Question about SVC 109

[Lindy Mayfield]

Can someone please tell me if I have gotten this right? (:

SVC's are numbered from 0 to 255.

>From 0 to 199 are reserved for IBM use.

SVC 109 is basically an SVC that can call an SVC from 0 to 255, and again IBM 
has reserved 0 - 199 for their own use.  This in essence extends the range of 
SVC's from 256 to 256*2.

SVC's called by SVS 109 can only be type-4 SVC's.

Why not type-3?  Nowdays, I cannot see any differences between type-3 and 
type-4.  Am I missing something?

thanks so much.
Lindy

Sorry I'm late to the game, folks!

File CBT531 contains a Rexx, SVCSRCH, that displays the first 160 bytes in
hex for any/all SVCs. When it encounters an ESR SVC in also displays the table.

SVC 109 is a distinct type-4 SVC in its own right, and it is a middle-man.
By the early 1970s when it was created, IBM was running out of the 128 SVC
numbers that we'd claimed for our own.  SVC 109 was part of the answer.  It
steals one of the GPRs that other type-4 SVCs might want to use as part of
their API and uses its contents as a function code.  The function code
determines which module, in turn, receives control from the middle-man.
The functional module(s) deliver the function(s).  SVC 109 has none of its
own.

Re: Question about SVC 109

[Lindy Mayfield]

Hello Rob,

I see what you are saying, but one thing that was a bit confusing (after some 
research) was the doc here that says "ESR (type 4) SVC - is type-2".
http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA2V260/1.4.3.112?SHELF=IEA2BK61&DT=20050713173259

But, I also from that see that I was a bit wrong in what I said:  SVC 109 can 
route to a type-3 or type-4 SVC routine.

So I guess my question here is really this:  If I want to write an SVC routine 
and install it as an ESR SVC (SVC 109) and call it that way, then what type 
should my user-written SVC be?  Type-3 or Type-4, or does it matter?

The doc above says specifically:
ESR (type 4) SVC - is type 2

But I didn't quite understand that.  Seems SVC 109 is a type-2 that only calls 
type-4 SVC's, but that doesn't quit jive for me (yet).  That was my question.

As I recall, TYPE 3 are single page SVCs, while TYPE 4 may be larger
than 4096 in size.

But for all intents and purposes, they are the same now. But as a
purist, and to prevent some weird and hard to diagnose error, I honor
the difference.

And just to confuse things futher, I cannot see any significant
difference between a type 2, type 3, or type 4 SVC. In the past, a type
3 SVC was dynamically loaded from SVCLIB into a transient area (I think
that's what it was called). This area was fixed in size, so a type 3
could not be larger than that (4K?). If you had an SVC which needed to
be larger, you created a type 4 SVC. The only difference between a type
3 and a type 4 was that a type 4 could do an XCTL to another "segment"
of itself (an independant module in SVCLIB). This was a sort of dynamic
overlay structure. Today, a type 3 can be as large as you need, so I see
absolute NO need for a type 4 any more. In fact, the type 3 should be
more efficient because it would not do the XCTL. Both are LPA resident,
so that is the same. A type 2 SVC is NUCLEUS resident (but can now be
loaded as an independant module in SYS1.NUCLEUS). IIRC, the nucleus is
still non-pageable (true?). In the past, I remember some SVCs being type
2 so that they could modify themselves (like do a GETMAIN on the very
first call, and save the address in the SVC's "data" area). As far as I
can see, in today's z/OS environment, everything could be architected as
a type 1, 3, or 6 SVC with no real impact on functionality. If I'm
blowing smoke, please educate me on the advantages of a type 2 (other
than no paging, I guess) or a type 4.

and it would be possible to go further.  PC-based schemes could replace all 
SVCs; and they could do so to advantage, but not to great enough advantage 
to justify the use of the resources that would be required to accomplish 
such a conversion.  (The use of an SVC ab initio in a new facility would 
indeed raise questions about the technical judgment of its designer, but to 
say this is not to say that there is any rationale for getting rid of most 
of those we have.)


What was important about SVC 109 was its use a router in the fashion that is 
very well described in Bob Wright's post.

