* spuldrfs is like spuisofs but can also execute loaders like lv1ldr or isoldr.
* I used this driver e.g. to run modified lv1ldr to dump my ENCDEC keys.
* GIT repo: http://gitorious.ps3dev.net/ps3linux/spuldrfs
=Features=
* MFC data segment faults are handled by the driver. That means you do not have to worry about it.
* Large data buffers which can be used for data exchange between SPU and PPU.
* Data buffers are not physically continuous which eliminates the RAM allocation problem.
* Full access to all SPU registers from user-space.

=Loading Firmware From Linux Kernel Module=
* It's a really neat trick :)

* We could use it to load metldr automatically into kernel space.
