Generally improve brightness dumpsys. For the recent spate of autobrightness bugs, being able to determine both current state of the display brightness and the overall situational context of the device (e.g. ALS readings) is critical to quick diagnosis. This tidies up the logs and adds some more state information so we have more context about the situation the device is in.

Reset auto-brightness on new BrightnessConfiguration In theory, the newly pushed configuration should take into account all of the brightness adjustments that the user has made throughout the day, so applying any part of the short term model on top of that would be effectively adjusting for them twice over. To avoid getting into this state, we reset the short-term model. Bug: 78910182 Test: Manual Change-Id: I52121eac84eb8ceb914a94a95af2f174ab2f5b73

Fixed auto-brightness when ALS malfunctions. When the ALS is broken or misbehaving, auto-brightness might get stuck in a state where it completely ignores user data points; this fixes the issue, and reverts to manual brightness whenever auto-brightness can't be used reliably.

Reset brightness adjustment when user sets brightness directly. If the user has a non-zero brightness adjustment then short-term model returns an incorrect value after they make a direct change to the brightness with auto-brightness on, which then looks like the auto-brightness is ignoring their input. To avoid this , if they're making a direct change to auto-brightness go ahead and reset the brightness adjustment. Change-Id: I257a6ecc7ca3df0e610710df19d81a65b009af45 Fixes: 72506596 Test: manual

Slider always represents absolute brightness Currently the slider represents a gamma adjustment to the brightness curve when auto brightness is enabled and the absolute screen brightness when it's not. This is a fairly confusing behavior to most people, so this consolidates them to a single behavior: the slider always represents the current brightness and auto-brightness will automatically adjust it. This also moves a bunch of the brightness methods from PowerManager over to DisplayManager, since it's really the DisplayPowerController that's responsible for determining and setting the display brightness.

Add an API for setting a new brightness curve. In addition, this also provides multiple strategies for mapping from ambient room brightness in lux to display brightness. The default one is the classic strategy, where we map directly from lux to backlight brightness in an arbitrary unit. The newer and preferred strategy is to use the physical brightness of the display, but requires that the brightness properties of the display are appropriately configured.

Add new "fast" filter for ambient light. The slow filter wasn't converging fast enough when we shortened the debounce timings but we still want it to ensure there's a long term change happening, so add a new filter that converges much faster. This new fast filter is just a weighted sliding window just like the slow filter, but it has a significantly smaller horizon.

TwilightService v2.0 - Switched to using CalendarAstronomer for more accurate sunrise/sunset times. - Exposed sunrise/sunset times via TwilightState so that clients can track the current twilight period and perform their own interpolations. - Adopted LocationRequest API for fused location updates: (low power, min 1h, max 10m). - TwilightService is now only activated when a listener is registered, minimizing impact to system health on platforms / configurations where twilight state is not needed.

SysUI Tuner: Night mode v3 TwilightService: - Add support for locking on/off twilight globally - Change twilight state to have float amount rather than having clients calculate it using the sunrise/set values - State controlled through secure setting - Override mode which locks to a state for a couple hours then resets - Add broadcast for SysUI to listen to Brightness/Power: - Updates to handle TwilightService changes - Added secure setting to control whether or not to use twilight when calculating brightness. Tuner: - UI Overhall - NightModeController will set the values of the custom color matrix taking into account the current twilight service state and any custom calibration set by the user. - Probably other stuff.

Allow dreams to control screen state and brightness. Added setDozeScreenState() and setDozeScreenBrightness() methods to DreamService. The values specified here only take effect once startDozing is called and can be changed while dozing. This required some significant rework of the display power controller but the result seems quite nice and better represents the policy we want to apply. Changed the test dream a little bit to make it flash the screen every minute using the new functions. Bug: 15903322 Change-Id: I83bcc34503f1b87727d2b2b3c0ef08507f9f0808
