What is bc250-cu-live-manager?

This is an interactive terminal tool for managing compute units on the AMD BC-250 graphics card. The BC-250 normally boots with 24 compute units active, controlled by the driver. This tool lets you route additional compute units at runtime using a low-level hardware access utility called UMR, potentially raising the active count from 24 to 40. Changes can be kept only for the current session, or saved and set to restore automatically after every reboot. The tool presents a live dashboard in the terminal showing which compute units are currently active, which are driver-controlled, and which the tool has enabled separately. From there you can open a table editor that lets you toggle individual units on or off, apply a preset full-40-unit layout, or restore the original factory layout. All write actions require an explicit confirmation step before any hardware registers are touched. To make a layout persist across reboots, two steps are required: saving the current live table to a configuration file, and then installing a system service that replays that file each time the machine starts. The tool includes separate menu options for each step, and also for uninstalling the service if you no longer want automatic restore. An asterisk marker in the menu indicates when the current live table differs from what is saved for boot. The tool is a single Bash script. Running it requires the AMD BC-250 hardware, the UMR utility (which the script can offer to install if missing), Python 3, and a compatible AMD GPU system library. The tool is specific to this hardware model and not intended for other graphics cards.
