Description

This extension provides new facilities to query DRM properties for physical devices, enabling users to match Vulkan physical devices with DRM nodes on Linux.

Its functionality closely overlaps with EGL_EXT_device_drm1^. Unlike the EGL extension, this extension does not expose a string containing the name of the device file and instead exposes device minor numbers.

DRM defines multiple device node types. Each physical device may have one primary node and one render node associated. Physical devices may have no primary node (e.g. if the device does not have a display subsystem), may have no render node (e.g. if it is a software rendering engine), or may have neither (e.g. if it is a software rendering engine without a display subsystem).

To query DRM properties for a physical device, chain PhysicalDeviceDrmPropertiesEXT to PhysicalDeviceProperties2.

New Structures

VkPhysicalDeviceDrmPropertiesEXT - Structure containing DRM information of a physical device

Description

If the PhysicalDeviceDrmPropertiesEXT structure is included in the pNext chain of the PhysicalDeviceProperties2 structure passed to getPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

These are properties of the DRM information of a physical device.
