* QueueSubmit, this would be extremely difficult to debug if it ever
* came up in the wild due to a broken app. It's better to play it
* safe and just lock around QueueSubmit.
*
* 3) The anv_cmd_buffer_execbuf function may perform relocations in
* userspace. Due to the fact that the surface state buffer is shared
* between batches, we can't afford to have that happen from multiple
* threads at the same time. Even though the user is supposed to
* ensure this doesn't happen, we play it safe as in (2) above.

* confusing official doc.
*
* - Loader interface v0 is incompatible with later versions. We don't
* support it.
*
* - In loader interface v1:
* - The first ICD entrypoint called by the loader is
* vk_icdGetInstanceProcAddr(). The ICD must statically expose this
* entrypoint.
* - The ICD must statically expose no other Vulkan symbol unless it is
* linked with -Bsymbolic.
* - Each dispatchable Vulkan handle created by the ICD must be
* a pointer to a struct whose first member is VK_LOADER_DATA. The
* ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
* - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
* vkDestroySurfaceKHR(). The ICD must be capable of working with
* such loader-managed surfaces.
*
* - Loader interface v2 differs from v1 in:
* - The first ICD entrypoint called by the loader is
* vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
* statically expose this entrypoint.
*
* - Loader interface v3 differs from v2 in:
* - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
* vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
* because the loader no longer does so.
