The problems of development at the bleeding edge. Would you rather Linux
sat on the sidelines until there are enough Google hits from other users of
new features?
I did get one hit for a search for: intel "resource director technology" ... but
it only has one line in a table with a 50,000' view of what it does.
http://www.intel.com/content/dam/www/public/us/en/documents/guides/xeon-intel-server-processor-comparison-guide.pdf
Technology: Intel Resource Director Technology
Description: Allows the hypervisor to monitor Last Level Cache usage at the application
and VM levels.
Benefit: Helps to improve performance and efficiency by providing better
information for scheduling, load balancing, and workload migration
Which isn't any help in evaluating this patch series :-(
