Vista's Graphics To Be Moved Out of the Kernel 555

Posted by Zonk from the just-like-in-the-constitution dept.
Tiberius_Fel writes "TechWorld is running an article saying that Vista's graphics will not be in the kernel. The goal is obviously to improve reliability, alongside the plan to make most drivers run in user mode." From the article: "The shift of the UI into user mode also helps to make the UI hardware independent - and has already allowed Microsoft to release beta code of the UI to provide developers with early experience. IT also helps make it less vulnerable to kernel mode malware that could take the system down or steal data. In broader terms, this makes Windows far more like Linux and Unix - and even the MacOS - where the graphics subsystem is a separate component, rather than being hard-wired into the OS kernel."

    So this is like cell division. The bloat of Windows divides into the Kernel and UI pools.

    Taking this article into account [slashdot.org], it seems clear why the massive graphics card requirement. However, if this much is being pulled from the Kernel, then why still such a massive minimum RAM?

        It's funny. Microsoft already did this with printer drivers. Windows NT 3.51 lived in userspace. In Windows NT 4 they moved into the kernel. In 2000, they moved back into userspace, but with a completely different architecture from 3.51. Windows Server 2003 still supports the NT4 model of kernel mode printer graphics drivers but that might change with Vista.

          I don't know about the printer drivers, but for the video, they claimed moving to kernel space made them faster (and did seem to), unfortunately it introduced an unenforced requirement that video drivers be fully debugged, which due to the nature of the business they never were. A once rock stable machine on 3.51 that could not be made stable on 4.00 without switching from ATI to Nvidia video cards is what first gave me doubts about whether I wanted to continue running Windows at home (or ATI video cards for that matter).

          The speed boost just wasn't worth it, in the same way that the functionality of run-on-load macros in Word documents aren't worth the trouble they cause. Maybe this is a sign that the true tech types are gaining influence over the marketing types at the company (but somehow I doubt that). For the sake of those still running Windows I hope they take all non-essentials out of kernel space and shoot for stability over speed or features.

            Don't confuse moving the Windows GUI to user space with moving video drivers to user space. The two are not one in the same. Even in Linux, most of the video driver bits live in the kernel. Same in Mac OS X. I'm sure the same will be true in Vista.

            Because of the nature of video, it would be impractical for video drivers to live anywhere BUT in the kernel. (See also: "microkernel".) Neither Linux nor Mac OS X puts video drivers in user space. Doing so would not be a bright idea. (I would also note that Linux and Mac OS X seem to be quite stable with ATI driver bits in their kernels.... :-)

            Drivers should be in the kernel if A. at least one of their primary clients exists in the kernel, e.g. disk controller drivers, B. they service a large number of clients directly (e.g. /dev/random), C. real-time performance is critical to the correct operation of the device (e.g. audio/video).

            Historically, video cards typically only had one client at a time. These days, the windowing system (WindowServer in Mac OS X, X11 in Linux, the Windows GUI layer) is usually the primary client, with the OS kernel being a secondary client (command-line console, panic text, boot console, etc.) Further, the graphics hardware can also be directly driven by an application for things like full-screen games. In Mac OS X, the graphics hardware is also often used for other tasks, e.g. with CoreImage. Graphics cards also depend on direct access to hardware interrupts for performance to be adequate. Moving the drivers into user space would make adequate performance for these sorts of tasks nearly impossible.

            Printers are the other extreme. They don't have their own hardware interrupts like with PCI devices, so if you're depending entirely on a faked software interrupt, the driver might as well be in user space. A printer will still print correct copy if the data arrives more slowly (up to a point, anyway). They only serve a single client (a local print spool of some sort) and cannot do more than one thing at the same time. Thus, printer drivers make no sense in the kernel.

Most of the admins were running the fanciest 3D CPU intensive screensavers they could find. When anyone would complain about performance they would go to the server, check task manager and come back with: "well it's only running at 20%". Finally someone thought to check the numbers remotely and discovered that the screensaver was by far the biggest hog. I don't think most Windows users, even the "pros" realize how much resource is involved in something as simple as moving the mouse, moving a window around or resizing it.

      Ah, yes. Just what we all want. Command-line administration of Active Directory and Exchange.

      Windows Server 2003's GUI overhead is extremely small in comparison to the other tasks it's performing. Besides, it's not a matter of being "scared" of a CLI, in fact pretty much all the Windows sysadmins I know (including myself) use the Windows command line on a regular basis. Believe it or not, but a GUI really can give a boost to speed and efficiency when it comes to server management, regardless of what the zealots here might say.

      It seems to me that moving graphical operations to userland would make them more hackable rather than more secure. One userland app could more easily preempt another userland app, and something kernel-loaded could be used to trick a userland app into ignoring copy protection.

      Also, I believe that a userland application might be a little easier to decipher, and you wouldn't need to know as much about the hidden tricks that the windows kernel might be using (or you could intercept the various calls).

    to do that, they had to rip out the entire terminal server subsystem,

      No. This is not true and represents a misunderstandings about how the Win32 API is implemented in NT. For legacy reasons many windows programs would use the GUI APIs for internal IPC (why oh why wasn't LPC exposed to userspace though?). Anyhow, this mean that the Win32 subsystem server (CSRSS) ran both the GUI and the rest of Win32.

