In this patch, add vuart configuration in scenario XML of
each board to support communication between service VM and
user VM since system shutdown feature need to send commands
through this vuart communication channel.
The follow changes are made in this patch:
- Add multi legacy vuart for service VM for communication
- Add one legacy vuart for user VM for communication
- Add 8250.nr_uarts parameter in command line of service OS

In lock instruction emulation, we use vcpu_make_request and
signal_event pairs to shoot down/release other vcpus.
However, vcpu_make_request is async and does not guarantee an execution
of wait_event on target vcpu, and we want wait_event to be consistent
with signal_event.
Consider following scenarios:
1, When target vcpu's state has not yet turned to VCPU_RUNNING,
vcpu_make_request on ACRN_REQUEST_SPLIT_LOCK does not make sense, and will
not result in wait_event.
2, When target vcpu is already requested on ACRN_REQUEST_SPLIT_LOCK (i.e., the
corresponding bit in pending_req is set) but not yet handled,
the vcpu_make_request call does not result in wait_event as 1 bit is not
enough to cache multiple requests.
This patch tries to add checks in vcpu_kick_lock_instr_emulation and
vcpu_complete_lock_instr_emulation to resolve these issues.

Commit 4a04fcc ("config_tools: skip remapping HW units with no devices under
scope") skips hardware remapping units without any device under its scope in the
config tools, which turns out to only work if the HV is not parsing the DMAR at
runtime.
This patch reverts the previous workaround and fixes the previous issue by
always initializing `dmar_hw_list.hw_ignore` when parsing DMAR. This ensures
that the DRHDx_IGNORE macro will always be emitted while DRHD_COUNT is not
impacted.

Implement the write_vcbm() function to handle the

Call write_vclosid() to handle MSR_IA32_PQR_ASSOC MSR write request
Several vCAT P2V (physical to virtual) and V2P (virtual to physical)

struct acrn_vm_config *vm_config = get_vm_config(vm_id)
max_pcbm = vm_config->max_type_pcbm (type: l2 or l3)
mask_shift = ffs64(max_pcbm)

pmsr = MSR_IA32_type_MASK_0 + pclosid
pcbm = vcbm << mask_shift
vcbm = pcbm >> mask_shift
Where
MSR_IA32_type_MASK_n: L2 or L3 mask msr address for CLOSIDn, from
0C90H through 0D8FH (inclusive).
max_pcbm: a bitmask that selects all the physical cache ways assigned to the VM
vclosid: virtual CLOSID, always starts from 0
pclosid: corresponding physical CLOSID for a given vclosid
vmsr: virtual msr address, passed to vCAT handlers by the

pmsr: physical msr address

Fix a crash in the 'board_inspector.py' tool in case 'cpuid' is not
installed on the system.
The tools crashes because 'cpuid' is used before the check for
dependencies is done in the code. That check for dependencies is
done in the 'legacy/board_parser.py' file. But the native_check()
function that is called before it also expects the cpuid tool to
be installed.
The fix is to move the check for dependencies in the main
'board_inspector.py' file, before any other operation is done.
