Hi!
I am asking once more for help with IRQ setup for Cardbus controller on ATI U1/Ali 1535+ chipset. This time with more exact information. This is what I get:
lspci -v -s 00:0a.0 00:0a.0 CardBus bridge: O2 Micro, Inc.: Unknown device 6972 Subsystem: Hewlett-Packard Company: Unknown device 0024 Flags: bus master, slow devsel, latency 32, IRQ 5 Memory at 80000000 (32-bit, non-prefetchable) [size=4K] Bus: primary=00, secondary=02, subordinate=05, sec-latency=32 Memory window 0: 81000000-81100000 I/O window 0: 00003000-0000307f I/O window 1: 00000000-00000003 16-bit legacy interface ports at 0001
Which is consistent with Windows IRQ 5
But dump_pirq gives: Interrupt routing table found at address 0xfdf10: Version 1.0, size 0x00d0 Interrupt router is device 00:07.0 PCI exclusive interrupt mask: 0x0000 [] Compatible router: vendor 0x10b9 device 0x1533 ....(skipped)
Device 00:0a.0 (slot 0): CardBus bridge INTA: link 0x06, irq mask 0x00a0 [5,7]
Device 00:12.0 (slot 0): Ethernet controller INTA: link 0x02, irq mask 0x0880 [7,11]
Device 00:0c.0 (slot 0): INTA: link 0x03, irq mask 0x0658 [3,4,6,9,10]
Interrupt router at 00:07.0: AcerLabs Aladdin M1533 PCI-to-ISA bridge INT1 (link 1): irq 10 INT2 (link 2): irq 11 INT3 (link 3): unrouted INT4 (link 4): unrouted INT5 (link 5): unrouted INT6 (link 6): irq 11 INT7 (link 7): irq 3 INT8 (link 8): irq 5 Serial IRQ: [enabled] [continuous] [frame=21] [pulse=12]
So INT6 instead of 5 gets 11 but it is not shown in lspci.
Could somebody, please, tell me what and where should be fixed (I guess in pci-irq.c) to get it correct.
BR,
