2025-07-04drm/msm: Stop passing vm to msm_framebufferRob Clark
The fb only deals with kms->vm, so make that explicit. This will start letting us refcount the # of times the fb is pinned, so we can only unpin the vma after last user of the fb is done. Having a single reference count really only works if there is only a single vm.

Declaring only XR30 but not AR30 color format support can trigger bugs in userspace. KDE KWin compositor versions prior to 5.27.3 for example prefer 10-bit color formats, rendering a 1cm^2 black box around the cursor due to missing per-pixel alpha-blending.

2019-05-20drm: Remove users of drm_format_num_planesMaxime Ripard
drm_format_num_planes() is basically a lookup in the drm_format_info table plus an access to the num_planes field of the appropriate entry. Most drivers are using this function while having access to the entry already, which means that we will perform an unnecessary lookup. Removing the call to drm_format_num_planes is therefore more efficient. Some drivers will not have access to that entry in the function, but in this case the overhead is minimal (we just have to call drm_format_info() to perform the lookup) and we can even avoid multiple, inefficient lookups in some places that need multiple fields from the drm_format_info structure.

2018-07-26drm/msm: Add SDM845 DPU supportJeykumar Sankaran
SDM845 SoC includes the Mobile Display Sub System (MDSS) which is a top level wrapper consisting of Display Processing Unit (DPU) and display peripheral modules such as Display Serial Interface (DSI) and DisplayPort (DP). MDSS functions essentially as a back-end composition engine. It blends video and graphic images stored in the frame buffers and scans out the composed image to a display sink (over DSI/DP). The following diagram represents hardware blocks for a simple pipeline (two planes are present on a given crtc which is connected to a DSI connector): MDSS +---------------------------------+ | +-----------------------------+ | | | DPU | | | | +--------+ +--------+ | | | | | SSPP | | SSPP | | | | | +----+---+ +----+---+ | | | | | | | | | | +----v-----------v---+ | | | | | Layer Mixer (LM) | | | | | +--------------------+ | | | | +--------------------+ | | | | | PingPong (PP) | | | | | +--------------------+ | | | | +--------------------+ | | | | | INTERFACE (VIDEO) | | | | | +---+----------------+ | | | +------|----------------------+ | | | | | +------|---------------------+ | | | | DISPLAY PERIPHERALS | | | | +---v-+ +-----+ | | | | | DSI | | DP | | | | | +-----+ +-----+ | | | +----------------------------+ | +---------------------------------+ The number of DPU sub-blocks (i.e. SSPPs, LMs, PP blocks and INTFs) depends on SoC capabilities. Overview of DPU sub-blocks: --------------------------- * Source Surface Processor (SSPP): Refers to any of hardware pipes like ViG, DMA etc. Only ViG pipes are capable of performing format conversion, scaling and quality improvement for source surfaces. * Layer Mixer (LM): Blend source surfaces together (in requested zorder) * PingPong (PP): This block controls frame done interrupt output, EOL and EOF generation, overflow/underflow control. * Display interface (INTF): Timing generator and interface connecting the display peripherals. DRM components mapping to DPU architecture: ------------------------------------------ PLANEs maps to SSPPs CRTC maps to LMs Encoder maps to PPs, INTFs Data flow setup: --------------- MDSS hardware can support various data flows (e.g.): - Dual pipe: Output from two LMs combined to single display. - Split display: Output from two LMs connected to two separate interfaces. The hardware capabilities determine the number of concurrent data paths possible. Any control path (i.e. pipeline w/i DPU) can be routed to any of the hardware data paths. A given control path can be triggered, flushed and controlled independently. Changes in v3: - Move msm_media_info.h from uapi to dpu/ subdir - Remove preclose callback dpu (it's handled in core) - Fix kbuild warnings with parent_ops - Remove unused functions from dpu_core_irq - Rename mdss_phys to mdss - Rename mdp_phys address space to mdp - Drop _phys from vbif and regdma binding names Signed-off-by: Abhinav Kumar <abhinavk@codeaurora.org> Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Chandan Uddaraju <chandanu@codeaurora.org> Signed-off-by: Jeykumar Sankaran <jsanka@codeaurora.org> Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rajesh Yadav <ryadav@codeaurora.org> Signed-off-by: Sravanthi Kollukuduru <skolluku@codeaurora.org> Signed-off-by: Sean Paul <seanpaul@chromium.org> [robclark minor rebase] Signed-off-by: Rob Clark <robdclark@gmail.com>
