Subject: [RFC][PATCH 0/5] xen: reserve RMRR to avoid conflicting MMIO/RAM
Date: Thu, 7 Aug 2014 19:02:46 +0800 [thread overview]
Message-ID: <1407409371-31728-1-git-send-email-tiejun.chen@intel.com> (raw)
While we work for supporting RMRR mapping for Windows GFX driver in case
shared table,
http://osdir.com/ml/general/2014-07/msg55347.html
http://osdir.com/ml/general/2014-07/msg55348.html
we realize we should reserve RMRR range to avoid any potential MMIO/RAM
overlap with our discussion so here these preliminary patches are intended
to cover this.
----------------------------------------------------------------
Tiejun Chen (5):
xen:x86: record RMRR mappings
xen:x86: introduce a new hypercall to get RMRR mappings
tools:libxc: remove mmio BAR out of RMRR mappings
tools:firmware:hvmloader: reserve RMRR mappings in e820
xen:vtd: make USB RMRR mapping safe
