[Xen-devel] [PATCH v10 00/11] Enable Memory Bandwidth Allocation in Xen

[Yi Sun <yi.y.sun@xxxxxxxxxxxxxxx>]

Hi, all,

We plan to bring a new PSR (Platform Shared Resource) feature called
Intel Memory Bandwidth Allocation (MBA) to Xen.

Besides the MBA enabling, we change some interfaces to make them more
general but not only for CAT.

The first 5 patches of V9 haven been merged. To fix a few issues, the
V10 is submitted.

Any comments are welcome!

BRs,
Sun Yi
