Mainline Linux on AmLogic SoCs
Talkat Embedded Linux Conference + OpenIoT Summit North America 2017 · on Thursday, 2017-02-23· at 12:10· Atrium Ballroom·
summary
Mainline Linux gains concrete AmLogic support: boot, MMC, USB, clock, RNG, IR, PWM and a minimal DRM display stack are upstreamed and working on the 64-bit S905/S905X/S912 family; scpi DVFS support lands via separate drivers and device tree nodes; the effort produces 60 commits, ~6,000 lines changed by the end of the cycle. eMMC/SD performance gets major attention (community patches push to 140 MB/s MMC observed), I2S over HDMI and basic video pipelines run, and next targets are HDMI controller, overlay/cursor planes and upstream 10‑bit VP9 video decode.
