2008-05-03Another round of making local functions static and making sure that source ↵Bertrik Sikken
files are in sync with their header files. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17337 a1c6a512-1295-4272-9138-f99709370657
2008-03-26Do core interrupt masking in a less general fashion and save some ↵Michael Sevakis
instructions to decrease size and speed things up a little bit. Small fix to a few places where interrupts would get enabled again where they shouldn't have been (context switching calls when disabled). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16811 a1c6a512-1295-4272-9138-f99709370657

2008-03-14More iAudio M3 work. Target build compiles, but same problem regarding ↵Jens Arnold
plugins as the simulator. Boots to the menu, but it can't be used yet because only main & remote Play button work. USB works. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16660 a1c6a512-1295-4272-9138-f99709370657
2007-10-06Unify PCM interface just above the hardware driver level for all targets ↵Michael Sevakis
including the sims. Perform lockout of audio callback when changing states. Weird new playback or recording trouble? Check before and after this revision first though things seem quite sound. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15006 a1c6a512-1295-4272-9138-f99709370657

2007-06-08Straighten out some audio path APIs and misc. audio stuff. Having recording ↵Michael Sevakis
is not a prerequisite to having input/output source selection which is probably most useful when adding a audio input features like FM to a new port without forcing recording to be implemented first. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13599 a1c6a512-1295-4272-9138-f99709370657
2007-05-20Use bitmasks to define which inputs are available. Makes it easier to remove ↵Michael Sevakis
old assumptions of which are available. Inspired by e200 being unique in having FM Radio and Mic but no Line. Doesn't remove the assumption that Mic is available or that one of Mic and/or Line is available just to avoid excessive #ifdef'ing until needed. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13448 a1c6a512-1295-4272-9138-f99709370657
2007-05-19always reset the pcm_paused flag when stopping playback. fixes FS #7187Marcoen Hirschberg

2007-04-18H100 S/PDIF recording: Check and clear the correct interrupt bits when ↵Michael Sevakis
recording from digital in. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13198 a1c6a512-1295-4272-9138-f99709370657
2007-03-14x5/M5: Finally get rid of filter selection aberrations when switching to ↵Michael Sevakis
88.2kHz sampling rate which affected both the DAC and ADC. Turning off the DAC and ADC before changing the internal codec frequency seems to cure the remaining glitch of the filters not being correctly selected by the TLV320. Some FIFO reset changes that help keep it stable as well. Supporting 88.2KHz on iAudio has been a tricky ordeal. Also made sure to ok the HW tone controls on iRiver. :) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12757 a1c6a512-1295-4272-9138-f99709370657
2007-03-13H100 Series: Fix FS#6810 - Distortion on Bass/Treble usage. Coldfire PCM ↵Michael Sevakis
needed a refinement in the init sequence for the UDA1380 after audio init changes. Apparently it doesn't like its registers altered before the Coldfire I2S is properly initialized. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12752 a1c6a512-1295-4272-9138-f99709370657
2007-03-11Audio Init: Just can't stand that heirarchy. Add one level of abstraction. ↵Michael Sevakis
Might come in handy anyhow. Use sound.h instead of the conditional includes for audio hardware headers. If someone doesn't like that, yell at my evil twin. :) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12718 a1c6a512-1295-4272-9138-f99709370657
2007-03-11Reenable aynchronous audio init stage. Really just single stage with ↵Michael Sevakis
aynchronous enabling of outputs. Keeps audio_init last so prior init steps can use the audiobuffer in any desired way. Audio will be fully initialized by the time the UI is entered. Playback of voice or audio will be delayed properly until audio hardware is ready. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12714 a1c6a512-1295-4272-9138-f99709370657
2007-03-07Coldfire targets: Shuffle IRQ levels around to have all interaction between ↵Michael Sevakis
low level audio function calls and DMA be atomic. Make recording and playback independently startable and stoppable so one can be running and not interfere with the other. All tests I can do at the moment check out ok (play, record, play+record, FM radio on iRivers, S/PDIF on H120 (w/running optical on/off), and on-the-fly samplerate changes). Recording tested for well over an hour run and no problems. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12658 a1c6a512-1295-4272-9138-f99709370657
2007-03-05More catching up on old work. Refine audio interface setup on Coldfire. Stop ↵Michael Sevakis
the funky glitching on the iAudio stuff when starting recording esp. at 88.2kHz. (probably due to the bidi interface). iRivers don't seem to care what you do. TLV320 still seems to have a little trouble selecting it's filters correctly for 88.2kHz or it could be some odd phasing effect. Get rid of the horrible reset parameter in pcm_apply_settings as it can decide for itself. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12618 a1c6a512-1295-4272-9138-f99709370657
2007-03-05Bring up the M5 port to a working stage: Extended numerous explicit checks ↵Jens Arnold
for IAUDIO_X5 to also check for IAUDIO_M5, moved code around the target tree, added preliminary background for the sim. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12610 a1c6a512-1295-4272-9138-f99709370657

2006-12-17Coldfire: More efficient and compact peaking code. Hope the build doesn't ↵Michael Sevakis
whine about strange asm constraints. GCC's ok with it here. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11786 a1c6a512-1295-4272-9138-f99709370657
2006-12-12Coldfire: Put DMA1 priority back at level 7 as that seems to be the cause of ↵Michael Sevakis
the stopping during record. Make DMA1 start as it did previously. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11729 a1c6a512-1295-4272-9138-f99709370657

2006-12-06Small change to PCM recording API for low latency effects. Latency can be as ↵Michael Sevakis
low as 14 samples from input to output including the FIFOs (ColdFire) but 16 is more reasonable an expectation if only tranferring one sample per interrupt (\!). May convert PCM playback to use the same method as it can still be used in the old manner with some slight mods but has the potential to enable new features since it is more flexible. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11668 a1c6a512-1295-4272-9138-f99709370657
2006-11-29PCM: A few tiny changes. 1) Recording a) Flush all pending files if filename ↵Michael Sevakis
queue is full or else perpetual flushing of 1 will occur at low bitrates and short split times. b) #ifdef out currently unused bits and save little less than 1/2K 2) Cleanup some declarations. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11623 a1c6a512-1295-4272-9138-f99709370657
2006-11-23iRiver/iAudio: Added audio_set_recording gain and sound_default to plugin ↵Michael Sevakis
API. Simplified plugin recording by target/-ing some audio functions. UDA1380 records with WSPLL as a result. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11577 a1c6a512-1295-4272-9138-f99709370657
2006-11-22Audio bugfixes. Should wait for voice codec to reload before returning ↵Michael Sevakis
buffer when stealing voice. Certain variables that get or may get used during an IRQ should be declared 'volatile'. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11572 a1c6a512-1295-4272-9138-f99709370657
