📄 Description

Apparently hashcat needs access to this device for hardware acceleration
on AMD gpus and private-dev currently breaks that (see #6364).

It seems to be used by the "amdgpu" and "amdkfd" Linux kernel drivers
and as with /dev/dri/renderD128, this file is owned by the "render"
group.

Relevant udev rules from /usr/lib/udev/rules.d/50-udev-default.rules:

SUBSYSTEM=="drm", KERNEL=="renderD*", GROUP="render", MODE="0666"
SUBSYSTEM=="kfd", GROUP="render", MODE="0666"
SUBSYSTEM=="accel", GROUP="render", MODE="0666"

Environment: udev 255.6-1 on Artix Linux.
