[ Upstream commit 06dd5d86c6aef1c7609ca3a5ffa4097e475e2213 ] Somehow, possibly as a result of rebase gone badly, setting nr_indexed_regs for pre-a650 a6xx devices lost the setting of nr_indexed_regs, resulting in values getting snapshot, but omitted from the devcoredump.

2025-04-10drm/msm/dsi: Set PHY usescase (and mode) before registering DSI hostMarijn Suijten1-11/+21
[ Upstream commit 660c396c98c061f9696bebacc178b74072e80054 ] Ordering issues here cause an uninitialized (default STANDALONE) usecase to be programmed (which appears to be a MUX) in some cases when msm_dsi_host_register() is called, leading to the slave PLL in bonded-DSI mode to source from a clock parent (dsi1vco) that is off. This should seemingly not be a problem as the actual dispcc clocks from DSI1 that are muxed in the clock tree of DSI0 are way further down, this bit still seems to have an effect on them somehow and causes the right side of the panel controlled by DSI1 to not function. In an ideal world this code is refactored to no longer have such error-prone calls "across subsystems", and instead model the "PLL src" register field as a regular mux so that changing the clock parents programmatically or in DTS via `assigned-clock-parents` has the desired effect. But for the avid reader, the clocks that we *are* muxing into DSI0's tree are way further down, so if this bit turns out to be a simple mux between dsiXvco and out_div, that shouldn't have any effect as this whole tree is off anyway.

2025-04-10drm/msm/dsi: Use existing per-interface slice count in DSC timingMarijn Suijten2-15/+4
[ Upstream commit 14ad809ceb66d0874cbe4bd5ca9edf0de8d9ad96 ] When configuring the timing of DSI hosts (interfaces) in dsi_timing_setup() all values written to registers are taking bonded-mode into account by dividing the original mode width by 2 (half the data is sent over each of the two DSI hosts), but the full width instead of the interface width is passed as hdisplay parameter to dsi_update_dsc_timing(). Currently only msm_dsc_get_slices_per_intf() is called within dsi_update_dsc_timing() with the `hdisplay` argument which clearly documents that it wants the width of a single interface (which, again, in bonded DSI mode is half the total width of the mode) resulting in all subsequent values to be completely off. However, as soon as we start to pass the halved hdisplay into dsi_update_dsc_timing() we might as well discard msm_dsc_get_slices_per_intf() since the value it calculates is already available in dsc->slice_count which is per-interface by the current design of MSM DPU/DSI implementations and their use of the DRM DSC helpers.

2025-02-27drm/msm/dp: account for widebus and yuv420 during mode validationAbhinav Kumar2-6/+10
commit df9cf852ca3099feb8fed781bdd5d3863af001c8 upstream. Widebus allows the DP controller to operate in 2 pixel per clock mode. The mode validation logic validates the mode->clock against the max DP pixel clock. However the max DP pixel clock limit assumes widebus is already enabled. Adjust the mode validation logic to only compare the adjusted pixel clock which accounts for widebus against the max DP pixel clock. Also fix the mode validation logic for YUV420 modes as in that case as well, only half the pixel clock is needed.

2025-02-27drm/msm/dpu: Don't leak bits_per_component into random DSC_ENC fieldsMarijn Suijten1-1/+2
[ Upstream commit 144429831f447223253a0e4376489f84ff37d1a7 ] What used to be the input_10_bits boolean - feeding into the lowest bit of DSC_ENC - on MSM downstream turned into an accidental OR with the full bits_per_component number when it was ported to the upstream kernel. On typical bpc=8 setups we don't notice this because line_buf_depth is always an odd value (it contains bpc+1) and will also set the 4th bit after left-shifting by 3 (hence this |= bits_per_component is a no-op). Now that guards are being removed to allow more bits_per_component values besides 8 (possible since commit 49fd30a7153b ("drm/msm/dsi: use DRM DSC helpers for DSC setup")), a bpc of 10 will instead clash with the 5th bit which is convert_rgb. This is "fortunately" also always set to true by MSM's dsi_populate_dsc_params() already, but once a bpc of 12 starts being used it'll write into simple_422 which is normally false. To solve all these overlaps, simply replicate downstream code and only set this lowest bit if bits_per_component is equal to 10. It is unclear why DSC requires this only for bpc=10 but not bpc=12, and also notice that this lowest bit wasn't set previously despite having a panel and patch on the list using it without any mentioned issues.

2024-12-02Get rid of 'remove_new' relic from platform driver structLinus Torvalds10-10/+10
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>

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.

2024-11-03drm/msm/dpu: rework documentation commentsDmitry Baryshkov47-543/+502
Unfortunately the tooling doesn't check documents placed before funciton prototypes. Such comments frequently become outdated, miss several params, etc. Move documentation for the functions to be placed before the actual function body, allowing 'make W=1' to actually check these comments and report an error.

2024-11-02drm/msm/mdss: use register definitions instead of hand-coding themDmitry Baryshkov2-20/+21
Move existing register definitions to mdss.xml and use generated defines for registers access instead of hand-coding everything in the source file.

2024-11-02drm/msm/dpu: move rot90 checking to dpu_plane_atomic_check_sspp()Dmitry Baryshkov3-28/+31
Move a call to dpu_plane_check_inline_rotation() to the dpu_plane_atomic_check_sspp() function, so that the rot90 constraints are checked for both SSPP blocks. Also move rotation field from struct dpu_plane_state to struct dpu_sw_pipe_cfg.

Split dpu_plane_atomic_check() function into two pieces: dpu_plane_atomic_check_nosspp() performing generic checks on the pstate, without touching the associated SSPP blocks, and dpu_plane_atomic_check_sspp(), which takes into account used SSPPs.

2024-11-02drm/msm/dpu: move scaling limitations out of the hw_catalogDmitry Baryshkov3-23/+13
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.

2024-11-02drm/msm/dpu: drop virt_formats from SSPP subblock configurationDmitry Baryshkov2-16/+0
The virt_formats / virt_num_formats are not used by the current driver and are not going to be used in future since formats for virtual planes are handled in a different way, by forbidding unsupported combinations during atomic_check. Drop those fields now.

In preparation for virtualized planes support, move pstate->pipe initialization from dpu_plane_reset() to dpu_plane_atomic_check().
