Lzfse-Char-Dev

Kerenel module for character device, used to test in-kernel lzfse library.

Building

Project Makefile expects kernel source tree to be in directory ../linux. Also, patch that adds lzfse support should be applied. To build module, run:

$ make

Preparation

Then, module can be inserted as usual

# insmod lzfse_cdev.ko

Next, create two character devices, for example lzfse_encode and lzfse_decode. Major number is 566, minor number for encoder is 0, for decoder is 1:

# mknod lzfse_encode c 566 0
# mknod lzfse_decode c 566 1

Usage

To compress data

$ cat file > lzfse_encode
$ cat lzfse_encode > file.lzfse

To decompress

$ cat file.lzfse > lzfse_decode
$ cat lzfse_decode > file

Be careful - data buffers have limited size and are shared between all created devices
