Hi All, i have a board shipped with Linux kernel 2.6.27. i have some problems in interrupts but while i was gathering some info about the interrupts on my board by
cat /proc/interrupts CPU0 16: 2525 OpenPIC Level enet_tx 17: 5606 OpenPIC Level enet_rx 18: 0 OpenPIC Level enet_error 21: 3 OpenPIC Level fsldma-channel 22: 3 OpenPIC Level fsldma-channel 23: 3 OpenPIC Level fsldma-channel 25: 3 OpenPIC Level fsldma-channel 26: 461 OpenPIC Level serial 27: 0 OpenPIC Level i2c-mpc 48: 4 OpenPIC Level phy_interrupt 50: 0 OpenPIC Edge DSP-A 52: 11 OpenPIC Edge DSP-B 54: 0 OpenPIC Level FPGA BAD: 0 actually i m interested in IRQ number 52. from the previous command: it seems to me OpenPIC has received 11 interrupt from the device namely DSP-B& this interrupt is edge triggered. Is it correct? Also i use: cat /proc/irq/52/spurious count 11 unhandled 0 last_unhandled 0 ms but actually i dont understan its meaning? does it mean that i received 11 spurious interrupt? i expect this because the name of the file is spurious. what does the field unhandled mean? thanks for ur help. -- View this message in context: http://www.nabble.com/what-is--proc-interrupts----proc-irq-*-spurious-mean--tp23918722p23918722.html Sent from the linuxppc-dev mailing list archive at Nabble.com. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
