[PATCH v2 0/3] x86/ioreq: Extend ioreq server to support multiple ioreq pages

Posted by Julian Vetter 1 month, 3 weeks ago

Hello Jan and Andrew,
I have adressed your feedback and replaced the for loop with
xvzalloc_array() in ioreq_server_alloc_mfn. This indeed simplifies the
code in that function. I have also addressed the other points
(indentation patch, blank lines, etc.). I just couldn't come up with a
better solution for the struct ioreq_server. We now have a new member
ioreq_gfn, to track the guest frame number. Any thoughts on this?
