I/O device memory operations
This file defines the generic API for I/O device memory read/write operations
Definition in file rte_io.h.
|
inlinestatic |
Read a 8-bit value from I/O device memory address addr.
The relaxed version does not have additional I/O memory barrier, useful in accessing the device registers of integrated controllers which implicitly strongly ordered with respect to memory access.
| addr | I/O memory address to read the value from |
|
inlinestatic |
Read a 16-bit value from I/O device memory address addr.
The relaxed version does not have additional I/O memory barrier, useful in accessing the device registers of integrated controllers which implicitly strongly ordered with respect to memory access.
| addr | I/O memory address to read the value from |
|
inlinestatic |
Read a 32-bit value from I/O device memory address addr.
The relaxed version does not have additional I/O memory barrier, useful in accessing the device registers of integrated controllers which implicitly strongly ordered with respect to memory access.
| addr | I/O memory address to read the value from |
|
inlinestatic |
Read a 64-bit value from I/O device memory address addr.
The relaxed version does not have additional I/O memory barrier, useful in accessing the device registers of integrated controllers which implicitly strongly ordered with respect to memory access.
| addr | I/O memory address to read the value from |
|
inlinestatic |
Write a 8-bit value to I/O device memory address addr.
The relaxed version does not have additional I/O memory barrier, useful in accessing the device registers of integrated controllers which implicitly strongly ordered with respect to memory access.

Write a 32-bit value to I/O device memory address addr using write combining memory write protocol. Depending on the platform write combining may not be available and/or may be treated as a hint and the behavior may fallback to a regular store.
