rust: drm: Introduce the Tyr driver for Arm Mali GPUs
Add a Rust driver for ARM Mali CSF-based GPUs. It is a port of Panthor and therefore exposes Panthor's uAPI and name to userspace, and the product of a joint effort between Collabora, Arm and Google engineers.
The aim is to incrementally develop Tyr with the abstractions that are currently available until it is consider to be in parity with Panthor feature-wise.
The development of Tyr itself started in January, after a few failed attempts of converting Panthor piecewise through a mix of Rust and C code. There is a downstream branch that's much further ahead in terms of capabilities than this initial patch.
The downstream code is capable of booting the MCU, doing sync VM_BINDS through the work-in-progress GPUVM abstraction and also doing (trivial) submits through Asahi's drm_scheduler and dma_fence abstractions. So basically, most of what one would expect a modern GPU driver to do, except for power management and some other very important adjacent pieces. It is not at the point where submits can correctly deal with dependencies, or at the point where it can rotate access to the GPU hardware fairly through a software scheduler, but that is simply a matter of writing more code.
This first patch, however, only implements a subset of the current features available downstream, as the rest is not implementable without pulling in even more abstractions. In particular, a lot of things depend on properly mapping memory on a given VA range, which itself depends on the GPUVM abstraction that is currently work-in-progress. For this reason, we still cannot boot the MCU and thus, cannot do much for the moment.
This constitutes a change in the overall strategy that we have been using to develop Tyr so far. By submitting small parts of the driver upstream iteratively, we aim to:
a) evolve together with Nova and rvkms, hopefully reducing regressions due to upstream changes (that may break us because we were not there, in the first place)
b) prove any work-in-progress abstractions by having them run on a real driver and hardware and,
c) provide a reason to work on and review said abstractions by providing a user, which would be tyr itself.
Despite its limited feature-set, we offer IGT tests. It is only tested on the rk3588, so any other SoC is probably not going to work at all for now.
The skeleton is basically taken from Nova and also rust_platform_driver.rs.
Lastly, the name "Tyr" is inspired by Norse mythology, reflecting ARM's tradition of naming their GPUs after Nordic mythological figures and places.
