1112 * different size and, in the case of surface states, possibly a
1113 * different center offset but we re-use the same anv_bo struct when
1114 * we do so. If this happens in the middle of setting up an execbuf,
1115 * we could end up with our list of BOs out of sync with our list of
1116 * gem handles.
1117 *
1118 * 2) The algorithm we use for building the list of unique buffers isn't
1119 * thread-safe. While the client is supposed to syncronize around
1120 * QueueSubmit, this would be extremely difficult to debug if it ever
1121 * came up in the wild due to a broken app. It's better to play it
1122 * safe and just lock around QueueSubmit.
1123 *
1124 * 3) The anv_cmd_buffer_execbuf function may perform relocations in
1125 * userspace. Due to the fact that the surface state buffer is shared
1126 * between batches, we can't afford to have that happen from multiple
1127 * threads at the same time. Even though the user is supposed to
1128 * ensure this doesn't happen, we play it safe as in (2) above.
1129 *
1130 * Since the only other things that ever take the device lock such as block
1131 * pool resize only rarely happen, this will almost never be contended so
1132 * taking a lock isn't really an expensive operation in this case.
