Subject: Question on MPC83xx interrupts
Date: Tue, 22 Apr 2008 18:58:33 +0200 [thread overview]
Message-ID: <480E1939.6000701@matrix-vision.de> (raw)
All,
I'm currently running a MPC8343 based board.
Looks like I'm having problems with IRQs of a PCI device.
/proc/interrupts give :
CPU0
16: 554 IPIC Level i2c-mpc
17: 11 IPIC Level i2c-mpc
18: 134 IPIC Level ath
19: 1557 IPIC Level serial
21: 341 IPIC Level mpc83xx_spi
38: 0 IPIC Level ehci_hcd:usb1
BAD: 2
I wonder if the IRQ number should match the vector of the datasheet ...
giving :
14 -> I2C1
15 -> I2C2
16 -> SPI
38 -> USB DR
The "ath" is a PCI Ath5k WiFi module connected to IRQ1, i.e. mapped to
vector 17.
Are the IRQ numbers shifted/mapped/scrambled in any way ?
Can anyone shed some light on this ?
Cheers,
Andre Schwarz
