If you want to know how much memory the kernel uses. there's a lot of conditional code compiled or not depending on the chosen configuration, code not necessarily in dynamic loaded modules but built in the core. Projects hosted on Google Code remain available in the Google Code Archive. The Linux Foundation has registered trademarks and uses trademarks. The Device Tree Blob(.dtb) is produced by the compiler, and it is the binary that gets loaded by the bootloader and parsed by the kernel at boot time. It would cost over $1 billion (a Gigabuck) to develop this Linux distribution by conventional proprietary means in the U.S. (in year 2000 U.S. dollars). All documentation for ZoneMinder is now online at https://zoneminder.readthedocs.org. Learn how to install Visual Studio Code in Ubuntu and other Linux distributions. Why do the data and code segments completely overlap in Linux? @JonathanLeaders: Yes - and as well as modules for strange devices, there are modules for obscure filesystems, networking protocols, etc... @JonathanLeader I remember when Linux was starting - even getting the installer to work (if it even had an installer!)

Sponsored links Dried goldfish became alive after re-introducing into water. For distributions like Ubuntu, a single 40MB Kernel package is acceptable. (The size of the Linux kernel source code has been increasing nearly exponentially ever since its inception, soaring from 0.2MB and 10,239 lines of code for version 0.01 in 1991 to 212MB and 5.93 million lines of code for version 2.6.0 in 2003.) The Linux kernel has around 27.8 million lines of code in its Git repository, up from 26.1 million a year ago, while systemd now has nearly 1.3 million lines of code, according to GitHub stats analysed by Michael Larabel at Phoronix. See "ForumPost.txt" or ForumPost.md for the post in which it leaks, if you want to know how it is all set up and the likes. The kernel itself is hosted on kernel.org. A free C, C++ and Fortran IDE. The ubi->min_io_size is the minimal I/O unit size, which is equivalent to the NAND page size. On ARM all device tree source are located at /arch/arm/boot/dts/. Building of small stripped-down kernels is supported by config options to control #ifdefs. The future doesn't seem to be an issue either. With the help of an adequate compiler, for example GCC, your source code is translated into object code… The answers so far seem to be "yes there is lots of code" and nobody is tackling the question with the most logical answer: 15M+? What are the contents of this monolithic code base? The JFFS2 images generated by the mkfs.jffs2 program were padded to the physical eraseblock size and were later flashed to our NAND. @JonathanLeaders: I've done turing complete compilers for LISP like languages in less than 100 lines, with test programs rendering Mandelbrots. Check our new training course. Why do we use trigonometric functions to model waves? 1.9 million lines for supporting different processor architectures. counting modules isn't enough, a lot maybe builtin by config, I think from this we can conclude Linux kernel is massive because it supports all sorts of device configurations, not because it's outrageously complex. ZoneMinder is an integrated set of applications which provide a complete surveillance solution allowing capture, analysis, recording and monitoring of any CCTV or security cameras attached to a Linux based machine. You might still want to use the one in this file in order to: 68: ... _int_malloc after constant propagation of the size parameter. The top contributors by email domain were Intel and Red Hat (Google’s general gmail.com aside) and the top contributing individuals were Linus Torvalds, with 3.19 per cent of the commits, followed by David Miller (Red Hat) and Chris Wilson (Intel). This otherwise good/valuable answer suffers from a distinctly angry and combative tone. Looks incredibly hard to pull off if you don't just forsake any kind of memory protection at least.
