How PowerTOP, LatencyTOP, and Five-Second Boot Improve Desktop Linux
,----[ Quote ]
| O'Reilly News recently interviewed Arjan van de Ven about his efforts to
| improve Linux performance and reduce power consumption. Arjan works for Intel
| in the Open Source Technology Center. This interview is approximately 30
| minutes.
|
| One of the projects you're probably most known for in the past couple of
| years is the PowerTOP utility, which I found very fascinating. Looking at
| some of the gains you've made over the past 18 months, it seems like
| Linux-based devices are saving a lot more power than they used to. What do
| you consider the big successes in the past year and a half?

MontaVista Linux drives Dell's quick-boot feature
,----[ Quote ]
| CEO Rusty Harris revealed MontaVista's role developing the quick-booting,
| ARM-based processor subsystem expected to ship this year in select Dell
| laptop models. The "Latitude ON" feature aims to give enterprise laptop users
| instant boot-up and access to select applications, with multi-day battery
| lifetimes.
|
| The Latitude ON feature is expected to arrive "in the coming months" on the
| Latitude E4200 (pictured above) and E4300, the two lightest-weight models of
| the five re-engineered Dell Latitudes announced by the company in August.
| Latitude ON uses "a dedicated low-voltage sub-processor and OS that can
| enable multi-day battery life" for the Windows Vista notebooks, Dell said.
| Dell also said the technology will provide access to the web, email,
| attachments, calendar, and contacts "in seconds."

Dell introduces ten new laptops
,----[ Quote ]
| On is a flash-based barebones Linux install that gets you up and running, on
| the Net, and with much of what you need to run the computer in instantly.
| Dell went to great pains to avoid saying the L-word though, it might anger
| the very touchy gods atop mount Redmond.

Are “instant on” notebooks the future?
,----[ Quote ]
| If I think about my normal notebook usage patterns, I’m pretty sure I could
| spend a good 80 - 90% of my time in the instant on environment and only boot
| into Windows when I needed to do something specifically Windows-centric. In
| fact, given a properly set up Linux distro as the main OS (which should be a
| snap to set up since these systems would/should already be Linux-compatible
| because they are running the Linux-based instant on OS ) which would allow me
| to handle Microsoft Office docs, and a VPN, I could do away with having
| Windows on the system altogether and simply connect to a secondary
| Windows-based PC when I wanted that functionality (when on the road I rarely,
| if ever, need to run anything heavy such as Photoshop).

Dell’s comeback machine
,----[ Quote ]
| There are some surprises beneath the surface of the Latitude line as well.
| One is an optional Linux-based low-power mode called Dell Latitude On, which
| boots in two seconds. It offers more than a day’s worth of battery life for
| basic tasks like web surfing, Exchange e-mail, and viewing e-mail
| attachments, and runs on an ARM-based (ARMH) chip rather than the main Intel
| processor. (HP and Lenovo laptops offer similar Linux modes, but with fewer
| capabilities.)
