In addition to a single OVMF image (OVMF.fd), split images
(OVMF_CODE.fd, OVMF_VARS.fd) can be used to facilitate VM management.
From the OVMF Whitepaper:
The variable store and the firmware executable are also available in
the build output as separate files entitled: "OVMF_VARS.fd" and
"OVMF_CODE.fd". This enables central management and updates of the
firmware executable, while each virtual machine can retain its own
variable store.
An example to launch acrn-dm with the split images:
--ovmf code=/usr/share/acrn/bios/OVMF_CODE.fd, \
vars=/usr/share/acrn/bios/OVMF_VARS.fd
v1 -> v2:
- use memory-mapped file I/O for writeback
- use fcntl to lock OVMF image files

Windows graphic driver obtains DSM address from in-BAR mmio register

pci configure space register which has virtualized. So TGL has to
keep identical mapping to avoid trap mmio BAR to do the emulation.
To keep simple, this patch hardcode the TGL DSM region in vE820
table, this will cause memory waste here. In the near future, we
need refine the entire vE820 logic as it is hard to maintained

a) If the MMIO device only has MMIO regions and no ACPI Table touched, using

b) If the MMIO device touches ACPI Table, using "--acpidev_pt HID"
Now only support TPM2 MSFT0101 MMIO device pass through through launch script
using "--acpidev_pt MSFT0101". When we want to pass through the TPM2 deivce,
we would not allow to emulate the vTPM2 at the same time. This is becuase

Besides, we could only support one TPM2 device PT and one MMIO device PT.

we could pass through the MMIO resources on the cmdline.

There're some PCI devices need special handler for vendor-specical feature or
capability CFG access. The Intel GPU is one of them. In order to keep the ACRN-HV
clean, we want to throw the qurik part of PCI CFG asccess to DM to handle.
To achieve this, we implement per-device policy base on whether it needs quirk handler
for a VM: each device could configure as "quirk pass through device" or not. For a
"quirk pass through device", we will handle the general part in HV and the quirk part
in DM. For a non "quirk pass through device", we will handle all the part in HV.

set the attributes during pm-vuart initialization
to avoid the pm-vuart in an indefinite state.
Currently we have implemented S5 triggered by SOS,
these patch series both support S5 triggered by SOS and RTVM.
the fully steps for S5 triggered by SOS:
1) S5-Trigger: it initiates the platform shutdown actions;
it calls “acrnctl stop vmX” to do that,
and check the VM's status, power-off SOS itself.
2) acrnctl will send “stop” to “acrn-dm”
3) acrn-dm will send “shutdown” command to VMx by v-UART.
4) when life-cycle manager in VMx receives the “shutdown” command,
it will give an “acked” to acrn-dm, and then poweroff itself.
the fully steps for S5 triggered by RTVM:
1) S5-Trigger in RTVM: it initiates the platform shutdown actions;
it’ll send shutdown command for platform shutdown to
life-cycle manager
2) when life-cycle manager in RTVM receive the message,
it will send “shutdown” command to acrn-dm in SOS by v-UART.
3) when acrn-dm receives the “shutdown” command from RTVM,
it will give an “acked” to RTVM, RTVM’s life-cycle manager can
power off itself
4) acrn-dm will send “shutdown” command to its own life-cycle manager
by socket.
5) when life-cycle manager in SOS receives the “shutdown” command,
it can call “s5_trigger” script to shutdown platform.

In order to add GVT-D support, we need pass through stolen memory and opregion memroy
to the post-launched VM. To implement this, we first reserve the GPA for stolen memory
and opregion memory through post-launched VM e820 table. Then we would build EPT mapping
between the GPA and the stolen memory and opregion memory real HPA. The last, we need to
return the GPA to post-launched VM if it wants to read the stolen memory and opregion
memory address and prevent post-launched VM to write the stolen memory and opregion memory
address register for now.
We do the GPA reserve and GPA to HPA EPT mapping in ACRN-DM and the stolen memory and
opregion memory CFG space register access emulation in ACRN-HV.

In this case, we could handle all the passthrough PCI devices in ACRN hypervisor.
But we still need DM to initialize BAR resources and Intx for passthrough PCI
device for post-launched VM since these informations should been filled into
ACPI tables. So
1. we add a HC vm_assign_pcidev to pass the extra informations to replace the old
vm_assign_ptdev.
2. we saso remove HC vm_set_ptdev_msix_info since it could been setted by the post-launched
VM now same as SOS.
3. remove vm_map_ptdev_mmio call for PTDev in DM since ACRN hypervisor will handle these
BAR access.
4. the most important thing is to trap PCI configure space access for PTDev in HV for
post-launched VM and bypass the virtual PCI device configure space access to DM.
This patch doesn't do the clean work. Will do it in the next patch.
