Back on Topic. I had an interesting though unproductive conversation with someone who claims to have access to LV1 source, and the conversation turned to this issue: ... <Strontium> Understanding what every parameter of every HV function does without documentation from Sony, that is the hard part. <...

The Forrox Author should have no credibility whatsoever. His stuff is the grandfather of all PS3 fakes. Nothing was adjusted to stop Ferrox working, because he never had anything working in the first place. What nonsense crap he speaks now. HV privileges were adjusted in 1.6, what a bunch of crap. T...

Wouldn't it be more efficient just to code the shaders in SPU assembler and/or C and just define a shader dynamic loader and shader standard interface (basically a dynamic SPU shader plugin, loaded and unloaded on the fly), and able to run multiple shaders across multiple SPU's. The work then is def...

Oh, is that all. There is another way to win. Play somewhere that has NO laws. Thats my choice. To sue someone you have to be at least able to point to an ACT of law that is alleged to be transgressed. Where I live, No Copyright Law, No Patent Law and No Trademark law. Of any sort, so, I don't see h...

Can you be specific about what recent threats?

What PS3 TEST hardware? If you are talking about the offical Developer machines, the answer is Yes. If you are talking about normal ps3's, you can use GDB to debug any code you can run under linux.

Disregard my previous post, I got it working now. I am working on getting the second thread running, which I now have achieved (plus some other minor optimisations). Here is my code in progress in case anyone else wants the second thread. (This is just the boot code, you need to provide your own sec...

Hi,

I am working on a modification to your otheros demo.

I am getting a black screen at start, I have obviously broken something.

Any tips on what you did to debug it? Or did you just Burn and Learn? I can't output debug info to the screen because it isn't even getting that far.

I just tried to run the ELF in your demo and it just segfaults? Any tricks to running that? I am running it under kboot.

I am about to try and install is as an otheros to see what happens.

What's your opinion about this idea? My opinion is simple: you will probably never find any such thing that is accessible when not in hypervisor mode. Here is the probable way hypervisor works: 1. the processor is either in hypervisor mode or not 2. there are different memory mappings with differen...

Excellent Job.

what about this? http://git.kernel.org/?p=linux/kernel/git/geoff/ps3-linux.git;a=blob;f=drivers/net/gelic_wireless.c;h=4f30b3d7b28f18b4bba2b35abaf280cebe873f9e;hb=766339edf275f63edcb116c5e262a4efa1574942 Yep, that looks like it. For the interested, the whole patch can be found at: http://git.kernel...

Isn't RSX the display driver-doesn't that mean we can't get proper output unless it goes through that? And sure the cell can decode the data, but don't we need RSX to display the data properly? Sorry if I'm being dumb. Linux under the PS3 is quite capable of displaying 1920x1080px60Hz now. The issu...

I searched the source on kernel.org and there are no updates, apart from config changes, to support WiFi. And YellowDog had this to say on the matter yesterday: We're still shipping 2.6.16 for PS3s, although there is now a new version with wireless capabilities. This kernel is only available on YDL....

Yep, unfortunately its just WiFi. And in a weird twist its either WiFi or Wired, but not both at the same time (both are eth0)....

Thanks to those who replied.

I'm all sorted now.

Cheers.

topic says it all, i am trying to get a copy of the V1.5 ps3update.pup, as I want to update a PS3 I have here to that version, BUT not later version. If anyone can help, please PM me.

I did a net search, but no luck tracking it down.

Thanks,

Obviously no sane person would update their GameOS on his advice

And why would a sane person not update?[/quote]

Well, Sony have a track record of taking features away from the homebrew scene in firmware releases, not giving them more. So if you upgrade, you may be screwing yourself.

Could anyone doing any SPU programming try and DMA data from an SPU to GPU memory and benchmark that?? The reason why I ask is the SPU's are supposed to be tuned to do multimedia type operations. It would be really stupid if they had crap DMA write and read performance to GPU memory. I haven't done ...

Hi, Title says it all, myself and at least one other I know are constantly getting errors from the wiki. I know the wiki part isn't managed by the main team here, but it really needs to be fixed. Its so bad that I have been seriously thinking about starting a new site just to host a new version of t...

So this mean the hypervisor function only return the pointer of DDR address without any verification or standard malloc process. I think this is a serious bugs. It isn't a malloc type function. Memory must be requested in 1MB blocks. It is really just a function that maps the GPU memory into the Li...

Problem Solved (i think). The first n words keep getting over-written. Absolutely certainly by the screen refresh blit. MY PS3 is running in PAL* mode (6) which has a frame buffer of 720*576*4 bytes = 1,658,880 bytes, double buffered = 3,317,760 bytes. My system can not verify memory written to the ...

I'm seeing it reset to some other value after 15ms or so. Definitely weird. 15 ms looks suspiciously close to the framerate. BTW doesn't the 256 MB area also contains GPU IO address space? It doesn't appear to no. See: http://wiki.ps2dev.org/ps3:hypervisor:lv1_gpu_device_map Audio registers are in ...

Not exhaustively. I agree it needs more testing. I did see some strange things, but mostly to do with 8 & 16 bit operations. I will do more testing. My accesses are all 64-bit. There seems to be some (as a guess) caching issues that might need to be addressed. What I did find however, is if I a...

StrontiumDog, how much have you tested this? Not exhaustively. I agree it needs more testing. I did see some strange things, but mostly to do with 8 & 16 bit operations. I will do more testing. It doesn't seem to work very well for me. I wrote a driver to expose the extra ram as a MTD block dev...

Hi All, Early fruit of the Hypervisor documentation project is available in: http://wiki.ps2dev.org/ps3:hypervisor:lv1_gpu_memory_allocate Basically up to 252MB of memory can be allocated for use by an app from the DDR connected to the RSX. Caveats : It only appears to like 64bit or 32bit accesses. ...

Hello Admins,

I am having problems with the Wiki I can not resolve. I need the assistance of an Admin. Can one PM me please so I can get this resolved? I can't use the Wiki at all at the moment.

Thanks in advance,
