Subject: No interrupts for PCMCIA cards
Date: Sun, 04 Apr 2004 21:51:05 +0200 [thread overview]
Message-ID: <1081108265.5533.17.camel@pegasus> (raw)
Hi guys,
while trying to fix a problem with a Bluetooth PCMCIA card I faced the
problem that my Cardbus controller don't give out any interrupts. I
tried it with 2.6.5 and this is my PCMCIA bridge:
0000:02:0e.0 CardBus bridge: Texas Instruments PCI1410 PC card Cardbus Controller (rev 01)
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR-
Latency: 168, Cache Line Size: 0x20 (128 bytes)
Interrupt: pin A routed to IRQ 18
Region 0: Memory at 20000000 (32-bit, non-prefetchable)
Bus: primary=02, secondary=04, subordinate=07, sec-latency=176
Memory window 0: 20400000-207ff000 (prefetchable)
Memory window 1: 20800000-20bff000
I/O window 0: 00004000-000040ff
I/O window 1: 00004400-000044ff
BridgeCtl: Parity- SERR- ISA- VGA- MAbort- >Reset+ 16bInt+ PostWrite+
16-bit legacy interface ports at 0001
And this is how /proc/interrupts look like:
CPU0
0: 7241752 IO-APIC-edge timer
1: 10923 IO-APIC-edge i8042
2: 0 XT-PIC cascade
8: 4 IO-APIC-edge rtc
12: 94 IO-APIC-edge i8042
14: 134100 IO-APIC-edge ide0
15: 1 IO-APIC-edge ide1
18: 0 IO-APIC-level yenta
19: 120010 IO-APIC-level uhci_hcd
20: 0 IO-APIC-level ohci_hcd
21: 231886 IO-APIC-level ohci1394, ohci_hcd, eth0
22: 297 IO-APIC-level acpi, ehci_hcd
23: 57 IO-APIC-level aic7xxx, uhci_hcd
NMI: 0
LOC: 7241898
ERR: 0
MIS: 0
The count for interrupt 18 is still zero every time, but on my Sony C1VE
laptop the PCMCIA cards get their interrupts.
Regards
Marcel
