[PATCH v3 00/17] Imagination Technologies PowerVR DRM driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

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

Job stream formats are documented at:
https://gitlab.freedesktop.org/mesa/mesa/-/blob/73fe6db819d951c02ce57eefcbd9b31b85900f33/src/imagination/csbgen/rogue_kmd_stream.xml

The Vulkan driver is progressing towards Vulkan 1.0. We're code complete, and
are working towards passing conformance. The current combination of this kernel
driver with the Mesa Vulkan driver achieves 71.8% conformance.

The code in this patch series, along with some of its history, can also be found here:
