[Xen-devel] [PATCH v2 0/2] XEN SWIOTLB for ARM dma operations extension

[Andrii Anisov <andrii.anisov@xxxxxxxxx>]

From: Andrii Anisov <andrii_anisov@xxxxxxxx>

Some drivers need additional dma ops to be provided by xen swiotlb. Because
common operations implementation came from x86 world and does not suite ARM
needs we have to provide needed XEN SWIOTLB for ARM callbacks.

dma_mmap patch is a port of an antique and lost patch discussed here:
http://marc.info/?l=xen-devel&m=139695901430667&w=4

Changes in V2:
 - patches are rebased and checked for compilation for x86, arm, arm64 with
   the current LK master HEAD 83346fbc07d267de777e2597552f785174ad0373

Andrii Anisov (1):
  swiotlb-xen: implement xen_swiotlb_get_sgtable callback

Stefano Stabellini (1):
  swiotlb-xen: implement xen_swiotlb_dma_mmap callback
