From b40d9dbc0b69b8f18cd19e687773e84b84c3c736 Mon Sep 17 00:00:00 2001 From: Naushir Patuck Date: Thu, 6 Jun 2024 11:15:11 +0100 Subject: utils: raspberrypi: ctt: Add option to convert between vc4/pisp targets This change adds functionality to the convert_tuning.py script to convert between vc4 and pisp target tuning files. The conversion is done on a best effort basis, and should provide functional tuning files. However, a full tuning for the target platform is always preferred.
