Defines plane ordering by hard-coding an immutable Z position from the first plane, used as primary layer, to the next ones as overlay in order of instantiation. This zpos is only an information as it is not possible to modify it, blending operations are still applied from the top to the bottom layer.

drm_sched_job_cleanup() will pass an uninitialized fence to drm_sched_fence_free(), which will cause to_drm_sched_fence() to return a NULL fence object, causing a NULL pointer deref when this NULL object is passed to kmem_cache_free(). Let's create a new drm_sched_fence_free() function that takes a drm_sched_fence pointer and suffix the old function with _rcu. While at it, complain if drm_sched_fence_free() is passed an initialized fence or if drm_sched_fence_free_rcu() is passed an uninitialized fence.

While that didn't change anything for quite sometime, it actually become important after CSC code rework with commit ea067aee ("drm/sun4i: de2/de3: Remove redundant CSC matrices"). Without this fix, colours are completely off for supported YVU formats on SoCs with DE2 (A64, H3, R40, etc.). Fix the issue by enclosing macro arguments in parenthesis.

These two arrays are populated with data read from the I2C device through regmap_read(), and the data is then compared with hardcoded vendor/product ID values of supported chips. However, the return value of regmap_read() was never checked. This is fine, as long as the two arrays are zero-initialized, so that we don't compare the vendor/product IDs against whatever garbage is left on the stack. Address this issue by zero-initializing these two arrays. Signed-off-by:

Specifically document the new/clarified rules around how the shared fences do not have any ordering requirements against the exclusive fence. But also document all the things a bit better, given how central struct dma_resv to dynamic buffer management the docs have been very inadequat. - Lots more links to other pieces of the puzzle. Unfortunately ttm_buffer_object has no docs, so no links :-( - Explain/complain a bit about dma_resv_locking_ctx(). I still don't like that one, but fixing the ttm call chains is going to be horrible. Plus we want to plug in real slowpath locking when we do that anyway. - Main part of the patch is some actual docs for struct dma_resv. Overall I think we still have a lot of bad naming in this area (e.g. dma_resv.fence is singular, but contains the multiple shared fences), but I think that's more indicative of how the semantics and rules are just not great. Another thing that's real awkard is how chaining exclusive fences right now means direct dma_resv.exclusive_fence pointer access with an rcu_assign_pointer. Not so great either. v2: - Fix a pile of typos (Matt, Jason) - Hammer it in that breaking the rules leads to use-after-free issues around dma-buf sharing (Christian) Reviewed-by:

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.
