In typical fashion, getting documentation about this 138 * controller is about as easy as squeezing blood from a stone. Here 139 * is more or less what I know: 140 * 141 * - The Hermes controller is firmware driven, and the host interacts 142 * with the Hermes via a firmware interface, which can change. 143 * 144 * - The Hermes is described in a document called: "Hermes Firmware 145 * WaveLAN/IEEE Station Functions," document #010245, which of course 146 * Lucent will not release without an NDA. 147 * 148 * - Lucent has created a library called HCF (Hardware Control Functions) 149 * though which it wants developers to interact with the card. The HCF 150 * is needlessly complex, ill conceived and badly documented. Actually, 151 * the comments in the HCP code itself aren't bad, but the publically 152 * available manual that comes with it is awful, probably due largely to 153 * the fact that it has been emasculated in order to hide information 154 * that Lucent wants to keep proprietary. The purpose of the HCF seems 155 * to be to insulate the driver programmer from the Hermes itself so that 156 * Lucent has an excuse not to release programming in for it. 157 * 158 * - Lucent only makes available documentation and code for 'HCF Light' 159 * which is a stripped down version of HCF with certain features not 160 * implemented, most notably support for 802.11 frames. 161 * 162 * - The HCF code which I have seen blows goats. Whoever decided to 163 * use a 132 column format should be shot. 164 * 165 * Rather than actually use the Lucent HCF library, I have stripped all 166 * the useful information from it and used it to create a driver in the 167 * usual BSD form. Note: I don't want to hear anybody whining about the 168 * fact that the Lucent code is GPLed and mine isn't. I did not actually 169 * put any of Lucent's code in this driver: I only used it as a reference 170 * to obtain information about the underlying hardware. The Hermes 171 * programming interface is not GPLed, so bite me. 172 */ 173 174 /* 175 * Size of Hermes & Prism2 I/O space. 176 */ 177 #define WI_IOSIZ 0x40 178 179 /* 180 * Hermes & Prism2 register definitions 181 */ 182 183 /* Hermes command/status registers. */ 184 #define WI_COMMAND 0x00 185 #define WI_PARAM0 0x02 186 #define WI_PARAM1 0x04 187 #define WI_PARAM2 0x06 188 #define WI_STATUS 0x08 189 #define WI_RESP0 0x0A 190 #define WI_RESP1 0x0C 191 #define WI_RESP2 0x0E 192 193 /* Command register values. */ 194 #define WI_CMD_BUSY 0x8000 /* busy bit */ 195 #define WI_CMD_INI 0x0000 /* initialize */ 196 #define WI_CMD_ENABLE 0x0001 /* enable */ 197 #define WI_CMD_DISABLE 0x0002 /* disable */ 198 #define WI_CMD_DIAG 0x0003 199 #define WI_CMD_ALLOC_MEM 0x000A /* allocate NIC memory */ 200 #define WI_CMD_TX 0x000B /* transmit */ 201 #define WI_CMD_NOTIFY 0x0010 202 #define WI_CMD_INQUIRE 0x0011 203 #define WI_CMD_ACCESS 0x0021 204 #define WI_CMD_PROGRAM 0x0022 205 206 #define WI_CMD_CODE_MASK 0x003F 207 208 /* 209 * Reclaim qualifier bit, applicable to the 210 * TX and INQUIRE commands. 211 */ 212 #define WI_RECLAIM 0x0100 /* reclaim NIC memory */ 213 214 /* 215 * ACCESS command qualifier bits. 216 */ 217 #define WI_ACCESS_READ 0x0000 218 #define WI_ACCESS_WRITE 0x0100 219 220 /* 221 * PROGRAM command qualifier bits. 222 */ 223 #define WI_PROGRAM_DISABLE 0x0000 224 #define WI_PROGRAM_ENABLE_RAM 0x0100 225 #define WI_PROGRAM_ENABLE_NVRAM 0x0200 226 #define WI_PROGRAM_NVRAM 0x0300 227 228 /* Status register values */ 229 #define WI_STAT_CMD_CODE 0x003F 230 #define WI_STAT_DIAG_ERR 0x0100 231 #define WI_STAT_INQ_ERR 0x0500 232 #define WI_STAT_CMD_RESULT 0x7F00 233 234 /* memory handle management registers */ 235 #define WI_INFO_FID 0x10 236 #define WI_RX_FID 0x20 237 #define WI_ALLOC_FID 0x22 238 #define WI_TX_CMP_FID 0x24 239 240 /* 241 * Buffer Access Path (BAP) registers. 242 * These are I/O channels.
