September 21, 2010 // 4:54 am - Following up on his previous work, today AerialX Tweeted that the beginnings of a PS3 LV2 Userland (GameOS) patch framework dubbed Kammy are available for PSGroove linked above at Github or directly below.

Download: Kammy Userland PS3 LV2 GameOS Patches for PSGroove

To quote: Kammy is a system for loading patches to lv2 (PlayStation 3's Game OS) from a user application, using PSGroove or any other implementation of the exploit that adds the peek/poke syscalls. Kammy was inspired by Treeki's Nintendo Wii game patching system, Kamek.

Building
Building Kammy requires three different gcc compiler toolchains.

•gcc: A normal host gcc is required to build the raw2h application.
•ppu-lv2-gcc: Used to compile the loader, only available from Sony.
•ppu-gcc, ppu-binutils: A version of gcc that will compile 64bit PowerPC instructions is required to build the patches. Linux packages can be found on BSC.es. (note: ppu-lv2-gcc may suffice for this, untested)
•xxd: Creating patch bin files requires the xxd tool to be installed.
With these dependencies installed, you can build Kammy by simply cd'ing to the loader directory and running:

make clean
make

Usage
Kammy must be used with a payload that supports poke/peek. This includes PSGroove and most of its forks - including my own - among others. To apply a Kammy patch, a loader application must be started on the PS3. This is usually done from XMB from an installed package, or from USB using my PSGroove fork's apploader payload.

Customizing
Kammy is made up of two main components:

•lv2: This folder contains the lv2 patches to be built. See the main kammy patch for an example. It is up to the patch to apply any hooks needed to lv2.
•libkammy: This is the basic library that handles the loading of Kammy patches.
The loader/ folder contains an example of using libkammy to load a patch from the lv2 folder.

Notes
Internally, Kammy obliderates syscalls 8 and 9, so try not to run it with payloads that provide those syscalls (like my debug payload).

The built in FTP Server is to buggy to implement in the background, it would either crash the system or crash itself with no way to restart it. Besides do you really want to play a game with your uploading a game? that will cause the files to become more fragmented.

The PS3 isn't great at multitasking different programs at once. Look how long it took just to get some basic in-game XMB functions.

With custom firmware it should be possible but it might cause performance issues.

This would obviously be very nice for internal HDD users, as it would allow you to play a game, browse the web or watch a movie on your PS3 while you wait on the FTP transfer to finish. Sitting there looking at the PS3 FTP homebrew app for 30 minutes or so while a game transfers isn't that much fun

It would be nice if we could take advantage of the background downloader system of the PS3 to allow us to make transfers while doing other tasks.

bigdaddie: You cant compile this under windows at all, go download backtrack 4 vmware image and I will attach what you need here to compile.

This is a quick tut I have also included in the zip along with all the files you will need.

ppu-sysroot: http://mirrors.kernel.org/ubuntu/pool/universe/p/ppu-sysroot/ppu-sysroot_2.0ubuntu3_i386.deb

ppu-sysroot64: http://mirrors.kernel.org/ubuntu/pool/universe/p/ppu-sysroot/ppu-sysroot64_2.0ubuntu3_i386.deb

ppu-binutils: http://lug.mtu.edu/ubuntu/pool/universe/c/cell-binutils/ppu-binutils_2.17cvs20070401-0ubuntu1_i386.deb

after you install those 3 install this one:

ppu-gcc: http://mirrors.kernel.org/ubuntu/pool/universe/c/cell-gcc/ppu-gcc_4.1.1r840-0ubuntu7_i386.deb

After those are all installed you have to install the rest by first copying sources.list to:

[Register or Login to view code]


After that u need to update:

After the update:

then open up .bashrc in your home folder and add:

I agree. Background ftp as a service is the way its been on xbox custom dashboards for years.

Not with this. Also why do you need such thing? What do you hope it'd bring you?

Kammy mean's you can compile a simple lvl2 program (patch) and load it into the lvl2 memory. It just makes the process alot simpler.
