2018-10-04drm/msm: Replace drm_dev_unref with drm_dev_putThomas Zimmermann1-4/+4
This patch unifies the naming of DRM functions for reference counting of struct drm_device. The resulting code is more aligned with the rest of the Linux kernel interfaces. Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Signed-off-by: Rob Clark <robdclark@gmail.com>
2018-08-11drm/msm: Add a helper function to parse clock namesJordan Crouse1-0/+57
Add a helper function to parse the clock names and set up the bulk data so we can take advantage of the bulk clock functions instead of rolling our own.

2018-07-26drm/msm: Add SDM845 DPU supportJeykumar Sankaran1-11/+124
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.

2017-10-28drm/msm: Support multiple ringbuffersJordan Crouse1-6/+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.

2017-10-28drm/msm: Add per-instance submit queuesJordan Crouse1-8/+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>
2017-10-28drm/msm/adreno: load gpu at probe/bind timeRob Clark1-10/+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.

2017-08-02drm/msm/mdp5: Set up runtime PM for MDSSArchit Taneja1-0/+29
MDSS represents the top level wrapper that contains MDP5, DSI, HDMI and other sub-blocks. W.r.t device heirarchy, it's the parent of all these devices. The power domain of this device is actually tied to the GDSC hw. When any sub-device enables its PD, MDSS's PD is also enabled. The suspend/resume ops enable the top level clocks that end at the MDSS boundary. For now, we're letting them all be optional, since the child devices anyway hold a ref to these clocks. Until now, we'd called a runtime_get() during probe, which ensured that the GDSC was always on. Now that we've set up runtime PM for the children devices, we can get rid of this hack. Note: that the MDSS device is the platform_device in msm_drv.c. The msm_runtime_suspend/resume ops call the funcs that enable/disable the top level MDSS clocks. This is different from MDP4, where the platform device created in msm_drv.c represents MDP4 itself. It would have been nicer to hide these differences by adding new kms funcs, but runtime PM needs to be enabled before kms is set up (i.e, msm_kms_init is called).

2017-06-17drm/msm: Separate locking of buffer resources from struct_mutexSushmita Susheelendra1-0/+1
Buffer object specific resources like pages, domains, sg list need not be protected with struct_mutex. They can be protected with a buffer object level lock. This simplifies locking and makes it easier to avoid potential recursive locking scenarios for SVM involving mmap_sem and struct_mutex. This also removes unnecessary serialization when creating buffer objects, and also between buffer object creation and GPU command submission.

drm-next On the userspace side, all the basics are working, and most of glmark2 is working. I've been working through deqp, and I've got a couple more things to fix (but we've gone from 70% to 80+% pass in last day, and current deqp run that is going should pick up another 5-10%). I expect to push the mesa patches today or tomorrow. There are a couple more a5xx related patches to take the gpu out of secure mode (for the devices that come up in secure mode, like the hw I have), but those depend on an scm patch that would come in through another tree. If that can land in the next day or two, there might be a second late pull request for drm/msm. In addition to the new-shiny, there have also been a lot of overlay/ plane related fixes for issues found using drm-hwc2 (in the process of testing/debugging the atomic/kms fence patches), resulting in rework to assign hwpipes to kms planes dynamically (as part of global atomic state) and also handling SMP (fifo) block allocation atomically as part of the ->atomic_check() step. All those patches should also help out atomic weston (when those patches eventually land). * 'msm-next' of git://people.freedesktop.org/~robclark/linux: (36 commits) drm/msm: gpu: Add support for the GPMU drm/msm: gpu: Add A5XX target support drm/msm: Disable interrupts during init drm/msm: Remove 'src_clk' from adreno configuration drm/msm: gpu: Add OUT_TYPE4 and OUT_TYPE7 drm/msm: Add adreno_gpu_write64() drm/msm: gpu Add new gpu register read/write functions drm/msm: gpu: Return error on hw_init failure drm/msm: gpu: Cut down the list of "generic" registers to the ones we use drm/msm: update generated headers drm/msm/adreno: move scratch register dumping to per-gen code drm/msm/rd: support for 64b iova drm/msm: convert iova to 64b drm/msm: set dma_mask properly drm/msm: Remove bad calls to of_node_put() drm/msm/mdp5: move LM bounds check into plane->atomic_check() drm/msm/mdp5: dump smp state on errors too drm/msm/mdp5: add debugfs to show smp block status drm/msm/mdp5: handle SMP block allocations "atomically" drm/msm/mdp5: dynamically assign hw pipes to planes ...

2016-11-27drm/msm: set dma_mask properlyRob Clark1-1/+7
Previous value really only made sense on armv7 without LPAE. Everything that supports more than 4g of memory also has iommu's that can map anything. Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-11-27drm/msm: Remove bad calls to of_node_put()Archit Taneja1-7/+2
In add_components_mdp, we parse the endpoints in MDP output ports using the helper for_each_endpoint_of_node(). Our function calls of_node_put() on the endpoint node before we iterate over the next one. This is already done by the helper, and results in trying to decrement the refcount twice. Remove the extra of_node_put calls. This fixes warnings seen when we try to insert the driver as a module on IFC6410.

2016-11-27drm/msm: support multiple address spacesRob Clark1-4/+5
We can have various combinations of 64b and 32b address space, ie. 64b CPU but 32b display and gpu, or 64b CPU and GPU but 32b display. So best to decouple the device iova's from mmap offset. Signed-off-by: Rob Clark <robdclark@gmail.com>

2016-11-04drm/msm: Fix error handling crashes seen when VRAM allocation failsArchit Taneja1-1/+1
If VRAM allocation fails, the error handling path crashes in msm_drm_uninit(). The following changes are made to fix this: msm_gem_shrinker_cleanup() is fixed to unregister the shrinker only if it was init-ed in the first place. Before calling kms->funcs->destroy(), we check if kms->funcs is also non-NULL. This is needed for MDP5, since during msm_drm_int(), priv->kms becomes non-NULL early, but msm_kms_init() is called on it only later in mdp5_kms_init().
