what about adding a new func like: #define dma_buffer_alloca(size)
I generally avoid large allocations on the stack, they can confuse virtual stack management and blow out small embedded stacks.
oh, and that doesnt preclude also adding a dma_buffer_malloc(size). it's just that all the cases here are already on the stack, so i was focusing on that. -mike
Yup, totally reasonable. Lukasz, would you like to add the above macro to your dcache cache line size patch? Then we can change our other patches to use it instead of memalign.
Thanks, Anton
