This last paste looks remarkably similar to an issue currently seen on
the Radxa ROCK Pi 4B (RK3399) during power-up after a soft reboot
(`sudo reboot`) is issued. We're presently running v5.15.35 [0].
It's not clear how this issue (present 3 years ago) was finally
resolved. From the thread, it looks as if the fix might have made its
way into ATF, but I'm 87.6% sure ATF is not running on this platform
(yet).
Note that the u-boot we're using is also quite old:
U-Boot 2019.10-09248-g8511c75bb4 (Jan 08 2020 - 17:13:03 -0800)
... so this could easily be the root cause. The current plan is to
try to update this ASAP. However early attempts are yet to result in
a successful boot.
I see that Brian recently added a few patches related to PD/DVFS, but
again, these appear to be ATF related.
Would anyone be able to shed some light onto this for me please?
As always, any help would be gratefully received.
Kind regards,
Lee

Good Evening,
That's definitely not stock v5.15.35, it's been tagged as an android kernel.
5.15.35-android13-5-00092-g525d77310a20

The rk3399 SoC has a hardware bug where the power domains are not
reset upon a soft reset. This leads to situations like this one where
power domains are shut down during shutdown but aren't restored on
reboot. Mainline TF-A was patched to force all power domains online
when a soft reboot is triggered, which solved that issue. What
particular issues are you having initializing modern u-boot on this
device? Is there a particular reason it isn't using Mainline TF-A?
I've also run into issues on rk356x where the regulator powering a
power domain isn't powered due to a soft reset, which also causes
faults like this. Set your main regulators to always-on and see if it
helps with the issue.
Very Respectfully,
Peter Geis

Hi, Peter,
Thank you so much for your reply.

It's not stock, no.
Although the differences from RockPi's perspective are minimal.
The main difference is the way the kernel is configured.
It's GKI:
https://android.googlesource.com/kernel/common/+/refs/heads/android13-5.15/arch/arm64/configs/gki_defconfig
Plus a few non-GKI specifics:

This is the output: https://pastebin.ubuntu.com/p/d5DmsSBnrR/
Speaking with one of the guys who supports RockPi 4 in AOSP, he
suspects the DDR settings. Apparently settings for older SoCs
sometimes get clobbered when support for newer SoCs is added.
I am yet to investigate the u-boot story in any detail.
It's on my TODO list for today.

We're not using Trusted Firmware yet.
Although I'm starting to think this should be re-prioritised.

I'll do that. Thanks for the tip.
Our main issue currently is an RCU-lock-up, again on soft reboot:
[ 21.226951][ C0] rcu: INFO: rcu_preempt detected stalls on CPUs/tasks:
[ 21.227637][ C0] rcu: 5-...!: (1 GPs behind) idle=3de/1/0x4000000000000000 softirq=9/10 fqs=3 last_accelerate: 0000/efb9 dyntick_enabled: 0
[ 21.228890][ C0] (detected by 0, t=5252 jiffies, g=-1167, q=46)
Do you think these issues could all be related?
Thanks ever so much for your reply Peter.
You've potentially saved us hours and hours of debugging.
Kind regards,
Lee

As far as I know it's being worked on by others, I have some ideas for
this as well but I've been focused on rk356x lately.

The rk3399 TPL code is specific to the rk3399 and it really hasn't
been touched much recently. I'm using the latest Mainline U-Boot on
both my Rockpro64 and Pinephone-Pro. I don't see TF-A being loaded,
which should happen between:
Trying to boot from BOOTROM
Returning to boot ROM...
Otherwise it just looks like the TPL code doesn't like being in a
single channel configuration. Does the 2GB model just forgo the second
ram chip? Or is this actually a 4GB model and it isn't detecting the
second chip in both downstream and mainline? Could you include the
TPL/SPL portion of downstream's output?

This platform does not work at all without TF-A. Optee is optional.
Either you are using the downstream blob from Rockchip or Mainline
built yourself. Personally I prefer using Mainline everything. If you
build Mainline U-Boot without TF-A it will throw a warning at the end
that says the created binary is non-functional.

If you've powered down a minor power domain while a driver was still
active, sure.

TPL/SPL are mostly silent on the downstream build:
https://pastebin.ubuntu.com/p/m2bBdjF8Wq/
Not sure if it helps at all, but ArmBian is pretty noisy:

Right. Played a lot with this today.
Our build was using TF-A which was built-in to the primary loader.
I had 2 interesting results today. No idea how to explain them.
First one was with Mainline u-boot and Mainline TF-A, which found, but
was seemingly unable to boot the kernel:
https://pastebin.ubuntu.com/p/9HRhPyfjYK/
The second interesting result I had was using our downstream u-boot
with Mainline TF-A. It booted perfectly from cold, but managed to get
stuck in the TPL on soft reboot in a very similar way to the one I
reported earlier when not booting with TF-A ("Channel 1: col error"):
https://pastebin.ubuntu.com/p/hwmBzxDBgc/
Thanks again for your insight.
Kind regards,
Lee

Weird that downstream and mainline are being built with none of the
debug stuff enabled. Armbian clearly shows the initial setup occuring
correctly, and that it's a 4GB board. It's using both the Rockchip
miniloader with a Rockchip TF-A blob as well.

Mainline TF-A defaults to 115200 for its uart messages, so you need to
either A. pass the uart config from U-Boot to TF-A with a platform
config option (unreliable in my experience), B. change U-Boot to
115200, or C. change TF-A to 1.5M (the path I take). Your mainline
hang is exactly where you expect to hang with a non-functional TF-A. I
enable some additional prints in my U-Boot tree to know exactly what
gets loaded during SPL. There are also debug prints you can enable in
TPL to get the setup results.
Would you be willing to run make savedefconfig from your mainline
setup and share the result?

Looks as though savedefconfig aren't u-boot or TF-A commands, so I'm
guessing you mean kernel:

make savedefconfig causes the make system to output a defconfig file
in your current tree directory. It's a part of the kernel make system,
which also works in U-Boot mainline since it utilizes the same system.
It's how the configs in configs/ are generated. I can use that
simplified config to examine your current setup.
Or if you want to just host a git repository of your current U-Boot
mainline tree with an intact .config, that works as well.

Yes, I know what savedefconfig does. :)

I'm afraid it's not as easy as that. The build system I'm using is
wrapped up in Android build-system-ness. I'll have a look to see if I
can roll a defconfig by hand some how.

Okay, so it's the u-boot defconfig you're after.
And Mainline, right, not our Android one?

That's interesting. Would this change result in me now being able to
see the console output from this (apparently) failed attempt:
https://pastebin.ubuntu.com/p/9HRhPyfjYK/
However the result is the same as the downstream kernel where it
fails in the TPL on soft reboot:
https://pastebin.ubuntu.com/p/TZBYqTMCnN/
No TF-A messages seen though still.
Is it possible that u-boot only runs TF-A on cold boot? Seems odd.
What was the extra logging you mentioned before?

I'm convinced that TF-A is not functional on your mainline config. No,
TF-A will execute on any reset that triggers SPL, as SPL loads TF-A
and jumps to it as part of the FIT load.

This is what my rockpro64 looks like with TF-A executing. Note I've
enabled a bit of extra TF-A debugging, normally it just prints out the
TF-A version number. TF-A reports itself as BL31.

I'm currently pulling the rk3399-rock-pi-4b.dts that's in mainline
linux to build a quick image for you, if you're interested.
