Subject: [net-next 05/16] net/mlx5e: Extend tx reporter diagnostics output
Date: Thu, 15 Aug 2019 19:09:56 +0000 [thread overview]
Message-ID: <20190815190911.12050-6-saeedm@mellanox.com> (raw)
In-Reply-To: <20190815190911.12050-1-saeedm@mellanox.com>
From: Aya Levin <ayal@mellanox.com>
Enhance tx reporter's diagnostics output to include: information common
to all SQs: SQ size, SQ stride size.
In addition add channel ix, tc, txq ix, cc and pc.
$ devlink health diagnose pci/0000:00:0b.0 reporter tx
Common config:
SQ:
stride size: 64 size: 1024
SQs:
channel ix: 0 tc: 0 txq ix: 0 sqn: 4307 HW state: 1 stopped: false cc: 0 pc: 0
channel ix: 1 tc: 0 txq ix: 1 sqn: 4312 HW state: 1 stopped: false cc: 0 pc: 0
channel ix: 2 tc: 0 txq ix: 2 sqn: 4317 HW state: 1 stopped: false cc: 0 pc: 0
channel ix: 3 tc: 0 txq ix: 3 sqn: 4322 HW state: 1 stopped: false cc: 0 pc: 0
$ devlink health diagnose pci/0000:00:0b.0 reporter tx -jp
