CHIPSEC
ac2ca7264f
UEFI shell. 2. Decompression of images in SPI flash parsing is only supported in Windows. 3. UEFI - Support for IA32 and i586 (Quark) 4. Added capability to use modules from an arbitrary path with the -I / --import command line option 5. Module functionality encapsulated in class inheriting BaseModule 6. Fixed loading platform specific configuration 7. Fixed issue with modules which run on multiple logical CPUs hanging on Bay Trail (Windows/Linux). The issue still exist when running from UEFI shell 8. Added template for a module - module_template.py 9. Added options to flush log files 10. Added ability to define custom platforms Driver changes: 1. Windows - Added IOCTL_ALLOC_PHYSMEM to allocate physical memory buffer 2. Linux - Fix wrpci defect

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! WARNING !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
|
|
Chipsec should only be used on test systems!
|
|
It should not be installed/deployed on production end-user systems.
|
|
|
|
There are multiple reasons for that:
|
|
|
|
1. Chipsec kernel drivers provide direct access to hardware resources to
|
|
user-mode applications (for example, access to physical memory). When installed on
|
|
production systems this could allow malware to access privileged hardware resources.
|
|
|
|
2. The driver is distributed as source code. In order to load it on Operating System
|
|
which requires kernel drivers to be signed (for example, 64 bit versions of
|
|
Microsoft Windows 7 and higher), it is necessary to enable TestSigning (or equivalent)
|
|
mode and sign the driver executable with test signature. Enabling TestSigning
|
|
(or equivalent) mode turns off an important OS kernel protection and should not be done
|
|
on production systems.
|
|
|
|
3. Due to the nature of access to hardware, if any chipsec module issues incorrect access
|
|
to hardware resources, Operating System can hang or panic.
