In typical fashion, getting documentation about this 52 * controller is about as easy as squeezing blood from a stone. Here 53 * is more or less what I know: 54 * 55 * - The Hermes controller is firmware driven, and the host interacts 56 * with the Hermes via a firmware interface, which can change. 57 * 58 * - The Hermes is described in a document called: "Hermes Firmware 59 * WaveLAN/IEEE Station Functions," document #010245, which of course 60 * Lucent will not release without an NDA. 61 * 62 * - Lucent has created a library called HCF (Hardware Control Functions) 63 * though which it wants developers to interact with the card. The HCF 64 * is needlessly complex, ill conceived and badly documented. Actually, 65 * the comments in the HCP code itself aren't bad, but the publically 66 * available manual that comes with it is awful, probably due largely to 67 * the fact that it has been emasculated in order to hide information 68 * that Lucent wants to keep proprietary. The purpose of the HCF seems 69 * to be to insulate the driver programmer from the Hermes itself so that 70 * Lucent has an excuse not to release programming in for it. 71 * 72 * - Lucent only makes available documentation and code for 'HCF Light' 73 * which is a stripped down version of HCF with certain features not 74 * implemented, most notably support for 802.11 frames. 75 * 76 * - The HCF code which I have seen blows goats. Whoever decided to 77 * use a 132 column format should be shot. 78 * 79 * Rather than actually use the Lucent HCF library, I have stripped all 80 * the useful information from it and used it to create a driver in the 81 * usual BSD form. Note: I don't want to hear anybody whining about the 82 * fact that the Lucent code is GPLed and mine isn't. I did not actually 83 * put any of Lucent's code in this driver: I only used it as a reference 84 * to obtain information about the underlying hardware. The Hermes 85 * programming interface is not GPLed, so bite me. 86 */ 87 88 /* 89 * Size of Hermes & Prism2 I/O space. 90 */ 91 #define WI_IOSIZE 0x40 92 93 /* 94 * Hermes & Prism2 register definitions 95 */ 96 97 /* Hermes command/status registers. */ 98 #define WI_COMMAND 0x00 99 #define WI_PARAM0 0x02 100 #define WI_PARAM1 0x04 101 #define WI_PARAM2 0x06 102 #define WI_STATUS 0x08 103 #define WI_RESP0 0x0A 104 #define WI_RESP1 0x0C 105 #define WI_RESP2 0x0E 106 107 /* Command register values. */ 108 #define WI_CMD_BUSY 0x8000 /* busy bit */ 109 #define WI_CMD_INI 0x0000 /* initialize */ 110 #define WI_CMD_ENABLE 0x0001 /* enable */ 111 #define WI_CMD_DISABLE 0x0002 /* disable */ 112 #define WI_CMD_DIAG 0x0003 113 #define WI_CMD_ALLOC_MEM 0x000A /* allocate NIC memory */ 114 #define WI_CMD_TX 0x000B /* transmit */ 115 #define WI_CMD_NOTIFY 0x0010 116 #define WI_CMD_INQUIRE 0x0011 117 #define WI_CMD_ACCESS 0x0021 118 #define WI_CMD_PROGRAM 0x0022 119 #define WI_CMD_READEE 0x0030 120 121 #define WI_CMD_CODE_MASK 0x003F 122 123 /* 124 * Reclaim qualifier bit, applicable to the 125 * TX and INQUIRE commands. 126 */ 127 #define WI_RECLAIM 0x0100 /* reclaim NIC memory */ 128 129 /* 130 * ACCESS command qualifier bits. 131 */ 132 #define WI_ACCESS_READ 0x0000 133 #define WI_ACCESS_WRITE 0x0100 134 135 /* 136 * PROGRAM command qualifier bits. 137 */ 138 #define WI_PROGRAM_DISABLE 0x0000 139 #define WI_PROGRAM_ENABLE_RAM 0x0100 140 #define WI_PROGRAM_ENABLE_NVRAM 0x0200 141 #define WI_PROGRAM_NVRAM 0x0300 142 143 /* Status register values */ 144 #define WI_STAT_CMD_CODE 0x003F 145 #define WI_STAT_DIAG_ERR 0x0100 146 #define WI_STAT_INQ_ERR 0x0500 147 #define WI_STAT_CMD_RESULT 0x7F00 148 149 /* memory handle management registers */ 150 #define WI_INFO_FID 0x10 151 #define WI_RX_FID 0x20 152 #define WI_ALLOC_FID 0x22 153 #define WI_TX_CMP_FID 0x24 154 155 /* 156 * Buffer Access Path (BAP) registers. 157 * These are I/O channels.
