Please, be patient and don't repost the same stuff every day.Ok. How long does it take for a patch to get included into the kernel? I posted if two weeks ago for the first time and nothing happened. In LKML also nobody answers.
That generally means nobody cares (don't worry, we've all been there). In your case, I would start by very clearly describing exactly why you can't use DMA on Pegasos, and why the current code is unusable. Can a PC floppy run in non-DMA mode? If so, your patch should probably be for floppy.c rather than asm-ppc/floppy.h . I notice there is already code for "virtual DMA mode" in floppy.c, apparently for when there is no memory available in the DMA zone. Why doesn't that code work for you? As for code style, it seems that "TRACE_FLPY_INT" is something you invented. It hurts readability; I'd remove it. Drop that "register" stuff. Make your whitespace consistent (for example, add spaces after "if" and "for"). -Hollis
