Raspberry Pi

category: code [glöplog]
As a desktop OS, of course it is limited by memory and CPU.

They were claiming the GPU is more power than the one in an iPhone 4S and 'expected' it to be faster than tegra 2. That, combined with the HDMI output is what piqued my interest.

Writing against a fixed speed open platform using code that with some #ifdefs for window setup, and shader tweaks, which can also run on modern style desktop gl sounds like a good way to scale things for low powered accelerated platforms.

In reality, so far, the Raspberry Pi seems to have been used more as host for controlling real world hardware, and the cases that have touched the GPU properly are few and far between. Given the cost its not quite how I expected things to be. I guess if its possible to shock and awe with it, then it could attract people.

There are toolchains out there now to compile and remote debug from visual studio.

I'm tempted to "just make a demo for it", but I'm having enough trouble finding time to work on stuff for windows at the moment. (autumn/winter is coming though..)

Since the information in this thread regarding the GPU driver is quite dated - well, it's from late 2012 - I thought I should post the update from February 2014 for the sake of completeness:

Doesn't seem like a lot has happened apart from that guy getting $10,000 for getting Quake III going without using the blob.

A search for demoscene on their blog yields no results. demo yields not much either.

Why the hell would you expect that to be an indicator of anything? Do you judge the level of activity of the Windows scene by looking for mentions of 'demoscene' on microsoft.com?

Because downplaying is an indicator of superiority?

I was curious because I think some demoscene exposure into the rpi community would be good outreach. I was just idly wondering if they had covered any efforts on the Pi (like your own for example).

I do remember reading posts on their forum a long time ago that the rpi team are aware of, know people in, and got the impression they would welcome scene activity with open arms.

One more option to get a bit more speed is to overclock the RAM and the CPU. 800 is safe, 900 seems to work fine on many boards.

Um, now I maybe mistaken but 2012 they released a GPU driver which can hardly be called so.

This year however we have this, which is what some people asked for in the first place:

Earlier today, Broadcom announced the release of full documentation for the VideoCore IV graphics core, and a complete source release of the graphics stack under a 3-clause BSD license.


Sure, that was half a year ago, but as I said, I added this for completeness' sake, and to update the posts from 2012.

As for the scene: That certainly is not a focus of the RPi foundation. I can imagine a good demo to receive their attention.

Indeed, they really went for the open-docs and open-source drivers this time, really cool.
