The use of the drmP.h header file is deprecated. Remove use from all files in drm/* so people do not look there and follow a bad example. Build tested allyesconfig,allmodconfig on x86, arm etc. Including alpha that is as always more challenging than the rest.

In drm_load_edid_firmware(), fwstr is allocated by kstrdup(). And fwstr is dereferenced in the following codes. However, memory allocation functions such as kstrdup() may fail and returns NULL. Dereferencing this null pointer may cause the kernel go wrong. Thus we should check this kstrdup() operation. Further, if kstrdup() returns NULL, we should return ERR_PTR(-ENOMEM) to the caller site.

2019-05-24drm/mcde: Add new driver for ST-Ericsson MCDELinus Walleij10-0/+3729
This adds a new DRM driver for the ST-Ericsson Multi Channel Display Engine, MCDE display controller. This hardware has three independent DSI hosts and can composit and display several memory buffers onto an LCD display. It was developed for several years inside of ST-Ericsson and shipped with a few million mobile phones from Sony and Samsung, as well as with the Snowball community development board. The driver is currently pretty rudimentary but supports a simple framebuffer so we can get penguins and graphics when using these SoCs.

2019-05-23drm/vc4: Allocate binner bo when starting to use the V3DPaul Kocialkowski6-20/+125
The binner BO is not required until the V3D is in use, so avoid allocating it at probe and do it on the first non-dumb BO allocation. Keep track of which clients are using the V3D and liberate the buffer when there is none left, using a kref. Protect the logic with a mutex to avoid race conditions. The binner BO is created at the time of the first render ioctl and is destroyed when there is no client and no exec job using it left. The Out-Of-Memory (OOM) interrupt also gets some tweaking, to avoid enabling it before having allocated a binner bo. We also want to keep the BO alive during runtime suspend/resume to avoid failing to allocate it at resume. This happens when the CMA pool is full at that point and results in a hard crash.

2019-05-22drm: Replace drm_gem_vram_push_to_system() with kunmap + unpinThomas Zimmermann4-61/+20
The push-to-system function forces a buffer out of video RAM. This decision should rather be made by the memory manager. By replacing the function with calls to the kunmap and unpin functions, the buffer's memory becomes available, but the buffer remains in VRAM until it's evicted by a pin operation. This patch replaces the remaining instances of drm_gem_vram_push_to_system() in ast and mgag200, and removes the function from DRM.

2019-05-22drm/scheduler: Fix job cleanup without timeout handlerErico Nunes1-1/+2
After "5918045c4ed4 drm/scheduler: rework job destruction", jobs are only deleted when the timeout handler is able to be cancelled successfully. In case no timeout handler is running (timeout == MAX_SCHEDULE_TIMEOUT), job cleanup would be skipped which may result in memory leaks. Add the handling for the (timeout == MAX_SCHEDULE_TIMEOUT) case in drm_sched_cleanup_jobs.

2019-05-21drm/lima: add timeout to drm scheduler initErico Nunes2-8/+5
After "5918045c4ed4 drm/scheduler: rework job destruction", lima started to leak memory due to buffers not being destroyed after job execution in the drm scheduler. This started happening because the drm scheduler only destroyed buffers after cancelling the job timeout handler, and for lima this handler was never started as lima specified a MAX_SCHEDULE_TIMEOUT timeout. Lima seems to run well in its current state with a real timeout, so to make it more aligned with the other drivers from now on, let's use a real default timeout. This also fixes the observed memory leaks. The 500ms value was chosen as it is the current value for all other embedded gpu drivers using drm sched.

2019-05-21drm/bochs: Fix connector leak during driver unloadSam Bobroff1-0/+2
When unloading the bochs-drm driver, a warning message is printed by drm_mode_config_cleanup() because a reference is still held to one of the drm_connector structs. Correct this by calling drm_atomic_helper_shutdown() in bochs_pci_remove(). Fixes: 6579c39594ae ("drm/bochs: atomic: switch planes to atomic, wire up helpers.")

drm_get_format_info directly calls into drm_format_info, but takes directly a struct drm_mode_fb_cmd2 pointer, instead of the fourcc directly. It's shorter to not dereference it, and we can customise the behaviour at the driver level if we want to, so let's switch to it where it makes sense.

2019-05-20drm/fourcc: Pass the format_info pointer to drm_format_plane_width/heightMaxime Ripard2-54/+6
So far, the drm_format_plane_height/width functions were 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. The parameters order have also be changed to match the other functions prototype.

2019-05-20drm: Remove users of drm_format_(horz|vert)_chroma_subsamplingMaxime Ripard12-110/+38
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.
