Bug 920752 – media-libs/mesa: add a use flag to disable swrast

• Status: UNCONFIRMED
• Product: Gentoo Linux

[Description om3i 2023-12-27 02:21:40 UTC]

Almost no one uses it, but it unconditionally increases build time and disk usage.

Reproducible: Always

[Comment 1 Matt Turner 2023-12-27 04:39:52 UTC]

Can you quantify any of that?

[Comment 2 om3i 2023-12-27 07:12:05 UTC]

All major pc gpu vendors have drivers available.
To see if the hardware driver is being used instead of swrast, rename
/usr/lib*/dri/*swrast_dri.so
before starting display server, or examine the results of
grep _dri /proc/'pidof Xorg'/maps.

I'm planning to add this with mesa-24.

    media-libs/mesa: Revert "Add VIDEO_CARDS=swrast"
    
    This reverts commit 46b2f0ab301a02e8763e461140b317e6dcd707bc.
    
    Users of the proprietary NVIDIA driver will likely have media-libs/mesa
    installed with no VIDEO_CARDS set, and without a driver present the
    configuration step fails.
