16 rendition is an XFree86 driver for Rendition/Micron based video cards.
17 The driver supports following framebuffer depths: 8, 15 (Verite V1000
18 only), 16 and 24. Acceleration and multi-head configurations are not
19 supported yet, but are work in progress.
20
22 The rendition driver supports PCI and AGP video cards based on the fol‐
23 lowing Rendition/Micron chips:
24 V1000 Verite V1000 based cards.
26 V2100 Verite V2100 based cards. Diamond Stealth II S220 is the
28 only known such card.
29 V2200 Verite V2200 based cards.

33 Please refer to XF86Config(5) for general configuration details. This
34 section only covers configuration details specific to this driver.
35 The driver auto-detects the chipset type, but the following ChipSet
37 names may optionally be specified in the config file "Device" section,
38 and will override the auto-detection:
39 "v1000", "v2x00".
41 The driver will auto-detect the amount of video memory present for all
43 chips. If the amount of memory is detected incorrectly, the actual
44 amount of video memory should be specified with a VideoRam entry in the
45 config file "Device" section.
46 The following driver Options are supported:
48 Option "SWCursor" "boolean"
50 Disables use of the hardware cursor. Default: use HW-cursor.
51 Option "OverclockMem" "boolean"
53 Increases the Mem/Sys clock to 125MHz/60MHz from standard
54 110MHz/50MHz. Default: Not overclocked.
55 Option "DacSpeed" "MHz"
57 Run the memory at a higher clock. Useful on some cards with dis‐
58 play glitches at higher resolutions. But adds the risk to damage
59 the hardware. Use with caution.
60 Option "FramebufferWC" "boolean"
62 If writecombine is disabled in BIOS, and you add this option in
63 configuration file, then the driver will try to request write‐
64 combined access to the framebuffer. This can drastically
65 increase the performance on unaccelerated server. Requires that
66 "MTRR"-support is compiled into the OS-kernel. Default: Dis‐
67 abled for V1000, enabled for V2100/V2200.
68 Option "NoDDC" "boolean"
70 Disable probing of DDC-information from your monitor. This
71 information is not used yet and is only there for informational
72 purposes. This might change before final XFree86 4.0 release.
73 Safe to disable if you experience problems during startup of X-
74 server. Default: Probe DDC.
75 Option "ShadowFB" "boolean"
77 If this option is enabled, the driver will cause the CPU to do
78 each drawing operation first into a shadow frame buffer in sys‐
79 tem virtual memory and then copy the result into video memory.
80 If this option is not active, the CPU will draw directly into
81 video memory. Enabling this option is beneficial for those sys‐
82 tems where reading from video memory is, on average, slower than
83 the corresponding read/modify/write operation in system virtual
84 memory. This is normally the case for PCI or AGP adapters, and,
85 so, this option is enabled by default unless acceleration is
86 enabled. Default: Enabled unless acceleration is used.
87 Option "Rotate" "CW"
89 Option "Rotate" "CCW"
91 Rotate the display clockwise or counterclockwise. This mode is
92 unaccelerated. Default: no rotation.
93 Notes For the moment the driver defaults to not request write-combine
96 for any chipset as there has been indications of problems with
97 it. Use Option "MTRR" to let the driver request write-combining
98 of memory access on the video board.
