[PATCH v2 00/13] ASoC: Intel: Catpt - Lynx and Wildcat point
Implement support for Lynxpoint and Wildcat Point AudioDSP. Catpt solution deprecates existing sound/soc/intel/haswell which is removed in the following series. This cover-letter is followed by 'Developer's deep dive' message schedding light on catpt's key concepts and areas addressed.
Due to high range of errors and desynchronization from recommendations set by Windows solution, re-write came as a lower-cost solution compared to refactoring /haswell/ with several series of patches.
Special thanks go to Marcin Barlik and Piotr Papierkowski for sharing their LPT/WPT AudioDSP architecture expertise as well as helping backtrack its historical background. My thanks go to Amadeusz Slawinski for reviews and improvements proposed on and off the internal list. Most of internal diff below is his contribution. Krzysztof Hejmowski helped me setup my own Xtensa environment and recompile LPT/WPT FW binary sources what sped up the development greatly.
This would not have been possible without help from these champions, especially considering how quickly the catpt was written: 2 weeks features, 3 weeks optimizations. Thank you.
Userspace-exposed members are compatible with what is exposed by deprecated solution as well as FW binary being re-used thus no harm is done. The only visible differences are: the newly added 'Loopback Mute' kcontrol and volume support extending to quad from stereo.
On top of fixing erros and design flows, catpt also adds module reload, dynamic SRAM memory allocation during PCM runtime and exposes missing userspace API: 'Loopback Mute' kcontrol, quad volume controls and sysfs fw-version entries. Event tracing is provided to easy solution debugging.
Following are not included in this update and are scheduled as later addition: - fw logging - module (library) support
Note: LPT power up/down sequences might get aligned with WPT once enough testing is done as capabilities are shared for both DSPs. Note #2: Both LPT and WPT power up/down sequences may get optimized in future updates as thanks to help from the Windows team, most of nuances behind why/what/when in regard to hw registers have been backtracked and reviewed again.

Changes in v2: - fixed SPDX formatting for all header files as well as pcm.c - fixed size used when memcping fs.c::fw_build_read as reported by Mark - renamed struct catpt_pdata to struct catpt_spec (cosmetic) - fixed erroneous patch in catpt_load_block: region if properly released - trace.h events for updating registers have been removed and usages replaced by dev_dbg (SRAMPGE/ LPCS)
- as requested by Andy, struct resource has replaced struct catpt_mbank and struct catpt_mregion. This change cascaded into:
- catpt_mbank_size and catpt_mregion_size replaced by resource_size - catpt_mregion_intersects replaced by resource_overlaps - all catpt_mbank_ and catpt_mregion_ handlers found in loader.c (_request, _reserve, _release, _extract, _split, _join) have been removed - __request_region and __release_region have been enlisted in their place - catpt_mregion_intersecting renamed to catpt_resource_overlapping - catpt_request_region helper has been provided to deal with -size based requests o haven't found direct replacements in resource.c/ ioport.h for both functions
- catpt_mbank_create and catpt_mbank_remove renamed to catpt_sram_init and catpt_sram_free respectively - catpt_sram_init now returns void instead of int and has been converted to simple initialized. This change ultimately cascaded into: o both SRAM banks initialization being moved to catpt_dev_init from catpt_acpi_probe (device.c) o catpt_dev::spec is now initialized first, with catpt_dev_init following it soon after o catpt_acpi_probe erroneous path has been simplified as SRAM banks no longer need to be freed
- catpt_sram_free now frees all resources via child -> sibling enumeration rather than region_list iteration - catpt_dsp_update_srampge and catpt_dsp_set_srampge now accept new argument: unsigned long mask. Caused by removal of catpt_mbank - mask is taken directly from catpt_dev::spec::d/iram_mask - trace.h events for catpt_mbank and catpt_mregion have been removed
Diff against last drop on internal list: - replaced spinlock with mutex for mregion allocation and release to address sleeping in atomic context warnings - fixed coredump fw_hash dumping - kcontrol values are now always stored regardless of stream of interest is running or not - kcontrol values are now applied after stream is prepared instead of ignoring what has been set by user initially - catpt_pdata instances have been renamed from hsw_ and bdw_ to lpt_ and wpt_ respectively - reordered Makefile .o(s) (cosmetic)

Sorry for the repeated mistake. Mark already did mention it. Fixed core.h, traces.h and messages.h but the register.h was omitted during the update.
Ack.
Implement dsp lifecycle functions such as core RESET and STALL, SRAM power control and LP clock selection. This also adds functions for handling transport over DW DMA controller.

Yes, for this update I've run tests for all bdw (wpt) devices -only. Thanks for catching this up!

