Hi,
 Compile the kernel using kgcc.
I had a similar problem when I compiled the kernel with gcc.
It was fine when I recompiled using kgcc.

Madan.

I can boot up the system with this new image and run most of the
examples 
associated with the rtlinux. When I run the rtlcan driver, the system
hang. 
I know it got something to do with the interrupt but I got no ideas
where  
fault is.

Any ideas?

Thanks in advance.

I just tried it.  That's correct, at least for 2.91.66 and I believe all
"earlier" versions too.

IIRC, '\r' is defined as "white-space" and should be equivalent to a space.

 I may be wrong, but I believe the GNU compiler ignores \r in the source
 code.  The only place I've ever seen compilation fail because of \r is if
 the Makefile itself has \r in it.

Re: [rtl] A little of the subject -- But I need help

2001-03-27 Thread Patrick Maheral 

Hi Thomas,

Heres what I found about CVS and CR/LF in Win/DOS in the
"How to store binary files" node of the cvs info file:

There are two issues with using CVS to store binary files. The first is
that CVS by default convert line endings between the canonical form in
which they are stored in the repository (linefeed only), and the form
appropriate to the operating system in use on the client (for example,
carriage return followed by line feed for Windows NT).

It looks like CVS on the Win/DOS machine adds those ^M's as it receives the
files, and strips them before committing.  So, as long as you don't transfer
files directly between the the Win/Dos machines and unix machines (ie. ftp,
mail, copy, etc.), you should be OK.

I have been using CVS on a linux box for some time, and just recently added
some windows users.  We haven't had any problems with ^M's.  I just made
sure that the original files in the repository didn't have them to begin
with.

I hope that info is correct for your version of CVS.

Patrick

Re: [rtl] A little of the subject -- But I need help

2001-03-26 Thread Edgar Hilton 

If I remember correctly, in the newer WinCVS versions, there is an
option:

Admin-preferences 

tab which gives you the option of checking out ASCII files with the Unix
LF.  Check the box.  I believe that there is a more complete answer to
this at http://www.cvshome.org.

I hope that this helps.  If it doesn't, consider sending follow up
emails to the cvs mailing lists also listed in the website above.

bus mastering burst DMA.  I received two channels of word-size
(16-bits) data at 40Msps.  I would either average (4:1 low pass
filter) the data samples or shapshot (open aperature for
10Msps, close for 30Msps) data segments. The data acquisition
cards I used only support DMA transfers to contiguous memory
locations (old Altera FLEX10K PCI interface chips).  It would
have been better if I could have used "scatter/gather" DMA
(send number of memory blocks to the PCI chip and it returns an
array of non-contiguous virtual memory addresses).  Newer cards for a
follow-on, then I may be able to avoid the shared memory
for this purpose (I still think shared memory would be a cool
idea for a cluster).

I successfully employed 'lilo' using the 'append = 80M' option
to create a ~40MBy shared memory region.  All data transfers
populated a structure containing a HUGE array and some flags
(mutexes and semaphores).  I contemplated the 'bigphysarea' patch, but I
needed to access the memory from my real-time kernel module (I wrote an
tuneable power spectral density alogrithm that was loadable into the
kernel).  The shared memory pool fit the bill and I had no performance
impact on the rest of the Linux kernel.

Please feel free to contact me if you need additional information
([EMAIL PROTECTED]).  Real time Linux rocks! Real time Linux on the 2.4
kernel rocks++!

2000-11-14 Thread Dingrong Yi 

Hello everyone,

I have some questions concerning the communications between user space
program and the rtlinux program by fifo.

Consider such a scenerio, one rtlinux's program and one normal linux
program.  The rtlinux program  write to a fifo with
very high rate a structure,  and the fifo is created to be the same size
as that of the structure. The user program read the same structure from
that same fifo. 

What will happen that during the user program is reading from
the fifo when rtlinux program come  and take the resource over ? I can not
imagine how this issue be dealt with rtlinux. 

Another issue, consider again a rtlinux process, and a normal process.
This time the normal  process write a structure to a fifo and the rtlinux
read it. What will happen that when the linux process only write half of
the fifo when the rtlinux come to read it? 

Are such issues are considered already by rtlinux kernel or the user (like
me) of rtlinux should take care of it ?

