CSX_REPGET8(9F)CSX_REPGET8(9F)NAME
csx_RepGet8, csx_RepGet16, csx_RepGet32, csx_RepGet64 - read repeti‐
tively from the device register
SYNOPSIS
#include <sys/pccard.h>
void csx_RepGet8(acc_handle_t handle, uint8_t *hostaddr, uint32_t offset,
uint32_t repcount, uint32_t flags);
void csx_RepGet16(acc_handle_t handle, uint16_t *hostaddr, uint32_t offset,
uint32_t repcount, uint32_t flags);
void csx_RepGet32(acc_handle_t handle, uint32_t *hostaddr, uint32_t offset,
uint32_t repcount, uint32_t flags);
void csx_RepGet64(acc_handle_t handle, uint64_t *hostaddr, uint32_t offset,
uint32_t repcount, uint32_t flags);
INTERFACE LEVEL
Solaris DDI Specific (Solaris DDI)
PARAMETERS
handle
The access handle returned from csx_RequestIO(9F),
csx_RequestWindow(9F), or csx_DupHandle(9F).
hostaddr
Source host address.
offset
The offset in bytes from the base of the mapped resource.
repcount
Number of data accesses to perform.
flags
Device address flags.
DESCRIPTION
These functions generate multiple reads of various sizes from the
mapped memory or device register.
The csx_RepGet8(), csx_RepGet16(), csx_RepGet32(), and csx_RepGet64()
functions generate repcount reads of 8 bits, 16 bits, 32 bits, and 64
bits of data, respectively, from the device address represented by the
handle, handle, at an offset in bytes represented by the offset, off‐
set. The data read is stored consecutively into the buffer pointed to
by the host address pointer, hostaddr.
Data that consists of more than one byte will automatically be trans‐
lated to maintain a consistent view between the host and the device
based on the encoded information in the data access handle. The trans‐
lation may involve byte swapping if the host and the device have incom‐
patible endian characteristics.
When the flags argument is set to CS_DEV_AUTOINCR, these functions
increment the device offset, offset, after each datum read operation.
However, when the flags argument is set to CS_DEV_NO_AUTOINCR, the same
device offset will be used for every datum access. For example, this
flag may be useful when reading from a data register.
CONTEXT
These functions may be called from user, kernel, or interrupt context.
