LAPTOP NEWS
1. Ivan Krstić released the OLPC security specification this week. (Please see Bitfrost for an overview.) The specification will go through a rigorous review process in parallel with coding and testing, which has already begun.
2. Firmware: Mitch Bradley is making progress on the fastboot/resume infrastructure, with a power-up-to-running-Linux-kernel time of three seconds. He is also tracking down a problem with the USB2 driver in the kernel; it behaves strangely with the fastboot underpinnings.
3. Kernel: Linus Torvalds released 2.6.20 on Sunday. Andres Salomon merged it into an experimental build.
4. Performance: Chris Ball isolated a long-standing Python performance problem to our use of the -fPIC compiler flag. When we switch to the next release of Python, Version 2.5, which we have scheduled for later in the month, we should see a speedup of up to 40% under high load, plus an improvement to Python's startup time.
5. Chris also added automated graphing support to the Tinderbox, which now displays graphs of boot time and X11 performance on the main Tinderbox page. This will make regressions stick out, and is already displaying a recent slowdown in boot time. The next steps for the tinderbox are automated power-rail measurements in the Tinderbox.
6. The PepperPad team compared our performance to theirs, and found that our GX-500/366MHz is being outperformed by a reference board running a GX-466/333MHz. The benchmarks make it look like memory bandwidth is involved—perhaps we are setting our memory timings too conservatively? Chis and Richard Smith will investigate.
7. Jeremy Lueck has built the “$10 Laptop” by putting a Linux OS image running Sugar on a USB stick. Porting to a virtual machine allows the Sugar OS software to be run on any hardware that supports the virtual machine: Moka5's LivePC engine. (See Virtualized_Sugar for details).
