2015-07-01MdeModulePkg VariablePei: Merge from VariablePei in SecurityPkgStar Zeng
What to do: 1. Merge from VariablePei in SecurityPkg to VariablePei in MdeModulePkg. Why to do: 1. Remove code duplication and reduce maintenance effort. The code logic of VariablePei in SecurityPkg is same with VariablePei in MdeModulePkg.

2013-07-03MdeModulePkg: Variable drivers robustly handle crashes during Reclaim().Star Zeng
PEI variable implementation checks only the variable header signature for validity. This does not seem robust if system crash occurred during previous Reclaim() operation. If the crash occurred while FTW was rewriting the variable FV, the signature could be valid even though the rest of the FV isn't valid. Solution: Add a FaultTolerantWritePei driver to check and provide the FTW last write status, then PEI variable and early phase(before FTW protocol ready) of DXE variable can check the status and determine if all or partial variable data has been backed up in spare block, and then use the backed up data.

As the field recording this info is UINT16 width, the latter causes in IA32/X64 platform, it can only cache those variables from offset 0 to offset 2^16; in IPF platform, from offset 0 to offset 2^18(extend the scope by left-shift the offset two bits). when taking the former algorithm, the max range of caching variable is from offset 0 to offset 122*(2^16) git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@8625 6f19259b-4bc3-4df7-8a09-765794883524
2009-03-19Fix tracker 202216:linux runtime test issue.eric_tian
[Root Cause] The root cause is that in FindVariable function, original code logic will traverse all variable stored in variable volatile/non-volatile area. If the non-variable area is full and Linux sets a new variable, the caller of GetNextVariablePtr will get the address of next memory block, but this block doesn't be reserved as RUNTIME attribute. Therefore its corresponding page translation table doesn't exist and causes linux kernel panic. Note that, Variable Pei driver has not such issue as the flash area is accessed in pre-os environment.All page table entries are filled. The access to next memory block will not cause such issue. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@7910 6f19259b-4bc3-4df7-8a09-765794883524
