[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH v1 12/19] xen/sysctl: wrap around XEN_SYSCTL_cpupool_op
Function cpupool_do_sysctl is designed for doing cpupool related sysctl operations, and shall be wrapped. The following static functions are only called by cpupool_do_sysctl(), then shall be wrapped too: - cpupool_get_next_by_id - cpupool_destroy - cpupool_unassign_cpu_helper - cpupool_unassign_cpu Signed-off-by: Penny Zheng <Penny.Zheng@xxxxxxx> --- xen/common/sched/cpupool.c | 9 +++++++++ xen/include/xen/sched.h | 7 +++++++ 2 files changed, 16 insertions(+) diff --git a/xen/common/sched/cpupool.c b/xen/common/sched/cpupool.c index 3d02c7b706..0efd8a4591 100644 --- a/xen/common/sched/cpupool.c +++ b/xen/common/sched/cpupool.c @@ -241,10 +241,12 @@ struct cpupool *cpupool_get_by_id(unsigned int poolid) return __cpupool_get_by_id(poolid, true); } +#ifdef CONFIG_SYSCTL static struct cpupool *cpupool_get_next_by_id(unsigned int poolid) { return __cpupool_get_by_id(poolid, false); } +#endif /* CONFIG_SYSCTL */ void cpupool_put(struct cpupool *pool) { @@ -352,6 +354,8 @@ static struct cpupool *cpupool_create(unsigned int poolid, return ERR_PTR(ret); } + +#ifdef CONFIG_SYSCTL /* * destroys the given cpupool * returns 0 on success, 1 else @@ -379,6 +383,7 @@ static int cpupool_destroy(struct cpupool *c) debugtrace_printk("cpupool_destroy(pool=%u)\n", c->cpupool_id); return 0; } +#endif /* CONFIG_SYSCTL */ /* * Move domain to another cpupool @@ -568,6 +573,7 @@ static int cpupool_unassign_cpu_start(struct cpupool *c, unsigned int cpu) return ret; } +#ifdef CONFIG_SYSCTL static long cf_check cpupool_unassign_cpu_helper(void *info) { struct cpupool *c = info; @@ -633,6 +639,7 @@ static int cpupool_unassign_cpu(struct cpupool *c, unsigned int cpu) } return continue_hypercall_on_cpu(work_cpu, cpupool_unassign_cpu_helper, c); } +#endif /* CONFIG_SYSCTL */ /* * add a new domain to a cpupool @@ -810,6 +817,7 @@ static void cpupool_cpu_remove_forced(unsigned int cpu) rcu_read_unlock(&sched_res_rculock); } +#ifdef CONFIG_SYSCTL /* * do cpupool related sysctl operations */ @@ -975,6 +983,7 @@ int cpupool_do_sysctl(struct xen_sysctl_cpupool_op *op) return ret; } +#endif /* CONFIG_SYSCTL */ unsigned int cpupool_get_id(const struct domain *d) { diff --git a/xen/include/xen/sched.h b/xen/include/xen/sched.h index 9bdeb85aa4..ea81832c50 100644 --- a/xen/include/xen/sched.h +++ b/xen/include/xen/sched.h @@ -1259,7 +1259,14 @@ static always_inline bool is_cpufreq_controller(const struct domain *d) } int cpupool_move_domain(struct domain *d, struct cpupool *c); +#ifdef CONFIG_SYSCTL int cpupool_do_sysctl(struct xen_sysctl_cpupool_op *op); +#else +static inline int cpupool_do_sysctl(struct xen_sysctl_cpupool_op *op) +{ + return -EOPNOTSUPP; +} +#endif unsigned int cpupool_get_id(const struct domain *d); const cpumask_t *cpupool_valid_cpus(const struct cpupool *pool); -- 2.34.1
