Either at all, or because it would impose reduced functionality.
Meaning:
* On 4bpp fb, because those are completely unsupported by the C BB
* On 24bpp fb, because it has limited support for that target format (no alpha blending).
* On 8bpp Linux eInk fb with an inverted palette (that's basically only the K4 ;)).
* On Linux eInk devices w/ no HW inversion support, as that would render NightMode inoperable.
That last point means that it's currently *always* blacklisted on PocketBook, because I don't have a PB device, so I don't know how safe HW inversion would be, meaning none of them are marked as being HW invert capable.
(I was a tiny bit hasty with https://github.com/koreader/koreader-base/pull/912 ;).)
on if it's off.
Because, on the KA1, since wetting the warmth *has* to set the
brightness, it could ;).
Patch only actually needed on Kobo, as all Cervantes devices with warmth
support have a mixer, which mean they *can* set the warmth without
affecting the brightness ;).
* Don't override hw_intensity when we start with the FL off
* And add an insane workaround to make the first toggle behave sanely in this case.
* And also handle the sneakier case where the first toggle happening would not be manual, but triggered by a suspend/resume cycle.
* Make hasNaturalLight* caps safe to call without a device check. (fix#4919)
Make it clear that it's expecting the NTX implementation, though.
* Don't turn the FL on on resume if it was off on suspend
* Make sure turnOn/turnOff actually updates hw_intensity in the process where it matters, instead of just in a short lived fork ;). (fix#4923)
Companion PR to https://github.com/koreader/koreader-base/pull/884
* Basically flags devices known to be stable when using PxP inversion.
* Plus, random fix for #4870 ;).
* A few FrontLight tweaks & cleanups on Kobo:
* Moved the Kobo-specific startup status insanity to Kobo-specific init
* Made turnOff/turnOn frontlight do a smooth ramp down/up
* On Kobo, use turnOff/turnOn for suspend/resume, to get that smooth toggle
* On Kobo, for NaturalLight w/ a mixer, only set warmth for setWarmth, and only set Brightness for setBrightness, otherwise, it tried to set both with not in-sync values, which made the FL widget jittery.
* The Great 8bpp Experiment
Swap to 8bpp on Kobo, because we're 'effing grayscale, for pete's sake!
* Always swap to 8bpp, no matter the launch method.
Because it turned out that, even when restarting Nickel, we had to
restore the expected bitdepth ourselves, because pickel/Nickel didn't do
the job completely.
(I'm going to guess the grayscale flag wasn't getting flipped properly).
* Dither every non-transparent icon to the eInk palette
* Make sure hasBGRFrameBuffer is only enabled when the Kobo fb actually is
@ 32bpp...
* Re-process badly grayscaled icons
* And re-grayscale that one w/ gamma correction so the squares show up
better.
* Allow the fbdepth switch to be disabled (in Developer settings).
Also, allow setting debug mode that way.
Also, forcibly disable verbose logging when disabling debug.
* Update setting name to piggyback on the existing check in reader.lua
* Update icons postprocessing info
* Enable HW dithering on supported devices (Clara HD, Forma; Oasis 2, PW4)
* FileManager and co. (where appropriate, i.e., when covers are shown)
* Book Status
* Reader, where appropriate:
* CRe: on pages whith image content (for over 7.5% of the screen area, should hopefully leave stuff like bullet points or small scene breaks alone).
* Other engines: on user-request (in the gear tab of the bottom menu), via the new "Dithering" knob (will only appear on supported devices).
* ScreenSaver
* ImageViewer
* Minimize repaints when flash_ui is enabled (by, almost everywhere, only repainting the flashing element, and not the toplevel window which hosts it).
(The first pass of this involved fixing a few Button instances whose show_parent was wrong, in particular, chevrons in the FM & TopMenu).
* Hunted down a few redundant repaints (unneeded setDirty("all") calls),
either by switching the widget to nil when only a refresh was needed, and not a repaint,
or by passing the appropritate widget to setDirty.
(Note to self: Enable *verbose* debugging to catch broken setDirty calls via its post guard).
There were also a few instances of 'em right behind a widget close.
* Don't repaint the underlying widget when initially showing TopMenu & ConfigDialog.
We unfortunately do need to do it when switching tabs, because of their variable heights.
* On Kobo, disabled the extra and completely useless full refresh before suspend/reboot/poweroff, as well as on resume. No more double refreshes!
* Fix another debug guard in Kobo sysfs_light
* Switch ImageWidget & ImageViewer mostly to "ui" updates, which will be better suited to image content pretty much everywhere, REAGL or not.
