still in progress for proper serial. for now, I am entering in ddb via MP_LOCKDEBUG (I think, I didn't check previously if bindly enter ddb commands worked) and I bindly enter ddb commands before rebooting, disabling amdgpu* and grab the dmesg buffer to see output of my commands. > dmesg with firmware present > trace/ps etc if it is in ddb > or send a break over serial to enter ddb with ddb.console=1 then get trace/ps The output below is from GENERIC.MP compiled with: MP_LOCKDEBUG + WITNESS + DRM_DEBUG with latest -current (528fdf61709e1aaadc178de57ca5b705e9d2b233). The mainboard has several connectors for output: - HDMI - VGA - DVI The screen is on VGA. Others connectors are not connected.
