[Bug 30480] New: Setting CPU affinity doesn't work on Macs

Bug #: 30480
           Summary: Setting CPU affinity doesn't work on Macs
           Product: Wine
           Version: unspecified
          Platform: x86-64
        OS/Version: Mac OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

In the Wine task manager, it is possible to change CPU affinity for an every
process. On Macs, however, this change does nothing, even though the number of
CPUs/cores is correctly detected by taskmgr.exe.

For Mac OS X there are no tools such as taskset or schedtool which could set
affinity on an application basis (hwprefs turns off processor cores
system-wide, so this isn't a practical solution). Thus, implementing the
function to disable or activate CPUs for a given process in Wine, could be
really useful.

PS Is there at least a way to tweak/compile Wine, so that it would
recognize/use only one of the Mac's cores?

AFAIK there's no way to set processor affinity on Mac OS X.

Wouldn't it be possible to add the affinity support (at least optional)
leveraging emulation?
