Blog: 11 April 2010 - My Google Summer of Code proposal

I've been involved with X.Org for a few months now. I want to increase my involvement, and at the same time learn the ropes. I also need something to do this summer–and that's why I've applied to the Google Summer of Code.

Blog: 14 December 2008 - The State of Alpha Linux

Software is never finished; it's forgotten. There is always one more enhancement to be made or one little quirk to work out. Sometimes there are even big problems. It happens from time to time. It's expected, and it's expected that the problems will be fixed. After spending quite a bit of time recently working with Linux on the Alpha platform, I've come to realize we face some very serious problems. And unfortunately, these may not ever be fixed, putting in jeopardy the future (hah!) of Alpha/Linux. I decided to articulate these problems in an email to the Linux on Alpha Processors mailing list in order to inform and ultimately find solutions and breathe a bit of life back into Alpha/Linux. I'd like to think that Alpha/Linux isn't a piece of forgotten software, not yet.

Blog: 12 December 2008 - Status of X11 on Alpha

As mentioned yesterday, X.Org 7.4 (xserver-1.5 and newer) cannot operate on Alpha due to way it accesses PCI resources such as ROM information and video memory. Kernel Bug 10893 was filed 6 months ago, but nothing has been fixed. A work-around is to implement a fallback in libpciaccess that would access /dev/mem directly, as previous Xservers do. Unfortunately, no one appears to care enough about X support on Alpha to implement it.

Blog: 18 July 2008 - Radeon X1550 in an SGI O2?

In a thread on the SGI Enthusiast site, Nekochan.net, about Linux compatibility with SGI's MIPS based line of workstations, a user, tillin9, suggested the possibility of installing modern, off the shelf graphics cards in the SGI O2 under Linux. The O2 is equipped with a single PCI slot for expansion, so physically installing a new graphics card is no problem. Unfortunately, graphics cards require special initialization code, stored in the card's ROM, to be run at boot time. Since the Radeon's initialization routine has to be able to execute on the processor architecture in the computer in which it's installed, different code is required for x86, PowerPC, PA-RISC, SPARC, and MIPS. Since there weren't any PCI Radeon's made for MIPS powered workstations, surely ten years later, a modern Radeon would never work in an old SGI workstation...
