From 3c15ddb97c77f34ba009910becd5921f169770a2 Mon Sep 17 00:00:00 2001 From: Victor Chong Date: Wed, 11 Apr 2018 10:19:53 +0100 Subject: [PATCH] tee: optee: log message if dynamic shm is enabled When dynamic shared memory support is enabled in the OP-TEE Trusted OS, it doesn't mean that the driver supports it, which can confuse users during debugging. Log a message when dynamic shared memory is enabled in the driver, to let users know for sure.
