Subject: use of struct hvm_irq_dpci in pv guests
Date: Thu, 31 Mar 2011 13:31:31 +0100 [thread overview]
Message-ID: <4D94904302000078000395FA@vpn.id2.novell.com> (raw)
The per-domain pointer to this is stored in ->arch.hvm_domain.irq.dpci,
hence suggesting that this is a HVM only field.
do_domctl(XEN_DOMCTL_bind_pt_irq) and domain_get_irq_dpci()
access it however without considering HVM-ness. In the course of
splitting/shrinking struct domain, I'd therefore need to know whether
this field ought to become common, or whether all accessors of the
field need to get protected by is_hvm_domain().
Thanks, Jan
