			This is quite ugly, it only sets up the function pointers the first time that fluch_cache_page() is called, and _no other functions_. It was all I needed however.

With the fix of fuse above, DVDfs is confirmed to work correctly. However, there is not a lot of CPU to play with, and decrypting CSS in CPU is "just enough". You will probably find there are scenes with slow down however.

			You will need to put '''dvdfs''' and '''fusermount''' in a directory, and change '''PATH''' to include it.

+Based on my [[NMT:cross|cross-compile]] tool chain. However, note that Linux kernel can not easily be built on platforms other than Linux. It uses HOST_CC to build some items that assume you have Linux headers.

== Fuse ==

I downloaded the latest '''fuse''' I could find, which at the time was '''fuse-2.7.2'''.

Compiling turned out to be a real hassle, the compiled kernel version string has to match that of my compiled kernel module version string.

The string we need to get is

2.6.15-sigma preempt MIPS32_R2 32BIT gcc-4.0

So, change Makefile to have '''EXTRAVERSION = -sigma''', then turn on '''preemptive''' kernel, and '''MIPS R2''' under CPU Architecture. I compile the kernel with:

make V=1 CROSS_COMPILE=mipsel-linux-uclibc- ARCH=mips modules

Based on my toolchain.
