From 8446db62f19416963e0b35f45c47684b61612eed Mon Sep 17 00:00:00 2001 From: Lenny Komow Date: Thu, 30 Jul 2020 18:05:12 -0600 Subject: [PATCH] Add a loader features interface This is needed to tell a layer if the loader is sorting physical devices, but it should be generalized so that other loader features could be marked in the future. --- include/vulkan/vk_layer.h | 16 ++++++++++++---- 1 file changed, 12 insertions(+), 4 deletions(-) diff --git a/include/vulkan/vk_layer.h b/include/vulkan/vk_layer.h index fa76520..0651870 100644 --- a/include/vulkan/vk_layer.h +++ b/include/vulkan/vk_layer.h @@ -83,7 +83,8 @@ typedef VkResult(VKAPI_PTR *PFN_PhysDevExt)(VkPhysicalDevice phys_device); typedef enum VkLayerFunction_ { VK_LAYER_LINK_INFO = 0, VK_LOADER_DATA_CALLBACK = 1, - VK_LOADER_LAYER_CREATE_DEVICE_CALLBACK = 2 + VK_LOADER_LAYER_CREATE_DEVICE_CALLBACK = 2, + VK_LOADER_FEATURES = 3, } VkLayerFunction; typedef struct VkLayerInstanceLink_ { @@ -111,6 +112,12 @@ typedef VkResult (VKAPI_PTR *PFN_vkSetDeviceLoaderData)(VkDevice device, typedef VkResult (VKAPI_PTR *PFN_vkLayerCreateDevice)(VkInstance instance, VkPhysicalDevice physicalDevice, const VkDeviceCreateInfo *pCreateInfo, const VkAllocationCallbacks *pAllocator, VkDevice *pDevice, PFN_vkGetInstanceProcAddr layerGIPA, PFN_vkGetDeviceProcAddr *nextGDPA); typedef void (VKAPI_PTR *PFN_vkLayerDestroyDevice)(VkDevice physicalDevice, const VkAllocationCallbacks *pAllocator, PFN_vkDestroyDevice destroyFunction); + +typedef enum VkLoaderFeastureFlagBits { + VK_LOADER_FEATURE_PHYSICAL_DEVICE_SORTING = 0x00000001, +} VkLoaderFlagBits; +typedef VkFlags VkLoaderFeatureFlags; + typedef struct { VkStructureType sType; // VK_STRUCTURE_TYPE_LOADER_INSTANCE_CREATE_INFO const void *pNext; @@ -119,9 +126,10 @@ typedef struct { VkLayerInstanceLink *pLayerInfo; PFN_vkSetInstanceLoaderData pfnSetInstanceLoaderData; struct { - PFN_vkLayerCreateDevice pfnLayerCreateDevice; - PFN_vkLayerDestroyDevice pfnLayerDestroyDevice; - } layerDevice; + PFN_vkLayerCreateDevice pfnLayerCreateDevice; + PFN_vkLayerDestroyDevice pfnLayerDestroyDevice; + } layerDevice; + VkLoaderFeatureFlags loaderFeatures; } u; } VkLayerInstanceCreateInfo; -- 2.7.4
