Scheduler to queue jobs and support asynchronous processing with DRM syncobjsīy default DRM_IOCTL_NOUVEAU_VM_BIND does synchronous processing,ĭRM_IOCTL_NOUVEAU_EXEC supports asynchronous processing only. To the GPUs VA space via the new DRM_IOCTL_NOUVEAU_VM_BIND ioctl.ģ) Execute push buffers with the new DRM_IOCTL_NOUVEAU_EXEC ioctl.īoth, DRM_IOCTL_NOUVEAU_VM_BIND and DRM_IOCTL_NOUVEAU_EXEC, make use of the DRM The new VM_BIND Nouveau UAPI build on top of the DRM GPUVA manager, itselfġ) Initialize a GPU VA space via the new DRM_IOCTL_NOUVEAU_VM_INIT ioctlįor UMDs to specify the portion of VA space managed by the kernel andĢ) Allocate and free a VA space region as well as bind and unbind memory for intersecting mapping requests or partial Mappings, making use of the drm_mm range allocator.Ģ) Generically connect GPU VA mappings to their backing buffers, inģ) Provide a common implementation to perform more complex mapping Serves the following purposes in this context.ġ) Provide a dedicated range allocator to track GPU VA allocations and GPU VA spaces in reference to the Vulkan API. The DRM GPUVA manager is indented to help drivers implement userspace-manageable Keep track of GPU virtual address (VA) mappings in a more generic way. Support Vulkan features, such as sparse bindings and sparse residency.įurthermore, with the DRM GPUVA manager it provides a new DRM core feature to This patch series provides a new UAPI for the Nouveau driver in order to
