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.

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.

For Linux kernel, the UART driver will disable IER.THRE. But for Windows, it
will keep IER.THRE turn on then cause interrupt storm.
From pc16550d UART spec, INTR PIN description:
"Interrupt. This pin goes high whenever any one of the following interrupt types
has an active high condition and is enabled through the IER Receiver Error Flag;
Received Data Available timeout (FIFO Mode only); Transmitter Holding Register
Empty; and MODEM Status. The INTR signal is reset low upon the appropriate
interrupt service or a Master Reset operation."
And Interrupt Reset Control of Transmitter Holding Register Empty Interrupt
description:
"Reading the IIR Register (if source of interrupt) or Writing into
the Transmitter Holding Register"
The datasheet hasn't describe very clear if the THRE interrupt will be
re-generate after "Reading the IIR Register". We assume it will not do
that, so the THRE interrupt only generate when THR turn to empty.
This patch follows above assumption to resolve the interrupt storm cause WaaG

mmio_hint in mem.c can potentially be accessed concurrently in
emulate_mem() because it only holds a read lock. Use a local variable to
make sure the same entry address is used throughout the function. Since
it only serves as a hint, it's okay if the function does not use the
most up-to-date version of mmio_hint, as long as mmio_hint is accessed
atomically.
Explicitly enforce natural alignment on mmio_hint to guarantee atomic
accesses on x86 and increase code portability, even though compilers
most likely always do it.
Entries in the RB tree are only removed in unregister_mem_int() while
holding a write lock, so accessing mmio_hint while holding a read lock
is safe.

virtio_rnd_get_entropy():

OVMF requires a more descriptive mechanism than RTC CMOS to retrieve
ACRN's memory layout, so we now pass the E820 map to it, starting at
0xEF000 (ROM area).
ACRN currently uses [4GB, 5GB) as its 64-bit PCI host aperture. This is
inconsistent with OVMF's assumption of its platform's memory layout,
because it derives the size of high memory from RTC CMOS, which is
incapable of describing the 64-bit PCI hole.
By default, OVMF uses RTC CMOS 0x5b/0x5c/0x5d to determine the size of
high memory. This value only tells OVMF how much memory is above 4GB,
but not the platform's memory layout above 4GB.
Using RTC CMOS works for QEMU, because QEMU places its 64-bit PCI host
aperture above its highmem. Therefore, OVMF can always assume highmem is
located at [4GB, 4GB + highmem), which is not where ACRN's highmem is
located. For example, if we have 1GB of usable memory above 4GB, ACRN
will place it at [5GB, 6GB).
This change allows OVMF to correctly identify the guest's memory layout.
It will consider any reserved region above 4GB as 64-bit PCI host
aperture.
MP table, SMBIOS and ACPI tables are all located above 0xF0000 so it is
guaranteed that there is no overlap. There can only be a maximum of 128
E820 entries.
v1 -> v2:
- provide more explanation to this commit
- add signature before E820 map for OVMF backward compatibility

Without memory barrier, the change of used ring index could not

For virtio-blk FE driver, when it receives an interrupt, and confirms the
used ring index has changed, it will first set ring flags with
VRING_AVAIL_F_NO_INTERRUPT, then get buffer from virtqueue, after
process this request, it will mask VRING_AVAIL_F_NO_INTERRUPT, and get
used ring index again before return. If used ring changes, it will
process it. At the same time, BE will read this flags before each notify,
if VRING_AVAIL_F_NO_INTERRUPT was set, BE will not inject interrupt.
Without memory barrier, before FE mask VRING_AVAIL_F_NO_INTERRUPT, BE
has finished notify without interrupt, then FE mask
VRING_AVAIL_F_NO_INTERRUPT, and get used ring index but failed (index
has changed from BE side). FE will return from interrupt handler
function, and wait for next interrupt which was not injected by BE. Thus,
this will cause kernel hung.

Currently, the emulation of pci msi/msix can be handled by hypervisor code.
The logic in dm passthru driver can be simplified.
This patch remaps msix table to usersapce in DM passthru driver.
1. The access to the msix table in passthru driver will be trapped, and emulated by hv code.
2. The access to the config space in passthru driver will be trapped, and emulated by hv code.
So dm passthru driver no longer needs to keep the whole logic of handling msi/msix.
No need to do msix table remapping in sos kernel.

Support DISCARD command is meaningful when eMMC usage is high or
there are lots of remove operations. For example, when Guest
Android is running, there will be lots of files being created and
removed. However, virtio-blk BE does not support DISCARD command,
data remove operation in UOS will not trigger erase in eMMC. After
period of time, the eMMC will be consumed out, and erase must be
done by eMMC firmware before writing any new data. This causes the
eMMC performance decrease in the whole system (SOS and UOS).
To solve the problem, DISCARD should be supported in virtio-blk BE.

