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
