2019-09-03drm/msm/dpu: add real wait_for_commit_done()Rob Clark
Just waiting for next vblank isn't ideal.. we should really be looking at the hw FLUSH register value to know if there is still an in-progress flush without stalling unnecessarily when there is no pending flush.

It attempted to avoid fps drops in the presence of cursor updates. But it is racing, and can result in hw updates after flush before vblank, which leads to underruns.

2019-09-03drm/msm/dpu: fix "frame done" timeoutsRob Clark
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/mdp5: Find correct node for creating gem address spaceJeffrey Hugo
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/dpu: Drop unused GPIO codeLinus Walleij
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. The inclusion of <linux/gpio.h> was abused to get some OF and IRQ headers implicitly included into the DPU utilities, make these includes explicit and push them down into the actual implementation.

2019-08-01drm/msm: add support for per-CRTC max_vblank_count on mdp5Brian Masney
The mdp5 drm/kms driver currently does not work on command-mode DSI panels due to 'vblank wait timed out' errors. This causes a latency of seconds, or tens of seconds in some cases, before content is shown on the panel. This hardware does not have the something that we can use as a frame counter available when running in command mode, so we need to fall back to using timestamps by setting the max_vblank_count to zero. This can be done on a per-CRTC basis, so the convert mdp5 to use drm_crtc_set_max_vblank_count(). This change was tested on a LG Nexus 5 (hammerhead) phone.

The interconnect API uses a consumer/provider-based model, where the providers are the interconnect buses and the consumers could be various drivers. MDSS is one of the interconnect consumers which uses the interconnect APIs to get the path between endpoints and set its bandwidth requirement for the given interconnected path.

2019-05-20drm/fourcc: Pass the format_info pointer to drm_format_plane_cppMaxime Ripard
So far, the drm_format_plane_cpp function was operating on the format's fourcc and was doing a lookup to retrieve the drm_format_info structure and return the cpp. However, this is inefficient since in most cases, we will have the drm_format_info pointer already available so we shouldn't have to perform a new lookup. Some drm_fourcc functions also already operate on the drm_format_info pointer for that reason, so the API is quite inconsistent there. Let's follow the latter pattern and remove the extra lookup while being a bit more consistent. In order to be extra consistent, also rename that function to drm_format_info_plane_cpp and to a static function in the header to match the current policy.

2019-05-20drm: Remove users of drm_format_(horz|vert)_chroma_subsamplingMaxime Ripard
drm_format_horz_chroma_subsampling and drm_format_vert_chroma_subsampling are basically a lookup in the drm_format_info table plus an access to the hsub and vsub fields of the appropriate entry. Most drivers are using this function while having access to the entry already, which means that we will perform an unnecessary lookup. Removing the call to these functions is therefore more efficient. Some drivers will not have access to that entry in the function, but in this case the overhead is minimal (we just have to call drm_format_info() to perform the lookup) and we can even avoid multiple, inefficient lookups in some places that need multiple fields from the drm_format_info structure. This is amplified by the fact that most of the time the callers will have to retrieve both the vsub and hsub fields, meaning that they would perform twice the lookup.

The msm_gem_object structure contains resv and _resv fields that are no longer needed since the reservation object is now stored on drm_gem_object. msm_atomic_prepare_fb() and msm_atomic_prepare_fb() both referenced the wrong reservation object, and would lead to an attempt to dereference a NULL pointer.
