drm/amd/display: Send correct DP colorspace infopacket
Look at connector->colorimetry to determine output colorspace. We don't want to impact current SDR behavior, so DRM_MODE_COLORIMETRY_DEFAULT preserves current behavior. Also add support to explicitly set BT601 and BT709. v4: - Roll support for BT709 and BT601 into this patch - Add default case to avoid warnings for unhandled enum values Signed-off-by: Harry Wentland <[email protected]> Reviewed-by: Joshua Ashton <[email protected]> Cc: Pekka Paalanen <[email protected]> Cc: Sebastian Wick <[email protected]> Cc: [email protected] Cc: Joshua Ashton <[email protected]> Cc: Simon Ser <[email protected]> Cc: Melissa Wen <[email protected]> Cc: [email protected] Cc: [email protected] Signed-off-by: Alex Deucher <[email protected]>

/*
 * AFS cell record.
 *
 * This is a tricky concept to get right as it is possible to create aliases
 * simply by pointing AFSDB/SRV records for two names at the same set of VL
 * servers; it is also possible to do things like setting up two sets of VL
 * servers, one of which provides a superset of the volumes provided by the
 * other (for internal/external division, for example).
 *
 * Cells only exist in the sense that (a) a cell's name maps to a set of VL
 * servers and (b) a cell's name is used by the client to select the key to use
 * for authentication and encryption.  The cell name is not typically used in
 * the protocol.
 *
 * There is no easy way to determine if two cells are aliases or one is a
 * subset of another.
