#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). 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_config_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_config_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 the 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_config_get64() return the value read from the PCI Local Bus Configura- tion space. CONTEXT
These routines can be called from user, kernel, or interrupt context. ATTRIBUTES

attributes(5), pci_config_setup(9F), pci_config_teardown(9F) NOTES
These functions are specific to PCI bus device drivers. For drivers using these functions, a single source to support devices with multiple bus versions may not be easy to maintain. The functions described in this manual page previously used symbolic names which specified their data access size; the function names have been changed so they now specify a fixed-width data size.
