lparstat: Fix display of mode for dedicated-donating partition
From the lparstat man page:
mode
Indicates whether the partition processor capacity is capped or uncapped
allowing it to consume idle cycles from the shared pool. Dedicated LPAR
is capped or donating.
However, on a dedicated partition, lparstat always displays the mode as
'Capped' today. Fix this by using 'DedDonMode' field from lparcfg for
determining the cycle donation status of a dedicated partition.
On a dedicated-donating partition:
$ grep -e shared -e DedDonMode -e capped /proc/powerpc/lparcfg
DedDonMode=1
capped=1
shared_processor_mode=0
Before this patch:
$ lparstat
System Configuration
type=Dedicated mode=Capped smt=8 lcpu=1 mem=3335424 kB cpus=0 ent=1.00
After this patch:
$ lparstat
System Configuration
type=Dedicated mode=Donating smt=8 lcpu=1 mem=3335424 kB cpus=0 ent=1.00
