AMDKFD In Linux 4.18 Bringing Vega GPU Support

Written by Michael Larabel in Radeon on 14 May 2018 at 06:12 AM EDT. 8 Comments
The AMDKFD kernel driver in the upcoming Linux 4.17 has the long-awaited discrete Radeon GPU support working so it can be used with the ROCm/OpenCL compute user-space, but Vega GPU support wasn't ready for this release. Fortunately, it's ready for Linux 4.18.

AMDKFD upstream maintainer Oded Gabbay has sent out the AMDKFD-Next pull request for Linux 4.18. Most notable is the presence now of Vega/GFX9 discrete GPU support being ready for this next kernel cycle.

Additionally, the AMD "Kernel Fusion Driver" now also supports Userptr memory mapping. There are also a number of fixes for lock handling, optimized signal handling, a command processor hang fix for APUs, and other fixes.

The current list of queued material for the AMDKFD kernel driver in Linux 4.18 can be found via this pull request.
