typedef uint32_t(* rte_power_freqs_t) (unsigned int lcore_id, uint32_t *freqs, uint32_t num) |
Get the available frequencies of a specific lcore. Function pointer definition. Review each environments specific documentation for usage.
lcore_id | lcore id. |
freqs | The buffer array to save the frequencies. |
num | The number of frequencies to get. |
Definition at line 115 of file rte_power.h.
typedef uint32_t(* rte_power_get_freq_t) (unsigned int lcore_id) |
Return the current index of available frequencies of a specific lcore. Function pointer definition. Review each environments specific documentation for usage.
lcore_id | lcore id. |
Definition at line 131 of file rte_power.h.
typedef int(* rte_power_set_freq_t) (unsigned int lcore_id, uint32_t index) |
Set the new frequency for a specific lcore by indicating the index of available frequencies. Function pointer definition. Review each environments specific documentation for usage.
lcore_id | lcore id. |
index | The index of available frequencies. |
Definition at line 151 of file rte_power.h.
typedef int(* rte_power_freq_change_t) (unsigned int lcore_id) |
Function pointer definition for generic frequency change functions. Review each environments specific documentation for usage.
lcore_id | lcore id. |
Definition at line 167 of file rte_power.h.
typedef int(* rte_power_get_capabilities_t) (unsigned int lcore_id, struct rte_power_core_capabilities *caps) |
Returns power capabilities for a specific lcore. Function pointer definition. Review each environments specific documentation for usage.
lcore_id | lcore id. |
caps | pointer to rte_power_core_capabilities object. |

__rte_experimental int rte_power_check_env_supported | ( | enum power_management_env | env | ) |
Check if a specific power management environment type is supported on a currently running system.
env | The environment type to check support for. |
int rte_power_set_env | ( | enum power_management_env | env | ) |
Set the default power management implementation. If this is not called prior to rte_power_init(), then auto-detect of the environment will take place. It is thread safe. New env can be set only in uninitialized state (thus rte_power_unset_env must be called if different env was already set).
env | env. The environment in which to initialise Power Management for. |
void rte_power_unset_env | ( | void | ) |
Unset the global environment configuration. This can only be called after all threads have completed.
enum power_management_env rte_power_get_env | ( | void | ) |
Get the default power management implementation.
int rte_power_init | ( | unsigned int | lcore_id | ) |
Initialize power management for a specific lcore. If rte_power_set_env() has not been called then an auto-detect of the environment will start and initialise the corresponding resources.
lcore_id | lcore id. |
int rte_power_exit | ( | unsigned int | lcore_id | ) |
Exit power management on a specific lcore. This will call the environment dependent exit function.
lcore_id | lcore id. |
