ldvd-1.2.tar.gz tarball with fuse, dvdfs and fusermount ldvd-1.1.tar.gz tarball with fuse, dvdfs and fusermount ldvd-1.0.tar.gz tarball with fuse, dvdfs and fusermount
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 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.
After that, I configured fuse with:
./configure --host=mipsel-linux-uclibc --enable-kernel-module --with-kernel=/home/lundman/cross/linux-220.127.116.11/ --enable-static cd kernel make V=1 CROSS_COMPILE=mipsel-linux-uclibc- ARCH=mips
Which gives me a fuse.ko. This does not yet load, due to:
insmod -v fuse.ko Using fuse.ko fuse: Unknown symbol capable fuse: Unknown symbol _spin_unlock fuse: Unknown symbol add_preempt_count fuse: Unknown symbol __might_sleep fuse: Unknown symbol _spin_lock fuse: Unknown symbol sub_preempt_count insmod: cannot insert 'fuse.ko': Success (2): Success
Ahh, ok instead of picking malta board, I picked atlas and voila:
# insmod fuse3.ko <4>fuse init (API version 7.8) <4>fuse distribution version: 2.7.2
Due to a bug in 2.6.15, with cache coherency, fuse never ran properly. There was a work around by calling flush_cache_page but this function is missing in the running kernel. I have managed to pull it out of a similar MIPS CPU tree, and put them together with a hammer.
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.
