1139 * 1) When a block pool is resized, we create a new gem handle with a
1140 * different size and, in the case of surface states, possibly a
1141 * different center offset but we re-use the same anv_bo struct when
1142 * we do so. If this happens in the middle of setting up an execbuf,
1143 * we could end up with our list of BOs out of sync with our list of
1144 * gem handles.
1145 *
1146 * 2) The algorithm we use for building the list of unique buffers isn't
1147 * thread-safe. While the client is supposed to syncronize around
1148 * QueueSubmit, this would be extremely difficult to debug if it ever
1149 * came up in the wild due to a broken app. It's better to play it
1150 * safe and just lock around QueueSubmit.
1151 *
1152 * 3) The anv_cmd_buffer_execbuf function may perform relocations in
1153 * userspace. Due to the fact that the surface state buffer is shared
1154 * between batches, we can't afford to have that happen from multiple
1155 * threads at the same time. Even though the user is supposed to
1156 * ensure this doesn't happen, we play it safe as in (2) above.
1157 *
1158 * Since the only other things that ever take the device lock such as block
1159 * pool resize only rarely happen, this will almost never be contended so
1160 * taking a lock isn't really an expensive operation in this case.
