Identify.c
NOTE: several routines that use Apple's NameRegistryLib appear at the end of this file.
If you don't have that file, then un-comment the first line above.
Each routine returns an informative C string. Here are samples. (I suggest you
use BreakLines() to printf the longer ones.)
IdentifyCompiler:
"Compiled by Metrowerks CodeWarrior C 7.00 for PowerPC, 4B int and 8B double."
IdentifyOwner:
"Denis Pelli"
IdentifyModel:
"PowerBook 170"
IdentifyMachine:
"Denis Pelli's PowerBook 170, 68030, 68882, System 7.1.0."
"Mal's PowerMac 8500/120, ppc604, L2 cache, System 7.5.2."
IdentifyVideo(device):
"PowerBook 170 \"Macintosh D Built-In Video\" (.Display_Video_Apple_TIM) in slot 0"
"PowerMac 8500/120 \"Built-in video\" (.Display_Video_Apple_Control)"
The computer model appears only if the slot==0, which indicates built-in video.
Quotes embrace the card name, and parentheses embrace the driver name.
The driver's version number appears only if it's non-zero.
HISTORY:
1/29/92 dgp wrote IdentifyCompiler.
2/25/92 dgp wrote IdentifyMachine.
8/26/92 dgp get owner and model name from the System file
2/20/93 dgp added ROM version
2/27/93 dgp merged IdentifyCompiler.c and IdentifyMachine.c into the new Identify.c,
and added IdentifyVideo.
4/25/93 dgp IdentifyMachine reports 24/32-bit addressing.
12/14/93 dgp If THINK C compiler version is "5" I report "5 or 6.0" since Symantec
forgot to increment the version number when they released 6.0. They
fixed this in version 6.01.
3/2/94 dgp Extracted IdentifyOwner from within IdentifyMachine
7/28/94 dgp added support for Metrowerks CodeWarrior C compiler and PowerPC.
Eliminated use of "#s" printf format, since it's not supported by
Metrowerks CodeWarrior C.
9/5/94 dgp removed assumption in printf's that int==short.
9/6/94 dgp Enhanced IdentifyCompiler to specify the size of int.
9/6/94 dgp Disable cache checks on PowerPC, because those traps are undefined.
10/5/94 dgp Removed all floating point code from IdentifyCompiler().
11/5/94 dgp Suppressed ROM info in Identify.
11/9/94 dgp added IdentifyApplication().
1/15/95 dgp added test for version 5 of CodeWarrior
5/24/95 dgp added test for version 6 of CodeWarrior
6/14/95 dgp added GetCPUSpeed() to IdentifyMachine() and abbreviated the report,
omitting a lot of boring stuff.
6/27/95 dgp adjusted UNIVERSAL_HEADERS conditional for GMT struct, to use old
structure for version 1 universal headers.
7/20/95 dgp once again, made compatible with pre-universal headers
8/10/95 dgp updated IdentifyCompiler() for Symantec C.
9/26/95 dgp updated IdentifyCompiler() for CW7.
10/5/95 dgp minor editing of IdentifyVideo().
10/14/95 dgp added support for PCI Macs, using the NameRegistry. Since System 7.5 fails to
adequately name most Macs, I've reverted to using a built-in table of names in
IdentifyModel. IdentifyMachine now also prints the Gestalt machine number to
resolve any residual ambiguities.
IdentifyModel, IdentifyVideo, and IdentifyMachine now give complete information on all
Macs, provided that when running on PCI Macs they are compiled as PPC code. This
limitation is due to the (easy) way that I implemented the calls to Apple's
NameRegistryLib. The NameRegistry-related routines appear in a long self-contained
section at the end of this file.
10/24/95 dgp added pclk and bclk Gestalt calls, based on gestalt-selectors-31.
12/4/95 dgp As requested by David Brainard, changed "char *machineName[]" to
"char machineName[][32]" so that it would compile as a code resource.
3/7/96 dgp report system version number in standard format, e.g. "7.5.3".
3/18/96 dgp IdentifyModel() now always reports actual clock speed if known.
5/14/96 dgp Added mach codes for new Macs from GestaltSelectorList 3.3.5.
5/28/96 dgp Added conditional UNIVERSAL_INTERFACES_VERSION>=0x0212

