Developing our own KMD is not really an option
Why not? Fully open-source Windows GPU drivers would be great. Incidentally, this sort of "glue code" is probably something LLM assistance could help greatly with much of the grunt work.
(E.g. there is already a generic framebuffer driver for Win3x/9x: https://news.ycombinator.com/item?id=47646363 https://news.ycombinator.com/item?id=47646363 but one of the ideas I have --- which anyone else with the time is more than welcome to attempt --- is to port the existing open-source Linux drivers for AMD/NVIDIA/Intel to early Windows versions that never even had closed-source drivers available, giving them full 2D/3D acceleration. Theoretically, something as crazy as CUDA on Windows 95 is possible, and perhaps some vibecoding can turn that into reality. After all, as I write this comment, https://news.ycombinator.com/item?id=49089814 https://news.ycombinator.com/item?id=49089814 is on the main page.)
- LoganDark 2mo agoYou can't really develop a kernel-mode driver nowadays without being an incredibly large OEM. Otherwise, you won't be accepted by any anti-cheat.
- Maakuth 2mo agoAn anti-cheat app would probably be quite surprised to find it's running on Windows 95 anyway.
- ChocolateGod 2mo agoWireguard...
- grim_io 2mo agoWireguard is blessed by Microsoft, who sign their drivers.
- not_a9 2mo agoSandboxie/WinFSP/KVM guest drivers for Windows are open source too I’m sure there are more open source examples. A newer one is https://github.com/namazso/PawnIO/tree/master https://github.com/namazso/PawnIO/tree/master I guess?
- Almondsetat 2mo agoSo we should throw away the possibility entirely just because of a few videogames? That doesn't sound reasonable at all, considering most videogames don't have anti cheats and GPUs can be used for way more stuff than playing.
- userbinator 2mo agoExactly, being able to use a local LLM or other generative AI on a machine running Win95 would itself be sufficiently entertaining.
- not_a9 2mo agoIf anti-cheats actively whitelisted drivers playing competitive video games would be impossible for people using any rarer HW/utilities. Vulnerable drivers are generally blacklisted when found. Getting your driver signed seems like a pain these days, yeah
- nananana9 2mo agoI'm inclined to believe this is exactly what happens, given that both Bluetooth and my printer stopped working the last time I tried playing a Riot game. Also got a BSOD in vgk.sys, and it left a bunch of junk in my EFI partition after I uninstalled it. Fun times.
- LoganDark 2mo agoMaybe drivers are treated differently, but I remember having to update Windows 11 to play ARC Raiders because my specific version was old enough that system files did not pass their whitelist check. It told me which system file failed the check - I don't remember which it was exactly, but it definitely wasn't one that'd ever been modified, just one that wasn't recent enough it seems, at least going off of how updating fixed it.
- inigyou 2mo agoYes this is how they work. You use a mainstream GPU or no game for you!
- not_a9 2mo agoThrow a lawn dart at the contents of https://vx-underground.org/Archive/Driver%20Collection/Bulk%20Downloads https://vx-underground.org/Archive/Driver%20Collection/Bulk%... all drivers download, load the resulting driver and try to get into Fortnite or something. It'll probably get in fine assuming driver isn't Unknowncheats superstar already
- ZiiS 2mo agoFor Windows 3x/9x the common term was VxD, KMD strongly implies an NT derived OS.
- pjmlp 2mo agoNot only that, Windows NT driver model already changed at least twice since Windows XP, on Vista and Windows 10.
- pjmlp 2mo agoCertainly OpenGL and DirectX acceleration was a thing in Windows 9x, kind of missing the point.
- nananana9 2mo agoVideocards of the era only did exclusive fullscreen - you could not for example use OpenGL to render your windowed application's UI, that was all software.
- pjmlp 2mo agoMy graduation thesis was porting a particle visualisation engine from NeXTSTEP into Windows 9x.
- kg 2mo agoI don't think this is true? I remember successfully using OpenGL and Direct3D acceleration in windowed mode on 9x devices. Are you thinking of the add-on 3D accelerator cards that did VGA pass-through from your 2D accelerator? It might've been true for them...
- MayeulC 2mo agoI almost wrote the same comment — the first part, anyways. In theory, it should be feasible to provide a "shim" to bridge the API gap between Linux and Windows internal APIs. The catch here is that Linux is a moving target. AMDGPU (the Linux kernel module) has its roots in a shared Linux/Windows codebase from AMD, so hopefully it didn't get _too_ tightly integrated (I know some parts got integrated, IIRC it used to ship its own i2c driver).
- AshamedCaptain 2mo agoI am quite sure AMD is already using a fork of the Linux amdgpu KMD for their proprietary driver on Windows (which in part explains why a project like this can even be done) Porting Linux drivers to anywhere is generally hard. It either makes your kernel very Linux-like (and lots of manpower to translate the abstractions), or forces you to put Linux on it. There are bazillions of projects to put recent Intel drivers on 9x and none suceeded, for example. Plus my recent observation that for Haiku it was easier to port the out-of-tree nvidia driver and fork Mesa, than it was to port the Linux amdgpu one.
- atq2119 2mo agoIn order to have a useful Windows desktop, you need a DX12 driver. So, in order to write their own KMD, they'd either have to also write their own DX12 driver, which they probably have no interest in, or reverse engineer the existing AMD KMD interface to the point where they can reimplement it basically completely so that AMD's proprietary DX12 driver runs on it. I doubt they're saying it's impossible, it's more of a pick your battles situation.
- happymellon 2mo ago> in order to write their own KMD, they'd either have to also write their own DX12 driver You mean Vulkan driver. We can run DX12 on Vulkan.
- atq2119 2mo agoDo you mean on Linux in a Wine/Proton context? That's different, so yes, I did mean DX12 driver. Again, not impossible, just picking your battles.
