Since it's hard to guess the optimal swiotlb buffer for such platforms,
I think a follow-up step would be to use the DMA coherent pool for
bouncing if no swiotlb buffer is available. At least the pool can grow
dynamically. Yet another option would be to increase the swiotlb buffer
at run-time but it has an overhead for is_swiotlb_buffer().
Alex said he wanted to look into growing the swiotlb buffer on demand
for other reason, so adding him to Cc to check if there has been any
progress on that.
Hi Alex,
Did you get a chance to look into this? If so, have you been able to
make progress on being able to grow the SWIOTLB buffer on demand?
I've been slightly under water and haven't been able to look at this yet
:). It's on my list, but will probably be a while until I get to it.
Would you be interested in having a first try?
Thanks,
Alex
