1286 | /* |
1287 | * This struct tracks the state needed for the Package C8+ feature. | |
1288 | * | |
1289 | * Package states C8 and deeper are really deep PC states that can only be | |
1290 | * reached when all the devices on the system allow it, so even if the graphics | |
1291 | * device allows PC8+, it doesn't mean the system will actually get to these | |
1292 | * states. | |
1293 | * | |
1294 | * Our driver only allows PC8+ when all the outputs are disabled, the power well | |
1295 | * is disabled and the GPU is idle. When these conditions are met, we manually | |
1296 | * do the other conditions: disable the interrupts, clocks and switch LCPLL | |
1297 | * refclk to Fclk. | |
1298 | * | |
1299 | * When we really reach PC8 or deeper states (not just when we allow it) we lose | |
1300 | * the state of some registers, so when we come back from PC8+ we need to | |
1301 | * restore this state. We don't get into PC8+ if we're not in RC6, so we don't | |
1302 | * need to take care of the registers kept by RC6. | |
1303 | * | |
1304 | * The interrupt disabling is part of the requirements. We can only leave the | |
1305 | * PCH HPD interrupts enabled. If we're in PC8+ and we get another interrupt we | |
1306 | * can lock the machine. | |
1307 | * | |
1308 | * Ideally every piece of our code that needs PC8+ disabled would call | |
1309 | * hsw_disable_package_c8, which would increment disable_count and prevent the | |
1310 | * system from reaching PC8+. But we don't have a symmetric way to do this for | |
1311 | * everything, so we have the requirements_met and gpu_idle variables. When we | |
1312 | * switch requirements_met or gpu_idle to true we decrease disable_count, and | |
1313 | * increase it in the opposite case. The requirements_met variable is true when | |
1314 | * all the CRTCs, encoders and the power well are disabled. The gpu_idle | |
1315 | * variable is true when the GPU is idle. | |
1316 | * | |
1317 | * In addition to everything, we only actually enable PC8+ if disable_count | |
1318 | * stays at zero for at least some seconds. This is implemented with the | |
1319 | * enable_work variable. We do this so we don't enable/disable PC8 dozens of | |
1320 | * consecutive times when all screens are disabled and some background app | |
1321 | * queries the state of our connectors, or we have some application constantly | |
1322 | * waking up to use the GPU. Only after the enable_work function actually | |
1323 | * enables PC8+ the "enable" variable will become true, which means that it can | |
1324 | * be false even if disable_count is 0. | |
1325 | * | |
1326 | * The irqs_disabled variable becomes true exactly after we disable the IRQs and | |
1327 | * goes back to false exactly before we reenable the IRQs. We use this variable | |
1328 | * to check if someone is trying to enable/disable IRQs while they're supposed | |
1329 | * to be disabled. This shouldn't happen and we'll print some error messages in | |
1330 | * case it happens, but if it actually happens we'll also update the variables | |
1331 | * inside struct regsave so when we restore the IRQs they will contain the | |
1332 | * latest expected values. | |
1333 | * | |
1334 | * For more, read "Display Sequences for Package C8" on our documentation. | |
