Hi,
This series is a DRM driver for StarFive SoC JH7110, which includes a display controller driver for Verisilicon DC8200 and an HMDI driver.
We use GEM framework for buffer management and allocate memory by using DMA APIs.
The JH7110 display subsystem includes a display controller Verisilicon DC8200 and an HDMI transmitter. The HDMI TX IP is designed for transmitting video and audio data from DC8200 to a display device. The HDMI TX IP consists of the digital controller and the physical layer.
This series does not support HDMI audio driver.
