[Intel-gfx] [bug report] drm/i915: Computer does not shutdown,

[Mario Hüttel]

Hello,

It seems, like the mailing list, didn't accept my email. So I'll send
it again:

I want to report a bug. I have a PC with Intel i7-6700K processor (with
integrated graphics) and an AsRock Fatal1ty Z170 Gaming K6 mainboard. I
use the CPU's integrated graphics.
My system is Archlinux with Kernel v5.11.6.

Using this setup, my PC works normally. However, when I shut it down,
the power is not cut. Fans keep spinning and LEDs stay on. I couldn't
detect any other problem when shutting down. Drives etc. stop as
expected and the video is blank. Even after waiting several hours, the
system doesn't power down.

Restarts work normally.

I haven't yet found any other people on the internet that have the same
bug.

I used git bisect to find the commit that causes this behavior on my
machine. The result is: fe0f1e3bfdfeb53e18f1206aea4f40b9bd1f291c is the
first bad commit.

I hope this is the correct mailing list for this issue.

Let me know if you need more information or someone to test it.

Thanks

Mario

Thank you for doing a bisect that is always very helpful.

To save others the trouble of having to look up the hasj, that is:

"drm/i915: Shut down displays gracefully on reboot"

Which is the same commit as which I've reported is causing issues
with DSI panels not lighting up on reboots on some BYT/CHT devices.

Since this seems to mostly be intended to fix issues surrounding
DP MST stuff, maybe the graceful shutdown should only be done when
MST is in use?

Regards,

Hans

No. It also fixes Windows, lols.

Ok, can you at least take a look at my patch which fixes (works-around)
the issues for DSI panel on BYT/CHT DSI devices:

https://patchwork.freedesktop.org/patch/422481/

?

In that case the display stays black after reboot in the BIOS / in apps
using the EFI fb/console such as the grub menu and when using fastboot
it also stays black under Linux (I did not test Windows) only after forcing
a modeset under Linux the DSI LCD panel works again.

As I mention in the commit msg given the age of the platforms involved
I think that a simple workaround as I suggest there is best.

Regards,

Hans

Yes I'm seeing a lot of bounces from the linux.intel.com mailserver lately
(and only from that mail server and not from any other mailservers).

You should have also received a copy through the intel-gfx lists though.

Or you can grab a raw copy from patchwork.

Regardless of the mail-issue a review would be much appreciated.

Regards,

Hans


p.s.

While on the subjects of bouncing emails, did you see Jani's reply to:
https://patchwork.freedesktop.org/patch/422669/

Where he asks for a second opinion on that patch from you ?

Nope. Didn't come through the list either.

As in 'reboot' ?

That's a bit odd then. Hmm. What could be the difference between
shutdown and reboot?

Does the same thing happen with a working kernel if you try to
shut down the machine when all displays are blanked?

Hmm. Wonder if we can get logs from this with either netconsole
or serial or would those be shut down already...
