If so, can someone help me > in understanding why these interrupts come and how to resolve it ? You'll need to tell us what platform you're running on. The BAD interrupts come from ppc_spurious_interrupts. It's a count of the number of times we entered do_IRQ() (ie. took an external interrupt), but when we asked the interrupt controller which irq it was, the interrupt controller said there was no irq. Depending on your interrupt controller that might happen sometimes for valid reasons. Or it might indicate something is setup wrong. cheers [-- Attachment #2: This is a digitally signed message part --] [-- Type: application/pgp-signature, Size: 197 bytes --] ^ permalink raw reply [flat|nested] 6+ messages in thread

The test scenario forwarding application and is a bidirectioanl flow between eth0 & eth2. Attached is the complete log of the test scenario. I also noted another observation that when all the interrupts are mapped to a single core, the BAD interrupts stop coming. -- Thanks Sandeep [-- Attachment #2: smp_log_bad_intrs.txt --] [-- Type: text/plain, Size: 27221 bytes --] tftp 1000000 etsec2/uImage_alpha Speed: 1000, full duplex Using eTSEC1 device TFTP from server 10.232.134.194; our IP address is 10.232.133.188 Filename 'etsec2/uImage_alpha'.

This seems to come from the gianfar and: - when we are binding the three interruptions enet_tx, enet_rx and enet_err of each interfaces on the same processor, the BAD interruptions do not increase any more. - when we are compiling the driver without the NAPI mode, there is no more BAD interruptions at all. Hope it will help even if we did not find a real fix. Regards. Régis.

* [HELP] BAD interrupts @ 2009-12-23 14:17 Kumar Gopalpet-B05799 0 siblings, 0 replies; 6+ messages in thread From: Kumar Gopalpet-B05799 @ 2009-12-23 14:17 UTC (permalink / raw) To: netdev Hi all, I am trying linux 2.6.32-rc3 in SMP mode. I am seeing a lot of BAD interrupts when I do a "cat /proc/interrupts". I am running a forwarding application b/w two ethernet ports (ethernet uses gianfar driver). Has any one observed these BAD interrupts ? If so, can someone help me in understanding why these interrupts come and how to resolve it ? -- Thanks Sandeep ^ permalink raw reply [flat|nested] 6+ messages in thread
