- iommu/vt-d: add quirk for broken interrupt remapping on 55XX chipsets
-
- A few years back intel published a spec update:
- http://www.intel.com/content/dam/doc/specification-update/5520-and-5500-chipset-ioh-specification-update.pdf
-
- For the 5520 and 5500 chipsets which contained an errata (specificially errata
- 53), which noted that these chipsets can't properly do interrupt remapping, and
- as a result the recommend that interrupt remapping be disabled in bios. While
- many vendors have a bios update to do exactly that, not all do, and of course
- not all users update their bios to a level that corrects the problem. As a
- result, occasionally interrupts can arrive at a cpu even after affinity for that
- interrupt has be moved, leading to lost or spurrious interrupts (usually
- characterized by the message:
- kernel: do_IRQ: 7.71 No irq handler for vector (irq -1)
-
- There have been several incidents recently of people seeing this error, and
- investigation has shown that they have system for which their BIOS level is such
- that this feature was not properly turned off. As such, it would be good to
- give them a reminder that their systems are vulnurable to this problem. For
- details of those that reported the problem, please see:
- https://bugzilla.redhat.com/show_bug.cgi?id=887006
