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.

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.

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.

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

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.

compiling target boards that haven't enabled pre-launched VMs.
- remove create_prelaunched_vm_e820() from vm.c and implement board

- don't need to define ve820_entry[32] for those boards that don't

feature. Eg.,
struct acrn_vm_config vm_configs[CONFIG_MAX_VM_NUM] = {
{
.guest_flags |= CLOS_REQUIRED,
.clos = 1,
},
};
sanitize_vm_config() will check if CAT is supported and

1) The previous implementaion will recalculate the whole EOI-exit bitmap for
each RTE once the destination, trigger mode, delivery mode or vector of a RTE
has changed and update the EOI-exit bitmap for each vcpu of the VM.
In this patch, only set the corresponding bit of EOI-exit bitmap for
a vcpu when a level triggered interrupt has accepted in IRR or clear the
corresponding bit of EOI-exit bitmap for a vcpu when a dege triggered interrupt
has accepted in IRR which means only update a bit of EOI-exit bitmap in a vcpu
when updating TMR.
2) Rename set eoi_exit related API to set eoi_exit_bitmap.

VMCALL is NOT allowed from CPL > 0 in vmx root mode.
ACRN hypervisor doesn't call VMCALL in vmx root mode, though.

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;

Add a API to sanitize vm_configs[] array, in this API, we will do sanity
check for VM configurations and refill some fields in vm_configs[]. If
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

This commit changes the EOI_EXIT_BITMAP as follows:
- add a eoi_exit_bitmap to vlapic structure;
- go through all the RTEs and set eoi_exit_bitmap in the vlapic structure when related RTE fields are modified;
- add ACRN_REQUEST_EOI_EXIT_UPDATE, if eoi_exit_bitmap changed, request the corresponding vcpu to write the bitmap
to VMCS.

Current ACRN implementation update TMR bits one time only when related RTE fields changed,
which is not acting like actual hardware.
From SDM vol3 10.8.4:
"Upon acceptance of an interrupt into the IRR, the corresponding TMR bit is cleared for
edge-triggered interrupts and set for leveltriggered interrupts."
This commit change the ACRN implementation to set/clear corresponding TMR bit when inject
intr to vlapic.
