The FOSDEM conference took place this week-end in Brussels. Besides the almost 500 talks that took place in the official schedule, a discussion about the Common Display Framework was organized on Sunday morning. Laurent Pinchart, who currently leads the discussion on this framework, posted a report of those discussions.
In his report, Laurent explains:
CDF has two main purposes. The original goal was to support display panels in a platform- and subsystem-independent way. While mostly useful for embedded systems, the emergence of platforms such as Intel Medfield and ARM-based PCs that blends the embedded and PC worlds makes panel support useful for the PC world as well.
The second purpose is to provide a cross-subsystem interface to support video encoders. The idea originally came from a generalisation of the original RFC that supported panels only. While encoder support is considered as lower priority than display panel support by developers focussed on display controller driver (Intel, Renesas, ST Ericsson, TI), companies that produce video encoders (Analog Devices, and likely others) don’t share that point of view and would like to provide a single encoder driver that can be used in both KMS and V4L2 drivers.
