The PCI device intterupt is routed to IRQ 0 in Jetson Xavier 5.10 kernel

Mar 04, 2024

We found that the same error occured in L4T 35.1.


The PCI device intterupt is routed to IRQ 0.


0005:05:00.0 Multimedia controller: Contec Co., Ltd Device 8613

Control: I/O- Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-

It seems that pci_fixup_irqs() no longer exists in 5.10 kernel.


Could you please tell us how to fix it?
