Hi Valdis,
Thank you for the reply.
I am not talking about all the variables. i am talking about variables
which are declared as module_param. These variables can anyways be changed
from shell prompt using echo and cat like i mentioned in the desciption. SO
i was hoping i can do it from drivers asw

Hi Luca
The locking mechanism to be used depends on what your piece of code does and
where your code runs.
If your code runs in a interrupt context (inside an interrupt handler), you
should use a spinlock (with irq save and restore).
Else you can use mutex or a semaphore.
In either cases, y

Hi all,
can someone please show me which is the best practice to lock a
read/write to a hardware register.
In other words if, in a driver, I want to modify a bit in a HW register,
I have to read the register, set/reset the relevant bit and write back
the reg.
But what can I do to be sure that no ot

Dear all,
I see that when we declare a variable as module_param from a driver, i can
see it listed in "/sys/module/xxx/parameters/...".
Ex : /sys/module/usbcore/parameters/autosuspend
we can modify and read it with echo and cat commands from terminal.
But is there a way i can read this value fr
