pciconfig_read
PCICONFIG_READ(2) Linux Programmer's Manual PCICONFIG_READ(2)NAME
pciconfig_read, pciconfig_write, pciconfig_iobase - pci device information handling
SYNOPSIS
#include <pci.h>
int pciconfig_read(unsigned long bus, unsigned long dfn,
unsigned long off, unsigned long len, void *buf);
int pciconfig_write(unsigned long bus, unsigned long dfn,
unsigned long off, unsigned long len, void *buf);
int pciconfig_iobase(long which, unsigned long bus,
unsigned long devfn);
DESCRIPTION
Most of the interaction with PCI devices is already handled by the kernel PCI layer, and thus these calls should not normally need to be
accessed from user space.
pciconfig_read()
Reads to buf from device dev at offset off value.
pciconfig_write()
Writes from buf to device dev at offset off value.
pciconfig_iobase()
You pass it a bus/devfn pair and get a physical address for either the memory offset (for things like prep, this is 0xc0000000), the
IO base for PIO cycles, or the ISA holes if any.
RETURN VALUE
pciconfig_read()
On success zero is returned. On error, -1 is returned and errno is set appropriately.
pciconfig_write()
On success zero is returned. On error, -1 is returned and errno is set appropriately.
pciconfig_iobase()
Returns information on locations of various I/O regions in physical memory according to the which value. Values for which are:
IOBASE_BRIDGE_NUMBER, IOBASE_MEMORY, IOBASE_IO, IOBASE_ISA_IO, IOBASE_ISA_MEM.
ERRORS
EINVAL len value is invalid. This does not apply to pciconfig_iobase().
EIO I/O error.
ENODEV For pciconfig_iobase(), "hose" value is NULL. For the other calls, could not find a slot.
ENOSYS The system has not implemented these calls (CONFIG_PCI not defined).
EOPNOTSUPP
This return value is only valid for pciconfig_iobase(). It is returned if the value for which is invalid.
EPERM User does not have the CAP_SYS_ADMIN capability. This does not apply to pciconfig_iobase().
CONFORMING TO
These calls are Linux-specific, available since Linux 2.0.26/2.1.11.
