From 32660f9ff9608dc595f4bdf3944a3ceb37d67a79 Mon Sep 17 00:00:00 2001 From: Davide Grohmann Date: Wed, 27 Apr 2022 16:49:07 +0200 Subject: Use ids for identifying messages sent to EthosU firmware Avoid to use pointers to kernel memory as identify messages, prior this change, if memory is reused that can lead to unexpected conflicts. Remove ref counting from capabilities and network_info since memory is freed in only one place. Finally, extract the capabilities code in its own files.
