  611   03 Aug 2009 Konstantin OlchanskiForumHow to distinguish the status and value returned from "mvme_read_value(...)"
> uint32_t mvme_read_value(MVME_INTERFACE * vme, mvme_addr_t vme_addr);
> Question: How to distinguish the status and value returned?

On VME interfaces using the Universe and tsi148 PCI-VME bridges, your question has no meaning.

The VME address space is directly mapped into the PCI address space, then mmap()ed into your 
program address space. Internally mvme_read_value() is "return *(uint32_t*)(mmap_base + vme_addr);" 
and there is no such thing as "status".

Physically on the VME bus, for single-word VME cycles (mvme_read_value), there are only 2 error 
conditions, an AS or a DS timeout, and these bridges return the bit pattern 0xFFFFFFFF for either error, 
the same as the traditional VME bus always worked (i.e. before PCI, before ISA, back when the VME bus 
*was* the main CPU-memory-IO bus).

So the answer to your question is "yes". If mvme_read_value() returned 0xFFFFFFFF, there was a VME 
bus timeout because the board you are trying to address a) is not installed, b) was unplugged, c) does 
not decode the address you tried to access (maybe you used the wrong AM code or the wrong data 
width).

With Universe and tsi148 PCI-VME bridges, the mvme_read() call runs the DMA interface that can issue 
block transfer cycles on the VME bus. These DMA interfaces have interesting error handling, but 
basically, they only tell you the estimated VME address at which the AS or DS timeout or BERR has 
occurred. For sane VME boards, DMA errors mean very basic breakage of the VME crate and VME board.

With non-directly attached VME interfaces, i.e. the SIS3100, you can also have communication errors. I 
do not know how those are reported by the SIS3100 Linux drivers, and I do not know how the MIDAS 
driver reports them. But I do know that if you see those errors, your interface is very broken and VME 
bus errors are the least of your worries.

P.S. There also exist PCI bus errors, they also return the bit pattern 0xFFFFFFFF and mean basic 
breakage inside your computer. PCI-PCI and PCI-host bridges have special registers you can read to 
find out the exact cause of the error ("your computer is broken").

  612   04 Aug 2009 Exaos LeeForumVME-related codes contribution
Hi, all

I have some codes while using MIDAS. I upload them here. They are tested with
SIS3100. I haven't other VME controllers, so I don't know whether they work with
other controllers. I just hope that they are helpful. You may find information
from the file "00README.txt" in the package vme4midas.zip. My English is limited, I just hope
that you may catch my ideas. Smile

All my best.

  613   04 Aug 2009 Exaos LeeForumScripts to handle MIDAS sessions
Hi, all again

I have some scripts in "bash" and "Python" to handle MIDAS sessions. Please see the attached utils4midas.zip. I didn't write instructions in detail of how to use them. But I think they are very simple. You may find how to use them by reading the codes and example files.

Best wishes.

  614   04 Aug 2009 Exaos LeeForumAbout python interface
Coding in Python is faster than in C (but running slower). So, some python interfaces are useful for testing purpose. I hope you may like the PyMVME module for VME bus testing.

As requested from K.O., I paste the "00README.txt" as the following:

** PyMVME module

   The module "PyMVME" provides the following stuff:
      a. class StdVME
      	 -- contains standard VME informations.
      b. class MVME_INTERFACE
      	 -- the C structure MVME_INTERFACE wrapped in Python
      c. dict MVME_STATUS
      	 -- the return information defined in "mvmestd.h"
      d. the related useful aliases from "mvmestd.h"
      	 -- including "mvme_addr_t", "mvme_locaddr_t", "mvme_size_t"
      e. class MvmeDev
      	 -- the major class which provides methods to access VME bus.

   You may find examples of how to use module "PyMVME" from "find_caen.py" or
   scripts in dir "test". All of the examples are using "lib_sis3100mvme.so".
   You may find information later in this introduction.

** find_caen.py

   The script to find VME modules from CAEN. Now, it is still in test status
   and can only find ADCs, TDCs or QDCs.

* SIS3100 library to be used togather with "mvmestd.h"

  The directory "sis3100" contains sources to build libraries as the following:
  a. lib_sis3100.a     -- APIs declared in "sis3100_vme_calls.h"
  b. lib_sis3100mvme.a -- APIs declared in "mvmestd.h". It also contains the
     		       	  same APIs from lib_sis3100.a

  If you want to use shared libraries, especially when you are using utilities
  wrote in Python, you may rebuild the libraries as the following:

    $ cd sis3100
    $ make shared

* APIs to handle VME modules

** vadc_caen.h/c

   Provides APIs to handle ADC-type modules from CAEN, including:
      a. ADCs --- V785, V785N
      b. TDCs --- V775, V775N
      c. QDCs --- V792, V792N

* VME bus testers

  Still under development.
  619   21 Aug 2009 Exaos LeeForumLink error of "mcnaf"
The "utils/mcnaf.c" uses "camop()",
180:         printf("camop\n");
181:         camop();
But "drivers/camac/camacrpc.c" provides "cam_op()":
void cam_op()
{
}

If you compile each source into an object, you may encounter a link error as
mcnaf.c:(.text+0x3b1): undefined reference to `camop'
collect2: ld returned 1 exit status
The "mcstd.h" provides "camop". So, we need to change "camacrpc.c" to match the definition and fix the link error.

