147w 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 http://ps3wiki.lan.st/index.php/Custom_Firmware_with_OtherOS%2B%2B: 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

I'm not sure how this graf's driver is implemented as I've not had a chance to look at it yet, but certainly it's quite likely to be very slow accessing video memory as the CPU read speed to VRAM is very slow. You can read more about it here: noeman.org/gsm/sony/10307-rumor-ps3-slow-broken.html (where local memory means local to the GPU).
The PS3 swap driver for OtherOS gets around this by using the RSX to transfer data between main RAM and VRAM because the RSX has pretty good access speeds to both. I'm guessing this should be trivial to port to asbestos, and possibly this is what's being used anyway.
Hey guys, I'm sorry for the uber noob question but how do I go about getting the new drivers installed. I'm running Ubuntu and I have to say, it runs like crap. I've searched on getting it running great but I can't find anything definitive. What I need is how to get ubu running better as well as how to install the new drivers! thanks in advance!!
