WARNING: This device is not recommended for future use with postmarketOS due to its armhf architecture. Alpine Linux (the distribution that postmarketOS extends) pmaports#599 has been considering dropping it.

This device is still running on armhf, although the processor supports armv7. If you own it, change it and test it that way.

Hardware details

Chipset

The basic chipset is MSM8x74 ("x" denotes the modem code), but conformance to a particular device table on that link are not clear. Below is a superficial, pmos-independent attempt to determine the chipset details from userland. The test device is a 2GB/16GB Mi 3 (WCDMA 2013062 2014 stenciled on back case, below silver "mi" emblem), running twrp 3.1.1-0. Reference values are from Wikipedia.

kernel	3.4.0-g83662a8-01427-gad51ea1	Dec 2014
Hardware	Qualcomm MSM8974PRO-AB	implies Snapdragon 801?
CPU max freq (KHz?)	2265600	800AA, 801AA v3 or underclocked AB?
CPU min freq (KHz?)	300000
GPU	?
GPU max freq (Hz?)	578000000	adreno 330? 800AB, or 801AB v3? need GPU stresser & GPU freq stats to confirm
GPU max-1 freq (Hz?)	462400000	adreno 330 (450MHz)? 800AA, or 801AA v3?
GPU min freq (Hz?)	200000000
GPU target freq (Hz?)	330000000	= min+1 freq. decided by governor?
EMMC	?.?	800 is 4.5, 801 is 5.0?
