This patch series adds the initial DRM driver for Imagination Technologies PowerVR GPUs, starting with those based on our Rogue architecture. It's worth pointing out that this is a new driver, written from the ground up, rather than a refactored version of our existing downstream driver (pvrsrvkm). This new DRM driver supports: - GEM shmem allocations - dma-buf / PRIME - Per-context userspace managed virtual address space - DRM sync objects (binary and timeline) - Power management suspend / resume - GPU job submission (geometry, fragment, compute, transfer) - META firmware processor - MIPS firmware processor - GPU hang detection and recovery Currently our main focus is on the AXE-1-16M GPU. Testing so far has been done using a TI SK-AM62 board (AXE-1-16M GPU). Firmware for the AXE-1-16M can be found here: https://gitlab.freedesktop.org/frankbinns/linux-firmware/-/tree/powervr
And what about another PowerVR (rogue-based) GPU? There are a lot of different models of rogue GPU in existed SoCs. New driver uses v3 firmware, but vendors uses v1/v2 firmwares. Who will provide firmware/source code v3 for all the others models?
