Subject: [PATCH v2 00/15] xen/arm: P2M clean-up fixes
Date: Thu, 28 Jul 2016 15:20:05 +0100 [thread overview]
Message-ID: <1469715620-4670-1-git-send-email-julien.grall@arm.com> (raw)
Hello all,
This patch series contains a bunch of clean-up and fixes for the P2M code on
ARM. The major changes are:
- Deduce the memory attributes from the p2m type
- Switch to read-write lock to improve performance
- Simplify the TLB flush for a give p2m
For all the changes see in each patch.
I have provided a branch with all the patches applied on my repo:
git://xenbits.xen.org/people/julieng/xen-unstable.git branch p2m-cleanup-v2.
Yours sincerely,
Julien Grall (15):
