This patch series is a Panfrost port of the already merged patches previously discussed at [1].
The differences are minimal. In this latest revision, the notion of internal BOs, akin to that of Panthor kernel-only BO's has been introduced, so that the perfcnt sample buffer and imported PRIME objects can be given a tag. The under-discussion Mesa MR that would allow one to test these changes can be found at [2]. The way BO flags is printed is also slightly different. Changelog: v3: - Fixed spelling of Panfrost device pointer variable names - Fixed invalid memory access bug when freeing Panfrost GEM objects for PRIME imported buffers - Added function for internally tagging BOs (mainly for the perfcnt sample buffer) - Added new commit for fixing Panfrost Device variable spelling mistakes. v2: - Introduced u64_to_user_ptr() for casting user pointers - Refined documentation for uAPI bo labelling struct fields - Moved panfrost device debugfs struct fields into a single debugfs struct - Add BO to debugfs GEMs list right before creating its handle to avoid unnecessary initialised field.