> If you compile each source into an object, you may encounter a link error ...

Also camac rpc did not work at all last time we tried to use it at triumf, maybe 4 month ago in the Dragon 
experiment (upgrade from older version of midas). Never got around to trace down why. YMMV.

  621   29 Aug 2009 Exaos LeeForumAt last, I'm here again!
I always got a 503 server error while I tried to connect this log book the latest 
weeks. I don't know why. I hope it is not due to the network censorship because 
of the coming National Day of China. Anyway, good luck to me when I want to paste 
something here.
  622   31 Aug 2009 Exaos LeeForumLink error of "mcnaf"
I repeated the link error again. I also found the almost all sources located in "driver/camac/" using "cam_op()" but not "camop()". Please see the grep result below:
drivers/camac/camaclx.c:760:INLINE void cam_op()
drivers/camac/camacnul.c:200:INLINE void cam_op()
drivers/camac/camacrpc.c:563:void cam_op()
drivers/camac/cc7700pci.c:744:INLINE void cam_op()
drivers/camac/ces2117.c:227:void cam_op()
drivers/camac/ces8210.c:553:void cam_op(void)
drivers/camac/ces8210.c:576:    cam_op();
drivers/camac/ces8210.c:625:    cam_op();
drivers/camac/dsp004.c:692:void cam_op()
drivers/camac/hyt1331.c:1125:INLINE void cam_op()
drivers/camac/jorway73a.c:563:INLINE void cam_op()
drivers/camac/kcs2926.c:618:INLINE void cam_op()
drivers/camac/kcs2927.c:677:INLINE void cam_op()
drivers/camac/wecc32.c:554:INLINE void cam_op()

I also found why the default Makefile can pass away this problem. I found the "make" using the following command to compile the "mcnaf":
cc -g -O3 -Wall -Wuninitialized -Iinclude -Idrivers -I../mxml -Llinux/lib -DINCLUDE_FTPLIB   -D_LARGEFILE64_SOURCE -DHAVE_MYSQL -I/usr/include/mysql -DHAVE_ODBC -DHAVE_ZLIB -DOS_LINUX -fPIC -Wno-unused-function -o linux/bin/mcnaf utils/mcnaf.c drivers/camac/camacrpc.c linux/lib/libmidas.a -lutil -lpthread -lodbc -lz
I try to re-implement the link error again. So I wrote some test code.

1. anullf.h
#ifndef _ANULLF_H_
#define _ANULLF_H_ 1

#define EXTERNAL extern

#if defined( _MSC_VER )
#define INLINE __inline
#elif defined(__GNUC__)
#define INLINE __inline__
#else
#define INLINE
#endif
/* make functions under WinNT dll exportable */
#if defined(_MSC_VER) && defined(MIDAS_DLL)
#define EXPRT __declspec(dllexport)
#else
#define EXPRT
#endif

EXTERNAL INLINE void EXPRT camop() {  };

#endif

2. ma_1.c
#include "anullf.h"

void cam_op() {}

3. ma.c
#include "anullf.h"
#include <stdio.h>

int main(int argc, char** argv)
{
  camop();
}

Then, only compiling as below can pass:
$ gcc -O -o ma ma_1.c ma.c
If you remove the option "-O", compiling immediately fails in a link error. Whether you compile into objects then link them or just compile them together, you can pass with option "-O" or the similar options. It is because the compile could solve linking to a dummy function automatically with option "-O".

Anyway, we should fix this no matter changing the "mcstd.h" or codes located in "driver/camac/".

There are many "INLINE" definitions in "include/*.h". Both GNU C and C99 permit using inline functions. I still wonder why. Smile
  624   01 Sep 2009 Jimmy NgaiForumTimeout during run transition
Dear All,

I'm using SL5 and MIDAS rev 4528. Occasionally, when I stop a run in odbedit, 
a timeout would occur: 
[midas.c:9496:rpc_client_call,ERROR] rpc timeout after 121 sec, routine 
= "rc_transition", host = "computerB", connection closed
Error: Unknown error 504 from client 'Frontend' on host computerB

This error seems to be random without any reason or pattern. After this error 
occurs, I cannot start or stop any run. Sometime restarting MIDAS can bring 
the system working again, but sometime not.

Another transition timeout occurs after I change any ODB value using the web 
interface:
[midas.c:8291:rpc_client_connect,ERROR] timeout on receive remote computer 
info: 
[midas.c:3642:cm_transition,ERROR] cannot connect to client "Frontend" on host 
computerB, port 36255, status 503
Error: Cannot connect to client 'Frontend'

This error is reproducible: start run -> change ODB value within webpage -> 
stop run -> timeout!

