No DRI3 support detected

Postby vkxt » Wed Feb 09, 2022 4:46 pm

When running the vkcube demo on a raspberry-pi 4, I get an error:

$this->bbcode_second_pass_code('', '
Selected GPU 0: V3D 4.2, type: 1
vulkan: No DRI3 support detected - required for presentation
Note: you can probably enable DRI3 in your Xorg config
Could not find both graphics and present queues
')

I have vulkan-broadcom, vulkan-mesa-layers, vulkan-validation-layers, vulkan-extra-layers, vulkan-headers, and vulkan-icd-loader installed.

OpenGl works fine and runs glxgears without problems using mesa.

I suspect I need to install the DRI3 xorg extension (xdpyinfo -queryExtensions did not show it) for this to work but I cannot find a package that contains it.

Also, there's this forum post of a raspberry pi 4 with DRI3 extension enabled so I think I'm missing something: https://archlinuxarm.org/forum/viewtopic.php?f=9&t=14516&p=63785&hilit=dri3#p63785

Any ideas how to install/enable DRI3?
Any help is appreciated.

edit:

The device section explicitly states DRI3 and the Xorg log specifies that my device is explicitly being used but then modesetting claims that the DRI option is not used at all and then swaps to DRI2.

/etc/X11/xorg.conf:
$this->bbcode_second_pass_code('', '
Section "Device"
Identifier "Broadcom Graphics"
Driver "modesetting"
Option "DRI" "3"
EndSection
')

/var/log/Xorg.0.log:
$this->bbcode_second_pass_code('', '
...
[ 414.290] (==) No device specified for screen "Default Screen Section".
