Hi all. Is the following loop (from drivers/sound/i810_audio.c among
others) still the best way to allocate a large amount of DMA RAM for
audio? ie. for audio devices that do not support scatter-gather.
Thanks,
Jeff

for (order = DMABUF_DEFAULTORDER; order >= DMABUF_MINORDER; order--)
if ((rawbuf = pci_alloc_consistent(state->card->pci_dev,
PAGE_SIZE << order,
&dmabuf->dma_handle)))
break;
if (!rawbuf)
return -ENOMEM;
