ACRN uses global invalidation for all DMAR translation caches. Whenever

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.

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

if data is generated faster than flushing by consumer. Capturing

This commit extend lapic pass-through for DM launched VM, generally for hard RT scenarios.
Similar to the partition mode, the vlapic is working under the xapic mode at first, only
when x2apic mode is enabled, lapic is passed through, because the physical LAPICs are
under x2apic mode.
Main changes includes:
- add is_lapic_pt() to check if a vm is created with lapic pt or not, to combine
codes of partition mode and DM launched vm with lapic passthrough, including:
- reuse the irq delievery function and rename it to dispatch_interrupt_lapic_pt();
- reuse switch_apicv_mode_x2apic();
- reuse ICR handling codes to avoid malicious IPI;
- intercept ICR/APICID/LDR msr access when lapic_pt;
- for vm with lapic passthrough, irq is always disabled under root mode.

Add a API to sanitize vm_configs[] array, in this API, we will do sanity

sanity check is failed, the HV would reject to boot.
About pcpu_bitmap of SOS_VM:
We should not hard code pcpu_bitmap for SOS_VM, this is not convenient for
unconfigured boards. The pcpu_bitmap follows a very simple rule:
All physical CPUs except ocuppied by Pre-launched VMs are all belong to
SOS_VM. In this way, the pcpu_bitmap of a SOS_VM is decided by pcpu_bitmap
status in PRE_LAUNCHED_VMs.
To get the correct pcpu_bitmap of SOS_VM, We need to setup another rule, that
the vm_configs[] array should follow the order of PRE_LAUNCHED_VM - SOS_VM
strictly.
With this patch enabled, the pcpu_bitmap field of sos vm config is not needed

SMRR (System-Management Range Register) is disabled from vMTRR,
so treat IA32_SMRR_PHYSBASE and IA32_SMRR_PHYSMASK as unsupported.
IA32_SMBASE is available only when IA32_VMX_MISC[15] is set.
IA32_FIXED_CTR0/1/2 are available only when CPUID.0AH:EDX[4:0] is non-zero.
Intel Processor Trace feature has been disabled and the associated MSRs
need to be in unsupported_msr[] as well.
