any reason why 4.10.0 dropped CONFIG_GPIO_SYSFS

Postby barnabas » Wed Feb 22, 2017 10:42 am

Tried 4.10.0 and noticed that CONFIG_GPIO_SYSFS got unset. Now there is no /sys/class/gpio tree anymore. Is this intended?

Can you point out a kernel package please?

The same question.
My first try to use GPIO and found it disappeared in 4.10.0. :(

BTW, how to reach the maintainer of linux-armv7? The email in the package description bounces.

This is as good a place as any. We'll look into why this change occurred.

hmm, so linux-armv7 4.10.1-1 has re enabled CONFIG_GPIO_SYSFS. Yay!

All works great again on Scaleway C1 instances using https://github.com/stuffo/scaleway-archkernel to run Arch's kernel images.

Thanks to the maintainers.
