Problem Description: 

4159925: "UEx000 167Mhz512kb CPU - passed POST/SunVTS, but failed 
	compress/uncompress test" This patch augments the existing 
	SunVTS test suite with cpudatatest in order to detect CPU's 
	which may pass other tests and yet fail a 
	compress/uncompress sequence.


Patch Installation Instructions: 
-------------------------------- 
Refer to the Install.info file for instructions on using the
generic 'installpatch' and 'backoutpatch' scripts provided with
each patch.  Any other special or non-generic installation
instructions should be described below as special instructions.


Special Install Instructions: 
----------------------------- 
None.


Special Notes
-------------
1) Command line usage requires the user to specify the command line
   option cpuid=N rather than dev=cpu-unitN. Where N may range from 0 to 31. 
   Refer to /opt/SUNWvts/bin/cpudatatest.txt for more information after
   the patch is installed.

2) The user should not attempt to change the Processor Affinity for
   any instance of cpudatatest because the test is designed to run with
   the defaults assigned during probing. 

3) A message similar to:

	"ERROR: number of instances exceeds max.(1) allowable by cpudatatest!"

   may appear when attempting to apply changes to test execution options
   such as enable/disable core or verbose. The workaround is to reduce the
   number of instances in the submenu to 1 before clicking the apply button.
   The details may vary depending upon which user interface is being used.

4) Similar problems (as in 3) were noted with the CDE user interface when 
   attempting to enable tracing. Multiple instances on the submenu conflicted 
   with cpudatatest's limit of one instance per processor. The workaround
   is to select only the first instance.

5) "cpudatatest" representation on the status panel of SunVTS OpenLook screen
   is too long so one or two characters may overlap with "Passes" labels.

6) During testing it was noted that under some circumstances attempting to
   select Test_Parameter or Test_Execution submenu for cpudatatest 
   from the tty user interface would cause a Segmentation Violation.
   See BugId 4208149 for details.  The workaround is to use one of the
   graphical user interfaces. An alternate workaround is to not select 
   either of the above submenus from the tty user interface.
