Hello, I am re-spinning the patches as last time I accidentally sent v2 twice without bumping the version. 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: v2 -> current: * fixed the build error reported by the Intel robot (https://lore.kernel.org/all/202406132132.FBKSWFav-lkp@xxxxxxxxx/) * v2 was sent mistakenly on the list without bumping the version to v3. v3 should be the correct version of this patch. v1 -> v2: * 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 Link to v2: https://lore.kernel.org/all/20240611110136.2003137-2-sebastianene@xxxxxxxxxx/ Link to v1: https://lore.kernel.org/all/20240523160413.868830-1-sebastianene@xxxxxxxxxx/ Thanks, Sebastian Ene (2): dt-bindings: vcpu_stall_detector: Add a PPI interrupt to the virtual device misc: Register a PPI for the vcpu stall detection virtual device .../misc/qemu,vcpu-stall-detector.yaml | 6 ++++ drivers/misc/vcpu_stall_detector.c | 31 +++++++++++++++++-- 2 files changed, 35 insertions(+), 2 deletions(-) -- 2.45.2.803.g4e1b14247a-goog
