* drm/msm: Pass the MMU domain index in struct msm_file_privateJordan Crouse2019-06-181-0/+2
| | | | | | | | | Pass the index of the MMU domain in struct msm_file_private instead of assuming gpu->id throughout the submit path. This clears the way to change ctx->aspace to a per-instance pagetable. Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rob Clark <robdclark@chromium.org>

|\ | | | | | | | | | | | | | | | | | | | | | | | | https://gitlab.freedesktop.org/drm/msm into drm-next This time around it is a bunch of cleanup and fixes, expanding gpu "zap" shader support (so we can take the GPU out of secure mode on boot) to a6xx, and small UABI extension to support robustness (see mesa MR 673).

| * drm/msm: Implement .gem_free_object_unlockedKristian H. Kristensen2019-04-191-1/+4
| | | | | | | | | | | | | | | | | | | | | | We use a llist and a worker to delay the object cleanup. This avoids taking mmap_sem and struct_mutex in the wrong order when calling drm_gem_object_put_unlocked() from drm_gem_mmap(). Fixes lockdep problem with copy_from_user() in msm_ioctl_gem_submit().

| * drm/msm/gpu: Add submit queue queriesJordan Crouse2019-04-191-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

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.

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.

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.

* drm/msm/mdp5: subclass msm_mdss for mdp5Rajesh Yadav2018-07-261-7/+15
| | | | | | | | | | | | | | | | | | | | | | | | | SoCs having mdp5 or dpu have identical tree like device hierarchy where MDSS top level wrapper manages common power resources for all child devices. Subclass msm_mdss so that msm_mdss includes common defines and mdp5/dpu mdss derivations to include any extensions. Add mdss helper interface (msm_mdss_funcs) to msm_mdss base for mdp5/dpu mdss specific implementation calls. This change subclasses msm_mdss for mdp5, dpu specific changes will be done separately.

* drm/msm: Support multiple ringbuffersJordan Crouse2017-10-281-6/+17
| | | | | | | | | | | | | | | | | | | | 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.

* drm/msm: Add per-instance submit queuesJordan Crouse2017-10-281-8/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the behavior of a command stream is provided by the user application during submission and the application is expected to internally maintain the settings for each 'context' or 'rendering queue' and specify the correct ones. This works okay for simple cases but as applications become more complex we will want to set context specific flags and do various permission checks to allow certain contexts to enable additional privileges. Add kernel-side submit queues to be analogous to 'contexts' or 'rendering queues' on the application side. Each file descriptor instance will maintain its own list of queues. Queues cannot be shared between file descriptors. For backwards compatibility context id '0' is defined as a default context specifying no priority and no special flags. This is intended to be the usual configuration for 99% of applications so that a garden variety application can function correctly without creating a queue. Only those applications requiring the specific benefit of different queues need create one. Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
* drm/msm/adreno: load gpu at probe/bind timeRob Clark2017-10-281-10/+0
| | | | | | | | | | | | | | | Previously, in an effort to defer initializing the gpu until firmware was available (ie. rootfs mounted), the gpu was not loaded at when the subdevice was bound. Which resulted that clks/etc were requested in a place that devm couldn't really help unwind if something failed. Instead move request_firmware() to gpu->hw_init() and construct the gpu earlier in adreno_bind(). To avoid the rest of the driver needing to be aware of a gpu that hasn't managed to load firmware and hw_init() yet, stash the gpu ptr in the adreno device's drvdata, and don't set priv->gpu() until hw_init() succeeds.