Re: Question about SVC 109

[Lindy Mayfield]

Really?  So I got the SVC 109 half wrong then?  Is this correct?

SVC routines go from 0 to 255 with 200 to 255 reserved for users.

SVC 109 routines 0 through 199 are reserved for IBM use.  Otherwise I can go 
from ... 200 to 9?  

Why did you say IGXyyxxx? What is the reason for yy vs ?  I have to admit 
that my references here are mostly Cannatello's book plus IBM docs that I can 
find.

Re: Question about SVC 109

SVC 109 by itself might be said to consist of just a table which identifies
the extended SVC routines. That table is treated the same as a type 2 SVC,
being in the nucleus, and having its name formed by the standard nucleus
SVC convention of "IGC" concatenated to the decimal SVC number.

The extended SVC routine that a user provides are expected to be in LPA
(which is part of the definition of a type 3 / type 4 SVC).

Hi Peter,

Thanks very much for your answers.  Perhaps I should be more specific about my 
questions:

What is the range of numbers for an SVC routine that is invoked by SVC 109 that 
are reserved for IBM use?

What is the entire range that can be user-written SVC routines that are invoked 
by SVC 109?

Can a user-written SVC routine invoked by SVC 109 be a type-3 or type-4, or is 
it only type-4?  

Surely, if there is a link to the docs that you can point me to where I can 
read this, I'm happy to do the work myself. (-: I just didn't find it (yet).

You really need a tool that will display the SVC table(s), such as 
SHOWZOS or CA-EXAMINE. I recommend SHOWZOS. You also really should have 
a mechanism to display the first few bytes of the modules that are 
identified; IPCS can do it if you're looking at the active system. And 
you need enough control over your security system so that any updates 
and/or additions to you operating system can be very closely monitored. 
The IMON tool from Greg Price is also a very good way to check this out. 
As Mr. Goldis points out, it really needs to be a real-time examination, 
as opposed to a simple PARMLIB check.

Peter, if that's the case, why are so many vendors using slots in the 
0-199 range for their own "goodies"? or are they using slots for 
obsolete products that are no longer supplied or supported by IBM?


When are you folks going to allow (E)SPIE to process MONITOR CALL

>Nowdays, I cannot see any differences between type-3 and type-4.

Back in OS/360 days the difference was only documentation, not
functional. A type 3, or even a type 2, SVC could do an XCTL and it
would work just fine.

What are the most important three factors in real estate? The
difference is location. Type 2 is in the nucleus, and thus external
symbols in the nucleus will be resolved at IPL time. Types 3 and for
are in the LPA list and external references can only be resolved at
link/bind time.

Yes. Likewise type 4.

1 kiB in OS/360, 2 in OS/VS1.

That was a documentation difference; the Supervisor actually supported
XCTL from types 2, 3 and 4.

>IIRC, the nucleus is still non-pageable (true?).

Aren't there both pageable and nonpageable csects in the nucleus these
days?

No. You need type 2 to resolve references to other nucleus symbols.

>If I'm blowing smoke, please educate me on the advantages of a type 2
>(other than no paging, I guess) or a type 4.

Over what? The advantage of type 2 over 3 or 4 is as above. The
advantage over type 1 is that you can issue other SVCs.

I don't know about most, but OPEN, CLOSE and EOV were restructured as
part of the original AOS2 (OS/VS2) development; the WTG table uses
addresses rather than TTRs.

Those are ESR routines rather than SVC routines.

>You call "SVC 109" with yyxxx in R15.

No, just yy.

No, but load if you load F'15' into R15 and issue a SVC 109 it will
link to IGX15109.

No; the ESR number goes from 0 to 99.

>Why did you say IGXyyxxx? 

The xxx is the SVC number, in this case, 109.

SVC 109 does not invoke user-specified SVC routines, it invokes ESR
routines.

>Can a user-written SVC routine invoked by SVC 109 be a type-3 or
>type-4, or is it only type-4? 

SVC 109 cannot invoke a user-written SVC routine, so there is no SVC
type to worry about.

My appologies; I recalled the naming convention as having been
IGXxx109 for SVC 109 with R15=xx, but in fact it seems to be IGX00xxx.
