Folks,
I've got a problem in allocating DMA memory on ARM for a driver on 2.6.19:
The function snd_malloc_dev_pages requests memory using the
dma_alloc_coherent function on line 222 of sound/core/memalloc.c. This
allocation is done with the bit __GFP_COMP set, which throws an oops in
the ARM memory allocation __dma_alloc. My understanding from speaking
with Russell King is that __GFP_COMP should never be specified when
calling dma_alloc_coherent.
Is this a bug?
Cheers,
-Brett
