When you are doing a project or have an interest in something you haven't thought of everything. I have talked to creators before about their projects ending up here. This initially seemed like a problem too intractable to solve, but Sven took on the challenge and now has a patch series that makes Linux’s IOMMU support layer play nicely with hardware that has an IOMMU page size larger than the kernel page size! It’s not perfect, as it can’t support a select few corner case drivers (that do things that are fundamentally impossible to support in this situation), but it works well and will support everything we need to make 4K kernels viable.įor anybody who wants to read the whole thing: Linux can’t really mix page sizes like that and likely never will be able to, so we’re left with a conundrum: running a 16K kernel makes compatibility with older userspace difficult (chiefly Android and x86 emulation), plus distros don’t usually ship 16K kernels while running a 4K kernel runs into a major mismatch with the DART. These chips have 4K support chiefly to make Rosetta work on macOS, but macOS itself always runs with 16K pages – only Rosetta apps end up in 4K mode. Its DART IOMMU hardware only supports 16K pages. > IOMMU 4K patches (in review): The M1 is peculiar in that, although it supports OSes that use either 16K or 4K pages, it really is designed for 16K systems. Here the relevant text about 16k page size kernels: Apparently these people are insanely petty and gifted developers. I had no idea until I saw these comments.
