imx-drm hang issue with etnaviv (GC3000)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

After running kmscube (or another KMS executable) on a i.MX6 QuadPlus (etnaviv,
GC3000) a few times on I get the below crash in the drm kernel driver.
This is on a device with LVDS panel. It is always reproducible, although the
number of invocations needed differs.

The only way to get rendering to work again after the crash is to reboot.
Repeated tries only get the "flip_done timed out".

This always happens while the program is exiting.

Versions:

- mesa: https://github.com/etnaviv/mesa 9a09984

- libdrm: https://cgit.freedesktop.org/mesa/drm/ fe4579e

- Kernel: 4.8.0 or 4.8.4 + Pengutronix patches (20161007).

Does anyone have an idea what could be the problem?

Regards,
Wladimir van der Laan
