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: https://github.com/yisun-git/xen_mba mba_v9 This version has been rebased onto latest staging branch with commit 6ccf25.
