ptrdiff_t is defined as intptr_t that is defined as _ssize_t in Nuttx.
The real size depends on architecture and the PTR_MAX and PTR_MIN is
specified by it.
the application can access the remote cpu touch driver by
rpmsgdev, so the defines and struct will be used even if not
enable the CONFIG_INPUT/CONFIG_INPUT_TOUCHSCREEN.

Use the flag (COP_FLAG_UPDATE)structure member to mark
whether it is just input data.
like this:
can do manys times,just input data
....
cryp.ses = session.ses;
cryp.op = COP_ENCRYPT;
cryp.src = (caddr_t) s;
cryp.len = len;
cryp.flags = COP_FLAG_UPDATE;
cryp.dst = 0;
cryp.mac = (caddr_t) out;
cryp.iv = 0;
if (ioctl(cryptodev_fd, CIOCCRYPT, &cryp) == -1)
{
warn("CIOCCRYPT");
goto err;
}
can do manys times like frist...
then,the last time
Don't use any flay structure member to mark
this is last time,need get final result
....
cryp.ses = session.ses;
cryp.op = COP_ENCRYPT;
cryp.src = (caddr_t) s;
cryp.len = len;
cryp.flags = 0;
cryp.dst = 0;
cryp.mac = (caddr_t) out;
cryp.iv = 0;
if (ioctl(cryptodev_fd, CIOCCRYPT, &cryp) == -1)
{
warn("CIOCCRYPT");
goto err;
}
....
that will get last result.

The memalign is special to multiple mempool because multiple mempool
doesn't support split and shrink chunk operate. So When you alloc a
memory block and find an aligned address in this block, you need to
occupy 8 bytes before the address to save the address of the padding
size and pool to ensure correct use in realloc and free operations.
So we will use bit1 in the previous address of the address to represent
that it is applied by memalign.

This delta describes the relationship between the block size of each
mempool in multiple mempool by user initialized. It is automatically
detected by the mempool_multiple_init function. If the delta is not
equal to 0, the block size of the pool in the multiple mempool is an
arithmetic progressions, otherwise it is an increasing progressions.

Let's specify size instead of number, so that we can unify the size of

The dependency should be vice versa; the MM_SHM should depend on the
existence of the virtual memory range allocator.
Create a new CONFIG flag CONFIG_ARCH_VMA_MAPPING, which will define that
there is a virtual memory range allocator. Make MM_SHM select that flag

Replace static gs_vaddr with a new dynamic mapping list. Collecting all
this kind of virtual memory mappings into a single structure makes

The task_group specific list can be used to store information about
mmappings.
For a driver or filesystem performing mmap can also enable munmap by
adding an item to this list using mm_map_add(). The item is then
returned in the corresponding munmap call.

When the signal sent by the sender is blocked in the target task,
if the target task has an action registered with sa_flags SA_KENELHAND,
it will directly respond to the action in the context of the sender.
When the action is executed, it will have the parameters set by the
target task with sigaction:sa_user.

_assert is a kernel procedure, entered via system call to make the core
dump in privileged mode.
Running exit() from this context is not OK as it runs the registered
exit functions and flushes streams, which must not be done
from privileged mode as it is a security hole.
Thus, implement assert() into user space (again) and remove the exit()
call from the kernel procedure.
This is preparation for flushing streams from user space, like it should
be done.
- Move tg_streamlist (group, kernel space) ->
ta_streamlist (TLS, user space)
- Access stream list via tg_info in kernel
- Access stream list via TLS in user space
- Remove / rename nxsched_get_streams -> lib_getstreams
- Remove system call for nxsched_get_streams
