Panfrost has a re-implementation of drm_gem_dumb_map_offset() with an extra bug regarding the handling of imported buffers. However we don't really want Panfrost calling _dumb functions because it's not a KMS driver. This series renames drm_gem_dumb_map_offset() to drop the '_dumb' and introduces a shmem helper to wrap it. This means that the shmem implementation can be kept in sync with the semantics the drm_gem_shmem_mmap() callback provides. v1: https://lore.kernel.org/lkml/20190513143244.16478-1-steven.price@xxxxxxx/ Changes since v1: * Rename drm_gem_dumb_map_offset to drop _dumb * Add a shmem helper Steven Price (3): drm/gem: Rename drm_gem_dumb_map_offset() to drm_gem_map_offset() drm: shmem: Add drm_gem_shmem_map_offset() wrapper drm/panfrost: Use drm_gem_shmem_map_offset() drivers/gpu/drm/drm_dumb_buffers.c | 4 ++-- drivers/gpu/drm/drm_gem.c | 6 +++--- drivers/gpu/drm/drm_gem_shmem_helper.c | 20 ++++++++++++++++++++ drivers/gpu/drm/exynos/exynos_drm_gem.c | 3 +-- drivers/gpu/drm/panfrost/panfrost_drv.c | 16 ++-------------- include/drm/drm_gem.h | 4 ++-- include/drm/drm_gem_shmem_helper.h | 2 ++ 7 files changed, 32 insertions(+), 23 deletions(-) -- 2.20.1 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
