     `amdgpu.sched_barrier` serves as a barrier that could be
     configured to restrict movements of instructions through it as
     defined by sched_barrier_opts.

+    ```mlir
+    // Barrier allowing no dependent instructions
+    amdgpu.sched_barrier allow = <none>
+    // Barrier allowing specific execution units

Similarly, I find the use of execution units here confusing. I think something like "barrier allowing VALU and VMEM instructions to be scheduled across it" to be more straightforward.
