Blog: 19 March 2014 - Laptop choices and aftermath

In November I was lamenting the lack of selection in credible Haswell-powered laptops for Mesa development. I chose the 15" MacBook Pro, while coworkers picked the 13" MBP and the System76 Galago Pro. After using the three laptops for a few months, I review our choices and whether they panned out like we expected.

Blog: 17 November 2013 - Difficulty in Finding a Good Development Laptop

When I started at working at Intel last year on the open source 3D driver I was given a spare Lenovo T420s (Sandybridge) as my development machine. Almost everyone on my team had upgraded to Ivy Bridge by February, but I planned just to hold out a few months until Haswell was released. I then spent all summer wondering where the Haswell laptops were, and only now, five months later has Lenovo released Thinkpads with Haswell. It's time for a new development machine, and after months of research the only conclusion I've come to is that it's really hard to find a good laptop for my (admittedly strange) case.

Blog: 06 July 2012 - My time optimizing graphics performance on the OLPC XO 1,75 laptop

Last summer after a year of graduate school, I was looking for an interesting project to work on. After asking around, Chris Ball found me in the #xorg-devel IRC channel and set me up working with One Laptop per Child. I started working with Chris and Jon Nettleton on improving the graphics performance of the ARM-based XO 1.75 laptop. The graphics drivers were in a state of flux, and in a number of cases the Sugar interface felt noticeably slower than on the VIA-powered XO 1.5. We wanted to know why it was slower and how to quantitatively measure graphics performance of real-world applications.

Blog: 17 May 2012 - Optimizing pixman for Loongson: Process and Results

The Lemote Yeeloong is a small notebook that is often the computer of choice for Free Software advocates, including Richard Stallman. It's powered by an 800 MHz STMicroelectronics Loongson 2F processor and has an antiquated Silicon Motion 712 graphics chip. The SM712's acceleration features are pretty subpar for today's standards, and performance of the old XFree86 Acceleration Architecture (XAA) that supports the SM712 has slowly decayed as developers move to support newer hardware and newer acceleration architectures. In short, graphics performance of the SM712 isn't very good with new X servers, so how can we improve it?

Blog: 02 August 2011 - New multilib N32 Gentoo MIPS Stages

Gentoo/MIPS has been in, well, not great shape for quite some time. When I was going through Gentoo recruitment, there were no stages (used for installing Gentoo) newer than 2008, so this was one of the main things I wanted to improve, specifically by creating new N32 ABI stages. Even though the N32 (meaning New 32-bit) ABI was introduced in IRIX in 1996 to replace SGI's o32 (Old 32-bit) ABI, Linux support for N32 has lagged behind until the last few years. Now, I'm pleased to unofficially announce new multilib N32 stages and that we'll be supporting as the preferred ABI.
