Reverted darwin/bundle/**/Credits.rtf to XFree86 versions to avoid
future conflicts on ASCII but not humal readable files. (There should
probably be separate CreditsXorg.rtf files) (Egbert Eich).

This chipset driver does not provide a graphics adaptor driver, but instead
|
|
registers a number of generic Xv adaptors which can be used with any graphics
|
|
chipset driver.
|
|
|
|
In order to use v4l adaptors with your favourite graphics driver, the
|
|
graphics driver must do two things:
|
|
|
|
1. Correctly set pScrn->memPhysBase and pScrn->fbOffset for the screens that
|
|
it provides, to the physical address of the frame buffer memory, and
|
|
the offset within that memory that the current mode starts,
|
|
respectively.
|
|
|
|
2. Use the xf86XVListGenericAdaptors() routine to list all available Xv
|
|
adaptors which are usable with any target device, and initialise
|
|
them on its screens with xf86XVScreenInit() as follows...
|
|
|
|
{
|
|
XF86VideoAdaptorPtr *ptr;
|
|
|
|
int xvexts = xf86XVListGenericAdaptors(&ptr);
|
|
|
|
if (xvexts) {
|
|
xf86XVScreenInit(pScreen, ptr, xvexts);
|
|
}
|
|
}
|
|
|
|
|
