[alsa-devel] Gitcompile for Kernel 3.2?
by Brand, Mark (Mr) (Summerstrand Campus South) 13 Aug '12

13 Aug '12

Hi all, Having cloned alsa-driver and alsa-kmirror, my gitcompile and sudo make install-modules goes smoothly. However, the modules won't load. First errors in dmesg are: [ 24.415466] snd_hwdep: disagrees about version of symbol snd_info_register [ 24.415475] snd_hwdep: Unknown symbol snd_info_register (err -22) [ 24.415489] snd_hwdep: disagrees about version of symbol snd_info_create_module_entry [ 24.415495] snd_hwdep: Unknown symbol snd_info_create_module_entry (err -22) ... and so on. My initial assumption is that kmirror is specific to a 2.6 kernel, while I'm running 3.2, though some of what I've read seems to contradict this. I've tried foregoing kmirror for a full 3.2 kernel source, but that failed on gitcompile. I also tried with kmirror on a 2.6 kernel, but those modules also failed to load. I initially thought my problems stemmed from trying to do this against a lowlatency kernel, but I've subsequently had the same against vanilla Ubuntu kernels. Would someone kindly point me in the right direction? * Is it possible to compile and load a subset of alsa modules without having full kernel sources on hand? * If so, is this restricted to particular kernels (docs seem to suggest 2.6, 3.0 and 3.2 are supported)? * If not, is alsa-driver expected to compile against 3.2 sources as is (mine fails on some of the patching - presumably the make dep step)? * Does the alsa-driver.new.git merge address this, or is development expected to take place in a 2.6 environment? Sorry if any or all of this is incoherent (please help me to clarify), but any pointers would be greatly appreciated. What might be pertinent: Ubuntu 12.04 (kernels 3.2.0 and 2.6.38 tested), gcc 4.6.3, anything else? I am attempting to add device support for a multi-port MIDI interface. I managed to get a working prototype running a year ago, but had to shelve the project due to work pressures. I'd really love to get it back up and submitted. Kind regards, Mark Brand. ________________________________ NOTICE: Please note that this eMail, and the contents thereof, is subject to the standard NMMU eMail disclaimer which may be found at: http://www.nmmu.ac.za/disclaimer/email.htm

[alsa-devel] [PATCH 00/11] MFD/ASoC/Input: twl4030-audio submodule DT support
by Peter Ujfalusi 12 Aug '12

12 Aug '12

Hello, The following series adds DT support for the twl4030 audio submodule which provides audio codec and vibra functionality. The MFD core driver is probed via DT, it will create the needed child devices based on the provided information in the DT blob. Child drivers (vibra, ASoC codec) will parse the core's node if needed to get the needed parameters for their configuration. In the ASoC codec driver the hs_extmute callback (which was used to toggle a GPIO line) has been removed. The codec driver will receive the GPIO number (if it is needed on the platform) and also the level to disable the mute. If the series is OK (and no objections from the maintainers), it would be good if this can go via audio. Changed files are well contained within the twl4030-audio stack so I do not expect merge issues later. The series has been tested on BeagleBoard (with the McBSP DT series, and with the upcoming DT audio support for BeagleBoard).

Well, for cleanness, I think we should start rather from scratch: - The first patch to add a new hda_bus_ops for DSP transfer; it won't touch patch_ca0132.c but only the core part (hda_intel.c, hda_codec.[ch]) - Add the DSP transfer to patch_ca0132.c; at this point, just do DMA transfer but no new mixers etc won't be added - Add new features to patch_ca0132.c At the early development stage, the first two items can be a single patch. We can split to two when applied to the upstream. But, mixing all changes in a single patch is pretty bad. So the point is to concentrate only on DMA transfer stuff at first. Once after confirmed it's working, continue to the new DSP features. > We're also currently ascertaining the license information to go along with the > firmware binary release. Good.

[alsa-devel] [PATCH] ALSA : hda - bug fix on return value check when getting supported power states of a codec
by Lin, Mengdong 10 Aug '12

10 Aug '12

The return value of snd_hda_param_read() is -1 for an error, otherwise it's the supported power states of a codec. The supported power states is a 32-bit value. Bit 31 will be set to 1 if the codec supports EPSS, thus making "sup" negative. And the bit 28:5 is reserved as "0". So a negative value other than -1 shall be further checked. Please refer to High-Definition spec 7.3.4.12 "Supported Power States", thanks!

[alsa-devel] [PATCH 00/11] ARM/ASoC: OMAP McBSP device tree support
by Peter Ujfalusi 10 Aug '12

10 Aug '12

Hello, in order to be able to add DT support for the McBSP driver which is used on all OMAP platforms (OMAP1/2/3/4/5) I needed to make some cleanups to the stack: - Removing callbacks used by the driver for - clock re-parenting (code moved to sound driver) - FSR/CLKR mux configuration (from now on it need to be done at board level) This mux is board specific and depends on the wiring. - OMAP3 sidetone ICLK workaround has been reimplemented using the SYSCONFIG register's SIDLEMODE filed to prevent ICLK gating while ST is running. - Replaced the cpu_is_omap* checks with future proof check. - The FIFO was not enabled on OMAP2430 SoC It has been tested on BeagleBoard (with legacy and DT boot). The series changes McBSP related files mostly. It would be great if the whole series could go via audio tree (if the patches are OK and it is fine by Tony).
