Jonathan on OpenSolaris

As Alan points out, Jonathan had a few comments about OpenSolaris in an interview in ComputerWorld. One interesting bit is an “official” timeline: We will have the license announced by the end of this calendar year and the code fully available [by the] first quarter of next year. I can tell you the OpenSolaris team [...]

More on OpenSolaris

So Novell has made a vague threat of litigation over OpenSolaris, which was prompty spun by the media into a declaration of war by Novell. But it has generated quite a bit of discussion over at OSNews. The claim itself is largely FUD (the “article” is little more than gossip), and the discussion covers a [...]

Inside the cyclic subsystem

A little while ago I mentioned the cyclic subsystem. This is an interesting little area of Solaris, written by Bryan back in Solaris 8. It is the heart of all timer activity in the Solaris kernel. The majority of this blog post comes straight from the source. Those of you inside Sun or part of [...]

Sun and Linux

If you haven’t already, go check out Tom Adelstein’s article at LXer, as well as Jim’s blog entry. Quite a departure from the usual Sun analysis. It’s an interesting take: Sun is (and has been) doing great things, but corporate messaging (both our competitors and our own) has muddied the waters to the point where [...]

Dual Core Opterons

So it’s no secret that AMD and Intel are in a mad sprint to the finish for dual-core x86 chips. The offical AMD roadmap, as well as public demos have all shown AMD well on track. The latest tidbits of information indicate Linux is up and running on these dual-core systems. Very cool. Given our [...]

Debugging on AMD64 – Part Three

Given that the amd64 ABI is nearly set in stone, and (as pointed out in comments on my last entry) future OpenSolaris ports could run into similar problems on other architectures (like PowerPC), you may wonder how we can make life easier in Solaris. In this entry I’ll elaborate on two possibilities. Note that these [...]

RSS-friendly code samples?

So in the past two days, my posts have contained a lot of code/text samples, that have to be formatted in a fixed with font and have their spacing preserved. Previously, I’ve just been using <pre></pre> tags around these samples. This work on blogs.sun.com, but I’ve found that this wreaks havoc with some RSS readers [...]

Debugging on AMD64 – Part Two

Last post I talked about one of the annoying features of the amd64 ABI – the optional frame pointer. Today, I’ll examine the much more painful problem of argument passing on amd64. For sake of discussion, I’ll avoid structure passing and floating point – nasty little kinks in the problem. Argument Passing on i386 On [...]

Debugging on AMD64 – Part One

The amd64 port of Solaris has been available (internally) for about a month and a half, and the rest of the group is starting to realize what those of us on the project team have known for a while: debugging on amd64 is a royal pain. The difficulty comes not from processor changes, but from [...]

Back from the dead

Despite what it may seem, I have not fallen off the face of the earth. Those of us in the solaris kernel group have been a little busy lately, as we’re in the final stretch of Solaris 10. Hopefully, this post will be the start of a return to my old blogging form… A few [...]
