Sorry, that was file size. Here is the “arm-rtems5-size” equivalent output for
each test.

May be RTEMS can support only SPI, I2C input devices?
If somebody want to use USB input devices, they will use RTEMS LIBBSD.

Posting inline be
I think that is doable for the frame buffer and non-USB touch screen, mouse,
and keyboard drivers. The main problem would be the USB mouse, keyboard, and
touch screen drivers. RTEMS uses LIBBSD for the USB stack.

So the minimal example of Qt Widgets + RTEMS LIBBSD + EVDEV will be ~24MB.
It is pretty big. If RTEMS has support of EVDEV or libinput it will be only
~9MB.
Qt does not require MMAP, only LinuxFB plugin. I wrote my own QPA plugin
and it does not need MMAP.

To give a little background on this subject, the current support in RTEMS
LIBBSD for the EVDEV input system was motivated by the following:
- Add a “rtems-arm-4.12-gcc” platform to QT. This allows you to configure QT
with RTEMS compilers and libraries.
- Use QT LinuxFB plugin as is for graphics

That's the question.
RTEMS LIBBSD has support for EVDEV which is a standard API for keyboard, mouse,
and touchscreen. Is it the best choice, I don't know. Maybe a better question
is "What standard input system should RTEMS support?".
