Used to be a staff member working on an x86 OS called CTOS. I realized if I implemented a couple of traps, we could run command-line DOS programs. So I did. And it worked. Dev tools, text processing, piped commands all worked.
It helped that the DOS executable format was the same as the CTOS format - because we had traded Bill Gates our linker (which produces executables) for his BASIC compiler.
I developed for windows before moving to linux. I was surprised to find that was no system call similar to windows WaitForMultipleObjects. Sure you can implement something similar using poll() or using condition variables. but WaitForMultipleObjects seems so much simpler and more versatile
A lot of that flexibility is what makes it hard to efficiently emulate (especially without kernel level support), but some of it seems too flexible to make sense as the default choice. How often does a video game really need a lock that can be shared between processes, and why should that lock type be the one that a game engine uses for almost all of its locks?
> How often does a video game really need a lock that can be shared between processes,
What do you mean? SRWLock (or the older CRITICAL_SECTION) cannot be shared between processes. A (Win32) Mutex can be shared between processes, but that's its entire purpose. So Windows does have different tools for different jobs.
In fact, it's really the other way round: on Linux, a futex also works across processes, but there is no equivalent in Windows. (Sadly, WaitOnAddress can only be used in a single process.)
How often does a video game really need a lock that can be shared between processes,
That seems hugely useful for interprocess communication and I can immediately think of reasons to use IPC in a game. Having a separate voice process for one.
The last time I asked the same question here, someone finally pointed out [1][2] a significant difference: wfmo can actually acquire semaphores in addition to waiting for them, which poll can't do in a non-racy way and efficient way. It can also do rendezvous synchronization (i.e. signal-and-wait).
I wonder what spanners Windows can throw into the works to slow them down at this point, or if they're so checked out of the Desktop market as they suckle down hard on that Azure teat, that they're more than happy to let Linux eat their lunch
You are not gonna get promoted slowing down Linux gaming at MS today, the thing they want is Netflix of gaming where the platform doesn’t matter but everyone’s paying them $20 a month
Microsoft/Xbox is in the process of losing the living room permanently in the next gen if you ask me.
I don't know what they could do spanner tossing wise to really screw w/ Linux gaming at this point that wouldn't just drive more frustrated customers off their platform.
That might make room for Apple to finally try. The AppleTV is already in a similar tier to modern consoles, as far as specs and benchmarks go. Most of what's missing is a first-party controller and a marketing push. Disk space is tight, too, I guess. Still, they're most of the way to having a horse in the race, if they want to.
I reckon a successful launch of the Steam box (or whatever they're calling it) with its enormous library could develop into something that really challenges what's left of Microsoft's piece of the console market (and threaten Sony a little, for that matter) though it's looking like the memory shortage is gonna kneecap that by forcing the price too high. Bad timing.
>The AppleTV is already in a similar tier to modern consoles, as far as specs and benchmarks go
What benchmarks are you talking about? CPU-wise the A15 Bionic just barely beats the Ryzen 3700X in single-core and gets absolutely destroyed in multi-core (Geekbench). As for the GPU, the Radeon RX 7600 (closest thing I can find to a "modern console") does >10x the TFLOPS in FP32.
The only reason why they look like they're "in a similar tier" in ported games is because the A15 Bionic is usually tested on 5-6" screens that can be upscaled from 360p without any measurable loss in visual quality, with a massive downgrade in model and texture quality for the same reason. The only modern console the Apple TV "may be" similar to is the Switch 1
Lock future game developers in to a corner forcing them only to produce compatible for WSL, Windows for Linux releases. Restricting the license of use on GNU/Linux.
I predict that ntsync will eventually evolve into full blown ntoskrnl.ko and there would be virtually no overhead on calling Windows API. You can almost call it a Linux Subsystem for Windows.
AMD. The final holdout, HDMI 2.1 support being blocked by the HDMI group, has been overcome w/ the HDMI group relenting and support is now landing in the kernel (expected in 7.2).
I sort of figured that HDMI stupidity was strategically a good thing as it sort of brought the dynamic of the HDMI consortium and VESA. specifically how they treat the end users, more to the public eye.
That is, more people being subtly pushed to using display port is not a bad thing.
I didn't follow this story much: how exactly did they get past the legal hurdles? Or there never actually were any actual hurdles, just sabre rattling?
