This patch series is a prototype for supporting CRIU for ROCm applications. More work is needed before this can be upstreamed and released, including a new ioctl API that is extensible without breaking the ABI.
The user mode code to go with this can be found at https://github.com/RadeonOpenCompute/criu/tree/criu-dev/test/others/ext-kfd It will be discussed with the CRIU community on criu@openvz.org and evolve together with this patch series.
This patch series is also available on github: https://github.com/RadeonOpenCompute/ROCK-Kernel-Driver/commits/fxkamd/criu-...
