CHIPSEC
0654edca19
Revision 1.2.0 -------------- This version includes the following new or updated modules: #. Merged common.secureboot.keys module into common.secureboot.variables module #. Updated tools.secureboot.te module to be able to test PE/TE issue on Linux or UEFI shell #. Updated tools.smm.smm_ptr module This version includes the following updates: #. Added the *controls* abstraction. Modules are encouraged to use ``get_control`` and ``set_control`` when interacting with platform registers. This permits greater flexibility in case the register that controls a given feature or configuration changes between platform generations. The controls are defined in the platform XML file. At this time, only a small number of controls are defined. We plan to move existing modules over to this new mechanism. #. Added XML Schema for the XML configuration files #. Support for reading, writing, and listing UEFI variables from the UEFI Shell environment has been added. #. Added support for decompression while SPI flash parsing via ``decode`` or ``uefi decode`` commands in Linux #. Added basic ACPI table parsing to HAL (RSDP, RSDT/XSDT, APIC, DMAR) #. Added UEFI tables searching and parsing to HAL (EFI system table, runtime services table, boot services table, DXE services table, EFI configuration table) #. Added DIMM Serial Presence Detect (SPD) ROM dumping and parsing to HAL #. Added ``uefi s3bootscript`` command parsing the S3 boot script to chipsec_util.py #. Added virtual-to-physical address translation function to Linux/EFI/Windows helpers #. Added support of server platforms (Haswell server and Ivy Town) to chipset.py This version has the following known issues: #. Decompression of images in SPI flash parsing is not available in UEFI shell. #. When calling alloc_phys_mem, the argument to set maximum physical address (max_pa) for allocation is ignored on linux. A message will be printed in dmesg if the allocation is above the max_pa that is passed in, but the call will return anyway. #. UEFI Shell environment does not support ``cpuid`` or ``get_thread_count``. There are functions that simply warn that they are not supported. #. Size of PCIEXBAR (MMCFG) is calculated incorrectly
