1155 * 1) When a block pool is resized, we create a new gem handle with a
1156 * different size and, in the case of surface states, possibly a
1157 * different center offset but we re-use the same anv_bo struct when
1158 * we do so. If this happens in the middle of setting up an execbuf,
1159 * we could end up with our list of BOs out of sync with our list of
1160 * gem handles.
1161 *
1162 * 2) The algorithm we use for building the list of unique buffers isn't
1163 * thread-safe. While the client is supposed to syncronize around
1164 * QueueSubmit, this would be extremely difficult to debug if it ever
1165 * came up in the wild due to a broken app. It's better to play it
1166 * safe and just lock around QueueSubmit.
1167 *
1168 * 3) The anv_cmd_buffer_execbuf function may perform relocations in
1169 * userspace. Due to the fact that the surface state buffer is shared
1170 * between batches, we can't afford to have that happen from multiple
1171 * threads at the same time. Even though the user is supposed to
1172 * ensure this doesn't happen, we play it safe as in (2) above.
1173 *
1174 * Since the only other things that ever take the device lock such as block
1175 * pool resize only rarely happen, this will almost never be contended so
1176 * taking a lock isn't really an expensive operation in this case.
