Explore the Linux Memory Model

Posted by ScuttleMonkey on from the building-from-the-ground-up dept.

Constable On Patrol writes to tell us that IBM DeveloperWorks has an interesting look at the 'fundamentals of how memory is constructed and managed' in the Linux memory module. The article serves as a great intro to the basics of memory management for Linux design and implementation. From the article: "This guide includes an examination of the segment control unit and the paging models as well as a detailed look at the physical memory zone."

    Kudos to whoever modded this down before another comment was posted. Someone's on the ball.

    This is article doesn't really contain any new (or even hard-to-find) information. Most of it covers basic x86 memory architecture, which any driver developer (on any OS) already knows. The remaining few paragraphs are basically just excerpts from the memory architecture chaper of any decent Linux kernel book.

    If you really want to learn about the Linux memory architecture, get Mel Gorman's book "Understanding the Linux Virtual Memory Manager".

      IBM developerworks rarely acheives anything else.

      The caption did say it's an INTRO to the BASICS of the Linux Memory Architecture. What more do you expect?

      And for those of us who don't have time to read entire books, we can take a look at this and learn a bit about it.

      People to stop wasting other people's brain space writing their shitty little superficial tutorials on IBM's website every time they learn something from another website. The world is overflowing with superfluous O'Reilly-grade tutorial 101 material.

      Sure there are some winners and losers on DevWorks, like anyplace else. This article is clearly aimed at beginners, in fact it says so. No doubt these are some IBMers at the labs, getting a few extra points for writing an article. But there are excellent articles too, here's on one performance. If you think you can do a better job, by all means submit your article, to DevWorks, LinuxJournal, wherever. Put up or shut up.

      > Put up or shut up.

      If I should have to put up with developerworks or shut up about it, then you should have to put up with me or shut up about it. There is a third alternative: we can talk freely about it, telling people what we each think of the quality of a source without barking commands at each other ("Put up or shut up" is an imperative utterance and a rude one at that).

      And I stand by my statement on the rarity of articles like the one you just linked to (which is, indeed, insightful - if a little underwhelming) - I developed my opinion based on reading through a bunch of recent articles and finding very few worth thinking about.

    Less space than the human brain, bad wireless support. Lame.

      For you maybe, I've never had much trouble getting wireless working, sure the kernel doesn't support it off the bat. (Although it does support the new intel wifi drivers). Take your trolling somewhere else.

      BTW, I'm connected on via my ipw2200 wireless card, using 2.6.14. :)

  5. Testament To Design by ObsessiveMathsFreak · · Score: 1

    It is a testament to the Linux Virtual Memory model that it is so efficient at masking the underlying memory allocation and access operations from the user that harldy anyone on Slashdot really cares enough to read this model.

    Linux Memory Management. We Salute You!
