when you boot linux, why does pdaXrom-ng leave the controller on? There isn't a way to handoff the controller to the flavor of linux that you boot is there? I think you are talking about the pdaXrom-ng - based bootloader. pdaXrom-ng also is a full distribution to be used for liveCD's or bootable US...

the PS3 wireless joystick driver Sashz uses in pdaXrom-ng is derived from Jim's code, and implements a Linux Joystick device in /dev/js[0-]. There should be a way to modify it to turn the controller off after a certain period of inactivity. It sets up the LEDs correctly and does not need the bluez d...

Hi, just to inform the sdlmame download server messes up versions. The script actually requests to download version 0.133 but the server sends 0.134 (0.133 is not available anymore). Of course, the patches are incompatible without (trivial) changes, but the compilation stops with an error about miss...

Very cool stuff. Nice work, sashz. Seems it doesn't use the SPU-accelerated framebuffer driver in SDL 1.2. Not really a problem though. As wiki.pdaxrom.org/downloads is currentlt not working, I tried to make the mame iso myself. But the compile process stops when building SDL: powerpc-ps3-linux-gcc ...

I included your arguments in my blog article. Please feel free to use it as a starting point or not.

Maybe some arguments are missing, but for me the most important is there: This was an arbitrary decision, it is felt like a betrayal, and it will encourage hacking.

I managed to build an ISO image from the svn sources. However, the resulting image doesn't seem to boot on my ps3 (euro 60 GB model). After selecting the liveCD from the boot menu, the screen goes black and nothing happens.

For those who think they would be luckier than me, the files are here.

same for me.

The sourceforge svn is still reachable. However, some of the build scripts rely on files hosted on pdaxrom.org, so one cannot build a bootloader from the svn sources aswell.

I'll try to maintain a mirror site once the pdaxrom.org server gets alive again.

you might be even more efficient if you work on quads rather than stripes as you'll have to process less triangles per quad than per stripe.

graphiccards have a WAY less texture cache than the spu has local store, you dont need the whole texture in it to rasterize. Well in my personal rasterizer work, I have taken advantage of that additional SPE memory, allowing to draw on much bigger zones than 8x8 squares at once. My test code can dr...

sorry if my English lacks accuracy. for me a "rasterizer" is everything required to draw triangles on a framebuffer. Of course, you don't need textures to be able to draw triangles, but in my mind, textures are part of the job. I hope Miya will find good ideas and a lot of motivation to ge...

J.F., I think texture mapping brings much more trouble than you think. Textures have to be loaded into SPE memory, and in the case of several textures to be mapped into different triangles, DMA transfers would certainly become a serious bottleneck. I have also written test rasterizer routines, and I...

I have had a quick look at the code, the rasterizer merely displays single-coloured triangles, and the code is supposed to be fast.

In fact, as the comments are in Japanese, I may have missed more features.

I compiled SDL with Cell support (following instructions from the README.PS3 file).

Then, I compiled mplayer with SDL support.

And then, playing videos (using options : -vo sdl) does not make use of spu's at all, according to spu-top.

I tested in X, and in fullscreen framebuffer mode.
