[dpdk-ci] Fedora Rawhide Error on Compile DPDK with GCC11

Hello everyone,

We have successfully added GCC11 to Fedora Rawhide, but when we are trying
to compile DPDK with GCC11. The compilation failed on an error showed below:

../app/test/test_graph_perf.c
../app/test/test_graph_perf.c: In function ‘graph_init’:
../app/test/test_graph_perf.c:311:1: error: wrong number of arguments
specified for ‘access’ attribute
  311 | {
      | ^
../app/test/test_graph_perf.c:311:1: note: expected between 1 and 3, found 4
[2368/2483] Compiling C object
drivers/libtmp_rte_pmd_octeontx2_event.a.p/event_octeontx2_otx2_worker_dual.c.o
ninja: build stopped: subcommand failed.

Here is the link to the Bugzilla ticket for this issue:
https://bugs.dpdk.org/show_bug.cgi?id=557#c0

Thanks,
David

Thanks for reporting David.
I assigned the bz to Jerin, as this is graph unit test code.

Fyi, we had a couple of gcc 11 fixes from Ferruh and others, but all
of them did not reach the main tree yet.

We will look into this

Could you share those patches though dome form, So that we can just focus on Graph issue only.

Correction, next-net has been merged since then, and issues reported
by Ferruh have patches in main.

I was referring to Ferruh series:
https://patchwork.dpdk.org/project/dpdk/list/?series=12380&state=*

Commits in main:
https://git.dpdk.org/dpdk/commit/?id=62aa0e8c66
