When detecting invalid value in 'dbs' field of CIP header or packet discontinuity, current implementation reports the status by err_info(). In most cases this state is caused by model-specific issue due to vendor's customization and should be reported to developers. This commit use dev_err() instead of dev_info() for this purpose. In the cases, packet streaming is aborted, thus no message floading occurs. Signed-off-by:

In previous commit, error handling for incoming packet processing is outside of packetization. This is nice for reading the codes. This commit applies this idea for outgoing packet processing, too. Signed-off-by:

Takashi Sakamoto authored
Current implementation reuses the value of syt field in incoming packet to outgoing packet for full duplex timestamp synchronization, while the number of data blocks in outgoing packets refers to hard-coded table and the synchronization cannot be applied to non-blocking stream. This commit passes the number of data blocks from incoming packet processing to outgoing packet processing for the synchronization. For normal mode, isochronous callback handler is changed to generate the values of syt and data blocks. Signed-off-by:

In IEC 61883-6, the number of data blocks in a packet is limited up to the value of SYT_INTERVAL. Current implementation is compliant to the limitation, while it can cause buffer-over-run when the value of dbs field in received packet is illegally large. This commit adds a validator to detect such illegal packets to prevent the buffer-over-run. Actually, the buffer is aligned to the size of memory page, thus this issue hardly causes system errors due to the room to page alignment, as long as a few packets includes such jumbo payload; i.e. a packet to several received packets. Here, Behringer F-Control Audio 202 (based on OXFW 960) has a quirk to postpone transferring isochronous packet till finish handling any asynchronous packets. In this case, this model is lazy, transfers no packets according to several cycle-start packets. After finishing, this model pushes required data in next isochronous packet. As a result, the packet include more data blocks than IEC 61883-6 defines. To continue to support this model, this commit adds a new flag to extend the length of calculated payload. This flag allows the size of payload 5 times as large as IEC 61883-6 defines. As a result, packets from this model passed the validator successfully. Signed-off-by:

The file is moved to hda core and renamed to hdac_i915.c, so can be used by both legacy HDA driver and new Skylake audio driver. - Add snd_hdac_ prefix to the public APIs. - The i915 audio component is moved to core bus and dynamically allocated. - A static pointer hdac_acomp is used to help bind/unbind callbacks to get this component, because the sound card's private_data is used by the azx chip pointer, which is a legacy structure. It could be removed if private _data changes to some core structure which can be extended to find the bus. - snd_hdac_get_display_clk() is added to get the display core clock for HSW/BDW. - haswell_set_bclk() is moved to hda_intel.c because it needs to write the controller registers EM4/EM5, and only legacy HD-A needs it for HSW/BDW. - Move definition of HSW/BDW-specific registers EM4/EM5 to hda_register.h and rename them to HSW_EM4/HSW_EM5, because other HD-A controllers have different layout for the extended mode registers.

The CA0132 DSP loader leads to NULL deference since the recent transition to HDA core code, as it unconditionally accesses hdac_stream->substream->runtime. For DSP loading, the substream shouldn't be assigned. This patch addresses the NULL dereference above in addition to assure the substream is cleared while DSP loading.

This patch adds quirks detection to the Creative CA0132 codec, and the quirk for Alienware 15 (2015). Some quirks may need different pin configuration, so the relevant compile-time configuration has been removed. The pin configuration and related initialization verbs are generated at runtime instead, in ca0132_config() and ca0132_prepare_verbs(). Signed-off-by:

The HDMI codec on NVIDIA Tegra SoCs has a feature that doesn't exist on the MCP or GPU variants. The highest bit in the vendor-defined scratch registers can be used to trigger an interrupt in the HDMI codec, which is signalled to the HDMI driver. This can be used to pass information, such as the HDA format, to the HDMI driver so that it can reconfigure itself accordingly. While at it, change the name of the codec to Tegra124 since there are no other SoCs in the Tegra12x family. There isn't really a Tegra12x family. Signed-off-by:

The commit [c560a679: ALSA: core: Remove child proc file elements recursively] converted snd_card_proc_new() with the normal snd_info_*() call and removed snd_device chain for such info entries. However, it misses one point: the creation of the proc entry was managed by snd_device chain in the former code, and now it's also gone, which results in no proc files creation at all. Mea culpa. This patch makes snd_info_card_register() creating the all pending child proc entries in a shot. Also, since snd_card_register() might be called multiple times, this function is also changed to be callable multiple times. Along with the changes above, now the linked list of snd_info_entry is added at creation time instead of snd_info_register() for keeping eyes of pending info entries.

snd_info_free_entry() releases the all children nodes as well, but due to the wrong timing of releasing the link, the children nodes may be disconnected but left unreleased. This patch fixes it by moving the link free at the right position. Also it eases list_for_each_entry() without _safe option in snd_info_disconnect() because it no longer frees the children nodes there.
