EfiCompress and TianoCompress are all originated from LZ77 algorithms and they have very little different, that different position set for Huffman code. EfiCompress is defined in EFI 1.1 spec and EfiRom tool need it to create a recognized compressed EFI driver. TianoCompress is for pursuer more size saving and it used be GenFfs and GenSection tools. So this patch: 1) Split EfiComress and TianoCompress in edkII’s tools 2) Change EfiRom tool use EfiCompress and GenFfs/GenSection use TianoCompress git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@2064 6f19259b-4bc3-4df7-8a09-765794883524

Routine Description:
|
|
|
|
The compression routine.
|
|
|
|
Arguments:
|
|
|
|
SrcBuffer - The buffer storing the source data
|
|
SrcSize - The size of source data
|
|
DstBuffer - The buffer to store the compressed data
|
|
DstSize - On input, the size of DstBuffer; On output,
|
|
the size of the actual compressed data.
|
|
|
|
Returns:
|
|
|
|
EFI_BUFFER_TOO_SMALL - The DstBuffer is too small. In this case,
|
|
DstSize contains the size needed.
|
|
EFI_SUCCESS - Compression is successful.
|
|
EFI_OUT_OF_RESOURCES - No resource to complete function.
|
|
EFI_INVALID_PARAMETER - Parameter supplied is wrong.
