I will be greatful for any criticism.
In short, i offload a processor and assign it a service.

i would suggest you schedule a tasklet. doing staff like from ISR ,
from my opinion
is too risky and bug prone.

Hi,
Many times i have come across a code which uses prepare_to_wait() as follows
:
>>>
up(&semaphore);

prepare_to_wait(queue, &wait, TASK_INTERRUPTIBLE);
if(condition())
schedule();
finish_wait(queue, &wait);

down_interruptible(&semaphore);

sorry, i am beginning to learn something new. never knew there is
such a system call vm86(). (man vm86 to read more), and the
implementation is in linux kernel's vm86.c, which runs 16bit under
32bit protected mode task.
and from the man pages of vm86, dosemu is using this API. So I think

technically, 16bit cannot access > 16bit of RAM for i368 CPU. so the
answer is technically impossible, CMIW.
and linux kernel only runs on 32bit and 64bit, but u want to execute
16bit insn? eg, using QEMU to run 16 bit application? So i think
your questions sounds like: how to execute insn

Hi All,
I am trying to send some information to User Space process from Kernel
Module/Driver. How can I do that in context of interrupt Service Routine?
I found that using kill_async, it is possible to send SIGIO signal and handling
that in User . Is there anyother way to achieve this ?

Hi, all
I want to enter v86 mode and switch to VGA Mode 13h to draw some pictures.
Now i can enter v86 mode with IRET instruction setting VM flag in the eflags
register.
But since v86 mode supports only 16-bit address, how can i let the cpu
executes instructions beyond 0x10 which includes set
Yes, yes, I know this will be a lot simpler in user-space, but, if i
trying to do this in kernel space, it is not because I'm masochist, but
because I need it. If this is not possible or, it is really too
difficult I will try to do otherwise, but I want to be sure before
changing my plans. Sa
