hi..
jeff commited his cpu set and I tried to map that to linuxulator
version of linux_sched_getaffinity(), the current (untested) code
looks like this:
/*
* Get affinity of a process
*/
int
linux_sched_getaffinity(struct thread *td,
struct linux_sched_getaffinity_args *args)
{
int error;
struct cpuset_getaffinity_args cga;
if (args->len < sizeof(cpumask_t))
return (EINVAL);
cga.level = CPU_LEVEL_WHICH;
cga.which = CPU_WHICH_PID;
cga.id = args->pid;
cga.cpusetsize = sizeof(cpumask_t) * NBBY;
cga.mask = (long *) args->user_mask_ptr;
if ((error = cpuset_getaffinity(td, &cga)) == 0)
td->td_retval[0] = sizeof(cpumask_t);
return (error);
}
can someone comment on this? thnx
roman
