What do you work on?
Devices and SoCs I work on:
Xiaomi Mi Note 2
Qualcomm Snapdragon 821 (MSM8996 Pro)
I work on this device the most, thanks to the good initial mainline support for the MSM8996 SoC.
Samsung Galaxy Grand Prime+
This device has a broken ARM Trusted Firmware implementation that makes it impossible to boot a 64-bit OS despite having ARMv8 CPUs. It also lacks PSCI, so booting the remaining 3 CPUs is not possible without a special driver. That is perhaps made clear by the single Tux showing up:
Lenovo IdeaTab A3000
This is an old SoC with 4x ARM Cortex-A7 CPUs and a PowerVR SGX544 GPU, which unfortunately has no open source driver.
