Bug ID: 52968
           Summary: CPU BoostTester manages to run only on real cores in
                    Windows, but not with wine
           Product: Wine
           Version: 7.7
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

Hi,
the following tiny porgram is used to test the boost capability of cpus.
It detects real cores and only tests those, not the smt siblings.
On windows it manages to run on the real cores only.
On Linux it runs on the cores 0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30
I am using a 5950x.
The real cores are 0-15. The siblings ar 16-31.
0+16 is a pair, 1+17, 2+18 etc..
So instead of testing the 16 real cores, it is testing only 8 + siblings.
The software is availible here, including source.
I don't know if the software is doing some strange things to detect the real
cores or if the issue is on the wine side.
As the source is just a handful of c++ code, someone with experience might take
a look and judge where the problem is, wine or the program.

Many thx !
