[PATCH 00/20] Add KFD GPUVM support for dGPUs v4

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Rebased and integrated review feedback from v3:
* Removed vm->vm_context field
* Use uninterruptible waiting in initial PD validation to avoid ERESTARTSYS
* Return number of successful map/unmap operations in failure cases
* Facilitate partial retry after failed map/unmap
* Added comments with parameter descriptions to new APIs
* Defined AMDKFD_IOC_FREE_MEMORY_OF_GPU write-only

This patch series also adds Userptr support in patches 15-20.
