This is the core of the seapath project. The meta-seapath repo contains the yocto Seapath layer, which contains all the code (yocto recipes) needed to build the seapath images used to install seapath (host, guest, flasher, etc.)
IRQBALANCE_BANNED_CPULIST is an environment variable from irqbalance used to ban CPU core on IRQ threads. It can be used with a range syntax such as 2-10 to exclude cores 2 to 10 on IRQ threads.
Currently, we used it using for example 4-N, where N is the number max of core available. This syntax is not supported by irqbalance, causing to ignore the variable.
To fix it, this commit adds the call of a script in prelaunch task of the irqbalance deamon, which retrieve the number max of CPU core available and set it correctly in the irqbalance.env environnement file.
