OpenBMC Linux 6.6

OpenBMC Linux 6.6

[Joel Stanley]

Hot on the heels of the last bump, here is the latest kernel base for
the aspeed machines.

  https://gerrit.openbmc.org/c/openbmc/openbmc/+/67772

If you're able to test, please comment on gerrit and give the change a +1.

There was a config regression due to CONFIG_EMBEDDED going away, which
is fixed separately here:

  https://gerrit.openbmc.org/c/openbmc/openbmc/+/68117

Commit message for the bump follows:

There are 56 patches in the tree, with 36 of those patches not
yet queued for merging in v6.7.

v6.6 is an LTS kernel as decreed by the kernel.org maintainers. The
OpenBMC kernel maintainers encourage everyone to ship the latest kernel
as it has the most code review and upstream code.

If you can send SHAs for the upstream commits, we can cherry pick them.

If they're not upstream, but someone is actively working on them, then
please post the lore links and we can look at them.

Cheers,

Joel

Re: OpenBMC Linux 6.6

[Tomer Maimon]

Will send SHAs of upstream drivers in kernel 6.7

Thanks,

Tomer

Nice! The npcm8xxx has been making good progress I see.

All of these are merged into the dev-6.6 tree.

Re: OpenBMC Linux 6.6

[Quan Nguyen]

Hi Joel,

We do have some pending patches for upstream, but unfortunately, they 
have not been merged yet. By the way, I'd like to list them here and 
hope to get more comments.

1. 
https://lore.kernel.org/all/20231130072849.3075741-1-quan@os.amperecomputing.com/
There is no feature change on this patch, just a minor change so that, 
in the case of the bmc ssif message abortion, the annoying printout is 
limited.

2. 
https://lore.kernel.org/all/20231208033142.1673232-3-quan@os.amperecomputing.com/
This series is to fix some issues found on the i2c-aspeed driver. This 
version is new and was posted just after I'm confident with the test 
results on ast2500 and ast2600.
My special thanks to Andrew, whose comment made the code look much 
better than my original version.

3. 
https://lore.kernel.org/all/20231130075247.3078931-1-quan@os.amperecomputing.com/
We do see significant improvement with this patch, which is just to 
simply requeue the mctp packet if, somehow, the i2c core returns with 
-EAGAIN (arbitration lost). Jeremy has not agreed yet, but I'd like to 
list it here to see more comments.

Thanks a lot in advance.
- Quan

What is the tentative timeline for merging this?  I'd like to try it out
on a few of our platforms but it'll probably be Friday before I get
around to that.

Once we get a few +1s, in the absence of -1s, it can go in. I can hold
off if you want to test your platforms.

However, we don't need to hold up for too long. If people find bugs
then we can always add fixes on top.

Re: OpenBMC Linux 6.6

[Tao Ren]

Hi Joel,

Finally I got chance to sanity test Linux 6.6 on my AST2600 BMC, and
everything looks good so far.

I'm also planning to move all the Meta Network AST2400 and AST2500 BMC
platforms to Linux 6.6, but I need to upgrade yocto at first (we are
still running dunfell, which doesn't seem to be compatible with 6.6).
Anyways, I will update back if I found problems.

Again, thank you for maintaining the OpenBMC kernel tree!


Cheers,

Tao
