can you copy irq_tables to 0xf0000 on your mainboard?

It depends on the chipset on the mainboard and also if the code for that chipset sets up 0xf0000 as 'shadow memory'.
For most platforms, the answer is still 'no'. But for most platforms, I think the answer could be 'yes'

for mainboards that can't copy irq_routing_table to 0xf0000, what should we do to let linux setup irq of pci device correctly?

make sure that CONFIG_COMPRESS=0 ron
Zhu,
for mainboards that can't copy irq_routing_table to 0xf0000, what should we do to let linux setup irq of pci device correctly?
Have you checked if CONFIG_COMPRESS is set 0?
-Andrew
yes , CONFIG_COMPRESS=0 but it seems there is no effect, should i set kernel pci access mode to any or direct? "Ronald G. Minnich" rminnich@lanl.gov wrote:On Tue, 25 Feb 2003, zhu shi song wrote:

PCI access mode has to be direct.

no any progress. linux can't assign pci irq. what's wrong? Andrew Ip aip@cwlinux.com wrote:

usb's irq is still incorrect. under normal linux, usb's irq is 15, but under linuxbios the irq is 10. so usb can't work correctly. what's the correct step to run getpir? what's the rule for linux kernel to assign pci irq according to irq routing table? thanks zhu shi song zhushisongzhu@yahoo.com wrote:

should not matter for IRQ, but try direct anyway.

send the output of your serial port one more time, sorry, I"ve lost context.

Is this, by any chance, the error in which the USB hardware is not being enabled?

There is a chance that the PIR on the standard BIOS is wrong!
This happens. We've seen cases where the BIOS settings do not agree with the PIR settings, and the BIOS is just setting in the correct interrupt.
What board is this again (Sorry I forgot)
