Zide Chen 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.

Zide Chen 518a82d80b hv: cleanup some hva/hpa conversion code
The init page tables installed in either cpu_primary.S or trampoline.S
are 1:1 mapping and won't be changed in the future.

The 'actual' hypervisor page table installed in enable_paging() is 1:1
mapping currently but it could be changed in the future. Both hva2hpa() and
hpa2hva() are implemented based on these page tables and can't be used
when the init page tables take effect.

This patch does the following cleanup:

- remove all hva2hpa()/hpa2hva() before calling enable_paging()
- get_hv_image_base() returns HVA, not HPA. So add hva2hpa() for all cases
  that are called afte enable_paging().

Victor Sun 649406b049 HV: refine location of platform_acpi_info header
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.

Zide Chen 94e1227559 hv: code style fix for partition mode specific code
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.

vmid is uint16_t in ACRN, so vuart_vmid should be uint16_t as well.

Fix another few other miscellaneous misra-c violations.

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.

Yan, Like 17f4cd18a3 hv: fix dest of IPI for CPU with lapic_pt
With lapic_pt based on vlapic, guest always see vitual apic_id.
We need to convert the virtual apic_id from guest to physical apic_id
before writing ICR.

SMP for VM with lapic_pt is supported with this fix.

Yan, Like e2cecfb560 hv: send IPI instead of irq injection to notify vcpu with lapic pt
For VM with local apic pt for realtime scenatios, we support virtio device with PMD backend.
But we still need to inject MSI to notify the front-end, to avoid changing the front-end drivers.

Since the lapic is passed through, irq injection to vlapic won't work.
This commit fix it by sending IPI with vector need to inject.
