How to change user mode priority from kernel

NTDEV
1

Hi,
is there a way to change a given user mode
process base class and thread priority
from kernel ?

Is KeSetBasePriorityThread any help ?

2

why not just have the process or the administrator do this?

Hi,
I’m trying to design a sort of schduler
for a user mode process.
I plan to use the KeSetTimer in order to
achieve the kernel’s low latency and accuracy.

what I want to do in my timer routine is change
the user mode process priority, this way giving
it some slices with normal priority and some
with real time priority.

the user mode timing ability isnt good
enough in this case
how can I change the user mode’s process
priority from kernel (or any Ideas on the concept) ?

Why are
you trying
to do this?

And why do
you have to
indent your
questions, anyway?

The idea is to achieve some
real time features from this system
that is partialy third party

and regarding the indentation,
my monitor is placed too far
to the left, on my desk.
