Bjorn Helgaas d558b483d5 x86/PCI: truncate _CRS windows with _LEN > _MAX - _MIN + 1 ... Yanko's GA-MA78GM-S2H (BIOS F11) reports the following resource in a PCI host bridge _CRS: [07] 32-Bit DWORD Address Space Resource Min Relocatability : MinFixed Max Relocatability : MaxFixed Address Minimum : CFF00000 (_MIN) Address Maximum : FEBFFFFF (_MAX) Address Length : 3EE10000 (_LEN) This is invalid per spec (ACPI 4.0, 6.4.3.5) because it's a fixed size, fixed location descriptor, but _LEN != _MAX - _MIN + 1. Based on https://bugzilla.kernel.org/show_bug.cgi?id=15480#c15, I think Windows handles this by truncating the window so it fits between _MIN and _MAX. I also verified this by modifying the SeaBIOS DSDT and booting Windows 2008 R2 with qemu. This patch makes Linux truncate the window, too, which fixes: http://bugzilla.kernel.org/show_bug.cgi?id=15480 Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Tested-by: Yanko Kaneti <yaneti@declera.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>		15 years ago
