Would it be acceptable to increase the wait from 300ms to about 1500ms?
That means delaying the boot by another 1.2 seconds on all machines which have hdmi without a cable plugged in. I'm not sure I'm a fan of that.
Yes. How about if sunxi_hdmi_hpd_detect() was split into two, firstly the initialisation part that always needs to be run, and secondly the actual hpd detection, which would only be run if the hpd option to video-mode was selected?
That won't help since hpd=1 is the default, and we need to wait for the hpd signal before doing edid, and we want to do edid by default.
Another idea is that the hpd timeout value could be an additional option to video-mode.
That is probably the best solution, we may still need to tweak the default delay a bit so that it will just work in most cases, but 1.5 seconds is just too long IMHO. I've implemented this suggestion:
