hello BLUG buddies..
ive been facing some problem with interrupt Handling for a Network
Device Driver Program that im writing. The3 kernel gives a OOOPs
message saying Kernel Panic Not Syncing Interrupt and hangs. The code
is for  Realtek 8139 ethernet card..
the except of the Interrupt handling code is given below...
It would be really nice if someone could help me with the problem in
the peice of code..



void anich_interrupt_handler(int irq,void *dev_id,struct pt_regs
*regs)
  {
     struct net_device *dev = (struct net_device *)(dev_id);
     struct anich_priv *temp_priv;
     struct sk_buff *temp_buff = temp_priv->anich_skbuff;
     unsigned interrupt_value;
     long ioaddr = dev->base_addr;
      if(dev==NULL)               /* idf device is null the interrupt
cant be handled so return */
	 return;
      temp_priv = (struct anich_priv *) dev->priv;
     spin_lock(& temp_priv->lock);  /* lock the device */

     interrupt_value = Inb(ioaddr + ANICH_ISR);
			 if(interrupt_value & 0x0002)     /* 2nd bit
set indicates transmission ok*/

			   {temp_buff= temp_buff->next; /* moving to
next node when previous packet

		      was recieved successfully*/
                       anich_tx(temp_priv->anich_skbuff, dev);
		       }

		  if(interrupt_value & 0x0004)    /* 3rd bit set
indicates  transmission error */
			  anich_tx(temp_priv->anich_skbuff, dev);


		  if(interrupt_value & 0x0001)   /* 0th bit set
indicates receive OK */

anich_rx(dev, temp_priv->rx_packetlen,(char *) temp_priv-
>anich_skbuff);  /*????????*/
  Outb(0x00,ioaddr + ANICH_ISR);

return;

   }

ANICH_ISR is defined to the corresponding ioport region offset
address as indicated by the device data sheets

thanking you

Hello All,

I am trying to load a module using the insmod command. For some reason I get a
segmentation fault. Now the module is loaded as a "initializing" and if I try to
remove it using rmmod I get "Device or resource busy"

I have quiet a few of them now :-(

[root@CVSSERVER pci_scan]# lsmod
Module                  Size  Used by
t                       1824   1  (initializing)
test2                   1936   1  (initializing)
test1                   1904   1  (initializing)
test                    1184   1  (initializing)
DumpReg                 1120   1  (initializing)

Warm regards
Raghu.

comment the following line:

>      spin_lock(& temp_priv->lock);  /* lock the device */

Hi,
        Which of the C code coverage tool for linux is best ?
Where do i get GCT for download, does it come with RH distributions.
(I was unable to find any decent document on GCT after google search)
I browsed through the rpm but unable to find any rpm related to GCT.

Thanks
Karthik

You won't be able to unload the module as the module usage count is
onzero( 1, as shown by lsmod).
This is so because the module's init_module is faulty and is causing
segmentation fault while initializing.

The OOPS message indicates "An invalid dereferencing of a pointer has been
done" in the interrupt handler and
the kernel panics without syncing the filesystem buffers to the secondary
storage. In the code, temp_buff is initialized from uninitialized pointer
temp_priv...Could be the reason for panic..

Hi Karthik,

  You can use GCOV tool that comes along with linux.
For profiling u can use GPROF.
You have to give some compiler options to invoke this tool.
info pages has all the information abt the tools.
Thanks,
Pandi Chandran.

hi..
the problem is becuse of improper code of
init_module.. check that the MOD_INC_USE_COUNT is not
used in init or and error return value of function (
-ve return value ) is not handdled..

you wont be able to unload a module if it is being
used ( ie usage count > 0) as indicated by lsmod

Hi all

    I am trying out KDevelop for developing some GUI based application. In the
documentation I have seen code using a convention

QApplication a( argc, argv );

QPushButton hello( "Hello world!" );
hello.resize( 100, 30 );

a.setMainWidget( &&;hello );

connect(&&;hello, SIGNAL( clicked() ), &&;a, SLOT( quit() ));

In this, connect methode has got an unusual syntax like  "&&;hello". What does
it mean. connect methode has a prototype as following

bool connect ( const QObject * sender, const char * signal, const QObject *
receiver, const char * member )

   Can any one give some help .. ?

You would need to install the Mesa-devel package for this to work.

or if you have a NVIDIA card and are using their binary driver you'll have to
copy the header files from /usr/share/doc into the /usr/include/ to get the
software to compile.

hi  everybody !

                       i'am a student developing a voice chat and voice mail
application on linux -  i have some serious doubts about the effeciency  of the
voice mail server which i have designed . it is as below : (please note im
writing about the voice mail server)

1) As soon as a client  connects to the server - what i  did is i create a
thread using pthread_create( &thread , NULL,Handle_Connection(data), Data) ;

2) This function as it suggests takes care of all requests from the client until
the client indicates to exit - when he exits i call pthread_exit().

3) The function Handle_Connection()  calls Login_Request(), Register_Request(),
Store_Mail() ...etc accordingly as and when  requests come from the client.

4) In short each client is serviced by a seperate thread on the server .

