In typical fashion, getting documentation about this 170 * controller is about as easy as squeezing blood from a stone. Here 171 * is more or less what I know: 172 * 173 * - The Hermes controller is firmware driven, and the host interacts 174 * with the Hermes via a firmware interface, which can change. 175 * 176 * - The Hermes is described in a document called: "Hermes Firmware 177 * WaveLAN/IEEE Station Functions," document #010245, which of course 178 * Lucent will not release without an NDA. 179 * 180 * - Lucent has created a library called HCF (Hardware Control Functions) 181 * though which it wants developers to interact with the card. The HCF 182 * is needlessly complex, ill conceived and badly documented. Actually, 183 * the comments in the HCP code itself aren't bad, but the publically 184 * available manual that comes with it is awful, probably due largely to 185 * the fact that it has been emasculated in order to hide information 186 * that Lucent wants to keep proprietary. The purpose of the HCF seems 187 * to be to insulate the driver programmer from the Hermes itself so that 188 * Lucent has an excuse not to release programming in for it. 189 * 190 * - Lucent only makes available documentation and code for 'HCF Light' 191 * which is a stripped down version of HCF with certain features not 192 * implemented, most notably support for 802.11 frames. 193 * 194 * - The HCF code which I have seen blows goats. Whoever decided to 195 * use a 132 column format should be shot. 196 * 197 * Rather than actually use the Lucent HCF library, I have stripped all 198 * the useful information from it and used it to create a driver in the 199 * usual BSD form. Note: I don't want to hear anybody whining about the 200 * fact that the Lucent code is GPLed and mine isn't. I did not actually 201 * put any of Lucent's code in this driver: I only used it as a reference 202 * to obtain information about the underlying hardware. The Hermes 203 * programming interface is not GPLed, so bite me. 204 */ 205 206 /* 207 * Size of Hermes & Prism2 I/O space. 208 */ 209 #define WI_IOSIZE 0x40 210 #define WI_PCI_CBMA 0x10 /* Configuration Base Memory Address */ 211 212 /* 213 * Hermes & Prism2 register definitions 214 */ 215 216 /* Hermes command/status registers. */ 217 #define WI_COMMAND 0x00 218 #define WI_PARAM0 0x02 219 #define WI_PARAM1 0x04 220 #define WI_PARAM2 0x06 221 #define WI_STATUS 0x08 222 #define WI_RESP0 0x0A 223 #define WI_RESP1 0x0C 224 #define WI_RESP2 0x0E 225 226 /* Command register values. */ 227 #define WI_CMD_BUSY 0x8000 /* busy bit */ 228 #define WI_CMD_INI 0x0000 /* initialize */ 229 #define WI_CMD_ENABLE 0x0001 /* enable */ 230 #define WI_CMD_DISABLE 0x0002 /* disable */ 231 #define WI_CMD_DIAG 0x0003 232 #define WI_CMD_ALLOC_MEM 0x000A /* allocate NIC memory */ 233 #define WI_CMD_TX 0x000B /* transmit */ 234 #define WI_CMD_NOTIFY 0x0010 235 #define WI_CMD_INQUIRE 0x0011 236 #define WI_CMD_ACCESS 0x0021 237 #define WI_CMD_PROGRAM 0x0022 238 239 #define WI_CMD_CODE_MASK 0x003F 240 241 /* 242 * Reclaim qualifier bit, applicable to the 243 * TX and INQUIRE commands. 244 */ 245 #define WI_RECLAIM 0x0100 /* reclaim NIC memory */ 246 247 /* 248 * ACCESS command qualifier bits. 249 */ 250 #define WI_ACCESS_READ 0x0000 251 #define WI_ACCESS_WRITE 0x0100 252 253 /* 254 * PROGRAM command qualifier bits. 255 */ 256 #define WI_PROGRAM_DISABLE 0x0000 257 #define WI_PROGRAM_ENABLE_RAM 0x0100 258 #define WI_PROGRAM_ENABLE_NVRAM 0x0200 259 #define WI_PROGRAM_NVRAM 0x0300 260 261 /* Status register values */ 262 #define WI_STAT_CMD_CODE 0x003F 263 #define WI_STAT_DIAG_ERR 0x0100 264 #define WI_STAT_INQ_ERR 0x0500 265 #define WI_STAT_CMD_RESULT 0x7F00 266 267 /* memory handle management registers */ 268 #define WI_INFO_FID 0x10 269 #define WI_RX_FID 0x20 270 #define WI_ALLOC_FID 0x22 271 #define WI_TX_CMP_FID 0x24 272 273 /* 274 * Buffer Access Path (BAP) registers. 275 * These are I/O channels.
