+ * a SW object combining a user-mode provided "syncvar" and a scheduler event
+ * that can be signaled through a defined GPU interrupt. A syncvar is
+ * a process virtual memory location of 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 surfaced
