Author + + + ______________________________________________________________________ + + [1m1. Introduction[0m + + This document provides a brief summary of the i810/i815 support + provided by the i810 driver. Support for later chipsets is not + covered here. More up to date information about the i810 driver can + be found in the i810(4) manual page. + + + [1m2. Supported Hardware[0m + + + +o Intel 810 motherboards: + + +o i810, + + +o i810-dc100, + + +o i810e + + +o i815 + + + + [1m3. Features[0m + + + +o Full support for 8, 15, 16, and 24 bit pixel depths. + + +o Hardware cursor support to reduce sprite flicker. + + +o Hardware accelerated 2D drawing engine support for 8, 15, 16 and 24 + bit pixel depths. + + +o Support for high resolution video modes up to 1600x1200. + + +o Fully programmable clock supported. + + +o Robust text mode restore for VT switching. + + + + [1m4. Technical Notes[0m + + + +o Hardware acceleration is not possible when using the framebuffer in + 32 bit per pixel format, and this mode is not supported by this + driver. + + +o Interlace modes cannot be supported. + + +o This driver currently only works for Linux/ix86 and recent versions + of FreeBSD. It requires the agpgart kernel support, which is + included in Linux kernels 2.3.42 and higher, and FreeBSD 4.1 and + higher. + + + + [1m5. Reported Working Video Cards[0m + + + +o Intel evaluation hardware - i810, i810-dc100, i810e and i815. + + +o Tyan Tomcat Motherboard. + + +o HappyPC set-top box. + + + + [1m6. Configuration[0m + + The driver auto-detects all device information necessary to initialize + the card. The only lines you need in the "Device" section of your + xorg.conf file are: + + Section "Device" + Identifier "Intel i810" + Driver "i810" + EndSection + + + or let xorgconfig do this for you. + + However, if you have problems with auto-detection, you can specify: + + +o DacSpeed - in MHz + + +o MemBase - physical address of the linear framebuffer + + +o IOBase - physical address of the memory mapped IO registers + + In order to use most resolutions, it is necessary to install the (see + the notes in the module). + + Note: the i810 driver detects whether your motherboard has display + cache video memory. This memory is has reduced bandwidth compared to + normal system memory, and isn't used by the server. The main function + of this memory is for ancillary buffers (eg. z buffer) in a + forthcoming 3d capable server. + + + + [1m7. Driver Options[0m + + + +o "NoAccel" - Turn off hardware acceleration + + + +o "SWCursor" - Request a software cursor (hardware is default) + + +o "Dac6Bit" - Force the use of a 6 Bit Dac (8 Bit is the default) + + + [1m8. Known Limitations[0m + + + +o No 3D support in this release. + + +o Running two X servers on different VTs is not supported at this + time. + + + + [1m9. Author[0m + + + +o Keith Whitwell + + The X11R6.8 version of this driver originally came from XFree86 4.4 + rc2. + + The XFree86 version of this driver was donated to The XFree86 Project + by: + + Precision Insight, Inc. + Cedar Park, TX + USA + + + + http://www.precisioninsight.com + + + |
