Detailed Description

struct drm_gpuva - structure to track a GPU VA mapping

This structure represents a GPU VA mapping and is associated with a &drm_gpuvm.

Typically, this structure is embedded in bigger driver structures.

Member Data Documentation

__subtree_last

u64 drm_gpuva::__subtree_last

@rb.__subtree_last: needed by the interval tree, holding last-in-subtree

addr

u64 drm_gpuva::addr

@va.addr: the start address

entry

struct list_head drm_gpuva::entry

@gem.entry: the &list_head to attach this object to a &drm_gpuvm_bo

@rb.entry: The &list_head to additionally connect &drm_gpuvas in the same order they appear in the interval tree. This is useful to keep iterating &drm_gpuvas from a start node found through the rb-tree while doing modifications on the rb-tree itself.

flags

enum drm_gpuva_flags drm_gpuva::flags

@flags: the &drm_gpuva_flags for this mapping

[struct]

struct { ... } drm_gpuva::gem

@gem: structure containing the &drm_gem_object and its offset

node

struct rb_node drm_gpuva::node

@rb.node: the rb-tree node

obj

struct drm_gem_object* drm_gpuva::obj

@gem.obj: the mapped &drm_gem_object

offset

u64 drm_gpuva::offset

@gem.offset: the offset within the &drm_gem_object

range

u64 drm_gpuva::range

[struct]

struct { ... } drm_gpuva::rb

@rb: structure containing data to store &drm_gpuvas in a rb-tree

[struct]

struct { ... } drm_gpuva::va

@va: structure containing the address and range of the &drm_gpuva

vm

struct drm_gpuvm* drm_gpuva::vm

@vm: the &drm_gpuvm this object is associated with

vm_bo

struct drm_gpuvm_bo* drm_gpuva::vm_bo

@vm_bo: the &drm_gpuvm_bo abstraction for the mapped &drm_gem_object
