Will resend. It appears it was sent, but may have been dropped due to size? It's at https://lists.freedesktop.org/archives/dri-devel/2023-August/418802.html. Apologies for the confusion. Sarah
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 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 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/f8d2b42ae65c2f16f36a43e0ae39d288431e4263/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 (powervr-mesa-next branch) achieves 88.3% conformance. The code in this patch series, along with some of its history, can also be found here: https://gitlab.freedesktop.org/frankbinns/powervr/-/tree/powervr-next This patch series has dependencies on a number of patches not yet merged.
