New toy...the Lemote Yeeloong netbook

E-Mail PDF

Before the netbook-boom called 'mini notebook', Lemote now promotes it as netbook (what it really is). The specialty of that little thing is the hardware: Not an Intel Atom or some AMD CPU, but a 900Mhz Mips chip. Honestly, after my disaster with something ARM-based (NSLU2, it still is bricked and will never be revived I think), I wanted something more end-user friendly and the Lemote is just that. Equipped with a full-fledged desktop installation (the Debian mipsel variant) it allows installing Gentoo with few problems. Chrooting and installing the stage tarball from Zhang Le gets you off quite fast. The provided kernel did not boot, but Le gave me a newer one, which worked just fine after creating some missing device files (console, tty* and pty*, see man mknod). Meanwhile I have compiled my own kernel and the system just runs with LXDE...so finally a possibility to have the third Gtk-based destop installed. Gnome on sol (the big iron desktop), Xfce on the main lappy (called terra) and LXDE now on mars. Performance is good, for surfing and mailing it is more than sufficient, compile times are ok (even GNU Emacs runs), but the battery is way too small (1.5 hours only, but a peak of 14W consumption, while having 12W during normal surf sessions).

The Loongson processor seems to me as the future of the Gentoo Mips port. Supporting the old SGI machines is nice but they will eventually die out, while Lemote actively works on new machines and supports Linux as its main platform (they don't have any other choice apart from the BSDs anyway). Ordering is really simple: Either use Lemote directly (and handle all customs yourself), use KD85 (what I did, really pleasing experience, shipped from Belgium) or Tekmote from the Netherlands.

Zhang Le (r0bertz) and Stuart Longland (redhatter) wrote enough about the Loongson processor and the Gentoo support in various entries on their blogs, so I won't go into more details.

Chinese MIPS machines seem nice, but way overpriced for what they offer...

Why is it overpriced ? You have a CPU capable of running anything, 1Gb of RAM, a good display, a 160Gb HD, etc... So from the hardware side it's very good for the price.

In *addition* every software is free, from the bios to the firmwares.
For a hacker standpoint this is the _best_ computer available.

CPU is way below x86, regarding its capabilities as well as its complexity.

Everything else onboard is generation or two behind todays standard and LCD is average at best.

Chinese stuff is maybe not such cr*p as it used to be, but neither is its price.

The price is average for what you get. The CPU is not slow when compared to Atom. There is nothing wrong with the LCD. Network/WiFi/Memory/... seems current generation.

As it was pointed out already, the battery life is very poor, so it fits not all use cases. But if you don't depend on long battery life, the fact that the Yeelong is fully hackable makes up for that.

From a hacker's perspective it is perfect, because usable but also interesting. As a user you must love to play around with such things, but for the average netbook use-case it is more than sufficient.

The poor power manager on that system is really a problem. Otherwise, how can you explain that a chip which draw less power has shorter battery life?

Because the battery is so small, the peak power is 14 Watt which is not bad, while it has 12W on a unused desktop.

So is the Lemote Yeeloong a cheap alternative to a commercialy available x86 notebook if i just want to check emails and stuff or is it at the moment more like a toy for hackers but not really practical for the standard user?

I've been using a Yeeloong as my main workstation for a few months now.... They're not the fastest on the LAN, but they're more than capable as a modest portable workstation for doing various tasks. I've been doing all sorts of things with mine, including various text editing/spreadsheeting tasks (koffice, lyx), database work, coding in numerous languages, electronic circuit design and PCB layout (gEDA), circuit simulation (qucs), and the usual web browsing tasks.

I've even hooked the netbook up to my Kenwood TS-120S HF transceiver and used it as a PSK31 terminal on 20m during the International Lighthouse Lightship weekend, calling CQ as "VK4MM/LT"... apparently putting out a very clear and readable signal which was picked up by a few US amateur operators.

Video editing is also possible... to a limited extent. I found processing individual frames using netpbm isn't much slower on the Yeeloong, compared to an AMD Turion X2 laptop I was also using. The AMD was faster, but only marginally.

Battery life... the machines are equipped with a 23Wh battery pack (3-cell Lithium Ion). I find I get about 1.5 hours, which if you take into account the 14W power drain, 1.5 hours is about right. This is while flogging the hell out of it... "emerge -j --load-average 1.0 kde-meta". I got much of KDE 4.3.0 installed whilst in transit between home (Brisbane) and work (Laidley) on the train.

An Asus EEE might score a far longer battery life, but I think many of them have a much larger battery pack, and are significantly heavier than the Yeeloong (which is light as a feather)... if we are going to compare them, we should be comparing apples to apples here, and try to compare the Yeeloong with a machine that has an equivalent size battery pack.

A long chain of conversions and wikipedia pages suggests that the 900MHz Loongson 2F in the Yeelong may actually be a touch faster than the simpler Atom CPUs in most netbooks despite the 1.6–1.66GHz clock speed of the latter. There's plenty of room for error in that "long chain of conversions", but descriptions of the two chips do suggest that the Loongson will be faster per Hz than the Atoms typical of netbooks.

Regarding battery life, the EeePC wikipedia page describes one of the EeePC models as getting 10.5 hrs use from a 63Wh battery, suggesting an average use of 6W, compared to the "12W on [an] unused desktop" for the Yeeloong. The EeePC model in question has a slightly larger screen, though I'm not sure if it has a spinning hard disk or not.

(Of course, working well with Free Software will for many people be much more important than a few W power consumption or marginally different CPU speed.)