Some people have TVs or displays that only use HDMI. I personally wouldn't recommend HDMI if DisplayPort is available, but if HDMI is your only option, then having it work properly will be important.
Unless you're on the absolute newest stuff with DisplayPort 2.1, HDMI 2.1 has more bandwidth. That'll be Nvidias 2000 through 4000 series. No DisplayPort 2.1 until the RTX 5000s.
And then monitors released during this time generally do the same too.
My monitor has 1 displayport and 2 hdmi and I have 2 computers I use with it. They can't share the displayport. All comparable monitors (last time I checked) have the same. So it'd be nice if both worked.
The cable length limitations are also a pain in the ass for not-uncommon A/V system configurations. 6' recommended max, and the best you might get working stably if the device and cable gods smile on you is 15'. 6' is the lower edge of acceptable for just about any A/V system setup (in practice it means your devices need to be within about a meter of the screen's port[s], which is pretty close) and even 15' is still too short to be useful for, say, a projector, or a "the A/V receiver or HDMI switch is over in that cabinet, the TV is on this wall across the room" situation.
AMD does a lot of work to ensure their support for Linux is first-class.
With the kernel now natively supporting their systems, you can expect good support.
It's earned them some good will over Nvidia
which has gotten better recently with the rise of AI, but still requires users to jump through a couple of hoops due to their attempts to protect their IP.
It is more than that, I really like openbsd as a desktop system. This is niche enough that I have zero expectation for any sort of support from the hardware vendors. However, because the amd drivers are opensource. Heroic people in the obsd dev community are able to make it work there. I don't strictly need a gaming gpu for my desktop work, but it is nice to have a setup I can boot linux on to play games with.
Heroic because the amdgpu driver is strangely huge, more code than the rest of the obsd kernel combined, It has something to do with gpu's having no isa stability and the generated code for each card present in the driver.
I built a Linux gaming PC a few years ago, running Bazzite.
AMD is much better. Nvidia has been improving but stuff "just works" with AMD because the kernel (amdgpu) and userspace (RADV) drivers are open source. Valve is a major RADV contributor too.
I don't feel like I'm missing out on anything with my 9070 XT. Performance is great.
Just anecdata, but I just got a Lenovo T16 with AMD. Graphics is just painless, everything works with no issues. My old system with an Nvidia card running the same O/S keeps running into weird issues. It mostly works, just needs attention and little tweaks and extra stuff sometimes.
For gaming and desktop use AMD is great, though for raytracing you'll need newer cards. If you want to run local AI models too then AMD is quite shaky, rocm only supports a few cards with each version and their software stack just isn't as polished as nvidia's.
End of 2024 I did exactly that. Ryzen and RADEON all the way. Rocking Fedora right now but was using Ubuntu for a bit. I have no reason to use Windows at all.
AMD for sure. Years ago for Linux NVIDIA was the sure winner. At the moment, AMD beats it out soundly on both cost and performance. ie, the same game running on either an NVIDIA or AMD GPU in Linux will generally run much better on the AMD GPU.
People say you will have less problems with AMD but I am using a Nvidia GPU for years now (on Cachyos and Pop OS) without issues. I'm using Steam and Proton pretty much exclusively though.
Which card and which drivers? I switched from Windows 10 to Xubuntu last year and have had endless issues with my Nvidia card (GTX 970). At the moment, I can't even use the desktop without annoying flickering & hard to diagnose / fix bugs.
Its an old card so I have no idea why I'm still struggling to get it to work. Is it perhaps because I'm using Xfce? I heard that Nvidia cards play better with Wayland although I haven't tested this myself.
Anything between 700 and 2000 series (inclusive) is in this "completely proprietary due to signed firmware but also not fully supported in Wayland" zone. You need to have at least 3000 series to have proprietary drivers with open kernel driver and good KMS/GBM/Wayland support.
> Nvidia on laptops? Insert the famous Linus Torvalds meme here
I have an RTX 5070 (whatever the laptop variant is) and it absolutely rocks with almost everything I throw at it, running Ubuntu+Steam+Proton. I no longer worry whether a Windows game is going to run, because almost all of them do with good performance.
AMDs are much better supported. There is life with NVIDIA GPUs too, I am on 4070Ti currently doing fine, but for new builds AMD is clearly a better choice with better drivers
In good faith, you can't really say "[x] is shit" if you don't have an usual setup; X11 is no longer the default on most distros. Even when I was also using it, it never crashed.
