Okay there is some update on the 2nd part.
Now I am able to successfully install all imx modules after the resume
(no hang).
But, I got some errors after install finish:
[drm] disabling vblank on crtc 1
[IMX]: imx_drm_disable_vblank - called
[drm:drm_atomic_helper_commit_cleanup_done] *ERROR* [CRTC:24:crtc-0]
flip_done timed out
Also I am able to start the weston successfully.
But I see LCD/HDMI display is not working (only some backlight is visible).
And, I noticed, weston also reports the following errors:
imx-ipuv3 2400000.ipu: DC stop timeout after 50 ms
[IMX]: drm_crtc_vblank_off - called
[IMX]: imx_drm_disable_vblank - called
INFO: rcu_preempt detected stalls on CPUs/tasks: { 1} (detected by 0,
t=6002 jiffies, g=289, c=288, q=8)
Task dump for CPU 1:
weston R running 0 306 1 0x00000000
[<c05282d8>] (__schedule) from [<00080193>] (0x80193)
Do you have any clue about these errors ?
Thanks,
Pintu
