Description David Heidelberg (okias) 2019-09-02 10:33:10 UTC
HW: Dell 7350 Intel HD520.
SW: Gentoo, kernel 5.2.11, ~amd64, Wayland setup.

When using
MESA_LOADER_DRIVER_OVERRIDE=iris
in /etc/environment, gdm freeze. Only printed lines into logs are:

gnome-shell[932]: meta_drm_buffer_gbm_new failed: drmModeAddFB failed: Nepřípustný argument (translated as Unacceptable argument)
gnome-shell[932]: meta_drm_buffer_gbm_new failed: drmModeAddFB failed: Nepřípustný argument (translated as Unacceptable argument)

I tried compile git mesa with debug, but it didn't get me further.

Feel free to ask me to get specific debugging, can compile mesa/libdrm or kernel with specific patches.

Hello David, thanks for the report.

I've reproduced the issue on my SKL (Intel® HD Graphics 520) with ubuntu 18.04 and mesa commit cf652205cff25dbb0d8c0f642f8a6d097e51a010 (around the first commit with iris support).
The machine freezes when Wayland is set and MESA_LOADER_DRIVER_OVERRIDE=iris enabled.
Also, I've tried to reproduce the issue on my KBL (Intel® UHD Graphics 620) - no freeze.

I attach journalctl log
Comment 2 Paul 2019-09-11 14:28:02 UTC
UPD - the issue is also actual on KBL (Intel® UHD Graphics 620).

Also, I've checked the issue with the latest version of drm-tip - the issue is also actual.
