e63d32ac02 hv: delay enabling SMEP/SMAP until the end of PCPU initialization
Host ACPI parsing is needed during initialization only, not in run time.
Hence we don't need to clear U flag for memory in reserved or ACPI type
E820 entries.

- move enable_smep() and enable_smap() to the end of init_pcpu_post(),
  so stac()/clac() can be removed from any init code before this point.

- call init_seed() before init_pcpu_post(), and rmeove stac()/clac() from
  init_seed().

c71cf753eb ACRN/HV: Add one new board configuration for ACRN-hypervisor
The memory size and IOMMU number are refined to meet with ICL board requirement.
Otherwise the ACRN hypervisor can't be booted on the new ICL board.
ICL(the abbreviation of Ice Lake) is the next generation platform based on 10nm.
CPU is based on Sunny Cove microarchitecture and GPU is based on gen11.
The new board is named as icl-rvp.

04d82e5c0f HV: return virtual lapic id in vcpuid 0b leaf
Currently vlapic id of SOS VM is virtualized, it is indexed by vcpuid in
physical APIC id sequence, but CPUID 0BH leaf still report physical
APIC ID. In SDC/INDUSTRY scenario they are identical mapping so no issue
occured. In hybrid mode this would be a problem because vAPIC ID might
be different with pAPIC ID. We need to make the APIC ID which returned from
CPUID consistent with the one returned from LAPIC register.

ea7ca8595c HV: use tag to specify multiboot module
Previously multiboot mods[0] is designed for kernel module for all
pre-launched VMs including SOS VM, and mods[0].mm_string is used
to store kernel cmdline. This design could not satisfy the requirement
of hybrid mode scenarios that each VM might use their own kernel image
also ramdisk image. To resolve this problem, we will use a tag in
mods mm_string field to specify the module type. If the tag could
be matched with os_config of VM configurations, the corresponding

cee2f8b288 ACRN/HV: Refine the function of init_vboot to initialize the depriv_boot env correctly
Currently when get_rsdp is called, the EFI depriv_boot env is not initialized.
In such case it will fallback to the legacy mechanism of ACPI table.
If the ACPI table based on legacy mechanism is not found, it will fail to get
the ACPI table and then the system will hang.
On the old platform it still can parse the ACPI table from legacy mechanism.
In fact when EFI RSDP exists, the EFI RSDP is preferred instead of legacy ACPI
RSDP.

In order to avoid multiple calling of depriv_init_boot, the init_boot_operations
is renamed and called after X2apic is enabled(early_init_lapic).

bfc08c2812 hv: move msr_bitmap from acrn_vm to acrn_vcpu_arch
At the time the guest is switching to X2APIC mode, different VCPUs in the
same VM could expect the setting of the per VM msr_bitmap differently,
which could cause problems.

Considering different approaches to address this issue:
1) only guest BSP can update msr_bitmap when switching to X2APIC.
2) carefully re-write the update_msr_bitmap_x2apic_xxx() functions to
   make sure any bit in the bitmap won't be toggled by the VCPUs.
3) make msr_bitmap as per VCPU.

We chose option 3) because it's simple and clean, though it takes more
memory than other options.

BTW, need to remove const modifier from update_msr_bitmap_x2apic_xxx()
functions to get it compiled.

536c69b9ff hv: distinguish between LAPIC_PASSTHROUGH configured vs enabled
ACRN supports LAPIC emulation for guests using x86 APICv. When guest OS/BIOS
switches from xAPIC to x2APIC mode of operation, ACRN also supports switching
froom LAPIC emulation to LAPIC passthrough to guest. User/developer needs to
configure GUEST_FLAG_LAPIC_PASSTHROUGH for guest_flags in the corresponding
VM's config for ACRN to enable LAPIC passthrough.

This patch does the following

1)Fixes a bug in the abovementioned feature. For a guest that is
configured with GUEST_FLAG_LAPIC_PASSTHROUGH, during the time period guest is
using xAPIC mode of LAPIC,  virtual interrupts are not delivered. This can be
manifested as guest hang when it does not receive virtual timer interrupts.

