pigpio: Cannot start pigpiod: mmap gpio failed

Hi, I know this issue has already been talked about, but I got the following issue: running sudo pigpiod returns:

initPeripherals: mmap gpio failed (Operation not permitted)
Can't initialise pigpio library

I tried adding iomem=relaxed to the boot parameters (which applied correcly as stated by /proc/cmdline), same result.

I also see the issue with 32bit Ubuntu 20 server on RP3 and I can confirm the fix (removing PROT_EXEC) works.

Libgpiod https://git.kernel.org/pub/scm/libs/libgpiod/libgpiod.git/ - but it does not support PWM.
