'Fuchsia Is Not Linux': Google Publishes Documentation Explaining Their New OS (xda-developers.com)

Posted by BeauHD on Wednesday April 11, 2018 @10:40AM from the not-what-it-looks-like dept.

An anonymous reader quotes a report from XDA Developers: You've probably seen mentions of the Fuchsia operating system here and there since it has been in development for almost 2 years. It's Google's not-so-secretive operating system which many speculate will eventually replace Android. We've seen it grow from a barely functional mock-up UI in an app form to a version that actually boots on existing hardware. We've seen how much importance Google places on the project as veteran Android project managers are starting to work on it. But after all of this time, we've never once had either an official announcement from Google about the project or any documentation about it -- all of the information thus far has come as a result of people digging into the source code.

Now, that appears to be changing as Google has published a documentation page called "The Book." The page aims to explain what Fuchsia, the "modular, capability-based operating system" is and is not. The most prominent text on that page is a large section explaining that Fuchsia is NOT Linux, in case that wasn't clear already. Above that are several readme pages explaining Fuchsia's file systems, boot sequence, core libraries, sandboxing, and more. The rest of the page has sections explaining what the Zircon micro-kernel is and how the framework, storage, networking, graphics, media, user interface, and more are implemented.

  Yes, it is why most microkernels suffer from poor performance. As the message goes through 3 different process spaces it causes latency. It is the context switch and copy that causes the jitter. With the speed of most CPUs these days it is not as noticeable. But a proc that uses a lot of syscalls into other things can cause significant overhead in just message passing. Linux/windows/AppleOSX uses a shortcut of putting part of the kernel (or all of it) in the same memory space as the process and treat it as a function call instead of a message. They then lock it away from the process by using CPU flags and rings.
  The successful microkernels typically have had to cheat out the messaging bit in some way. Usually with in process memory or security shortcuts (ie none).
  Like I said it should be interesting with a company like google studying the idea. They have hovered up any worth hiring already...

  The early microkernels had problems, but a 2nd generation of 'L4' kernels, pioneered by Jochen Liedtke (who died an untimely death at age 48) seems to have gotten around that. From the wikipedia article on L4 microkernel family:
  
  The poor performance of first-generation microkernels, such as Mach, led a number of developers to re-examine the entire microkernel concept in the mid-1990s...
  Detailed analysis of the Mach bottleneck indicated that, among other things, its working set is too large: the IPC code expresses poor spatial locality; that is, it results in too many cache misses, of which most are in-kernel...
  Liedtke came to the conclusion that several other Mach concepts were also misplaced. By simplifying the microkernel concepts even further he developed the first L4 kernel which was primarily designed with high performance in mind. In order to wring out every bit of performance the entire kernel was written in assembly language, and its IPC was 20 times faster than Mach's.[4] Such dramatic performance increases are a rare event in operating systems, and Liedtke's work triggered new L4 implementations and work on L4-based systems at a number of universities and research institutes,

  Actually, Google will make Fuschia work as a smartphone/tablet platform and whatever else. From a design perspective, it's actually quite bad.
  
  When I first started reading the code to Fuschia, I was going line by line asking myself "Haven't we already made this mistake before?". It was like one major compilation of "I took an OS course based on Tananbaum's book and decided just to copy every mistake we never learned from". And in the end we have a brand spanking new 30 year old operating system.
  
  Ok, I'm being harsh and it's only partially fair. Let me start with your issues.
  
  It's not necessary to sort out the issues with latency and message passing. They are making a real-time (or near real-time) operating system which in its own right already suggests that they're willing to sacrifice performance in favor of deterministic time. Telephones always benefit from real-time kernels in the sense that it allows dropping overall transistor and component count. Every telephone which ever boasted 4 day batteries ran real-time operating systems and it was generally a good idea.
  
  Secondly, there's been a pretty huge move in Firefox and Chrome to optimize their shared memory systems to reduce or eliminate hardware locks by marshalling the memory reads and writes. Add to that that almost all modern development paradigms are asynchronous programming... unless you're stuck with some shitty language like C or C++, and most of the switch and latency issues are irrelevant. This is because you can keep multiple cores spinning more or less non-stop without much concern for kernel level inter-thread synchronization. Take it a few steps further and expose things like video hardware access directly to individual applications that would operate their own compositors based on a GPU context and apply shaders to support windowing type tasks... then it's going to be quite impressive and the locks should be a lot less relevant.
  
  From that perspective, I don't see a good solution to the audio problem as I've never seen a sound card which would support the principle of shared resources. I don't think it would be even mildly difficult to design such a device though. The only real issue is that if mixing is moved entirely to hardware, then depending on the scenario, it would be necessary to have at least quite a few relatively long DSP pipelines with support for everything from PCM scaling to filtering. There's the other problem which is that protection faults to trigger interrupts could be an issue unless there's some other creative means of signalling user mode code of buffer states without polling. Audio is relatively unforgiving of buffer starvation.
  
