From: Leon Romanovsky <leonro@xxxxxxxxxxxx> Hi, Libmlx5 needs real knowledge of BlueFlame size to properly set data path to leverage performance advantages of BF. However such advantage is visible in systems which use WC memory. Unfortunately, user space applications (and libmlx5) can't know if memory is WC or not, so we rely on in-kernel test to set BF dynamically.
