// a certain size that can be accessed by CPU and GPU shader code within the process to set
// and query the content within that memory. The definition of the content is determined by
// the HSA runtime and potentially GPU shader code interfacing with the HSA runtime.
// The syncvar values may be commonly written through an PM4 WRITE_DATA packet in the
// user mode instruction stream.
// The OS scheduler event is typically associated and signaled by an interrupt issued by
// the GPU, but other HSA system interrupt conditions from other HW (e.g. IOMMUv2) may be
