Subject: PCI vector and ACPI
Date: Sat, 10 Jan 2004 17:12:33 +0200 [thread overview]
Message-ID: <40001661.90705@kolumbus.fi> (raw)
There seems to be some bad interaction between PCI VECTOR
(use_pci_vector()) and ACPI PRTs. Namely, both mp_parse_prt() and
pcibios_fixup_irqs() do the IO_APIC_VECTOR() translation on irq, the
result being IO_APIC_VECTOR(IO_APIC_VECTOR(irq)). I wonder if this is
the cause of some bug reports with acpi and pci vector? Maybe
mp_parse_prt() should not do the irq->vector translation?
