You can use LXR to search for stuff (it's a fully cross referenced index into the kernel code): http://lxr.linux.no/linux >From this, I searched for do_IRQ against kernel version 2.6.39 and it appears to have been made architecture specific rather than being generic. Some architectures, like ARM, have an asm_do_IRQ rather than do_IRQ. -- Dave Hylands Shuswap, BC, Canada http://www.davehylands.com _______________________________________________ Kernelnewbies mailing list [email protected] http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
