H3

Allwinner H3 (sun8iw7p1) SoC features a Quad-Core Cortex-A7 ARM CPU, and a Mali400 MP2 GPU from ARM. The Allwinner H3 is a highly cost-efficient quad-core OTT box processor, primarily marketed as being for "home entertainment" systems.

'''It's rated to run at 1.296GHz, anything higher is overclocking (and usually overvolting). If you run it without heatsink, fan and proper dvfs settings, you risk overheating.'''

=Overview= Currently, there is no sunxi support available yet. SDK has been released in May-2015, and devices are slowly becoming available.

= Mainline status = U-Boot already supports the H3 SoC at least since 2016.01-rc3 and has defconfigs for Orange Pi PC and Xunlong Orange Pi Plus boards.

Also initial H3 patches have been submitted to the mainline kernel, but have not landed yet. Currently you can find the patches in the arm-linux mailing list, or alternatively in one of the work-in-progress kernel forks:
 * Hans de Goede's branch sunxi-wip at https://github.com/jwrdegoede/linux-sunxi
