scroll_engine: Fix FS#12894: Text scrolling stops working after a few seconds/minutes

2014-01-12T20:29:55+00:00

Since commit 706b920 a timeout of TIMEOUT_BLOCK (-1) will cause
queue_event_w_tmo() block indefinitely (previously it behaved as
TIMEOUT_NOBLOCK).  scroll_process_message() can be called with negative
timeouts, with luck also -1.

To fix this convert all negative timeouts to TIMEOUT_NOBLOCK explicitely.

scroll_engine: Major rework to support pixel-based scrolling and scroll callbacks.

2013-12-14T22:11:31+00:00

Much of the scrolling work is moved from lcd-bitmap-common to lcd-scroll.c,
a small scroll callback routine remains. This callback can potentially be
overridden by more extensive scrollers.

The callback also gets fed with pixel-based scrolling information, which
finally removes the strict line-based nature of the scroll engine. Along with
this is the change from scroll_stop_viewport_line() to scroll_stop_viewport_rect()
which works on a pixel-based rectangle instead of lines.

The ultimate goal is to move most of the scroll work to apps, which can
much better decide which line decorations to apply etc. This work is laying
the ground work.

scroll_engine: Split out common main and remote lcd functions.

2013-12-14T22:11:30+00:00

Uses a similar technique as lcd_*.c files of #including a common .c file, so
that a unified implementation can be reused for both displays.

scroll_engine: Rename scroll_stop* functions to be more consistent with the lcd api.

Commit FS#12454 - Faster line scroll speed by Martin Sagmuller.

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).

Introduce NORETURN_ATTR wrapper for attribute((noreturn)), using this and a bit further cleanup in main gets rid of a warning when compiling for android.

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.
