Drop the deprecated drmP.h header file, and trim msm_drv.h to the relevant include files. This resulted in a suprisingly many edits as many files relied on headers included via msm_drv.h. But msm_drv.h is not supposed to carry include files it do not need, so the individual files have to include what extra they needs. v2: - Rebased on top of https://gitlab.freedesktop.org/drm/msm.git msm-next Signed-off-by:

add_gpu_components() adds found GPU nodes from the DT to the match list, regardless of the status of the nodes. This is a problem, because if the nodes are disabled, they should not be on the match list because they will not be matched. This prevents display from initing if a GPU node is defined, but it's status is disabled. Fix this by checking the node's status before adding it to the match list.

If bind fails, we can call msm_drm_uninit before kms elements have been created. In this case, drm_atomic_helper_shutdown will fail since there are no drm objects. Only call drm unregistration and shutdown if drm is registered. Also while we're in here move the workqueue destruction to below component_unbind since components could be actively using the wq during uninit or in their unbind routine. Reviewed-by:

add_display_components() calls of_platform_populate, and we depopluate on pdev remove, but not when probe fails. So if we get a probe deferral in one of the components, we won't depopulate the platform. This causes the core to keep references to devices which should be destroyed, which causes issues when those same devices try to re-initialize on the next probe attempt. I think this is the reason we had issues with the gmu's device-managed resources on deferral (worked around in commit 94e3a17f33a5). Reviewed-by:

Add the capability to query information from a submit queue. The first available parameter is for querying the number of GPU faults (hangs) that can be attributed to the queue. This is useful for implementing context robustness. A user context can regularly query the number of faults to see if it is responsible for any and if so it can invalidate itself. This is also helpful for testing by confirming to the user driver if a particular command stream caused a fault (or not as the case may be). Signed-off-by:

DPU was using one thread per display to dispatch async commits and vblank requests. Since clean up already happened in msm to use the common thread for all the display commits, display threads are only used to cater vblank requests. Since a single thread is sufficient to do the job without any performance hits, use msm workqueue to queue requests. A separate patch is submitted later in this series to remove the display threads altogether. changes in v2: - switch to system wq before removing disp threads (Sean Paul) changes in v3: - none changes in v4: - use msm wq for vblank events changes in v5: - none Signed-off-by:

If a non-legacy driver calls these it's valid to assume there is interrupt support.

When trying to get the display up on my sdm845 board I noticed that the display wouldn't probe if I had the dsi1 node marked as "disabled" even though my board doesn't use dsi1. It looks like the msm code adds all nodes to its list of components even if they are disabled. I believe this doesn't work because all registered components need to come up before we finish probing. Let's do like other DRM code and only add available components. Signed-off-by:

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:
