            Bug ID: 1311
           Summary: [dpdk-23.11]
                    vhost_virtio_user_interrupt_with_power_monitor: Launch
                    dpdk-l3fwd-power core dumped on SPR
           Product: DPDK
           Version: 23.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: vhost/virtio
          Assignee: dev at dpdk.org
          Reporter: linglix.chen at intel.com
  Target Milestone: ---

[Environment]
DPDK version: dpdk 23.11-rc1: 5f9426b061
OS: Ubuntu 22.04.3 LTS/5.15.0-84-generic
Compiler: gcc version 11.4.0
Hardware platform: SPR(Intel(R) Xeon(R) Platinum 8490H)
NIC hardware: Ethernet Controller E810-C for QSFP 1592
NIC firmware: 4.40 0x8001c2f1 1.3492.0
NIC kdriver: ice-1.13.0_rc99_4_gb8ad35697

[Test Setup]
Steps to reproduce
1. ssh root at dpdk-yingya-spr2  

2.bind NIC port to vfio-pci,  
./usertools/dpdk-devbind.py -b vfio-pci 45:00.0

3. Launch vhost by below command:: 
./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 1-2 -n 4 --file-prefix=vhost
--vdev 'net_vhost0,iface=./vhost-net,queues=1' -- -i --rxq=1 --txq=1

4. Launch virtio with l3fwd-power::      
 ./x86_64-native-linuxapp-gcc/examples/dpdk-l3fwd-power -l 3-4 -n 4 --no-pci
--file-prefix=l3fwd-power --vdev=virtio_user0,path=./vhost-net
--log-level='user1,7' -- -p 1 --config="(0,0,4)" --parse-ptype
--pmd-mgmt=monitor

    eal/x86: use intrinsics for power management


    Inline assembly is not supported for MSVC x64 instead use _umonitor,
    _umwait and _tpause intrinsics.

test on SPR only
The bad commit 60943c04f3 will build failed, fixed commit ac1d4db91e (eal/x86:
fix build on systems with WAITPKG)
