Instead, it + * programs the Hermes controller directly, using information gleaned + * from the HCF Light code and corresponding documentation. + * + * This driver supports the ISA, PCMCIA and PCI versions of the Lucent + * WaveLan cards (based on the Hermes chipset), as well as the newer + * Prism 2 chipsets with firmware from Intersil and Symbol. + */ + +#include <sys/param.h> +#include <sys/systm.h> +#if __FreeBSD_version >= 500033 +#include <sys/endian.h> +#endif +#include <sys/sockio.h> +#include <sys/mbuf.h> +#include <sys/proc.h> +#include <sys/kernel.h> +#include <sys/socket.h> +#include <sys/module.h> +#include <sys/bus.h> +#include <sys/random.h> +#include <sys/syslog.h> +#include <sys/sysctl.h> + +#include <machine/bus.h> +#include <machine/resource.h> +#include <machine/clock.h> +#include <sys/rman.h> + +#include <net/if.h> +#include <net/if_arp.h> +#include <net/ethernet.h> +#include <net/if_dl.h> +#include <net/if_media.h> +#include <net/if_types.h> +#include <net/if_ieee80211.h> + +#include <netinet/in.h> +#include <netinet/in_systm.h> +#include <netinet/in_var.h> +#include <netinet/ip.h> +#include <netinet/if_ether.h> + +#include <net/bpf.h> + +#include <dev/wi/if_wavelan_ieee.h> +#include <dev/wi/wi_hostap.h> +#include <dev/wi/if_wivar.h> +#include <dev/wi/if_wireg.h> + +#if !defined(lint) +static const char rcsid[] = + "$FreeBSD$";

Here + * is more or less what I know: + * + * - The Hermes controller is firmware driven, and the host interacts + * with the Hermes via a firmware interface, which can change. + * + * - The Hermes is described in a document called: "Hermes Firmware + * WaveLAN/IEEE Station Functions," document #010245, which of course + * Lucent will not release without an NDA. + * + * - Lucent has created a library called HCF (Hardware Control Functions) + * though which it wants developers to interact with the card. The HCF + * is needlessly complex, ill conceived and badly documented. Actually, + * the comments in the HCP code itself aren't bad, but the publically + * available manual that comes with it is awful, probably due largely to + * the fact that it has been emasculated in order to hide information + * that Lucent wants to keep proprietary. The purpose of the HCF seems + * to be to insulate the driver programmer from the Hermes itself so that + * Lucent has an excuse not to release programming in for it. + * + * - Lucent only makes available documentation and code for 'HCF Light' + * which is a stripped down version of HCF with certain features not + * implemented, most notably support for 802.11 frames. + * + * - The HCF code which I have seen blows goats. Whoever decided to + * use a 132 column format should be shot. + * + * Rather than actually use the Lucent HCF library, I have stripped all + * the useful information from it and used it to create a driver in the + * usual BSD form. Note: I don't want to hear anybody whining about the + * fact that the Lucent code is GPLed and mine isn't. I did not actually + * put any of Lucent's code in this driver: I only used it as a reference + * to obtain information about the underlying hardware. The Hermes + * programming interface is not GPLed, so bite me. + */ + +/* + * Size of Hermes & Prism2 I/O space. + */ +#define WI_IOSIZ 0x40 + +/* + * Hermes & Prism2 register definitions + */ + +/* Hermes command/status registers. */ +#define WI_COMMAND 0x00 +#define WI_PARAM0 0x02 +#define WI_PARAM1 0x04 +#define WI_PARAM2 0x06 +#define WI_STATUS 0x08 +#define WI_RESP0 0x0A +#define WI_RESP1 0x0C +#define WI_RESP2 0x0E + +/* Command register values. */ +#define WI_CMD_BUSY 0x8000 /* busy bit */ +#define WI_CMD_INI 0x0000 /* initialize */ +#define WI_CMD_ENABLE 0x0001 /* enable */ +#define WI_CMD_DISABLE 0x0002 /* disable */ +#define WI_CMD_DIAG 0x0003 +#define WI_CMD_ALLOC_MEM 0x000A /* allocate NIC memory */ +#define WI_CMD_TX 0x000B /* transmit */ +#define WI_CMD_NOTIFY 0x0010 +#define WI_CMD_INQUIRE 0x0011 +#define WI_CMD_ACCESS 0x0021 +#define WI_CMD_PROGRAM 0x0022 + +#define WI_CMD_CODE_MASK 0x003F + +/* + * Reclaim qualifier bit, applicable to the + * TX and INQUIRE commands. + */ +#define WI_RECLAIM 0x0100 /* reclaim NIC memory */ + +/* + * ACCESS command qualifier bits. + */ +#define WI_ACCESS_READ 0x0000 +#define WI_ACCESS_WRITE 0x0100 + +/* + * PROGRAM command qualifier bits. + */ +#define WI_PROGRAM_DISABLE 0x0000 +#define WI_PROGRAM_ENABLE_RAM 0x0100 +#define WI_PROGRAM_ENABLE_NVRAM 0x0200 +#define WI_PROGRAM_NVRAM 0x0300 + +/* Status register values */ +#define WI_STAT_CMD_CODE 0x003F +#define WI_STAT_DIAG_ERR 0x0100 +#define WI_STAT_INQ_ERR 0x0500 +#define WI_STAT_CMD_RESULT 0x7F00 + +/* memory handle management registers */ +#define WI_INFO_FID 0x10 +#define WI_RX_FID 0x20 +#define WI_ALLOC_FID 0x22 +#define WI_TX_CMP_FID 0x24 + +/* + * Buffer Access Path (BAP) registers. + * These are I/O channels.
