2019-09-03drm/msm: async commit supportRob Clark1-0/+4
Now that flush/wait/complete is decoupled from the "synchronous" part of atomic commit_tail(), add support to defer flush to a timer that expires shortly before vblank for async commits. In this way, multiple atomic commits (for example, cursor updates) can be coalesced into a single flush at the end of the frame. v2: don't hold lock over ->wait_flush(), to avoid locking interaction that was causing fps drop when combining page flips or non-async atomic commits and lots of legacy cursor updates Signed-off-by: Rob Clark <robdclark@chromium.org> Reviewed-by: Sean Paul <sean@poorly.run>

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: Sam Ravnborg <sam@ravnborg.org> Cc: Rob Clark <robdclark@gmail.com> Cc: Sean Paul <sean@poorly.run> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Jordan Crouse <jcrouse@codeaurora.org> Cc: Jeykumar Sankaran <jsanka@codeaurora.org> Cc: Bruce Wang <bzwang@chromium.org> Cc: Shayenne Moura <shayenneluzmoura@gmail.com> Cc: Mamta Shukla <mamtashukla555@gmail.com> Cc: Jonathan Marek <jonathan@marek.ca> Cc: Carsten Behling <carsten.behling@googlemail.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <maxime.ripard@bootlin.com> Cc: Paul Kocialkowski <paul.kocialkowski@bootlin.com> Cc: Sibi Sankar <sibis@codeaurora.org> Cc: Todor Tomov <todor.tomov@linaro.org> Cc: linux-arm-msm@vger.kernel.org Cc: freedreno@lists.freedesktop.org Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190804065551.GA5211@ravnborg.org

2019-04-19drm/msm/gpu: Add submit queue queriesJordan Crouse1-0/+2
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).

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter1-1/+1
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.

2018-12-11drm/msm: Count how many times iova memory is pinnedJordan Crouse1-2/+6
Add a reference count to track how many times a particular chunk of iova memory is pinned (mapped) in the iomu and add msm_gem_unpin_iova to give up references. It is important to note that msm_gem_unpin_iova replaces msm_gem_put_iova because the new implicit behavior that an assigned iova in a given vma is now valid for the life of the buffer and what we are really focusing on is the use of that iova. For now the unmappings are lazy; once the reference counts go to zero they *COULD* be unmapped dynamically but that will require an outside force such as a shrinker or mm_notifiers. For now, we're just focusing on getting the counting right and setting ourselves up to be ready for the future.

2018-07-26drm/msm: Add SDM845 DPU supportJeykumar Sankaran1-3/+78
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>

2018-06-04drm/msm: Remove msm_commit/worker, use atomic helper commitSean Paul1-4/+0
Moving further towards switching fully to the the atomic helpers, this patch removes the hand-rolled worker nonblock commit code and uses the atomic helpers commit_work model. Changes in v2: - Remove commit_destroy() - Shuffle order of commit_tail calls to further serialize commits - Use stall in swap_state to avoid abandoned events on disable Changes in v3: - Rebased on Archit's private_obj set Changes in v4: - None Signed-off-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2018-06-04drm/msm: Move implicit sync handling to prepare_fbSean Paul1-0/+2
In preparation for moving to atomic helpers, move the implicit sync fence handling out of atomic commit and into the plane->prepare_fb() hook.

2017-12-13drm/msm: fix msm_rd_dump_submit prototypeArnd Bergmann1-1/+2
The prototype of msm_rd_dump_submit() has recently changed. However, we have two declarations of this functions, and the other one remains the old version, leading to this: drivers/gpu/drm/msm/msm_gpu.c: In function 'recover_worker': drivers/gpu/drm/msm/msm_gpu.c:295:23: error: passing argument 1 of 'msm_rd_dump_submit' from incompatible pointer type [-Werror=incompatible-pointer-types] This changes the second one to match the first again.

2017-10-28drm/msm: split rd debugfs fileRob Clark1-2/+3
Split into two instances, the existing $debugfs/rd which continues to dump all submits, and $debugfs/hangrd which will be used to dump just submits that cause gpu hangs (and eventually faults, but that will require some iommu framework enhancements). Signed-off-by: Rob Clark <robdclark@gmail.com>
2017-10-28drm/msm: add special _get_vaddr_active() for cmdstream dumpsRob Clark1-0/+1
Prep work for adding a debugfs file that dumps just submits which trigger hangs/faults. In this case the bo may already be in the MADV_DONTNEED state, but will be still on the active list (since the submit hasn't completed yet). So the normal check that the bo is in the WILLNEED state does not apply. (But of course the bo should definitely not be in the PURGED state!) Signed-off-by: Rob Clark <robdclark@gmail.com>

2017-10-28drm/msm: Implement preemption for A5XX targetsJordan Crouse1-1/+1
Implement preemption for A5XX targets - this allows multiple ringbuffers for different priorities with automatic preemption of a lower priority ringbuffer if a higher one is ready. Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2017-10-28drm/msm: Support multiple ringbuffersJordan Crouse1-3/+5
Add the infrastructure to support the idea of multiple ringbuffers. Assign each ringbuffer an id and use that as an index for the various ring specific operations. The biggest delta is to support legacy fences. Each fence gets its own sequence number but the legacy functions expect to use a unique integer. To handle this we return a unique identifier for each submission but map it to a specific ring/sequence under the covers. Newer users use a dma_fence pointer anyway so they don't care about the actual sequence ID or ring. The actual mechanics for multiple ringbuffers are very target specific so this code just allows for the possibility but still only defines one ringbuffer for each target family.
