[alsa-devel] Query about code organization for kernel driver.
by Anksh Agarwal 25 May '10

25 May '10

Hi Everyone, I am currently working on a custom ARM based board and have succeeded in running alsa on my target. In this reference I have some basic queries and would be great if someone could give me pointers.This would help me in rorganizing the code as per acceptance from the group. since we planning to support a list of devices I wanted to keep the interface independent of playback/record session.this helps in switching to different devices in middle of playback. At any point a single device would be enabled. So i have another driver snd_device.c which uses sysfs interface to get device index or name to enable/disable device. The reason for this was that we could reuse a lot of code from the alsa-plugin(maemo). But then will it be right to put the device enable/disable code under sound/soc/xxxx/snd_device.c path, or can we split and place it seperately under sound/driver/xxxx/snd_device.c or any other suggested directory? i am not aware how to split the audio path enable/disable code from the soc driver and which would be ideal directory to place them, since there is hardly any interaction between playback and device enable/disable routines? I think the device enable/disable code outside sound/ directory wont be a good idea as its to be specifically used by alsa playback/record only. please suggest as this would help me a lot. Also let me know if any more info would help to get to a better conclusion. Really appreciate all the help. Thanks, Anksh

[alsa-devel] [PATCH] ASoC: Update Freescale i.MX SSI driver
by Stuart Longland 24 May '10

24 May '10

Hi all, Attached is a patch that corrects the i.MX SSI driver so that it compiles against the latest ASoC tree. I'm able to compile the driver with this patch, but haven't done any testing beyond this point... the update is quite naïve, based on changes I had seen to other drivers. I hope to give it a try on Monday, but in the meantime, here's the patch for others to try. -- Stuart Longland (aka Redhatter, VK4MSL) .'''. Gentoo Linux/MIPS Cobalt and Docs Developer '.'` : . . . . . . . . . . . . . . . . . . . . . . .'.' http://dev.gentoo.org/~redhatter :.' I haven't lost my mind... ...it's backed up on a tape somewhere.
