Thanks, Agreed, I don't have access to hardware with _PR3 support to install the Qualcomm devices - all my testing for these has been on platforms without _PR3 (desktop M.2 adapters). I'll drop the general d3cold infrastructure (patch 1/3) entirely and simplify patch 2/3 to just a D3hot-only device-specific reset for the specific Qualcomm devices where testing shows it works despite NoSoftRst+. v9 coming soon. Thanks, Best regards Jose Ignacio