I don't know whether your GPU is older than mine or not but I have the RX 7700XTX. Maybe it had a software defect...
I only hope this eventually reaches enough coverage to support media production. It’s the last commercial area I care about. I’m entirely willing to pay for good work here (and have) but both major commercial desktop OSs are exhibiting significant warning signs of contempt for the users.
Headline says "Windows APIs are becoming Linux kernel features", but only provides two actual examples? It lists NTSYNC, and waiting on multiple events at once.
I remember when XDA was the home of Android homebrew hackers working on things like CyanogenMod. It's so strange to see it repurposed as the brand for the same quasi-correct tech article slop that gets parroted between all the big blogs.
Tom's Hardware is a bit before my time, but I remember it being well regarded. I've seen a lot of similar articles under that name lately. I wonder if they've undergone similar fates.
Same with all the bigger tech blogs from a decade ago. How-To Geek is completely overrun with the same sort of slop. Finally had to remove it from my RSS reader.
Oh look at that, XDA and HTG are both owned by Valnet:
If by "thousands of virus" you mean software shipped by default in Windows, then I agree with you. Everything feels so sluggish on Windows 11 compared to any Linux distribution even if you run it on an HDD... it's ridiculous.
“He who fights with Windows should see to it that he himself does not become Windows. And when you gaze long into ntoskrnl, ntoskrnl also gazes into you.”
Seriously, is it really a victory if you have to adopt the architecture of your sworn enemy?
To quote Linus Torvalds from 1997: "I don't try to be a threat to Microsoft, mainly because I don't really see MS as competition. Especially not Windows - the goals of Linux and Windows are simply so different."
He got less humble later on when momentum started building behind Linux. To quote Linus Torvalds from 2003: “Really, I'm not out to destroy Microsoft. That will just be a completely unintentional side effect.”
We are so far removed from 1997 that this statement means nothing.
> the goals of Linux and Windows are simply so different.
So different that Windows muscle memory works on most main stream Linux UI's, Many (most?) Steam games run on Linux, and now we have Windows in the Linux kernel.
Does Windows muscle memory work? The vast majority of shortcuts are completely different for the casual user, and for the power user, there's no regedit or control panel and other such things.
Be that as it may, it means that the muscle memory (or more accurately, the mental model of the system) is gone. I've long held the belief that power users or knows-enough-to-be-dangerous users have a harder time switching for that exact reason.
A control panel (or cross-distro YaST) would be very welcome in the ecosystem I think.
> muscle memory (or more accurately, the mental model of the system)
That's not "more accurately", that's just a completely different thing. When I'm on Mac, my muscle memory is thrown off. I'll be typing and my ctrl+s, alt+tab, win+4, ctrl+left* all cause wildly unpredictable (to me) things. I'm currently using Linux, and all of those things work how I expect (with a tiny asterisk on win+#). When I want a control panel, I press the windows button on my keyboard to open something functionally equivalent to the start menu, and open System Settings to get something functionally equivalent to the control panel.
I have no doubt that I could learn the deep differences between Windows and Mac over time, but the initial muscle memory causes me stress before I get to that point. When I switch to Linux I don't have that stress, and so I've been comfortably learning those differences.

WSL 1.0 was doing something like that. Doing syscall translation in real time. Eventually edge cases forced them to abandon that architecture and now it's just a VM.
What is the purpose of achieving victory? Is it to produce the software that works better or is it to stick your fingers in your ears and lalala the loudest?
Not really, in the drunken happiness to have games, Linux users keep forgetting those are games developed on game studios that the only place there are GNU/Linux installations running are their MMO servers.
It is no different from arguing how Linux is getting better GameCube games with Dolphin.
Also Valve is only as good as its current management is still around, eventually like any other company time will pass, and new warm bodies will take other decisions.

I have a dumb-ish Samsung Hotel TV / commercial TV at home. It has DP.
And then monitors released during this time generally do the same too.
HDMI goes 25'+, no problem.
Don't all USB-C video outputs use DP alt mode too, with an HDMI adapter at the end? And they can do HDR.
and displayport 2.0, since 2019, has supported all the same variations (hdr10+, dolby vision) that HDMI does
