1126 | * iDiag PCI config space register access methods: | ||
1127 | * | ||
1128 | * The PCI config space register accessees of read, write, read-modify-write | ||
1129 | * for set bits, and read-modify-write for clear bits to SLI4 PCI functions | ||
1130 | * are provided. In the proper SLI4 PCI function's debugfs iDiag directory, | ||
1131 | * | ||
1132 | * /sys/kernel/debug/lpfc/fn<#>/iDiag | ||
1133 | * | ||
1134 | * the access is through the debugfs entry pciCfg: | ||
1135 | * | ||
1136 | * 1. For PCI config space register read access, there are two read methods: | ||
1137 | * A) read a single PCI config space register in the size of a byte | ||
1138 | * (8 bits), a word (16 bits), or a dword (32 bits); or B) browse through | ||
1139 | * the 4K extended PCI config space. | ||
1140 | * | ||
1141 | * A) Read a single PCI config space register consists of two steps: | ||
1142 | * | ||
1143 | * Step-1: Set up PCI config space register read command, the command | ||
1144 | * syntax is, | ||
1145 | * | ||
1146 | * echo 1 <where> <count> > pciCfg | ||
1147 | * | ||
1148 | * where, 1 is the iDiag command for PCI config space read, <where> is the | ||
1149 | * offset from the beginning of the device's PCI config space to read from, | ||
1150 | * and <count> is the size of PCI config space register data to read back, | ||
1151 | * it will be 1 for reading a byte (8 bits), 2 for reading a word (16 bits | ||
1152 | * or 2 bytes), or 4 for reading a dword (32 bits or 4 bytes). | ||
1153 | * | ||
1154 | * Setp-2: Perform the debugfs read operation to execute the idiag command | ||
1155 | * set up in Step-1, | ||
1156 | * | ||
1157 | * cat pciCfg | ||
1158 | * | ||
1159 | * Examples: | ||
1160 | * To read PCI device's vendor-id and device-id from PCI config space, | ||
1161 | * | ||
1162 | * echo 1 0 4 > pciCfg | ||
1163 | * cat pciCfg | ||
1164 | * | ||
1165 | * To read PCI device's currnt command from config space, | ||
1166 | * | ||
1167 | * echo 1 4 2 > pciCfg | ||
1168 | * cat pciCfg | ||
1169 | * | ||
1170 | * B) Browse through the entire 4K extended PCI config space also consists | ||
1171 | * of two steps: | ||
1172 | * | ||
1173 | * Step-1: Set up PCI config space register browsing command, the command | ||
1174 | * syntax is, | ||
1175 | * | ||
1176 | * echo 1 0 4096 > pciCfg | ||
1177 | * | ||
1178 | * where, 1 is the iDiag command for PCI config space read, 0 must be used | ||
1179 | * as the offset for PCI config space register browse, and 4096 must be | ||
1180 | * used as the count for PCI config space register browse. | ||
1181 | * | ||
1182 | * Step-2: Repeately issue the debugfs read operation to browse through | ||
1183 | * the entire PCI config space registers: | ||
1184 | * | ||
1185 | * cat pciCfg | ||
1186 | * cat pciCfg | ||
1187 | * cat pciCfg | ||
1188 | * ... | ||
1189 | * | ||
1190 | * When browsing to the end of the 4K PCI config space, the browse method | ||
1191 | * shall wrap around to start reading from beginning again, and again... | ||
1192 | * | ||
1193 | * 2. For PCI config space register write access, it supports a single PCI | ||
1194 | * config space register write in the size of a byte (8 bits), a word | ||
1195 | * (16 bits), or a dword (32 bits). The command syntax is, | ||
1196 | * | ||
1197 | * echo 2 <where> <count> <value> > pciCfg | ||
1198 | * | ||
1199 | * where, 2 is the iDiag command for PCI config space write, <where> is | ||
1200 | * the offset from the beginning of the device's PCI config space to write | ||
1201 | * into, <count> is the size of data to write into the PCI config space, | ||
1202 | * it will be 1 for writing a byte (8 bits), 2 for writing a word (16 bits | ||
1203 | * or 2 bytes), or 4 for writing a dword (32 bits or 4 bytes), and <value> | ||
1204 | * is the data to be written into the PCI config space register at the | ||
1205 | * offset. | ||
1206 | * | ||
1207 | * Examples: | ||
1208 | * To disable PCI device's interrupt assertion, | ||
1209 | * | ||
1210 | * 1) Read in device's PCI config space register command field <cmd>: | ||
