Part three of main AVS driver series. This series was originally part of the initial series which was later divided [1] into smaller, easier-to-review chunks. Thus, many patches found here were already present on the list.
This series consists of code typical to many drivers - PCI driver operations, trace ability, PM operations - as well as PCM handlers for all standard audio interfaces, that is, HDA, I2S and DMIC are found here.
Series starts with updating firmware boot flow - libraries are no longer ignored. This change is dependent on already merged topology code [2] and because of that could not be part of the initial series [1].
PCM operations are split into four changes. First component operations alone i.e. operations which are usually agnostic towards path position (FE/BE). Then it continues with "generic" FE operations - there is no interface split here as from Intel ADSP point of view, FE, or HOST side as it's called in the specs, involves HD-Audio operations only. BE (also known as LINK) side on the other hand is divided into "non-HD-Audio" and HD-Audio part. The former represents transfer over DMIC and I2S interfaces both.
While patches implementing standard PCI driver operations along (again standard) HD-Audio initialization routines followed up by power management handlers are two major ones, series covers also other important subjects such as:
While patches implementing standard PCI driver operations along (again standard) HD-Audio initialization routines followed up by power management handlers are two major ones, series covers also other important subjects such as:
- event tracing - preparation for firmware tracing (debugability) - coredump (debugability) - recovery flow (attempt recovery after IPC timeout or exception) - D0ix (D0 device substate, complements standard power management)
Series is finalized by actual addition of supported platforms: SKL and APL-based. Platform-specific files are limited to firmware-specific bits, that is, bits that are specific to given firmware generation. Everything else is shared and is part of already upstream messaging code found in ipc.c, messages.c and messages.h files.
Changes in v2: - usage of avs_releast_last_firmware() dropped in error path for library loading procedure as suggested by Pierre - 'link_mask' usage replaced with 'i2s_link_mask' as requested by Pierre. Existing code addressed with new patch: "ASoC: Intel: avs: Replace link_mask usage with i2s_link_mask" - fixed possible race during recovery flow (->recovering flag is now atomic and tested in single location only). - dropped platform prefixes for basically all i2s board descriptors - 'ssp_test' renamed to 'i2s_test' to match naming convention of other boards - simplified PM implementation for current series, 'low_power' bits moved to future series - replaced SND_INTEL_DSP_DRIVER_SST with _AVS as suggested by Mark. Required changes to intel-dspcfg will be added in future series - number of typos across commit messages addressed
