Phoronix: AMD Posts Linux Patches For Better Graphics/Compute Interoperability & Other Benefits

AMD today posted a set of interesting patches for enabling better integration of their AMDKFD (Kernel Fusion Driver, what is their compute kernel driver) memory management with Linux's DRM GEM ioctl API. In turn the code allows managing virtual address (VA) mappings in compute VMs with the GEM_VA ioctl interface for greater control of buffers imported via DMA-BUF...

Will this be available on consumer GPUs? What about non-compute tasks to Intel hegemony in this will end?

The patches all seem to be in code that is common to consumer, workstation and datacenter cards. My impression is that the intention of the patch set is to help extend DMA-BUF support that we already have for graphics objects (managed by amdgpu/libdrm) to compute objects managed by amdkfd/libhsakmt so if I understand your question correctly the support is already there for non compute tasks.

Great!
