ATI/AMD codecs do not support all the standard HDA HDMI/DP functions, instead various vendor-specific verbs are provided. This commit addresses these missing functions: - standard channel mapping support - standard infoframe configuration support ATI/AMD provides their own verbs that allow the following: - setting CA for infoframe - setting down-mix information for infoframe - channel pair remapping - individual channel remapping (revision ID 3+, 0x100300+) The documentation for the verbs has now been released by AMD: http://www.x.org/docs/AMD/AMD_HDA_verbs_v2.pdf Add support for the ATI/AMD specific verbs and use them instead of the generic methods on ATI/AMD codecs. This allows multi-channel PCM audio to work. Channel remapping is restricted to pairwise mapping on codecs with revision ID 2 (0x100200 as reported by procfs codec#X) or lower. This means cards up to Radeon HD7670 as far as I know. This will not affect standard multi-channel modes since these codecs support automatic FC-LFE swapping for HDMI. ATI/AMD codecs do not advertise all of their supported rates, formats and channel counts, therefore that information is forced accordingly so that all HDMI 1.x PCM parameters are marked as supported. Support for multiple ports is also added to patch_atihdmi so that 0x1002aa01 codecs with multiple ports will work properly when switched back to that patch. v2: splitted ELD emulation to a separate patch, tlv fixes v3: adapted to the new hdmi_ops infrastructure, fixed rev3+ vendor id Signed-off-by:

Upcoming AMD multichannel support requires many customized operations (channel mapping, ELD, HBR) but can otherwise share most of its code with the generic patch. Add a local struct hdmi_ops containing customizable HDMI-specific callbacks and move the current code to those callbacks. Functionality is unaltered. Signed-off-by:

The drain and drain_notify callback were blocked by low level driver untill the draining was complete. Due to this being invoked with big fat mutex held, others ops like reading timestamp, calling pause, drop were blocked. So to fix this we add a new snd_compr_drain_notify() API. This would be required to be invoked by low level driver when drain or partial drain has been completed by the DSP. Thus we make the drain and partial_drain callback as non blocking and driver returns immediately after notifying DSP. The waiting is done while relasing the lock so that other ops can go ahead.

It turned out that we can't use gen_pool_*() functions on archs without CONFIG_GENERIC_ALLOCATOR (resulting in missing symbols), since linux/genalloc.h doesn't provide dummy functions for all. We'd be able to fix linux/genalloc.h size, but I take an easier path for now... Reported-by:

When HP laptops with mute and mic-record LEDs go to runtime suspend, these LEDs are turned on forcibly no matter whether GPIO pis are on or off. This strange behavior seems triggered by resetting the HD-audio bus link at azx_rutime_suspend(). So, just add a new hda_bus flag to avoid the link reset at runtime suspend and set it for these HP machines. Signed-off-by:

Now it's quite common that an SoC contains its on-chip internal RAM. By using this RAM space for DMA buffer during audio playback/record, we can shutdown the voltage for external RAM to save power. So add new DEV type with iram malloc()/free() and accordingly modify current default mmap() for the iram circumstance. Signed-off-by:

Add a flag to snd_fw_transaction() to allow it to abort when a bus reset happens. This removes most of the duplicated error handling loops that were required around calls to the low-level fw_run_transaction(). Also add a flag to suppress error messages; errors are expected when we attempt to clean up after the device was unplugged. Signed-off-by:

When aborting a PCM stream, the xrun is signaled only if the stream is running. When disconnecting a PCM stream, calling snd_card_disconnect() too early would change the stream into a non-running state and thus prevent the xrun from being noticed by user space. To prevent this, move the snd_card_disconnect() call after the xrun. Signed-off-by:
