Hi Stefano, First off, apologies for bumping this dead thread. I came across this patch signed off by you recently https://github.com/Xilinx/linux-xlnx/commit/72cb5514953be3aa2ac00c57c9eaa100ecc67176 and was wondering if a patch replacing xen_domain() with xen_pv_domain() in vring_use_dma_api() can be sent upstream? If not, is there a reason why? Regards Amneesh
