…ller in runc MBA Software Controller feature is introduced in Linux kernel v4.18. It is a software enhancement to mitigate some limitations in MBA which describes in kernel documentation. It also makes the interface more user friendly - we could specify memory bandwidth in "MBps" (Mega Bytes per second) as well as in "percentages". The kernel underneath would use a software feedback mechanism or a "Software Controller" which reads the actual bandwidth using MBM counters and adjust the memory bandwidth percentages to ensure: "actual memory bandwidth < user specified memory bandwidth". We could enable this feature through mount option "-o mba_MBps": mount -t resctrl resctrl -o mba_MBps /sys/fs/resctrl In runc, we handle both memory bandwidth schemata in unified format: "MB:<cache_id0>=bandwidth0;<cache_id1>=bandwidth1;..." The unit of memory bandwidth is specified in "percentages" by default, and in "MBps" if MBA Software Controller is enabled.

After talking to Rohit, he mentioned that he wasn't aware he was still a maintainer (and that his maintainership was grandfathered from his Docker maintainership). He's moved on to other projects now, and thus said he would happily step down as maintainer. (Since he's stepping down voluntarily, this doesn't require a mailing-list vote.) Thanks for all of your hard work, Rohit! Signed-off-by: Aleksa Sarai <[email protected]>
After discussion with Victor, he mentioned that he wanted to rescind his maintainership a few years ago (due to a change in priorities and what he's been working on) but wasn't sure what the right process is. Thanks for your hard work Victor! Signed-off-by: Aleksa Sarai <[email protected]>

When built with nokmem we explicitly are disabling support for kmemcg, but it is a strict specification requirement that if we cannot fulfil an aspect of the container configuration that we error out. Completely ignoring explicitly-requested kmemcg limits with nokmem would undoubtably lead to problems. Fixes: 6a2c155 ("libcontainer: ability to compile without kmem") Signed-off-by: Aleksa Sarai <[email protected]>
