2024-12-22drm/msm/dp: drop msm_dp_panel_dump_regs() and msm_dp_catalog_dump_regs()Dmitry Baryshkov
The msm_dp_panel_dump_regs() and msm_dp_catalog_dump_regs() are not called anywhere. If there is a necessity to dump registers, the snapshotting should be used instead. Drop these two functions.

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.

2024-11-02drm/msm/dpu: move scaling limitations out of the hw_catalogDmitry Baryshkov
Max upscale / downscale factors are constant between platforms. In preparation to adding support for virtual planes and allocating SSPP blocks on demand move max scaling factors out of the HW catalog and handle them in the dpu_plane directly. If any of the scaling blocks gets different limitations, this will have to be handled separately, after the plane refactoring.

2024-10-31drm/msm/dpu: cast crtc_clk calculation to u64 in _dpu_core_perf_calc_clk()Zichen Xie
There may be a potential integer overflow issue in _dpu_core_perf_calc_clk(). crtc_clk is defined as u64, while mode->vtotal, mode->hdisplay, and drm_mode_vrefresh(mode) are defined as a smaller data type. The result of the calculation will be limited to "int" in this case without correct casting. In screen with high resolution and high refresh rate, integer overflow may happen. So, we recommend adding an extra cast to prevent potential integer overflow.

2024-10-31drm/msm/dp: prefix all symbols with msm_dp_Dmitry Baryshkov
For historical reasons a lot of symbols in the MSM DisplayPort driver used the generic dp_ prefix. Perform a mass-rename of those symbols to use msm_dp prefix. Basically this is a result of the following script: sed drivers/gpu/drm/msm/dp/* -i -e 's/\<dp_/msm_dp_/g' sed drivers/gpu/drm/msm/dp/* -i -e 's/"msm_dp_/"dp_/g' sed drivers/gpu/drm/msm/dp/* -i -e 's/msm_\(dp_sdp_header\|dp_sdp\)\>/\1/g' Yes, this also results in renaming of several struct fields in addition to renaming the structs and functions, but I think the simple solution is better than the more complex one.

Add a debugfs interface for exercising the various test modes supported by the DisplayPort controller. This allows performing compliance testing, or performing signal integrity measurements on a failing link. At the moment, we do not support sink-driven link quality testing, although such support would be fairly easy to add. Additionally, add some debugfs files for ignoring AUX errors and HPD events, as this can allow testing with equipment that cannot emulate a DPRX.
