Some notes: - Shall we show an empty file if the ELD content is not valid? Well it's not that simple. There could be partially populated ELD, and there may be malformed ELD provided by buggy drivers/monitors. So expose ELD as it is. - The ELD retrieval routines rely on the Intel HDA interface, others are/could be universal and independent ones. - How do we name the proc file? If there are going to be two HDMI pins per codec, then the current naming scheme (eld#) will fail. Luckily the user space dependencies should be minimal, so it would be trivial to do the rename if that happens. - The ELD proc file content is designed to be easy for scripts and human reading. Its lines all have the pattern: \t[\t]* where is a keyword in c language, while could be any contents, including white spaces. could also be a null value.

loaded via udev - snd-hda-codec HD-audio codec bus driver - snd-hda-codec-* Specific HD-audio codec drivers When built as modules, snd-hda-codec (that is invoked by snd-hda-intel) looks up the codec vendor ID and loads the corresponding codec module automatically via request_module(). When built in a kernel, each codec drivers are statically hooked up before probing the PCI. This patch adds appropriate EXPORT_SYMBOL_GPL()'s and the module information for each driver, and driver-linking codes between codec-bus and codec drivers. TODO: - Avoid EXPORT_SYMBOL*() when built-in kernel - Restore __devinit appropriately depending on the condition Signed-off-by: Takashi Iwai --- sound/pci/hda/Kconfig | 50 +++++++++++
