virtio is a framework to implement the virtio drivers
vhost (Virtual Host) is a framework to implement the virtio devices
With the virtio and vhost framework, we can use the virtio drivers
and vhost drivers to implement the cross-core communication.

The feature depends on ARCH_USE_SEPARATED_SECTION
the different memory area has different access speed and cache
capability, so the arch can custom allocate them based on
section names to achieve performance optimization

reason:
Currently, if we need to schedule a task to another CPU, we have to completely halt the other CPU,
manipulate the scheduling linked list, and then resume the operation of that CPU. This process is both time-consuming and unnecessary.
During this process, both the current CPU and the target CPU are inevitably subjected to busyloop.
The improved strategy is to simply send a cross-core interrupt to the target CPU.
The current CPU continues to run while the target CPU responds to the interrupt, eliminating the certainty of a busyloop occurring.

reason:
when a context switch occurs, up_switch_context is executed.
In order to reduce the time taken for context switching,
we inline the up_switch_context function.

When monitoring multiple capture channels, the `ioctl` function
is called three times, leading to significant overhead mainly due
to VFS and `nxmutex_lock/unlock`. Adding a new interface can save
the overhead of two `ioctl` calls.

Summary:
1.Modified the i_crefs from int16_t to atomic_int
2.Modified the i_crefs add, delete, read, and initialize interfaces to atomic operations
The purpose of this change is to avoid deadlock in cross-core scenarios, where A Core blocks B Core’s request for a write operation to A Core when A Core requests a read operation to B Core.

to trigger flush, and the call will be returned immediately.

However, the flush implementation is asynchronous, when all the flush
