• GPU empty Kernel overhead
    Hi,                    I am observing GPU kernel is taking huge time when I am running an empty kernel. I am Using "Samsung Exynos Octa 5420 Board" which has Mali GPU. I have one kernel which is of work...
  • glMapBufferRange and glUnmapBuffer performance on the Mali-T880
    Hello all, I'm currently using glMapBufferRange to update a trippled buffered UBO in instanced rendering, but I'm noticing that calling glUnmapBuffer is taking ~0.5ms of CPU time, despite calling...
  • CL_MEM_USE_HOST_PTR overhead
    Hi, I would like to confirm whether CL_MEM_USE_HOST_PTR has extra overhead, such as memory copy, on Mali G72. According to ARM OpenCL Optimization Guide, using CL_MEM_USE_HOST_PTR is discouraged....
  • Overhead generated by calling clCreateBuffer
    Hi everyone, I'm using OpenCL on an Exynos 8890 Octacore CPU with ARM Mali-T880 MP12 GPU (Samsung S7 edge). And it is taking a high overhead when creating a buffer from the call clCreateBuffer. I...
  • MALI OpenCL: clEnqueueNDRangeKernel and clEnqueueTask has high API overhead
    Dear All, One of my use cases of ARM Mali graphics is running Video(HEVC) Decode Kernels. But, what we discover is that the OpenCL Kernel call APIs clEnqueueNDRangeKernel and clEnqueueTask overhead is...
