34 .Nd generic framebuffer console driver
38 .Cd "wsdisplay* at genfb?"
42 driver provides support for generic framebuffers that have no native driver.
43 All it needs are some parameters to describe the framebuffer and an address.
47 bus the driver is configured via device properties:
49 .It Dv width Pq Li uint32
51 .It Dv height Pq Li uint32
53 .It Dv stride Pq Li uint32
55 .It Dv depth Pq Li uint32
57 .It Dv is_console Pq Li bool
60 will try to become the system console.
61 .It Dv address Pq Li uint32
62 Bus address of the framebuffer.
67 all those parameters are retrieved from the firmware.
74 There is no way to change the color map even when the firmware supports it.
77 bus frontend has only been tested on macppc, i386, and amd64 and requires
78 machine dependent code to pass the properties mentioned above.
79 So far only macppc, i386, and amd64 provides them.
