5 years agonet/mlx5: add control of excessive memory pinning by kernel
Yongseok Koh [Mon, 1 Apr 2019 21:17:54 +0000 (14:17 -0700)]
net/mlx5: add control of excessive memory pinning by kernel

A new PMD parameter (mr_ext_memseg_en) is added to control extension of
memseg when creating a MR. It is enabled by default.

If enabled, mlx5_mr_create() tries to maximize the range of MR
registration so that the LKey lookup tables on datapath become smaller
and get the best performance. However, it may worsen memory utilization
because registered memory is pinned by kernel driver. Even if a page in
the extended chunk is freed, that doesn't become reusable until the
entire memory is freed and the MR is destroyed.

To make freed pages available immediately, this parameter has to be
turned off but it could drop performance.

   memory allocator.

b) UAR should be remapped for secondary processes. Currently, in order
