Description Michal Sekletar 2019-08-13 12:32:31 UTC

Description of problem:
Currently (in systemd-243), it is possible to set NUMAPolicy= and NUMAMask= options alongside CPUAffinity= setting in unit files. It makes a lot of sense to introduce a possibility to automatically infer the appropriate value of CPUAffinity= option based on already configured NUMA options.  

Version-Release number of selected component (if applicable):
systemd-219

Actual results:
CPUAffinity= must be explicitly set up with a specific list of CPU indices 

Expected results:
CPUAffinity= can be set to the special value "numa".
