Subject: [PATCH v2 0/2] fix and cleanup for iommu/vt-d
Date: Fri, 27 May 2016 22:24:06 +0000 [thread overview]
Message-ID: <1464387848-16942-1-git-send-email-richard.weiyang@gmail.com> (raw)
The first patch tries to improve the calculation of the dmar_domain first
level entry.
The second patch defines two marco for dmar_domains second level size and
shift instead of using an integer.
---
v2:
* use DIV_ROUND_UP instead of ALIGN for the calculation.
Thanks Robin Murphy <robin.murphy-5wv7dgnIgG8@public.gmane.org>
