This patch 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 (device node open) 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 - Basic GPU hang recovery Still to do: - Document format of job streams and static context state - GPU hang detection - Handling for running out of parameter buffer space (this has made progress since RFC v1, but is still incomplete) Currently our main focus is on our GX6250, AXE-1-16M and BXS-4-64 GPUs. Testing so far has been done using an Acer Chromebook R13 (GX6250 GPU) and a TI SK-AM62 board (AXE-1-16M GPU). An example SK-AM62 development board can be obtained here: https://beagleboard.org/play Firmware for the GX6250 and AXE-1-16M can be found here: https://gitlab.freedesktop.org/frankbinns/linux-firmware/-/tree/powervr A Vulkan driver that works with our downstream kernel driver has already been merged into Mesa [1][2]. Support for this new DRM driver is being maintained in a draft merge request [3], with the branch located here: https://gitlab.freedesktop.org/frankbinns/mesa/-/tree/powervr-winsys The Vulkan driver is progressing towards Vulkan 1.0. We're code complete, and are working towards passing conformance. This is a work in progress, so we're not sharing numbers just yet. We are still looking at whether any functionality can be replaced with DRM common code. We are still considering drm_sched and the GPU VA manager. The code in this patch, along with some of its history, can also be found here: https://gitlab.freedesktop.org/frankbinns/powervr/-/tree/powervr-next Sending this out now as it felt like a good point to get some feedback.
