Finished slackware on Loongson

'lyh' successfully ported Slackware Linux on Loongson platform today. He says xfce4 and e17 nearly no problem on Slackware-Loongson and he is compiling and testing KDE.

Waiting for his screen shot.

QEMU running Win98 on Loongson

'jun7903' posted a message on Lemote BBS early this morning, which said he had made QEMU running Windows 98 on Loongson. Although QEMU on Loongson is not fully tested, it is the first time for a Windows OS to somehow "run" on Loongson2 platform. In 2006 I also saw WinCE running on GS32i (an improved Loongson I CPU).

I don't need Windows at all, but more functions are always better when it comes to marketing.

Known Problems in Loongson Box (Part)

As a product in testing, Lemote Box satisfies my need. However, there are still problems at present which are expected to be solved in future. Some friends asked me if they can get a Lemote Box. The answer is "yes" if you are keenly looking for it and prepared for any potential annoying problem and you can do something with it. Recent posts on Lemote BBS suggest that there are still about a score of Boxes remaining.

Recent feedback from users shows problems as follows:
1. Auto switch on without pushing the power button when power supply is given.
2. No APM is present. We have to switch it off manually by pushing the power button for 5 seconds. Moreover, sometimes we must press reset button after pressing power button to switch it on.
3. There may be waves or bands on the screen. The design is not so good that electronic flows are interfering with each other.
Command line interface is rarely failed to be shown when pushing Ctrl+Alt+F1 in Xwindows
5. If we set screensaver to "blank screen", we sometimes can't activate the machine from being locked.
6. The box may be a little longer than it should be. This leads to that some USB device like flash disks cannot be recognized. Some user also found they have to press their audio plugs hard into the Box to make them work.
7. Current 32-bit kernel only support a main memory of 256M. Debian on Lemote Box is extremly stable at 32-bit. So far as I know, no system breakdown is reported! Some ones continuously ran the box for over a month(>720 hours), it is still in good state. But if we would like to try 512M memory we have to use 64bit kernel. Recent posts on Lemote BBS shows that 64bit kernel is not very stable with 32-bit applications.
8. The fan is noisy. CPU, graphic card and FPGA share one small fan. As no APM is available, the fan always runs and it do make some noise.

To be continued.

Control your Lemote Box when you are in bed

"Tony" has release an infrared port driver on Lemote BBS for testing. The driver enable us to control our Lemote Box with a common remote control (like those of a TV set) after a brief training.

This feature of Lemote Box, together with its size and NTSC support makes it possible that the little box be a home multimedia center.

I'll try it as soon as I go home this spring festival.

All 1000 Lemote Box has been delivered to users

By Feb 7, 2007, Lemote had sent all Lemote Box to their respective users. All fans are busy running and discussing Loongson now. No one can tell how much these users will contribute to Loongson's developing but it must be considerable.

The details of Loongson 2E (Godson 2E) has been published in a recent research article: Implementing a 1GHz Four-Issue Out-of-Order Execution Microprocessor in a Standard Cell ASIC Methodology

In this paper, there is a table showing the SPEC2000 score of Loongson 2E vs PentiumIII and Pentium IV. The table is provided by "overself" on Lemote BBS.

Loongson 2E @ 1GHz achieved a peak score of 503 in both SPEC INT 2000 and SPEC FP2000 with ORC compiler, which is developed specially for Loongson.

Beryl 3D desktop on Loongson : Mission Completed!

Youbest, one of the most active Linuxers on Lemote BBS, successfully compiled and ran Beryl on Loongson Box, only two days after foxsen finished 3D driver.

Beryl is still not stable on Loongson, nevertheless, it does run.

Thanks youbest. I don't think 3D desktop can do much for our everyday work but it may attract more customers to Linux-Loongson system.
