iBasso DX50/DX90: Major code cleanup and reorganization.

2015-02-02T20:57:55+00:00

Reorganization

- Separated iBasso devices from PLATFORM_ANDROID. These are now standlone
  hosted targets. Most device specific code is in the
  firmware/target/hosted/ibasso directory.
- No dependency on Android SDK, only the Android NDK is needed.
  32 bit Android NDK and Android API Level 16.
- Separate implementation for each device where feasible.

Code cleanup

- Rewrite of existing code, from simple reformat to complete reimplementation.
- New backlight interface, seperating backlight from touchscreen.
- Rewrite of device button handler, removing unneeded code and fixing memory
  leaks.
- New Debug messages interface logging to Android adb logcat (DEBUGF, panicf,
  logf).
- Rewrite of lcd device handler, removing unneeded code and fixing memory leaks.
- Rewrite of audiohw device handler/pcm interface, removing unneeded code and
  fixing memory leaks, enabling 44.1/48kHz pthreaded playback.
- Rewrite of power and powermng, proper shutdown, using batterylog results
  (see http://gerrit.rockbox.org/r/#/c/1047/).
- Rewrite of configure (Android NDK) and device specific config.
- Rewrite of the Android NDK specific Makefile.

Misc

- All plugins/games/demos activated.
- Update tinyalsa to latest from https://github.com/tinyalsa/tinyalsa.

Includes

- http://gerrit.rockbox.org/r/#/c/993/
- http://gerrit.rockbox.org/r/#/c/1010/
- http://gerrit.rockbox.org/r/#/c/1035/

Does not include http://gerrit.rockbox.org/r/#/c/1007/ due to new backlight
interface and new option for hold switch, touchscreen, physical button
interaction.

Rockbox needs the iBasso DX50/DX90 loader for startup, see
http://gerrit.rockbox.org/r/#/c/1099/

The loader expects Rockbox to be installed in /mnt/sdcard/.rockbox/. If
/mnt/sdcard/ is accessed as USB mass storage device, Rockbox will exit
gracefully and the loader will restart Rockbox on USB disconnect.

Tested on iBasso DX50.
Compiled (not tested) for iBasso DX90.
Compiled (not tested) for PLATFORM_ANDROID.

Get rid of stupid _backlight_* function names

2015-01-12T10:09:27+00:00

_remote_backlight_* and _buttonlight_* are cleaned as well

Change-Id: I73653752831bbe170c26ba95d3bc04c2e3a5cf30

All kernel objects in code shared amongs targets (core, plugins, codecs) should be declared SHAREDBSS_ATTR as any core could potentially touch them even though they seem only to involve threads on one core. The exception is target code for particular CPUs where proper allocation is fixed. playlist.c was a little odd too-- use one mutex for the current playlist and a separate one for created playlists (still pondering the necessity of more than one).

Try to get some control over #ifdef hell in usb.c by refactoring and inline function use. SYS_USB_DISCONNECTED_ACK hasn't been doing anything useful for the USB thread; remove it. USB thread simply ignores that value. Observe only valid usb_state transitions.

Fix #ifdef in backlight.c from previous commit

Various minor cleanups

I shouldn't have touched backlight.c at all :\ Also fix the yellow in peakmeter.c

git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27022 a1c6a512-1295-4272-9138-f99709370657

Fix yellows and reds (one was a type, the other was rather incorrect before already)

Rockbox as an application: Replace many occurences of #ifdef SIMULATOR with #if (CONFIG_PLATFORM & PLATFORM_HOSTED) (or equivalently).

2010-06-21T16:53:00+00:00

The simulator defines PLATFORM_HOSTED, as RaaA will do (RaaA will not define SIMULATOR).
The new define is to (de-)select code to compile on hosted platforms generally.

Should be no functional change to targets or the simulator.

Fix FS#10362 (flickering backlight when removing hold) by preventing multiple SYS_TIMEOUT events being posted the backlight thread.
