even i have written 2-3 mails to kernel newbies regarding this only ...but
no reply came :(
sending you that mail again if u can help --- that explains my problemin
even i am in the same boat ..
i am a web programmer by profession but want to change to linux kernel
programming so dont have any valid work ex
---i study in my spare time ---have done all those theoratical reading of
kernel from UTLK LKD LDD
have developed basic drivers too...
but when it

insmod my module the kernel hangs. On running with a remote gdb I
could figure out that
Count me in as well... I am also in a similar situation, have developed some
pseudo drivers and worked a bit on procfs. Looking for people to join me in
doing small projects.

Yes - Actually I need to wait for a device to finish something after
which I(device) error out. Ideally, I would like a simple
function using the standard apis that works on most kernels. I cannot
use jiffies as I mentioned earlier. Still working on it.

Hi Nidhi
Please use, plain text for writing mails to newbies, it does not
look good.
hi all
i was practising writing block device driver from linux device driver 3rd
edition
but was confused

I implemented a timer that can operate without interrupts. but it
relies on smp or smt.
what do you need it for ?

Dear all,
I have a question on the tun/tap module and the network-stack.
when we write a packet to:
tun_chr_aio_write, it will be transported to:
tun_get_user, it will be sent to the network-stack via:
netif_rx_ni to
netif_rx, where it will be handled by netpoll_rx.
if netpoll_rx returns true

I need it for a device. The device performs some operation in a loop
but I cannot wait in that loop forever, so I need to wait for the
maximum time I can (2 clock ticks) before giving up on the device.
Interrupts may be disabled so I cannot use jiffies. Any simple
solution would be appreciated.

Hello All,
Can you provide me with some project idea in file system that help to
understand file system stack.
Thanks

Hi Greg, Thanks for your reply.
Actually I am new to file system, I did work in memory management of Linux
kernel. My concern is to understand file system, block architecture etc. I
started reading, but wanted to do some implementation.
Thanks

u mean u wanna use the functions in your apps from user space?
if yes,u can write IOTRL command in the module for call the
functions, and in your app use iotrl system call send the command to
your module for doing sth you want,it is useful for communication with
modules.

oh sorry for my bad spelling. IOCTL not IOTRL .^-^
