Re: [PATCH 2/2] MdeModulePkg/BaseSortLib: Enable for all module types

["Gao, Liming" <liming.gao@intel.com>]

Jeff:
  Thanks for your case. PrePiMemoryAllocationLib is a MemoryAllocationLib implementation that doesn't depend on PEI or DXE service. So, MemoryAllocationLib may be used in BASE type. And, I find MdeModulePkg\Library\BaseBmpSupportLib\BaseBmpSupportLib.inf is BASE type and consumes MemoryAllocationLib. So, I think your change is OK. Reviewed-by: Liming Gao <liming.gao@intel.com>

Thanks

For defining it as a BASE type i changed that to that as there is a MemoryAllocationLib defined for the various phases. For example, SEC uses EmbeddedPkg/Library/PrePiMemoryAllocationLib (other patch in this series implements the AllocateZeroPool that is needed for this).



I am not opposed to an allocation-less SortLib but was trying to enable this capability without impact to other users of this library.



Thanks,

Jeff

SortLib depends on MemoryAllocationLib.
How can it be a BASE type library?

Can we do it in two options?
1. Change the SortLib API to accept a temporary buffer from caller. So the MemoryAllocationlIb dependency can be removed.
2. Do not change SortLibAPI but uses a fixed-size temporary buffer internally. E.g.: UINT8 Buffer[MAX_ELEMENT_SIZE];


Thanks/Ray
