From 5d6d7e443deab3ed2272940499e246629c737377 Mon Sep 17 00:00:00 2001 From: Marcin Smoczynski Date: Tue, 4 Feb 2020 14:12:53 +0100 Subject: [PATCH] security: add CPU crypto action type Introduce CPU crypto action type allowing to differentiate between regular async 'none security' and synchronous, CPU crypto accelerated sessions. This mode is similar to ACTION_TYPE_NONE but crypto processing is performed synchronously on a CPU.
