Hello I am using linux kernel 2.4.2_hhl20 (pre 2.0 CDK) with a custom modified arch/ppc/kernel/ppc4xx_pic.c so that it uses level, positive interrupts. Note, I have tweaked the mtdcr calls so it modifies UIC0_PR, TR, and CR to match our hardware. With that said, why does cat /proc/interrupts say that I am using Edge Sensitive interrupts when I have modified the TR register to be Level sensitive?
I am asking this, because I have a problem where I am missing interrupts when they are generated quickly. I am hoping that the /proc/interrupts mismatch is a clue that I have not completed the Edge to Level interrupt modification. If you know of a file besides ppc4xx_pic.c which needs to be modified, please let me know. John ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
