The Linux 7.1 kernel is making some significant changes by removing outdated hardware drivers. This move aligns with the current push to streamline the system, partly due to an increase in AI-related bug reports. The input subsystem has seen several decades-old drivers retired, reflecting technological advancements and shifting user needs.
This update introduces a few new drivers. There’s now support for a Charlieplex GPIO keypad and enhancements for the aw86927 driver, which adds compatibility for specific ASICs. Additionally, the Chrome OS keyboard driver has been updated to include support for a new Fn-key keymap extension.
On the flip side, several antiquated drivers are being phased out. For instance, bus mouse drivers, once popular, haven’t been relevant for almost 30 years. Drivers associated with portable devices from the late 1990s and early 2000s are also part of this cleanup. One such driver is the InPort/Microsoft/ATI XL bus mouse driver, which required an ISA add-in card from a time long gone. The Logitech Bus Mouse driver, designed for the same purpose, is also removed.
Another notable removal is the driver for the Palm Top PC 110 touchpad, which dates back to 1995. Similarly, the ICS MicroClock MK712 touchscreen driver, used by a handful of devices in 2000, is being tossed aside.
Oddly enough, even some newer hardware is also being cleared out, like the OLPC HGPK PS/2 protocol support—this has been broken for over a decade, with minimal user complaints.
As Linux 7.1 evolves, it’s clear that the focus is on maintaining relevance and efficiency. The removals account for 3,374 deletions in the input subsystem, illustrating a commitment to a leaner and more modern operating environment.
According to recent surveys, many users appreciate these updates, understanding that they represent an effort to adapt to newer technologies. As we move forward, it’s essential to recognize this balance between preserving legacy systems and embracing innovation in tech.
