This driver was tested using the drm/imagination GPU driver. It was able to successfully power on the GPU, by passing a command through mailbox from E910 core to E902 that's responsible for powering up the GPU. The GPU driver was able to read the BVNC version from control registers, which confirms it was successfully powered on. [ 33.957467] powervr ffef400000.gpu: [drm] loaded firmware powervr/rogue_36.52.104.182_v1.fw [ 33.966008] powervr ffef400000.gpu: [drm] FW version v1.0 (build 6621747 OS) [ 38.978542] powervr ffef400000.gpu: [drm] *ERROR* Firmware failed to boot Though the driver still fails to boot the firmware, the mailbox driver works when used with the not-yet-upstreamed firmware AON driver. There is ongoing work to get the BXM-4-64 supported with the drm/imagination driver [1], though it's not completed yet. This work is based on the driver from the vendor kernel [2].
