Hi Mourad,
Public protocols are those protocols for which the public or IBV have access to the include file found in one of the Include/Protocol directories. Private protocols do not typically place their include files in any of the Include/Protocols directories! Some private protocols may have public implementations while others may be delivered as a set of binary images. Note that the private protocol GUIDs are still visible on image and controller handles. Lee From: Souag, Mourad S [mailto:[email protected]] Sent: Thursday, September 13, 2012 2:16 PM To: [email protected] Subject: [edk2] public/private protocol Hello everyone, With one of my principal engineer we had a discussion about what protocol should or should not be exposed from a device driver stack. When you want to design to allow modular configuration, you may end with protocol that are used between different layers of your stack. Those protocols are private and should not be directly used by the IBV. So my question is how can a protocol be define as private or public? This concept exist in higher level framework such are .Net. This is a little representation of the problematic where a platform specific configuration driver needs to stay private: UEFI App or Driver | MydeviceProtocol(public) V My device driver | MydeviceConfigurationProtocol(private) V My device configuration driver Best Regards, Mourad Souag; Firmware Architect; MCG - Oregon; 503-264-9111 logoSponsors of TomorrowT
