Nice it's the same driver written a little bit differently. I did not see his patch before. 2 things missing in Sashis driver which are useful for me: 1. Add sbsa watchdog to machine virt also. That helped me to reboot a virtual machine with secure payload. 2. I specially did not disable timer on driver close. I.e. "reboot" linux path reboots with that watchdog. And make timeout lower to not wait for a long period. Can this driver also be considered for virt machine? Regards, Maxim.
