Subject: Hytec 5331 CAMAC kernel 2.6 driver problem 
GrŁezi,

I am new to this list.
We are using MIDAS in the Muonic Hydrogen Lamb Shift experiment at PSI. Previously the DAQ was maintained by Paul Knowles. For the upcoming beamtime I took over.

Now I have problems with the kernel driver khyt1331_26 with Midas svn 3315.

I have compiled the driver, and modprobe khyt1331 works.
Then: "cat /proc/khyt1331" gives, with the CAMAC crate switched OFF:

Hytec 5331 card found at address 0xCC40, using interrupt 10
Device not in use
CAMAC crate 0: not responding
CAMAC crate 1: not responding
CAMAC crate 2: not responding
CAMAC crate 3: not responding


When I switch the crate on and do the "cat" again, the computer freezes.
When I switch the crate OFF again, the computer screen turns black and the computer beeps.


Is anybody using the Hytec 5331 PCI CAMAC card plus the Hytec 1331 CAMAC crate controller and can help me?

I would greatly appreciate any help. Otherwise I am lost.

Cheers,

Randolf

------------------------------------------------------
Using SuSE 9.3 on a P4. Tried HyterThreading on and off.
uname -a:
Linux mpq1p13 2.6.11.4-21.13-smp #1 SMP Mon Jul 17 09:21:59 UTC 2006 i686 i686 i386 GNU/Linux

------------------------------------------------------
This is exactly what I did (my logbook):
> cd $MIDASSYS/drivers/kernel/khyt1331_26
edit kyt1331.c:
replace (line 36):
# include <config/modversions.h>
with
# include <linux/config.h>
now
> make
> make install
Works, but produces irrelevant error:
install: cannot stat `../doc/*.9': No such file or directory
(Some doc stuff missing)
Finish "make install" by hand by typing
> /sbin/depmod

Load the driver and check it is there:
> modprobe khyt1331
> lsmod | grep khyt
gives on my machine:
"khyt1331 13084 0 "

Now try
> cat /proc/khyt1331

Gives on my machine (no CAMAC crate attached)
Hytec 5331 card found at address 0xCC40, using interrupt 10
Device not in use
CAMAC crate 0: not responding
CAMAC crate 1: not responding
CAMAC crate 2: not responding
CAMAC crate 3: not responding

Finally we need the character device with major number 60 ("char-major-60)
called "/dev/camac".
First check that no device with major=60 exitst:
> ls -l /dev | grep "60,"
should not produce any output.
So we create this device by
> mknod /dev/camac c 60 0
And
> ls -l /dev | grep "60,"
results in
crw-r--r-- 1 root root 60, 0 2006-09-01 14:25 camac

(Here start the problems described above. I had the same problems when I tried the "cat" with CAMAC on BEFORE I did the "mknod")

----------------------------------------------------------
Uncommenting all "prink" in ../drivers/kernel/khyt1331_26/khyt1331.c I get the following kernel logs in /var/log/messages:

Sep 1 17:15:59 mpq1p13 kernel: khyt1331: ioctl 3, param 3

And then it dies.
