in 1226 * host DRAM. It steers each frame's Tx command (which contains the frame 1227 * data) into one of up to 7 prioritized Tx DMA FIFO channels within the 1228 * device. A queue maps to only one (selectable by driver) Tx DMA channel, 1229 * but one DMA channel may take input from several queues. 1230 * 1231 * Tx DMA FIFOs have dedicated purposes. 1232 * 1233 * For 5000 series and up, they are used differently 1234 * (cf. iwl5000_default_queue_to_tx_fifo in iwl-5000.c): 1235 * 1236 * 0 -- EDCA BK (background) frames, lowest priority 1237 * 1 -- EDCA BE (best effort) frames, normal priority 1238 * 2 -- EDCA VI (video) frames, higher priority 1239 * 3 -- EDCA VO (voice) and management frames, highest priority 1240 * 4 -- unused 1241 * 5 -- unused 1242 * 6 -- unused 1243 * 7 -- Commands 1244 * 1245 * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6. 1246 * In addition, driver can map the remaining queues to Tx DMA/FIFO 1247 * channels 0-3 to support 11n aggregation via EDCA DMA channels. 1248 * 1249 * The driver sets up each queue to work in one of two modes: 1250 * 1251 * 1) Scheduler-Ack, in which the scheduler automatically supports a 1252 * block-ack (BA) window of up to 64 TFDs. In this mode, each queue 1253 * contains TFDs for a unique combination of Recipient Address (RA) 1254 * and Traffic Identifier (TID), that is, traffic of a given 1255 * Quality-Of-Service (QOS) priority, destined for a single station. 1256 * 1257 * In scheduler-ack mode, the scheduler keeps track of the Tx status of 1258 * each frame within the BA window, including whether it's been transmitted, 1259 * and whether it's been acknowledged by the receiving station. The device 1260 * automatically processes block-acks received from the receiving STA, 1261 * and reschedules un-acked frames to be retransmitted (successful 1262 * Tx completion may end up being out-of-order). 1263 * 1264 * The driver must maintain the queue's Byte Count table in host DRAM 1265 * for this mode. 1266 * This mode does not support fragmentation. 1267 * 1268 * 2) FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order. 1269 * The device may automatically retry Tx, but will retry only one frame 1270 * at a time, until receiving ACK from receiving station, or reaching 1271 * retry limit and giving up. 1272 * 1273 * The command queue (#4/#9) must use this mode! 1274 * This mode does not require use of the Byte Count table in host DRAM. 1275 * 1276 * Driver controls scheduler operation via 3 means: 1277 * 1) Scheduler registers 1278 * 2) Shared scheduler data base in internal SRAM 1279 * 3) Shared data in host DRAM 1280 * 1281 * Initialization: 1282 * 1283 * When loading, driver should allocate memory for: 1284 * 1) 16 TFD circular buffers, each with space for (typically) 256 TFDs. 1285 * 2) 16 Byte Count circular buffers in 16 KBytes contiguous memory 1286 * (1024 bytes for each queue). 