[PATCH v2 0/5] Add Cloud Hypervisor support for x86

[PATCH v2 0/5] Add Cloud Hypervisor support for x86

[sebastien.boeuf]

From: Sebastien Boeuf <sebastien.boeuf@intel.com>

This series aims at adding the support for the Cloud Hypervisor platform
to the OVMF firmware for x86 architecture.

The goal is to allow the same binary to be used either by QEMU or Cloud
Hypervisor, using the Cloud Hypervisor way as a fallback if the fw_cfg
mechanism is not present.

Sebastien Boeuf (5):
  OvmfPkg: Handle Cloud Hypervisor host bridge
  OvmfPkg: Create global entry point for SMBIOS parsing
  OvmfPkg: Retrieve SMBIOS from Cloud Hypervisor
  OvmfPkg: Generalize AcpiPlatformDxe
  OvmfPkg: Install ACPI tables for Cloud Hypervisor

[PATCH v2 2/5] OvmfPkg: Create global entry point for SMBIOS parsing

[sebastien.boeuf]

From: Sebastien Boeuf <sebastien.boeuf@intel.com>

Move the generic entry point part out of Qemu.c to anticipate the
addition of new ways of retrieving the SMBIOS table.

[PATCH v2 3/5] OvmfPkg: Retrieve SMBIOS from Cloud Hypervisor

[sebastien.boeuf]

From: Sebastien Boeuf <sebastien.boeuf@intel.com>

Add a fallback on the SMBIOS code to find the SMBIOS table for Cloud
Hypervisor if it couldn't be found for Qemu through fw_cfg.

[PATCH v2 4/5] OvmfPkg: Generalize AcpiPlatformDxe

[sebastien.boeuf]

From: Sebastien Boeuf <sebastien.boeuf@intel.com>

Don't make the package Qemu centric so that we can introduce some
alternative support for other VMMs not using the fw_cfg mechanism.

This patch is purely about renaming existing files with no functional
change.

Re: [PATCH v2 1/5] OvmfPkg: Handle Cloud Hypervisor host bridge

[Yao, Jiewen]

Is below code right?

+  case CLOUDHV_DEVICE_ID:
     mRegisterValues = mRegisterValuesQ35;

+    case CLOUDHV_DEVICE_ID:
        mLegacyInterruptDevice = LEGACY_INT_DEV_Q35;

I am not sure if it is the best pattern to describe which register is reused from Q35, and which one is CV specific.

Maybe just redefine all set of registers, even the value is same ?


Thank you
Yao Jiewen

Hmm?  mAcpiPmBaseAddress + mAcpiHwReducedSleepCtl should be treated
equal here (zero both or zero none).

I think explicitly zeroing is not needed, the variables should be in a
zero-initialized memory block.

if (mAcpiHwReducedSleepCtl)