      So a crash in the GUI (running inside the context of CSRSS) would result in all Win32 apps being shutdown. Perhaps the file services (part of SRV.SYS) would remain in the event of a GUI crash but any applications running under Win32 context would be lost. That was the reasoning that allowed M$ to temper DaveC's fears and move the GUI to WIN32K.SYS in NT 4.0.

      I'm not defending the approach. I disagree with the GUI-in-kernelspace idea as well. I'm merely pointing out the way things went in terms of history. Ideally the GUI services and kernel services would be separate APIs in Win32 so that server and console applications could live without the GUI. But compatability was a major goal...

      Personally, I would love to ditch the Windows GUI but keep the NT kernel. The NT kernel (despite the typical conditioned response of the average slashdotter) is quite good in many areas. The GUI API of Windows was inferior to OS/2's Presentation Manager (the big change being client area -> client window). Too bad OS/2 PM can't be run under the NT kernel. Oh well, it almost happened...

      That's funny - the Mac zealots I talk to are going around complaining about Starbuck's supposedly inefficient "vanilla latte foaming technique".

    In other words OpenGl will suck, because DirectX will have direct access to the kernel while OpenGl (and other graphics APIs) will be delayed by inumerous error checks by the interface.

    Repeat after me, the GDI is not part of the kernel, it simply runs in kernel space (AKA higher privledge). Unlike, linux where everything in kernel space is basically compiled against the kernel headers and is bound to a kernel version, NT has both user and kernel mode API's. To say the graphics system is hard wired to the kernel is like saying my hello-world program is part of libc. Moving it back to userspace should be about as hard as it was back in the NT 3.51 timeframe to move it into kernel space.

    Despite the general feeling here, i'm starting to be really interested in vista...
    It seems they have fixed almost everything that was wrong with windows. I mean:
    • Explorer rewriten from scratch. This was long, long overdue and that alone would make me interested in Vista. Explorer makes windows looks buggy sometimes but it's only explorer.exe which sucks...
    • Monad. A real shell, which could possibly be much more powerfull than say bash+ standard Unix commands (or cygwin...)
    • They're moving the graphics subsystems and all the bloody drivers in userland. That means it will be dead stable, period. 2000 and Xp are already at least as stable as Linux, and maybe more. After that i'm sorry but Linux will compare the same way to Windows that Win95 did to Linux...
    • A hardware accelerated graphic system, ala Quartz. It should rock even if They'll probably make it look and act totally stupid out of the box, overusing their new power...

    And people complain that there is nothing new in Vista, phew... I mean if they manage to do all those things, and do them the right way like they seem to be decided to (for once...) it will be damn worth a new release...
    And no, i'm not a microsoft fanboy, i've been using Linux since 97 and I really like it where it shines. But if you have even a little objectivity you can't say the stuff they're putting here is not interesting...

  • Vista DirectX OpenGL Wrapper (Score:5, Informative)

    Wrappers for other graphics protocols have been around for a long time. You can still get Glide Wrappers for games that specifically require a 3Dfx Interactive Voodoo graphics card. Most of the newest wrappers work great. eVoodoo for instance is one of the best.

    What wrappers do, in "Windows", is take the function calls ment for Glide (or whatever graphics subsystem the program needs) and translates them into function calls that DirectX can understand. I've heard of Glide wrappers for Linux that translates into OpenGL.

    Anyway, DirectX in Vista will have something like a wrapper for OpenGL since there will not be any actual OpenGL drivers in the OS. This could be good or bad but the move does make sense. Instead of having two separate graphics subsystems in Vista they are narrowing it down to just one and keeping the ability to use programs that requires OpenGL. Most game developers have left OpenGL far behind anyway including Id Software a company that used OpenGL almost exclusively for years until Doom 3 and Quake 4 arrived which use DirectX. It wouldn't be too hard to add in OpenGL Optimization into the wrapper code so programs that use OpenGL won't suffer a performance hit. I cna also understand why Vista will need high graphics and memory requirements. The whole reason why the GUI was put into the kernel for NT 4.0 was for improved speed, but at the loss of stability. Taking it out again will improve stability, something that Windows needs badly. Todays faster CPUs and graphics card GPUs shouldn't really have a problem with Vista. Builtin video on motherboards usually aren't that good, but this move might convince manufaturers to start offering builtin video that is much better quality or switch to using standard video cards instead which is what they should have been doing in the first place.

    Yeah, running graphics drivers in kernel space is just plain ugly... Luckily for us Linux users, we can get full graphics acceleration by running the "userspace" NVIDIA kernel module ;-) Certainly increases stability!

    is because enough high level graphics functionality is moving into and being required of the graphics hardware now that the performance loss on most machines will be acceptable. i.e. it is heavily tied to the hardware requirements Vista has added. If they couldn't do it without losing significant performance, they wouldn't. Performance sells before stability.
