Re: [PATCH 1/5] m68k/atari: EtherNAT - change number of Atari interrupts to make room for EtherNAT interrupts
|[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]|
Part 1 (this): make room for the EtherNAT interrupts - they appear at vectors 0xc3 (USB ISP1160) and 0xc4 (SMC91C111)Is there any specific reason you cannot use atari_register_vme_int(), like drivers/net/ethernet/amd/atarilance.c, to avoid increasing NR_IRQS?
From what I read in atari_register_vme_int(), it returns the next free
VME interrupt starting at VME_SOURCE_BASE. This required the vector number to be programmable in the correspomding VME device. To the best of my knowledge, vector numbers are fixed (0xc3 and 0xc4) for the EtherNAT. I definitely need to increase NR_IRQS - it might be better to leave VME_MAX_SOURCES unchanged and change the NUM_ATARI_SOURCES definition above instead. I'm uncertain whether the complicated definition of NUM_ATARI_SOURCES is needed anymore - are the IRQ_VECTOR_TO_SOURCE and IRQ_SOURCE_TO_VECTOR macros still used anywhere?