PS: (Almost 💯 commits! :D)
* Fix the Touch input probe on Trilogy devices that depend on the touch_probe_ev_epoch_time quirk (fix#630)
* Expose a "Pageturn button inversion" feature in the Navigation menu (for all devices with keys) (fix#4446)
* Allow ignoring the accelerometer on the Forma (Screen > Ignore accelerometer rotation events; also available from the Gesture Manager) (fix#4451)
* Fix SleepCover handling on the Forma (fix#4457)
* Make isWifiOn a tiny bit more accurate (check the actual WiFi module instead of sdio_wifi_pwr)
* Move all flash related Screen options to the eInk submenu
* Enforce a known rotation on startup, to make sure we handle touch input coordinates properly.
* Proper FrontLight warmth support (thanks to @cairnsh & @pazos in #4291)!
* Fix the PageTurn buttons mapping to match Nickel's defaults
* Properly remap PageTurn buttons depending on the current rotation.
* Actually enable the Mk.7 screen refresh codepath on *all* Mk.7 devices (I'd messed up the device check...).
* Full accelerometer handling (includes a touch of refactoring regarding orientation handling in general).
* Fix insidiously broken USBMS behavior in Nickel after we exit on FW >4.8.
Fix#4291Fix#3002
* Tweak JIT's loopunroll threshold on Kobo 16bpp
To avoid early blacklist of the blitbuffer code on alpha-blending
workloads.
Least terrible workaround we could come up with to "fix" #4137
* gzip kindle/kobo/pb OTA tarballs w/ --rsyncable
Should make them more zsync friendly.
* Make findcalibre actually useful
By setting SEARCH_LIBRARY_PATH when a Calibre tree is found, so that
book paths can properly be constructed.
Users should still very much set it themselves, but at least everything
works as intended when not, instead of mysteriously half-breaking later.
Drop the SetDefaults bits, it appeared to have been added to fix no-ops
detected by Luacheck, and it's actually non-functional, because
SetDefaults doesn't handle saving variables it did not itself assign.
So this was just causing the "Do you want to save new defaults" popup to
show up on exit, but it couldn't actually do anything useful (like, say,
save the new SEARCH_LIBRARY_PATH value).
fix#4082
* Better comments about the state of NaturalLight on the Clara, and how this might translate to the H2O²r2.
re #4015
* Make ScrolltextWidget refresh as "partial" only on actual Scroll events
Moving the cursor should stay "ui", or things gets annoying really fast
;).
re #4084
* Bump base to pickup ZMQ fixes (fix#4086)
* Better KOA2 support
* Fix FL
* Add physical pageturn keys
* Add accelerometer support
* Possibly better NaturalLight handling on the Clara
* Fix WiFi module name used in some(?) Mk7 Kobos
* A bunch of kodev fixes
* Link to the WiKi, it's a bit more explainy ;).
* More WiFi trickery for some HW revs
* Fix Rev2 detection under KSM
That's to future-proof it, the other end of this hasn't made it into
current KSM build yet.
* Resync nickel.sh w/ current rcS
We don't have CPU, but we have PLATFORM, which is based on CPU, so,
that'll do :).
* Go back to using rmmod instead of modprobe -r
Functionally identical on current FW, will potentially avoid getting
outsmarted by modprobe if Kobo ever deigns shipping an actually usable
Linux system one day...
* Don't crash if screensavers directory doesn't exist
c.f., https://www.mobileread.com/forums/showpost.php?p=3706979&postcount=2919
* Switch all initial highlights to "fast" update
i.e., everything that does an invert
Plus a few other things that refresh small UI elements onTap
Re #3130
* Tweak refreshtype for a number of widgets:
* Fix iconbutton dimen
* Make touchmenu flash on close & initial menu popup. Full-screen on close.
* Use flashing updates when opening/closing dictionary popup. Full-screen on close.
* Switch FileManager to partial.
It's mostly text, and we want flash promotion there.
* Make configdialog & menu flash on exit
* Make FLWidget flash on close
* virtualkeyboard: flash on layout change & popup.
* Potentially not that great workaround to ensure we actually see the
highlights in the FM's chevrons
* Flash when closing BookStatus Widget
* Optimize away a quirk of the dual "fast" update in touchmenu
* Promote updates to flashing slightly more agressively.
* Document what each refreshtype actually does.
With a few guidelines on their optimal usecases.
* Switch remaining scheduleIn(0.0) to nextTick()
* Tighter scheduling timers
Shaving a hundred ms off UI callbacks...
* Cache FFI C Library namespace
* Ask MuPDF to convert pixmaps to BGR on Kobo
Fix#3949
* Mention koxtoolchain in the README
re #3972
* Kindle: Handle *all* fonts via EXT_FONT_DIR instead of bind mounts insanity
* Make black flashes in UI elements user-configurable
(All or nothing).
