A couple of comments: - Isn't there an "official" or standards-defined name for this capability? If so, would it be a better choice for the command line option? - The comment in iommu.c should be more verbose (and this and the other options should be added to docs/vtd.txt) and say something to the effect of "...for Dom0 for devices that have the <real name per above> capability." Otherwise, ACKed-by: Joseph Cihula <joseph.cihula@xxxxxxxxx> Joe -----Original Message----- From: Han, Weidong Sent: Wednesday, September 10, 2008 2:07 AM To: 'Xen-devel@xxxxxxxxxxxxxxxxxxx' Cc: Kay, Allen M; Cihula, Joseph Subject: [Xen-devel] [PATCH] [VTD] Add a command line param to enable/disable pass-through feature Taking security into accout, it's not suitable to bypass VT-d translation for Dom0 by default when the pass-through field in extended capability register is set. This feature is for people/usages who are not overly worried about security/isolation, but want better performance. This patch adds a command line param that controls if it's enabled or disabled.
