2021-09-28drm/msm: allow compile_test on !ARMChristian König2-3/+3
MSM is one of the few drivers which won't even compile test on !ARM platforms. Looking into this a bit more it turned out that there is actually not that much missing to at least let the driver compile on x86 as well. So this patch replaces the use of phys_to_page() with the open coded version and provides a dummy for of_drm_find_bridge().

2021-08-30drm/msm: Don't break exclusive fence orderingDaniel Vetter1-1/+2
There's only one exclusive slot, and we must not break the ordering. Adding a new exclusive fence drops all previous fences from the dma_resv. To avoid violating the signalling order we err on the side of over-synchronizing by waiting for the existing fences, even if userspace asked us to ignore them. A better fix would be to us a dma_fence_chain or _array like e.g. amdgpu now uses, but - msm has a synchronous dma_fence_wait for anything from another context, so doesn't seem to care much, - and it probably makes sense to lift this into dma-resv.c code as a proper concept, so that drivers don't have to hack up their own solution each on their own. v2: Improve commit message per Lucas' suggestion.

2021-08-30drm/msm: Improve drm/sched point of no return rulesDaniel Vetter1-7/+6
Originally drm_sched_job_init was the point of no return, after which drivers really should submit a job. I've split that up, which allows us to fix this issue pretty easily. Only thing we have to take care of is to not skip to error paths after that. Other drivers do this the same for out-fence and similar things. v2: It's not really a bugfix, just an improvement, since all drm_sched_job_arm does is reserve the fence number. And gaps should be fine, as long as the drm_sched_job doesn't escape anywhere at all. For robustness it's still better to align with other drivers here and not bail out after job_arm(). v3: I misplaced drm_sched_job_arm by _one_ line! Thanks to Rob for testing and debug help.

2021-08-30drm/sched: Split drm_sched_job_initDaniel Vetter1-0/+2
This is a very confusingly named function, because not just does it init an object, it arms it and provides a point of no return for pushing a job into the scheduler. It would be nice if that's a bit clearer in the interface. But the real reason is that I want to push the dependency tracking helpers into the scheduler code, and that means drm_sched_job_init must be called a lot earlier, without arming the job. v2: - don't change .gitignore (Steven) - don't forget v3d (Emma) v3: Emma noticed that I leak the memory allocated in drm_sched_job_init if we bail out before the point of no return in subsequent driver patches. To be able to fix this change drm_sched_job_cleanup() so it can handle being called both before and after drm_sched_job_arm(). Also improve the kerneldoc for this. v4: - Fix the drm_sched_job_cleanup logic, I inverted the booleans, as usual (Melissa) - Christian pointed out that drm_sched_entity_select_rq() also needs to be moved into drm_sched_job_arm, which made me realize that the job->id definitely needs to be moved too. Shuffle things to fit between job_init and job_arm. v5: Reshuffle the split between init/arm once more, amdgpu abuses drm_sched.ready to signal gpu reset failures. Also document this somewhat. (Christian) v6: Rebase on top of the msm drm/sched support. Note that the drm_sched_job_init() call is completely misplaced, and hence also the split-out drm_sched_entity_push_job(). I've put in a FIXME which the next patch will address. v7: Drop the FIXME in msm, after discussions with Rob I agree it shouldn't be a problem where it is now.

2021-08-10drm/msm/dp: reset aux controller after dp_aux_cmd_fifo_tx() failed.Kuogee Hsieh1-0/+3
Aux hardware calibration sequence requires resetting the aux controller in order for the new setting to take effect. However resetting the AUX controller will also clear HPD interrupt status which may accidentally cause pending unplug interrupt to get lost. Therefore reset aux controller only when link is in connection state when dp_aux_cmd_fifo_tx() fail. This fixes Link Layer CTS cases 4.2.1.1 and 4.2.1.2.

2021-08-10drm/msm/dsi: Fix some reference counted resource leaksChristophe JAILLET1-3/+3
'of_find_device_by_node()' takes a reference that must be released when not needed anymore. This is expected to be done in 'dsi_destroy()'. However, there are 2 issues in 'dsi_get_phy()'. First, if 'of_find_device_by_node()' succeeds but 'platform_get_drvdata()' returns NULL, 'msm_dsi->phy_dev' will still be NULL, and the reference won't be released in 'dsi_destroy()'. Secondly, as 'of_find_device_by_node()' already takes a reference, there is no need for an additional 'get_device()'. Move the assignment to 'msm_dsi->phy_dev' a few lines above and remove the unneeded 'get_device()' to solve both issues.

During board bringups its useful to have a DSI test pattern generator to isolate a DPU vs a DSI issue and focus on the relevant hardware block. To facilitate this, add an API which triggers the DSI controller test pattern. The expected output is a rectangular checkered pattern. This has been validated on a single DSI video mode panel by calling it right after drm_panel_enable() which is also the ideal location to use this as the DSI host and the panel have been initialized by then. Further validation on dual DSI and command mode panel is pending. If there are any fix ups needed for those, it shall be applied on top of this change.
