Updating my Thinkpad X250 (Broadwell chipset) to mesa-dri/libs 20.2.3 broke direct rendering with the modesetting xorg driver. The xorg intel driver was however ok, but with it, I needed to use MESA_LOADER_DRIVER_OVERRIDE=i965 to get direct rendering. I recompiled mesa-libs without the patch patch-src_loader_meson.build, and the modesetting driver again enabled direct rendering. This is on 11.4-STABLE r369446 with drm-fbsd11.2-kmod-4.11g20200420_1. Sorry for the brevity, but can provide more info if needed!
Is iris from mesa-devel also affected? mesa-dri is both old (see below) and split in a way that caused bugs in the past. - 20.2.3 was released on 2020-11-23 (this is what in ports/ atm) - 20.2.4 was released on 2020-12-04 - 20.2.5 was released on 2020-12-16 - 20.2.6 was released on 2020-12-17 - 20.3.0 was released on 2020-12-03 - 20.3.1 was released on 2020-12-16 - 20.3.2 was released on 2020-12-30 - 20.3.3 was released on 2021-01-13 - 20.3.4 was released on 2021-01-29 - 21.0.0 was released on 2021-03-11 (In reply to Bengt Ahlgren from comment #0) > broke direct rendering with the modesetting xorg driver How does this manifest? Show Xorg.log and console output after prepending "env LIBGL_DEBUG=verbose" > xorg intel driver was however ok xf86-video-intel has DRI3 disabled by default. When using modesetting driver did you try prepending "env LIBGL_DRI3_DISABLE=1"?
No answers from reporter and it's on FreeBSD 11 which isn't supported anymore, closing.
