Kernel moving to Linux v5.14

Kernel moving to Linux v5.14

[Joel Stanley]

The openbmc kernel will move to a 5.14 based tree for Aspeed and
Nuvoton machines.

    linux-openbmc: Move to Linux v5.14

    This moves the OpeNBMC kernel to a v5.14 base. There are 78 patches in
    the tree, plus a the MCTP core and device tree changes that were merged
    in v5.15 which have been backported.

https://gerrit.openbmc-project.xyz/c/openbmc/openbmc/+/46847

Welcome to the party to the MCTP core, the first new subsystem to be
added to mainline for the bmc since we added FSI support in 2017.

While the v5.14 tree is not LTS like the v5.10 kernel was, it is
necessary to keep pushing forward the version to ensure upstream
development integrated back into the openbmc tree.

Cheers,

Joel

This has now been merged. Thank you to those who reviewed the change.

Please address future kernel changes to the dev-5.14 tree.

Cheers,

Joel

Thanks Joel for carrying and backporting the patches. I'm also porting
Linux v5.14 to Facebook OpenBMC tree and these patches are very helpful.


Cheers,

Thanks, I appreciate you saying so.

Even more helpful would be to have your patches in the openbmc tree, I
would think.

Would you consider doing that, instead of us both having to spend time
maintaining separate trees?

Cheers,

Joel

Hi Joel,

I'd love to share the same kernel tree, but I'm afraid it will introduce
a lot of overhead for you at this stage, because we still have a set of
local patches which may take a while to upstream (mainly due to resource
constraints).

In other word, sharing the same kernel tree is my goal, but we are not
fully ready yet (couldn't meet three iterations policy) :)


Cheers,

Tao
