From e8b26b2135dedc0284490bfeac06dfc4418d0105 Mon Sep 17 00:00:00 2001 From: Artemy Kovalyov Date: Tue, 19 Mar 2019 11:24:38 +0200 Subject: [PATCH] net/mlx5: Decrease default mr cache size Delete initialization of high order entries in mr cache to decrease initial memory footprint. When required, the administrator can populate the entries with memory keys via the /sys interface. This approach is very helpful to significantly reduce the per HW function memory footprint in virtualization environments such as SRIOV.