* Jot down some random KOA2 sysfs path
* Trim unneeded stuff from startup script
I was somehow convinced I'd already done that...
While we're there, explain why we need to siphon those specific vars
* Fix a stray eth0
-> $INTERFACE
* Be very very sure we have INTERFACE set in our env
re #3936
* Make getFirmwareVersion less fragile on Kobo
Not that we actually use it right now, but, still. :D
* Use the same syntax as the PRODUCT check
* Actually implement getProductId
Instead of a stray c/p ^^
* Properly identify the Rev2/Mark7 variants of existing devices
Namely, the H2O² and Aura SE
Not that the H2O²r2 support is still broken, this just allows us to
implement it cleanyl without breaking handling of the original H2O²
re #3925
* Tweak sleeps a bit around Kobo WiFi modules...
See if that jog things up (re #3936)
* Try harder not to suspend with WiFi on on Kobos
Because otherwise, things go boom. (re #3936)
* Fix order of tar args
Otherwise, current tar versions abort
* Unbreak Kobo IR grid resume workaround
Regression after f402ee5f6f
I'm going to assume my H2O is really, really weird, because that
commit's more than a year old o_O.
Add support in nickel_conf to save/retrieve setting of
'autoColorEnabled', which is the automatic warmth feature in
Nickel. We do not support reading of 'BedTime', because it is encoded
as a QVariant. This setting is hence saved/loaded solely in/from
G_reader_settings.
This is the first step to support "automatic warmth", meaning that
warmth will be set according to the current time. The user can set a
"bedtime" at which warmth should be maximal. Warmth will increase
towards approaching bedtime and decrease afterwards.
Add new members 'auto_warmth' and 'max_warmth_hour' which tell if this
feature is enabled and the "bedtime", resp. Add a method
'calculateAutoWarmth' which will set the current warmth according to
the current time. The progression is linear but not symmetrical: we
start 5h before "bedtime", but turn back warmth to '0' 2h after it, to
make sure that warmth is '0' in the morning.
For automatically setting warmth in the background we use the
backgroundrunner plugin, because not only is it more comfortable to
use, but we also cannot require 'uimanager' during device
initialization.
For warmth and/or brightness = 0, we need to make sure that the
red/green/white LEDs are actually turned off, regardless of the values
for gain/offset.
If the device has natural light support (currently only KA1), use the
sysfs interface instead of the ioctl-based one. It might also be
usable on other Kobo devices for setting brightness without natural
light, but since I cannot test this, this is currently restricted to
the KA1.
By default, the ioctl interface is used for accessing the
frontlight. However, the ioctl interface has two problems: the overall
brightness seems to be lower (issue #2321), and it does not support
the natural light support from the Kobo Aura One (issue #2285). This
interface is the first step to fix both these issues.
From observing Nickel's behavior, it appears the white/green/red
intensities are roughly linear dependent on the 4th root of brightness
and warmth values. This leads to a very quick increase of the
intensities for lower brightness/warmth values, which then saturate
for larger ones. The values for gain/offset were determined by a
simple linear regression, but the plan is to create a widget so that
users may adapt these values to their liking.
* frontlight on kobo: a few fixes
Rewritten to not update NickelConf on every change, and never
if KOBO_SYNC_BRIGHTNESS_WITH_NICKEL = false.
Reintroduce global settings frontlight_intensity and
is_frontlight_on to keep level and state across koreader
sessions.
Fix a few of the remaining issues on kobo light.
Ensure settings are saved when rebooting/powering off from
File browser.
* Ensure untoggle works when starting with light off
* Put back fl_min=0 as it is for all other devices (the idea
fl_min should be 1 and toggling managed some other way is
not implemented in current code).
* Fix a few frontlightwidget issues
* Use PluginShare to exchange data between plugins
* Remove legacy code in reader.lua and kobo/device.lua, and move KOBO_LIGHT_ON_START to kobo/powerd.lua
* A better sync config logic
* Consider kobo without hardware frontlight toggle
* update frontlight widget once toggle is tapped.
* Start battery stat plugin
* BatteryStat & kobolight
* Several minor improvements
* Remove a useless function
* flush settings
* Some review feedbacks
* Resolve review comments
* Remaining Minutes -> Remaining Hours
* Add dump_file

* sleeping percentage is still negative
* Read settings
* Do not need to change was_suspending and was_charging
* Typo
* Remove debugging flag
* Not charging should happen before suspend
* Resolve review comments
* was_suspend and was_charging should be updated each time in onCallback()
Disable wakeup_count handling, that's often causing more harm than
anything else...
Nickel doesn't even use it, that should have been a hint ;).
Make the logging slightly less confusing.
Add commented out debug features (dumping relevant dmesg output).
