Subject: [PATCH 0/2] Fix remaining RMRR issues
Date: Thu,  1 Oct 2015 16:34:32 +0200	[thread overview]
Message-ID: <1443710074-29701-1-git-send-email-joro@8bytes.org> (raw)

Hi,

here is a patch-set to fix a remaining RMRR issue in the
VT-d driver. The problem was that RMRR mappings are only
created for boot-time (or hotplug-time) allocated domains.

Domains allocated on demand don't get RMRR mappings, which
is bad for the kdump case, for example. With this patch-set
the on-demand domains also get RMRR mappings.

Regards,

	Joerg
