One of the major changes in this patch series is a much better interface around vmaps, which we achieve by introducing a new set of rust bindings for iosys_map. This patch applies to drm-rust-next with two additional commits from drm-misc-next: e3f4bdaf2c5b ("drm/gem/shmem: Extract drm_gem_shmem_init() from drm_gem_shmem_create()") c08c931060c7 ("drm/gem/shmem: Extract drm_gem_shmem_release() from drm_gem_shmem_free()") The previous version of this patch series can be found here: https://patchwork.freedesktop.org/series/156093/ Asahi Lina (2): rust: helpers: Add bindings/wrappers for dma_resv_lock rust: drm: gem: shmem: Add DRM shmem helper abstraction Lyude Paul (6): rust/drm: Add gem::impl_aref_for_gem_obj! rust: drm: gem: Add raw_dma_resv() function rust: gem: Introduce DriverObject::Args rust: drm: gem: Introduce shmem::SGTable rust: Introduce iosys_map bindings rust: drm/gem: Add vmap functions to shmem bindings drivers/gpu/drm/nova/gem.rs | 5 +- rust/bindings/bindings_helper.h | 3 + rust/helpers/dma-resv.c | 13 + rust/helpers/drm.c | 48 ++- rust/helpers/helpers.c | 2 + rust/helpers/iosys_map.c | 15 + rust/kernel/drm/gem/mod.rs | 80 +++- rust/kernel/drm/gem/shmem.rs | 433 ++++++++++++++++++++ rust/kernel/iosys_map.rs | 705 ++++++++++++++++++++++++++++++++ rust/kernel/lib.rs | 1 + 10 files changed, 1284 insertions(+), 21 deletions(-) create mode 100644 rust/helpers/dma-resv.c create mode 100644 rust/helpers/iosys_map.c create mode 100644 rust/kernel/drm/gem/shmem.rs create mode 100644 rust/kernel/iosys_map.rs base-commit: 5ae65bdcb867555540169ef57876658262a67d87 prerequisite-patch-id: ed9c46db079eee47b437d10234dac813197bc33e prerequisite-patch-id: a2c6c70700e6a333d0b4daf97978fd2e07e24156 -- 2.51.0
