Pierre-Louis Bossart 1fefc14402 alsa-info: add ACPI device status ... BIOS vendors typically reuse the same definitions between different platforms and expose the relevant hardware by changing the value of the _STA method. For example on the Asus T100HA, there are 3 HID values for audio codecs in the DSDT table but two have a zero status and will be ignored by the ACPI subsystem. $ more /sys/bus/acpi/devices/10EC*/status :::::::::::::: /sys/bus/acpi/devices/10EC3270:00/status :::::::::::::: 15 :::::::::::::: /sys/bus/acpi/devices/10EC5640:00/status :::::::::::::: 0 :::::::::::::: /sys/bus/acpi/devices/10EC5648:00/status :::::::::::::: 0 This information is very useful to figure out which HIDs/quirks need to be supported. Add log to alsa-info.sh to only expose non-zero results of the ACPI _STA method, e.g. !!ACPI Device Status Information !!--------------- /sys/bus/acpi/devices/10EC3270:00/status 15 Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>		2017-01-10 09:09:57 +01:00
