[PATCH 0/2] SortLib for UEFI SEC

[PATCH 0/2] SortLib for UEFI SEC

[Jeff Brasen]

This patch series enables support for BaseSortLib in UEFI SEC Phase.
This requires the addition of the AllocateZeroPool which is implemented
in the PrePiMemoryAllocationLib.

Jeff Brasen (2):
  EmbeddedPkg/PrePiMemoryAllocationLib: Added AllocateZeroPool()
  MdeModulePkg/BaseSortLib: Enable for all module types

[PATCH 1/2] EmbeddedPkg/PrePiMemoryAllocationLib: Added AllocateZeroPool()

[Jeff Brasen]

This function is exposed by the MemoryAllocationLib header.
An AllocateZeroPool() function has been added to fix modules depending on
this library and this function.

I guess this is just boilerplate, but what on earth is 'a valid buffer

[JB] Copied this from the MemoryAllocationLib but allocate with create creates a free-able buffer is created with a unique pointer but you can't read/write to it (as it has no .

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

[Ni, Ruiyu]

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];

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

[Jeff Brasen]

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

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

[Gao, Liming]

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>

Subject: Re: [edk2] [PATCH 2/2] MdeModulePkg/BaseSortLib: Enable for all module types


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,

Subject: RE: [edk2] [PATCH 2/2] MdeModulePkg/BaseSortLib: Enable for all module types

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

Yes. I will wait for another patch in this patch set to be reviewed.
