2 | # Component description file for SMM Variable module. | |
3 | # | |
4 | # This module installs SMM variable protocol into SMM protocol database, | |
5 | # which can be used by SMM driver, and installs SMM variable protocol | |
6 | # into BS protocol database, which can be used to notify the SMM Runtime | |
7 | # Dxe driver that the SMM variable service is ready. | |
8 | # This module should be used with SMM Runtime DXE module together. The | |
9 | # SMM Runtime DXE module would install variable arch protocol and variable | |
10 | # write arch protocol based on SMM variable module. | |
11 | # | |
12 | # Caution: This module requires additional review when modified. | |
13 | # This driver will have external input - variable data and communicate buffer in SMM mode. | |
14 | # This external input must be validated carefully to avoid security issue like | |
15 | # buffer overflow, integer overflow. | |
