2009-06-03fix the issue of Inadequate Memory Allocation in Variable Serviceseric_tian
In UpdateVariableInfo(), the code incorrectly allocate a small memory, whose size equate with the number of Unicode name.

2009-04-071. The original code has a bug on calculate the size of SCRATCH_SIZE. It ↵eric_tian
should be maximum value between PcdMaxVariableSize and PcdMaxHardwareErrorVariableSize. 2. Boot time variable reclaim issue is caused by incorrect flash layout. Platform integrator should ensure that the size of variable region must less than FTW spare space size. 3. Per UEFI Specification, variables of attribute HARDWARE_ERROR_RECORD are guaranteed to have its own storage space size.original implementation doesn’t meet this requirement git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@8029 6f19259b-4bc3-4df7-8a09-765794883524

2009-03-16Fix 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. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@7890 6f19259b-4bc3-4df7-8a09-765794883524

2009-03-091. retire the FvbServiceLib. Directly locating FVB protocol to access ↵eric_tian
interfaces. 2. modify the method of getting right FVB protocol interface. move the notification event of FVB installation into variable driver. and also move ExitBootService event into variable driver. 3. use EFI_FVB2_WRITE_STATUS flag to distinct whether the FVB protocol supports writing operation or not.Currently, DxeCore installs FVB which has ~EFI_FVB2_WRITE_STATUS(that is, disable write) attrbiute. FvbRuntimeDxe driver should provide a full FVB protocol, which returns EFI_FVB2_WRITE_STATUS attribute to signify itself provide writable FVB protocol. So other modules which need write data by FVB protocol can locate it correctly. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@7835 6f19259b-4bc3-4df7-8a09-765794883524

2008-03-19[Description]:yshang1
The patch enhanced variable services to support: 1) If adding variable does not execute completely, the state is in_deleted, the next time find variable should have to retrieve the in_deleted variable. 2) when Reclaiming the variable storage, the 1) variable should be considered. [Impaction]: This is backward-compatible update. [Reference Info]: 9552, 8632 git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@4916 6f19259b-4bc3-4df7-8a09-765794883524

2008-01-141) Replace MACRO with C functions.yshang1
2) Add HEADER_VALID_ONLY state of variable, which represents only the header is valid and the data/name is stale. This may be caused by incomplete data updating. Adding the state helps to check whether the header is valid. If variable header is valid, then we must skip the data of variable with the valid size. If the header is invalid, we should only skip the header of variable. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@4555 6f19259b-4bc3-4df7-8a09-765794883524

2008-01-10Align the header of variable from 1 to 4, which can avoid the size of ↵yshang1

2008-01-091) Fix the bug that Variable Cache Search does not be protected by lock ↵yshang1
during boot time. It potentially results in the info from GetVariable() is not correct. 2) Check the integrity of Variable header. In original implementation, if not whole header is correct, then the variable will be treat as invalid. typically, if the NameSize has been programed but the DataSize not, then the variable storage would failed to set new variable. 3) Change the Variable Header Alignment from 1 to 4 bytes on x86. It avoids the DataSize or NameSize cross two blocks. For example, in original implementation, if the NameSize crosses two block, when the FLASH manipulation is interrupted after programed HSB of NameSize and prior to program LSB of NameSize on next block, then the invalid variable header will result in the Variable Storgae broken. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@4538 6f19259b-4bc3-4df7-8a09-765794883524
