In typical fashion, getting documentation about this 141 * controller is about as easy as squeezing blood from a stone. Here 142 * is more or less what I know: 143 * 144 * - The Hermes controller is firmware driven, and the host interacts 145 * with the Hermes via a firmware interface, which can change. 146 * 147 * - The Hermes is described in a document called: "Hermes Firmware 148 * WaveLAN/IEEE Station Functions," document #010245, which of course 149 * Lucent will not release without an NDA. 150 * 151 * - Lucent has created a library called HCF (Hardware Control Functions) 152 * though which it wants developers to interact with the card. The HCF 153 * is needlessly complex, ill conceived and badly documented. Actually, 154 * the comments in the HCP code itself aren't bad, but the publically 155 * available manual that comes with it is awful, probably due largely to 156 * the fact that it has been emasculated in order to hide information 157 * that Lucent wants to keep proprietary. The purpose of the HCF seems 158 * to be to insulate the driver programmer from the Hermes itself so that 159 * Lucent has an excuse not to release programming in for it. 160 * 161 * - Lucent only makes available documentation and code for 'HCF Light' 162 * which is a stripped down version of HCF with certain features not 163 * implemented, most notably support for 802.11 frames. 164 * 165 * - The HCF code which I have seen blows goats. Whoever decided to 166 * use a 132 column format should be shot. 167 * 168 * Rather than actually use the Lucent HCF library, I have stripped all 169 * the useful information from it and used it to create a driver in the 170 * usual BSD form. Note: I don't want to hear anybody whining about the 171 * fact that the Lucent code is GPLed and mine isn't. I did not actually 172 * put any of Lucent's code in this driver: I only used it as a reference 173 * to obtain information about the underlying hardware. The Hermes 174 * programming interface is not GPLed, so bite me. 175 */ 176 177 /* 178 * Size of Hermes & Prism2 I/O space. 179 */ 180 #define WI_IOSIZE 0x40 181 #define WI_PCI_CBMA 0x10 /* Configuration Base Memory Address */ 182 183 /* 184 * Hermes & Prism2 register definitions 185 */ 186 187 /* Hermes command/status registers. */ 188 #define WI_COMMAND 0x00 189 #define WI_PARAM0 0x02 190 #define WI_PARAM1 0x04 191 #define WI_PARAM2 0x06 192 #define WI_STATUS 0x08 193 #define WI_RESP0 0x0A 194 #define WI_RESP1 0x0C 195 #define WI_RESP2 0x0E 196 197 /* Command register values. */ 198 #define WI_CMD_BUSY 0x8000 /* busy bit */ 199 #define WI_CMD_INI 0x0000 /* initialize */ 200 #define WI_CMD_ENABLE 0x0001 /* enable */ 201 #define WI_CMD_DISABLE 0x0002 /* disable */ 202 #define WI_CMD_DIAG 0x0003 203 #define WI_CMD_ALLOC_MEM 0x000A /* allocate NIC memory */ 204 #define WI_CMD_TX 0x000B /* transmit */ 205 #define WI_CMD_NOTIFY 0x0010 206 #define WI_CMD_INQUIRE 0x0011 207 #define WI_CMD_ACCESS 0x0021 208 #define WI_CMD_PROGRAM 0x0022 209 210 #define WI_CMD_CODE_MASK 0x003F 211 212 /* 213 * Reclaim qualifier bit, applicable to the 214 * TX and INQUIRE commands. 215 */ 216 #define WI_RECLAIM 0x0100 /* reclaim NIC memory */ 217 218 /* 219 * ACCESS command qualifier bits. 220 */ 221 #define WI_ACCESS_READ 0x0000 222 #define WI_ACCESS_WRITE 0x0100 223 224 /* 225 * PROGRAM command qualifier bits. 226 */ 227 #define WI_PROGRAM_DISABLE 0x0000 228 #define WI_PROGRAM_ENABLE_RAM 0x0100 229 #define WI_PROGRAM_ENABLE_NVRAM 0x0200 230 #define WI_PROGRAM_NVRAM 0x0300 231 232 /* Status register values */ 233 #define WI_STAT_CMD_CODE 0x003F 234 #define WI_STAT_DIAG_ERR 0x0100 235 #define WI_STAT_INQ_ERR 0x0500 236 #define WI_STAT_CMD_RESULT 0x7F00 237 238 /* memory handle management registers */ 239 #define WI_INFO_FID 0x10 240 #define WI_RX_FID 0x20 241 #define WI_ALLOC_FID 0x22 242 #define WI_TX_CMP_FID 0x24 243 244 /* 245 * Buffer Access Path (BAP) registers. 246 * These are I/O channels.
