drm/msm/dpu: stop using raw IRQ indices in the kernel output In preparation to reworking IRQ indcies, stop using raw IRQ indices in kernel output (both printk and debugfs). Instead use a pair of register index and bit. This corresponds closer to the values in HW catalog.

drm/msm/dpu: retrieve DSI DSC struct through priv->dsi[0] Currently struct drm_dsc_config for DSI is populated at display setup during system boot up. This mechanism works fine with embedded display but not for pluggable displays as the struct drm_dsc_config will become stale once external display is unplugged. In preparation of adding support for DP DSC support move storing of DSI DSC struct to atomic_enable() so that same mechanism will work for both embedded display and pluggable displays.

drm/msm/dpu: Increment vsync_cnt before waking up userspace The 'vsync_cnt' is used to count the number of frames for a crtc. Unfortunately, we increment the count after waking up userspace via dpu_crtc_vblank_callback() calling drm_crtc_handle_vblank(). drm_crtc_handle_vblank() wakes up userspace processes that have called drm_wait_vblank_ioctl(), and if that ioctl is expecting the count to increase it won't. Increment the count before calling into the drm APIs so that we don't have to worry about ordering the increment with anything else in drm. This fixes a software video decode test that fails to see frame counts increase on Trogdor boards.

drm/msm/disp/dpu1: Add support for DSC in topology For DSC to work we typically need a 2,2,1 configuration. This should suffice for resolutions up to 4k. For more resolutions like 8k this won't work. Also, it is better to use 2 LMs and DSC instances as half width results in lesser power consumption as compared to single LM, DSC at full width. The panel has been tested only with 2,2,1 configuration, so for now we blindly create 2,2,1 topology when DSC is enabled Co-developed-by: Abhinav Kumar <quic_abhinavk@quicinc.com> Signed-off-by: Abhinav Kumar <quic_abhinavk@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Signed-off-by: Vinod Koul <vkoul@kernel.org> Patchwork: https://patchwork.freedesktop.org/patch/480925/ Link: https://lore.kernel.org/r/20220406094031.1027376-11-vkoul@kernel.org Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

drm/msm/dpu: revise timing engine programming to support widebus feature Widebus feature will transmit two pixel data per pixel clock to interface. Timing engine provides driving force for this purpose. This patch base on HPG (Hardware Programming Guide) to revise timing engine register setting to accommodate both widebus and non widebus application. Also horizontal width parameters need to be reduced by half since two pixel data are clocked out per pixel clock when widebus feature enabled. Widebus can be enabled individually at DP. However at DSI, widebus have to be enabled along with DSC to achieve pixel clock rate be scaled down with same ratio as compression ratio when 10 bits per source component. Therefore this patch add no supports of DSI related widebus and compression. Changes in v2: -- remove compression related code from timing -- remove op_info from struct msm_drm_private -- remove unnecessary wide_bus_en variables -- pass wide_bus_en into timing configuration by struct msm_dp Changes in v3: -- split patch into 3 patches Changes in v4: -- rework timing engine to not interfere with dsi/hdmi -- cover both widebus and compression Changes in v5: -- remove supports of DSI widebus and compression Changes in v7: -- split this patch into 3 patches -- add Tested-by Changes in v8: -- move new registers writes under DATA_HCTL_EN features check.

drm/msm/dp: Support up to 3 DP controllers Based on the removal of the g_dp_display and the movement of the priv->dp lookup into the DP code it's now possible to have multiple DP instances. In line with the other controllers in the MSM driver, introduce a per-compatible list of base addresses which is used to resolve the "instance id" for the given DP controller. This instance id is used as index in the priv->dp[] array. Then extend the initialization code to initialize struct drm_encoder for each of the registered priv->dp[] and update the logic for associating each struct msm_dp with the struct dpu_encoder_virt. A new enum is introduced to document the connection between the instances referenced in the dpu_intf_cfg array and the controllers in the DP driver and sc7180 is updated. Lastly, bump the number of struct msm_dp instances carries by priv->dp to 3, the currently known maximum number of controllers found in a Qualcomm SoC.

To enable vblank_disable_immediate flag the underlying KMS driver needs to support high precision vblank timestamping and also a reliable way of providing vblank counter which is incrementing at the leading edge of vblank. This patch also brings in changes to support vblank_disable_immediate requirement in dpu driver. Changes in v1: - Specify reason to add vblank timestamp support. (Rob). - Add changes to provide vblank counter from dpu driver. Changes in v2: - Fix warn stack reported by Rob Clark with v2 patch. Changes in v3: - Move back to HW frame counter (Rob). Changes in v4: - Frame count mismatch was causing a DRM WARN stack spew. DPU HW will increment the frame count at the end of the sync, where as vblank will be triggered at the fetch_start counter which is calculated as v_total - vfp. This is to start fetching early for panels with low vbp w.r.t hw latency lines. Add logic to detect the line count if it falls between vactive and v_total then return incremented frame count value.

drm/msm/dpu: Fix reservation failures in modeset In TEST_ONLY commit, rm global_state will duplicate the object and request for new reservations, once they pass then the new state will be swapped with the old and will be available for the Atomic Commit. This patch fixes some of missing links in the resource reservation sequence mentioned above. 1) Creation of duplicate state in test_only commit (Rob) 2) Allocate and release the resources on every modeset. 3) Avoid allocation only when active is false. In a modeset operation, swap state happens well before disable. Hence clearing reservations in disable will cause failures in modeset enable. Allow reservations to be cleared/allocated before swap, such that only newly committed resources are pushed to HW. Changes in v1: - Move the rm release to atomic_check. - Ensure resource allocation and free happens when active is not changed i.e only when mode is changed.(Rob) Changes in v2: - Handle dpu_kms_get_global_state API failure as it may return EDEADLK (swboyd).

