Hello guys

I can see the following boot log with v4.17-rc1

[ 7.102212] mali: loading out-of-tree module taints kernel. [ 7.114803] Allwinner sunXi mali glue initialized [ 7.296953] Mali: ERR: /home/sergey/Projects/orpaltech/drivers/sunxi/sunxi-mali/r6p2/src/devicedrv/mali/common/mali_pp.c [ 7.307913] mali_pp_reset_wait() 269

The error is coming from here https://github.com/mripard/sunxi-mali/blob/a5b9f18a165fb3c5d2bc4a0219a0c626bc72450e/r6p2/src/devicedrv/mali/common/mali_pp.c#L268 and is somehow related to hardware reset.

Any ideas ? It worked well with 4.16.

As usual, without a commit ID, SoC, board and config file, we can't help you.

sergey-suloev commented 6 years ago

Thanks, it has been resolved.

Resolved by 4.17-rc2 or something else you did?

sergey-suloev commented 6 years ago

@Halolo I don't know. I was making many builds that evening and after 3-4 builds it was resolved with rc1. There might additional commits happen during that time period.

Same issue with 4.17.4 kernel on Orange Pi Lite running bionic nightly build. Even the error codes are same. What info i must provide? config-4.17.4-sunxi.txt dmesg.txt

P.S. Downgraded to 4.17.2 - same error.