  So, let's start on my pet peeves.
  
  Google's been working on this for some time and they still don't have a system in place for supporting proper languages. C and C++ are nifty for the microkernel itself. But even then, they should have considered Rust or rolling their own language. This world has more than enough shitty C based kernels like Linux and BSD. If you want to search the CVEs and see what percentage of them would never have been an issue if the same code was written in a real programming language, be my guest, but I'm still sitting on WAY TOO MANY unreported critical security holes in things like drivers from VMware, drivers from Cisco, OpenVPN certificate handling code, etc... I absolutely hate looking at C or C++ code because every time I do, unless it's painfully static in nature, it's generally riddled with code injection issues, etc...
  
  And yes, I've been watching Magenta/Fuschia evolve since the first day and I follow the commit logs. It's better than TV. It's like "We have a huge number of 22 year old super hot-shot coders who really kick ass. Look at this great operating system kernel" and it looks like some bastard high school or university project written by people who have little or no concept of history.

  The problem with microkernel performance is not due to latency for process switching and message passing.
  The problem is the synchronization between different parts. Imagine for instance a multi-threaded filesystem. A filesystem as whole has a certain state. That state describes all the files and directories, file sizes and contents. Now imagine that one of the threads makes a change to the state. The problem is how to get that state update to all the other threads with a minimum of a delay.
  In a monolithic kernel, the problem is solved by getting a lock, update the state, and releasing the lock. It's a very simple and efficient operation.
  In a microkernel, you need to send messages around. You can optimize the message passing itself, but you'll still have the problem that the receiving thread is doing other things, and only handles the messages at certain points. While it is doing those other things, it's working with an outdated version of the state. Basically you're getting into the design of distributed filesystems/computing, and this is a very hairy subject. The complexity of the problem is much larger than just sticking to simple locking.
  The traditional solution is to keep the filesystem (and similar parts of the OS) in a single thread. This may be a viable solution on some platforms (perhaps a phone or tablet), but it will quickly run into scalability problems on a large, general purpose computer.

  I suspect that what is bothering you is a process that is blocked on I/O, or your computer is starved for resources and swapping (which means everything gets blocked on I/O).
  Ultimately this comes down to the system attempting to keep all of the promises it's already made to you. Most of the time these promises are buffered writes which it has in RAM, and is pushing to your really slow USB drive or SD card as fast as it can. You interrupt it, but this does not interrupt the promises already made.

The system is responsible for reading what you type on the keyboard, for example, so in that case the system should have a very high priority so that it can service your interactive task.
  If only it was so simple, but in fact it's far worse than this. Not only does the OP want the interactive task to have priority to all possible resources over everything else, but that this priority inherits from this task to every task that is blocking it, including those access over all possible inter-task-communication methods. At the very minimum, it means that all of those IPC mechanisms need to be 'priority aware' and the kernel needs to arbitrate this correctly. It also means that all tasks must migrate away from any IPC mechanisms that don't have the structure to encapsulate the concept of a 'blocking request' -- shmem probably has to go.
  In other words, it's not enough to give my topmost process the highest priority to the disk, but if that process reaches to any other process, say a system service, then that process must, for the lifetime when it is services the request from the topmost process, also (temporarily) be granted highest disk priority. In a POSIXy world where processes often connect via (local, not AF) sockets, this means that the socket mechanism itself needs to somehow figure out if the request is blocking or if it is 'background priority'.

  It goes without saying that I agree with the parent poster on this...
  To add to this, it is my understanding that some of this IO is likely to be handled via DMA writes or reads. Interrupting something that is not actually costing you CPU time is something I'd think twice about. Of course with USB devices, I suspect the CPU has more involvement almost all the time, but I agree, better hardware could fix that.
  I haven't studied this OS, but I do wonder if perhaps we need a more hybrid approach. What I'm talking about is having a system with these cores,memory,etc set aside for hard real time tasks and resources that are not.
  A thread running on those cores would have to be deterministic, in that we know every iteration of the thread will complete in a bounded time and we know the total schedule of threads will not exceed the time allotted for threads.
  The problem, is once any task gets beyond a certain degree of complexity it becomes really hard to get that assurance. You can do it for some dedicated tasks with C or C++. I could poll a mouse or keyboard all day with dedicated resources and a hard real time OS and capture every keystroke or mouse movement without ever glitching. It would be trivial.
  What is not trivial, is taking that information, feeding it to the possibly managed rendering engine, allocating during runtime any new resources needed to render the updates, redraw anything affected, scale it if needed, plus keep the rest of the stuff running. (We are ignoring the fun that is the modern paranoid anti malware stuff.)
  I've played a lot of games with threading and affinity on windows. It does help, but only if you do it just right and only around the edges. Get it even slightly wrong and it can easily be worse than not setting anything at all. For instance if you have 2 physically separated cpu's, you can probably reduce jitter a bit if you keep real time tasks on one, and non real time on the other, assuming that load works out. Why does such stuff matter? Well it usually doesn't, when it does matter is because your preventing the process from moving around and loosing some of the benefits of cpu cache.
  Again, unless your trying to somehow capture uninterrupted data streams by polling or some other task you wish you weren't given, it is usually a fools errand, and probably is even then. Of course if I had that mythical system that was basically half RTOS, I could put the polling in there, where it is deterministic, then shovel up big buckets full for the non RTOS, which usually works better. (Good data acquisition cards do this for you, as does well most other good hardware..)
  Most of the time trying to second guess the scheduler is easier said than done, and, as mentioned it is easy to get it wrong. You could, for instance give your program so many resources that you indirectly starve resources from some other system task your program needs, or even worse some task set to a higher priority sits there spinning waiting for some lower level task to complete that will never run.
  Overall, I'm not sure the underlying OS is the biggest thing android needs, but again I'm not remotely an expert there. My guess is you have a fair chunk of not particularly efficient applications, combined with limited resources, combined with the crazy crap that is the modern web page.
  Seriously, we went from pages with barely any graphics, and all served from one server (usually), to the mess that is countless graphics, bad scripting, ad providers, tracking crap, databases, etc, etc just to load well weather.com.

