Hi Lucas, hi Marek,
while doing some tests on i.MX8MM with Etnaviv and mxsfb-drm (using the
patches for DSIM, GPC, BLK-CTL, etc., see branch at [1]), I noticed that
I don't seem to be able to run glmark2:
~# glmark2-es2-drm
=======================================================
glmark2 2017.07
=======================================================
OpenGL Information
GL_VENDOR: etnaviv
GL_RENDERER: Vivante GC600 rev 4653
GL_VERSION: OpenGL ES 2.0 Mesa 20.2.4
=======================================================
[build] use-vbo=false:Error: Failed to create FB: -22
Segmentation fault
Running a Qt application with the eglfs_kms backend produces a similar
error, while running kmscube or applications without GPU rendering works
fine.
What am I missing? When I used imx-drm, I didn't have any such issues.
How is mxsfb-drm different?
Thanks in advance
Frieder
