Dear all:
I try to cross-compile a program which runs standalone, no operating
system, on mips machine.
But the program is fulfilled with "malloc", which need c lib and
kernel support.
I know the implementation of malloc is quite complex and I want to
know does anyone have the same problem before o
yes thank a lot. This tutorial will be very usefull for me... I will send
you if i have any doubt regarding this...

yes you are right. I am lack of basic concepts. But i know this. I forget to
remember this. Anyway thank you...

I think u are lack of some basic concepts about kernel and kernel
module. u need read more Document about that.

When you get a module unrelated to the kernel distribution you should
place it in one of the version-independent directories under
/lib/modules.
And do u place them in the right place ?

Hi list,
I know that introducing/using new ioctls is frawned upon by the community.
They might still be needed for controlling various hw parameters, Just
wanted
to understand the data transfer side of ioctls with a use case.
E.g. My kernel module needs to pass a buffer of 1-2Mb to userspace
when
Read the USB specification firstly and Read the Document under the
kernel package,there is a folder where many documents input in about
hotplug ,ohci, ehci etc.

Hi List,
I am aware of the fact that in interrupt context one should not use
mutexes/semaphore
and should stick to spinlocks.
I am developing a module which exposes interfaces which could be called from
any/all
contexts. And I manipulate complex data structures in my functions. Being on
safer sid
