NAME
pci_config_get8, pci_config_get16, pci_config_get32, pci_config_get64,
pci_config_put8, pci_config_put16, pci_config_put32, pci_config_put64,
pci_config_getb, pci_config_getl, pci_config_getll, pci_config_getw,
pci_config_putb, pci_config_putl, pci_config_putll, pci_config_putw -
read or write single datum of various sizes to the PCI Local Bus Con‐
figuration space
SYNOPSIS
#include <sys/ddi.h>
#include <sys/sunddi.h>
uint8_t pci_config_get8(ddi_acc_handle_t handle, off_t offset);
uint16_t pci_config_get16(ddi_acc_handle_t handle, off_t offset);
uint32_t pci_config_get32(ddi_acc_handle_t handle, off_t offset);
uint64_t pci_config_get64(ddi_acc_handle_t handle, off_t offset);
void pci_config_put8(ddi_acc_handle_t handle, off_t offset,
uint8_t value);
void pci_config_put16(ddi_acc_handle_t handle, off_t offset,
uint16_t value);
void pci_config_put32(ddi_acc_handle_t handle, off_t offset,
uint32_t value);
void pci_config_put64(ddi_acc_handle_t handle, off_t offset,
uint64_t value);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). The pci_config_getb(), pci_con‐
fig_getl(), pci_config_getll(), pci_config_getw(), pci_config_putb(),
pci_config_putl(), pci_config_putll(), and pci_config_putw() functions
are obsolete. The pci_config_get8() function replaces pci_con‐
fig_getb(). The pci_config_get32() function replaces pci_config_getl().
The pci_config_get64() function replaces pci_config_getll(). The
pci_config_get16() function replaces pci_config_getw(). The pci_con‐
fig_put8() function replaces pci_config_putb(). The pci_config_put32()
function replaces pci_config_putl(). The pci_config_put64() function
replaces pci_config_putll(). The pci_config_put16() function replaces
pci_config_putw().
PARAMETERS
handle
The data access handle returned from pci_config_setup(9F).
offset
Byte offset from the beginning of the PCI Configuration
space.
value
Output data.
DESCRIPTION
These routines read or write a single datum of various sizes from or to
the PCI Local Bus Configuration space. The pci_config_get8(), pci_con‐
fig_get16(), pci_config_get32(), and pci_config_get64() functions read
8 bits, 16 bits, 32 bits, and 64 bits of data, respectively. The
pci_config_put8(), pci_config_put16(), pci_config_put32(), and pci_con‐
fig_put64() functions write 8 bits, 16 bits, 32 bits, and 64 bits of
data, respectively. The offset argument must be a multiple of the datum
size.
Since th PCI Local Bus Configuration space is represented in little
endian data format, these functions translate the data from or to
native host format to or from little endian format.
pci_config_setup(9F) must be called before invoking these functions.
RETURN VALUES
pci_config_get8(), pci_config_get16(), pci_config_get32(), and pci_con‐
fig_get64() return the value read from the PCI Local Bus Configuration
space.
CONTEXT
These routines can be called from user, kernel, or interrupt context.
