We don't reserve PCI MMIO in e820 Table, it's included in DSDT ACPI Table.
About 0xA0000 - 0x100000 entry, we don't have any ACPI Table touch this region.
So we could remove it too.
After this change, we could only pass the reserved e820 table which we must
reserve to OVMF. In this case, the OVMF could trust ACRN-DM and pass the
reserved e820 table to guest instead of dropping it.
This patch needs the corresponding modify in OVMF. Otherwise, the guest could

The current design has the following problem:
gvt uses some pci bar regions,
but ACRN-DM isn't aware of these regions.
So ACRN-DM may allocate these regions for other pci devices,
which will result in other pci devices bar regions
overlap with gvt bar regions.
The new design is the following:
(1) ACRN-DM reads gvt bar regions
which are provided by physical gpu;
(2) ACRN-DM reserves gvt bar regions
v6 -> v7:
* use array to store reserved bar regions
* rename some struct and func
v5 -> v6:
* rename enable_gvt to gvt_enabled
* add a interface to reserve bar regions
* reserve gvt bar regions

The Block Event Interrupt (BEI) bit in the TRB descriptor could
delay the triggering of interrupt. For most OSes, the native
driver for xHCI will use this bit to optimize the IO performence,
due to reduction of number of interrupts.
But in Linux, the native xHCI driver for Intel brand controller
doesn't use this bit. It is fine for the native scenario due to
most work is completed by hardware. But in virtualization scenario,
it is almost impossible to support heavy data IO such as high
resolution video recording (ISOC transfer).
Hence, this issue is solved by a 'quirk' when the intel hardware is
emulated (when vendor id is set as 0x8086). For other cases, a
virtal hardware called 'ACRN xHCI' is emulated, and both Linux and
Windows will use BEI bit by default.

PCI spec says that the procedure of sizing a BAR is as follows:
1) disable the decode via command register
2) save the original value of BAR register
3) write all-1 to the BAR register
4) read BAR register back, calculate the size
5) restore the original value to BAR register
6) re-enable the decode via command register
Some driver does not disable the decode of BAR register via the
command register before sizing a BAR. This will lead to a overlay
of the BAR addresses when trying to register the intermediate
BAR address via register_bar. A stateful variable sizing is used
to keep track of such kind of BAR address changes and workaroud

AcrnGT traps and intercepts the memory region defined by PCI bar in
service OS kernel driver. No need to register the bar associated region
in dm. By the way, some OS changes BAR start address and there is no
mechanism to reflect the gvt changes back to dm. It causes problem that
other devices may register new region which falls in GVT `old` region,
and leads to hypervisor crash.
v4: Add FIXME tag. It's a short term solution before migrated to OVMF
v3: rewording the comments
v2: removed unnecessary braces and use printf to log (Peter)

This patch adds support to trigger rescan of virtio-blk device by the
guest VM. This is an alternate to hot-plugging virtio-blk device.
This feature stems from the kata requirement, which hot-plugs container
rootfs after the VM is launched.
As part of virtio-blk rescan,
1. Update the backing file for the virtio-blk device with valid file.
Basically update the empty file (with dummy bctxt) that was passed
during VM launch.
2. Update virtio-blk device configurations for udpated backing file.
3. Update size associated with valid backing file in the config space.
4. Notify guest OS, of the new config change.
5. On this notification, guest will do the following.
(i). Update virtio-blk capacity.
(ii). Revalidate the disk.
(iii). Identify the newly plugged block device.
v5 -> v6:
- Removed use of dummy file and added a new parameter "nodisk"
to virtio-blk which indicates user wants to create a virtio-blk
device with dummy backend.
- Moved vm_monitor_rescan from pci core to virtio-blk as it currently
applies to only virtio-blk.
v4 -> v5:
- Reverted back logic, so that blkrescan is only supported when
VM is launched with empty backend file.
v3 -> v4:
- Close block context before allocating a new one
- Allow backend filepath with additional options to be more generic
- Remove blank lines introduced as part of previous patches.
v2 -> v3:
- Renamed vdev ops vdev_blk rescan to vdev_rescan
- Renamed montior ops virtio_blkrescan_ops to virtio_rescan_ops
- Consolidated virtio-blk configuration specific part into
a separate function
- Removed size requirement in acrnctl command.
v1 -> v2:
- Added more comments in the code.
- Renamed APIs from displug to blkrescan, inline with acrnctl cmd.
- Split the patch into two. This corresponds to changes in acrn-dm.

ACRN interepts vm_set/reset_ptdev_intx_info hypercalls to set
the SOS vdev properties to indicate it is assigned to UOS. Today,
upon vm_reset_ptdev_intx_info hypercall ACRN does not revert the SOS
vdev properties back to that of SOS, as vbdf and pbdf were not
part of the API. This would leave ACRN data structures in an incorrect
state

When UOS set failling irq type, gpio BE will only request GPIOEVENT_REQUEST_FAILLING_EDGE
event from native gpio driver which will cause the last_level value is always 0.
So last_level can't be used to check whether interrupt should be injected or not.
It is the same for rising irq type.
v2: refine commit message.

When the "i915.enable_gvt=0" is added for SOS kernel boot args, ACRN-DM will
fail in course of gvt initialization and errno is returned directly.
As the errno defined in linux/errno.h is positive, it will continue
the unexpected initialization in ACRN-DM and then the segment fault is
triggered.
So negative errno is returned in order to terminate the initialization.

Guest OS for example Windows will disable bars before shutdown. Bars
are unregistered when they are disabled. Trying to unregister a bar
which has been unregistered causes a assertion. In pci_emul_free_bars
only those enabled bars should be unregistered.
