From c8e1da0bf9238e460c73ebc5a07ce93697e5e207 Mon Sep 17 00:00:00 2001 From: Eran Ben Elisha Date: Thu, 7 Feb 2019 11:36:34 +0200 Subject: devlink: Add health report functionality Upon error discover, every driver can report it to the devlink health mechanism via devlink_health_report function, using the appropriate reporter registered to it. Driver can pass error specific context which will be delivered to it as part of the dump / recovery callbacks. Once an error is reported, devlink health will do the following actions: * A log is being send to the kernel trace events buffer * Health status and statistics are being updated for the reporter instance * Object dump is being taken and stored at the reporter instance (as long as there is no other dump which is already stored) * Auto recovery attempt is being done. Depends on: - Auto Recovery configuration - Grace period vs. Time since last recover Signed-off-by: Eran Ben Elisha Reviewed-by: Moshe Shemesh Acked-by: Jiri Pirko Signed-off-by: David S.
