--
-- == Description
--
-- This extension adds a new query to obtain PCI bus information about a
-- physical device.
--
-- Not all physical devices have PCI bus information, either due to the
-- device not being connected to the system through a PCI interface or due
-- to platform specific restrictions and policies. Thus this extension is
-- only expected to be supported by physical devices which can provide the
-- information.
--
-- As a consequence, applications should always check for the presence of
-- the extension string for each individual physical device for which they
-- intend to issue the new query for and should not have any assumptions
-- about the availability of the extension on any given platform.
--
-- == New Structures
--
-- -   Extending
--     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceProperties2':
--
--     -   'PhysicalDevicePCIBusInfoPropertiesEXT'
--
-- == New Enum Constants
--
-- -   'EXT_PCI_BUS_INFO_EXTENSION_NAME'
--
-- -   'EXT_PCI_BUS_INFO_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_PHYSICAL_DEVICE_PCI_BUS_INFO_PROPERTIES_EXT'
--
-- == Version History
--
-- -   Revision 2, 2018-12-10 (Daniel Rakos)
--
--     -   Changed all members of the new structure to have the uint32_t
--         type
--
-- -   Revision 1, 2018-10-11 (Daniel Rakos)
--
--     -   Initial revision
