The most recent VIA IRQ quirk changes have broken various VIA devices for some users. We are not able to add these devices to the blacklist as they are also available in PCI-card form, and running the quirk on these devices brings us back to square one (running the VIA quirk on non-VIA boards where the quirk is not needed). This patch, based on suggestions from Sergey Vlasov, implements a scheme similar to but more restrictive than the scheme we had in 2.6.16 and earlier. It runs the quirk on all VIA hardware, but *only* if a VIA southbridge was detected on the system. To further reduce the amount of quirked devices, this patch includes a change suggested by Linus at http://lkml.org/lkml/2005/9/27/113 This ensures that devices bound to non-legacy IO-APIC interrupt lines are not quirked. We have made one change to Linus' suggestion: we do a comparison of ">15" rather than ">=15", as 15 is still in the legacy interrupt range. There is still a downside to this patch: if the user inserts a VIA PCI card into a VIA-based motherboard, in some circumstances the quirk will also run on the VIA PCI card. This corner case is hard to avoid. Signed-off-by: Daniel Drake <dsd@gentoo.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> |
