Sir,
i have completed read, write operation in character driver, using semaphore,ioctl. Also implementing kernel timer.
How can we access directory thorough a c program?
Question is to write a program to find all the files with ext ‘.txt’ in a current directory.
so, How can we access a directory? or any hint …
When I list the processes executing on my system it displays many kworker/ processes with interruptible sleep (waiting for an event to complete) , an unknown value of tty and many different pids (even if my system is idle).
Also when I execute “top” it does not display any entry of kworker.
I am using fedora 16_64bit and 3.4.9-1.fc16.x86_64 kernel.
Can anyone please explain what kworker is/does? Why are there so many entries for kworker processes in the process status table?
Successfully implemented block driver with ioctl and request function.
On initialisation the block driver is running the request function four times and all the requests that are coming are to read the data.
Dear Friends,
I Have Successfully Run 508 Clients in my project without using any SLEEP in server or client , But when I am trying to Run More Clients than this i got an error
“multiply: error while loading shared libraries: libc.so.6: cannot open shared object file:Error24″
Today i learned how to save file descriptor, how to use PIPE.
i implement IPC with one requesting client and one processing client.
but one doubt here that either server should run the client or client should run the server ?
I’ve implemented IPC using pipes.
Implemented multiple byte transfer using serial port successfully.
Implemented nibble mode,byte mode successfully, and successfully move a string from peripheral to computer in nibble mode.
