cne_umwait()

static __cne_always_inline void cne_umwait ( const uint64_t  timestamp )

static

Execute UMWAIT given the timestamp value.

This function will enter C0.2 state.

For more information about usage of these instructions, please refer to Intel(R) 64 and IA-32 Architectures Software Developer's Manual.

Parameters

timestamp

The number of cycles to wait.

Returns

None.

Definition at line 56 of file cne_isa.h.

cne_tpause()

static __cne_always_inline void cne_tpause ( const uint64_t  timestamp )

static

Execute TPAUSE given the timestamp value.

This function uses TPAUSE instruction and will enter C0.2 state. For more information about usage of this instruction, please refer to Intel(R) 64 and IA-32 Architectures Software Developer's Manual.

Parameters

timestamp

The number of cycles to wait.

Returns

None.

Definition at line 81 of file cne_isa.h.

cne_movdiri()

static __cne_always_inline void cne_movdiri ( volatile void *  addr, uint32_t  value  )

static

MOVDIRI instruction.

Parameters

addr	The address to put the value.
value	The value to move to the given address.

Returns

None.

Definition at line 104 of file cne_isa.h.

cne_movdir64b()

static __cne_always_inline void cne_movdir64b ( volatile void *  dst, const void *  src  )

static

Use movdir64b instruction to move data from source to destination

Parameters

dst	The destination address to put the source data
src	The source address to get the data from.

Returns

None.

Definition at line 121 of file cne_isa.h.

cne_cldemote()

static __cne_always_inline void cne_cldemote ( const volatile void *  p )

static

Demote a cacheline entry

Parameters

p	The address of the cacheline to demote.

Returns

None.
