* Bump internal mix buffer size by 4x, to 1K frames (matching ALSA period)
* Handle an underrun that occurs when filling the audio buffer
* Log underruns and make them available in the debug info
Change-Id: I28d56dd35d88851fa167ad92368a5882937a758f
* pcm_get_bytes_remaining()
* pcm_calculate_peaks()
* pcm_get_peak_buffer()
Nothing in-tree uses these at all (except for the lua plugin wrapper)

Also audiohw driver to specific device name, rewrite alsa controls code to
cache more data, thus making the code easier and use less stack. Avoid using
short/long in pcm alsa code since it's the wrong size on 64-bit (simulator
for example)

Nothing in the core has used it for some time. It's exported to the
plugin API but the last plugins to use it were switched to the mixer API
back in 2011.
This allows us to get rid of pcm_play_dma_pause() from all audio drivers
Change-Id: Ic3fa02592316f84963e41d792d1cabb436d1ff6b
* Get rid of non-async (ie tick task) mode due to inherent brokenness
* Get rid of nonblock mode; we never write if buffers aren't sufficient
* Move driver init into pcm_open() instead of pcm_init()
* Much better underrun handling
* Better error handling in some situations
* Add in recording functionality
* Use smaller audio buffers to avoid glitching
* Don't start audio buffer with silence
* Allow device name to be overridden by target
Recording portions based on work done by Lorenzo Miori in g#633
Change-Id: I0197bdc1749c28109eb79def1e6a3e1d62d8cef3
* Allow output device name to be specified
* Set hw/swparams prior to actual playback start, not at init
* If told to open a new device, cleanly close down old one.
Change-Id: Ib97310ec23588136c031466ee9c22312ab0f9f5a
* Track mute state, only call hw if actual change is needed
* Don't unmute in audiohw_postinit()
* sample rate tracking fixes
* erosq: Don't start up muted
Change-Id: I004f787a4b7ea73c16b6ec9818ec29a12c89f46b
* If AUDIOHW_MUTE_ON_PAUSE, no meaningful change
* Unconditionally unmute on playback start
* xduoox3ii: Mute on sample rate change
* rocker/xduoo: Stay muted after startup
This avoids the nasty "pop" on startup, without doing
the full mute-on-pause stuff that causes unacceptable
dropouts on the X3ii.

Unsure why this is happening, but now we detect and recover errors at
startup.
Also clean up the mismash of printf(), DEBUGF(), etc in favor of panicf() for the really serious stuff and logf() for everything else.
Change-Id: I9aaa620d55d556645c9a6d108541b987983b32a8
* xduoo x3ii/x20: Better line out support
* less granular volume settings (too many steps before)
* Better handling of swiching sample rates
* Log actual sample rate in debug menu

Additional integration [re]work by myself

Always compile in pcm_alsa_set_digital_volume, the linker will optimize it
away on targets that don't use it.

NOTES:
- bootloader makefile convert an extra font to be installed alongside the bootloader
since sysfont is way too small
- the toolsicon bitmap comes from the Oxygen iconset
- touchscreen driver is untested
TODO:
- implement audio routing driver (pcm is handled by pcm-alsa)
- fix playback: it crashes on illegal instruction in DEBUG builds
- find out why the browser starts at / instead of /contents
- implement radio support
- implement return to OF for usb handling
- calibrate battery curve (NB: of can report a battery level on a 0-5 scale but
probabl don't want to use that ?)
- implement simulator build (we need a nice image of the player)
- figure out if we can detect jack removal
POTENTIAL TODOS:
- try to build a usb serial gadget and gdbserver

Yeah, sizeof (void) here with GCC is 1. If something has a problem
with that, we'll set it straight.

Additional status callback is added to pcm_play/rec_data instead of
using a special function to set it. Status includes DMA error
reporting to the status callback. Playback and recording callback
become more alike except playback uses "const void **addr" (because
the data should not be altered) and recording uses "void **addr".
"const" is put in place throughout where appropriate.
Most changes are fairly trivial. One that should be checked in
particular because it isn't so much is telechips, if anyone cares to
bother. PP5002 is not so trivial either but that tested as working.

Signals are by default executed on the user stack, i.e. the stack of
the currently active thread. This has two problems:
1) The stack size of the current stack is likely insufficient (unless
using sigaltstack threads) because our stack sizes are normally
below MINSIGSTKSIZE which is needed to deliver a signal.
2) Some of our asm code does nasty tricks with the stack pointer. When a
signal comes in during this bad things can happen, e.g. random memory
being overwritten or simply a crash.
Using a well defined stack fixes this. This is comparable with the
separate irq stack on native targets.
This port is a hybrid native/RaaA port. It runs on a embedded linux system,
but is the only application. It therefore can implement lots of stuff that
native targets also implement, while leveraging the underlying linux kernel.
The port is quite advanced. User interface, audio playback, plugins work
mostly fine. Missing is e.g. power mangement and USB (see SamsungYPR0 wiki page).
Included in utils/ypr0tools are scripts and programs required to generate
a patched firmware. The patched firmware has the rootfs modified to load
Rockbox. It includes a early/safe USB mode.
This port needs a new toolchain, one that includes glibc headers and libraries.
rockboxdev.sh can generate it, but e.g. codesourcey and distro packages may
also work.
Most of the initial effort is done by Lorenzo Miori and others (on ABI),
including reverse engineering and patching of the original firmware,
initial drivers, and more. Big thanks to you.
