Detailed Description
struct drm_gem_shmem_object - GEM object backed by shmem
Member Data Documentation
◆ base
| struct drm_gem_object drm_gem_shmem_object::base |
@base: Base GEM object
◆ madv
| int drm_gem_shmem_object::madv |
@madv: State for madvise
0 is active/inuse. A negative value is the object is purged. Positive values are driver specific and not used by the helpers.
◆ madv_list
| struct list_head drm_gem_shmem_object::madv_list |
@madv_list: List entry for madvise tracking
Typically used by drivers to track purgeable objects
◆ map_wc
| bool drm_gem_shmem_object::map_wc |
@map_wc: map object write-combined (instead of using shmem defaults).
◆ pages
| struct page** drm_gem_shmem_object::pages |
@pages: Page table
◆ pages_mark_accessed_on_put
| bool drm_gem_shmem_object::pages_mark_accessed_on_put |
@pages_mark_accessed_on_put:
Mark pages as accessed when they are put.
◆ pages_mark_dirty_on_put
| bool drm_gem_shmem_object::pages_mark_dirty_on_put |
@pages_mark_dirty_on_put:
Mark pages as dirty when they are put.
◆ pages_pin_count
| refcount_t drm_gem_shmem_object::pages_pin_count |
@pages_pin_count:
Reference count on the pinned pages table.
Pages are hard-pinned and reside in memory if count greater than zero. Otherwise, when count is zero, the pages are allowed to be evicted and purged by memory shrinker.
◆ pages_use_count
| refcount_t drm_gem_shmem_object::pages_use_count |
@pages_use_count:
Reference count on the pages table. The pages are put when the count reaches zero.
◆ sgt
| struct sg_table* drm_gem_shmem_object::sgt |
@sgt: Scatter/gather table for imported PRIME buffers
◆ vaddr
| void* drm_gem_shmem_object::vaddr |
@vaddr: Kernel virtual address of the backing memory
◆ vmap_use_count
| refcount_t drm_gem_shmem_object::vmap_use_count |
@vmap_use_count:
Reference count on the virtual address. The address are un-mapped when the count reaches zero.
