A true mainline Linux Kernel for the Pinebook Pro
#1
Hi all,

I've built a true mainline Linux Kernel for the Pinebook Pro. It does only have a minimal amount of patches required to support
  • the eDP panel Mainlined
  • the battery fuel gauge (Mainlining in progress)
  • the Pinebook Pro devicetree (Mainline starting 5.7) Mainlined in 5.7
  • USB-C DP altmode
  • Rockchip SIP driver
  • Ultra low power sleep

I do plan on mainlining those patches ASAP.

Display and graphics work using panfrost (xf86-video-fbturbo is not required if your mesa build is recent and has panfrost support). The whole device does pretty much just work as you would expect it to do.

At the moment there are a few caveats:
  • WiFi seems to be unstable, possibly due to issues with the Broadcom firmware and power management Fixed
  • Bluetooth is untested Works through hciattach, actual native support through hci_uart would be great though Migrated to hci_uart and stable
  • PCIe is untested PCIe works just fine
  • Sound does not work (wip) Fixed though pinctrl
  • Bootup takes a long time (~ 3 minutes) since the kernel hangs twice for quite some time during boot Workaround through new defconfig
  • Charging via USB-C does not work Fixed though some devicetree adjustments
  • Device does not power down fully Workaround in the rk808 driver, proper support in the ATF would be nice
  • USB-C DP altmode does not work Fixed, with USB 3.1 gen 2 support
  • Suspend to RAM is not working Fixed through forward port of SIP driver. Works only with BSP U-Boot, gives > 200 h standby

Development is taking place in the Manjaro gitlab:  https://gitlab.manjaro.org/tsys/linux-pinebook-pro


Have a nice day,
