\uD83D\uDDE3 Discussion topics
AJB: wondered if anyone had run stuff on the xen-hv
MP: has run a bunch on x86 but not VirGL
AJB: Discussing the DMAops (https://lore.kernel.org/lkml/1650646263-22047-1-git-send-email-olekstysh@gmail.com/ )
AB: gave an overview of the the various DMA mapping stuff
CC: should look at Jurgen Xen Summit presentation
AJB: do DMA ops affect memory allocation?
AB: two APIs, one where you ask for a buffer (coherent ops interface)
AJB: does this cross sect with pKVM zero-copy?
AB: not really as dmaalloc deals with kernel memory and traditional zero-copy involves sharing user space address
AJB: pointed CC at the FEAT_LPA patches