2)ACRN exposes physical topology via CPUID leaf 0xb to LAPIC PT VMs. This patch
removes that condition and exposes virtual topology via CPUID leaf 0xb.

using DIRECT_BOOT_MODE and all other VMS, they will use general_sw_loader as
vm_sw_loader and go through init_general_vm_boot_info() for virtual boot vm
info filling.

this patch also move spurious handler initilization for de-privilege mode from
boot/guest/deprivilege_boot.c to boot/guest/vboot_info.c, and just set it in
deprivilege sw_loader before irq enabling.

865ee2956e hv: emulate ACPI reset register for Service OS guest
Handle the PIO reset register that is defined in host ACPI:

Parse host FADT table to get the host reset register info, and emulate
it for Service OS:

- return all '1' for guest reads because the read behavior is not defined
  in ACPI.
- ignore guest writes with the reset value to stop it from resetting host;
  if guest writes other values, passthru it to hardware in case the reset
  register supports other functionalities.

86f5993bc9 hv: vlapic: fix tpr virtualization when VID is not enabled.
1) According SDM Vol 3, Chap 29.1.2, Any VM exit caused by TPR virtualization
is trap-like: the instruction causing TPR virtualization completes before the VM
exit occurs (for example, the value of CS:RIP saved in the guest-state area of
the VMCS references the next instruction). So we need to retain the RIP.
2) The previous implement only consides the situation the guest will reduce the
TPR. However, the guest will increase it. So we need to update the PPR before we
find a deliverable interrupt. For examples: a) if the guest increase the TPR before
a irq windows vmexit, we need to update the PPR when check whether there has a pending
delivery interrupt or not; b) if the guest increase the TPR, then an external irq raised,
we need to update the PPR when check whether there has a deliverable interrupt to inject
to guest.

20f97f7559 restruct boot and bsp dir for firmware stuff
currently, ACRN hypervisor can either boot from sbl/abl or uefi, that's
why we have different firmware method under bsp & boot dirs.
but the fact is that we actually have two different operations based on
different guest boot mode:
1. de-privilege-boot: ACRN hypervisor will boot VM0 in the same context as
native(before entering hypervisor) - it means hypervisor will co-work with
ACRN UEFI bootloader, restore the context env and de-privilege this env
to VM0 guest.
2. direct-boot: ACRN hypervisor will directly boot different pre-launched
VM(including SOS), it will setup guest env by pre-defined configuration,
and prepare guest kernel image, ramdisk which fetch from multiboot modules.

this patch is trying to:
- rename files related with firmware, change them to guest vboot related
- restruct all guest boot stuff in boot & bsp dirs into a new boot/guest dir
- use de-privilege & direct boot to distinguish two different boot operations

this patch is pure file movement, the rename of functions based on old assumption will
be in the following patch.

IRTE is freed if ptirq entry is released from remove_msix_remapping() or
remove_intx_remapping(). But if it's called from ptdev_release_all_entries(),

This patch adds a release_cb() callback function to do any architectural
specific cleanup. In x86, it's used to release IRTE.

On VM shutdown, vpci_cleanup() needs to remove MSI/MSI-X remapping on
ptirq entries, thus it should be called before ptdev_release_all_entries().

3bb4308361 HV: check vm id param when dispatching hypercall
If the vmcall param passed from guest is representing a vmid, we should
make sure it is a valid one because it is a pre-condition of following
get_vm_from_vmid(). And then we don't need to do NULL VM pointer check
in is_valid_vm() because get_vm_from_vmid() would never return NULL.

1b7d33a426 hv: separate host e820 and SOS ve820
There are 2 reasons why SOS ve820 has to be separated from host e820:
- in hybrid mode, SOS may not own all the host memory.
- when SOS is being re-launched, it needs an untainted version of host
  e820 to create SOS ve820.

This patch creates sos_e820 table for SOS and keeps host e820 intact
during SOS creation.

578592b566 vlapic: refine IPI broadcast to support x2APIC mode
According to SDM 10.6.1, if dest fields is 0xffU for register
ICR operation, that means the IPI is for broadcast.

According to SDM 10.12.9, 0xffffffffU of dest fields for x2APIC
means IPI is for broadcast.

We add new parameter to vlapic_calc_dest() to show whether the
dest is for broadcast. For IPI, we will set it according to
dest fields. For ioapic and MSI, we hardcode it to false because
no broadcast for ioapic and MSI.

