1152 * This struct tracks the state needed for the Package C8+ feature.
1154 * Package states C8 and deeper are really deep PC states that can only be
1155 * reached when all the devices on the system allow it, so even if the graphics
1156 * device allows PC8+, it doesn't mean the system will actually get to these
1159 * Our driver only allows PC8+ when all the outputs are disabled, the power well
1160 * is disabled and the GPU is idle. When these conditions are met, we manually
1161 * do the other conditions: disable the interrupts, clocks and switch LCPLL
1164 * When we really reach PC8 or deeper states (not just when we allow it) we lose
1165 * the state of some registers, so when we come back from PC8+ we need to
1166 * restore this state. We don't get into PC8+ if we're not in RC6, so we don't
1167 * need to take care of the registers kept by RC6.
1169 * The interrupt disabling is part of the requirements. We can only leave the
1170 * PCH HPD interrupts enabled. If we're in PC8+ and we get another interrupt we
1171 * can lock the machine.
1173 * Ideally every piece of our code that needs PC8+ disabled would call
1174 * hsw_disable_package_c8, which would increment disable_count and prevent the
1175 * system from reaching PC8+. But we don't have a symmetric way to do this for
1176 * everything, so we have the requirements_met and gpu_idle variables. When we
1177 * switch requirements_met or gpu_idle to true we decrease disable_count, and
1178 * increase it in the opposite case. The requirements_met variable is true when
1179 * all the CRTCs, encoders and the power well are disabled. The gpu_idle
1180 * variable is true when the GPU is idle.
1182 * In addition to everything, we only actually enable PC8+ if disable_count
1183 * stays at zero for at least some seconds. This is implemented with the
1184 * enable_work variable. We do this so we don't enable/disable PC8 dozens of
1185 * consecutive times when all screens are disabled and some background app
1186 * queries the state of our connectors, or we have some application constantly
1187 * waking up to use the GPU. Only after the enable_work function actually
1188 * enables PC8+ the "enable" variable will become true, which means that it can
1189 * be false even if disable_count is 0.
1191 * The irqs_disabled variable becomes true exactly after we disable the IRQs and
1192 * goes back to false exactly before we reenable the IRQs. We use this variable
1193 * to check if someone is trying to enable/disable IRQs while they're supposed
1194 * to be disabled. This shouldn't happen and we'll print some error messages in
1195 * case it happens, but if it actually happens we'll also update the variables
1196 * inside struct regsave so when we restore the IRQs they will contain the
1197 * latest expected values.
1199 * For more, read "Display Sequences for Package C8" on our documentation.
