TODO: Test UEFI functionality
Fully test on 64 and 32-bit platforms
========================
| Chipsec linux driver |
========================
This module is built on/adapted from fmem 1.5.0 and LOLA (Low Level Access)
NOTE:
You may need run apt-get install python-dev for the Python.h header (needed for switching cpu affinity).
If you already have this in a non-standard location (i.e. any other than /usr/include/python-2.7), you can manually edit the path in source/driver/linux/Makefile
To build:
make
To load kernel module:
make install
- or -
./run.sh
To remove kernel module:
make uninstall
- or -
rmmod chipsec
TESTED ON:
Linux 3.2.6 x32 (Mint/Ubuntu)
Linux 2.6.32 x32 (Ubuntu)
Fedora 20 LXDE 64bit
-------------
fmem 1.5.0
This module creates /dev/fmem device,
that can be used for dumping physical memory,
without limits of /dev/mem (1MB/1GB, depending on distribution)
Tested on i386 and x64, feel free to test it on
different architectures. (and send report please)
Cloned from linux/drivers/char/mem.c
(so GPL license apply)
Original name of this tool was fdump,
which was conflict with already existing tool,
so name was changed to fmem
Bug reports and patches welcome.

Usage:
$ make
# ./run.sh
# dd if=/dev/fmem of=... bs=1MB count=...
-----
BUGS: if you do something like # dd if=/dev/fmem of=dump
dd will never stop, even if there is no more physical RAM
on the system. This is more a feature, because Linux kernel
don't have stable API, and detection of mapped areas can be
tricky on older kernels. Because primary usage for fmem is
memory forensic, I think it is safer to specify
amount of RAM by hand.
