Chen, Gang G
fc9ec5d88f hv: Derive decryption key from Seed for Trusty to decrypt attestation keybox
CSE FW uses an AEK (Attestation keybox Encryption Key) to encrypt the keybox
with AES-256-GCM algorithm before sending it to Android/Trusty. This key is
derived from the latest platform Seed by CSE FW with KDF (key derivation function)
HMAC-SHA256. After Trusty retrieves this encrypted keybox over HECI/MEI driver,
Trusty needs the same AEKkey to decrypt it. Hence, before Trusty launches,
Hypervisor derives the same AEK key from Platform Seed with the same algorithm
and the same derivation parameters, then sends this AEK along with Trusty vSeed
to Trusty world memory.

Since Platform Seed is only visible to Hypervisor and it must not be
sent to any guest VM, only Hypervisor can derive this AEK from this
Platform Seed, just like previous per-Trusty virtual Seed derivation.
Please note that Android Attestation Keybox is shared in a single hardware
platform, so all the Trusty instance/world can get the same AEK for
decryption even if there are multiple Android User OS/VMs running
on top of Hypervisor.

v1 --> v2:
	Add detailed description why we need the patch to derive an extra key

v2 --> v3:
	Convert API descriptions to Doxygen

 enter S3

                                            spinlock_release

Especially, considering the real spinlock release could be delayed
by cache.

Actually, the most content protected by up_count_spinlock is per

This patchset remove the up_count_spinlock and use atomic API

0255e62798 hv: resolve the negative impacts to UOS MSI/MSI-X remapping
After enabling vPCI in hypervisor for vm0, UOS may not able be launched
successfully. Consider this scenario (take MSI-X for example):

- DM makes hypercall to hypervisor to do MSI-X remapping on behalf of
  UOS guests.
- After the hypercall, VHM module in SOS kernel updates the physical
  MSI-X table with the physical Message Data/Addr.
- These MMIO write requests are intercepted by hypervisor, which will
  call ptdev_msix_remap() to do MSI-S remapping.

It may fail due to 2 possible reasons:

1) wrong target VM because:
  hypervisor thinks it's a VM0 MSI-X device but they have been registered
  as UOS guests through HC_SET_PTDEV_INTR_INFO hypercall.

2) wrong ptdev_msi_info->vmsi_data because:
  The virtual MSI-X table is supposed to hold virtual Message data/addr
  but the SOS VHM writes the physical ones to it.

This patch resolves these problems by ignoring the HC_VM_PCI_MSIX_REMAP
hypercall, so virtual and physical Message Data are the same from SOS'
perspective and it won't mess up the virtual PCI device in HV.

Also in HC_SET_PTDEV_INTR_INFO handler, vpci updates the target VM
when the PCI devices are assigned to different VMs.

The UOS' MSI/MSI-X remapping is triggered by hypervisor when SOS (either
DM or VHM) updates the Message Data/Addr.

8873859ade kconfig: optionally check if the ACPI info header is validated

a board-specific ACPI info header to be created by the user and placed under
bsp/include. Currently we'll fall back to the current platform-specific template
if such board-specific info is not available.

A configuration symbol ACPI_ENFORCE_VALIDATED_ACPI_INFO is also added to enforce
the existance of board-specific ACPI info header. Default configurations can set
this symbol if the template does not work on a board.

Updates to the getting started guide will be updated accordingly after the
offline tools to generate such header is available.

v2 -> v3:

* Rephrase the ACPI-info-related messages.

v1 -> v2:

* The generated header should depend on .config so that whenever any
  configuration changes, this header will be remade.

	Added new variables(ctx_rflags, ctx_rip, ctx_cs) in irq_desc
	On each interrupt this information is populated
	Added api's to access the irq_desc members

8ba333d275 HV: Added Initial support for SEP/SOCWATCH profiling
This patch adds support to sep/socwatch profiling
     Adds 2 new files include/arch/x86/profiling.h and arch/x86/profiling.c
     which contains most of the implementation for profiling,most of the functions
     in profiling.c have dummy implementation and will be implemented in next patches

     a. cpu.c, Initial profiling setup is done as part of bsp_boot_post
  and cpu_secondary_post flow
     b. vmcall.c, New ioctl is added for performing profiling related
  operations in vmcall_vmexit_handler
	ioctl - HC_PROFILING_OPS
        function - hcall_profiling_ops()
     c. common/hypercall.c, hcall_profiling_ops() implementation.
     d. hv_main.c, In vcpu_thread calling profiling related functions
  to save vm context
     e. acrn_hv_defs.h, list all the profiling command types

05834927cc HV: Fix boot failure of partition mode
When drdh_info_array[0].ignore = false with partition mode enabled,the following
assert error will be triggered when trying to boot vm:

Assertion failed in file arch/x86/vtd.c: fatal error

The root cause is that root_table_addr reading from CPU3(vm2's bsp) is NULL.

This patch move the init_iommu which initialize root_table_addr before starting
secondary cores and flush the cache at the end if the function to avoid getting
NULL pointer from secondary cores.

from prepare_vcpu to prepare_vm. And make sure it's called for