Using Apple's NameRegistry
void GetVideoProperties(GDHandle device,char *slotName,char *cardName,char *cardModel);
void GetCPUProperties(char *cpuName,long *cpuHz,Boolean *hasL2Cache);
Two routines that use the new Name Registry (available only on PCI PowerMacs) to
determine the cpu clock rate, presence of L2 cache, and the name of the PCI video
card. The routines return zeroes if the Name Registry is not available (i.e. on
non-PCI Macs), or if compiled as 68k code.
WARNING: to effectively use Apple's NameRegistry in your project you MUST have Apple's
NameRegistryLib, which contains the glue code to access the MacOS. NameRegistryLib
is in the VideoToolbox Libs folder; add it to your project and use the pop-up
menu to select "import 'weak'".) As of 1/96, Apple has
distributed NameRegistry.h and NameRegistryLib only as part of the Apple
Developer Mailing and the SDK Subscription (either costs $250/year from APDA). These
two files are not included with Metrowerks CodeWarrior 8. You don't need
NameRegistry.h, because Identify.c includes the needed definitions, but you do need
NameRegistryLib, which is in the VideoToolbox Libs folder. Alternatively,
you may set the flag NO_NAME_REGISTRY_LIB to true, which will disable the rest of
this file, but allows you to link and run your programs.
Once compiled and linked with the NameRegistryLib glue, this code will run on any
PCI PowerMac. A temporary #if section takes care of the missing header file, so
you'll be able to compile, but I don't think you'll be able to link this unless
you have NameRegistryLib. I confess to being somewhat unsure on the last point
since there are suggestions in the original source files that NameRegistryLib
could be installed in the System:Extensions folder of the target machine instead
of being linked into the application itself. That is apparently what the call
below to Code Fragment Manager is for. However, I don't really understand this
arcane stuff (i.e. "weak linking"), and it didn't seem worth learning for the
routines in this file. Metrowerks has a "weak-linking" option, but limited
experimentation suggests that you have to have the library in order to weak-link
to it, which is no help at all for someone who doesn't have the library.
HISTORY:
10/13/95 dgp wrote GetVideoProperties() and GetCPUProperties(), based on general
advice from Apple (below) and
the PCISlotsUtils.cp source file for Apple's "PCI Slot Peek" demo,
in the PCI developer's kit included on the September '95 Developer's CD.
Hi Denis
Thank you for your link (ID# 151426) concerning how to detect a L2 cache and
get the processor speed.
Let's look at the cache first. Before the introduction of the PCI Power
Macintosh computers there was no API to detect the presents of this cache. On
a PCI Macintosh there is the Name Registry. This registry contains this
information in the form of a property. The property name is "name" and if
there is a L2 cache the property value is "l2-cache". Look at the Developer CD
for Sept 95. In the What's New folder there is the PCI DDK. There is a
program called Display Name Registry that will show what I have just explained.
Of course it must run on a PCI machine. There is also a document called
"Designing PCI Cards&Drivers...." that shows examples of using the Name
Registry to search for system resources.
Now the CPU speed. Like the last case, before PCI Macs there was no direct
call that could be made to determine CPU speed. There are Gestalt calls for
CPU type if that's any help. However, there are CPU accelerator cards so that
would present a problem. The two calls you mentioned (GetCPUSPeed &
MaximumProcessSpeed) are both for portable Macs that use the Power Manager.
The traps for these calls are not implemented on other Macs. At least not the
9500 that I tried. However, PCI Macs and the Name Registry contain this
information also. Again go to Display Name Registry and look at the
Devices:device-tree;PowerPC,604 property. Expand it and there is an additional
sub property called "clock-frequency". My 9500 show 132000000.
So you have what you want but starting with PCI Macs.

You can use the Name Registry to determine if a PCI bus exists. To do this you

entry is found that has that known property/value (noErr and done = "False"),
there is a PCI bus.
