I have a bit of a different idea about the whole YOCTO process.

Hi Yocto group,
I'm working with a newly-released copy of Yocto Zeus from Variscite for the
i.MX8MM Mini, although the same option seems to apply to the previous Yocto
Warrior.
I understand that a Linux real-time kernel can be enabled by setting
LINUX_KERNEL_TYPE = "preempt-rt". Where does
Thanks, Quentin, I'll take a look at Jozef's videos as time permits. Getting
lots of time pressure to get something working, and even our SoM vendor
provides examples that modify local.conf... so much for helping us with the
"right" way to do things. I appreciate your advice, and can now see
Thanks for the tip, Joel. I'm still new to this. How should libgpiod-dev be
added to my local.conf?
Do I just need to add it to EXTRA_IMAGE_FEATURES? Do I still need to add
libgpiod to IMAGE_INSTALL_append?
Your help is greatly appreciated!

I should also note that gpioinfo and other tools from libgpiod run as expected
on the target, and that /usr/lib has libgpiod.so.2 (libgpiod.so.2.1.1) in it.
I would also like the header file to be put into the image so that I can
build/run executables using libgpiod on the target.
I'm using Yocto Warrior 4.19.35 on a Variscite i.MX8M MINI SoM. I need to be
able to respond to some interrupt events on GPIO events from userspace.
I saw on kernel.org that the sysfs ABI is being deprecated, and the
recommendation is to use libgpiod.
In Yocto Warrior, it appears that the default scheduler configuration is
SCHED_NORMAL. We are trying to do some time-critical I/O, and it seems like we
may be missing some data. I'd like to increase the thread priority for our
data acquisition, but am not sure how to do so.
Is it possible to
