# Goal of this package is to allow Termux to use on-device OpenCL drivers
|
||||
# without export LD_LIBRARY_PATH=/vendor/lib64
|
||||
|
||||
# Currently it copies libOpenCL.so from /vendor or /system and patch it
|
||||
# on the fly. Then ocl-icd detects it. This works for Mali.
|
||||
|
||||
# Adreno requires export var as its missing cl_khr_icd which ocl-icd needs.
|
||||
# But export var will replace ocl-icd altogether.
|
||||
|
||||
# List of libOpenCL.so drivers from different vendors:
|
||||
# GPU SONAME cl_khr_icd Supported
|

# Arm Mali libGLES_mali.so y y
|

# Qualcomm Adreno libOpenCL.so n n
