Hi, I have a customized Intel Denverton-NS platform similar like Harcuvar CRB. In dmesg, I can see following: [ 10.973387] ACPI: PCI Interrupt Link [LNKA] (IRQs 6 7 10 *11 12 14 15) [ 10.981587] ACPI: PCI Interrupt Link [LNKB] (IRQs 6 7 *10 11 12 14 15) [ 10.989776] ACPI: PCI Interrupt Link [LNKC] (IRQs *6 7 10 11 12 14 15) [ 10.997961] ACPI: PCI Interrupt Link [LNKD] (IRQs 6 *7 10 11 12 14 15) [ 11.006147] ACPI: PCI Interrupt Link [LNKE] (IRQs 6 7 10 11 *12 14 15) [ 11.014332] ACPI: PCI Interrupt Link [LNKF] (IRQs 6 7 10 11 12 *14 15) [ 11.022518] ACPI: PCI Interrupt Link [LNKG] (IRQs 6 7 10 11 12 14 *15) [ 11.030697] ACPI: PCI Interrupt Link [LNKH] (IRQs 6 7 10 11 12 14 *15) And by “lspci -s 00:14.0 -vv”, there is a message “Interrupt: pin A routed to IRQ 28”. Actually I know in the devicetree.cb, the device 14’s interrupt is configured by IR08 which routes INTA to PIRQE and LNKE is using IRQ12. This is the legacy interrupt mode as kernel message dumped. But in ACPI mode, why does lspci report IRQ28 and how to reconfigure it in Coreboot? Please help to clarify. Thanks.
