AMDKFD HSA Linux Driver Improvements Land Today

For those not too busy discussing and digging through the new open-source AMDGPU kernel driver that was published yesterday, out today are some new patches for AMDKFD, the HSA Linux kernel driver.

As some material for eventual integration into the Linux 4.2 kernel, Oded Gabbay as the AMDKFD maintainer pushed out nine new patches so far today. The new patch series begins here.

Among the improvements with these new patches are an AMDKFD interrupt handling module, an events module and events IOCTL, memory exception handling, bad opcode exception handling, and after these improvements the AMDKFD kernel driver version was bumped to v0.7.2.

The Carrizo APUs coming out this summer will be the first fully HSA 1.0 compliant hardware when this AMDKFD driver stack should begin to shine along with AMD's open-source user-space HSA library.