This removes broken dpu_hw_reset_ubwc, which doesn't work because the "force blk offset to zero to access beginning of register region" hack is copied from downstream, where mapped region starts 0x1000 below what is used in the upstream driver.

drm/msm: dpu: Don't set frame_busy_mask for async updates The frame_busy mask is used in frame_done event handling, which is not invoked for async commits. So an async commit will leave the frame_busy mask populated after it completes and future commits will start with the busy mask incorrect. This showed up on disable after cursor move. I was hitting the "this should not happen" comment in the frame event worker since frame_busy was set, we queued the event, but there were no frames pending (since async also doesn't set that).

drm/msm: dpu: Don't queue the frame_done watchdog for cursor In the case of an async/cursor update, we don't wait for the frame_done event, which means handle_frame_done is never called, and the frame_done watchdog isn't canceled. Currently, this results in a frame_done timeout every time the cursor moves without a synchronous frame following it up before the timeout expires. Since we don't wait for frame_done, and don't handle it, we shouldn't modify the watchdog.

drm/msm: dpu: Untangle frame_done timeout units There exists a bunch of confusion as to what the actual units of frame_done is: - The definition states it's in # of frames - CRTC treats it like it's ms - frame_done_timeout comment thinks it's Hz, but it stores ms - frame_done timer is setup such that it _should_ be in frames, but the timeout is super long So this patch tries to interpret what the driver really wants. I've de-centralized the #define since the consumers are expecting different units. For crtc, we just use 60ms since that's what it was doing before. Perhaps we could get fancy and scale with vrefresh, but that's for another time. For encoder, fix the comments and rename frame_done_timeout so it's obvious what the units are. In practice, frame_done_timeout is really just checked against 0 || !0, which I guess is why the units being wrong didn't matter. I've also dropped the timeout from the previous 60 frames to 5. That seems like more than enough time to give up on a frame, and my guess is that no one intended for the timeout to _actually_ be 60 frames.

drm: Split out drm_probe_helper.h Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

drm/msm: dpu: Separate crtc assignment from vblank enable Instead of assigning/clearing the crtc on vblank enable/disable, we can just assign and clear the crtc on modeset. That allows us to just toggle the encoder's vblank interrupts on vblank_enable. So why is this important? Previously the driver was using the legacy pointers to assign/clear the crtc. Legacy pointers are cleared _after_ disabling the hardware, so the legacy pointer was valid during vblank_disable, but that's not something we should rely on. Instead of relying on the core ordering the legacy pointer assignments just so, we'll assign the crtc in dpu_crtc enable/disable. This is the only place that mapping can change, so we're covered there. We're also taking advantage of drm_crtc_vblank_on/off. By using this, we ensure that vblank_enable/disable can never be called while the crtc is off (which means the assigned crtc will always be valid). As such, we don't need to use modeset locks or the crtc_lock in the vblank_enable/disable routine to be sure state is consistent. ...I think.

drm/msm: dpu: Move crtc runtime resume to encoder The crtc runtime resume doesn't actually operate on the crtc, but rather its encoders. The problem with this is that we need to inspect the crtc state to get the currently connected encoders. Since runtime resume isn't guaranteed to be called while holding the modeset locks (although it sometimes is), this presents a race condition. Now that we have ->enabled on the virtual encoders, and a lock to protect it, just call resume on each encoder and only restore the ones that are enabled.

drm/msm/dpu: iterate for assigned hw ctl in virtual encoder In virtual encoder modeset, DPU makes RM request to assign hw blocks for the display. It is also expected in modeset to iterate and associate the physical encoders with their relevant hw blocks. Ping pong blocks are already handled here but hw ctl blocks are not. This change moves the hw_ctl iteration and mapping from physical encoder to virtual encoder. changes in v4: - Fix hw_ctl initialization (Sean) changes in v5: - Update commit text with details on why the change is needed (Sean) Signed-off-by: Jeykumar Sankaran <jsanka@codeaurora.org> Signed-off-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

drm/msm/dpu: remove debugfs support for misr MISR support is the debug feature present in Snapdragon chipsets. At the layer mixer and interfaces, MISR algorithm can generate CRC signatures of the pixel data which can be used for validating the frames generated. Since there are no clients for this feature, strip down the support from the driver. changes in v4: - changed introduced in the series changes in v5: - update commit text with the need for the change(Sean) Signed-off-by: Jeykumar Sankaran <jsanka@codeaurora.org> Signed-off-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

drm/msm: Add SDM845 DPU support 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>
