No targets are enabled, but the hosted Hiby-based targets could have this
feature enabled if they weren't so buggy:
* No generic way to determine wakeup reason under Linux
* No generic way to be asynchronously notified if the alarm is
triggered when we're already awake
* Shutting down may clobber RTC wakeup (driver/etc dependent)
* Rocker's kernel's RTC driver has some 24h clock and timezone-related
issues.
So, the infrastructure is arguably useful, but the only applicable
hardware I have is pathologically brain-dead.

Allow user to select cpu undervolt
There have been quite a few issues across the SANSA AMS line related
to CPU undervolting while most players show greatly increased runtime
some crash.
Rather than constanly upping the voltage we now have a
setting with a safe value for all players and the option for lower voltages
I plan to add a few other options here later such as disk
timings and maybe some other clocks/experimental settings
Added: Disk Low speed option for AS3525v2 devices cuts
frequency to 12 MHz from 24 MHz
Added: Disk Low speed option for AS3525v1 devices cuts
frequency to 15.5 MHz from 31 MHz
Added: I2c Low Speed AS3525 devices, should be bigger improvement for v1 devices
Fixed: Debug menu for AS3525v2 No SDSLOT frequency,
Showed IDE freq though it is unused
Added: DBOP and SSP underclocking affects display on v1/v2 respectively
Fixed: debug menu now has SSP frequency, and SSP_CPSR
Update: made settings menu more generic
Update: cleaned up code
Added: Clip v1 & Fuze v1 didn't have HAVE_ADJUSTABLE_CPU_VOLTAGE.
not sure why but, waiting on testing to confirm
Added: C200v2 and E200v2 devices and HAVE_ADJUSTABLE_CPU_VOLTAGE.
Fixed: v1 devices don't like display timing set lower (dbop)
v1 devices don't have a divider set for ssp (causes divide by 0)
Fixed: ClipZip display lags with Max SSP divider changed from 0xFE to 0x32
Fixed: v1 devices didn't work properly with highspeed sd cards
Added code from http://gerrit.rockbox.org/r/#/c/1704/
Added powersave and IDE interface enable/disable
Added: V2 devices now have powersave enabled on sd interface
Update: cleaned up code, lang defines, added manual entries
Update ssp clock mechanism added calculated ssp divider to clipzip
Update turn display clock off when clip+ turns off display
Fixed: clipzip wrong register for SSP clock

Adds the ability to load firmware from other drives on MULTIVOLUME targets
Mihail Zenkov <mihail.zenkov@gmail.com> had posted a hard coded patch
to allow this on several Sansa players, I made it more universal
Redirect file rockbox_main.<name> should placed in root of
drive you would like to be main, if this file empty or there a single
slash '/' firmware will be loaded from /.rockbox in root of this drive
If instead a /<*DIRECTORY*> is supplied in rockbox_main.<name> then
firmware will be loaded from /<dir>/.rockbox/
NOTES*
The directory can have multiple levels however..
leading slash MUST be included
trailing slash can be omitted
(eg. /test/.rockbox would be simply '/test' in the redirect file)
Redirect file will not work on internal drive (whatever is default boot drive)
Volume with the highest index containing redirect file will be loaded
first.
Firmware file is checked for boot data region, if missing, firmware
image will not be loaded.
On failure or if no redirect file is found load will fallback to
internal drive
Currently only Sansa Fuze+, Sansa Clip+,
Sansa Clip Zip, Sansa Fuzev2, and Sansa Fuzev1 are implemented.
Players (with HAVE_MULTIVOLUME)
will need #define HAVE_BOOTDATA and #define BOOT_REDIR "rockbox_main.<name>"
added to their config file
boot_data is implemented in crt0.s file (See g#1552)
ARM and IMX233 have aleady been implemented
Once these conditions are met <HAVE_MULTIBOOT> will be defined by config.h
Partitions on the drives are able to have a redirect as
well.

* Remove unused bits like the radio event and simplify basic
radio interface. It can be more self-contained with rds.h only
required by radio and tuner code.
* Add post-processing to text a-la Silicon Labs AN243. The chip's
error correction can only do so much; additional checks are highly
recommended. Simply testing for two identical messages in a row
is extremely effective and I've never seen corrupted text since
doing that, even with mediocre reception.
Groups segments must arrive in order, not randomly; logic change
only accepts them in order, starting at 0.
Time readout was made a bit better but really we'd need to use
verbose mode and ensure that no errors were seen during receiving
of time and more checks would be need to have a stable PI. The
text is the important bit anyway.
* Time out of stale text.
* Text is no longer updated until a complete group has been
received, as is specified in the standard. Perhaps go back to
scrolling text lines in the radio screen?
* Add proper character conversion to UTF-8. Only the default G0
table for the moment. The other two could be added in.
* Add variants "RDS_CFG_PROCESS" and "RDS_CFG_PUSH" to allow
the option for processed RDS data to be pushed to the driver and
still do proper post-processing (only text conversion for now for
the latter).