For Lynxpoint and Wildcat Point solution, is it host's responsibility to allocate SRAM regions and ensure those already taken are not overwritten with other data until released. Blocks are transferred to SRAM - either IRAM or DRAM - via DW DMA controller. Once basefw is booted, ownership of DMA transfer is lost in favour of DSP.
Hosts reponsibilities don't end on initial block allocation and binary transfer. During Dx transitions host must store FW runtime context from DRAM before putting AudioDSP subsystem into lower power state. Said context gets flashed after D0 entry to bring DSP right where it was just before suspending.
Load and restore procedures are finalized with SRAM power gating and adequate clock level selection. This power gates unused EBBs and clock speed effectively reducing power consumption.

Implement IRQ handlers for immediate and delayed replies and notifications. Communication is synchronous and allows for serialization of maximum one message at a time.
DSP may respond with ADSP_PENDING status for a request - known as delayed reply - and when situation occurs, framework keeps the lock and awaits upcoming response through IPCD channel which is handled in bottom-half. Immediate replies spawn no BH at all as their processing is very short.

DSP designed for Lynxpoint and Wildcat Point offers no dynamic topology i.e. all pipelines are already defined within firmware and host is relegated to allocing stream for predefined pins. This is represented by 'catpt_topology' member.
Implementation covers all available pin types: - system playback and capture - two offload streams - loopback (reference) - bluetooth playback and capture
PCM DAI operations differentiate between those pins as some (mainly offload) are to be handled differently - DSP expects wp updates on each notify_position notification.
System playback has no volume control capability as it is routed to mixer stream directly. Other primary streams - capture and two offloads - offer individual volume controls.
Compared to sound/soc/intel/haswell this configures SSP device format automatically on pcm creation.

DSP designed for Lynxpoint and Wildcat Point offers no dynamic topology i.e. all pipelines are already defined within firmware and host is relegated to allocing stream for predefined pins. This is represented by 'catpt_topology' member.
Implementation covers all available pin types:
- system playback and capture
- two offload streams
- loopback (reference)
- bluetooth playback and capture
PCM DAI operations differentiate between those pins as some (mainly offload) are to be handled differently - DSP expects wp updates on each notify_position notification.
System playback has no volume control capability as it is routed to mixer stream directly. Other primary streams - capture and two offloads
- offer individual volume controls.
Compared to sound/soc/intel/haswell this configures SSP device format automatically on pcm creation.

This check seems bit suspicious to me, as CATPT_CHANNELS_MAX is 4 and you only check 2 of possible values here, while in else part, you loop over all possible 4 to set them? So there is chance that ctlvol[0] is equal to ctlvol[1], but ctlvol[2] and ctlvol[3] are different, what happens then?

DSP designed for Lynxpoint and Wildcat Point offers no dynamic topology i.e. all pipelines are already defined within firmware and host is relegated to allocing stream for predefined pins. This is represented by 'catpt_topology' member.
Implementation covers all available pin types:
- system playback and capture
- two offload streams
- loopback (reference)
- bluetooth playback and capture
PCM DAI operations differentiate between those pins as some (mainly offload) are to be handled differently - DSP expects wp updates on each notify_position notification.
System playback has no volume control capability as it is routed to mixer stream directly. Other primary streams - capture and two offloads
- offer individual volume controls.
Compared to sound/soc/intel/haswell this configures SSP device format automatically on pcm creation.

This check seems bit suspicious to me, as CATPT_CHANNELS_MAX is 4 and you only check 2 of possible values here, while in else part, you loop over all possible 4 to set them? So there is chance that ctlvol[0] is equal to ctlvol[1], but ctlvol[2] and ctlvol[3] are different, what happens then?
Check is simplified as majority of configurations make use of stereo only. Maybe it shouldn't have been. Will fix in v3.
Define tracing macros for easy catpt debug. These cover all IPC message types: requests, replies and notifications.

Prevent sound/soc/intel/haswell code compile and select catpt instead as a recommended solution. Userspace-exposed members are compatible with what is exposed by deprecated solution thus no harm is done. The only visible difference is the newly added 'Loopback Mute' kcontrol.

Thanks for the advice!
I'd like to keep format cohesive with the rest, though: restoring <type of context>: off 0x%08x size %d\n
%pr yields:

Casting to (unsigned long long) should be fine, judging by /kernel/resource.c, yes?

No. The rule of thumb that if you cast for printf() something is really needs to be checked (and 99% wrong).
Use %pa as per printk-formats.rst.
Remove code specific to sound/soc/intel/haswell. Update BE dai_link definition to provide seamless transition to catpt solution.
