[edk2-devel] [PATCH v7] IntelFsp2WrapperPkg : FSPM/S UPD data address based on Build Type
Posted by Ashraf Ali S 2 years, 7 months ago 
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3642
when the module is not building in IA32 mode which will lead to
building error. when a module built-in X64 function pointer will be the
size of 64bit width which cannot be fit in 32bit address which will lead
to error. to overcome this issue introducing the 2 new PCD's
for the 64bit modules can consume it.
Creating the API's to support different architecture

Re: [edk2-devel] [PATCH v7] IntelFsp2WrapperPkg : FSPM/S UPD data address based on Build Type
Posted by Zeng, Star 2 years, 7 months ago 
Curious: It does not work to have one function implementation like below?

UINTN
EFIAPI
GetFspmUpdDataAddress (
  VOID
  )
{
  if (PcdGet64 (PcdFspmUpdDataAddress) != 0) {
    return (UINTN) PcdGet64 (PcdFspmUpdDataAddress64);
  } else {
    return (UINTN) PcdGet32 (PcdFspmUpdDataAddress);
  }
}

Thanks,
Star

Re: [edk2-devel] [PATCH v7] IntelFsp2WrapperPkg : FSPM/S UPD data address based on Build Type
Posted by Ashraf Ali S 2 years, 7 months ago 
Hi., @Zeng, Star

Creating a single function is doable, but the problem with that is 
If someone set the PCD  PcdFspmUpdDataAddress64 accidentally which should be applicable only in X64. Since the PCD has some junk value, it will return the false data in IA32 case. Which will break everything with respect to FSP-S/M.

To Avoid Such cases separating the IA32 vs X64 is more feasible. And easily differentiating with IA32 and X64.

Ashraf Ali S

Subject: RE: [PATCH v7] IntelFsp2WrapperPkg : FSPM/S UPD data address based on Build Type

Curious: It does not work to have one function implementation like below?

UINTN
EFIAPI
GetFspmUpdDataAddress (
  VOID
  )
{
  if (PcdGet64 (PcdFspmUpdDataAddress) != 0) {
    return (UINTN) PcdGet64 (PcdFspmUpdDataAddress64);
  } else {
    return (UINTN) PcdGet32 (PcdFspmUpdDataAddress);
  }
}

Thanks,
Star

Re: [edk2-devel] [PATCH v7] IntelFsp2WrapperPkg : FSPM/S UPD data address based on Build Type
Posted by Zeng, Star 2 years, 7 months ago 
If someone sets the PCD PcdFspmUpdDataAddress64 accidentally, it is better to be caught by some way but ignored.

BTW, if the function GetFspmUpdDataAddress() is a internal function in the module, no EFIAPI is needed in the declaration.

And, @Chiu, Chasel, is PcdFspmUpdDataAddress supposed to be always configured to be Dynamic type by platform?

If yes, maybe we can have two help functions in FspWrapperPlatformLib like below and remove "PcdsFixedAtBuild, PcdsPatchableInModule" in dec. Platform can use SetFspmUpdDataAddress() without need to be aware of the PCDs.

UINTN
EFIAPI
GetFspmUpdDataAddress (
  VOID
  )
{
  if (PcdGet64 (PcdFspmUpdDataAddress64) != 0) {
    return (UINTN) PcdGet64 (PcdFspmUpdDataAddress64);
  } else {
    return (UINTN) PcdGet32 (PcdFspmUpdDataAddress);
  }
}

VOID
EFIAPI
SetFspmUpdDataAddress (
  IN UINTN Address
  )
{
  if (Address <= MAX_UINT32) {
    PcdSet32S (PcdFspmUpdDataAddress, (UINT32) Address);
  } else {
    PcdSet64S (PcdFspmUpdDataAddress64, (UINT64) Address);
  }
}

Hi., @Zeng, Star

Creating a single function is doable, but the problem with that is If someone set the PCD  PcdFspmUpdDataAddress64 accidentally which should be applicable only in X64. Since the PCD has some junk value, it will return the false data in IA32 case. Which will break everything with respect to FSP-S/M.

To Avoid Such cases separating the IA32 vs X64 is more feasible. And easily differentiating with IA32 and X64.

Curious: It does not work to have one function implementation like below?

UINTN
EFIAPI
GetFspmUpdDataAddress (
  VOID
  )
{
  if (PcdGet64 (PcdFspmUpdDataAddress64) != 0) {
    return (UINTN) PcdGet64 (PcdFspmUpdDataAddress64);
  } else {
    return (UINTN) PcdGet32 (PcdFspmUpdDataAddress);
  }
}

Thanks,
Star
