Linux 7.1 is removing several legacy input hardware drivers that have been obsolete for decades. The removals include bus mouse drivers (InPort/Microsoft/ATI XL and Logitech Bus Mouse) that connected via ISA cards, the Palm Top PC 110 touchpad driver from 1995, the ICS MicroClock MK712 touchscreen driver, the CT82C710 PS/2 mouse interface driver used by 386/486-era laptops, and the OLPC HGPK PS/2 protocol support which has been broken since 2015 without any complaints. The input subsystem pull request accounts for 3,374 line deletions. These removals are part of a broader Linux 7.1 effort to clean up obsolete code, alongside the removal of old drivers prompted by AI/LLM bug report surges.
