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.

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. Acked-by:

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.

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. Signed-off-by:

After "5918045c 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. Signed-off-by:
