Re: [PATCH 0/1] x86/cqm: Cqm3 Design Documentation

[Shivappa Vikas]

Hello Thomas,

Wanted to know if you had any feedback on the new interface for cqm design which 
is based on monitoring the resctrl groups. It tries to address all the 
requirements discussed in :

https://marc.info/?l=linux-kernel&m=148891934720489

-basically to monitor resctrl groups / per thread including kernel threads.
-monitor thread from creation (also a child thread forked belongs to same group 
like its parent)
-monitor subset of tasks in a resctrl group.
-monitor subset of cpus in a resctrl group.
-monitor different events (however the first version only shows llc_occupancy)
-monitor all domains and show per domain data.

I have a patch series but was thinking to send after the design document is 
reviewed so that its easy to review and I can make changes that are discussed 
here.

Thanks,
Vikas
