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);
