The Pegasus uses a total of four USB endpoints: the control * endpoint (0), a bulk read endpoint for receiving packets (1), * a bulk write endpoint for sending packets (2) and an interrupt * endpoint for passing RX and TX status (3). Endpoint 0 is used * to read and write the ethernet module's registers. All registers * are 8 bits wide. * * Packet transfer is done in 64 byte chunks. The last chunk in a * transfer is denoted by having a length less that 64 bytes. For * the RX case, the data includes an optional RX status word. */ #ifndef AUEREG_H #define AUEREG_H #define AUE_UR_READREG 0xF0 #define AUE_UR_WRITEREG 0xF1 #define AUE_CONFIG_NO 1 #define AUE_IFACE_IDX 0 /* * Note that while the ADMtek technically has four * endpoints, the control endpoint (endpoint 0) is * regarded as special by the USB code and drivers * don't have direct access to it.

Consequently, our endpoint indexes * don't match those in the ADMtek Pegasus manual: * we consider the RX data endpoint to be index 0 * and work up from there. */ #define AUE_ENDPT_RX 0x0 #define AUE_ENDPT_TX 0x1 #define AUE_ENDPT_INTR 0x2 #define AUE_ENDPT_MAX 0x3 #define AUE_INTR_PKTLEN 0x8 #define AUE_CTL0 0x00 #define AUE_CTL1 0x01 #define AUE_CTL2 0x02 #define AUE_MAR0 0x08 #define AUE_MAR1 0x09 #define AUE_MAR2 0x0A #define AUE_MAR3 0x0B #define AUE_MAR4 0x0C #define AUE_MAR5 0x0D #define AUE_MAR6 0x0E #define AUE_MAR7 0x0F #define AUE_MAR AUE_MAR0 #define AUE_PAR0 0x10 #define AUE_PAR1 0x11 #define AUE_PAR2 0x12 #define AUE_PAR3 0x13 #define AUE_PAR4 0x14 #define AUE_PAR5 0x15 #define AUE_PAR AUE_PAR0 #define AUE_PAUSE0 0x18 #define AUE_PAUSE1 0x19 #define AUE_PAUSE AUE_PAUSE0 #define AUE_RX_FLOWCTL_CNT 0x1A #define AUE_RX_FLOWCTL_FIFO 0x1B #define AUE_REG_1D 0x1D #define AUE_EE_REG 0x20 #define AUE_EE_DATA0 0x21 #define AUE_EE_DATA1 0x22 #define AUE_EE_DATA AUE_EE_DATA0 #define AUE_EE_CTL 0x23 #define AUE_PHY_ADDR 0x25 #define AUE_PHY_DATA0 0x26 #define AUE_PHY_DATA1 0x27 #define AUE_PHY_DATA AUE_PHY_DATA0 #define AUE_PHY_CTL 0x28 #define AUE_USB_STS 0x2A #define AUE_TXSTAT0 0x2B #define AUE_TXSTAT1 0x2C #define AUE_TXSTAT AUE_TXSTAT0 #define AUE_RXSTAT 0x2D #define AUE_PKTLOST0 0x2E #define AUE_PKTLOST1 0x2F #define AUE_PKTLOST AUE_PKTLOST0 #define AUE_REG_7B 0x7B #define AUE_GPIO0 0x7E #define AUE_GPIO1 0x7F #define AUE_REG_81 0x81 #define AUE_CTL0_INCLUDE_RXCRC 0x01 #define AUE_CTL0_ALLMULTI 0x02 #define AUE_CTL0_STOP_BACKOFF 0x04 #define AUE_CTL0_RXSTAT_APPEND 0x08 #define AUE_CTL0_WAKEON_ENB 0x10 #define AUE_CTL0_RXPAUSE_ENB 0x20 #define AUE_CTL0_RX_ENB 0x40 #define AUE_CTL0_TX_ENB 0x80 #define AUE_CTL1_HOMELAN 0x04 #define AUE_CTL1_RESETMAC 0x08 #define AUE_CTL1_SPEEDSEL 0x10 /* 0 = 10mbps, 1 = 100mbps */ #define AUE_CTL1_DUPLEX 0x20 /* 0 = half, 1 = full */ #define