The Linux 7.2 update arrives with a background cleanup: it removes two hardware drivers that have been unused for years. One is a voice synthesizer for ISA computers; the other, an industrial communication controller for factories. Both date back to 1998 and lacked maintenance and active users. For the general public, the change goes unnoticed on modern equipment, but it reduces the system's size and improves its security.
Less legacy code, more kernel efficiency 🧹
The removal of these drivers responds to a common practice in kernel development: removing code that no longer receives patches or testing. The ISA voice synthesizer relied on nearly extinct hardware, while the industrial controller operated on obsolete protocols. By removing these lines, the system reduces its attack surface and frees up resources during compilation. Developers thus prioritize kernel stability without dragging along legacy code that no one verifies.
Goodbye to the synthesizer no one heard speak 🤫
The ISA voice synthesizer leaves without making a sound, which is exactly what it had been doing since 1998. It remains to be seen if some hobbyist was using it to read their computer the riot act, or if the industrial controller was still running some machine in a ghost factory. What is certain is that Linux saves itself the weight of two hardware ghosts. As an old admin would say: if no one misses it, it was surplus.
