In the process of USB data transfer, there three kinds of data blocks:
a. Non data block, which contains some control information;
b. Partial data block, which contains part of a large data chunk;
c. Full data block, which contains a complete data chunk.
In previous implementation, the differences mentioned above are described
by the usb_block::chained. But the 'chained' is concept in the xHCI area
and should not appear in the USB layer. This patch introduces enum type
usb_block_type to replace the 'chained' field in struct usb_block.

It doesn't check if a client is connected and can result in ENOTCONN
with virtio-console backend being reset. This will prevent client
connection at a later point. To avoid this, ignore ENOTCONN error.
PS: For Kata, the runtime first launches VM and then proxy which acts

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
this violation.
Currently this issue is only found when audio device is passed
through to Windows 10 guest. When it is fixed in the Windows
audio driver, this patch should be reverted.

Currently, we use STR_LEN for all checking the size of all the

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.

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

"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

The datasheet hasn't describe very clear if the THRE interrupt will be

that, so the THRE interrupt only generate when THR turn to empty.

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

Per debugging requirement, map the watchdog reset to warm reset.
So the ramconsole could be used to capture the kernel log of UOS
before watchdog is hit.

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.

There is a deadlock when emulate_mem is called on the memory region
of PCI extended configuration space. The call trace is something like:
emulate_mem
-> pci_emul_ecfg_handler
-> pci_cfgrw
-> pci_emul_cmdsts_write
-> unregister_bar/register_bar
-> modify_bar_registration
-> unregister_mem/register_mem
mmio_rwlock is hold in emulate_mem when calling unregister_mem/
register_mem which is trying to acquire mmio_rwlock again, and deadlock
happened.
It is possible that bar address is changed just between a on-going
MMIO access which can bring a race condition in theroy. Guest needs to
take care of the serial operation between bar addess update and MMIO
access of that bar.

Sometimes guest OS writes PCIR_COMMAND register to disable the device,
then update the bar address followed by a write to PCIR_COMMAND register
to enable the device again. In this case unregister_bar/register_bar
should be called otherwise the IO/MMIO regions monitored by device model
will not be updated accordingly.

This patch adds the support of inet socket as the backend of uart
emulation. Data written by guest uart is transferred to a socket and
data from socket is forwarded to guest uart. This enables something
called "Uart Over TCP" which is useful in some case such as WinDbg
connection over uart. The command line syntax is as follows:
-l comX,tcp:port_number
