Some A3xx and all A4xx Adreno GPUs do not have GMEM inside the GPU core and must use the On Chip MEMory (OCMEM) in order to be functional. There's a separate interconnect path that needs to be setup to OCMEM. This patch series adds support for that path, and sets the votes for the two interconnect paths to the highest speed for a3xx and a4xx-based platforms. Changes since v1: - Don't rename icc_path to gfx_mem_icc_path. Leave existing variable named as is and add comment to declaration in struct msm_gpu.