Thanks

Dingrong

hello
i try to read data on a high speed serial port (moxa card at
500k bauds)
to do that i only use the outb and inb functions in my
module
i store 732 values in a table (unsigned char donnee[732])
when i have this 732 values i make a rtf_put() to be able to
read this data in my main program
in my cleanup() i make a vfree(donnee)

when my program try to stop the task i have this message and
there is a segmentation error and i can't rmmod my module

There is another important difference: Linux comes with  full  source
code,  you  don't  depend  on other people to help you - you can help
yourself by looking "how it's done".

With your problem, you could have found several examples how to build
modules from several object files in the kernel Makefiles.

But of course for a newbee it's difficult  to  know  where  to  start
looking.

   Hi guys,

  I have a question about the RTLinux architecture. I
know that both RTAI and RTL turn Linux as a task
running when no other RT task need the processor. The
thing is that I understand quite well the concept of
RTHAL used by RTAI but how RTL works ?

Greetings RTL/RTAIsters

What is the longest delay in clock ticks that can be given to
rt_task_make_periodic (2^32 ?) for the period argument?
What are some ways to produce longer periods?

Thanks,
Daniel

Hello rtl listees

Can one do realtime graphics (obvious restrictions of screen refresh rate 
aside) by simply writing to video memory in
ones RT kernel code. What happens when linux processes are then scheduled?

Thanks

Hi, everyone:

I have a question about the share memory use mmap. (in rtlinux-2.2)
I use the example in mmap, but what i want to know is is there is a 
limit of the size of share memory, for when i try to map a region
about 1000 int, in the kernel module the computer always dead.

Following is the program i use.

===
#include rtl.h
#include unistd.h
#include fcntl.h
#include sys/mman.h

//DATA * start;
int *start;
size_t length = 1000;
#define BASE_ADDRESS (96*0x10) 
//96Mb I have reserve the left 32Mb in lilo.conf

int init_module(void )
{
int i;

int fd = open("/dev/mem", O_RDWR);
if (fd  0) {
rtl_printf("failed to open /dev/mem\n");
return -1;
}
start = (int *)mmap(0,length*sizeof(int),PROT_READ|PROT_WRITE,
MAP_SHARED,fd,BASE_ADDRESS);
if (start == (int *) -1) {
rtl_printf("failed to map /dev/mem\n");
return -1;
}
rtl_printf("%p\n",start);
for (i = 0; i  1000; i++) {
rtl_printf ("%d\t",i);
start[i]=i;
rtl_printf ("%d\n", start[i]);
}
return 0;
}

void cleanup_module(void )
{
   munmap(start, length);
}

#ifndef MODULE 

int main(void)
{
if (init_module() == 0) {
cleanup_module();
}
return 0;
}
#endif
===

If i run this program in module, then the computer is dead.
If i run in user program, it's ok.

Anyone have some some suggestion about this?

Thanks in anvance.

Zhixu Liu

Hi, everyone:

I'm use linux2.2.14+rtlinux2.2 with only one CPU.

I'm trying to write a rt_driver for my camac 2915 pci device, first i just 
realize a open and a close interface (both only print out a open or close 
message). In my init_module, i use some pci routine to get the parameter 
of the 2915, print out. i use rtl_register_chrdev to register the 
rtdriver, then when i try to open the device in my another module, it 
just fail. Attach with the driver, can anyone give me some advice.

Thanks in anvance.

Hello:
I'am doing my thesis in based on Rtlinux. I have to map a file on memory to
that  rtilinux use it. My problem is how pass to rtlinux the memory address.
Proccess Linux pass to rtlinux the memory address where the file is mapped.
But, how do Linux convert this memory address to its address space?. 
I think that get_user must not work because in the register haven't be the
segment of process linux.
Excuse me for my poor English. This is in my speach:

 Buenas:
Estoy realizando un proyecto fin de carrera basado en linux. En el tengo que
mapear un fichero en memoria , para que lo use rtlinux. Mi problema está en
como pasar a rtlinux la dirección de memoria en la cual está mapeado.
Yo de momento le paso desde proceso Linux a rtlinux la dirección de memoria
donde está mapeado. Pero como convierte rtlinux esa dirección de memoria a su
espacio de direcicones?, ya que get_user no vale, por no estar en el
registro fp el segmento del proceso linux.

/*Linux proccess*/
pfichero=mmap(0,flength, PROT_READ,MAP_SHARED|MAP_LOCKED,fd,0);
/*Enviamos la dirección del fichero mapeado*/
 write(fifow,pfichero,sizeof(char*));

/*RTLinux proccess*/
rtf_get(FIFO_NUMW,pfichero,sizeof(char*))
How I access to mapped file?
