           Summary: [dpdk26.07-rc1] power_intel_uncore: start
                    dpdk-l3fwd-power failed on Ubuntu26.04
           Product: DPDK
           Version: 26.07
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal

  Target Milestone: ---

Environment
===========
DPDK version: dpdk-26.07-rc1 (c429b06df56788795f8)
OS: Ubuntu 26.04 LTS/Linux 7.0.0-14-generic
Compiler: gcc version 15.2.0 (Ubuntu 15.2.0-16ubuntu1)
NIC hardware: Ethernet Controller E810-C for SFP 1593 [8086:1593 (rev 01)]
NIC firmware: 
  driver: vfio-pci
  kdriver: ice-2.6.4
  fw: 5.00 0x80021c11 1.4002.0
  ddp: ICE OS Package version 1.3.59.0

Test Setup
Steps to reproduce
==================
1.Build dpdk 
CC=gcc meson -Dlibdir=lib  --default-library=static x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc
meson configure -Dexamples=l3fwd-power x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc

2.Start dpdk-l3fwd-power
usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:38:00.0 0000:38:00.1
/root/dpdk/x86_64-native-linuxapp-gcc/examples/dpdk-l3fwd-power  -l 1-2 -n 1 --
-p 0x1 -P --config="(0,0,2)" -u

[--max-pkt-len PKTLEN]
  -p PORTMASK: hexadecimal bitmask of ports to configure
  -P: enable promiscuous mode
  -u: set min/max frequency for uncore to minimum value
  -U: set min/max frequency for uncore to maximum value
  -i (frequency index): set min/max frequency for uncore to specified frequency
index
  --config (port,queue,lcore): rx queues configuration
  --eth-link-speed: force link speed
  --cpu-resume-latency LATENCY: set CPU resume latency to control C-state
selection, 0 : just allow to enter C0-state
  --high-perf-cores CORELIST: list of high performance cores
  --perf-config: similar as config, cores specified as indices for bins
containing high or regular performance cores
  --no-numa: optional, disable numa awareness
  --max-pkt-len PKTLEN: maximum packet length in decimal (64-9600)
  --parse-ptype: parse packet type by software
  --legacy: use legacy interrupt-based scaling
 --telemetry: enable telemetry mode, to update empty polls, full polls, and
core busyness to telemetry
 --interrupt-only: enable interrupt-only mode
 --pmd-mgmt MODE: enable PMD power management mode. Currently supported modes:
baseline, monitor, pause, scale
  --max-empty-polls MAX_EMPTY_POLLS: number of empty polls to wait before
entering sleep state
  --pause-duration DURATION: set the duration, in microseconds, of the pause
callback
  --scale-freq-min FREQ_MIN: set minimum frequency for scaling mode for all
application lcores (FREQ_MIN must be in kHz, in increments of 100MHz)
  --scale-freq-max FREQ_MAX: set maximum frequency for scaling mode for all
application lcores (FREQ_MAX must be in kHz, in increments of 100MHz)
EAL: Error - exiting with code: 1
Invalid L3FWD parameters


Expected Result:
Startup successful
