets such as QCS615, there is no 3dmux present. In such a case, a layer exceeding the max_mixer_width cannot be split, hence cannot be supported. Filter out the modes which exceed the max_mixer_width when there is no 3dmux present. Also, add a check in the dpu_crtc_atomic_check() to return failure for such modes.

2024-12-15drm/rockchip: vop2: Fix the windows switch between different layersAndy Yan
Every layer of vop2 should bind a window, and we also need to make sure that this window is not used by other layer. 0x5 is a reserved layer sel value on rk3568, but it will select Cluster3 on rk3588, configure unused layers to 0x5 will lead alpha blending error on rk3588. When we bind a window from layerM to layerN, we move the old window on layerN to layerM.
