CPU Flags and Meanings

Filed under: General Linux — TheLinuxBlog.com at 11:38 pm on Tuesday, August 11, 2009

Having a brain that is somewhat comparable to a sift for remembering acronym’s, I’m always asking a friend which (I, probably incorrectly call) CPU extension is for virtualization. So I figured I’d blog about this topic. This page CPU feature flags and their meanings clearly explains each of the flags that may be on your machine, which you can check what your CPU supports by typing:

cat /proc/cpuinfo | grep flags

Secure Virtual Machine. (AMD’s virtualization extensions to the 64-bit x86 architecture, equivalent to Intel’s VMX, both are also known as HVM in the Xen hypervisor.)

So to answer my own question SVM and VMX are what to look for when considering a CPU for virtualization. My laptop supports VMX, but my desktop doesn’t. Considering I’d rather do my virtualization on my desktop, I’ll have to upgrade my CPU. Now all I need to do is find out where to find this information for AMD processors and hope I can get a CPU for my outdated socket type. I don’t even think that it is AM2 :(

New Linux Desktop

Filed under: Linux Hardware — TheLinuxBlog.com at 5:50 am on Wednesday, February 6, 2008

I got a new Linux desktop for use at my office.  All right, so its not entirely new but the price was right!

Here are the specs:

Motherboard: MSI K9N6SGM
CPU: AMD Sempron 3400+ 256 KB Cache, 1808.430 MHz and 3620.23 Bogomips (Slightly more than my laptop)
Ram: 1GB Generic Ram
Hard Drive: 80GB Sata Drive
Power Supply: 350 Watt

Now, considering I only paid around $200 for all of this I think I did pretty good. I already had an fairly new e-machine that was given to me with a fried motherboard, power supply and hard drive, so I used the Case DVD, Rom and CD-RW drive. Its a pretty fast machine so far. The onboard video happens to be a GeForce so I’m happy about my 3D Graphics support.

What is even better is that if you would like to support The Linux Blog and happen to need a new computer, you can call The Tech Fellows at (704) 780-4932 and tell them that The Linux Blog sent you and they will hook you up. Even if you just need parts they can help and normally can match Tiger Directs prices.

I will let you know how the rest of the installation of Slackware goes and post some benchmarks some time.
