For the most part, Debian, Ubuntu (and derivatives), Gentoo, and Arch the top few of the most popular distributions for games (not to mention Steam can run on these, and that SteamOS was originally built on top of Gentoo, then later changed to a Debian base).

How is system call executed?

User Avatar

Asked by Wiki User

For a user most system calls are simply wrapped in simple command utilities such as chroot and mkdir and the like.

But system calls proper are made by software, plain and simple. Usually how it works on the low level is dependent on the architecture being used. For "simplicity" I'll refer to x86(_64).

When a system call is made, it's done by putting the parameters of the call in a series of general purpose registers in the CPU, then either signaling an interrupt or, in the case of 64-bit x86, actually using the syscall instruction.

What happens then is a context switch occurs, and the CPU is switched over to kernel mode and the kernel itself is actually running now and has your system call. Meanwhile, the process that made the system call is put in the "blocked" list until the needs of the system call are met.

Remember that a system call is a simple request for a service from the operating system by something in user space. Things in user space can't do a whole lot themselves in reality, and have to ask the operating system for a lot of support.

While an application can do a lot with the CPU, as soon as it needs any sort of hardware support, or more memory, or less memory, it has to ask the operating system for it. For example:

I wrote a text document in vi. To save, vi has to make a system call (Actually, a LOT of system calls.) to the kernel to actually write the buffer to disk.

Think of system calls as being among the building blocks of the actual execution of software on *nix systems. The process will happily use CPU instructions without operating system help, but applications make constant use of hardware in some way, and to do that, they have to use instructions for the kernel, who may or may not actually GRANT the requests based on permissions or sanity of the system call, as opposed to a CPU which will MOSTLY do whatever it is told even in user mode.

The only time a CPU will actually reject an instruction is if its bonkers. Either it's an opcode that makes no sense to the CPU or, more commonly, it is an opcode that requests memory be used in some way that is flat out disallowed in virtual memory. In those cases the CPU will usually fire off an exception and force a context switch to the kernel to handle the error. It'll be up to the operating system how to proceed, but usually, except in cases of page faults, this means death to the offending process. The cases where the CPU will reject an instruction because it's plain invalid or violates memory access rules is called a "fault."

What file system does Ubuntu or Debian use?

User Avatar

Asked by Wiki User

By default it should be using the ext3 file system, but you have a choice of several, including ext2, reiserfs, etc.

Newer versions of Ubuntu tend to install as ext4 file systems, however if you've upgraded from an older version then you'll keep your original file system.

Why does 'Error 1068 The Dependency Service or Group Failed To Start' appear when starting the remote access auto connection manager or print spooler in Windows XP?

Best answer is that the registry is corrupted you can do the steps on this page if you can get it to work. Another way is to just download a default services reg file. It will definitely fix your problem, however you may have to reload some programs or reactivate some needed services. It will also speed up your computer processing. You can go to www.blackviper.com and check out the downloads section for your Windows build or go to Windows Support website and check their downloads section for a similar file. This will save you time and headache of trying to get the program (or whole system in my case) to work with no result.

Make sure Network DDE and Network DDE DSDM are started in Services. You can get to services by going to Start, Run and typing Services.MSC

How do you turn any Linux distro's iso image into a LiveCD?

User Avatar

Asked by Wiki User

It is very difficult to build a LiveCD from scratch. Basically, you need a kernel that can read ISO9660 images, a file system image (either squashfs or cloop), and an overlay system, to make it look like you are changing things on the file system, but are erased on shutdown. The overlay is one of the most difficult things to construct from scratch, which is why I recommend you use a base CD from an existing LiveCD distro.

There are several distros you can use as a base, and several tools you can use to help you. Ubuntu, Debian, Knoppix, and Slax are the most popular bases for LiveCDs. To remaster the image, you can:

* Use Remastersys (for Ubuntu). * Use DRUDell (for Ubuntu) * Use Revisor (Fedora) * Use mklivecd (Debian and Madriva) * Use Custom NimbleX (online LiveCD creator, based on Slackware) * Do it manually, via the command line.

The instructions vary per distro on the command line. Basically, you copy all the contents off an ISO image, mount the compressed file system, copy it's contents to another folder, chroot into those contents, make changes, build a new compressed image, and build the contents back into an ISO image. While this method is more difficult (or at least more tedious), it allows you far more power to customize.

How do you install subwoffer in 2006 Kia Rio 5?

Asked by Wiki User

Thre are several different methods first assuming you have an aftermarket head unit,one option would be a custom enclosure,that could be built from MDF and an amp space could be included in the design. There are many sites on the web that are devoted to enclosure design based on the type/brand you have the manufacturer usually recommends a specific amount of air space . Its not difficult as most lumber suppliers will custom cut the pieces you need for about a buck a cut,all that's left is to assemble cover and mount. Good luck!

Can you safely use modern 2-34 shells in Winchester mod 12 chambered for 2-916 shells?

User Avatar

Asked by Wiki User

The Winchester Model 12 was one of the best pump shotguns ever invented, but I'm afraid trying to chamber a round 1/4 inch longer than the gun was designed to fire would be very difficult and the pressures generated would be higher than the 9/16 was designed to handle.

How do you install a 220 plug?

Asked by Wiki User

You need two hot legs of 110 volts to make 220. While each led is 110 volts to neutral, between the two hot legs you have 220v. You should have two different hot legs of 110, a neutral and a ground to meet code now a days.