Any idea?

Thanks,
Jimmy

A few hints for debugging:

- do the run stop via odbedit and the "-v" flag, like

[local:Online:R]/> stop -v

then you see which computer is contacted when.

- Then put some debugging code into your front-end end_of_run() routine at the 
beginning and the end of that routine, so you see when it's executed and how long 
this takes. If you do lots of things in your EOR routine, this could maybe cause a 
timeout.

- Then make sure that cm_yield() in mfe.c is called periodically by putting some 
debugging code there. This function checks for any network message, such as the 
stop command from odbedit. If you trigger event readout has an endless loop for 
example, cm_yield() will never be called and any transition will timeout.

- Make sure that not 100% CPU is used on your frontend. Some OSes have problems 
handling incoming network connections if the CPU is completely used of if 
input/output operations are too heavy.

The INLINE statements are a relict from times where a subroutine call was in the order of a few microseconds. This was when you probably were pretty young, and we had MS DOS PCs running at 66 MHz and 640 kB (not MB!) of memory. At that time, inlining the CAMAC functions gave a 50% speedup, believe it or not! I guess now this is completely obsolete, plus modern compilers can do inlining automatically if they realize that there is a benefit. So we should remove all the inline business. We plan some major rework later in September, so I will include that on the todo list there.

  641   07 Sep 2009 Exaos LeeForumdeprecated conversion from string constant to ‘char*’
I encountered many warning while building MIDAS (svn r4556). Please see the
attached log file. Most of them are caused by type conversion from string to
"char*".
Though I can ignore all the warning without any problem, I still hate to see
them. :-)

  642   09 Sep 2009 Jimmy NgaiForumRetrieve start/stop time in offline
Hi All,

I set "/Analyzer/ODB Load" to true and analyzed a run in offline mode. After
that, I found the start time and stop time in /RunInfo did not reflect the
correct time as in online. How do I retrieve the correct start/stop time from
the ODB in offline mode?

Thanks!

Jimmy

Most trees in the ODB are not loaded with "/Analyzer/ODB Load", since you might 
want to have the start/stop time of the offline analysis there for example 
(although I agree that the online start/stop time is more interesting). So you 
have several options:

- modify mana.c. There is a function odb_load(), which first locks the whole ODB 
and then unprotects "/Experiment/Run Parameters" for example. Just add three more 
lines for "/Runinfo".

- write a run summary when running online. After each run, write a summary with 
start/stop time, number of events, settings etc. into some file. I usually do this 
in the EOR routine of the online analyzer and write directly into a CSV file which 
I can import directly into Excel. There I can make filtering depending on certain 
parameters, like show me all runs with more than x events where setting y was 10.

- extract the ODB from the .mid file with "odbhist -e filename.mid" and look into 
that.

- The time stamp of each event is in UNIX time form (seconds since 1.1.1970), so 
you now exactly when each event was recorded.

Hope one of this helps...

- Stefan

There is no "type conversions". The compiler is whining about code like this:

/* data type names */
static char *tid_name[] = {
   "NULL",
   "BYTE",
   ...

I guess we should keep the compiler happy and make them "static const char*".

BTW, my compiler is SL5.2 gcc-4.1.2 and it does not complain. What's your compiler?

K.O.

When I use "make" with odbedit, the generated "experim.h" also contains such codes as:
#define EXPCVADC_COMMON_STR(_name) char *_name[] = {\
"[.]",\
...
This will cause "type conversion" warnings. I hope that "odbedit" can generate codes like this:
#define EXPCVADC_COMMON_STR(_name) const char *_name[] = {\
"[.]",\
...
In fact, "const char*" is enough to suppress the warnings. Using "const char* foo=\"blarblar\"" is a good habit because it can avoid the following bugs:
char *s = "whatever";
...
strcpy(s, "Hello, this is a string longer than the initial one.");
The above code can successfully generate an executable, but it will encounter segmentation fault while executing. "const char*" means we should not change the variable in other place, which is important to suppress bugs.

Another problem, if I change the "experim.h" as I wished, new warnings appeared when the compiler parsing the following code:
status = db_create_record(hDB, 0, set_str, strcomb(expcvadc_settings_str));
Warning:
cvadcfe.c: In function ‘frontend_init’:
cvadcfe.c:144: warning: passing argument 1 of ‘strcomb’ from incompatible pointer type
  665   20 Oct 2009 Peter SimpsonForumMidas in linux
Hi,
I'm new to both Linux and Midas and having trouble installing the programme - 
the install file suggeats that I should have a directory:

midas/unix

but this doesn't appear.

Also, when running the "make" for the library (step 3 of the installation), I 
don't see the directory "zlib.a", but there is a "libz.a" and I note the 
original .tar file has no libz.a file in it. Is this a typo on the 
installation?
The terminal window at this point displays:

undefined reference to `errno'
make: ***[example] Error 1

Further help will no doubt be required as I've used windows throughout my 
research and now looking to learn how to use linux. Any help greatly 
appreciated. Thanks!
