The version info is mainly used to tell the user when and where the binary is
compiled and built, this will change the hv version format.
The hv follows the format:
major.minor-stable/unstable-remote_branch-acrn-commit_date-commit_id-dirty
DBG/REL(tag-current_commit_id) scenario@board build by author date.
The '(tag-current_commit_id)' is optional, it exits only when there are
tags for current commit.
e.g.
with tag:
ACRN:\>version
HV: 3.1-stable-release_3.1-2022-09-27-11:15:42-7fad37e02-dirty DBG(tag: v3.1)

Improve SMP call to support ACRN shell to operate RTVM.
before, the RTVM CPU can't be kicked off by notification IPI,
so some shell commands can't support it, like rdmsr/wrmsr,
memory/registers dump. So INIT will be used for RTVM, which
LAPIC is pass-thru.

In 'get_ptdev_info()', variables 'bdf' and 'vbdf' are

to 32bit pointers when calling 'get_entry_info()'.
This mismatch causes insufficient space when storing

With current arch design the UUID is used to identify ACRN VMs,
all VM configurations must be deployed with given UUIDs at build time.
For post-launched VMs, end user must use UUID as acrn-dm parameter
to launch specified user VM. This is not friendly for end users
that they have to look up the pre-configured UUID before launching VM,
and then can only launch the VM which its UUID in the pre-configured UUID
list,otherwise the launch will fail.Another side, VM name is much straight
forward for end user to identify VMs, whereas the VM name defined
in launch script has not been passed to hypervisor VM configuration
so it is not consistent with the VM name when user list VM
in hypervisor shell, this would confuse user a lot.
This patch will resolve these issues by removing UUID as VM identifier
and use VM name instead:
1. Hypervisor will check the VM name duplication during VM creation time
to make sure the VM name is unique.
2. If the VM name passed from acrn-dm matches one of pre-configured
VM configurations, the corresponding VM will be launched,
we call it static configured VM.
If there is no matching found, hypervisor will try to allocate one
unused VM configuration slot for this VM with given VM name and get it
run if VM number does not reach CONFIG_MAX_VM_NUM,
we will call it dynamic configured VM.
3. For dynamic configured VMs, we need a guest flag to identify them
because the VM configuration need to be destroyed
when it is shutdown or creation failed.
v7->v8:
-- rename is_static_vm_configured to is_static_configured_vm
-- only set DM owned guest_flags in hcall_create_vm
-- add check dynamic flag in get_unused_vmid
v6->v7:
-- refine get_vmid_by_name, return the first matching vm_id
-- the GUEST_FLAG_STATIC_VM is added to identify the static or
dynamic VM, the offline tool will set this flag for
all the pre-defined VMs.
-- only clear name field for dynamic VM instead of clear entire
vm_config

MADT is used to specify the GSI base for each IO-APIC and the number of
interrupt pins per IO-APIC is programmed into Max. Redir. Entry register of
that IO-APIC.
On platforms with multiple IO-APICs, there can be holes in the GSI space.
For example, on a platform with 2 IO-APICs, the following configuration has
a hole (from 24 to 31) in the GSI space.
IO-APIC 1: GSI base - 0, number of pins - 24
IO-APIC 2: GSI base - 32, number of pins - 8
This patch also adjusts the size for variables used to represent the total
number of IO-APICs on the system from uint16_t to uint8_t as the ACPI MADT
uses only 8-bits to indicate the unique IO-APIC IDs.

GSI is a better way to represent physical and virtual INTx interrupt
source.
1) This patch replaces usage of "pin" with "gsi" whereever applicable
across the modules.
2) PIC pin to gsi is trickier and needs to consider the usage of
"Interrupt Source Override" structure in ACPI for the corresponding VM.

strncpy_s(d, dmax, s, slen): the 'dmax' includes the null terminator, while
slen doesn't. Thus if (dmax == slen == strlen(s)), strncpy_s() chooses to
discard the last character from s and instead write '\0' to d[dmax - 1].
strnlen_s(s, maxsize): if there is no terminating null character in the
first maxsize characters pointed to by s, strnlen_s() returns maxsize.
So in the following example or similar cases, we need to increase the size
of d[] by 1 to accommodate the null terminator, and add '1' to the dmax
argument to strncpy_s().
uint8_t d[MAX_LEN];
size = strnlen_s(s, MAX_LEN);
