[PATCH 0/9] drm/ast: Transparently handle BMC in outputs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add transparent BMC support to all outputs. If the user disconnects
the physical display, each output will now return display modes for
the BMC. Makes the BMC connector obsolete, so remove it.

The benefit of the new approach is that is works with any userspace.
Most userspace compositors have problems configuring the current BMC
connector. The BMC connector is now gone and only a physical connector
is present.

Also clean up some of the EDID handling in preparation. Switching to
struct drm_edid and its helpers simplifies the code for inclusion of
the BMC support.

A similar approach has been taken for mgag200. [1] Here a server's
display hardware also contains an internal BMC that needs to display
even without the presence of a physical display.
