In typical fashion, getting documentation about this 53 * controller is about as easy as squeezing blood from a stone. Here 54 * is more or less what I know: 55 * 56 * - The Hermes controller is firmware driven, and the host interacts 57 * with the Hermes via a firmware interface, which can change. 58 * 59 * - The Hermes is described in a document called: "Hermes Firmware 60 * WaveLAN/IEEE Station Functions," document #010245, which of course 61 * Lucent will not release without an NDA. 62 * 63 * - Lucent has created a library called HCF (Hardware Control Functions) 64 * though which it wants developers to interact with the card. The HCF 65 * is needlessly complex, ill conceived and badly documented. Actually, 66 * the comments in the HCP code itself aren't bad, but the publically 67 * available manual that comes with it is awful, probably due largely to 68 * the fact that it has been emasculated in order to hide information 69 * that Lucent wants to keep proprietary. The purpose of the HCF seems 70 * to be to insulate the driver programmer from the Hermes itself so that 71 * Lucent has an excuse not to release programming in for it. 72 * 73 * - Lucent only makes available documentation and code for 'HCF Light' 74 * which is a stripped down version of HCF with certain features not 75 * implemented, most notably support for 802.11 frames. 76 * 77 * - The HCF code which I have seen blows goats. Whoever decided to 78 * use a 132 column format should be shot. 79 * 80 * Rather than actually use the Lucent HCF library, I have stripped all 81 * the useful information from it and used it to create a driver in the 82 * usual BSD form. Note: I don't want to hear anybody whining about the 83 * fact that the Lucent code is GPLed and mine isn't. I did not actually 84 * put any of Lucent's code in this driver: I only used it as a reference 85 * to obtain information about the underlying hardware. The Hermes 86 * programming interface is not GPLed, so bite me. 87 */ 88 89/* 90 * Size of Hermes & Prism2 I/O space. 91 */ 92#define WI_IOSIZE 0x40 93 94/* 95 * Hermes & Prism2 register definitions 96 */ 97 98/* Hermes command/status registers. */ 99#define WI_COMMAND 0x00 100#define WI_PARAM0 0x02 101#define WI_PARAM1 0x04 102#define WI_PARAM2 0x06 103#define WI_STATUS 0x08 104#define WI_RESP0 0x0A 105#define WI_RESP1 0x0C 106#define WI_RESP2 0x0E 107 108/* Command register values. */ 109#define WI_CMD_BUSY 0x8000 /* busy bit */ 110#define WI_CMD_INI 0x0000 /* initialize */ 111#define WI_CMD_ENABLE 0x0001 /* enable */ 112#define WI_CMD_DISABLE 0x0002 /* disable */ 113#define WI_CMD_DIAG 0x0003 114#define WI_CMD_ALLOC_MEM 0x000A /* allocate NIC memory */ 115#define WI_CMD_TX 0x000B /* transmit */ 116#define WI_CMD_NOTIFY 0x0010 117#define WI_CMD_INQUIRE 0x0011 118#define WI_CMD_ACCESS 0x0021 119#define WI_CMD_PROGRAM 0x0022 120#define WI_CMD_READEE 0x0030 121#define WI_CMD_TEST 0x0038 /* PRISM2 test mode */ 122 123#define WI_CMD_CODE_MASK 0x003F 124 125/* 126 * Reclaim qualifier bit, applicable to the 127 * TX and INQUIRE commands. 128 */ 129#define WI_RECLAIM 0x0100 /* reclaim NIC memory */ 130 131/* 132 * ACCESS command qualifier bits. 133 */ 134#define WI_ACCESS_READ 0x0000 135#define WI_ACCESS_WRITE 0x0100 136 137/* 138 * PROGRAM command qualifier bits. 139 */ 140#define WI_PROGRAM_DISABLE 0x0000 141#define WI_PROGRAM_ENABLE_RAM 0x0100 142#define WI_PROGRAM_ENABLE_NVRAM 0x0200 143#define WI_PROGRAM_NVRAM 0x0300 144 145/* 146 * DEBUG mode options. 147 */ 148#define WI_TEST_MONITOR 0x0B /* monitor mode for testing */ 149 150/* Status register values */ 151#define WI_STAT_CMD_CODE 0x003F 152#define WI_STAT_DIAG_ERR 0x0100 153#define WI_STAT_INQ_ERR 0x0500 154#define WI_STAT_CMD_RESULT 0x7F00 155 156/* memory handle management registers */ 157#define WI_INFO_FID 0x10 158#define WI_RX_FID 0x20 159#define WI_ALLOC_FID 0x22 160#define WI_TX_CMP_FID 0x24 161 162/* 163 * Buffer Access Path (BAP) registers. 164 * These are I/O channels.
