These two patches implement some changes in behavior related to PCI MMCONFIG configuration space access. One changes the way in which we validate the MCFG table provided by the BIOS by checking it against ACPI motherboard resources instead of the E820 table. The BIOS is not required to reserve this area in the E820 table, so checking that results in MMCONFIG being unnecessarily disabled on some machines.
Some Intel chipsets where MMCONFIG was being disabled previously (but won't be with the first patch) had problems, not due to the MCFG table being broken, but because the access was hosed by the way in which we do PCI BAR sizing. The second patch fixes this problem. This is requested for inclusion in the -mm tree for testing. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
