When considering ways to spread interrupts from one device among multiple cores, I can’t not to mention MSI-X. The thing is that MSI-X is actually the right way to do the job.
Interrupt affinity, which I discussed here and here, has a fundamental problem. That is inevitable CPU cache misses. To emphasise this, think about what [...]
One of the features of x86 architecture is ability to spread interrupts evenly among multiple cores. Benefits of such configuration seems to be obvious. Interrupts consume CPU time and by spreading them on all cores we avoid bottle-necks.
I’ve written an article explaining this mechanism in greater detail. Yet let me remind you how it works [...]

Backing up Linux installation and restoring it, is perhaps one of the most fundamental tasks that every system administrator has to deal with.
Here are some [...]
About this article
I would like to do two things in this article. First I would like to tell you about SSH. How to make it work. How to use public key cryptography to login to a remote computer. How to execute remote commands and copy files to/from a remote machine.
On the other hand, I would [...]
