Hey,
I'm testing if_bge on my new Alchemy PCI code, and I'm getting some
interesting errors. One is a panic in bus_dmamap_sync, due to the len
argument being zero. This is an #ifdef DIAGNOSTIC check in the MIPS
bus_dma implementation.
So, either bge is doing something bad and calling this with a zero
length, or the bus_dma implementation is broken because a zero length is
legal.
So, which is it? Which place do I fix? The man page was not helpful in
clearing up what the valid inputs are.