1287 * 1288 * After receiving "Alive" response from uCode, driver must initialize 1289 * the scheduler (especially for queue #4/#9, the command queue, otherwise 1290 * the driver can't issue commands!): 1291 */ 1292 #define IWM_SCD_MEM_LOWER_BOUND (0x0000) 1293 1294 /** 1295 * Max Tx window size is the max number of contiguous TFDs that the scheduler 1296 * can keep track of at one time when creating block-ack chains of frames. 1297 * Note that "64" matches the number of ack bits in a block-ack packet. 1298 */ 1299 #define IWM_SCD_WIN_SIZE 64 1300 #define IWM_SCD_FRAME_LIMIT 64 1301 1302 #define IWM_SCD_TXFIFO_POS_TID (0) 1303 #define IWM_SCD_TXFIFO_POS_RA (4) 1304 #define IWM_SCD_QUEUE_RA_TID_MAP_RATID_MSK (0x01FF) 1305 1306 /* agn SCD */ 1307 #define IWM_SCD_QUEUE_STTS_REG_POS_TXF (0) 1308 #define IWM_SCD_QUEUE_STTS_REG_POS_ACTIVE (3) 1309 #define IWM_SCD_QUEUE_STTS_REG_POS_WSL (4) 1310 #define IWM_SCD_QUEUE_STTS_REG_POS_SCD_ACT_EN (19) 1311 #define IWM_SCD_QUEUE_STTS_REG_MSK (0x017F0000) 1312 1313 #define IWM_SCD_QUEUE_CTX_REG1_CREDIT_POS (8) 1314 #define IWM_SCD_QUEUE_CTX_REG1_CREDIT_MSK (0x00FFFF00) 1315 #define IWM_SCD_QUEUE_CTX_REG1_SUPER_CREDIT_POS (24) 1316 #define IWM_SCD_QUEUE_CTX_REG1_SUPER_CREDIT_MSK (0xFF000000) 1317 #define IWM_SCD_QUEUE_CTX_REG2_WIN_SIZE_POS (0) 1318 #define IWM_SCD_QUEUE_CTX_REG2_WIN_SIZE_MSK (0x0000007F) 1319 #define IWM_SCD_QUEUE_CTX_REG2_FRAME_LIMIT_POS (16) 1320 #define IWM_SCD_QUEUE_CTX_REG2_FRAME_LIMIT_MSK (0x007F0000) 1321 #define IWM_SCD_GP_CTRL_ENABLE_31_QUEUES (1 << 0) 1322 #define IWM_SCD_GP_CTRL_AUTO_ACTIVE_MODE (1 << 18) 1323 1324 /* Context Data */ 1325 #define IWM_SCD_CONTEXT_MEM_LOWER_BOUND (IWM_SCD_MEM_LOWER_BOUND + 0x600) 1326 #define IWM_SCD_CONTEXT_MEM_UPPER_BOUND (IWM_SCD_MEM_LOWER_BOUND + 0x6A0) 1327 1328 /* Tx status */ 1329 #define IWM_SCD_TX_STTS_MEM_LOWER_BOUND (IWM_SCD_MEM_LOWER_BOUND + 0x6A0) 1330 #define IWM_SCD_TX_STTS_MEM_UPPER_BOUND (IWM_SCD_MEM_LOWER_BOUND + 0x7E0) 1331 1332 /* Translation Data */ 1333 #define IWM_SCD_TRANS_TBL_MEM_LOWER_BOUND (IWM_SCD_MEM_LOWER_BOUND + 0x7E0) 1334 #define IWM_SCD_TRANS_TBL_MEM_UPPER_BOUND (IWM_SCD_MEM_LOWER_BOUND + 0x808) 1335 1336 #define IWM_SCD_CONTEXT_QUEUE_OFFSET(x)\ 1337 (IWM_SCD_CONTEXT_MEM_LOWER_BOUND + ((x) * 8)) 1338 1339 #define IWM_SCD_TX_STTS_QUEUE_OFFSET(x)\ 1340 (IWM_SCD_TX_STTS_MEM_LOWER_BOUND + ((x) * 16)) 1341 1342 #define IWM_SCD_TRANS_TBL_OFFSET_QUEUE(x) \ 1343 ((IWM_SCD_TRANS_TBL_MEM_LOWER_BOUND + ((x) * 2)) & 0xfffc) 1344 1345 #define IWM_SCD_BASE (IWM_PRPH_BASE + 0xa02c00) 1346 1347 #define IWM_SCD_SRAM_BASE_ADDR (IWM_SCD_BASE + 0x0) 1348 #define IWM_SCD_DRAM_BASE_ADDR (IWM_SCD_BASE + 0x8) 1349 #define IWM_SCD_AIT (IWM_SCD_BASE + 0x0c) 1350 #define IWM_SCD_TXFACT (IWM_SCD_BASE + 0x10) 1351 #define IWM_SCD_ACTIVE (IWM_SCD_BASE + 0x14) 1352 #define IWM_SCD_QUEUECHAIN_SEL (IWM_SCD_BASE + 0xe8) 1353 #define IWM_SCD_CHAINEXT_EN (IWM_SCD_BASE + 0x244) 1354 #define IWM_SCD_AGGR_SEL (IWM_SCD_BASE + 0x248) 1355 #define IWM_SCD_INTERRUPT_MASK (IWM_SCD_BASE + 0x108) 1356 #define IWM_SCD_GP_CTRL (IWM_SCD_BASE + 0x1a8) 1357 #define IWM_SCD_EN_CTRL (IWM_SCD_BASE + 0x254) 1358 1359 static inline unsigned int IWM_SCD_QUEUE_WRPTR(unsigned int chnl) 1360 { 1361 if (chnl < 20) 1362 return IWM_SCD_BASE + 0x18 + chnl * 4;
