ASoC: Intel: avs: Fix build error on arc, m68k and sparc

2022-05-30T14:08:33Z

On some platforms (i.e. arc, m68k and sparc) __fls returns an int (while on most platforms it returns an unsigned long). This triggers a format warning on these few platforms as the driver uses %ld to print a warning. So explicitly cast the return value to unsigned long to make the warning go away (and so fix allmodconfig build on the affected architectures).

ASoC: Intel: avs: APL-based platforms support

2022-05-17T10:58:08Z

Define handlers specific to cAVS 1.5+ platforms, that is, APL and similar platforms. These differ from SKL-alike ones in terms of AudioDSP firmware generation and thus the '+' suffix. Introduciton of IMR, removal of CLDMA, D0IX support and monolithic-ation of library/module code are most impactful but are not the only changes brought with this newer generation. Some generic and 1.5 operations are being re-used to reduce code size.

ASoC: Intel: avs: SKL-based platforms support

2022-05-17T10:58:07Z

Define handlers specific to cAVS 1.5 platforms, that is SKL, KBL, AML and all other variants based on this very version of AudioDSP architecture. Most are specific to SKL-alike platforms with only skl_log_buffer_offset() being exposed and used later by younger equivalents.

ASoC: Intel: avs: Power management

2022-05-17T10:58:06Z

To preserve power during sleep operations, handle suspend (S3), hibernation (S4) and runtime (RTD3) transitions. As flow for all of is shared, define common handlers to reduce code size.

ASoC: Intel: avs: PCI driver implementation

2022-05-17T10:58:04Z

HD-Audio bus is a PCI device. Add all functions necessary to probe such device along with its removal sequence. Behaviour implemented for all standard operations is similar to existing solutions: sound/pci/hda and sound/soc/intel/skylake.

ASoC: Intel: avs: Machine board registration

2022-05-17T10:58:03Z

AVS driver operates with granular audio card division in mind. Super-card approach (e.g.: I2S, DMIC and HDA DAIs combined) is deprecated in favour of individual cards - one per each device. This provides necessary dynamism, especially for configurations with number of codecs present and makes it easier to survive auxiliary devices failures - one card failing to probe does not prevent others from succeeding. All boards spawned by AVS are unregistered on ->remove(). This includes dummy codecs such as DMIC. As all machine boards found in sound/soc/intel/boards are irreversibly tied to 'super-card' approach, new boards are going to be introduced. This temporarily increases number of boards available under /intel directory until skylake-driver becomes deprecated and removed.

ASoC: Intel: avs: D0ix power state support

2022-05-17T10:58:00Z

Audio DSP device supports D0 substates in form of D0ix, allowing for preserving more power even when device is still considered active (D0). When entered, certain domains which are not being currently used become power gated. Entering and leaving D0ix is a complex process and differs between firmware generations. Conditions that disallow D0i3 and require immediate D0i0 transition include but may not be limited to: IPC traffic, firmware tracing and SRAM I/O. To make D0ix toggling sane, delay D0i3 transition and refresh the timer each time an IPC is requested.

ASoC: Intel: avs: Prepare for firmware tracing

2022-05-17T10:57:59Z

Firmware provides its own debug functionality. While coredump is one of these, traces are the main area of interest. kfifo is enlisted to cache log data that is being pumped to driver through SRAM. Separate DSP operations are declared as actual feature implementation differs between firmware generations. As log gathering involves usage of IPCs, add all necessary: ENABLE_LOGS and SYSTEM_TIME.
