Relevant is whether the card * occupies the A0000 area at this time. Assuming (?) * that this does not change during machine up-time, * it suffices to know which device was the boot video * device (as determined by Linux 2.6.12 and later). * Also, this is only relevant if the card is in text * mode; if it's in graphics mode, fonts aren't saved * or restored anyway. * sisfb tells us if that card is considered the boot * video device. The hardware registers tell us if * the card's A0000 address decoding is enabled, and if * the card currently is in text mode. These three bits * of information are enough to decide on whether or not * to save/restore fonts. * 2) POSTing. Same here. Relevant is only whether or not * the card has been POSTed once before. POSTing cards * on every server start is pretty ugly, especially * if a framebuffer driver is already handling it. * SiS/XGI cards POSTed by sisfb can coexist well with other * active adapters. So we trust sisfb's information more * than X's (especially as we only use this information for * console font restoring and eventual POSTing.) * What we still need is a way to find out about all this if * sisfb is not running.... */ if(!pSiS->Primary && pSiS->sisfbprimary) { xf86DrvMsg(pScrn->scrnIndex, X_PROBED, "sisfb reports this adapter to be primary.
