Get the platform EPC resource and partiton the EPC resource for VMs
according to VM configurations.
Don't support sgx capability in SOS VM.
init_sgx is called during platform bsp initialization.
If init_sgx() fails, consider it as configuration error, panic the system.
init_sgx() fails if one of the following happens when at least one VM requests
EPC resource if no enough EPC resource for all VMs.
No further check if sgx is not supported by platform or not opted-in in BIOS,
just disable SGX support for VMs.

VM Name length is restricted to 32 characters. kata creates
a VM name with GUID added as a part of VM name making it around
80 characters. So increasing this size to 128.
v1->v2:
It turns out that MAX_VM_OS_NAME_LEN usage in DM and HV are for
different use cases. So removing the macro from acrn_common.h.
Definied macro MAX_VMNAME_LEN for DM purposes in dm.h. Retaining
original macron name MAX_VM_OS_NAME_LEN for HV purposes but defined

Currently, we use STR_LEN for all checking the size of all the
acrn-dm parameters. But some parameters like kernel boot args
can grow based on different needs. For example, when kata launches
guest VM using acrn, the kernel boot args increases by 256 bytes
(i.e 1024 +256).
Just increasing STR_LEN will unnecessarily increase allocations
for other acrn-dm parameters. So decoupling only boot_args
length and increasing it to 2048.
PS: If other parameters like ramdisk path, kernel path,
elf_path etc. don't need 1024 bytes, we can reduce STR_LEN
to 256 or 512 bytes.

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.

Given all Broxton family share same port IO Cx data, we use a unified

The previous function just check the pstate target value in PERF_CTL msr
by indexing px data control value which comes from ACPI table, this would
bring a bug in the case that guest is running intel_pstate_driver:
the turbo pstate target value from intel_pstate driver is in a range
instead of fixed value in ACPI _PSS table, thus the turbo px request would
be rejected. This patch fixed this issue.

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.
