* Kobo: Make sure checkUnexpectedWakeup won't run between scheduled
suspend calls
Because of the suspend_wait_timeout, a previously scheduled check *could* shortcircuit a suspend scheduled a tiny bit later by a real Power event.
This led to fun breakage when you plugged/unplugged a "sleeping" device, for instance.
Fix#9457
* And clear up the unexpected_wakeup_count semantics
Bits of an older design seeped through and were causing weird corner-cases...
* AutoSuspend: Use the canSuspend devcap check instead of reinventing the wheel.
* Device & UIManager: Cleanup canSuspend devcap check related stuff to avoid boilerplate code.
(It also now defaults to no, and is explicitly set by device implementations where supported).
* AutoSuspend: Re-engage suspend/shutdown timers when fully charged.
This restores the existing behavior pre #9036
(c.f., https://github.com/koreader/koreader/pull/9258#issuecomment-1167672356)
* SDL: Unbreak the fake suspend behavior so that it actually works.
Tweak the default screensaver message to remind users that Power is bound to F2.
(Fix#9262)
* AutoSuspend: Re-engage suspend/shutdown timers on unplug.
This matters on Kobo, because the unexpected wakeup guard might have stopped the suspend timer.
Commonize fullscreen code across different devices.
Add fullscreen toggle on SDL desktop targets.
Expose the toggle to the dispatcher and map it to F11.
Hide touchmenu when resizing.
* Disable all non power management related input during suspend. (This prevents wonky touch events from being tripped when closing a sleep cover on an already-in-suspend device, among other things).
* Kobo: Use our WakeupMgr instance, not the class.
* WakupMgr: split `removeTask` in two:
* `removeTask`, which *only* takes a queue index as input, and only removes a single task. Greatly simplifies the function (i.e., it's just a `table.remove`).
* `removeTasks`, which takes an epoch or a cb ref, and removes *every* task that matches.
* Both of these will also *always* re-schedule the next task (if any) on exit, since we can have multiple WakeupMgr tasks queued, but we can only have a single RTC wake alarm set ;).
* `wakeupAction` now takes a `proximity` argument, which it passes on to its `validateWakeupAlarmByProximity` call, allowing call sites to avoir having to duplicate that call themselves when they want to use a custom proximity window.
* `wakeupAction` now re-schedules the next task (if any) on exit.
* Simplify `Kobo:checkUnexpectedWakeup`, by removing the duplicate `WakerupMgr:validateWakeupAlarmByProximity` call, now that we can pass a proximity window to `WakeuoMgr:wakeupAction`.
* The various network activity timeouts are now halved when autostandby is enabled.
* Autostandby: get rid of the dummy deadline_guard task, as it's no longer necessary since #9009.
* UIManager: The previous change allows us to simplify `getNextTaskTimes` into a simpler `getNextTaskTime` variant, getting rid of a table & a loop.
* ReaderFooter & ReaderHeader: Make sure we only perform a single refresh when exiting standby.
* Kobo: Rewrite sysfs writes to use ANSI C via FFI instead of stdio via Lua, as it obscured some common error cases (e.g., EBUSY on /sys/power/state).
* Kobo: Simplify `suspend`, now that we have sane error handling in sysfs writes.
* Kobo.powerd: Change `isCharging` & `isAuxCharging` behavior to match the behavior of the NTX ioctl (i.e., Charging == Plugged-in). This has the added benefit of making the AutoSuspend checks behave sensibly in the "fully-charged but still plugged in" scenario (because being plugged in is enough to break PM on `!canPowerSaveWhileCharging` devices).
* AutoSuspend: Disable our `AllowStandby` handler when auto standby is disabled, so as to not interfere with other modules using `UIManager:allowStandby` (fix#9038).
* PowerD: Allow platforms to implement `isCharged`, indicating that the battery is full while still plugged in to a power source (battery icon becomes a power plug icon).
* Kobo.powerd: Implement `isCharged`, and kill charging LEDs once battery is full.
* Kindle.powerd: Implement `isCharged` on post-Wario devices. (`isCharging` is still true in that state, as it ought to).
* Handle said rotation shenanigans inside ScreenSaver & ScreenSaverWidget, which allows a more targeted approach; and prevents said rotation from affecting other widgets. (Also, gets rid of duplicated code).
* Handle the corner-case or exiting early from a "keep on screen for n sec" screensaver better, by unscheduling the extra refresh, since an early tap took care of that already.
Allows the device to go into standby (if available in `/sys/power/state`) to save power.
Adds an entry in the device menu to tune the timeout for standby.
(Shows total standby- and suspend-time in system statistics.)
* Only toggle nightmode via the grayscale fb info flag on Kindle
Most NTX boards require elaborate trickery (see fbdepth) to actually
send a vput ioctl without the driver screwing with the rotation behind
your back.