  I also meant things like a user starting a processor-consuming task using a GUI, then not being able to stop that task via the GUI because the task is consuming all the processor and prevents the GUI from processing the stop request. So the computer carries on doing a pointless task.

LOVE the monitor, and I'm afraid to look at the new ones the graphics guys down the hall have (I can't afford to go buy one....). The OS though is just Too Different for me to deal with when I'm busy with trying to get back to being productive at work.

For Linux there is an existing path to get your patches into the main tree. Fuchsia is controlled by google completely and so will only support whatever Google wants, and will only be patched by Google.

The question is: why make such an effort when Linux is already there and can be modified to your needs.
One reason may be, that there is something you want to do fundamentally different, so it's easier to start a new project than change the old one to your needs.
Another thing may be that they want to get rid of (L)GPL-Licensed parts in their OS, and that may well be the more important motive here.
See here how the android website argues for other licenses than LGPL for User space apps:
https://source.android.com/set...
It could even be a move to prepare for a proprietary branch (the sources for which they have complete copyrights, i.e. that didn't incorporate patches from outside, can always be licensed under an additional license) and in the long run have a completely closed source OS.
This is just wild speculations since IANAL, but it might be be interesting what lawyers make of the change in licensing.

Wait states by Anonymous Coward · 2018-04-11 22:53 · Score: 0

Except for the workload of handling interrupts from communication networks and producing sound and video in real time, mobile devices are in a wait state most of the time. You can't compare the task switching in a mobile device to the work load of a server, supercomputer, or tpu training itself for deep learning. If the microkernel limits itself to mobile devices and the internet of things, then it doesn't appear to present an insurmountable performance challenges.
If the microkernel architecture is dedicated to protecting the privacy and security of its users on mobile devices and IOT, then the performance hit should be worth the sacrifice.
On the other hand, if Google plans to use Fuchsia in autonomous vehicles, then lives are at stake, and every nanosecond in the operating system counts to protect human lives and avoid unnecessary accidents.

Lots of OSes out there by OrangeTide · 2018-04-12 05:59 · Score: 1

Every year a good percentage of computer science and computer engineering undergrads write a small kernel for their coursework. It's not hard to write a kernel that solves a narrow set of requirements. When you have an every expanding scope, like in the Linux world, it gets hard. Linux has to run kiosks, mobile phones, desktops and supercomputers. And it's probably not the best possible kernel for any one of those problems, and certainly more complex than a kernel designed for a single specific purpose.
Why do we need Google Fuchsia? We don't really. But a whole lot of people leverage Little Kernel for their projects (my own company is using LK in 3 totally different ways). I blame LK for projects like Fuschia as it has turned into sort of a DIY Operating System kit.
If Linux and the BSDs are too complicated or you're just looking for some kernel you can hack up to meet your own special needs:
* NewOS
* Xv6 - a teaching OS. but people have patches for virtual memory and other goodies
* LK (little kernel) and for an example of a fork TLK (Trusted Little Kernel). LK is quite a good starting place for an aspiring osdev'r
* basekernel - rough starting place for making your own kernel
* FUZIX - a UNIX-like kernel geared toward 8-bit CPUs. but can be ported to bigger CPUs (there is a 68K port for example)
* TinyOS
* Femto OS - a kernel suitable for multitasking on small microcontrollers
* PonyOS - a graphical OS for people who love ponies (OMG Ponies). If you're looking for a more serious version see Toaruos.
There are hundreds of these hobby and learning OSes and several more complete and better established ones (like FreeRTOS).
