Hi all,
this patch series is just a couple of fixes for swiotlb-xen.
In particular the slow path (bouncing on the swiotlb buffer for dma
operations) on ARM has two problems, each of them fixed by a separate
patch:
- a xen_dma_map_page call is missing in xen_swiotlb_map_sg_attrs;
- dma_capable often fails on ARM because devices don't set the dma_mask
correctly. This causes swiotlb-xen to take the slow path, and that is
bad enough, but in xen_swiotlb_map_page also causes the function to
return an error an fail.
Stefano Stabellini (2):
swiotlb-xen: add missing xen_dma_map_page call
swiotlb-xen: xen_swiotlb_map_page: do not error out if dma_capable fails
