Description

Hi,

I suspect we want to eventually rename/alias 'flash' to 'run'. And treat qemu emulation as just another runner backend. I believe this would make it easier for us to maintain the runner and qemu infrastructure, and would make it easier for us to keep the user-interface for flashing and running consistent.

A qemu backend would also allow us to move all the symlink/fifo/pipehandling out of qemu.cmake and into a python runner backend.

It is not clear how difficult it would be to do this.

Direção de pesquisa
Examine qemu.cmake in the Zephyr repository to understand current symlink/fifo/pipe handling. Review discussion in issue #5501, particularly comments from maintainers regarding the desired runner backend interface. Investigate existing runner backends in the Python scripts directory to model a new QEMU backend. Propose a plan to move QEMU specific logic out of CMake and into Python, ensuring backward compatibility for the 'flash' command.
