From 77daf56af9591a9c07c989b51b7511c07d8f3e47 Mon Sep 17 00:00:00 2001 From: wpaul Date: Tue, 10 Aug 1999 17:15:20 +0000 Subject: Convert the VIA Rhine driver to newbus and set it up to be compiled as a module. Also modified the code to work on FreeBSD/alpha and added device vr0 to the alpha GENERIC config. While I was in the neighborhood, I noticed that I was still using #define NFPX 1 in all of the Makefiles that I'd copied from the fxp module. I don't really use #define Nfoo X so it didn't matter, but I decided to customize this correctly anyway. --- sys/pci/if_vr.c | 279 +++++++++++++++++++++++++++++++++-------------------- sys/pci/if_vrreg.h | 6 +- 2 files changed, 182 insertions(+), 103 deletions(-) (limited to 'sys/pci') diff --git a/sys/pci/if_vr.c b/sys/pci/if_vr.c index dfa293b..6e78de4 100644 --- a/sys/pci/if_vr.c +++ b/sys/pci/if_vr.c @@ -29,7 +29,7 @@ * ARISING IN ANY WAY OUT OF THE USE OF THIS SOFTWARE, EVEN IF ADVISED OF * THE POSSIBILITY OF SUCH DAMAGE. * - * $Id: if_vr.c,v 1.12 1999/07/02 04:17:15 peter Exp $ + * $Id: if_vr.c,v 1.13 1999/07/06 19:23:31 des Exp $ */ /* @@ -85,6 +85,9 @@ #include #include #include +#include +#include +#include #include #include @@ -97,7 +100,7 @@ #ifndef lint static const char rcsid[] = - "$Id: if_vr.c,v 1.12 1999/07/02 04:17:15 peter Exp $"; + "$Id: if_vr.c,v 1.13 1999/07/06 19:23:31 des Exp $"; #endif /* @@ -131,12 +134,13 @@ static struct vr_type vr_phys[] = { { 0, 0, "" } }; -static unsigned long vr_count = 0; -static const char *vr_probe __P((pcici_t, pcidi_t)); -static void vr_attach __P((pcici_t, int)); +static int vr_probe __P((device_t)); +static int vr_attach __P((device_t)); +static int vr_detach __P((device_t)); static int vr_newbuf __P((struct vr_softc *, - struct vr_chain_onefrag *)); + struct vr_chain_onefrag *, + struct mbuf *)); static int vr_encap __P((struct vr_softc *, struct vr_chain *, struct mbuf * )); @@ -150,7 +154,7 @@ static int vr_ioctl __P((struct ifnet *, u_long, caddr_t)); static void vr_init __P((void *)); static void vr_stop __P((struct vr_softc *)); static void vr_watchdog __P((struct ifnet *)); -static void vr_shutdown __P((int, void *)); +static void vr_shutdown __P((device_t)); static int vr_ifmedia_upd __P((struct ifnet *)); static void vr_ifmedia_sts __P((struct ifnet *, struct ifmediareq *)); @@ -172,6 +176,33 @@ static void vr_reset __P((struct vr_softc *)); static int vr_list_rx_init __P((struct vr_softc *)); static int vr_list_tx_init __P((struct vr_softc *)); +#ifdef VR_USEIOSPACE +#define VR_RES SYS_RES_IOPORT +#define VR_RID VR_PCI_LOIO +#else +#define VR_RES SYS_RES_MEMORY +#define VR_RID VR_PCI_LOMEM +#endif + +static device_method_t vr_methods[] = { + /* Device interface */ + DEVMETHOD(device_probe, vr_probe), + DEVMETHOD(device_attach, vr_attach), + DEVMETHOD(device_detach, vr_detach), + DEVMETHOD(device_shutdown, vr_shutdown), + { 0, 0 } +}; + +static driver_t vr_driver = { + "vr", + vr_methods, + sizeof(struct vr_softc) +}; + +static devclass_t vr_devclass; + +DRIVER_MODULE(vr, pci, vr_driver, vr_devclass, 0, 0); + #define VR_SETBIT(sc, reg, x) \ CSR_WRITE_1(sc, reg, \ CSR_READ_1(sc, reg) | x) @@ -869,39 +900,33 @@ static void vr_reset(sc) * Probe for a VIA Rhine chip.
