PATCH 1/1 qemu: enable audio support

From: Zhai Edwin <[email protected]>

On qemux86, export ac97 & es1370 emulated device to guest, and enable host oss&alsa driver. So end user can get sound from qemux86 guest if the sound card driver installed.

[BUGID #488] got fixed.

Is there a reason to limit this to qemux86/x86_64? Or are you assuming they won't work on other platforms (I have vague memories of putting an actual es1370 card in a powerpc platform, a long long time ago...)? Or have you confirmed elsewhere it's not supported outside these platforms?
Thanks!

I presume that you tested the sound, if you send me the working .config (or better a config fragement), I'll update the base configs for the qemu* platforms to at least build and make the modules available.

Looks good BTW!

Aha. Maybe I misunderstood. Did you need to change our qemu target kernel configuration to hear the sound ? If not, then this is a host side configuration item and we don't need to change the BSP configuration at all to enable sound!

I have not tested other platforms, so only enable qemux86/x86_64. But enabling on other platform is easy: Just change the poky-qemu script.

Yes, I mean qemux86/x86_64 target kernel config, so that target kernel can use emulated sound card device to make some noise on host:)

I just noticed the bugs that were assigned to me for this, I'll update the bugzilla cases with the information on how to modify the configuration.

Quoted 4 lines

I know there is something tricky to change the qemu target config as some internal tools are used. Last time, I hacked to add one extra config file including all changed entries. But forget it now:(

Luckily it isn't all that tricky anymore. If you create any file with ".cfg" as the extension that contains a series of kernel configuration values and add it to the SRC_URI in the same manner as any patch/defconfig, you've done most of the work to modifying the kernel configuration. The contents of that .cfg file will be added to the end of the kernel configuration and applied to the kernel build.

Those changes can then be sent for merging into the kernel repository as default values for the BSP in question.

Quoted 2 lines

What's your suggestion for our kernel user to hack the config?

See above. Start with a .cfg file, and then when you are happy with the configuration changes, you can either modify the 'meta' branch directly or simply send the .cfg file to me in a pull request and I'll apply it to the meta branch and merge it into the repository as the default for the BSP in question.'

If you search the mailing list for email from TomZ about the intel BSPs, you'll have some good examples on how to modify the meta branch directly (if you are interested).

Let me know if you need more details and I'd be more than happy to help out here! In particular if the documentation in or kernel/BSP guides isn't sufficient to help here, we should definitely improve it.

Cheers,

Bruce

If not, then this is a host side
configuration item and we don't need to change the BSP configuration at all to enable sound!

Re: [PATCH 1/1] qemu: enable audio support

From: Zhai Edwin<[email protected]>
On qemux86, export ac97& es1370 emulated device to guest, and enable host oss&alsa driver. So end user can get sound from qemux86 guest if the sound card driver installed.
Is there a reason to limit this to qemux86/x86_64? Or are you assuming they won't work on other platforms (I have vague memories of putting an actual es1370 card in a powerpc platform, a long long time ago...)? Or have you confirmed elsewhere it's not supported outside these platforms?

I think this is a case of one step at a time. Getting sound working on any of the qemu platforms is a step forward and once we get things working (and merged) for that, we can think about others which might be trickier.

Cheers,

Richard
