Subject: [PATCH V1 00/21] x86/cqm3: Resctrl based cqm
Date: Mon, 26 Jun 2017 11:55:47 -0700 [thread overview]
Message-ID: <1498503368-20173-1-git-send-email-vikas.shivappa@linux.intel.com> (raw)
Sending a version of resctrl based cqm and mbm patches as per the
requirements discussed here:
https://marc.info/?l=linux-kernel&m=148891934720489
Several attempts were made to fix the existing upstream perf based cqm
but were NACKed by the community which led to the above discussions.
Patches are based on 4.12-rc4.
Acknowledgements:
- Thanks to Thomas for all the feedback on the requirements and design.
- Thanks to Stephane Eranian <eranian@google.com> and David
Carrillo-Cisneros <davidcc@google.com> for going through all the
churning during requirements and design phase and code reviews.
- Thanks to "Chatre, Reinette" <reinette.chatre@intel.com> for bringing up
issues in code organization and other issues in declaring globals which
were not static.
Summary of the changes -
01/21 - Remove the existing perf based cqm
02/21 - A fix to existing RDT memory leak issue
03/21 - Documentation for resctrl based cqm
04 - 06/21 - Cleanup/Preparatory patches for resctrl based cqm
07 - 18/21 - Add CQM support
19 - 21/21 - Add MBM support
