>Description:
Hello,

I don't know many things about system programming for now, especially regarding gpu and OpenGL driver.

However I know for sure that as Iris improved Gen 8 (Broadwell) gpu drivers.
Crocus helped a lot on older drivers (I have a gen5 Ironlake mobile gpu supporting crocus)

For now I am using the installed 19 (and sometimes tries the pkgsrc version 21.3) and there are still problems (not sure it is not related to kernel driver though) but I was curious if the MesaLib maintainer tried to enable crocus. This could help with problems.

I know it is not enabled in the PKG src binary build because the MESA_LOADER_DRIVER_Override=crocus global env variable does not find the right crocus.so in any of /usr/X11R7/lib/modules/dri or /usr/pkg/lib/dri/ (for pkgsrc version.

Crocus was added in Mesa 21.2 or something like that and this could be a nice addition (It brings some better responsiveness) for older laptop hardware (and NetBSD is often better supporting old hardware AFAIK).

This report is just a suggestion.

I am currently trying to reproduce the Issue I faced recently on RC6 on my GPU to make another bug report.
(Coredump on glxgears with both Integrated and pkgsrc MesaLib). But it is not working so nicely and I understand why webgl is not enabled by default in firefox... (also had crash on some websites)

All the best,

Enable Crocus on MesaLib
