* [PATCH] i40e: support xen domain0 @ 2014-08-14 6:12 Helin Zhang [not found] ` <1407996773-7055-1-git-send-email-helin.zhang-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org> 0 siblings, 1 reply; 4+ messages in thread From: Helin Zhang @ 2014-08-14 6:12 UTC (permalink / raw) To: dev-VfR2kkLFssw i40e was failing to run in XEN domain0, as the physical memory for adminq DMA should be allocated and translated in a different way for XEN domain0. So rte_memzone_reserve_bounded() should be used for DMA memory allocation, and rte_mem_phy2mch() should be used for DMA memory address translation to support running i40e PMD in XEN domain0.
