Doubting what a hacker can do based on reading about the system is so funny. Many developers here have done more than just "read about" the system. But even just with the literature, we can have a pretty good idea of what he can do. He's glitched something either on the FlexIO bus, during...

How can you claim that the Slim is vulnerable to this when it doesn't have OtherOS? Half right, half wrong. Because OtherOS just give you a platform to "Run a Code" (or the right term is, inject some code on the memory space). But the exploit is based on the hole of non-ECC RAM. So of cou...

You didn't debug your april fools before you post it?
Big mistake~~

I would like to say, your information is not enough.

What do you mean "not working"? It cannot detect the pad or it cannot init after you run the init program? If it cannot detect the pad, it should be nothing you can do. If your case is, nothing happen after you run the init program, I found a source code of initiating the sixaxis. It shoul...

Does this matter? ps3fb: Update for firmware 2.10 As of PS3 firmware version 2.10, the GPU command buffer size must be at least 2 MiB large. Since we use only a small part of the GPU command buffer and don't want to waste precious XDR memory, move the GPU command buffer back to the start of the XDR ...

use SVN to get the latest toolchain~~ the latest version is Rev 2320 - 2007-10-01 03:03:50 +1000 (Mon, 01 Oct 2007) I'm using ubuntu 7.10 rc and rebuild the toolchain almost ten times these few days, no problem at all. Is there anybody building toolchian in Ubuntu and met this problem. Please tell m...

Even you set your resolution of your PS3 to 1366x768, doesnt mean that it can display all content, since most of the LCDTV will overscan the input source. So you better first try to use computer output 768 source to your LCDTV to test your LCD support it or not.

I can tell you that, the file is signed. So even you know the format, you can modify it in your own way~

Anyway, happy hacking~

The latest ADDOn of CELL now having a document called "Cell Programming Primer", which have a section contain a sample program of rgb2y using SPE (Chapter 3 Basics of SPE Programming). For those who want to learn more about how to use SPE, check that out and you will find it is really info...

I think it has some checking process before wireless lan modules activate. Since 20g verison doesnt has the WLAN hareware. May be it is done by hypervisor function.

Why people always think about RSX? Does it mean to you, or you want it because you dont have it?

Does RSX have any hardware acceleration for MP4 decoding? I think CELL has enough power for decoding MP4, the only matters are about HDCP and AACS.

All the stuff about lv1 call is here / include / asm-powerpc / lv1call.h

And you need to read other file to find how to use those call.
Happy hacking~

Anyway, does the lv1 call limited to 256?

Somethings about storage is changed. Take a look here

PS3 ROM Storage?
PS3 FLASH ROM Storage?
What does it refer to? Of course not the firmware~

Oh, yes. After read your post I do some research. That "other os area" should refer to the kboot (which is otheros.bld). Thanks~ I believe "OtherOS area" just refers to the 4MB block of flash used to store the kernel and boot parameters (compression, boot flag, etc). You can acce...

From the source of kernel , os-area.c , I know that the "OtherOS" will copy into the memory area. So my question is, does anyone try to dump it from ram? Does it encrypted? Does it refer to the otheros.self? /** * struct saved_params - Static working copies of data from the 'Other OS' area...

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. And we know that linux kernel allocated some memory for FB when it start, why the function still return the address which overlaped with th...

But I think GPU wont use whole 256mb ram for bitblt process. The ram for framebuffer should be fixed allocate when the kenrel is started. The point of function malloc should allocate some free memory from the RAM space. Also if those ram we allocated is overwrited by framebuffer, I think the value s...

Just a OT notes, there are different file format with filename extension PKG. For example , F@H file from the net should be a package file (with a PKG header inside the file). And from the firmware, some files like "MULTI_CARD_FIRMWARE.pkg", header is SCE. For those file which is encrypted...

Really good one !!

Anyway, if my memory is correct, the PPU <-> GPU Ram access is very slow compare to PPU <-> Main Ram (And now with a hypervisor process between). So how useful about those extra RAM is a question. May be someone can write a benchmark program about that?

I can give you some interesting info about otheros.self If you look for hex value "BC3F7A48AF45EF283A0598103F", you will find 3 sections which having same values for some bytes (hex values of above is the start of the section), and it look like a header. What I guess about it is, 3 spe elf...

Build the binutils with CELL SDK 2.1 and you get ppu-readelf and spu-readelf


The follow has some basic inform about CESOF
http://www.embedded.com/showArticle.jht ... =188101999

As I mention before, the ELF file used in Ps3 linux contain more sections than a standard ELF file in common linux, you need to read the CEBA handbook to look for the new section info.

you can try readelf to decode the otheros.self without the "SCE header". I dont have ppu-self or latest binutils , but my old readelf can give some correction information about the elf file (for examples, 64bit , big-endine, etc.) and these match the info from CEBA handbook. Of course some...

Yes, it is a sce + elf file otheros.self <- "self" mean sce and elf if you remove the sce header, the remain is a elf file. You can use readelf to read some headers information. (You must use ppu-readelf or spu-readelf to get the correct info) Ps3 introduction some new sections to combine ...

Folding@ team already explained clearly the pros and cons of CELL with Folding@Home. In my opinion, you can only take advantage if your code is best fit with the SPU and vector programming. Otherwise CELL is only a G5 PowerPC processor. So I think directly compare CELL with x86 based CPU is meaningl...

Since the linux version of VLC only using plain linux structure and didnt use any CELL technology. It should be used the PPU of the Cell only. (or part of the spu, whatever) If anyone port the libmpeg2 using spe, I think the performent will be better. (Just like you play the movie in the xmb) Hi. I ...

In case you are interested in develop ps3/cell application

http://cag.csail.mit.edu/ps3/lectures.shtml

This site is from MIT and contain some basic information about how to write program for cell (actually the topic is about parallel computing, but they use ps3/cell as a target machine)

Good suggestion. Everyone have PSPSDK source , why dont you patch it and share it with us? While using pspdebugprintf, it has the tab size set to 5. It would be nice to have a command that allows you to set the tab size yourself without having to recompile the library. It should be a really easy sug...

Again , make sure you have the lateset toolchain script. And follow the readme from the toolchain.
