Cellvm, a java interpreter for spu. Need help compiling it.

Stumbled across cellvm, a jamvm port for cell spus. It uses 1 spu per java software thread. Google: cellvm, some phd papers have been written about it. The copy I got had binaries, and source. Without libspe2 it complains when I try to run it, with libspe2-2.0.0 or 2.0.1, it starts, and says "B...

It seems like if NVIDIA really wanted to protect their GPU secrets, they would write a blob for ps3 Linux, everyone would install it, and lowlevel RSX research would cease.

Here is the document about how the cellbe solves the vulnerability to cold boot attacks. http://www.ibm.com/developerworks/power/library/pa-cellsecurity/ It seems like since the vram patch allows us to mount vram, why not make a patch which allows us to mount every address visible to the GPU (lv1_gp...

Micro via = multilayer motherboard Explains a lot, but reduces tracing wires to guesswork :( After reading your page mc, I looked at the plugs for the usb/wifi board, and found four of the same types of wires which also appear to "terminate". It's interesting that you found an unused port ...

Thank you for your reply, megabits, of course! meaning there is 256MB of XDR and 512MB of video ram (maybe some kind of page flipping scheme.) I have never heard of a computer which squashed all of it's usb communications into one usb channel, using a usb hub chipset. Testing my hard drive I discove...

PS3 Hardware Questions (Extra USB Port?)

Not quite sure where to put this, but here goes... First the rant: After speedtesting my usb harddrives and finding 15MB/s and 25MB/s dd to /dev/null speeds, I began looking at the motherboard pics to figure out why I wasn't getting 480Mb/s or 60MB/s from each of the 4 usb ports. After looking at th...

The firmware and harddrive are encrypted with machine specific keys. I've been trying to figure where those keys are stored. I don't think they are (permanently) in the cell chip. There is a serial number (in the cell), but it is loaded at boot as part of the "configuration ring" which the...

Nice work, With mplayer -vo, I can play a 720p wmv vid (ARGB -> YV12) without skipping, but my video shows up distorted, and covered with green. Also the program robs my framebuffer (I have to give reboot command) If you think this is a bug issue, I would be glad to provide the console info (doesn't...

It seems that if Sony wanted to deter people from using Linux to boot their game ISO's they should simply make their games use every core of the cell processor, even for padding operations, just so the games will skip and buck if anything else is running on the system (Linux, RSX access workaround, ...

Troll and Triangle are now working :-D I found the new (different) mknods.sh in the init directory, and ran it, worked beautiful. Thanks for the n00b support IronPeter, I'm anxious to see the New Year's version. It would be cool if the demo moved, and made the rsx draw it's max number of triangles p...

It compiles on the patched kernel but I still can't see the triangle. It screws up the screen for a second if using ps3videomode -v 3 or ps3videomode -v 4 I tinkered with ps3gpu.c line 560 width and height, trying 1280x720 and 1136x644.

Forgive me if this is n00bish, but I believe the hypervisor runs on the illusive 7th spe. But I remember reading that the spe's can't access memory. Doesn't that mean that they can't access the devices without asking the ppe? If so, then the hypervisor must either: 1. Be two pieces, a kernel which r...

Excellent work! I have gotten the patch to work and put ps3X in the startx script, and got multiple copys of "mplayer -vo x11" to play translucent on top of each other (cpu hog!?) (have not patched mplayer yet) When I run ./ps3gpu I get: vram 264241152 fifo 65536 ctrl 4096 Segmentation Fau...

swap over network

I have tried swapping over network, First I made a ramdisk on my winblows box, then I shared it using smb, and mounted the smb share to /ramdisk then in /ramdisk I made a swap file, and prepped it for swap, but when I used the swapon command, it refused. So i tried nfs, same result. I have since fou...