My question is:

1) Is it efficient to create a new thread on the server to handle each client
request -it should be mentioned that i create just one thread for each client
for a session and when the client requests to log out - the thread exits .

  I would like to know your views on this design - and also be thankful for any 
suggestions for change in design .

I am using tcp for the connection  setup and tear down i know its an obvious
design flaw :-)  . so any suggestions keeping in mind this  would be helpful -
though i would also appreciate other  suggestions :-).

Thanks in advance .

best regards,

Amith Nambiar

Hi,

Don't worry, that's a mistake (maybe by the HTML viewer through which
you are viewing the documentation or something else).

It is,
a.setMainWidget( &hello );

The other strange '&&;' characters are also just '&'. That is passing
the address value held by the pointer.

hi!

normally when using a client server architecture, u use the fork()
call. the child created is use to handle new request. and using tcp
is not a brilliant idea, but u just make ur life easier.

Hi

   Thread mechanism is more than sufficient to handle multiple clients 
connecting.. instead if you are going for fork, it is a performance drop since
in case of fork a seperate process space is created and later it will land up in
so many processes running ...

   There is another way to handling multiple clients using select system call. in
this case only one thread is required for listening to multiple interfaces (
socket ) ..  then once data comes in any of the socket, you can decide to handle
the data in the same thread itself or spawn another thread for processing the
data .. here life time of the thread is very very small compared to the previous
one. that way system performance can be utilised even efficiently ..

     all depends on your load and processing criticality and all . so reach at a
better design ...

One more approach ...

Like in Apache server..

U can go for connection pooling.
i.e create say 50 processes (not threads in case of apache) in the beginning
Let each of them service one client at a time if the process is idle
Each process will not exit if client servicing is over....they will wait for
next request to come....
This connection pool can be of processes ot threads..

Hi

   Thread mechanism is more than sufficient to handle multiple clients
connecting.. instead if you are going for fork, it is a performance drop
since in case of fork a seperate process space is created and later it will
land up in so many processes running ...

   There is another way to handling multiple clients using select system call.
in this case only one thread is required for listening to multiple interfaces
( socket ) ..  then once data comes in any of the socket, you can decide to
handle the data in the same thread itself or spawn another thread for
processing the data .. here life time of the thread is very very small
compared to the previous one. that way system performance can be utilised
even efficiently ..

     all depends on your load and processing criticality and all . so reach at
a better design ...

Hi,

what about reading the source code for some PCI drivers?

Hi all

    I am using RH7.2 in my desktop. One of the most common problem I am facing is
with GUI. My Mozilla browser crashed many times ( more than IE.. ) so as to
loose all the navigated information. Here good thing is that I didn't have to
restart the system .. just had to kill the application and start a fresh one.
The point is that stability/performance of GUI system in Linux ( most UNIX like
systems ) are not at all apreciable ...  this is one main problem in deploying
the OS in home PCs I feel .. So for desktop kind of environment - where all
facilities/flexibility provided by X system is not required - , why can't we
think about a different stable GUI system.

What is the version of mozilla you are using? Mostlikely, It may
be a development version and therefore buggy. Try the latest
stable release version of mozilla. It is rock solid.

Mozilla might have crashed from reasons other than GUI, and in
any case xfree86 is quite bug free. In most of the cases, the
application crashes are not the fault of X
implementations, neither they are the fault of the widget system
used - they are due to some bugs in the application itself.

> X system is not required - , why can't we think about a

Xwindows is quite flexible. Granted, it may be a
little slow, but that has been a non issue for some time now.

Woah! Mozilla is about to release version 1.1, 1.0 came out months ago -
0.9.2.1 is totally ancient and unstable.

1.1 beta is better... faster rendering and the downloader works! and it has
Full-Screen mode!

Most importantly.. the entire application base would have to start from scratch!

Hello All,
I work in Linux PPC kernel. And I have an issue with a  "eepro100" network
driver that manages Intel 82559 NIC. It uses one function called
"pci_alloc_consistent" to allocate memory for a DMA Buffer. This memory gets
allocated at some 0xc000**** address.
But this depends upon the total amount of RAM in the system. I have board that
have 128MB, 256MB and 512MB of RAM.

This same allocation goes to locations 0xd* * * * * * * * , when the board is
detected to have RAM more than 128 MB. The result of this is the Network self
test fails.

Is there a way by which I can fix the DMA allocation area so specify it within a
range ??

Warm Regards,
Raghu.

Hi all

   I could download the same and it works fine now ...  cool ..

    regarding the GUI mechanism what I would like to say is, if at all it is not
performing well compared to the OTHER OSes, people will think twice to take it
as the first choice .. as far as a normal home user is concerned, performance in
terms of speed and good looks matters a lot ...  I do agree with the fact that
the whole application frame work may have to be changed if we need to go for a
new gui mechanism .. but still if we can find out - invent - a methode using
wich the older version and the "new" versions will work together, it will
revolutionise the picture of computing like any thing ...  that is where OTHER
operating systems are looking at .. to make "browsing" easy and good look and
feel experience ...  lay man doesn't care whether OS carries a message or not
... but if we can provide some thing which can deliver some thing more what
OTHERs provide.. it will be accepted like any thing ...

luv sgk
