It has Mani's Reviewed-by and has been tested over 100+ VM crash/reset cycles. The approach was developed following Alex's and Mani's guidance through the series, using device-specific hardware reset registers. Without this, Qualcomm WLAN and modem devices cannot be reused after unclean VM termination in VFIO passthrough. Could you help me to know if there is anything blocking this in order to move forward? Thanks Jose Ignacio
