Subject: Re: [PATCH v5 1/2] power: introduce PM QoS API on CPU wide
Date: Wed, 3 Jul 2024 01:32:39 +0000 [thread overview]
Message-ID: <702fd523-cb50-22cb-190d-c649e5442309@loongson.cn> (raw)

Hi Huisong,
I knew that this patchset was based on the *dpdk-next-net* repository in
our previous communication. However, maybe it's better to rebase this
pactchset on the *dpdk* repository. Because the CI system is not smart
enough to recognize the patchset as a change for the *dpdk-next-net*
repository. I personally feel this patchset is more likely a change for
the *dpdk* repository because it modified the `lib` directory which is
the infrastructure of DPDK instead of a feature for *dpdk-next-net*.
Best regard,
Min Zhou
