Dear Maxime, Bruce, David, Chenbo,
Could you please help review the code ? The goal is to merge the changes before
September 18 when the merge window closes for SPDK v25.09.
I will help review the code, but there are no guarantee it will be
merged in main branch before September 18th.
Can you elaborate about the tests you have run?
Have you ensured it is still working properly with Vhsot-user/Virtio-net?
Maxime

- add protocol feature support add and removal of memory
regions/slots dynamically.
- this patch set has been tested with multiple instances of fio
What is "fio"?
Fio is an open-source tool to test I/O workloads on disks and file systems.
connected via libblkio to spdk target backed unix domain socket.
- please apply this this patch-set to dpdk mainline as well as
version 25.03.0.
As mentionned previously, we don't plan to maintain 25.03.
I understand you need it for SPDK,
but I think SPDK should rely only on LTS branches.
Is there a specific reason why 25.03 is required in SPDK?
When we do sub-module init on spdk master, it uses dpdk version
25.03 from
it's own sub-repo.
Our changes for vhost have already been pushed to spdk master. We
have also pushed the same dpdk changes in the spdk sub-repo "dpdk"
which is version 25.03. I was just ensuring that there is uniformity
in the 25.03
codebase, whether it is on the spdk sub-repo or 25.03 within dpdk repo.
Ok, still, it would be better for SPDK to uses LTS as we have no plans
to add extra stable branches.
Also, your series may be considered as a feature and not a bug fix, so
even if
25.03 would be a stable branch (which it is not), it would not be
backported against it.
Understood. I would request that we merge my changes into DPDK mainline
before September 18 when the merge window closes for SPDK v25.09.
v2:
- fixed warnings with e-mail address
- fixed warnings with typos
- there is a warning about __rte_packed_begin not being in pair
with __rte_packed_end which on reading the code turns out to be
false. It is an anomaly of how git-format generates the patch and
how check-patch checks it.
When sending a v2, please use -v2 so it is reflected in the email subject.
I will remember this for next time. Thank you for pointing that out.
