<milkylainen> TF-A blackbelt? stm32mp157f dk2. I can get a vanilla kernel (5.18/5.19) to start from BL33 U-Boot from vanilla TF-A 2.7 but not using stm TF-A v2.6. Kernel decompression happens. Then nothing.
<milkylainen> I dunno if U-boot is to blame or not? (probably not actually)

persmule has quit [Ping timeout: 268 seconds]
<hramrach> on rockchip power domain management is apparently offloaded to ATF
<hramrach> milkylainen: do you have early console enabled?
<hramrach> and if clock state is suspect you can add some code in u-boot that dumps the clock sstate before starting the kernel so you can tell if there is actually a difference

<rfs613> running "patman send -n", and it says:
<rfs613> Send a total of 9 patches with no cover letter.
<rfs613> why no cover letter? I've got Cover-letter: ... END in one of my commits, and it has picked up Series-Prefix etc from the same commit
<milkylainen> marex, hramrach: I do have console enabled.
<milkylainen> hramrach: I think tf-a/sp_min is still alive. I get console printouts from it even though the kernel seems dead?
<milkylainen> And yes, clock shenanigan printouts.
<rfs613> ok, got my cover letter... however it has a couple of extra blank lines that I can't account for.

<hramrach> milkylainen: early console in the linux kernel - if it crashes very early you might get some output
hanetzer has joined #u-boot
<hramrach> and it's better to figure out how to enable it on the working setup

vagrantc has joined #u-boot
<milkylainen> hramrach: I think I've enabled just about everything. Earlyconsole through stm32 uart at a specific physical offset.

<milkylainen> Should be ok.
<cambrian_invader> the commit message says "On platforms that have not migrated to enabling CONFIG_DM_ETH already, disable CONFIG_FMAN_ENET"
<cambrian_invader> but e.g. configs/ls1046ardb_sdcard_defconfig has DM_ETH enabled, as done by 045ecf89925 ("configs: enable DM_ETH support for LS1046ARDB")
<Tartarus> Hmm
<Tartarus> There was _some_ level of "board blew up when forced to DM_ETH"
<Tartarus> So...
<cambrian_invader> fwiw I am currently using that board and I have DM_ETH enabled
<Tartarus> cambrian_invader: OK, thanks for the feedback, I'll try re-working things a bit with the remove the corenet_ds platforms, as it's those, and the arm layerscape platforms in that commit
<Tartarus> Maybe something else went awry
<Tartarus> sjg1: Bad memory / disk in that new builder? https://source.denx.de/u-boot/u-boot/-/jobs/480338 and the whole branch was fine before I merged, and fine locally
<marex> hramrach: and yet, robher is such a nice person
<marex> hramrach: just run the DT bindings check , reply to feedback , and yo should be fine
<marex> (assuming you don't get involved in contentious patches like critical clock or DPI pixel format or ... )
<marex> hramrach: no stress
<cambrian_invader> IME I stop getting replies after the second or third email
<marex> milkylainen: ATF is technically more like a library, you call (jump) at it, it does magic, and returns back
<cambrian_invader> which means I have to push out another series to get any more feedback
<marex> milkylainen: there is no scheduler involved per-se
<marex> cambrian_invader: that's wrt DT bindings ?
<cambrian_invader> yea
<marex> cambrian_invader: clearly you're not involved in the right kind of contentious fla^Wdiscussions :)
<cambrian_invader> >.>
<cambrian_invader> the other problem is that subsystem maintainers don't see bindings as anything they have to comment on
<marex> cambrian_invader: like, how do you define DT bindings for DPI bus and how to match them between DPI source and sink, and how to handle things like scan direction etc :)
<marex> cambrian_invader: I think we will soon arrive at trying to future-proof the bindings to handle even temporal resolution of the panel, in case there is ever a panel with 4D support
<cambrian_invader> the only DPI I'm familiar with is "dots per inch"
<marex> display parallel interface, old RGB panel stuff
<cambrian_invader> fun
<marex> I know, right ?
<marex> cambrian_invader: I think there is now another person helping Rob with the DT binding reviews though, so the congestion might get better
<cambrian_invader> I have noticed that; but they have the same personality :)
<cambrian_invader> and of course, it's extra fun when rob reviews v1, and krysztof reviews v2
<marex> cambrian_invader: at least someone does review your patches in reasonably timely manner
<cambrian_invader> yes...
<marex> there are subsystems where I got one reply every 2-3 months , and that reply was totally off the mark, like the maintainer again forgot what we discussed
<marex> so ... I think DT is still really good
sbach has quit [Read error: Connection reset by peer]
<cambrian_invader> (I will never submit another PWM driver)
<marex> that bad ?
<Tartarus> cambrian_invader: Ah-ha! https://source.denx.de/u-boot/u-boot/-/jobs/480387 so ys, 1046ardb is fine, but so so many other 104xzzz platforms are not, so I ended up doing a git grep -Ovim ... I bet
<cambrian_invader> it took ~1 month to get feedback, and every time ukk would find something that he missed the last time
<marex> cambrian_invader: and yet you can just talk to uwe in #armlinux :)
<cambrian_invader> hm, maybe I should lurk there as well
sbach has joined #u-boot
<cambrian_invader> is it more active than #kernelnewbies?
<cambrian_invader> Tartarus: AFAICT the LS104[36]AQDS boards have disappeared from the internet
<cambrian_invader> the only place where I could find references was in U-Boot and Linux
<Tartarus> cambrian_invader: oh fun....
<Tartarus> cambrian_invader: And looking harder, OH, I did a sed -i -e '/CONFIG_FMAN/d' configs/ls1046a* rather than aqds*
<Tartarus> So, ah-ha, I'll v2, thanks
<marex> cambrian_invader: no, it's mostly dead unless discussion starts
