Subject: [PATCH v2 0/2] misc: vcpu_stall_detector: Add a PPI interrupt
Date: Tue, 11 Jun 2024 11:01:35 +0000	[thread overview]
Message-ID: <20240611110136.2003137-2-sebastianene@google.com> (raw)

Hello,


This is a small update of the previously introduced vcpu stall detector
which adds an interrupt to the virtual device to notify the guest VM in
case it stalls. This lets the guest VM to handle the reboot and to
panic in case it expires. 

Changelog from v1:

* 1/2 : collected the Ack from Conor Dooley, thank you Conor !

* 2/2 : applied the feedback received from Conor and used
	platform_get_irq_optional. Removed the error messages during
	probe
   

Thanks,
