uint64_t rte_get_tsc_hz | ( | void | ) |
Get the measured frequency of the RDTSC counter
|
inlinestatic |
Return the number of TSC cycles since boot
|
inlinestatic |
Get the number of cycles since boot from the default timer.
Definition at line 93 of file rte_cycles.h.
|
inlinestatic |
Get the number of cycles in one second for the default timer.
Definition at line 115 of file rte_cycles.h.
|
inlinestatic |
Wait at least ms milliseconds.
ms | The number of milliseconds to wait. |
Definition at line 147 of file rte_cycles.h.
void rte_delay_us_block | ( | unsigned int | us | ) |
Blocking delay function.
us | Number of microseconds to wait. |
void rte_delay_us_sleep | ( | unsigned int | us | ) |
Delay function that uses system sleep. Does not block the CPU core.
us | Number of microseconds to wait. |
void rte_delay_us_callback_register | ( | void(*)(unsigned int) | userfunc | ) |
Replace rte_delay_us with user defined function.
userfunc | User function which replaces rte_delay_us. rte_delay_us_block restores builtin block delay function. |
|
extern |
Wait at least us microseconds. This function can be replaced with user-defined function.
us | The number of microseconds to wait. |
