--- Comment #50 from Juan Lang juan_lang@yahoo.com 2009-09-30 19:50:27 --- Actually, I take it back. I wrote a test program that runs under Linux that calls sched_setaffinity and cpuid 1 directly, and it does what I expect: after calling sched_setaffinity, the process's CPU, as reported by cpuid 1, changes. I modifed kernel32 to call cpuid 1 also, and after changing the affinity mask, it does not change CPUs. So this remains a Wine bug, not a kernel bug.
