<flamebait>C++ adds nothing to C except a vehicle to generate bloat more quickly.</flamebait> Write in C . LOL. I think we could have a nice discussion about this over a beer or two, and I wholeheartedly disagree with that ;-). While C++ indeed does add a vehicle with which you can add quite some b...

100+ Views... Someone answer. I want to start programing. Maybe it's because your question cannot be answered conclusively. It depends on what you want to do. If you just want to hack around a bit for fun, and not want to start some serious project I'd start with plain C. For larger projects C++ mi...

Test is very simple. Try in the kernel mode u64 a = 0, b = 0; lv1_gpu_memory_allocate( 0, 0, 0, 0, 0, &a, &b ); printk( "%8x %8x %8x %8x \n", (u32)a, (u32)(a>>32), (u32)b, (u32)(b>>32) ); It is better to try that call before any RSX stuff ( for example in the ps3fb.c ). Peter. Wha...

I had the ps3rsx module working on Fedora 7, but after updating my PS3 firmware from 2.01 to 2.1, dmesg says: [snip] I normally switch between YDL 5.0.1 on my internal drive and Fedora 7 on an 8 GB USB flash drive by changing bootloaders ... The one from the YDL 5.0.1 CD still works fine, but the o...

2.10 ends RSX ! after updateing to 2.10 linux do not boot ! it starts the kboot promt I hit enter linux boots, screen goes blank, stays that way for 10 min , after some time the sceen blanks , and reblanks and so on , after some time , but noting more. I have had the same experience with my Fedora ...

Just google for things like this, this is all pretty basic stuff...

Tnx, fixed it.

Well, when you consider the only other console that has more than about 88 MB of memory (afaik) is the 360, I doubt memory's going to be much of an issue, since I doubt the PS3 is going to be able to emulate the 360 no matter how much memory the PS3 has. Also don't forget the PS3 has another 256MB ...

Anybody know why mesa/X haven't been compiled on the spe's yet? Though Mesa's successor is being ported: http://forums.ps2dev.org/viewtopic.php?t=9475&start=0&postdays=0&postorder=asc Because it's a shitload of work and not too many people know how to do it properly. Also, to you and to...

Yes

Hi guys. Great work with PS3 accelerated driver. I wonder, if you can build an ubuntu installation package for newer kernel (2.6.23-rc7), so that both PS3 annoyances are resolved - broken wifi and fast video :) I will prepare a new package related to the 2.6.23-rc7 kernel tomorrow. I do not have mu...

Status report: 2.6.23-rc7 (my kernel version, taken from forum thread where guys managed to fix wireless in it) and 2.6.23 (supplied by d-range) don't go togehter too well, because of different kernel names. If there's a way to override it, lemme know, but insmod doesn't like me so far... Let me gu...

Is it the hard disk, or the controller, or the fact that it goes through PIO and you can't change it? Likely a combination of these, I didn't know it didn't do DMA, that might explain a lot. But disk performance is not really an issue if you want to build a media center, emulator, etc. For desktop ...

Yea, i got multiboot. Will try that around 5 pm GMT :) Will post results here. Now...how do we get out of PS3's sandbox. I seriously doubt that with PS3 specs, the performance of 158 BogoMIPS and `terminal` starting for 3 seconds is what this box can do. Or is it just my weird installation?... The ...

Heya! Saw your post when was rushing off to work. I wonder what i must replace in kboot.conf to load your driver for .23 kernel, and existing driver for .22 kernel. It's been ages since i last played with linux. I'll figure that out, and i'll try it as soon as i get home tonight. If you already hav...

Hi guys. Great work with PS3 accelerated driver. I wonder, if you can build an ubuntu installation package for newer kernel (2.6.23-rc7), so that both PS3 annoyances are resolved - broken wifi and fast video :) Maybe you can check the module I built on Gentoo, I'd be interested to know if it loads....

d-range, Thanks for the detailed instructions! One small question though, are you running a 32 bit or 64 bit Userland? Can you run a 32 bit UL with a 64 bit kernel? Again, thanks for the hard work and detailed instructions. Audball I'm running 32-bit userland, it saves some RAM. So yes you can. 64-...

I finally managed to fix my hosed gentoo setup and get it to boot the custom kernel I built to compile the ps3rsx module against. Turned out that for some obscure reason the bootable flag of the /dev/ps3da1 partition was cleared. Anyway, I now have a working ps3rsx and xf86-ps3-video setup including...

I was planning to write a source-level Gentoo ebuild for ps3rsx, but after mucking around a bit to do a manual install first I think this is not going to work. The stock Gentoo kernel kernel doesn't work on the PS3, and the gentoo-ps3 kernel sources cannot be installed automatically. Things would ge...

A gentoo ebuild would be GREAT! even if it's not accepted into portage.

Ok, there's at least 1 person interested so I'll have a go at it tomorrow, should be a piece of cake, though I know absolutely nothing about Python ;)

If there are people using stock distribution kernels and have packaging skills, a nice contribution would be a .rpm or .deb of the kernel module for all other users of the same distribution out there. I might be able to write a gentoo ebuild this weekend if anyone is interested in that. I want to c...

d-range, I am professional PC-game developer.. That explains a lot ;-). Can't wait to see what you come up with. I used to follow the demoscene a bit a few years back, also went to a demoparty twice. Back then it was already amazing the stuff some ppl did with the xbox 1, or even more impressive th...

Glaurung, I'll try to resolve "busy" issue. It is hard to tweak existing ps3fb. I am very happy with ps3rsx progress. Of course, there are many bugs, but the project seems to be successful. My roadmap is to clenup and refactor it to the New Year. And after that expose large 3D demo with h...

Its an interesting idea but you will still end up with (HW assisted) indirect rendering. It's faster than software rendering, but don't expect performance anywhere near what direct rendering would achieve. For real-time interactive applications you also have to factor in input delay, network latency...

you have 24 GB/s to go on there.. in comparison a YUV420 frame is 3.1MB in 1080p so even if you split it and over dma so that you transfer 4 times as much data as needed its still fine.. 24GB/s bandwidth that is, but bandwidth is not the problem. You still need to feed everything to the SPE's in ti...

Provided the cell (spe's) do both inter and intra frame decoding the ppc processor is left with the task of decoding the bitstream more or less. hopefully that will be enough If you build it efficiently, it will be. You will want to limit ppu<->ram<->spu traffic and data dependencies as much as pos...

And we have started looking into ways of accelerating the mpeg2 mpeg4 and h264 decoding using existing programs such as ffmpeg. There is also allways room for more people :) I'm still looking into the video decoding stuff, but I more or less scaled down my focus from h264 to mpeg1/2, as there is lo...

libps3rsx is for small free-to-play-games. And I very glad to hear from you that OpenGL is bad platform for these games. I beg to differ. There is really nothing 'bad' about OpenGL as a platform for anything 3D-related, if I'm correctly you even program GameOS games through the OpenGL API. I think ...

androvsky, PC needs high level interfaces like OpenGL. And OpenGL drivers from NVidia are very stable and well supported. Of course, you can run something like nv40_demo by Nouveau team on your NV40 : http://nouveau.cvs.sourceforge.net/nouveau/nv40_demo/ But you will not be able to ship your produc...

I've been following this thread for a while, great stuff by everyone involved, keep it up! I've just started a 'little' pet project for a H.264 decoder specifically written for the Cell CPU, from scratch and thus not based on the ffmpeg decoder which is hard to parallelize optimally. It's still at t...
