Is this really a fatal error? Or do we want to mandate that gapless be supported by all implementations?
Fatal err? if DSP doesnt support metadata callback then we are reporting error ENXIO to userpsace. No we shouldnt mandate, its upto DSP folks to see what they should and can support.
Well, up to userspace to see how it handles the error anyway. For example an application may want to fall back to PCM playback with gapless done on the CPU if the driver doesn't do it. But then given that there's more than one piece of metadata in the struct perhaps we need some way for the application to figure out what's supported?
