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

VM Name length is restricted to 32 characters. kata creates

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

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.

AcrnGT traps and intercepts the memory region defined by PCI bar in

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
boot failed issue.

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

triggered.
So negative errno is returned in order to terminate the initialization.

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.
