Hi All,
The first patch is a better alternative to the previously posted
patch ("drm/fsl-dcu: only init fbdev if required") as suggested
by Daniel.
The second and third are fix related issue uncovered during tests
with bind/unbind:
echo 40058000.dcu > /sys/bus/platform/drivers/fsl-dcu/unbind
echo 40058000.dcu > /sys/bus/platform/drivers/fsl-dcu/bind
Especially the third patch I am not sure if that is a reasonable
strategy to fix the issue. I did not saw another SoC DRM driver
which is making use of drm_crtc_force_disable_all...
Also, when the X Server is running (with modesetting driver) I
still get a warning:
WARNING: CPU: 0 PID: 452 at drivers/gpu/drm/drm_crtc.c:1154 drm_mode_config_cleanup+0x210/0x220
The comment says it is the drivers fault, but as far as I can
tell it is user space which does not free up this framebuffers.
Is there something missing in my driver?
Any ideas?
