| * thread-safe. While the client is supposed to syncronize around |
| * 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. |
| * |
| * Since the only other things that ever take the device lock such as block |
| * pool resize only rarely happen, this will almost never be contended so |

| * <https://github.com/KhronosGroup/Vulkan-LoaderAndValidationLayers/blob/master/loader/LoaderAndLayerInterface.md>. |
| * What follows is a condensed summary, to help you navigate the large and |
| * 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. |
