[SOLVED] Raspberry GPIO not working

[pacl]

Hello together,

I installed Gentoo 64 Bit on a Raspberry Pi 3 and I'm struggling with the GPIO interface.
I2C works fine over GPIO (I'm updating system time from an I2C connected RTC).

But, when I'm using MMIO
https://github.com/adafruit/Adafruit_Python_DHT/blob/master/source/Raspberry_Pi_2/pi_2_mmio.c
or wiringPi to access/modify the GPIO pins (turn on LED for instance), nothing works.

I'm aware that MMIO used the BCM codes and wiringPi their own pin identifier.

I have the Raspbian installed on a different SD-card, where MMIO and wiringPi work without any issues.

One thing I noticed:
The wiringPiSetup reads the /proc/cpuinfo file and looks for some hardware specific information:
https://github.com/WiringPi/WiringPi/blob/master/wiringPi/wiringPi.c (line 688).
But in Gentoo, the appropriate lines don't exist.
I would like to have the wiringPiSetup working out of box, rather than patching a workaround.

/proc/cpuinfo:

Additional /proc/cpuinfo lines in Raspbian:

Hmm,

it works now with MMIO, but not with wiringPi, because of /proc/cpuinfo.
I can live with that.
