d325966612 board_inspector: always defer parsing of method bodies
The current ACPI AML parser can generate incorrect AST if a DSDT/SSDT
satisfies the following:

  1. The body of a method invokes a NameString that is defined later.

  2. Before that method the same NameString is also defined but in an outer
     scope and with a different number of parameter.

Since method bodies hardly define any further symbol that is referenced
outside the method itself, this patch forces the parsing of method bodies
to be deferred to the second pass when all symbols have been declared.

60920bb905 board_inspector: Access I/O registers on-demand and properly
The current implementation of I/O buffers have the following issues.

  1. I/O buffers are filled with values on creation. This may be fine for
     memory-mapped I/O regions, but could be a problem to port I/O regions
     and indexed I/O regions.

  2. While not commonly seen, it IS witnessed that some devices only allow
     its MMIO registers to be accessed with certain width. Accessing such
     registers with a larger width will not be handled by the device,
     causing SW to get all 1's rather than the actual values in these
     registers.

This patch resolves the issues above as follows:

  1. I/O buffers now do not access any register on creation. Instead, the
     register is accessed only upon requests.

  2. The access width of these registers are followed to ensure that the
     registers are accessed properly.

The classes that represents buffers when interpreting AML is also
refactored to abstract the common code that manages fields within
buffers. The class hierarchy now looks like this:

  BufferBase: Implement methods that registers, reads or writes fields
    Buffer(BufferBase): Implement memory buffer
    StreamIOBuffer(BufferBase): Implement I/Os available via /dev files
    IndexedIOBuffer(BufferBase): Implement I/Os via index/data registers

Currently the HV console does not support PCI UART with 64bit BAR, but in the

d1d59437ea HV: vm_load: correct needed size of bzImage kernel
The previous code did not load bzImage start from protected mode part, result
in the protected mode part un-align with kernel_alignment field and then cause
kernel decompression start from a later aligned address. In this case we had
to enlarge the needed size of bzImage kernel to kernel_init_size plus double
size of kernel_alignment.

With loading issue of bzImage protected mode part fixed, the kernel needed size
is corrected in this patch.

2b5bd2e87a HV: vm_load: load protected mode code only for bzImage
When LaaG boots with bzImage module file, only protected mode code need
to be loaded to guest space since the VM will boot from protected mode
directly. Futhermore, per Linux boot protocol the protected mode code
better to be aligned with kernel_alignment field in zeropage, otherwise
kernel will take time to do "rep movs" to the aligned address.

In previous code, the bzImage is loaded to the address where aligned with
kernel_alignment, this would make the protected mode code unalign with
kernel_alignment. If the kernel is configured with CONFIG_RELOCATABLE=n,
the guest would not boot. This patch fixed this issue.

69fef2e685 hv: debug: Add hv console callback to VM-exit event
In some scenarios (e.g., nested) where lapic-pt is enabled for a vcpu
running on a pcpu hosting console timer, the hv console will be
inaccessible.

This patch adds the console callback to every VM-exit event so that the
console can still be somewhat functional under such circumstance.

Since this is VM-exit driven, the VM-exit/second can be low in certain
cases (e.g., idle or running stress workload). In extreme cases where
the guest panics/hangs, there will be no VM-exits at all.

In most cases, the shell is laggy but functional (probably enough for
debugging purpose).

553d59644b HV: Fix decode_instruction() trigger #UD for emulating UC-lock
When ACRN uses decode_instruction to emulate split-lock/uc-lock
instruction, It is actually a try-decode to see if it is XCHG.
If the instruction is XCHG instruction, ACRN must emulate it
(inject #PF if it is triggered) with peer VCPUs paused, and advance
the guest IP. If the instruction is a LOCK prefixed instruction
with accessing the UC memory, ACRN Halted the peer VCPUs, and
advance the IP to skip the LOCK prefix, and then let the VCPU
Executes one instruction by enabling IRQ Windows vm-exit. For
other cases, ACRN injects the exception back to VCPU without
emulating it.
So change the API to decode_instruction(vcpu, bool full_decode),
when full_decode is true, the API does same thing as before. When
full_decode is false, the different is if decode_instruction() meet unknown
instruction, will keep return = -1 and do not inject #UD. We can use
this to distinguish that an #UD has been skipped, and need inject #AC/#GP back.

9e7abbb38c dm: Use new MMIO device passthrough management ioctls
IC_ASSIGN_MMIODEV	->	ACRN_IOCTL_ASSIGN_MMIODEV
IC_DEASSIGN_MMIODEV	->	ACRN_IOCTL_DEASSIGN_MMIODEV

struct acrn_mmiodev has slight change. Move struct acrn_mmiodev into
acrn_common.h because it is used by both DM and HV.
