2012-03-03Revise the PCM callback system after adding multichannel audio.Michael Sevakis5-17/+17
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. Change-Id: I4928d69b3b3be7fb93e259f81635232df9bd1df2 Reviewed-on: Reviewed-by: Michael Sevakis <> Tested-by: Michael Sevakis <>
2012-02-19beep/mixer code: Code police a bit.Michael Sevakis1-0/+1
/firmware is in the #include path with makes #include "asm/beep.c" sufficient. Add a comment to generic beep code and make another express intent better. Change-Id: I587cd704478b894785927bdfe2e647e28614df62
2012-02-18Split CPU-optimized beep code into the firmware/asm tree.Michael Sevakis3-0/+132
For now due to current lack of an apps/asm, place the ASM/generic code in the firmware/asm directory. Additionally, make generic beep code more generic. Change-Id: I4a69b6ffcbb97d9e6dfde2209c5a118de19e5638

2012-02-05Make generic pcm-mixer.c more generic in the way it writes output.Michael Sevakis2-112/+15
Also remove unused firmmware/asm/generic directory. Change-Id: If1961f96f4292f00227a9b0148181152ac405e51
2012-02-04Generic find_first_set_bit can use __builtin_ctz instead of __builtin_ffsbootloader_clipv2_v5Michael Sevakis1-3/+4
The former gives 0-based indexes, which is what our implementation returns, making the "- 1" unnecessary. Change-Id: I172ab5e06695be62e4a18d4fd0415b8314f5dc26

over generic C ones to firmware. Example: for a file asm/foo.c, make will look for asm/arm/foo.[cS] and compile it if found. If not found it'll fall back to asm/foo.c. Also introduce new ARCH make variable. This is automatically detected by configure. It is distinct from CPU since CPU defines the dir used for the target tree (i.e. firmware/target/X, so it can be "hosted"). ARCH really has the target isa and can be x86 for sims/raaa too.

2012-01-22Create fimrware/asm directory for assembly optimized stuff.Thomas Martitz13-0/+997
This dir is suitable for stuff that doesn't fit the target tree, e.g. because it also builds on hosted or otherwise. It also has a generic subfolder for fallback C implementations so that not all archs need to provide asm files. SOURCES should only contain "foo.c" where foo.c includes the specific <arch>/foo.c files from the subdirs using the preprocessor. This way automatic selection of asm versions or generic C verion is possible. For the start, the thread support files are moved, since ASM threads can be used on hosted platforms as well. Since core_sleep() remains platform specific it's moved to the corresponding system.h headers. Change-Id: Iebff272f3407a6eaafeb7656ceb0ae9eca3f7cb9
