Re: AMDGPU(4) - Question about man page

2020-10-22 Thread flint pyrite 
Below are various xorg.conf configurations. The only configuration
that errors is when using section "Device." If I do not have an
xorg.conf file or use section "OutputClass" X works fine. I hope this
clarifies my initial question?

xorg.conf:

Section "Device"
   Identifier "AMDgpu"
   Driver "amdgpu"
   Option "DRI" "3"
   Option "TearFree" "true"
EndSection

The man page is for the xorg driver.

That is to permit non-kms drivers, why are you setting this?

I suspect you have hardware claimed by radeondrm and not amdgpu.
It is hard to know without seeing a dmesg and /var/log/Xorg.0.log

AMDGPU(4) - Question about man page

2020-10-21 Thread flint pyrite 
Question: is the amdgpu(4) manual page up to correct and up to date?

https://man.openbsd.org/amdgpu

I set up an xorg.conf file in /etc/X11/xorg.conf and was trying to get
AMDgpu working.

The man page uses "Device" as the section. This worked as root but not
a normal user. When I changed "Device" to "OutputClass," X loaded
without error as a normal user.

Also, the man page does not mention setting

machdep.allowaperture=1

in /etc/sysctl.conf

cat /etc/X11/xorg.conf

Section "OutputClass"
Identifier "AMDgpu"
MatchDriver "amdgpu"
Driver "amdgpu"
Option "DRI" "3"
Option "TearFree" "true"
EndSection
#copied from /usr/X11R6/share/X11/xorg.conf.d/10-amdgpu.conf


#Section "Device"
#   Identifier "AMDgpu"
#   Driver "amdgpu"
#   Option "DRI" "3"
#   Option "TearFree" "true"
#EndSection

Section  "Files"
FontPath "/usr/local/share/fonts/spleen/"
FontPath "/usr/local/share/fonts/ghostscript"
EndSection

6.8 GENERIC.MP#98 amd64

As a normal user, and using "Device" X fails with "No devices
detected. If I leave out the section completely, X goes through mode
setting and chooses Radeon.
