| Subject: PCI: Add new ID for Intel GPU "spurious interrupt" quirk |
| |
| From: Thomas Jarosch <thomas.jarosch@intra2net.com> |
| |
| commit 7c82126a94e69bbbac586f0249e7ef11e681246c upstream. |
| |
| After a CPU upgrade while keeping the same mainboard, we faced "spurious |
| interrupt" problems again. |
| |
| It turned out that the new CPU also featured a new GPU with a different PCI |
| ID. |
| |
| Add this PCI ID to the quirk table. Probably all other Intel GPU PCI IDs |
| are affected, too, but I don't want to add them without a test system. |
| |
| See f67fd55fa96f ("PCI: Add quirk for still enabled interrupts on Intel |
| Sandy Bridge GPUs") for some history. |
