Please install "intel-gpu-tools", then boot with kernel parameter "blacklist=i915,snd_hda_intel modprobe.blacklist=i915,snd_hda_intel 3".
You might need to switch to other tty to see the login prompt.
Then read the register via the following command:
intel_reg read --count 20 0x64E00 0x64E60 0x64EC0 0x64F20 0x64F80
intel_reg read 0x64000 0x64100 0x64200 0x64300 0x64400 0x6C00C