On Intel Apllo Lake platform, the VBus will drop after the SOC suspended,
hence during the SOS resuming process, there will be a disconnecting event
and a connecting event sent to each native USB device in order.
This patch will use new strategy for S3 resuming emultion.
1. The DM set PORTSC register to 'no device attached' state when S3
suspending started,
2. SOS resuming starts and do nothing for device disconnecting event,
3. 'Cache' device connecting event and don't report it to UOS,
4. UOS believe no device attached due to PORTSC register state and
begin to clear the resource allocated for the device before S3
suspending,
5. DM receives the Disable Slot command from UOS and report the 'cached'
device connecting event to UOS, hence trigger the emulation behavior
for the device.
The purpose of this strategy is to let UOS resuming proceed as quickly as
possible, which means the UI will be turned on quickly to user.

This patch uses a periodic timer to give backends pseudo notifications
so that drive them processing data in their virtqueues. People should
choose a appropriate notification peroid interval to use this poll
mode. Too big interval may cause virtqueue processing latency while
too small interval may cause high SOS CPU usage. The suggested interval
is between 100us to 1ms.
The poll mode is not enabled by default and traditional trap

This patch introduce a new mode of IO request completion, polling mode.
Now, the sketch of ioreq process can be,
A. UOS vcpu0 generate PIO/MMIO ->
B. pcpu1(vcpu0 of UOS) trap into HV ->
C. pcpu1 build ioreq, send IPI and enter idle ->
D.1 pcpu0(vcpu0 of SOS) response IPI,
D.2 pcpu0 handle the ioreq in HV, kernel, DM,
D.3 pcpu0 mark ioreq as complete,
D.4 pcpu0 hypercall to enter HV ->
E.1 pcpu0 send IPI to wake pcpu1 up
E.2 UOS vcpu0 continue running
With this change, it skips D.4, E.1 steps. In step C, pcpu1 will enter a
polling ioreq state idle after send out the IPI.
It can save about ~5000 cpu cycles.
In polling mode, we do the polling in idle instead of pause cpu all the
time. It will consume more power. A better way is to use monitor/mwait
instructions which can put cpu into a sleep state with monitoring a
memory address. Unfortunately, APL has bug with monitor. We can gather
all ioreqs state into one monitorable memory and take advantage of
monitor/mwait for future platform.
The way polling or notification is per VM. We can config VMs in
different mode. By default, IO request completion will use notification
mode for all VMs. We can switch it by Kconfig.

this patch fixes such an information leaking issue:
in case that after a UOS is destroyed, its memroy
will be reclaimed and maybe re-allocated for a new UOS,
then the previous UOS sensitive data in memory may
be leaked to the new UOS.

The /dev/vbs_ipu is used by the backend driver of IPU mediator on SOS kernel
If the file of /dev/vbs_ipu exists, it indicates that IPU works in mediator mode.
Other it will fall back to the pass-through mode.
But the commit 969f7cf071 doesn't check the file of /dev/vbs_ipu correctly.
It should be -e instead of -f.

At devicemodel/hw/uart_core.c, struct ttyfd has only one file
descriptor for uart backend device, that is OK if DM uart open
a tty characteor device under /dev/ for reading, writing and
terminal operating.
When use stdio as backend tty device, there are 2 fds, stdin/stdout.
DM should read from 'stdin' and output to 'stdout'. But ttyfd just
has one fd, and is only for 'stdin', so dm has to output to stdin,
too, not to stdout.
That cause a problem: if use stdio for uart backend, you can't
redirect UOS console to any other files. Because stdout is not used.
We hope to store information from VM console to system journal,
when UOS is launched by Acrnd automatically. The systemd need to
redirect stdout of dm to system journal files, but it can't be done.
So we can split the 'fd' of struct ttyfd to 'fd_in' & 'fd_out'.
they are same when use tty device; And they are different when use
stdio, 'fd_in' is for stdin and 'fd_out' is for stdout.

(EV_MSC, MSC_TIMESTAMP) is added to each frame just before the
SYN event since kernel 4.15. EV_MSC is configured as
INPUT_PASS_TO_ALL. In the use case of virtio-input, there is
a loop as follows:
- A mt frame with (EV_MSC, MSC_TIMESTAMP) is passed to FE.
- FE will call virtinput_status to pass (EV_MSC, MSC_TIMESTAMP)
back to BE.
- BE writes this event to evdev. Because (EV_MSC, MSC_TIMESTAMP)
is configured as INPUT_PASS_TO_ALL, it will be written into
the event buffer of evdev then be read out by BE without
SYN followed.
- Each mt frame will introduce one (EV_MSC, MSC_TIMESTAMP).
Later the frame becomes larger and larger...
This patch fixed above issue by ignoring MSC_TIMESTAMP from guest.
Besides that timestamp is added for every status event from guest
before writing to evdev.
