Summary:
- I noticed that virtio-blk and FAT are not enabled for some
virt configurations.
- This commit enables them for testing.
Impact:
- None
Testing:
- Tested with qemu-7.1
- NOTE: file copy with rv-virt:knetnsh64 is sometimes unstable.

Summary:
- I noticed that arm64_gic_raise_sgi() is not implemented for
GICv2 which is used for SMP + hypervisor such as qemu + kvm.
- This commit fixes this issue
Impact:
- None
Testing:
- Tested with qemu-7.1 + kvm (linux) and qemu-7.1 + hvf (macOS)

Summary:
- I noticed that pcsi version can not be obtained with qemu + kvm.
- Also, pci_detect hangs with qemu + hvf.
- This commit fixes this issue by using hvc (hypervisor call).
Impact:
- None
Testing:
- Tested with qemu-7.1 + kvm (linux) and qemu-7.1 + hvf (macOS)

Summary:
- During testing with qemu + kvm, I noticed that nuttx hangs
when setting cntfrq_el0. With qemu + kvm, it starts from
EL1 because we can not specify virtualization=on
- However, I noticed that it works without setting cntfrq_el0
- This commit fixes this issue
Impact:
- None
Testing:
- Tested with qemu-7.1 (both with kvm and without kvm)
- NOTE: to work with kvm, GICv2 must be used.

Testing for overflow by adding a value to a variable to see if it "wraps
around" works only for unsigned integer values, because signed overflow
has undefined behavior according to the C and C++ standards.

Changes the executable type built against the `make export` target fully linked by default. This greatly improves performance when loading applications, as relocations no longer need to be processed.
This change allows boards to define an additional kconfig option, which specifies the final link format of application executables.
By selecting `CONFIG_BINFMT_ELF_RELOCATABLE`, and providing an appropriate linker script, applications can be fully linked, removing the need to process relocations.
The following warning is emitted when building with GCC 12.2.0:
"the comparison will always evaluate as ‘true’ for the address of ‘g_parm’ will never be NULL [-Waddress]"
As g_param is an array of char[]. each member should have an actual address, so the validation in each if statement is not required.
Allows boards to supply their own gnu-elf linker script, used when building Nuttx applications and CONFIG_BUILD_KERNEL.
This is useful when building fully-linked applications (see #9395).
pthread_cond_wait() should be an atomic operation in the mutex lock/unlock.
Since the sched_lock() has been wrongly deleted in the previous commit,
the context switch will occurred after the mutex was unlocked:
--------------------------------------------------------------------
Task1(Priority 100) | Task2(Priority 101)
|
pthread_mutex_lock(mutex); |
| |
pthread_cond_wait(cond, mutex) |
| | |
| | |
| ->enter_critical_section() |
| ->pthread_mutex_give(mutex) | ----> pthread_mutex_lock(mutex); // contex switch to high priority task
| | pthread_cond_signal(cond); // signal before wait
| | <---- pthread_mutex_unlock(mutex); // switch back to original task
| ->pthread_sem_take(cond->sem)| // try to wait the signal, Deadlock.
| ->leave_critical_section() |
|
| ->pthread_mutex_take(mutex) |
| |
pthread_mutex_lock(mutex); |
---------------------------------------------------------------------
This PR will bring back sched_lock()/sched_unlock() to avoid context switch to ensure atomicity

LED effects must be implemented in the lower-half of the LED driver.
The interface is designed to supports the following LED effects:
- intenisty (PWM)
- Bling (Timer)
- Fade in, Fade out (Ramp)
The udp connection structure contains the field, "domain", which defines which address family it belongs to. Prior to this change, this field was only populated correctly if IPv4 and IPv6 was enabled. As a result, packet information was not processed in udp_recvpktinfo, as expected when the appropriate socket option was enabled.
1. the killpg function can make all the
ltp/open_posix_testsuite/killpg testcaes passed
2. Nuttx do not support process group, so we use kill process instead
3. the implementation are referred to:

In the default configuration, the Litex ethernet peripheral contains two RX and two TX buffers. The active buffer for the peripheral should be swapped as soon as possible, in order to reduce packet loss.
This modification acknowledges the receive buffer as soon as the pending data is copied into the NuttX device data buffer. Improving reliability under heavy load.
