In this case, the loader will open the first and last listings, but not the middle. This is because the value of 1 for vendorb_vk.json disables the driver. +Additionaly the loader will scan through registry keys specific to Display +Adapters and all SoftwareComponents assocatied with these adapters for the +locations of JSON manifest files. These keys are reflecting HKR device hive +created during driver installation and contain configuration for base settings, +including OpenGL/D3D ICD location. + +The Device Adapter and SoftwareComponent key paths should be obtained via PnP +Configuration Manager API. In each of this path, a "VulkanDriverName" (and +"VulkanDriverNameWow" for 32-bit Windows on Windows compatibility) key can be +present, what should look like: +``` + HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{Adapter GUID}\000X\VulkanDriverName + HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{Adapter GUID}\000X\VulkanDriverNameWow + + HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{SoftwareComponent GUID}\000X\VulkanDriverName + HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{SoftwareComponent GUID}\000X\VulkanDriverNameWow +``` +If any of these keys exsist and is of type REG_SZ, the loader will open the JSON +manifest file specified by the key valye. Each value must be a full absolute +path to a JSON manifest file. + The Vulkan loader will open each enabled manifest file found to obtain the name or pathname of an ICD shared library (".DLL") file. |
