This driver is written so that different cards - * can be automatically detected at run-time. - */ - -/* -Mode of operation: - -We run the 82586 in a standard Ethernet mode. We keep NFRAMES received -frame descriptors around for the receiver to use, and NRXBUFS associated -receive buffer descriptors, both in a circular list. Whenever a frame is -received, we rotate both lists as necessary. (The 586 treats both lists -as a simple queue.) We also keep a transmit command around so that packets -can be sent off quickly. - -We configure the adapter in AL-LOC = 1 mode, which means that the -Ethernet/802.3 MAC header is placed at the beginning of the receive buffer -rather than being split off into various fields in the RFD. This also -means that we must include this header in the transmit buffer as well. - -By convention, all transmit commands, and only transmit commands, shall -have the I (IE_CMD_INTR) bit set in the command. This way, when an -interrupt arrives at ieintr(), it is immediately possible to tell -what precisely caused it. ANY OTHER command-sending routines should -run at splimp(), and should post an acknowledgement to every interrupt -they generate. - -The 82586 has a 24-bit address space internally, and the adaptor's memory -is located at the top of this region. However, the value we are given in -configuration is normally the *bottom* of the adaptor RAM. So, we must go -through a few gyrations to come up with a kernel virtual address which -represents the actual beginning of the 586 address space. First, we -autosize the RAM by running through several possible sizes and trying to -initialize the adapter under the assumption that the selected size is -correct. Then, knowing the correct RAM size, we set up our pointers in -ie_softc[unit]. `iomem' represents the computed base of the 586 address -space. `iomembot' represents the actual configured base of adapter RAM. -Finally, `iosize' represents the calculated size of 586 RAM. Then, when -laying out commands, we use the interval [iomembot, iomembot + iosize); to -make 24-pointers, we subtract iomem, and to make 16-pointers, we subtract -iomem and and with 0xffff. - -*/ - -#include "ie.h" -#if NIE > 0 -#include "opt_inet.h" -#include "opt_ipx.h" - -#include <sys/param.h> -#include <sys/systm.h> -#include <sys/eventhandler.h> -#include <sys/kernel.h> -#include <sys/malloc.h> -#include <sys/conf.h> -#include <sys/mbuf.h> -#include <sys/socket.h> -#include <sys/sockio.h> -#include <sys/syslog.h> - -#include <net/ethernet.h> -#include <net/if.h> -#include <net/if_types.h> -#include <net/if_dl.h> - -#include <netinet/in.h> -#include <netinet/if_ether.h> - -#include <machine/clock.h> -#include <machine/md_var.h> - -#include <i386/isa/isa_device.h> -#include <i386/isa/ic/i82586.h> -#include <i386/isa/icu.h> -#include <i386/isa/if_iereg.h> -#include <i386/isa/if_ie507.h> -#include <i386/isa/if_iee16.h> -#include <i386/isa/elink.h> - -#include <net/bpf.h> - -#ifdef DEBUG -#define IED_RINT 0x01 -#define IED_TINT 0x02 -#define IED_RNR 0x04 -#define IED_CNA 0x08 -#define IED_READFRAME 0x10 -static int ie_debug = IED_RNR; - -#endif - -#define IE_BUF_LEN ETHER_MAX_LEN /* length of transmit buffer */ - -/* Forward declaration */ -struct ie_softc; - -static struct mbuf *last_not_for_us; - -static int ieprobe(struct isa_device * dvp); -static int ieattach(struct isa_device * dvp); -static ointhand2_t ieintr; -static int sl_probe(struct isa_device * dvp); -static int el_probe(struct isa_device * dvp); -static int ni_probe(struct isa_device * dvp); -static int ee16_probe(struct isa_device * dvp); - -static int check_ie_present(int unit, caddr_t where, unsigned size); -static void ieinit(void *); -static void ie_stop(int unit); -static int ieioctl(struct ifnet * ifp, u_long command, caddr_t data); -static void iestart(struct ifnet * ifp); - -static void el_reset_586(int unit); -static void el_chan_attn(int unit); - -static void sl_reset_586(int unit); -static void sl_chan_attn(int unit); - -static void ee16_reset_586(int unit); -static void ee16_chan_attn(int unit); -static __inline void ee16_interrupt_enable(struct ie_softc * ie); -static void ee16_eeprom_outbits(struct ie_softc * ie, int edata, int cnt); -static void ee16_eeprom_clock(struct ie_softc * ie, int state); -static u_short ee16_read_eeprom(struct ie_softc * ie, int location); -static int ee16_eeprom_inbits(struct ie_softc * ie); -static void ee16_shutdown(void *sc, int howto); - -static void iereset(int unit); -static void ie_readframe(int unit, struct ie_softc * ie, int bufno); -static void ie_drop_packet_buffer(int unit, struct ie_softc * ie); -static void sl_read_ether(int unit, unsigned char addr[6]); -static void find_ie_mem_size(int unit); -static void chan_attn_timeout(void *rock); -static int command_and_wait(int unit, int command, - void volatile * pcmd, int); -static void run_tdr(int unit, volatile struct ie_tdr_cmd * cmd); -static int ierint(int unit, struct ie_softc * ie); -static int ietint(int unit, struct ie_softc * ie); -static int iernr(int unit, struct ie_softc * ie); -static void start_receiver(int unit); -static __inline int ieget(int, struct ie_softc *, struct mbuf **, - struct ether_header *, int *); -static v_caddr_t setup_rfa(v_caddr_t ptr, struct ie_softc * ie); -static int mc_setup(int, v_caddr_t, volatile struct ie_sys_ctl_block *); -static void ie_mc_reset(int unit); - -#ifdef DEBUG -static void print_rbd(volatile struct ie_recv_buf_desc * rbd); - -static int in_ierint = 0; -static int in_ietint = 0; - -#endif - -/* - * This tells the autoconf code how to set us up. - */ -struct isa_driver iedriver = { - ieprobe, ieattach, "ie", -}; - -enum ie_hardware { - IE_STARLAN10, - IE_EN100, - IE_SLFIBER, - IE_3C507, - IE_NI5210, - IE_EE16, - IE_UNKNOWN -}; - -static const char *ie_hardware_names[] = { - "StarLAN 10", - "EN100", - "StarLAN Fiber", - "3C507", - "NI5210", - "EtherExpress 16", - "Unknown" -}; - -/* -sizeof(iscp) == 1+1+2+4 == 8 -sizeof(scb) == 2+2+2+2+2+2+2+2 == 16 -NFRAMES * sizeof(rfd) == NFRAMES*(2+2+2+2+6+6+2+2) == NFRAMES*24 == 384 -sizeof(xmit_cmd) == 2+2+2+2+6+2 == 18 -sizeof(transmit buffer) == 1512 -sizeof(transmit buffer desc) == 8 ------ -1946 - -NRXBUFS * sizeof(rbd) == NRXBUFS*(2+2+4+2+2) == NRXBUFS*12 -NRXBUFS * IE_RBUF_SIZE == NRXBUFS*256 - -NRXBUFS should be (16384 - 1946) / (256 + 12) == 14438 / 268 == 53 - -With NRXBUFS == 48, this leaves us 1574 bytes for another command or -more buffers.
