Change Details

If a sound module is compiled in, the PCM_KLDSTRING() macro used to form the string passed to pcm_setstatus(), and later fetched by the SNDCTL_CARDINFO ioctl to populate the "hw_info" field of oss_card_info, will not contain any information about the module responsible for the related device(s). However, it doesn't hurt to provide that information even when the module is compiled in. Sponsored by: The FreeBSD Foundation MFC after: 2 weeks

PCM_KLDSTRING() adds the audio device's associated kernel module to the string passed to pcm_setstatus(), which is used by the SNDCTL_CARDINFO ioctl to populate the "hw_info" field of oss_card_info. However, because PCM_KLDSTRING() only works for modules not compiled in the kernel, this information is not always available. This patch gets rid of PCM_KLDSTRING() altogether as it doesn't hurt to include this information even for modules that are compiled in. While at it, the string format is slightly changed from "at <info> kld <module>" to "at <module>/<info>" to make the output cleaner. Sponsored by: The FreeBSD Foundation MFC after: 2 weeks