AUE_CTL1_DELAYHOME 0x40 #define AUE_CTL2_EP3_CLR 0x01 /* reading EP3 clrs status regs */ #define AUE_CTL2_RX_BADFRAMES 0x02 #define AUE_CTL2_RX_PROMISC 0x04 #define AUE_CTL2_LOOPBACK 0x08 #define AUE_CTL2_EEPROMWR_ENB 0x10 #define AUE_CTL2_EEPROM_LOAD 0x20 #define AUE_EECTL_WRITE 0x01 #define AUE_EECTL_READ 0x02 #define AUE_EECTL_DONE 0x04 #define AUE_PHYCTL_PHYREG 0x1F #define AUE_PHYCTL_WRITE 0x20 #define AUE_PHYCTL_READ 0x40 #define AUE_PHYCTL_DONE 0x80 #define AUE_USBSTS_SUSPEND 0x01 #define AUE_USBSTS_RESUME 0x02 #define AUE_TXSTAT0_JABTIMO 0x04 #define AUE_TXSTAT0_CARLOSS 0x08 #define AUE_TXSTAT0_NOCARRIER 0x10 #define AUE_TXSTAT0_LATECOLL 0x20 #define AUE_TXSTAT0_EXCESSCOLL 0x40 #define AUE_TXSTAT0_UNDERRUN 0x80 #define AUE_TXSTAT1_PKTCNT 0x0F #define AUE_TXSTAT1_FIFO_EMPTY 0x40 #define AUE_TXSTAT1_FIFO_FULL 0x80 #define AUE_RXSTAT_OVERRUN 0x01 #define AUE_RXSTAT_PAUSE 0x02 #define AUE_GPIO_IN0 0x01 #define AUE_GPIO_OUT0 0x02 #define AUE_GPIO_SEL0 0x04 #define AUE_GPIO_IN1 0x08 #define AUE_GPIO_OUT1 0x10 #define AUE_GPIO_SEL1 0x20 struct aue_intrpkt { u_int8_t aue_txstat0; u_int8_t aue_txstat1; u_int8_t aue_rxstat; u_int8_t aue_rxlostpkt0; u_int8_t aue_rxlostpkt1; u_int8_t aue_wakeupstat; u_int8_t aue_rsvd; }; struct aue_rxpkt { u_int16_t aue_pktlen; u_int8_t aue_rxstat; }; #define AUE_RXSTAT_MCAST 0x01 #define AUE_RXSTAT_GIANT 0x02 #define AUE_RXSTAT_RUNT 0x04 #define AUE_RXSTAT_CRCERR 0x08 #define AUE_RXSTAT_DRIBBLE 0x10 #define AUE_RXSTAT_MASK 0x1E #define AUE_INC(x, y) (x) = (x + 1) % y struct aue_softc { #if defined(__FreeBSD__) #define GET_MII(sc) (device_get_softc((sc)->aue_miibus)) #elif defined(__NetBSD__) #define GET_MII(sc) (&(sc)->aue_mii) #elif defined(__OpenBSD__) #define GET_MII(sc) (&(sc)->aue_mii) #endif struct ifnet *aue_ifp; device_t aue_dev; device_t aue_miibus; usbd_device_handle aue_udev; usbd_interface_handle aue_iface; u_int16_t aue_vendor; u_int16_t aue_product; int aue_ed[AUE_ENDPT_MAX]; usbd_pipe_handle aue_ep[AUE_ENDPT_MAX]; int aue_unit; u_int8_t aue_link; int aue_timer; int aue_if_flags; struct ue_cdata aue_cdata; struct callout aue_tick_callout; struct usb_taskqueue aue_taskqueue; struct task aue_task; struct mtx aue_mtx; struct sx aue_sx; u_int16_t aue_flags; char aue_dying; struct timeval aue_rx_notice; struct usb_qdat aue_qdat; int aue_deferedtasks; }; #if 0 /* * Some debug code to make sure we don't take a blocking lock in * interrupt context. */ #include #include #include #define AUE_DUMPSTATE(tag) aue_dumpstate(__func__, tag) static inline void aue_dumpstate(const char *func, const char *tag) { if ((curthread->td_pflags & TDP_NOSLEEPING) || (curthread->td_pflags & TDP_ITHREAD)) { kdb_backtrace(); printf("%s: %s sleep: %sok ithread: %s\n", func, tag, curthread->td_pflags & TDP_NOSLEEPING ?
