Let's cross fingers but we can't be sure about what Sony has in mind... So, in case it turns into a bloody war, here are the links to 2.01 fw (lastest fw known to allow 70% of RSX control under Linux) http://dus01.ps3.update.playstation.net/update/ps3/image/us/2007_1120_1d8e69249aa1a5593307cf7d8ca8a...

Sure, boxbuilder, the more tutorial we get, the merrier Xmas will be!

Just don't upgrade fw to 2.10 now...

Message to all (nasty) hackers : Need to design a downgrade procedure...

Thanks a lot Glaurung! More people will be able to play with RSX now!

Currently PS3 is the only console unharmed by piracy. For a simple reason, hacking pressure is very low. If they don't let us play with RSX and close the hole hacking pressure will rocket up. Also it's obvious we won't get the caches of TILES, so we won't compete with GameOS games performances (we w...

I failed. I applied same change to av.c and proto.h as usual (see post "otheros demo 1080i patch"). In demo.c I've tried BB=2 (I was probably wrong to assume it was the number of buffers like in otheros demo 1.0), but I've tried also BB=24 like you said with DDR_SIZE=48Mb in fb.c, but it h...

Thx for the hint. That will help me. Hanging in HD mode hurts since you have to reinitialize bios and play with cables each time to see something again in LD... But it's ok, I'm over motivated (but I don't have much time to succeed, I cross fingers) ! EDIT: Strange, the reset didn't make my PS3 lose...

I'm lacking free time (end of fiscal year, insane work to do, even on weekends). Today I've just managed to keep some free time for trying to apply the 1080i patch to marcus other_os demo 1.1. I'm trying that at the moment.

Hehe... You are too fast for us, you know...

Great! You rule!

Wonderful! Thanks a lot!

Magnificent!

- You write ps_texture.cg (theoretical source of nv_shader.h content): struct myVertexOutput { float2 texture_coords : TEXCOORD0; }; float4 main(myVertexOutput I, uniform sampler2D colorMap):COLOR { return tex2D(colorMap, I.texture_c...

- Get cgc.exe from NVidia SDK 9.5 (free) - Create vs_texture.cg (theoretical source of nv_shader.h content) : struct myVertexInput{ float4 position : POSITION; float4 texcoord0 : TEXCOORD0; float4 texcoord1 : TEXCOORD1; }; struct myVertexOutput{ flo...

Grats Glaurung! It's fantastic!

emoon, I think that would help IronPeter if you just publish (or let him look at) your partial work (even if nothing works). There is the possibility that the current design in progress by IronPeter can link itself somehow later to EITHER Linux or ps3link (at some intermediate API level). We shouldn...

I wonder what happened to the ps3link project.
Source directory is still empty...
Anybody knows?
It would be the natural competitor of your Linux LiveCD distro idea.
(Boot OtherOS ps3link, upload homebrew game from PC, play it)

If you can post basic shaders assembler source and header, along with binary result, I'm sure many will be happy to help coding the assembler. Let's start with basic shaders and see what we obtain. Just create a new thread named "FP/VP assembler project", and let's start.

Iron Peter, do you feel a high level language is missing out there? I mean one, that is well adapted to describe what will become both NV_FRAGMENT/VERTEX_PROGRAM binary micro-code and the code on CPU (or SPU) side that synchronizes well with it. Feel free to keep on being our locomotive and just des...

Well if spu-based and rsx-based solutions could be compatible (at some high level entry points) that would be a safety belt in case Sony roars... Unfortunately there is an ugly policy change in the highest ranks of Sony. I have the strong feeling big bosses there just got incredibly jealous of Ninte...

Thanks

Grats on the index buffer breakthrough! Can't help now because I'm lacking free time, but I will just describe how native shader assembly could be done for nv2A, for xbox1 : - First the shader model must be identified. For nv2A it's SM 1.1 - Cgc.exe (from NVidia SDK 9.5) translates high level text l...

Let's dream again, about... TILE... For those who haven't take a close look inside pbkit source (plenty of comments there), here is the explanation of the TILE concept : When you declare a TILE, you declare a memory area. Its most spectacular usage is for the depth stencil buffer. On nv20 you could ...

I've forwarded your request. Keep faith.

Nouveau project leader answered my help request. Here is his reply :
Feel free to explore these dumps :
http://people.freedesktop.org/~kmeyer/renouveau_dumps/
Try to find the "test display_list" which uses index buffers

(I don't know these dumps, I can't give you more details)

I'm speechless... It's heaven. Thanks a lot IronPeter! For index buffer, I don't know well enough nv40 yet, but you can see how it is done in nv20 by looking at pbkit Demo 04. There are constants in the source to define in order to have rendering by index buffer instead of vertex buffer. Also by loo...

Don't worry we will find a way, even if it takes months to find it. If we can have vertex buffers running, that will be already heaven. I have the feeling the interrupt handler is the key. Since it's used to report gpu errors, I don't think it doesn't exist in HV, and I'm pretty sure, Sony engineers...

I would like to talk about performance (because we talk about shaders). There are persistent rumours that claim that the 360 Xenos is faster than RSX. Of course, now, we are getting closer to the answer, since we will be able to count the number of vertex per frame we can enqueue (when vertex buffer...

I will try to give a hand with 4). The idea is to do something similar to function pcode2mcode in pbkit. It translates standard shaders written in pseudo code into native code. That way public compiler Cg.exe could be used and you just include the binary (pseudo code) result in your code, then funct...

Fantastic! You did it! Shaders running on PS3!!! Thx IronPeter!
Time to adapt this for other os demo... (come here free time!)
PS3 owners who love coding will have wonderful Xmas holidays!

(beware to next firmware upgrade though...)

There is, technically, a way to branch to sub fifo buffers (of any size). But that implies to know what services the interrupt handler associated to the GPU interrupt can do. Once again, I will describe what happens with nv2A on xbox 1. In the main fifo sequence you just put a fire interrupt command...

Thx for finding the solution. Keep on the good work!
