Because at the moment, my laptop (with Mesa and 18.04) can only use OpenCL 1.1 (that is, it can not be used for Cltorch, mix cycles, etc.). I decided to install the RocM driver and tried to use the upstream driver and others, but it appears right after a reboot using the Mesa driver I just updated the app.
I first tried the drivers upstream because I have an APU carrizo
