From 426b3b8d535e3e141331dc19c40f457b997c4d6d Mon Sep 17 00:00:00 2001 From: Stefan Assmann Date: Wed, 11 Jun 2008 16:35:16 +0200 Subject: pci: add quirk to disable boot interrupt generation on intel 6300ESB Add a quirk to disable legacy boot interrupt generation on intel devices that support disabling it. This patch benefited from discussions with Alexander Graf, Torsten Duwe, Ihno Krumreich, Daniel Gollub, Hannes Reinecke.

On chipsets where this INTx generation cannot be disabled, we reroute the valid interrupts to their legacy equivalent to get rid of spurious interrupts that might otherwise bring down (vital) interrupt lines through spurious interrupt detection in note_interrupt().

From: Stefan Assmann Subject: Introduce config option for pci reroute quirks The config option X86_REROUTE_FOR_BROKEN_BOOT_IRQS is introduced to enable (or disable) the redirection of the interrupt handler to the boot interrupt line by default. Depending on the existence of interrupt masking / threaded interrupt handling in the kernel (vanilla, rt, ...) and the maturity of the rerouting patch, users can enable or disable the redirection by default. This means that the reroute quirk can be applied to any kernel without changing it. Interrupt sharing could be increased if this option is enabled. However this option is vital for threaded interrupt handling, as done by the RT kernel. It should simplify the consolidation with the RT kernel. The option can be overridden by either pci=ioapicreroute or pci=noioapicreroute.
