|
|
|

|
|
IMPORTANT NOTE :
|
||
|
|
----------------
|
||
|
|
- The driver name is now 'openchrome', and this is what you need to use in
|
||
|
|
your xorg.conf now (instead of 'via'). The XvMC libraries have also been
|
||
|
|
renamed, to 'libchromeXvMC.so' and 'libchromeXvMCPro.so'.
|
||
|
|
|

|
KNOWN BUGS/LIMITATIONS :
|
||
|
|
------------------------
|
||
|
|
* Laptop panel
|
||
|
|
- Laptop displays for anything other than CLE266 and KM400/P4M800 are only
|
||
|
|
supported thru VBE calls.
|
||
|
|
- Virtual terminal is broken on some laptop displays. Use a vesa framebuffer to
|
||
|
|
work around that (append vga=791 to your kernel command line, for example).
|
||
|
|
|
||
|
|
* XvMC
|
||
|
|
- The hardware MPEG4 acceleration that is present on some chipsets is not
|
||
|
|
implemented.
|
||
|
|
- No XvMC support for CX700 (new, unsupported engine).
|
||
|
|
- No XvMC support for K8M890, P4M890 and P4M900/VN896 (need to get dri working
|
||
|
|
for them first).
|
||
|
|
|
||
|
|
* TV output
|
||
|
|
- TV modes are hardcoded and must be choosen inside a list depending on the TV
|
||
|
|
encoder.
|
||
|
|
- Outputs are dependent on each other and will use the least common
|
||
|
|
denominator. If you're using both VGA/LCD output and TV output, the VGA/LCD
|
||
|
|
output will be limited by the TV encoder (720x576@50Hz for example).
|
||
|
|
In other words, there is no dual screen support.
|
||
|
|
|
||
|
|
* Misc.
|
||
|
|
- Add-on and integrated TMDS encoders are not supported, except thru VBE.
|
||
|
|
|
||
|
|
* Chrome9
|
||
|
|
- Chrome9 chipsets' family (P4M900 and K8M890) currently doesn't
|
||
|
|
support neither AGP DMA nor 3D acceleration.
|
||
|
|
|
||
|
|
|
||
|
|
Please note that 3D acceleration is provided by Mesa (http://mesa3d.org) and is
|
||
|
|
not directly related to openchrome.
