Subject: acpi_pci_link_allocate() -- latent bug?
Date: Sat, 31 Jul 2004 22:40:07 -0400	[thread overview]
Message-ID: <410C5807.7000602@vassar.edu> (raw)


I am investigating an interrupt problem on my machine and came across 
the following code, in drivers/acpi/pci_link.c

What happens here if the BIOS sets up these links at the IRQ router at 
boot time, but doesn't restore them after a resume from S3? Is this a 
latent bug? Seems like this routine would eventually be called from 
pci_device_enable, but wouldn't perform the setup we need.

static int acpi_pci_link_allocate(struct acpi_pci_link* link) {
        int irq;
        int i;

        ACPI_FUNCTION_TRACE("acpi_pci_link_allocate");

        if (link->irq.setonboot)
                return_VALUE(0);
