What do you mean? By definition the subtractive port takes all unclaimed cycles. There should be a LPC or ISA bridge in the southbridge that forwards cycles that the legacy southbridge devices don't claim. > - Is one needed if subtractive resources are implemented correctly? I don't think so. You might need to track the the subtractive bit in the bridges so you don't try to add those resources to the bridge BAR. > - Who is responsible for setting the top of the address range? This should be set per mainboard but the chipset will probably have them most influence on the value. #define DEVICE_MEM_HIGH 0xFEBFFFFFUL is probably ok for most systems but an easy way to override it would be good. > - From an earlier thread with Carl-Daniel it sounded like there are fixed > locations for APICs that need to be avoided. Where should these be avoided? Yes, APICs are generally at FEC00000(IO) and FEE00000(local). Marc -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
