[PATCH v2 1/6] ArmPkg/ProcessorSubClassDxe: Get processor version from OemMiscLib

[Nhi Pham]

From: Minh Nguyen <minhn@amperecomputing.com>

In some scenarios, the processor version may be updated dynamically
from pre-UEFI firmware during booting. But the processor version is
fixed with PCD (PcdProcessorVersion), so it can not be updated it
dynamically. This patch will support setting that value both
statically and dynamically.

[PATCH v2 2/6] ArmPkg: Correct return value of "SMCCC_ARCH_SOC_ID" Function ID call

[Nhi Pham]

From: Minh Nguyen <minhn@amperecomputing.com>

According to "SMC Calling Convention" specification, section 7.4,
return value of Arm Architecture Calls is stored at first argument of
SMC aguments (ARM_SMC_ARGS). This value can be negative values indicating
error or positive values (including zero) indicating success. Positive
value would contain information of respective Function ID (Section 7.3.4
and 7.4.4).

For that reason, "SMCCC_VERSION" and "SMCCC_ARCH_FEATURES"
Function ID calls read return value from "SmcCallStatus" variable
(Args.Arg0 - first argument of SMC call). But "SMCCC_ARCH_SOC_ID"
Function ID call is reading return value from "SmcParam" variable
(Args.Arg1 - second argument of SMC call) so it leads to unexpected
results of "Jep106Code" and "SocRevision". This patch is to correct it.

Hi Nhi,

This patch series is fine for me. But we need permission from Ard or Leif for proceeding further.

Re: [PATCH v2 0/6] ArmPkg/SMBIOS fixes and improvements

[Sami Mujawar]

Hi Nhi,

I was building this patch series and realised that merging this patch series will break the SbsaQemu platform builds.
Would you be submitting a patch to update SbsaQemu platform to match this series, please?

Also, can you check if this patch breaks any other platform.

Regards,

Sami Mujawar
