lparstat Displays Negative Values for %idle in "Actual" Section

[SamirMulani]

—————————Steps to reproduce the issue———————
Step 1: Boot the lpar in shared mode with any EC vs VP ratio.
Step 2: Build and run the upstream lparstat,
(https://github.com/ibm-power-utilities/powerpc-utils.git)
Step 3: Run the ebizzy workload from either LTP or from below link,
(Source 1: https://sourceforge.net/projects/ebizzy/files/ebizzy/0.3/ebizzy-0.3.tar.gz
Source 2: LTP)
Step 4: Run the command below with load.
Ex: lparstat -E 2 2

——————With ebizzy workload—————
With distro lparstat;
(lparstat - 1.3.10)

lparstat -E 2 2

System Configuration
type=Shared mode=Uncapped smt=6 lcpu=12 mem=298501056 kB cpus=34 ent=12.00

---Actual--- -Normalized-
%busy %idle Frequency %busy %idle

100.01 0.00 3.22GHz[ 93%] 93.00 0.00
100.00 0.00 3.22GHz[ 93%] 93.00 0.00

With Upstream (powerpc-utils)lparstat:
(lparstat - 1.3.13)

./lparstat -E 2 2

System Configuration
type=Shared mode=Uncapped smt=6 lcpu=12 mem=298501056 kB cpus=34 ent=12.00

---Actual--- -Normalized-
%busy %idle Frequency %busy %idle

---

101.54 -1.54 3.22GHz[ 93%] 94.44 5.19
100.39 0.00 3.22GHz[ 93%] 93.36 6.22

The logs clearly indicate that upstream powerpc-utils is having issue while showing the “Actual” %idle value, Where its showing the negative values.
