From: Thierry Reding <tred...@nvidia.com> Buffer mappings used in job submissions are usually small and not rapidly reused as opposed to framebuffers (which are usually large and rapidly reused, for example when page-flipping between double-buffered framebuffers). Avoid going through the mapping cache for these buffers since the cache would also lead to leaks if nobody is ever releasing the cache's last reference. For DRM/KMS these last references are dropped when the framebuffers are removed and therefore no longer needed. While at it, also add a note about the need to explicitly remove the final reference to the mapping in the cache. Signed-off-by: Thierry Reding <tred...@nvidia.com>
I have tested this and verified that it is working well. Reviewed-by: Jon Hunter <jonath...@nvidia.com> Tested-by: Jon Hunter <jonath...@nvidia.com> Thanks Jon -- nvpublic
