This series: 1. Adds common drm-shmem memory shrinker 2. Enables shrinker for VirtIO-GPU driver 3. Switches Panfrost driver to the common shrinker Related patches: Mesa: https://gitlab.freedesktop.org/digetx/mesa/-/commits/virgl-madvise igt: https://gitlab.freedesktop.org/digetx/igt-gpu-tools/-/commits/virtio-madvise https://gitlab.freedesktop.org/digetx/igt-gpu-tools/-/commits/panfrost-madvise I'll upstream Mesa and igt patches once kernel part will be merged. Changelog: v8: - Rebased on top of recent linux-next that now has dma-buf locking convention patches merged, which was blocking shmem shrinker before. - Shmem shrinker now uses new drm_gem_lru helper. - Dropped Steven Price t-b from the Panfrost patch because code changed significantly since v6 and should be re-tested. v7: - dma-buf locking convention v6: https://lore.kernel.org/dri-devel/20220526235040.678984-1-dmitry.osipenko@xxxxxxxxxxxxx/ Dmitry Osipenko (7): drm/msm/gem: Prevent blocking within shrinker loop drm/shmem-helper: Don't use vmap_use_count for dma-bufs drm/shmem-helper: Switch to reservation lock drm/shmem-helper: Add memory shrinker drm/gem: Add drm_gem_pin_unlocked() drm/virtio: Support memory shrinking drm/panfrost: Switch to generic memory shrinker drivers/gpu/drm/drm_gem.c | 38 +- drivers/gpu/drm/drm_gem_shmem_helper.c | 648 ++++++++++++++---- drivers/gpu/drm/lima/lima_gem.c | 8 +- drivers/gpu/drm/msm/msm_gem_shrinker.c | 8 +- drivers/gpu/drm/panfrost/Makefile | 1 - drivers/gpu/drm/panfrost/panfrost_device.h | 4 - drivers/gpu/drm/panfrost/panfrost_drv.c | 26 +- drivers/gpu/drm/panfrost/panfrost_gem.c | 33 +- drivers/gpu/drm/panfrost/panfrost_gem.h | 9 - .../gpu/drm/panfrost/panfrost_gem_shrinker.c | 122 ---- drivers/gpu/drm/panfrost/panfrost_job.c | 18 +- drivers/gpu/drm/panfrost/panfrost_mmu.c | 19 +- drivers/gpu/drm/virtio/virtgpu_drv.h | 18 +- drivers/gpu/drm/virtio/virtgpu_gem.c | 55 ++ drivers/gpu/drm/virtio/virtgpu_ioctl.c | 37 + drivers/gpu/drm/virtio/virtgpu_kms.c | 9 + drivers/gpu/drm/virtio/virtgpu_object.c | 138 +++- drivers/gpu/drm/virtio/virtgpu_plane.c | 22 +- drivers/gpu/drm/virtio/virtgpu_vq.c | 40 ++ include/drm/drm_device.h | 4 + include/drm/drm_gem.h | 7 +- include/drm/drm_gem_shmem_helper.h | 99 ++- include/uapi/drm/virtgpu_drm.h | 14 + 23 files changed, 1003 insertions(+), 374 deletions(-) delete mode 100644 drivers/gpu/drm/panfrost/panfrost_gem_shrinker.c -- 2.37.3
