35 * \brief Connected. Authenticated with DRI1 protocol.
38 * This is a deprecated authentication type. All DRI-based drivers have
39 * been migrated to use the DRI2 protocol. Newly written drivers shall
40 * use DRI2 protocol only, or a custom authentication means. e.g. opt
41 * for authenticating on the VA driver side, instead of libva side.
45 * \brief Connected. Authenticated with DRI2 protocol.
47 * This is only useful to VA/X11 drivers. The libva-x11 library provides
48 * a helper function VA_DRI2Authenticate() for authenticating the
49 * connection. However, DRI2 conformant drivers don't need to call that
50 * function since authentication happens on the libva side, implicitly.
54 * \brief Connected. Authenticated with some alternate raw protocol.
56 * This authentication mode is mainly used in non-VA/X11 drivers.
57 * Authentication happens through some alternative method, at the
58 * discretion of the VA driver implementation.
