Bump the minor version to declare event age tracking feature is now available. In kernel amdgpu driver, kfd_wait_on_events is used to support user space signal event wait function. For multiple threads waiting on same event scenery, race condition could occur since some threads after checking signal condition, before calling kfd_wait_on_events, the event interrupt could be fired and wake up other thread which are sleeping on this event. Then those threads could fall into sleep without waking up again. Adding event age tracking in both kernel and user mode, will help avoiding this race condition.

2022-02-07drm/amdkfd: CRIU Introduce Checkpoint-Restore APIsRajneesh Bhardwaj1-1/+80
Checkpoint-Restore in userspace (CRIU) is a powerful tool that can snapshot a running process and later restore it on same or a remote machine but expects the processes that have a device file (e.g. GPU) associated with them, provide necessary driver support to assist CRIU and its extensible plugin interface. Thus, In order to support the Checkpoint-Restore of any ROCm process, the AMD Radeon Open Compute Kernel driver, needs to provide a set of new APIs that provide necessary VRAM metadata and its contents to a userspace component (CRIU plugin) that can store it in form of image files. This introduces some new ioctls which will be used to checkpoint-Restore any KFD bound user process. KFD only allows ioctl calls from the same process that opened the KFD file descriptor. Since these ioctls are expected to be called from a KFD criu plugin which has elevated ptrace attached privileges and CAP_CHECKPOINT_RESTORE capabilities attached with the file descriptors so modify KFD to allow such calls.
