Description Jan Beich freebsd_committer freebsd_triage 2021-07-27 21:07:34 UTC 
After ports 22a85734ff71 OpenGL renderer in yuzu-qt5 stopped working because i965 is stuck with incomplete support for newer extensions. For example, in glxinfo output OpenGL 4.6 -> 3.0 and DRI (classic) give away i965.

Comment 1 Jan Beich freebsd_committer freebsd_triage 2021-07-27 21:19:51 UTC 
How x11@ team does QA? Each mesa* update brings tons of regressions.
Comment 2 Jan Beich freebsd_committer freebsd_triage 2021-07-28 05:46:49 UTC 
Ignore comment 1. I can't remove it due to bug 191677.
Comment 3 Emmanuel Vadot freebsd_committer freebsd_triage 2021-07-28 07:55:07 UTC 
I can confirm that too.
I don't really know why though, prefer-iris is default to true now and I see -DPREFER_IRIS passed when compiling loader.c/pci_id_driver_map.c too.
So if you have any idea I'd appriciate it, otherwise I'll need to take time to look more closely later this week.
Comment 4 Jan Beich freebsd_committer freebsd_triage 2021-07-28 10:47:07 UTC 
files/patch-src_loader_meson.build added by ports 450f410688e7 is missing.

    graphics/mesa-libs: Add back patch for iris

    Due to how the mesa ports are split we need to patch meson files so
    iris is prefered on compatible intel GPU.
