1264 * different center offset but we re-use the same anv_bo struct when
1265 * we do so. If this happens in the middle of setting up an execbuf,
1266 * we could end up with our list of BOs out of sync with our list of
1269 * 2) The algorithm we use for building the list of unique buffers isn't
1270 * thread-safe. While the client is supposed to syncronize around
1271 * QueueSubmit, this would be extremely difficult to debug if it ever
1272 * came up in the wild due to a broken app. It's better to play it
1273 * safe and just lock around QueueSubmit.
1275 * 3) The anv_cmd_buffer_execbuf function may perform relocations in
1276 * userspace. Due to the fact that the surface state buffer is shared
1277 * between batches, we can't afford to have that happen from multiple
1278 * threads at the same time. Even though the user is supposed to
1279 * ensure this doesn't happen, we play it safe as in (2) above.
1281 * Since the only other things that ever take the device lock such as block
1282 * pool resize only rarely happen, this will almost never be contended so
1283 * taking a lock isn't really an expensive operation in this case.

2153 * - Loader interface v0 is incompatible with later versions. We don't
2156 * - In loader interface v1:
2157 * - The first ICD entrypoint called by the loader is
2158 * vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2160 * - The ICD must statically expose no other Vulkan symbol unless it is
2161 * linked with -Bsymbolic.
2162 * - Each dispatchable Vulkan handle created by the ICD must be
2163 * a pointer to a struct whose first member is VK_LOADER_DATA. The
2164 * ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
2165 * - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2166 * vkDestroySurfaceKHR(). The ICD must be capable of working with
2167 * such loader-managed surfaces.
2169 * - Loader interface v2 differs from v1 in:
2170 * - The first ICD entrypoint called by the loader is
2171 * vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2172 * statically expose this entrypoint.
2174 * - Loader interface v3 differs from v2 in:
2175 * - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2176 * vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2177 * because the loader no longer does so.
