[alsa-devel] [PATCH] ALSA: hda - unmute pin amplifier in infoframe setup for Haswell
From: Mengdong Lin mengdong.lin@intel.com
When Gfx driver reconnects a port and transcoder, the pin amplifier will be muted. To enable sound, the pin amp need to be unmuted.
This patch - moves pin amp unmuting from stream preparing to hdmi_setup_audio_infoframe(). So if port:transcoder reconnection happens during stream playback, the ELDV unsol event can stil trigger pin's amp unmuting when re-setting up audio info frame.
- remove reading pin amp status before unmuting for speed-up, since pin amp should always be unmuted.
- rename haswell_verify_pin_D0() to haswell_verify_pin_cvt_D0(), since the convertor power state is also fixed here.
- define is_haswell() to replace checking Haswell vendor ID everywhere.
This patch is mostly based on suggestion of David Henningsson.

Have no patches right now. Feel free to go forward.

Yeah, but we'll keep maintaining the driver code, so changing this would be trivial ;)
Though, it'd be cleaner to split this patch: one for defining and replacing with is_hawell() (or whatever), and another actually changes haswell_veriy_pin_D0().

Hi Takashi and David,
Thanks for your comments! I'll split the patch.
Broadwell has the same HW behavior as Haswell. Maybe in the future, is_haswell() can be renamed to is_haswell_plus(), 'plus' means including the successor processors. This is the naming convention used in our documents.
"is_haswell_or_broadwell_or_somethingwell_or_verywell()" really sounds like "is_everywhere", considering these specific fixings :-)
Thanks Mengdong
