A number of GPUs use a standard Arm SMMU instead of an IOMMU already. The problem with those GPUs in general is driver issues, the hardware is fine.

- matheusmoreira 3y agoIs the GPU driver closed source?

Perhaps some GPUs do, but many (most?) don't including the Mali-G710 in this article that's currently shipping in the Pixel 8. > The problem with those GPUs in general is driver issues, the hardware is fine. Exactly. I want them to stop writing bespoke kernel code manually fiddling with some custom page table format that gives physical memory read/write primitives when they get it wrong.
