1189 | * This struct helps tracking the state needed for runtime PM, which puts the |
1190 | * device in PCI D3 state. Notice that when this happens, nothing on the | |
1191 | * graphics device works, even register access, so we don't get interrupts nor | |
1192 | * anything else. | |

1194 | * Every piece of our code that needs to actually touch the hardware needs to |
1195 | * either call intel_runtime_pm_get or call intel_display_power_get with the | |
1196 | * appropriate power domain. | |

1198 | * Our driver uses the autosuspend delay feature, which means we'll only really |
1199 | * suspend if we stay with zero refcount for a certain amount of time. The | |
1200 | * default value is currently very conservative (see intel_init_runtime_pm), but | |
1201 | * it can be changed with the standard runtime PM files from sysfs. | |
c67a470b PZ |
1202 | * |
1203 | * The irqs_disabled variable becomes true exactly after we disable the IRQs and | |
1204 | * goes back to false exactly before we reenable the IRQs. We use this variable | |
1205 | * to check if someone is trying to enable/disable IRQs while they're supposed | |
1206 | * to be disabled. This shouldn't happen and we'll print some error messages in | |
1207 | * case it happens, but if it actually happens we'll also update the variables | |
1208 | * inside struct regsave so when we restore the IRQs they will contain the | |
1209 | * latest expected values. | |
1210 | * | |
