  • Implement basic QPA that Qt applications can use to directly target using the new GUI API
  • Implement pen hover support
  • Switch all the tarnish screen interactions over to using window based screen access
    • Application splash screens
    • Notifications
    • Suspend image
    • Quitting screens
  • Allow applications to get direct FB access with OXIDE_PRELOAD_EXPOSE_FB=1
  • Allow applications to get direct input access with OXIDE_PRELOAD_EXPOSE_INPUT=1
  • Replace current gesture handling with QTouchEvent based one
  • Upgrade sentry-native to 0.6.5
  • Remove application chroot capabilities
  • Add power sysfs handling to preload
  • Fix issue where quitting a preload can throw free(): invalid pointer and keep the application from stopping in the qpa
  • Fix issue where input freezes things running in the preload. This is most noticeable with rmfm and nao as sometimes simple will freeze when you tap a button
  • Fix issue where raise/lower doesn't always result in a z sort change
  • Fix issue where ctrl-c causes a segfault in the qpa
  • Fix issue where sometimes input just stops working (Could be the freezing)
  • Fix memory leak due to windows not being deleted after they have been closed
  • Fix issue where windows can stick around even if the process that created it is no longer running, and the process
    group is empty
  • Fix issue where sometimes windows don't display properly and stay blank
  • Update task switcher to use new window mechanism instead of awkward screen copy dance
  • Fix splashscreens being hidden before the application window displays
  • Fix tablet events not being sent to resized windows
  • Fix x/y location of pen events in preload now that the coordinate origin is top left
  • Fix x/y location of pen events in qpa now that the coordinate origin is top left
  • Resolve performance issue introduced by properly rotating tablet location
  • Fix touch events in QPA not working when on a resized window
  • Fix QImage::pixelColor: coordinate (1861,0) out of range error on tarnish startup
  • Fix issue where things freeze on startup while starting the first application
  • Fix issue on first boot where things don't display properly until you restart tarnish
  • Fix ctrl-c sometimes resulting in tarnish being killed after stopping the first running application
  • Fix tablet events only partially working on resized windows

  • Flush out liboxide documentation
  • Fix issue where preload sometimes freezes while sending input events
  • Fix issue where screen flashes when sitting on the lockscreen for a while
  • Implement on-screen keyboard for things like ReTerm
  • Update notifications to stay on screen for longer and allow clicking them to actually work
  • Add power menu application that shows when the power button is held down
  • Implement MXCFB_SET_AUTO_UPDATE_MODE handling
  • Implement different MXCFB_SET_UPDATE_SCHEME mechanisms
  • Update task-switcher to allow switching between windows
  • Implement LD_PRELOAD library to automatically wrap applications
    • Get libremarkable based applications working
      • DOOMarkable
      • Plato
      • Chessmarkable
      • whiteboard-hypercard
        • Nothing is drawn to the framebuffer on startup, Several calls to MXCFB_SEND_UPDATE, so there should be stuff drawn, but there is nowhere near enough calls for the animation that plays out.
        • High CPU usage that is only present when using the preload
        • Drawing on the screen works
        • With RUST_LOG=debug set it appears that the qrcode thread doesn't start
        • OXIDE_PRELOAD_EXPOSE_INPUT=1 doesn't help
        • OXIDE_PRELOAD_EXPOSE_FB=1 allows the animation to load, but breaks input
        • There is one 1x1 repaint sent after the [paint mouldings] drawingUI... log line, and then no more, so something is freezing up in here: https://github.com/fenollp/reMarkable-tools/blob/7fcad46dc11bc18ab25b2fbaa2403de07365c23a/marauder/src/bin/whiteboard.rs#L689
    • Get LD_PRELOAD library for qt applications to inject QPA
      • Get xochitl working - preload.qt
        • Pen input not working to draw
        • If just using base preload, no input works, and will only load without OXIDE_PRELOAD_NO_QAPP
        • Lots of errors related to attempts to create children for a parent on a different thread, where the parent is QTcpSocket
      • Get calculator working - preload.qt
      • Get wikipedia working - preload.qt
      • Get recrossable working - OXIDE_PRELOAD_NO_QAPP=1
    • Get KOReader working - KO_DONT_SET_DEPTH=1
    • Get script based applications (things using simple for example working)
    • Get yaft working Unfinished TODO can cause Bus error timower/rM2-stuff#17
      • Pen input not being handled
    • Get tilem working Unfinished TODO can cause Bus error timower/rM2-stuff#17
    • Get rmkit based applications working
    • Get netsurf working
    • Get ReTerm working
      • Crashes with access denied to /dev/fb0. This appears to be a pwrite on /dev/fb0. Potentially trying to write outside of the sealed area?

      • It might be better to just write a driver
  • Get folly working
  • Get sill working
    • Same issues as folly