1211 | * | ||
1212 | * echo 1 4 2 > pciCfg | ||
1213 | * cat pciCfg | ||
1214 | * | ||
1215 | * 2) Set bit 10 (Interrupt Disable bit) in the <cmd>: | ||
1216 | * | ||
1217 | * <cmd> = <cmd> | (1 < 10) | ||
1218 | * | ||
1219 | * 3) Write the modified command back: | ||
1220 | * | ||
1221 | * echo 2 4 2 <cmd> > pciCfg | ||
1222 | * | ||
1223 | * 3. For PCI config space register set bits access, it supports a single PCI | ||
1224 | * config space register set bits in the size of a byte (8 bits), a word | ||
1225 | * (16 bits), or a dword (32 bits). The command syntax is, | ||
1226 | * | ||
1227 | * echo 3 <where> <count> <bitmask> > pciCfg | ||
1228 | * | ||
1229 | * where, 3 is the iDiag command for PCI config space set bits, <where> is | ||
1230 | * the offset from the beginning of the device's PCI config space to set | ||
1231 | * bits into, <count> is the size of the bitmask to set into the PCI config | ||
1232 | * space, it will be 1 for setting a byte (8 bits), 2 for setting a word | ||
1233 | * (16 bits or 2 bytes), or 4 for setting a dword (32 bits or 4 bytes), and | ||
1234 | * <bitmask> is the bitmask, indicating the bits to be set into the PCI | ||
1235 | * config space register at the offset. The logic performed to the content | ||
1236 | * of the PCI config space register, regval, is, | ||
1237 | * | ||
1238 | * regval |= <bitmask> | ||
1239 | * | ||
1240 | * 4. For PCI config space register clear bits access, it supports a single | ||
1241 | * PCI config space register clear bits in the size of a byte (8 bits), | ||
1242 | * a word (16 bits), or a dword (32 bits). The command syntax is, | ||
1243 | * | ||
1244 | * echo 4 <where> <count> <bitmask> > pciCfg | ||
1245 | * | ||
1246 | * where, 4 is the iDiag command for PCI config space clear bits, <where> | ||
1247 | * is the offset from the beginning of the device's PCI config space to | ||
1248 | * clear bits from, <count> is the size of the bitmask to set into the PCI | ||
1249 | * config space, it will be 1 for setting a byte (8 bits), 2 for setting | ||
1250 | * a word(16 bits or 2 bytes), or 4 for setting a dword (32 bits or 4 | ||
1251 | * bytes), and <bitmask> is the bitmask, indicating the bits to be cleared | ||
1252 | * from the PCI config space register at the offset. the logic performed | ||
1253 | * to the content of the PCI config space register, regval, is, | ||
1254 | * | ||
1255 | * regval &= ~<bitmask> | ||
1256 | * | ||
1257 | * Note, for all single register read, write, set bits, or clear bits access, | ||
1258 | * the offset (<where>) must be aligned with the size of the data: | ||
1259 | * | ||
1260 | * For data size of byte (8 bits), the offset must be aligned to the byte | ||
1261 | * boundary; for data size of word (16 bits), the offset must be aligned | ||
1262 | * to the word boundary; while for data size of dword (32 bits), the offset | ||
1263 | * must be aligned to the dword boundary. Otherwise, the interface will | ||
1264 | * return the error: | ||
1265 | * | ||
1266 | * "-bash: echo: write error: Invalid argument". | ||
1267 | * | ||
1268 | * For example: | ||
1269 | * | ||
1270 | * echo 1 2 4 > pciCfg | ||
1271 | * -bash: echo: write error: Invalid argument | ||
1272 | * | ||
1273 | * Note also, all of the numbers in the command fields for all read, write, | ||
1274 | * set bits, and clear bits PCI config space register command fields can be | ||
1275 | * either decimal or hex. | ||
1276 | * | ||
1277 | * For example, | ||
1278 | * echo 1 0 4096 > pciCfg | ||
1279 | * | ||
1280 | * will be the same as | ||
1281 | * echo 1 0 0x1000 > pciCfg | ||
1282 | * | ||
1283 | * And, | ||
1284 | * echo 2 155 1 10 > pciCfg | ||
1285 | * | ||
1286 | * will be | ||
1287 | * echo 2 0x9b 1 0xa > pciCfg | ||

1448 | * registers from the 4K extended PCI config space. | ||
1449 | * | ||

1451 | * This function returns the amount of data that was read (this could be less | ||
1452 | * than @nbytes if the end of the file was reached) or a negative error value. | ||
