Hackster ☛ Google Releases Early Patches for Running Mainline Linux on Its Pixel 10 Smartphone Family
A software engineer at Google has released the first patches in a series which could, one day, allow mainline Linux to boot on the company's Pixel 10 smartphone family — opening them up to running non-Android operating systems.
"This series adds barebones device trees for Pixel 10 (frankel), Pixel 10 Pro (blazer), and Pixel 10 Pro XL (mustang)," Google's Douglas Anderson explained in an email to the Linux Kernel Mailing List (LKML) this week. "With a yet-unreleased bootloader these can boot to a UART command prompt from an initramfs."
