Sunny,
Your bitmask idea works. But I think it might introduce unnecessary complexity. 
Keeping current implementation is good enough I think.

Thanks,
Ray

Laszlo,
        Would you like to make GetLoadOptionBuffer() public as well with my 
next patch?  I can help to do the passing change and add you into Signed-off-by 
as well. If you need it, let me know by end of today.  
Ruiyu,
        OK, got it. I will update the patch and send it out. 
        I just get an idea from your reply for enhancing the 
EfiBootManagerFindLoadOption, we may add a input parameter called IgnoreMember 
like the following for all the use cases so that all the consumers of this API 
don't need to create their own version. What do you think? If it works, I will 
send the other patch for this. 

typedef enum {
  IgnoreOptionType           = 0x01,        // BIT0
  IgnoreAttributes              = 0x02,        // BIT1
  IgnoreDescription           = 0x04,         // BIT2
  IgnoreFilePath                  = 0x08,         // BIT3
  IgnoreOptionalData        = 0x10,         // BIT4
  IgnoreOptionalDataSize = 0x20         // BIT5
} IGNORE_MEMBER_OF_ LOAD_OPTION;

EfiBootManagerFindLoadOption (
  IN CONST EFI_BOOT_MANAGER_LOAD_OPTION *Key,
  IN CONST EFI_BOOT_MANAGER_LOAD_OPTION *Array,
  IN UINTN                                                                      
  Count,
  IN IGNORE_MEMBER_OF_ LOAD_OPTION             IgnoreMember
  )

Regards,
Sunny Wang

Sunny,
Yes it's acceptable. Currently the implementation of *FindLoadOption does an 
exactly match. If other consumers of this API need to just match partially, 
they need to provide their own version instead of using this exposed one.

Laszlo,
Sorry I missed your comments. I am thinking about whether exposing the 
*GetLoadOptionBuffer() breaks the orthogonality because we already have 
EfiBootManagerProcessLoadOption() API. The latter one not only loads the buffer 
but also treats the buffer as a PECOFF buffer to start it.
The *GetLoadOptionBuffer() seems to do part of the job.
Anyway I think your request also makes sense. Just want to know if there is 
other better idea to not break the orthogonality.

Thanks,
Ray

On a similar note: in the message

http://thread.gmane.org/gmane.comp.bios.edk2.devel/759/focus=1153

point (10), I requested that the function BmGetLoadOptionBuffer() be made 
public.

Looks like there are now at least two Bm*() functions that see outside demand! 
:)

Thanks
Laszlo
