Subject: [PATCH net-next 5/6] mlxsw: core: Expose MFDE.log_ip to devlink health
Date: Wed, 10 Mar 2021 13:02:19 +0200 [thread overview]
Message-ID: <20210310110220.2534350-6-idosch@idosch.org> (raw)
In-Reply-To: <20210310110220.2534350-1-idosch@idosch.org>
From: Danielle Ratson <danieller@nvidia.com>
Add the MFDE.log_ip field to devlink health reporter in order to ease
firmware debug. This field encodes the instruction pointer that triggered
the CR space timeout.