especially in USB mode.
2) Automatically reboot to updater when the user drop firmware.sb at the root
of the drive (currently, the user needs to do that in OF USB mode)

Some people reported strange charging times and
strange battery life.
Charging by OF: 25 hours; RB: 18 hours
It has been found that there are at least two issues here:
1) the way of getting battery charging status wasn't
really accurate. This attempts to fix that issue.
This patch also simplifies some code (opening a
device is no more needed, for example).
To technically explain, battery charging implies first a constant
current mode (where the voltage increases) and then a constant
voltage mode (where, obviously, the voltage reads more or less
the same). The old way the End Of Charge was detected was based solely
on the voltage, while now it is based on chip's EOC interrupt,
which should be more accurate.
2) OF explicitly sets a constant current 350 mA, while we usually had
55 mA (by as3543 default).
This wasn't discovered before since there is a caching problem
("an accurate guess") in the Samsung power mgmt Linux module,
thus its debugging dumper wasn't really working, reporting a 55 mA current.
Strangely this option should have been set by the bootloader
but apparently it does not.
Some testing is still needed, but I confirm that with this patch
I could run a benchmark for 25 hours (vs. 18 hours), by charging
within Rockbox of course.

The port to for this two targets has been entirely developped by Ilia Sergachev (alias Il or xzcc). His source
can be found at https://bitbucket.org/isergachev/rockbox . The few necesary modifications for the DX90 port
was done by headwhacker form head-fi.org. Unfortunately i could not try out the final state of the DX90 port.
The port is hosted on android (without java) as standalone app. The official Firmware is required to run this port.
Ilia did modify the source files for the "android" target in the rockbox source to make the DX port work. The work I did
was to separate the code for DX50 (&DX90) from the android target.
On this Target Ilia used source from tinyalsa from AOSP. I did not touch that part of the code because I do not understand it.
What else I changed from Ilias sources besides the separation from the target "android":
* removed a dirty hack to keep backlight off
* changed value battery meter to voltage battery meter
* made all plugins compile (named target as "standalone") and added keymaps
* i added the graphics for the manual but did not do anything else for the manual yet
* minor optimizations
known bugs:
* timers are slowed donw when playback is active (tinyalsa related?)
* some minor bugs
Things to do:
* The main prolem will be how to install the app correctly. A guy called DOC2008 added a CWM (by androtab.info) to the
official firmware and Ilia made a CWM installation script and a dualboot selector (rbutils/ibassoboot, build with
ndk-build). We will have to find a way to install rockbox in a proper way without breaking any copyrights.
Maybe ADB is an option but it is not enable with OF by default. Patching the OF is probably the way to go.
* All the wiki and manual
to build:
needed: android ndk installed, android sdk installed with additional build-tools 19.1.0 installed
./tools/configure
select iBasso DX50 or iBasso DX90
make -j apk
the content of rockbox.zip/.rockbox needs to be copied to /system/rockbox/app_rockbox/rockbox/ (rockbox app not needed)
the content of libs/armeabi to /system/rockbox/lib/ (rockbox app needed)
The boot selector is needed as /system/bin/MangoPlayer and the iBasso app as /system/bin/MangoPlayer_original. There
is also the "vold" file. The one from OF does not work with DX50 rockbox (DX90 works!?), the one from Ilia is necessary.
Until we have found a proper way to install it, it can only be installed following the instructions of Ilia on his
bitbucket page, using the CWM-OF and his installation script package.

To stop erroneous button presses, allow users to add a deadzone between
the button via the Settings > General > System menu > Touch Dead Zone.
The configuration was chosen this way: the touchpad has the same DPI
in both direction so the setting applies the same on both the X and Y
axis. The setting ranges from 0 to 100 and is internally multiplied by 2
giving a maximum deadzone of 2*100 = 200 around each button, which
account for 400 total (once around each button), effectively reducing
each virtual button from 1000x600 to 600x200 when using the maximum value.

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
less.
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
borrow from.
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
reasonable.
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).
Dircache:
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
that volume.
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.
Miscellaneous Compatibility:
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.
To do:
1) Put dircache functionality back in the sim. Treating it internally
as a different kind of file system seems the best approach at this
time.
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.

The "percent_to_volt_charge" values are quite arbitrary
and may need some more tweaking.
