Detailed Description
ReactOS Framebuffer-specific video device configuration data.
Supplemental data that extends CM_VIDEO_DEVICE_DATA. It is appended to the standard configuration resource list, as a CmResourceTypeDeviceSpecific data descriptor.
- Any optional Irql/Vector interrupt settings are specified with a CmResourceTypeInterrupt descriptor, while any other I/O port is specified with a CmResourceTypePort descriptor.
- The video RAM physical address base and size are specified by the first CmResourceTypeMemory descriptor in the list.
- The framebuffer is the actively displayed part of video RAM, and is specified via the FrameBufferOffset member.
