+Scanning Halted Waves
+---------------------
+
+If the waves have been halted (say with the function umr_sq_cmd_halt_waves())
then
+a list of halted valid waves can be made with the following function:
+
+
+::
+
+ struct umr_wave_data *umr_scan_wave_data(struct umr_asic *asic)
+
+This will return NULL on error (or no halted waves) or a pointer
+to the following structure:
+
+::
+
+ struct umr_wave_data {
+ uint32_t vgprs[64 * 256], sgprs[1024];
+ int se, sh, cu, simd, wave, have_vgprs;
+ struct umr_wave_status ws;
+ struct umr_wave_thread *threads;
+ struct umr_wave_data *next;
+ };
+
+The list of waves are stored as a linked list terminated by the
+last node having 'next' point to NULL.
