200w ago - Following up on his previous update, over the weekend PlayStation 3 hacker Graf Chokolo has released his PS3 Linux 2.6 Kernel and began documenting his PS3 CFW Custom Firmware with OtherOS++ Project.

His new PlayStation 3 Linux Kernel includes a new HDD, FLASH, VFLASH and RAM drivers for PS3 and AsbestOS users can use the drivers as well.

To quote: The repository which is based on Linux 2.6 kernel, has several wicked stuff in it especially graf_chokolo’s ram block device. As kmeaw said; “It can read/write anything in PS3 RAM, and very useful for HV hacking”

You can read below the commits done to his version of Linux kernel.

  • Added support of several storage regions to PS3 storage library
  • Improved PS3 disk block device driver
  • New drivers for PS3 NOR and 3 RAM misc driver for full access to HV memory
  • Added new HV calls
  • Added extra debug messages for SPU isolation

Finally, from [Register or Login to view links] PS3 CFW Custom Firmware with OtherOS++

  • First we need a custom Hypervisor (lv1.self) with OtherOS++ support and other nice features like full access to HV services :-) (working on it)
  • Second, we need a program like otheros.self which will resize VFLASH region and store there petitboot
  • Third, we need a GameOS program/XMB plugin which will trigger OtherOS++ boot after GameOS reboot by setting a flag on the 5th VFLASH region

Nice, but asbestos can already boot Linux from the internal HDD using the linux.img on the root of the filesystem...

Making a new firmware and booting it from vflash seems a bit OTT compared to that unless it has more features or is a bit quicker or something?

I'd rather mount the ps3 filesystem in Linux and boot from that rather than partitioning, if only someone could make a way of decrypting the ps3 filesystem...

as for the kernel , full access to the GFX ram? does that mean we can actually use the video ram as ram instead of swap space now? if so does someone have a compiled kernel?

The development of Linux' return on PS3 has been developing a good deal last two weeks from AsbestOS from 1.5 to 3.0 version and loading through USB media, to this very intering (and desired) development to give it full OtherOS back.

Very much anticipating this

Wow, this seems VERY promising. I like the idea of having petitboot, which will simplify the switch between GameOS and OtherOS. All the work graf_chokolo put on HV hacking is awesome! Finally an unrestricted system! Looking forward to this. We will probably be able to triple-boot soon; imagine GameOS fw.355 + GameOS fw.356 + Ubuntu = freaking sweet!
