Mkay, per our irc discussion (pls add Ville to the cc of this patch) we
need one more bit:
In the pipe state compare functions, when the old mode is inherited and
either has_infoframes or has_audio (because of the eld crap) is set, then
we need to force a full modeset. Since atm we don't patch that up
properly. Maybe wrap that logic up into a PIPE_CONF_INCOMPLETE_STATE_CHECK
macro or something like that:
#define PIPE_CONF_INCOMPLETE_STATE_CHECK(name)
if (current_config->flags & INHERITED) {
if (current_config->name || pipe_config->name) {
pipe_config_err(...)
ret = false;
}
}
Or something like that.
With that fixed I think/hope we're finally done with this thing.
