2010-09-17Allow e200 to compile without HAVE_RECORDINGFrank Gevaerts
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28104 a1c6a512-1295-4272-9138-f99709370657
2010-06-26Should clear up rest of red. Add a required #define in the config for c200. ↵Michael Sevakis
Fix up some preprocessing directives. Hope it's all taken care of now. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27141 a1c6a512-1295-4272-9138-f99709370657
2010-06-26e200v1/c200v1: Implement limited samplerate switching. Rates 24kHz and below ↵Michael Sevakis
are being a bear as far as minor crackling at higher amplitude-- leave them out for the time being since no solution is currently evident. 48, 44, 32 (rec rates 24, 22, 16) seem perfectly fine. I'm betting c200 is ok to include because it uses the same setup as e200. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27139 a1c6a512-1295-4272-9138-f99709370657
2010-05-24Make PCM->driver interface about as simple as it will get. Registered ↵Michael Sevakis
callback, zero data, alignment and stops are handled entirely inside pcm.c; driver merely calls fixed pcm.c callback. Remove pcm_record_more and do it just like playback; the original reason behind it isn't very practical in general. Everything checks out on supported targets. There wer some compat changes I can't check out on many unsupoorted but if there's a problem it will be a minor oops. Plugins become incompatible due to recording tweak-- full update. Sorted API. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26253 a1c6a512-1295-4272-9138-f99709370657
2010-05-13Trim down peak calculation a bit.Michael Sevakis
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25978 a1c6a512-1295-4272-9138-f99709370657
2010-05-12PCM bottom layer simplification. pcm_rec_peak_addr variable no longer has to ↵Michael Sevakis
be handled there. Driver can just return current pointer for recording peaks. A new define, HAVE_PCM_REC_DMA_ADDRESS, specifies that physical addresses are being used for recording and translation is needed before starting a new block. The drivers need not worry about aligning start and size nor should care if either will be zero. All this will be checked in the logical layer first. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25970 a1c6a512-1295-4272-9138-f99709370657
2010-04-27Remove pcm_mute() which has been unused since r19308Rafaël Carré
Remove audiohw_mute from header as well, and make this function static to each driver (commented out when it was unused) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25733 a1c6a512-1295-4272-9138-f99709370657
2010-02-10New plugin: FFT, A frequency analyzer pluginFrank Gevaerts
There is some more work needed: - Keymaps are definitely not perfect, touchscreen targets are disabled due to no keymap - There is no manual yet Author: Delyan Kratunov Flyspray: FS#10065 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24587 a1c6a512-1295-4272-9138-f99709370657
2009-10-22Code cleanup in dsp.c and misc.c, some commentsJeffrey Goode
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@23314 a1c6a512-1295-4272-9138-f99709370657
2009-02-08Gigabeat S: Implement an SDMA API and use it in the PCM driver. Some other ↵Michael Sevakis
miscellaneous adjustments to recording and PCM buffer to accomodate use of physical addresses and cache coherency. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19949 a1c6a512-1295-4272-9138-f99709370657
2008-12-14Check that PCM is playing/recording *after* getting the current position ↵Michael Sevakis
from the hardware layer. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19435 a1c6a512-1295-4272-9138-f99709370657
2008-12-13Keyclick fixup take two. It is only 88 samples (2msec) long so keep a small ↵Michael Sevakis
static buffer around for beeps less than or equal to keyclick duration. This way it operates no matter the buffer state and still won't interfere with alternate PCM operations like recording or plugin playback. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19415 a1c6a512-1295-4272-9138-f99709370657
2008-12-12Get rid of some pcm_apply_settings cruft at the low level I somehow missed. ↵Michael Sevakis
Move the ones in pcm.c around to better spots. Remove a variable from pcm-pnx0101.c that should no longer be there. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19402 a1c6a512-1295-4272-9138-f99709370657
2008-12-12Bring consistency to pcm implementation and samplerate handling. Less ↵Michael Sevakis
low-level duplication. A small test_sampr fix so it works on coldfire again. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19400 a1c6a512-1295-4272-9138-f99709370657

2008-06-28Updated our source code header to explicitly mention that we are GPL v2 orDaniel Stenberg
later. We still need to hunt down snippets used that are not. 1324 modified files... http://www.rockbox.org/mail/archive/rockbox-dev-archive-2008-06/0060.shtml git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17847 a1c6a512-1295-4272-9138-f99709370657
2008-04-06Enable nocache sections using the linker. PP5022/4 must use SW_CORELOCK now ↵Michael Sevakis
with shared variables in DRAM (it seems swp(b) is at least partially broken on all PP or I'm doing something very wrong here :\). For core-shared data use SHAREDBSS/DATA_ATTR. NOCACHEBSS/DATA_ATTR is available whether or not single core is forced for static peripheral-DMA buffer allocation without use of the UNCACHED_ADDR macro in code and is likely useful on a non-PP target with a data cache (although not actually enabled in config.h and the .lds's in this commit). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16981 a1c6a512-1295-4272-9138-f99709370657
2007-10-07Still on the post-big-commit policing. Correct a function call order. ↵Michael Sevakis
Comment a couple things. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15031 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
