            Bug ID: 1445
           Summary: [dpdk-24.07] dpdk-test-dma-perf hang on Ubuntu24.04
           Product: DPDK
           Version: 24.07
          Hardware: All
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: other
          Assignee: [email protected]
          Reporter: [email protected]

Target Milestone: ---

[Environment]

DPDK version: 24.07.0-rc0
OS: Ubuntu 24.04 LTS (Noble Numbat); 6.8.0-31-generic
Compiler: gcc version 13.2.0
Hardware platform: Intel(R) Xeon(R) Platinum 8380 CPU @ 2.30GHz NIC hardware & NIC firmware:

    root@dut245:~/dpdk# ethtool -i ens801f0np0
    driver: ice
    version: 6.8.0-31-generic
    firmware-version: 4.30 0x80019938 1.3403.0

[Test Setup]
Steps to reproduce
List the steps to reproduce the issue.

1.Bind 2 CBDMA to vfio-pci driver:

./usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:00:04.0 0000:00:04.1

2.Create test_config.ini
/root/dpdk/test_default_config.ini

root@dut220:~/dpdk# cat /root/dpdk/test_default_config.ini
[case1]
type = DMA_MEM_COPY
mem_size = 10
buf_size = 64,8192,2,MUL
dma_ring_size = 1024
kick_batch = 32
src_numa_node = 0
dst_numa_node = 0
cache_flush = 0
test_seconds = 2
lcore_dma = lcore1@0000:00:04.0,lcore2@0000:00:04.1
eal_args = --in-memory --file-prefix=test

[case2]
type = CPU_MEM_COPY
mem_size = 10
buf_size = 64,8192,2,MUL
src_numa_node = 0
dst_numa_node = 0
cache_flush = 0
test_seconds = 2
lcore = 1,2
eal_args = --in-memory --no-pci

3, launch dma-perf testing x86_64-native-linuxapp-gcc/app/dpdk-test-dma-perf --config /root/dpdk/test_default_config.ini --result /root/dpdk/test_default_config.csv

root@dut220:~/dpdk# x86_64-native-linuxapp-gcc/app/dpdk-test-dma-perf  --config
/root/dpdk/test_default_config.ini

[Actual Result]
dpdk-test-dma-perf hang

[Expected Result]
Test OK

[Regression]
Is this issue a regression: (N)
The first time to test on Ubuntu 24.04.
Notes: test passed on Ubuntu22.04.3
