2019-09-03drm/msm: async commit supportRob Clark4-1/+210
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 <[email protected]> Reviewed-by: Sean Paul <[email protected]>
2019-09-03drm/msm: split power control from prepare/complete_commitRob Clark5-14/+54

2019-09-03drm/msm: add kms->flush_commit()Rob Clark5-4/+63
Add ->flush_commit(crtc_mask). Currently a no-op, but kms backends should migrate writing flush registers to this hook, so we can decouple pushing updates to hardware, and flushing the updates. Once we add async commit support, the hw updates will be pushed down to the hw synchronously, but flushing the updates will be deferred until as close to vblank as possible, so that multiple updates can be combined in a single frame.

2019-09-03drm/msm/dpu: fix "frame done" timeoutsRob Clark4-33/+38
Previously, dpu_crtc_frame_event_work() would try to aquire all the modeset locks in order to check whether it can release bandwidth. (If we only have cmd-mode display, bandwidth can be released at frame-done time.) The problem with this is that it is also responsible for signalling frame_done_comp, which dpu_crtc_commit_kickoff() waits on if there is already a frame pending. This is called in the msm_atomic_commit_tail() path.. which means that for non-nonblock commits, at least some of the modeset locks are already held. Re-work this scheme to use a reference count to track our need to have clocks enabled. It is incremented for each atomic commit, and decremented in the corresponding frame-done. Additionally, any crtc used in video mode hold an extra reference while they are enabled. The net effect is that we can determine in frame-done whether it is safe to drop bandwidth without needing to aquire any modeset locks.

2019-09-03drm/msm: Use struct_size() helperGustavo A. R. Silva1-2/+2
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct msm_gem_submit { ... struct { ... } bos[0]; }; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(*submit) + ((u64)nr_bos * sizeof(submit->bos[0])) with: struct_size(submit, bos, nr_bos) This code was detected with the help of Coccinelle.

2019-09-03drm/msm/mdp5: Find correct node for creating gem address spaceJeffrey Hugo1-1/+6
Creating the msm gem address space requires a reference to the dev where the iommu is located. The driver currently assumes this is the same as the platform device, which breaks when the iommu is outside of the platform device (ie in the parent). Default to using the platform device, but check to see if that has an iommu reference, and if not, use the parent device instead. This should handle all the various iommu designs for mdp5 supported systems.

2019-09-03drm/msm/hdmi: Convert to use GPIO descriptorsLinus Walleij3-67/+45
This switches the MSM HDMI code to use GPIO descriptors. Normally we would fetch the GPIOs from the device with the flags GPIOD_IN or GPIOD_OUT_[LOW|HIGH] to set up the lines immediately, but since the code seems eager to actively drive the lines high/low when turning HDMI on and off, we just fetch the GPIOs as-is and keep the code explicitly driving them. The old code would try legacy bindings (GPIOs without any "-gpios" suffix) but this has been moved to the gpiolib as a quirk by the previous patch.

The DPU has some kind of idea that it wants to be able to bring up power using GPIO lines. The struct dss_gpio is however completely unused and should this be done, it should be done using the GPIO descriptor framework rather than this API which relies on the global GPIO numberspace. Delete this code before anyone hurt themselves.