This was causing spurious hardware rotations on exit on most Kobo
devices, something which might have gone mostly unnoticed, as current
Nickel versions will sanitize it on startup.
A simple repro was instead to start an USBMS session, as that exits
KOReader and restarts it without going through fbdepth again ;).
* Rejig frontlight warmth API to more closely match the existing API, and, hopefully, clarify some of its quirks, and reduce boilerplate and duplicate code in platform implementations.
* Tweak Kindle:setDateTime to prefer using the platform's custom script, as in interacts better with the stock UI. And make the fallbacks handle old busybox versions better.
* Add Kindle PW5 support ;).
* Add warmth support to the Kindle platform.
* Random TextBoxWidget cleanups: make sure we immediately free destroyed instances.
* FrontLightWidget: Refactor to make it slightly less obnoxious to grok and update; i.e., separate layout from update, and properly separate brightness from warmth handling. Move to simpler widgets instead of reinventing the wheel.
* TextBoxWidgets: Implement `setText` to match TextWidget's API, as some callers may be using the two interchangeably (i.e., Button).
* NaturalLightWidget: Make sure we pass a string to InputText
* InputText: Add debug guards to catch bad callers not passing strings ;).
widget
Since we only use a single icon, we have to take a few shortcuts:
* The icon itself is computed based on the average of both batteries.
* The actual value is the sum of both batteries.
* Much like everywhere else, charging means the *aux* battery charging
(i.e., connected to a power source).
Re #8741, which does the same for ReaderHeader.
* The first few capacity reads after connecting to the cover may fail
* The PowerCover may trigger spurious move/add usb_plug uevent,
which translate into Charging events for us.
Instead of blindly lighting up the charging LED on those,
check if the device is actually charging, first.
Implement it on the Kobo Sage, for the PowerCover
TouchMenu: Display auxiliary battery status
Kobo: More accurately report the PowerCover's charging status
i.e., try to actually figure out if the auxiliary battery is charging
instead of just checking the reader's battery (because that one will
often swap between the charging and discharging state as it drains the
aux battery...).
PowerD: Use a cached timestamp when doing battery pull checks
screen.
Otherwise, on the Sage, weird flash glitches may happen, depending on
what was on screen...
(e.g., there's some weird update merging shenanigans going on
despite those updates being flagged NO_MERGE...).
cores
* Only keep a single core online most of the time.
* Device: Add an enableCPUCores method to allow controlling the amount of
online CPU cores.
* Move the initial core onlining setup to Kobo:init, instead of the startup script.
* Enable two CPU cores while hinting new (e.g., cache miss) pages in PDF land.
* Enable two CPU cores while processing book metadata.
* Drive-by fix to isolate the DocCache pressure check to KoptInterface
and actually apply it when it matters most (e.g., k2pdfopt stuff).
We should always unschedule suspend before scheduling it again (i.e.,
use rescheduleSuspend ;)).
Fix#8097 (many thanks to @Mel-kior for the detailed repro!)
We've managed to trip a few of those on dimen fields post-init but
pre-paintTo in a few weird coner-cases, a point at which dimen is often
nil.
ConfigDialog: Deal with that very thing in update()
Fix#7656
* LuaSettings/DocSettings: Updated readSetting API to allow proper initialization to default.
Use it to initialize tables, e.g., fixing corner-cases in readerFooter that could prevent settings from being saved.
(Fixes an issue reported on Gitter).
* LuaSettings/DocSettings: Add simpler API than the the flip* ones to toggle boolean settings.
* Update LuaSettings/DocSettigns usage throughout the codebase to use the dedicated boolean methods wher appropriate, and clean up some of the more mind-bending uses.
* FileChooser: Implement an extended default exclusion list (fix#2360)
* ScreenSaver: Refactor to avoid the pile of kludges this was threatening to become. Code should be easier to follow and use, and fallbacks now behave as expected (fix#4418).
* Make switching *back* to the default DPI via auto actually work
properly.
eg., by actually setting DPI back to defaults, and clearing the override
flag.
* Bump base to pickup https://github.com/koreader/koreader-base/pull/1258
* Warn on restart if the startup script has been updated, because a restart will not reload it.
* Also warn right after the update if it contained a startup script update...
* Enable AutoSuspend plugin on rM
Fix#6769
Re: #6028
* Use the PowerEvent handler on rM
It makes much more sense than the fire & forget & hope for the best
approach copied from the Kindle platform, because we *are* controlling
suspend ourselves (mostly), unlike on Kindle ;).
Fix#6676
* Enable HW inversion on the rM
I mean, we kinda forgot to ever test that, but I don't really see why it
wouldn't work ;).
* In icons mode, just use two different icons to display Wi-Fi status
* Enable Wi-Fi status icon on Kobo & Cervantes, too
* Refresh footer on (dis)connect if the Wi-Fi status item is enabled
