Mika Westerberg 24740385cb thunderbolt: Improve redrive mode handling ... When USB-C monitor is connected directly to Intel Barlow Ridge host, it goes into "redrive" mode that basically routes the DisplayPort signals directly from the GPU to the USB-C monitor without any tunneling needed. However, the host router must be powered on for this to work. Aaron reported that there are a couple of cases where this will not work with the current code: - Booting with USB-C monitor plugged in. - Plugging in USB-C monitor when the host router is in sleep state (runtime suspended). - Plugging in USB-C device while the system is in system sleep state. In all these cases once the host router is runtime suspended the picture on the connected USB-C display disappears too. This is certainly not what the user expected. For this reason improve the redrive mode handling to keep the host router from runtime suspending when detect that any of the above cases is happening.
