eric_tian 2fcdca1d73 1. The original code has a bug on calculate the size of SCRATCH_SIZE. It 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

jljusten bd682470fc Prefix variable services functions with 'Emu'. Specifically this is 
done to avoid a conflict with the 'GetVariable' function defined
in edk2/MdePkg/Include/Library/UefiLib.h.

eric_tian fba0ee1f4c Fix tracker 202216:linux runtime test issue. 
[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.

eric_tian 00f3851372 retire FvbServiceLib class in MdeModulePkg, and also remove the two instances in MdeModulePkg and ItaniumPlatformPkg.

eric_tian 8a9e0b7274 1. retire the FvbServiceLib. Directly locating FVB protocol to access 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.

 2009-03-09 06:39:13 +00:00
eric_tian 5bb820af59 1. add missing free operation in conditional branch. 
2. when variable store header is invalid status, we will return EFI_VOLUME_CORRUPTED to let code assert, which is helpful to find root cause quickly.

eric_tian 3709c4cd5b 1. delete Include/Guid/VariableInfo.h 
2. move VariableFormat.h into GUID directory and change the “Signature” field of the VARIABLE_STORE_HEADER to gEfiVariableGuid value.
3. merging VARIABLE_INFO_ENTRY structure into the new Include/Guid/VariableFormat.h
4. change gEfiVariableInfoGuid into gEfiVariableGuid.
5. modify FDF files to use new guid value instead of the original signature.
6. all code related to signature is changed to use guid value.
