zircon kernel reddit

zircon kernel reddit

I created AI to unlock all the trophies in the android game ZigZag. What else would you want to do with sel4 but ship it unchanged? But snakes are of the devil and camels are merely rude. [–]naasking -2 points-1 points0 points 2 years ago (0 children). [–]barsoap 1 point2 points3 points 2 years ago (0 children). Linux. They don't need to combine anything with the kernel, that's point of microkernels. it's just an obscure code blob that approximately acts somewhat like a scheduler. Release dahliaOS Linux-Based build 201004 5th of October, 2020. Archived. [–]tending 6 points7 points8 points 2 years ago (4 children). Almost nobody adapts as naturally to technology as I do. While it is still far from being finished or stable, it is still a good start. Do you have something funny to share with fellow programmers? There used to be a debate between folks about whether monolithic kernels or microkernels were the superior … Linux doesn't go nearly that far. TinyOS. [–]exorxor 0 points1 point2 points 2 years ago (1 child). Even for windows, there are a lot of legal questions about making GPLed drivers. You must be fun to work with. There's absolutely no valid technical or business reason. The actual context switching code is architecture dependent and can be found: https://github.com/fuchsia-mirror/zircon/blob/master/kernel/arch/arm64/asm.S (for arm64), https://github.com/fuchsia-mirror/zircon/blob/master/kernel/arch/x86/asm.S (for x86_64), [–]myusernameisokay 38 points39 points40 points 2 years ago (3 children). Fuchsia is a foundation for developers to create long-lasting products and experiences across a broad range of devices. The coming era of OS kernel modularity # computerscience # operatingsystems # linux # fuchsia. This is either stupidity or malice. [–]aejt 2 points3 points4 points 2 years ago (0 children). [+]barsoap comment score below threshold-25 points-24 points-23 points 2 years ago (23 children). But, yeah, whatever. I know the big problem of microkernels is the IPC overhead still present even if reduced in new generations as the microkernels belonging to L4 family. Ignoring the essence and bitching about the superficial. The difference is that with sel4, much more is in user-mode so you can have less GPL code overall (if you care about taht). They would be wrong, but that is most likely what would happen. [–]tending 0 points1 point2 points 2 years ago (1 child). Fuchsia development is moving into a new phase of more public contributions. [–]experiencednowhack 9 points10 points11 points 2 years ago (0 children), This chapter would be an excellent reference (there are chapters before it in OSTEP if you're entirely new to schedulers) http://pages.cs.wisc.edu/~remzi/OSTEP/cpu-sched-mlfq.pdf, [–]roffLOL 50 points51 points52 points 2 years ago (0 children). What's the problem, too hard to attack for your NSA overlords? [–]barsoap 0 points1 point2 points 2 years ago* (2 children). Drivers are in user space with Zircon. Which is utter bunk, because their kernel doesn't derive from random userspace programs. Also gotta love github coloring functions and variables the same color. Zircon microkernel is the kernel adopted in Google's new OS Fuchsia. Some variation on O(n) is what older Unices used and Linux used a long time ago. They're just another process, and no OS ever forced a license upon processes running in userspace. In the past few months, Fuchsia’s Zircon kernel has picked up support for a handful of new devices, including two codenamed Google projects, each expanding the reach of what Fuchsia will run on. If it were easier to untangle then it would be interesting to try and start a porting project to Zircon from another OS, in the same vein as Debian/kFreeBSD or Guix/Hurd. Yes, those optimizations were very difficult to prove, but that also means it is a good topic for a paper... Read their papers for details. [–]exorxor 15 points16 points17 points 2 years ago (18 children), https://sel4.systems/Info/GettingStarted/license.pml, [+]barsoap comment score below threshold-17 points-16 points-15 points 2 years ago (17 children). Swapping out a component and improving upon it will still put us back in the original territory. It's Google's kernel, so they probably know why they're doing it, but they didn't divulge anything yet. Essentially, the code change allows AMD-powered Chromebooks on the ‘Grunt’ board to boot Fuchsia’s Zircon kernel. [–]IshKebab 2 points3 points4 points 2 years ago (2 children). In that case it could still be a performance thing. [+]JavierTheNormal comment score below threshold-49 points-48 points-47 points 2 years ago (10 children). [–]XANi_ 12 points13 points14 points 2 years ago (1 child). Google doesn't control Linux. It picks the thread at the root of a red-black tree, which has O(log n) worst case for balancing. Just because the goal is to make a general purpose OS, I'm very curious regarding Zircon performance especially when compared to the ones of traditional monolithic kernels i.e. 1) What are the performance of Zircon compared to monolithic kernel? Are you sure that wouldn't fall under this license? I think what it comes down to is that code written by a software engineer at Google should result in an exclusive competitive advantage, i.e. This may be in an effort to address the shortcomings Android has experienced. In its current form, I wouldn't like to have this in our code base. All Zircon system calls except the wait calls are asynchronous, non-blocking and preemptable. Just because it has a computer in it doesn't make it programming. Even if we don't have software patents, their effects are felt quite strongly, see for instance linux distros which did not ship with correct font rendering until the apple patents expired. (For gaming, think of being able to have a game DMA from the disk directly while at the same time being … … It's the same kind of "if we make it inconvenient..." policy that prevented the modernisation of GCC for years and years, and now everyone is moving to LLVM instead. So be surprised. [–]thinsteel 10 points11 points12 points 2 years ago (0 children). 3) Considering current monolithic kernels architecturally are strictly tied to current superscalar CPUs, is Google long run goal to run Fuchsia on new generation CPUs built with in mind a microkernel OS.
