Mesa, opencl, rusticl
Форум — General
GPU - AMD Radeon RX 6700 XT.
Собираю mesa-24.1.1 с флагом opencl, устанавливаю глобально переменную RUSTICL_ENABLE=radeonsi.
Ни Libreoffice, ни SVP4 не работают с opencl, не видят его.

ICD loader properties
ICD loader Name Khronos OpenCL ICD Loader
ICD loader Vendor Khronos Group
ICD loader Version 3.0.6
ICD loader Profile OpenCL 3.0
На форуме SVP4 подсказали, что это из-за «Device Profile» = «EMBEDDED_PROFILE», в то время как программы ожидают «FULL_PROFILE».
Если поставить rocm-opencl-runtime-5.5.1, там «Device Profile» = «FULL_PROFILE» и все работает.
Что такое этот «Device Profile»? От чего он зависит и как его поменять?
