[v13] Adds AmdSmmCpuFeaturesLib and MmSaveStateLib

[edk2-devel] [PATCH v13 0/8] Adds AmdSmmCpuFeaturesLib and MmSaveStateLib

Posted by Abdul Lateef Attar via groups.io 7 months ago

Backward-compatibility changes:
  This patch series removes the SmmCpuFeaturesReadSaveStateRegister
  and SmmCpuFeaturesWriteSaveStateRegister interface/function.
  SmmReadSaveState() and SmmWriteSaveState() now directly invokes MmSaveStateLib
  routines to save/restore registers.

PR: https://github.com/tianocore/edk2/pull/4392

Hi @Ray Ni,
We are almost there... We need your help to review this patch set as we need this library to be part of 202305 stable release.

Re: [edk2-devel] [PATCH v13 0/8] Adds AmdSmmCpuFeaturesLib and MmSaveStateLib

Posted by Ni, Ray 6 months, 3 weeks ago

Abner,
Sure. I will review the new patch set.

But I am afraid this patch set cannot be included in 202305 stable release because the edk2 repo
has been locked for quite a while for 202305 release and is about to unlocked.

Thanks,
Ray

Re: [edk2-devel] [PATCH v13 0/8] Adds AmdSmmCpuFeaturesLib and MmSaveStateLib

Posted by Chang, Abner via groups.io 6 months, 3 weeks ago

[AMD Official Use Only - General]

Let's talk to Liming to see if we have chance to make this included in 202305 as the review process of this patch set looks to me close to finish.

Thanks
Abner

Re: [edk2-devel] [PATCH v13 0/8] Adds AmdSmmCpuFeaturesLib and MmSaveStateLib

Posted by Ni, Ray 6 months, 1 week ago

I spent some time to verify if the IntelMmSaveStateLib behaves the same as the default implementation in CpuSmm driver.
The result looks good with following embedded test code in BSPHandler():

    for (Cpu = 0; Cpu < mMaxNumberOfCpus; Cpu++) {
      DEBUG ((DEBUG_INFO, "Testing SMRAM Read CPU[%d]...", Cpu));
      for (Register = EFI_MM_SAVE_STATE_REGISTER_GDTBASE; Register <= EFI_MM_SAVE_STATE_REGISTER_PROCESSOR_ID; Register++) {
        DEBUG ((DEBUG_INFO, " Register(%d)...\n", Register));
        switch (Register) {
          case EFI_MM_SAVE_STATE_REGISTER_IO:
            Width = sizeof (IoInfo);
            break;
          case EFI_MM_SAVE_STATE_REGISTER_LMA:
            Width = 1;
            break;
          default:
            Width = 8;
            break;
        }

        Status  = MmSaveStateReadRegister (Cpu, Register, Width, &IoInfo);
        Status2 = ReadSaveStateRegister (Cpu, Register, Width, &IoInfo2);
        ASSERT (Status == Status2);
        if (!EFI_ERROR (Status)) {
          ASSERT (CompareMem (&IoInfo, &IoInfo2, Width) == 0);
        } else {
          if (Status == EFI_INVALID_PARAMETER) {
            Status  = MmSaveStateReadRegister (Cpu, Register, sizeof (UINT32), &IoInfo);
            Status2 = ReadSaveStateRegister (Cpu, Register, sizeof (UINT32), &IoInfo2);
            ASSERT (Status == Status2);
            ASSERT (Status == EFI_SUCCESS);
            ASSERT (CompareMem (&IoInfo, &IoInfo2, sizeof (UINT32)) == 0);
          }
        }
      }
    }

But, one comment: EFI_SMM_SAVE_STATE_REGISTER_PROCESSOR_ID is not handled by MmSaveStateLib. It's handled by
CpuSmm driver.
I am ok with that. Can you please update the MmSaveStateLib header file to explicitly mention that? I am afraid I may forget
this without clear function header comments.

Others look good to me.

Thanks,
Ray
