            Bug ID: 1497
           Summary: [dpdk-24.07] [ABI][meson test]
                    driver-tests/event_dma_adapter_autotest test hang when
                    do ABI testing
           Product: DPDK
           Version: 24.07
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: eventdev
          Assignee: dev@dpdk.org
          Reporter: yux.jiang@intel.com
  Target Milestone: ---

[Environment]

DPDK version: 24.07.0-rc2
DPDK ABI version: 23.11.0
OS: RHEL9.0/5.14.0-70.13.1.el9_0.x86_64
Compiler: gcc version 11.2.1 20220127 (Red Hat 11.2.1-9)
Hardware platform: Intel(R) Xeon(R) Platinum 8180 CPU @ 2.50GHz


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

1, Build latest main dpdk24.03-rc1
rm -rf x86_64-native-linuxapp-gcc
CC=gcc meson -Denable_kmods=True -Dlibdir=lib  --default-library=shared
x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc
rm -rf /root/tmp/dpdk_share_lib /root/shared_lib_dpdk
DESTDIR=/root/tmp/dpdk_share_lib ninja -C x86_64-native-linuxapp-gcc -j 110
install
mv /root/tmp/dpdk_share_lib/usr/local/lib /root/shared_lib_dpdk
ll /root/shared_lib_dpdk
cat /root/.bashrc | grep LD_LIBRARY_PATH
sed -i 's#export LD_LIBRARY_PATH=.*#export
LD_LIBRARY_PATH=/root/shared_lib_dpdk#g' /root/.bashrc

2, Build LTS dpdk23.11.0
rm /root/dpdk
tar zxvf dpdk_abi.tar.gz -C ~
cd ~/dpdk/
rm -rf x86_64-native-linuxapp-gcc
CC=gcc meson -Denable_kmods=True -Dlibdir=lib  --default-library=shared
x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc
rm -rf x86_64-native-linuxapp-gcc/lib
rm -rf x86_64-native-linuxapp-gcc/drivers

3, Launch dpdk-test and run event_dma_adapter_autotest
MALLOC_PERTURB_=132 DPDK_TEST=event_dma_adapter_autotest
/root/dpdk/x86_64-native-linuxapp-gcc/app/dpdk-test -c 0xff -d
/root/shared_lib_dpdk --vdev=dma_skeleton


Show the output from the previous commands.

    eventdev/dma: reorganize event DMA ops

    Re-organize event DMA ops structure to allow holding
    source and destination pointers without the need for
    additional memory, the mempool allocating memory for
    rte_event_dma_adapter_ops can size the structure to
    accommodate all the needed source and destination
    pointers.

    Add multiple words for holding user metadata, adapter
    implementation specific metadata and event metadata.

-----------Note---------
Based on dpdk24.07-rc2 which includes
https://bugs.dpdk.org/show_bug.cgi?id=1469's fix patch, also test hang.

Please confirm it need fix or not on ABI compatibility testing or it needn't
test for ABI compatibility testing. Thanks.
