Yep. I even thought about this but decided not to do... can't recall why. Now I think it's really a good idea.
Maybe we should create DEFINE_ALIGNED_VARIABLE as a common.h macro?
Like what's in common.h -- ALLOC_CACHE_ALIGN_BUFFER ?
Yes, but for static variables and not hard-bound to ARCH_DMA_MINALIGN.
Hm.. Maybe. Ideas? ;) Actually I also thought about moving all this stuff to a single proper aligned buffer and do flush/invalidate for a whole buffer at once. It can save us some space... but it's BSS anyway... Don't know if it's worth it...
But if you copy stuff back and forth, it'll cause performance hit.
No, you talk about full bounce-buffering support and meant only one big buffer for internal structs.
