Hi Ke Liping!
The xen mca public header needs some comment updates in the xen tree first
before it populates to the guests:
In line 102, uncorrectable errors are not reported via nmi handlers.
Please update the comment to match the code.
In struct mcinfo_recovery, it is not obvious that the REC_ACTION_* flags are
intended to be used in action_flags. Please add a comment to make this clear.
In struct mcinfo_recovery, it is not obvious that the MC_ACTION_* flags are
intended to be used in action_types. Actually are these flags?
These are defined as a bitfield, but the union can't store more than one
action. Please add a comment to clarify this.
For xen_mc_notifydomain, it is not clear if this has to be used before or
after acknowledging the fetched telemetry. Please update the comment
to clarify this.
In xen_mc_notifydomain, the comment this the flags field may contain
XEN_MC_TRAP which doesn't exist. Please update the comment.
