16 r128 is an Xorg driver for ATI Rage 128 based video cards. It contains
17 full support for 8, 15, 16 and 24 bit pixel depths, hardware accelera‐
18 tion of drawing primitives, hardware cursor, video modes up to
19 1800x1440 @ 70Hz, doublescan modes (e.g., 320x200 and 320x240), gamma
20 correction at all pixel depths, a fully programming dot clock and
21 robust text mode restoration for VT switching. Dualhead is supported
22 on M3/M4 mobile chips.

25 The r128 driver supports all ATI Rage 128 based video cards including
26 the Rage Fury AGP 32MB, the XPERT 128 AGP 16MB and the XPERT 99 AGP
27 8MB.

30 Please refer to xorg.conf(5) for general configuration details. This
31 section only covers configuration details specific to this driver.
32 The driver auto-detects all device information necessary to initialize
34 the card. However, if you have problems with auto-detection, you can
35 specify:
36 VideoRam - in kilobytes
38 MemBase - physical address of the linear framebuffer
39 IOBase - physical address of the MMIO registers
40 ChipID - PCI DEVICE ID
41 In addition, the following driver Options are supported:
43 Option "SWcursor" "boolean"
45 Selects software cursor. The default is off.
46 Option "NoAccel" "boolean"
48 Enables or disables all hardware acceleration. The default is
49 to enable hardware acceleration.
50 Option "Dac6Bit" "boolean"
52 Enables or disables the use of 6 bits per color component when
53 in 8 bpp mode (emulates VGA mode). By default, all 8 bits per
54 color component are used. The default is off.
55 Option "VideoKey" "integer"
57 This overrides the default pixel value for the YUV video overlay
58 key. The default value is undefined.
59 Option "Display" "string"
61 Select display mode for devices which support flat panels. Sup‐
62 ported modes are:
63 "FP" - use flat panel;
65 "CRT" - use cathode ray tube;
67 "Mirror" - use both FP and CRT;
69 "BIOS" - use mode as configured in the BIOS.
71 The default is FP.
73 The following Options are mostly important for non-x86 architectures:
76 Option "ProgramFPRegs" "boolean"
78 Enable or disable programming of the flat panel registers.
79 Beware that this may damage your panel, so use this at your own
80 risk. The default depends on the device.
81 Option "PanelWidth" "integer"
83 Option "PanelHeight" "integer"
85 Override the flat panel dimensions in pixels. They are used to
86 program the flat panel registers and normally determined using
87 the video card BIOS. If the wrong dimensions are used, the sys‐
88 tem may hang.
89 Option "UseFBDev" "boolean"
91 Enable or disable use of an OS-specific framebuffer device
92 interface (which is not supported on all OSs). See fbdevhw(4)
93 for further information. Default: on for PowerPC, off for other
94 architectures.
95 Option "DMAForXv" "boolean"
97 Try or don't try to use DMA for Xv image transfers. This will
98 reduce CPU usage when playing big videos like DVDs, but may
99 cause instabilities. Default: off.
100 The following additional Options are supported:
103 Option "ShowCache" "boolean"
105 Enable or disable viewing offscreen cache memory. A development
106 debug option. Default: off.
107 Option "VGAAccess" "boolean"
109 Tell the driver if it can do legacy VGA IOs to the card. This is
110 necessary for properly resuming consoles when in VGA text mode,
111 but shouldn't be if the console is using radeonfb or some other
112 graphic mode driver. Some platforms like PowerPC have issues
113 with those, and they aren't necessary unless you have a real
114 text mode in console. The default is off on PowerPC and SPARC
115 and on on other architectures.
116 Dualhead Note: The video BIOS on some laptops interacts strangely with
119 dualhead. This can result in flickering and problems changing modes on
120 crtc2. If you experience these problems try toggling your laptop's
121 video output switch (e.g., fn-f7, etc.) prior to starting X or switch
122 to another VT and back.
