Hardware Support¶
Current upstreaming efforts are focused around the S905/S905D/S905X/S805X/S905W/S912/A113D/S905X2/S905D2/S905X3/S905D3/A311D/S922X SoCs (GXBB/GXL/GXM from the Meson GX family, AGX Family and the new G12A, G12B & SM1 Families). Secondarily there are also some efforts around the S805 SoC (Meson8b), and the AML8726-MX (Meson6) since they are widespread in many consumer products.
An upstreaming effort is ongoing for the S4 family (S805X2/S905Y4).
What about multimedia support ?¶
Here is current status on Multimedia support :
GPU : Is supported on S905, S905X/W/L, S905D, S805X, S912, S905X2, S905D2, S905X3, S905D3, A311D and S922X with Lima and Panfrost
Linux drivers upstream since v5.2
Mesa support in master : https://gitlab.freedesktop.org/mesa/mesa
Closed Source mali driver using https://github.com/superna9999/meson_gx_mali_450 driver and https://github.com/superna9999/amlogic-meson-mali binaires (The ARM provided HiKey binaries are also functional)
HDMI Output up to 4k is working on S905, S905X/W/L, S905D, S912, S805X, S905X2, S905Y2, S905D2, S922X, A311D, S905X3, S905D3, S905Y3
Video Decoding is being upstream, but still in Staging until the Statefull V4L2 M2M Interface is finalized, supports MPEG-2, H264 and VP9 decoding
All of this is being integrated in a specific LibreELEC branch at : https://github.com/LibreELEC/LibreELEC.tv/tree/amlogic and https://github.com/chewitt/LibreELEC.tv/tree/amlogic
And Android/AOSP ?¶
Yes, we (BayLibre) pushed an upstream based AOSP support for the G12A/SM1 based boards :
SEI510
SEI610
Khadas VIM3L
Khadas VIM3
Current status (Oct 2020):
Android 11 Bootflow using Mainline U-Boot
Mali GPU using binary blobs
Audio support (HDMI, analog, dmic)
