This allows quirks for non-acs capable pci devices to be applied, as pci_dev_specific_enable_acs() is now called irrespective of ACS capabilities. This results in correct isolation of PCI devices on my test machine. It would be good if Samuel or Jim can test it as well: https://download.opensuse.org/repositories/home:/vliaskovitis:/branches:/Ker... Maybe the patch can then be proposed/reviewed/improved upstream. "config_acs=pci=..." option seems to work as expected for other devices (with this patch applied), but I have not used the option extensively. -- You are receiving this mail because: You are on the CC list for the bug.
