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 - Implicit sync / reservation objects - DRM sync objects - Power management suspend / resume - Render job submission - Compute job submission - META firmware processor - MIPS firmware processor - Basic GPU hang recovery Still to do: - Transfer job submission (needed for Vulkan) - No-op job submission (needed for Vulkan) - Support RISC-V firmware processor - GPU hang detection - Handling for running out of parameter buffer space - DVFS 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). 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've got several APIs left to implement and a bunch that are queued up. We've mainly been running the Sascha Willems 'triangle' example to verify that we've not regressed anything, along with the 'pipelines' example and a simple compute example. We've not yet done a full conformance run, so I don't have any numbers to share just yet. 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.
