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@winehq.org ReportedBy: M8R-45axwd@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?
