[Xen-devel] [PATCH v9 00/16] 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.

Any comments are welcome!

You can find this series at:

This version has been rebased onto latest staging branch with commit 6ccf25.

BRs,
Sun Yi
