REMOVED FROM ALL NATIVE BOOTLOADERS:
finish removing the text scrolling
pare down printf to a minimal subset (%c %s %l %d %u and %x(%p))
remove diacritic and rtl language support
SUCCESS! (ASSUMING IT WORKS -- UNESTED)
(Hardware control isn't wired into ALSA properly)
* Execute the correct OF player binary
* We don't have adb, so error out
* HOME_DIR is now either "/" or special "<HOME>"
* target-specific "home dir path" is defined solely by PIVOT_ROOT
* PIVOT_ROOT path is now defined in toplevel config files
* Make Samsung YP-R0/R1 and SONY_NWZ use PIVOT_ROOT too
* Do not prepend PIVOT_ROOT path if the path already has it!
* Do not play these games for __PCTOOL__ builds
The Q and K have a slightly different case, but the hardware under the
shell is completely identical.
These models are rebadged versions:
* Hifiwalker H2 (== Q)
* AGPTek H3 (== K)
* Surfans F20 (== K)
* Significant improvements in the shared Hiby-platform launcher/loader
* SD card can theoretically be hot-swapped now
* Support external USB mass storage!
* Some consolidation of Hiby-platform targets
* Some consolidation of plugin keymaps
* Keymaps need to be gone over properly
* Convert to HAVE_SCROLLWHEEL?

This patch redoes the filesystem code from the FAT driver up to the
clipboard code in onplay.c.
Not every aspect of this is finished therefore it is still "WIP". I
don't wish to do too much at once (haha!). What is left to do is get
dircache back in the sim and find an implementation for the dircache
indicies in the tagcache and playlist code or do something else that
has the same benefit. Leaving these out for now does not make anything
unusable. All the basics are done.
Phone app code should probably get vetted (and app path handling
just plain rewritten as environment expansions); the SDL app and
Android run well.
Main things addressed:
1) Thread safety: There is none right now in the trunk code. Most of
what currently works is luck when multiple threads are involved or
multiple descriptors to the same file are open.
2) POSIX compliance: Many of the functions behave nothing like their
counterparts on a host system. This leads to inconsistent code or very
different behavior from native to hosted. One huge offender was
rename(). Going point by point would fill a book.
3) Actual running RAM usage: Many targets will use less RAM and less
stack space (some more RAM because I upped the number of cache buffers
for large memory). There's very little memory lying fallow in rarely-used
areas (see 'Key core changes' below). Also, all targets may open the same
number of directory streams whereas before those with less than 8MB RAM
were limited to 8, not 12 implying those targets will save slightly
4) Performance: The test_disk plugin shows markedly improved performance,
particularly in the area of (uncached) directory scanning, due partly to
more optimal directory reading and to a better sector cache algorithm.
Uncached times tend to be better while there is a bit of a slowdown in
dircache due to it being a bit heavier of an implementation. It's not
noticeable by a human as far as I can say.
Key core changes:
1) Files and directories share core code and data structures.
2) The filesystem code knows which descriptors refer to same file.
This ensures that changes from one stream are appropriately reflected
in every open descriptor for that file (fileobj_mgr.c).
3) File and directory cache buffers are borrowed from the main sector
cache. This means that when they are not in use by a file, they are not
wasted, but used for the cache. Most of the time, only a few of them
are needed. It also means that adding more file and directory handles
is less expensive. All one must do in ensure a large enough cache to
4) Relative path components are supported and the namespace is unified.
It does not support full relative paths to an implied current directory;
what is does support is use of "." and "..". Adding the former would
not be very difficult. The namespace is unified in the sense that
volumes may be specified several times along with relative parts, e.g.:
"/<0>/foo/../../<1>/bar" :<=> "/<1>/bar".
5) Stack usage is down due to sharing of data, static allocation and
less duplication of strings on the stack. This requires more
serialization than I would like but since the number of threads is
limited to a low number, the tradoff in favor of the stack seems
6) Separates and heirarchicalizes (sic) the SIM and APP filesystem
code. SIM path and volume handling is just like the target. Some
aspects of the APP file code get more straightforward (e.g. no path
hashing is needed).
Deserves its own section. Dircache is new but pays homage to the old.
The old one was not compatible and so it, since it got redone, does
all the stuff it always should have done such as:
1) It may be update and used at any time during the build process.
No longer has one to wait for it to finish building to do basic file
management (create, remove, rename, etc.).
2) It does not need to be either fully scanned or completely disabled;
it can be incomplete (i.e. overfilled, missing paths), still be
of benefit and be correct.
3) Handles mounting and dismounting of individual volumes which means
a full rebuild is not needed just because you pop a new SD card in the
slot. Now, because it reuses its freed entry data, may rebuild only
4) Much more fundamental to the file code. When it is built, it is
the keeper of the master file list whether enabled or not ("disabled"
is just a state of the cache). Its must always to ready to be started
and bind all streams opened prior to being enabled.
5) Maintains any short filenames in OEM format which means that it does
not need to be rebuilt when changing the default codepage.
1) Update any other code that would otherwise not work such as the
hotswap mounting code in various card drivers.
2) File management: Clipboard needed updating because of the behavioral
changes. Still needs a little more work on some finer points.
3) Remove now-obsolete functionality such as the mutex's "no preempt"
flag (which was only for the prior FAT driver).
4) struct dirinfo uses time_t rather than raw FAT directory entry
time fields. I plan to follow up on genericizing everything there
(i.e. no FAT attributes).
5) unicode.c needed some redoing so that the file code does not try
try to load codepages during a scan, which is actually a problem with
the current code. The default codepage, if any is required, is now
kept in RAM separarately (bufalloced) from codepages specified to
iso_decode() (which must not be bufalloced because the conversion
may be done by playback threads).
Brings with it some additional reusable core code:
1) Revised file functions: Reusable code that does things such as
safe path concatenation and parsing without buffer limitations or
data duplication. Variants that copy or alter the input path may be
based off these.
1) Put dircache functionality back in the sim. Treating it internally
as a different kind of file system seems the best approach at this
2) Restore use of dircache indexes in the playlist and database or
something effectively the same. Since the cache doesn't have to be
complete in order to be used, not getting a hit on the cache doesn't
unambiguously say if the path exists or not.

Although both players basically have the same keys, the
differences in the layout is rather big, so I think both
deserve their own keymaps.
(On the yh820 the FFWD/PLAY/REW buttons are located above the
direction keys, on the yh920 at the side of the player.
Furthermore the yh920/925 has a REC switch, whereas
yh820 has a push button.)

After placing the firmware.mi4 file in the root dir of the player in UMS mode of
the OF, Sansa should do stupid blinking with the backlight and buttonlight
alternately. Recovering from this state is possible through the recovery mode
(see Wiki), by putting an original copy of the firmware.mi4.
On the ZEN, the LCD is fed continuously by the DMA and this refresh needs to
be stop when the bootloader gives control to the firmware, otherwise the DMA
will source data from invalid region and it might even lock-up if the new
code touches the memory setup. Work around this by properly stopping the LCD
driver: the bootloader assumes that if the target defines HAVE_LCD_ENABLE
in bootloader build (which is unusual) then it needs to stop the LCD. Since
stopping the LCD could produce funny screens, power down backlight
which is expected to power down the LCD too, giving a nice black screen
instead of some random pixels.
