[gentoo-user] AMDGPU: computer won't shut down

[gentoo-user] AMDGPU: computer won't shut down

[n952162]

I posted about this problem perhaps a year ago - when running with
AMDGPU, my system won't turn off, I have to hold the power button down
for a long time, forcing it down.

At that time, various people commented. but AMDGPU didn't work at all
for me in the end, didn't talk to my HDMI display.

I gave up on it.

Thanks to all the great help here, I finally got my system properly
updated and AMDGPU working, and it  finally talks to my HDMI display. 
But, it still doesn't shut down.

Is it a bug?  Is my system still not right?  Is there something I have
to do yet?

I assume you are using the AMDGPU drivers [1], but are you also using AMDGPU-PRO
(closed-source accelerator) [2] ?  Also, are you loading the  firmware  directly
into the kernel, or as kernel modules ?

Which GPU series/firmware do you have installed [3] ?

AMDGPU yes

AMDGPU-PRO no.

The following assignment is on the linux line when booting in grub:

amdgpu.dc=1

When I make that 0, the system shuts down properly when the power button
is pressed.

When it's 1, the system hangs after blank screen  when that button is
pressed.

I found this in the AMDGPU webpage:

    /AMDGPU with Display Core was first implemented for VEGA10 (GCN5.0)
    and RAVEN (with DCN 1.0) GPUs/APUs. Kernels before version 4.17 have
    (experimental) DC support for older cards (GCN1.1 and newer) via
    command line option /amdgpu.dc=1/, which may work better than the
    older radeon kernel module. Likewise, if DC needs to be disabled for
    any particular reason, option /amdgpu.dc=0/can be used on the kernel
    command line.
    /

It's not clear to me if  DC serves a function in kernels >= 4.17 or why
it's installed as default by grub ...

I don't see anything similar in the new kernel parameters I posted to
this topic, but I do find this in my .config file:

#
# Display Engine Configuration
#
CONFIG_DRM_AMD_DC=y
CONFIG_DRM_AMD_DC_DCN1_0=y
# CONFIG_DEBUG_KERNEL_DC is not set

Was this left over from an earlier configuration and not properly
cleaned out, or is it necessary, for some reason?

Can someone explain how the amdgpu.dc=1 parameter gets passed to grub?

Thanks in advance.

Okay, I found out how amdgpu.dc=1 gets into grub - via
/etc/default/grub.  I'm not sure who put it there - was it the kernel
make process?

Note that even with amdgpu.dc=0, I still have (finally!) HDMI output to
my monitor.  There's a lot of talk on the internet about whether
amdgpu.dc=1 is good or bad, but nobody seems to know or explain what
it's about, or the role of Display Core WRT to AMDGPU.

The only important thing unresolved for me now is whether I still need
those DRM_AMD_DC kernel variables, above.

Is it in /etc/default/grub's GRUB_CMDLINE_LINUX_DEFAULT=?

If the question is how it got there, maybe the timestamp on the file offers
a hint?
