The in-development Linux 7.1 kernel this week saw the integration of significant updates to its Human Interface Device (HID) and PCI subsystems. The HID subsystem changes introduce new hardware support, specifically adding drivers for the Lenovo Legion Go and expanding compatibility for various Sony HID devices. Concurrently, the PCI subsystem updates have been merged, incorporating a range of changes that include the addition of new PCIe drivers and the removal of certain older PCI drivers. These updates contribute to broader hardware compatibility and ongoing maintenance within the kernel, reflecting continued efforts in supporting modern and legacy hardware.
