ALSA: hda: Allow for compress stream to hdac_ext_stream assignment Currently only PCM streams can enlist hdac_stream for their data transfer. Add cstream field to hdac_ext_stream to expose possibility of compress stream assignment in place of PCM one. Limited to HOST-type only as there no other users on the horizon.

ALSA: hda: Revert "ALSA: hda: Allow setting preallocation again for x86" This reverts commit f8e4ae10de43 ("ALSA: hda: Allow setting preallocation again for x86"). The reverted commit itself is a revert of c31427d0d21e ("ALSA: hda: No preallocation on x86 platforms"). It was needed because HDA allowed very big allocations, up to 1GB per stream. However as previous commit in this series changes maximum allowed allocation per stream to 4MB, we can safely revert it back. On systems where there are a lot of FrontEnds, when CONFIG_SND_HDA_PREALLOC_SIZE != 0 ALSA core allocates memory for each FE, which may cause out of memory problems due to per card limit. Force config to 0 on X86, so memory will be allocated on as needed basis.

ALSA: hda: move Intel SoundWire ACPI scan to dedicated module The ACPI scan capabilities is called from the intel-dspconfig as well as the SOF/HDaudio drivers. This creates dependencies and randconfig issues when HDaudio and SOF/SoundWire are not all configured as modules. To simplify Kconfig dependencies between HDAudio, SoundWire, SOF and intel-dspconfig, move the ACPI scan helpers to a dedicated module. This follows the same idea as NHLT helpers which are already handled as a dedicated module. The only functional change is that the kernel parameter to filter links is now handled by a different module, but that was only provided for developers needing work-arounds for early BIOS releases.

ALSA: hda/i915 - fix list corruption with concurrent probes Current hdac_i915 uses a static completion instance to wait for i915 driver to complete the component bind. This design is not safe if multiple HDA controllers are active and communicating with different i915 instances, and can lead to list corruption and failed audio driver probe. Fix the design by moving completion mechanism to common acomp code and remove the related code from hdac_i915.

PM: runtime: Simplify pm_runtime_get_if_active() usage [ Upstream commit c0ef3df8dbaef51ee4cfd58a471adf2eaee6f6b3 ] There are two ways to opportunistically increment a device's runtime PM usage count, calling either pm_runtime_get_if_active() or pm_runtime_get_if_in_use(). The former has an argument to tell whether to ignore the usage count or not, and the latter simply calls the former with ign_usage_count set to false. The other users that want to ignore the usage_count will have to explicitly set that argument to true which is a bit cumbersome. To make this function more practical to use, remove the ign_usage_count argument from the function. The main implementation is in a static function called pm_runtime_get_conditional() and implementations of pm_runtime_get_if_active() and pm_runtime_get_if_in_use() are moved to runtime.c.

ALSA: hda: Use regcache_reg_cached() rather than open coding The HDA driver intentionally drops repeated writes to registers in some circumstances, beyond the suppression of noop writes that regmap does in regmap_update_bits(). It does this by checking if the register is cached before doing a regmap_update_bits(), now we have an API for querying this directly use it directly rather than trying a read in cache only mode making the code a little clearer.

ASoC: Intel: sst: Support LPE0F28 ACPI HID [ Upstream commit 6668610b4d8ce9a3ee3ed61a9471f62fb5f05bf9 ] Some old Bay Trail tablets which shipped with Android as factory OS have the SST/LPE audio engine described by an ACPI device with a HID (Hardware-ID) of LPE0F28 instead of 80860F28. Add support for this. Note this uses a new sst_res_info for just the LPE0F28 case because it has a different layout for the IO-mem ACPI resources then the 80860F28. An example of a tablet which needs this is the Vexia EDU ATLA 10 tablet, which has been distributed to schools in the Spanish Andalucía region.

tracing: ALSA: hda: Remove string manipulation out of the fast path The TRACE_EVENT() macro is broken up into various parts to be efficient. The TP_fast_assign() is just to record the event into the ring buffer, and is to be done as fast as possible as this occurs during the actual running of the code. The slower this is, the slower the code that is being traced becomes. The TP_printk() is processed when reading the tracing buffer. This is considered the slow path. Any processing that can be moved from the TP_fast_assign() to the TP_printk() should do so. For some reason, the entire string processing of the trace events hda_send_cmd, hda_get_response, and hda_unsol_event was moved from the TP_printk() into the TP_fast_assign(). On top of that, the __dynamic_array() was used with a fixed size of HDAC_MSG_MAX, which is useless as a dynamic_array as it will always allocate HDAC_MSG_MAX bytes on the ring buffer and even save that amount into the event (as it expects the size to be dynamic, which using a fixed size defeats that purpose). Instead, just save the necessary elements in the TP_fast_assign() and do the string manipulation in the slow path. The output should be the same.
