Bug ID: 14416
Summary: Mesa3D missing DRI3 support for various Gallium
drivers
Product: buildroot
Version: 2021.08.2
Hardware: Other
OS: Linux
Status: NEW
Severity: major
Priority: P5
Component: Other
Assignee: unassigned@buildroot.uclibc.org
Reporter: info@arachnodroid.de
CC: buildroot@uclibc.org
Target Milestone: ---
Hi!
I've found https://bugs.busybox.net/show_bug.cgi?id=13831 and can confirm that
Mesa3D is not working on my Raspberry Pi 4. It turns out, that the logic in
mesa3d.mk seems to be broken, as it doesn't enable DRI3 support, though it's
required for V3D/VC4. Otherwise glxgears doesn't work and complains with a
Failed to open bo 1: Permission denied.
Below you will find a patch to enable DRI3 support if one of the Gallium
drivers is selected which requires DRI3 support.
Best regards,
Michael
