[ACPI] irq routing problem on legacy free laptop

[Jan V. <Jan...@st...>]

Hi,

I have a toshiba satellite 5005 'legacy free' laptop.
It's BIOS is limited to only initializing the devices it needs to boot.
All other devices are left unconfigured. When reading the
PCI_INTERRUPT_LINE from their config spaces, it returns 255.
The linux kernel ignores these devices, so these become useless.

Their are only 2 solutions I can think of:
* hard-code irq numbers in linux kernel (very ugly hack)
* let acpi configure these devices (this laptop conforms to acpi 1.0b)

I tried kernel 2.4.16 with the acpi 20011205 patch.
Although I get a IRQ table printed out, the devices aren't configured.
I heard this wasn't implemented yet, so my question is:
what needs to be done, and how can I help?

Best regards,
Jan
