Hello,

On IBM Power paltform , add cpu entitlement can not be done  without LPARCFG=Y , because /proc/ppc64/lparcfg could not open: 
Logs from drmgr :
########## Apr 03 10:54:41 2024 ##########
drmgr: -c cpu -r -q 10 -p ent_capacity -w 5 -d 1
Validating CPU DLPAR capability...yes.
Could not open "/proc/ppc64/lparcfg"
No such file or directory
CPU entitlement capability is not enabled on this platform.
Could not update system parameter ent_capacity
########## Apr 03 10:54:41 2024 ##########

will the LPARCFG option be activated on future versions?

Best Regards,
Thomas.

Since this is obviously something that needs to be changed in the kernel configuration, the bug should be reported against src:linux and not against the powerpc-utils package.

Thanks,
Adrian
