ALSA: hda: Skip event processing for unregistered codecs

2022-07-15T14:26:50+00:00

When codec is unbound but not yet removed, in the eyes of snd_hdac_bus_process_unsol_events() it is still a valid target to delegate work to. Such behaviour may lead to use-after-free errors. Address by verifying if codec is actually registered. Signed-off-by: Cezary Rojewski Link: https://lore.kernel.org/r/20220706120230.427296-6-cezary.rojewski@intel.com Signed-off-by: Takashi Iwai

ALSA: hda: Add helper macros for DSP capable devices

2022-03-11T16:23:52+00:00

HDAudio drivers make heavy use of I/O operations. Declare a range of update, read and write helpers similar to those available for HDAudio legacy driver. These macros are used by AVS driver to improve code readability.

ALSA/ASoC: hda: move/rename snd_hdac_ext_stop_streams to hdac_stream.c

2021-12-25T08:11:09+00:00

snd_hdac_ext_stop_streams() has really nothing to do with the extension, it just loops over the bus streams. Move it to the hdac_stream layer and rename to remove the 'ext' prefix and add the precision that the chip will also be stopped.

ALSA: hda: add link_power op to hdac_bus_ops

2021-02-08T14:56:35+00:00

The extended HDA bus (hdac_ext) provides interfaces for more fine-grained control of individual links than what plain HDA provides for. Links can be powered off when they are not used and if all links are released, controller can shut down the command DMA. These interfaces are currently not used by common HDA codec drivers. When a HDA codec is runtime suspended, it calls snd_hdac_codec_link_down(), but there is no link to the HDA extended bus, and on controller side the links are shut down only when all codecs are suspended. This patch adds link_power() to hdac_bus ops. Controllers using the HDA extended core, can use this to plug in snd_hdac_ext_bus_link_power() to implement more fine-grained control of link power. No change is needed for plain HDA controllers nor to existing HDA codec drivers.

ALSA: hda: Add dma stop delay variable

2020-08-05T10:27:47+00:00

A variable dma_stop_delay is added as a new member in hdac_bus structure to avoid memory decode error incase DMA RUN bit is not disabled in the given timeout from snd_hdac_stream_sync function and followed by stream reset which results in memory decode error between reset set and clear operation.

ALSA: hda: add member to store ratio for stripe control

2020-05-04T09:51:23+00:00

Stripe control programming is governed by following formula, which is referenced from the HD Audio specification(Revision 1.0a). { ((num_channels * bits_per_sample) / number of SDOs) >= 8 } Currently above is implemented in snd_hdac_get_stream_stripe_ctl(). This patch introduces a structure member to store the default factor of '8'. If any HW wants to use a different value, this member can be easily updated.
