Here is a brief summary of what's working upstream as of this week: - Display - X11, Wayland, and text mode work. No GPU yet however out of tree patches are available. I'm slowly working on proper support for inclusion upstream. - Display backlight - Touchscreen - WiFi - USB - gyroscope / accelerometer - magnetometer - temperature / humidity / barometer - proximity / ambient light sensor (ALS) - Charger - Serial port See https://masneyb.github.io/nexus-5-upstream/ for more details. I created a TODO list at https://masneyb.github.io/nexus-5-upstream/TODO.html with links to existing out-of-tree code in case anyone out there is looking for a project. The Nexus 5 uses the Qualcomm msm8974 SoC, and some of this work (such as the display) should help other devices like the Fairphone 2, OnePlus One, Samsung Galaxy S5, Sony Xperia Z1, and Sony Xperia Z2 tablets. postmarketOS (https://postmarketos.org/) can be used as the userspace to run the latest version of Alpine Linux. Thank you to all of the maintainers and reviewers that have provided feedback on this work. I picked this up as a side project last year and have learned a lot doing this. Brian
