Introduction

This page discusses kernel changes which would help postmarketOS to support Accessibility (Packages), etc.

Kernel Mods

Serial Adapters

Dave Mielke (BRLTTY's developer) says: It'd be very cool for the kernel to have support for all known USB-to-serial adapters, plus any indirectly needed serial support, enabled. That way, those with older braille devices that only have a serial port would benefit for the mere extra cost of the adapter cable. Sure would beat having to purchase a newer braille device.

Martijn Braam says: It depends on the device, of course, but I don't think adding support for usb-serial adapters would be a problem. I already did that to test some things on the PinePhone. I guess enabling prolific, ftdi, and ch340 would cover most adapter cables. Unfortunately, it would be a per-device kernel tweak. I'm not sure how much devices have usb serial support built in already. The allwinner kernel only has CH341 support currently. It looks like the generic driver is 14.4KB and ch341 adds 4.7KB. Serial drivers aren't really big...