6915264740 hv: Use virtual APIC IDs for Pre-launched VMs
For Pre-launched VMs, ACRN uses mptable for reporting APIC IDs to guest OS.
In current code, ACRN uses physical LAPIC IDs for vLAPIC IDs.
This patch is to let ACRN use vCPU id for vLAPIC IDs  and also report the same
when building mptable. ACRN should still use physical LAPIC IDs for SOS
because host ACPI tables are passthru to SOS.

83d11bbff8 HV: Register S5 pio handler for dm-launched RTVM
The virtual pm port of RTVM is intercepted by HV. But the HV needs to inform the DM as well.
So we will forward the virtual S5 request to DM too

The handler in HV just set the pm state flag (VM_POWERING_OFF) which indicate that the RTVM is powering
off by itself. Meanwhile, there are data resources in VHM and DM should be released once we handle the PM
of RTVM in HV. So, return to DM to go through the entire VM destroy cycles to release the resources.
During the cycles, the DM will try to pause vm through hypercall. In the hypercall handler in HV, we will
check the pm state flag. If it is set, pause all the vCPUs of the vm. Otherwise, reject the request.

In this way, we can make sure that RTVM can only trigger its s5 by itself. All
other S5 request from external will be rejected.

Here is sequence chart of RTVM s5.

9abd469da2 config: unify board names to lowercase
Currently board names are used inconsistently across the project.

* Name of defconfigs for various boards use lowercase.
* Directory of config files for various boards use lowercase.
* CONFIG_BOARD uses uppercase.

This confuses the configuration scripts and leads to unintended overwriting of
.config, as well as missing of board-specific headers during compilation because
the include paths are case-sensitive.

This patch converts the default board names to lowercase to resolve such

5398c901f6 hv: remove CONFIG_PARTITION_MODE for pre-launched VM vE820 creation
Preparing for hybrid mode:

- create vE820 for pre-launched VMs and do other init code when the
  vm_config->type is PRE_LAUNCHED_VM.
- create ve820.c for each board because without wrapping by
  CONFIG_PARTITION_MODE, ve820_entry[] needs to be visible even when
  compiling target boards that haven't enabled pre-launched VMs.
- remove create_prelaunched_vm_e820() from vm.c and implement board
  specific function for each $(CONFIG_BOARD)/ve820.c. The reasons being:
  - don't need to define ve820_entry[32] for those boards that don't
    support pre-launched VMs.
  - more importantly, this makes it much easier to create different per-VM
    vE820 when it's needed.

This patch does the following cleanup:

- remove all hva2hpa()/hpa2hva() before calling enable_paging()

platform_acpi_info.h should be BOARD specific so move the header file
to configs/$(CONFIG_BOARD)/ folder.

So the target acpi info file detect process is:

Compiler search for $(CONFIG_BOARD)_acpi_info.h under
hypervisor/arch/x86/$(CONFIG_BOARD)/ first (the file is supposed to be
generated by offline tool so it is not included in original source), if
found, then the file is the target acpi info file. If not and at the
same time the ENFORCE_VALIDATED_ACPI_INFO Kconfig was set, the compiler
will stop and hint user to add target acpi info file by offline tool.
If ENFORCE_VALIDATED_ACPI_INFO was unset, then compiler will continue to
search for platform_acpi_info.h as target acpi info file under
hypervisor/arch/x86/$(CONFIG_BOARD) folder (with this file we could bypass
ENFORCE_VALIDATED_ACPI_INFO check and benifit for development). If this
file is not exist, then hypervisor/arch/x86/configs/platform_acpi_info.h
will be included as final target acpi info.

The process should work for UEFI path also, with a valid platform acpi
info file, S3/S5 should work on UEFI platform.

There are still some misra-c violations when CONFIG_PARTITION_MODE is defined.

arch/x86/configs:
- remove the unused macro: PRE_LAUNCH_VM_NUM
- pt_dev.c: VMx_CONFIG_PCI_PTDEV_NUM has been defined in partition_config.h,
  should not hard code them again in pt_dev.c.
- ve820.c: use "UL" suffix instead of "U" for 64 bits variables.

However, if the vmcall is undefined for a guest, RAX value of guest vcpu

According to SDM Vol. 3C 30-9, VMCALL is allowed from any CPL in guest.
VMCALL is NOT allowed from  CPL > 0 in vmx root mode.
ACRN hypervisor doesn't call VMCALL in vmx root mode, though.

In current code, ACRN also deny VMCALL from CPL > 0 in guest.
So for this case, #GP will not be injected, instead, modify the RAX to
