## Minutes:

* [KyöstiM] Make build statistics downloadable from qa.coreboot.org
Work to create such tar-file with timestamps and ccache stats started here:
[https://review.coreboot.org/c/coreboot/+/75803](https://review.coreboot.org/c/coreboot/+/75803)
    * Martin will look at making the stats downloadable


* [KyöstiM] Is ccache for clang intentionally disabled for
coreboot-gerrit queue?
I think it would be possible to configure ccache for separate gcc and
clang backing storages.
    * Ccache was causing the build to take longer, so was disabled.
Martin did look at separating the two ccache locations, but the GCC
ccache is stored in ram, and there isn't typically enough memory to
save both.
    * Look at separating GCC and clang builds into two separate builds.
    * Look at coverity builds - should probably only build GCC.


* [coolstar] Pixel 2013 (Link) I2C bus ACPI (Windows vs Linux)
    * Attaches to IGD device because the i2c touchpad/touch screen are on it
    * Brand new drivers that are about to be submitted to MS to get
signed – hardware pre-dates I2CSerialBus (which normally would be in
HSW+), but new drivers on Windows use it.
        * It sounds like the best plan is to just push the patches and
see if there are any other suggestions.


* [Mailing list] Variants
    * There was a request on the mailing list to look at making a
company’s board a variant of the CRB. We should give recommendations
in the documentation about when variants should be used.
        * [Martin] vendors shouldn’t be under other vendors.  CRBs
shouldn’t be used as baseboards for other boards.
        * [Werner] Agree with Martin that variants should be used for
whitelabel devices, but not for CRBs.
        * [Ron] Things are the way they are because early in the
coreboot project, the other method of having vendors under CRBs was
tried.  The current method gives free reign to vendors to change
whatever they want.Vendors like to tweak their own boards and do not
like having other vendors introduce conflicting changes.
    * What about duplicated code and having to refactor functions out?
        * Ron - Sure, things can be refactored out, but deduping the
code can be very tricky - it leads to a lot of #ifdefs and gets very
messy. Mucking about in mainboard code may look good from an abstract
firmware engineering standpoint, but leads to issues.
        * Daniel: Using CRBs for baseboards could work as a tree with
another level, but agrees with Ron that having separate boards
probably makes more sense.
    * Who should handle any refactoring?
        * Martin thinks that pushing refactoring to new coreboot
engineers is going to make people want to not contribute to coreboot.
        * David - Definitely - can’t ask new people to rewrite as a
vendor without giving any direction as to why or how, or point at a
concrete example.
        * Ron - Agrees with David - pushing people too hard encourages forks.
        * Werner - could be a path to more contribution - submit
initial patch, then look at rewriting.
        * David - teaching good code quality and coreboot standards is
one thing, but pushing them without direction just leads to
frustration from the new person.
        * Daniel - Experience shows that refactoring without
understanding leads to poor refactors.  We could use some
documentation.  Any comments could be written as documentation to help
people.
        * David: “There are plenty of variants in the tree - look at
them for examples.” is not helpful - people would have no idea which
variant to look at. Especially when one doesn't exist.
        * Ron - stakes are much higher in firmware. It's easy to mess
up and brick a bunch of systems.
        * Martin & David: Refactoring by beginners causes those
beginners to rewrite the code in the CRB, which will lead to issues,
especially if they can’t test it.
        * Stefan - Making code look nice is problematic and can break things.
    * David will write up some documentation on what was discussed
here about when to use variants.  Daniel & Werner can help.


* Would it be interesting to have “shepherds” to help newcomers to the
community?
    * FelixS: I’m doing this for the releases.
        * How time consuming is this?
            * The process is started 6 weeks before the release. It
really varies, but typically a few hours a week.
    * Would people be interested in signing up to shepherd newcomers?
        * Matt, stefan, martin - sure
        * Martin will create a signup sheet
            * Ron, Jonathan, and Jpmurphy would be interested in
shadowing until they feel confident.
        * Martin to send email to the mailing list with a request for
additional shepherds.
    * Make script to help direct attention to patches (status:open and
+1'd or +2'd, maybe other criteria) to help get them merged - send to
mailing list periodically (weekly digest?).


* [DanielM] relaying from Slack
    * Warner Losh:  So I’m trying to understand something about a code
change request I got for FreeBSD. A long time ago (2015), we
committed: 
[https://cgit.freebsd.org/src/commit/?id=6c176113bbdd5](https://cgit.freebsd.org/src/commit/?id=6c176113bbdd5)
to implement quirks for what’s not about 10-year-old chromebooks, but
specified just the Acer Peppy.  Later (2016), I expanded this to all
coreboot instances since at the time I only knew that they were in
chromebooks. Lately, we’re getting a lot of requests to add exception
to the rules that are there. Starting in 2020, we started getting
these. I’m wondering if there’s a better way and if people here even
know what the issue is/was. DFBSD seems to have deleted all their code
for this.

and 
[https://github.com/DragonFlyBSD/DragonFlyBSD/commit/7f3d8d5546c701eceefe4437a49ffa6f01c7aa09](https://github.com/DragonFlyBSD/DragonFlyBSD/commit/7f3d8d5546c701eceefe4437a49ffa6f01c7aa09)
were the original dfbsd commits describing the problem with the
emulated i8042.
* Could someone reach out to Warner on slack?
* Matt and coolstar fixed this in the EC codebase in Matt’s repo.


# Notice
Decisions shown here are not necessarily final, and are based
on the current information available. If there are questions or comments
about decisions made, or additional information to present, please put
it on the leadership meeting agenda and show up if possible to discuss
it.

Of course items may also be discussed on the mailing list, but as it's
difficult to interpret tone over email, controversial topics frequently
do not have good progress in those discussions.  For particularly
difficult issues, it may be best to try to schedule another meeting.
