Hi All, Here is v7 of my patch to address the E820 reservations vs PCI host bridge ranges issue which are causing touchpad and/or thunderbolt issues on many different laptop models. After previous attemps to identify these systems by looking for E820 reservations covering the entire bridge window, which broke the boot on some coreboot based ChromeBooks we are now back to using a bios date based approach, now combined with DMI quirks for systems after the cutoff date which still report a wrong window from their _CRS method despite them being new(ish). This is based on top of Bjorn's pci/resource branch: https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/log/?h=pci/resource Regards, Hans Hans de Goede (1): x86/PCI: Ignore E820 reservations for bridge windows on newer systems .../admin-guide/kernel-parameters.txt | 9 +++ arch/x86/include/asm/pci_x86.h | 2 + arch/x86/pci/acpi.c | 74 ++++++++++++++++++- arch/x86/pci/common.c | 6 ++ 4 files changed, 89 insertions(+), 2 deletions(-) -- 2.36.0
