Subject: [PATCH net-next v2 0/6] net/mlx5: Memory optimizations
Date: Wed, 8 Dec 2021 09:00:00 +0200 [thread overview]
Message-ID: <20211208070006.13100-1-shayd@nvidia.com> (raw)
This series provides knobs which will enable users to
minimize memory consumption of mlx5 Functions (PF/VF/SF).
mlx5 exposes two new generic devlink params for EQ size
configuration and uses devlink generic param max_macs.
Patches summary:
- Patches-1-2 Provides I/O EQ size param which enables to save
up to 128KB.
- Patches-3-4 Provides event EQ size param which enables to save
up to 512KB.
- Patch-5 Clarify max_macs param.
- Patch-6 Provides max_macs param which enables to save up to 70KB
In total, this series can save up to 700KB per Function.
