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.

2024-12-01Get rid of 'remove_new' relic from platform driver structLinus Torvalds
The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Add X1E Devkit to the list of devices that has functional EFI variable access through the uefisecapp. Flip the "manual slice configuration quirk" in the Qualcomm LLCC driver, as this only applies to a single platform, and introduce support for QCS8300, QCS615, SAR2130P, and SAR1130P.

2024-11-11drm/msm/adreno: Setup SMMU aparture for per-process page tableBjorn Andersson
Support for per-process page tables requires the SMMU aparture to be setup such that the GPU can make updates with the SMMU. On some targets this is done statically in firmware, on others it's expected to be requested in runtime by the driver, through a SCM call. One place where configuration is expected to be done dynamically is the QCS6490 rb3gen2. The downstream driver does this unconditioanlly on any A6xx and newer, so follow suite and make the call.

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.
