             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: wine-bugs at winehq.org
        ReportedBy: M8R-45axwd at mailinator.com
    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?
