This patch set adds a new drm driver for Hisilicon Hibmc. Hibmc is a base board management controller, usually it is used on server for Out-of-band management purpose. In this patch set, we just support basic function for Hibmc display subsystem. Hibmc display subsystem is connected to host CPU by PCIe as blow:
+----------+ +----------+ | | PCIe | Hibmc | |host CPU( |<----->| display | |arm64,x86)| |subsystem | +----------+ +----------+
Hardware Detail for Hibmc display subsystem -----------
The display subsystem of Hibmc is show as bellow: +----+ +----+ +----+ +--------+ | | | | | | | | | FB |----->| DE |----->|VDAC|---->|external| | | | | | | | VGA | +----+ +----+ +----+ +--------+
-DE(Display Engine) is the display controller. -VDAC(Video Digital-to-Analog converter) converts the RGB diaital data stream from DE to VGA analog signals.
Change History ------------
Changes in v2: -Remove self-defined macros for bit operations. -Remove unused register. -Replace those deprecated functions with new version of them. -use drm_connector_register_all() to register connector after drm_dev_register().
The patch v1 is at https://lists.freedesktop.org/archives/dri-devel/2016-February/101921.html Sorry for too late sending.
