Fedora 7 should be using hal to open the file manager when you insert a USB stick or a dvd, if not, put: '/dev/scd0 /mnt/dvd auto noauto,ro,user' in /etc/fstab and create a device shortcut to the dvd on the desktop which you can open anytime you insert a dvd. I'm not sure how exactly to create the s...

Software Open GL accelleration on cell would be a nice feature not only for the ps3 but also for future cell compatible or cell platforms. Even as a proof of consept it would be great to have. I actually think there might be a closed source implementation out there. Perhaps something like Mesa itse...

The reason I said "Putting a digital oscilloscope to the buses in the ps3 during startup will get you further.." was because I knew about the xbox hack. :) Stupid encryption. Trying to understand what ralferoo said, the SPU would still have to be initialized by software to go into the isol...

It's insane to even try to "attack hardware" by trying to look at it through a really powerful microscope. What're you going to do, take pictures of half a billion transistors and try to put it all together? Regardless, cryptographic keys aren't stored there, and you'd have better luck try...

Is the hypervisor code running on an SPE? Reading some of the CELL docs , they mention a state where one of the SPE's can be made to go into a secure mode, none of it's local stores/registers are accessible except a small part so it can still communicate with the PPE. Since there are are only 6 SPE'...

The gcc port for SPEs (c, c++) will be included in 4.3, but some distributions ( OpenSUSE , Ubuntu ) already have a separate package. Not sure how Ubuntu's version is 4.1.1, since the CELL was barely even out when GCC 4.1.1 came out. OpenSUSE shows the spu-gcc binary was built from svn code in April...

As long as compression+decompression of a page is faster than a seek on the swap HD block device, compression is a performance gain. Whether you keep the compressed data in RAM or write to swap is secondary. The problem seems to be in finding the right things to compress with the right algorithm, st...
