This page only contains some info, data and links regarding mainline on Exynos SoCs. If you want to mainline a device please follow the Mainlining guide.

The mainline kernel has (at least some) support for several Exynos SoCs:

  • Exynos 3250
  • Exynos 4210
  • Exynos 4412
  • Exynos 5250
  • Exynos 5260
  • Exynos 5410
  • Exynos 5420
  • Exynos 5422
  • Exynos 5433
  • Exynos 5800
  • Exynos 7 (some early version of Exynos 7420 [1])
  • Exynos 7885
  • Exynos 850
  • Exynos Auto v9

Other variants

Currently, there are mainline development repositories for Exynos4 and Exynos5 at gitlab: https://gitlab.com/exynos4-mainline/linux, https://gitlab.com/exynos5-mainline/linux. Tags in those repositories are used for building postmarketos's linux-postmarketos-exynos{4,5} packages. For these two Exynos variants there are dedicated wiki pages, see Exynos4 and Exynos5. There is also a page dedicated to Exynos 5433: Samsung Exynos 5433 Octa.

None of the other Exynos variants have repositories or packages that can be used in postmarketos, though there are some development going on somewhere. Some repositories that that could be interesting include:

  • PabloPL's repository contains branches related to Exynos 7420, 7580, 8890
  • dsankouski's repository contains branches related to Exynos 7880
  • VDavid003's repository contains branches related to Exynos 7885
  • ivoszbg's repository contains branches related to Exynos 8895
  • krzk's repository contains branches with several vendor (Samsung) kernel sources for many Exynos SoCs

Samsung's stock bootloader expects devicetree in a certain format, and modifies the device tree before booting kernel. This is pretty inconvenient when testing mainline kernels, and so it is a good idea to use a secondary bootloader and boot mainline from it. U-boot does not support modern Exynos SoCs, but there are some other small bootloaders/kernel wrappers that can be used:

  • minimal_sboot_wrapper, wrapper to make it possible to boot mainline kernels with Samsung's Sboot bootloader (made for Exynos 7885)
  • uniloader, inspired by minimal_sboot_wrapper but with support for more Exynos variants and with more features
