drm/i915/vm_bind: Add VM_BIND functionality
|
expand
|
DRM_I915_GEM_VM_BIND/UNBIND ioctls allows UMD to bind/unbind GEM buffer objects (BOs) or sections of a BOs at specified GPU virtual addresses on a specified address space (VM). Multiple mappings can map to the same physical pages of an object (aliasing). These mappings (also referred to as persistent mappings) will be persistent across multiple GPU submissions (execbuf calls) issued by the UMD, without user having to provide a list of all required mappings during each submission (as required by older execbuf mode). This patch series support VM_BIND version 1, as described by the param I915_PARAM_VM_BIND_VERSION. Add new execbuf3 ioctl (I915_GEM_EXECBUFFER3) which only works in vm_bind mode. The vm_bind mode only works with this new execbuf3 ioctl. The new execbuf3 ioctl will not have any execlist support and all the legacy support like relocations etc., are removed. TODOs: * Support out fence for VM_UNBIND ioctl. * Async VM_UNBIND support. * Optimizations. NOTEs: * It is based on below VM_BIND design+uapi rfc. Documentation/gpu/rfc/i915_vm_bind.rst * The IGT RFC series is posted as, [PATCH i-g-t 0/8] vm_bind: Add VM_BIND validation support Signed-off-by: Niranjana Vishwanathapura <niranjana.vishwanathapura@intel.com> Niranjana Vishwanathapura (16): drm/i915/vm_bind: Expose vm lookup function drm/i915/vm_bind: Add __i915_sw_fence_await_reservation() drm/i915/vm_bind: Expose i915_gem_object_max_page_size() drm/i915/vm_bind: Add support to create persistent vma drm/i915/vm_bind: Implement bind and unbind of object drm/i915/vm_bind: Support for VM private BOs drm/i915/vm_bind: Add support to handle object evictions drm/i915/vm_bind: Support persistent vma activeness tracking drm/i915/vm_bind: Add out fence support drm/i915/vm_bind: Abstract out common execbuf functions drm/i915/vm_bind: Use common execbuf functions in execbuf path drm/i915/vm_bind: Implement I915_GEM_EXECBUFFER3 ioctl drm/i915/vm_bind: Update i915_vma_verify_bind_complete() drm/i915/vm_bind: Handle persistent vmas in execbuf3 drm/i915/vm_bind: userptr dma-resv changes drm/i915/vm_bind: Add uapi for user to enable vm_bind_mode drivers/gpu/drm/i915/Makefile | 3 + drivers/gpu/drm/i915/gem/i915_gem_context.c | 20 +- drivers/gpu/drm/i915/gem/i915_gem_context.h | 3 + drivers/gpu/drm/i915/gem/i915_gem_create.c | 60 +- drivers/gpu/drm/i915/gem/i915_gem_dmabuf.c | 6 + .../gpu/drm/i915/gem/i915_gem_execbuffer.c | 521 +---------- .../gpu/drm/i915/gem/i915_gem_execbuffer3.c | 856 ++++++++++++++++++ .../drm/i915/gem/i915_gem_execbuffer_common.c | 664 ++++++++++++++ .../drm/i915/gem/i915_gem_execbuffer_common.h | 74 ++ drivers/gpu/drm/i915/gem/i915_gem_ioctls.h | 2 + drivers/gpu/drm/i915/gem/i915_gem_object.c | 3 + drivers/gpu/drm/i915/gem/i915_gem_object.h | 2 + .../gpu/drm/i915/gem/i915_gem_object_types.h | 3 + drivers/gpu/drm/i915/gem/i915_gem_ttm.c | 3 + drivers/gpu/drm/i915/gem/i915_gem_userptr.c | 17 + drivers/gpu/drm/i915/gem/i915_gem_vm_bind.h | 30 + .../drm/i915/gem/i915_gem_vm_bind_object.c | 418 +++++++++ drivers/gpu/drm/i915/gt/intel_gtt.c | 18 + drivers/gpu/drm/i915/gt/intel_gtt.h | 27 + drivers/gpu/drm/i915/i915_driver.c | 4 + drivers/gpu/drm/i915/i915_drv.h | 2 + drivers/gpu/drm/i915/i915_gem_gtt.c | 39 + drivers/gpu/drm/i915/i915_gem_gtt.h | 3 + drivers/gpu/drm/i915/i915_getparam.c | 3 + drivers/gpu/drm/i915/i915_sw_fence.c | 28 +- drivers/gpu/drm/i915/i915_sw_fence.h | 23 +- drivers/gpu/drm/i915/i915_vma.c | 111 ++- drivers/gpu/drm/i915/i915_vma.h | 52 +- drivers/gpu/drm/i915/i915_vma_types.h | 42 + include/uapi/drm/i915_drm.h | 282 +++++- 30 files changed, 2799 insertions(+), 520 deletions(-) create mode 100644 drivers/gpu/drm/i915/gem/i915_gem_execbuffer3.c create mode 100644 drivers/gpu/drm/i915/gem/i915_gem_execbuffer_common.c create mode 100644 drivers/gpu/drm/i915/gem/i915_gem_execbuffer_common.h create mode 100644 drivers/gpu/drm/i915/gem/i915_gem_vm_bind.h create mode 100644 drivers/gpu/drm/i915/gem/i915_gem_vm_bind_object.c
