This patch set adds a new drm driver for Hisilicon Hibmc. Hibmc is a
BMC SoC with a display controller intergrated, 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 v5:
-rebase on v4.9-rc2.
-replace drm_fb_helper_set_suspend() with
drm_fb_helper_set_suspend_unlocked(), remove redundant console_lock()
and console_unlock().
Changes in v4:
-remove unused include files, and include header file when it is needed.
-remove unused FLAG in Kconfig: DRM_GEM_CMA_HELPER/DRM_KMS_CMA_HELPER.
-remove drm_helper_disable_unused_functions, since we use DRIVER_ATOMIC.
Changes in v3:
-enable KMS, in v2, only fbdev is enabled.
-management video memory with ttm.
-add vblank interrupt.
-remove drm_connector_register_all() and drm_connector_unregister_all().
-I have a basic test with igt.
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().
