The 2.6 Linux kernel employs a number of techniques to improve the use of large amounts of memory, making Linux more enterprise-ready than ever before. This article outlines a few of the more important changes, including reverse mapping, the use of larger memory pages, storage of page-table entries in high memory, and greater stability of the memory manager.
Nice article thx
Great article but it’d be nice to see more articles on Embedded Linux. It think it’s going to become more important as computer driven appliances begin to take off. Hey, what’s with the BSA adds? I actually looked over my shoulder when that thing popped up
The related article links are a nice addition.
No default crash dumps or builtin kernel debugger, not ready for enterprise use. How can anyone trust their business to an OS if if the technology isn’t in place to properly test it? Seriously! Linux is the only ‘major’ OS that does not have such facilities. Mac OS X has it, Windows XP has it, all of the BSDs have it, as well as any proprietary UNIX that I have ever heard of. It’s pure madness to have such blind faith in anything, let alone this.
euh… sorry, but it’s available if you want it (and it will be included later) – think distributions here:

Hi
“No default crash dumps or builtin kernel debugger, not ready for enterprise use. How can anyone trust their business to an OS if if the technology isn’t in place to properly test it? Seriously! Linux is the only ‘major’ OS that does not have such facilities.”
I have been seeing this same post on every linux kernel news on osnews. get a life. its optional and you can include it if you want to.
linux is now on a level playing field with bsd
Proper debugging tools shouldn’t be optional, but should be a basic part of your kernels complete breakfast. Linux is not yet on a leveel playing field with the BSDs. Saying so is laughable.
*Shrug*
Perhaps if it’s repeated often enough you Linux guys’ll get so sick of hearing it that you’ll make Linus include them.

Uh, huh. So assuming your post has some merit? What is it you know that Linus and friends don’t know? He’s explained his reasons. Were are yours?
He’s explained his reasons
I too have explained my reasons, and they’re shared with many folks brighter than either me or Torvalds. He’s a good coder, but a terrible software architect. He is also stubborn, and refuses to do basic things like this, and I’ve heard no well thought out reason from him, and I’ll not repeat mine for you as I’ve explained myself in detail before.
Oh yea the Blue Screen of Death
Heh. The last time I saw one of those was under Windows 98 (I’m unsure if it had kernel debugging). I’ve yet to see one under Windows 2000 or Windows XP. Your response is silly.

Uh, huh. Well I see you didn’t include a URL to these previously explained reasons, as part of your “I will not repeat myself” policy.
“Perhaps if it’s repeated often enough you Linux guys’ll get so sick of hearing it that you’ll make Linus include them. ”
This is OSS (same as the BSD’s). No one *makes* anyone, do anything. Simple as that.
Also as Lennie already mentioned the needed tools are optional, but there. Same as in Windows. Those who need them, can get them. I find your post without merit.
The kernel debugger is availabel to those who want/need it. What’s your problem? Oh, I get it, you’re only trolling…
Everyone, please ignore anonymous trolls. Thank you.
It’s lookin like “A nun, he moos” is going “Report abuse” happy.
FYI, I didn’t report a single one of your posts for abuse, because I don’t think simple trolling meets the requirements for it. So there.
Stealing other people’s nickname is frowned upon by moderators here. We had problems with a kid who kept posing as others on this site some time ago. Please don’t.
My appologies.
