This series implements cached maps and explicit flushing for both panfrost and panthor. To avoid code/bug duplication, the tricky guts of the cache flusing ioctl which walk the sg list are broken into a new common shmem helper which can be used by any driver.
The PanVK MR to use this lives here: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/36385 Faith Ekstrand (6): drm/shmem: Add a drm_gem_shmem_sync_mmap() helper drm/panthor: Add a PANTHOR_BO_SYNC ioctl drm/panthor: Bump the driver version to 1.6 drm/panfrost: Add flag to map GEM object Write-Back Cacheable drm/panfrost: Add a PANFROST_SYNC_BO ioctl drm/panfrost: Bump the driver version to 1.5 Loïc Molinari (1): drm/panthor: Add flag to map GEM object Write-Back Cacheable drivers/gpu/drm/drm_gem_shmem_helper.c | 64 +++++++++++++++++++++++ drivers/gpu/drm/panfrost/panfrost_drv.c | 67 +++++++++++++++++++++++-- drivers/gpu/drm/panfrost/panfrost_gem.c | 23 +++++++++ drivers/gpu/drm/panfrost/panfrost_gem.h | 2 + drivers/gpu/drm/panthor/panthor_drv.c | 58 +++++++++++++++++++-- drivers/gpu/drm/panthor/panthor_gem.c | 23 +++++++++ drivers/gpu/drm/panthor/panthor_gem.h | 3 ++ include/drm/drm_gem_shmem_helper.h | 3 ++ include/uapi/drm/panfrost_drm.h | 46 +++++++++++++++++ include/uapi/drm/panthor_drm.h | 65 ++++++++++++++++++++++++ 10 files changed, 348 insertions(+), 6 deletions(-) -- 2.50.1
