[Xen-devel] [RFC PATCH 0/1] xen: credit2: rb-tree for runqueues

[Praveen Kumar <kpraveen.lkml@xxxxxxxxx>]

Hi All,

This is the continued work with respect to rb-tree usage in Credit2, as
mentioned in previous conversations

https://lists.xen.org/archives/html/xen-devel/2017-06/msg01968.html

The patch optimized the Credit2 runqueue from sorted queue to rb-tree.
This will help in performance and scalability, when we have huge number of
vCPUs.

Please provide your comments over the changes done.

Further, I might need some assistance to run the patch with high end machines
with good amount of CPU cores. This may help to stress the code changes and
uncover any regressions when scale is in consideration.
Please do suggest if any specific test scenarios has to be tested.

Thanks in advance.

Regards,

~Praveen.
