+The `coop_mat` attribute declares an OpenCL cooperative matrix type.
Cooperative
+matrix operations are distributed across a set of invocations, such as a
+subgroup, allowing the implementation to optimize matrix multiply operations.
+
+The attribute is applied to a scalar numerical component type and takes four
+arguments:
+
+```c
+__attribute__((coop_mat(scope, rows, columns, use)))
+```
+- scope specifies the memory scope of the cooperative matrix.
+ It must be one of the supported OpenCL memory scopes, such as
CLK_COOPERATIVE_MATRIX_SCOPE_SUBGROUP.

It is just Subgroup scope, others are not allowed per OpenCL spec.
