In questa guida spiegheremo come installare e configurare Da Vinci Resolve 17 su Fedora 34.
Innanzi tutto andiamo a scaricare i driver ROCM 2.5 di AMD.
Ora creiamo il file repo locale /etc/yum.repos.d/rocm.repo contenente le seguenti righe :
[ROCm]
name=ROCm
baseurl=http://repo.radeon.com/rocm/yum/2.5/
enabled=1
gpgcheck=0
E ora installiamo i pacchetti necessari per far funzionare OpenCL:
Se hai una scheda VEGA o più recente ( testato su AMD Ryzen 5 3500U with Radeon Vega 8 Mobile )
# Install prereqs for hcc
sudo dnf install npth-devel hsa-ext-rocr-dev rocm-utils
# force hcc installation
sudo dnf download hcc
sudo rpm -ifvh hcc-1.3.19212-Linux.rpm --nodeps
Installiamo i seguenti pacchetti: ( il risultato vi darà che è stato installato già precedentemente )
sudo dnf install rocm-clang-ocl rocm-opencl rocm-opencl-devel rocm-utils
Diamo il seguente comando:
/usr/bin/rocminfo
Output
ROCk module is loaded
Able to open /dev/kfd read-write
