APIC with SIS
Hello,
can any kind soul tell me the chances for implementation of:
<6>PCI: Using IRQ router SIS [1039/0008] at 00:01.0 <6>SiS pirq: advanced IDE/ACPI/DAQ mapping not yet implemented
in 2.4 ?
This message shows up if enabling APIC on boards with SIS630 chipset.

You need some kernel patches, updated ACPI and ACPI enabled to use the SIS APIC in this setup

Thanks for your quick answer.

Current ACPI is on sourceforge. The SIS APIC workaround bits haven't yet been backported to 2.4, so you either do the backport or wait 8)

Ok, so I took ACPI from sf and voila: it works now! I took the patch for 2.4.20 and it does fine. Are there chances to include this in the mainstream? Without my SIS-based motherboards do not work at all with shared interrupts (which you actually cannot prevent due to lacking bios support for pci-irq mapping).
BTW: I tried 2.4.21-pre[1-3] and none did work, of course.

You may be able to disable the APIC in the BIOS. One of my new Sis boards gave this option and it is an ok workaround for now at least.
Unfortunately it is not. Shared interrupts do _not_ work with APIC disabled. They _only_ work with APIC enabled in BIOS _and_ APIC support patch from sf. I tested every other combination and none did work.

It looks like I managed to set something to turn shared interrupts off too (because initially I was getting the shared int hang). Cant look in the BIOS right now...
You don't have to, just look at cat /proc/interrupts to see if some are shared ...

SiS APIC is not supported in 2.4. That it happens to work on your board with ACPI is I suspect mostly luck
