From 3a924ee250ade392643656eeef88f380bf519c2e Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Thu, 3 Oct 2019 17:20:36 +0200 Subject: test: ipa: Add test for the IPA Interface Implement a basic test for IPA Interface using the VIMC dummy IPA module. The test implements an out-of-band feedback channel between the test and the dummy IPA module to verify the success of the IPA interactions. Test the only available operation defined by the IPA interface by receiving a confirmation code on the fifo communication channel.
