AMD --
Besides Intel DRM updates landing today in DRM-Next for eventual merging into the Linux 4.2 kernel, AMD landed some changes to their HSA kernel driver named AMDKFD.

The AMDKFD pull that was pushed today into DRM-Next for Linux 4.2 includes new interrupts and events modules, a new kernel module parameter for controlling SIGTERM behavior when a memory exception ocurs inside the GPU kernel, improvements to the SDMA code, and other changes. The events support within the new AMDKFD code is part of the open-source HSA runtime stack for knowing when a dispatched job has been completed and is a prerequisite for upstreaming the HSA debugger support in the future.

More details on the latest AMDKFD HSA kernel driver changes for this next kernel cycle can be found via this Git commit to DRM-Next.
