2022-08-17Revert "devcoredump: remove the useless gfp_t parameter in dev_coredumpv and ↵Greg Kroah-Hartman1-1/+1
dev_coredumpm" commit 38a523a2946d3a0961d141d477a1ee2b1f3bdbb1 upstream. This reverts commit 77515ebaf01920e2db49e04672ef669a7c2907f2 as it causes build problems in linux-next. It needs to be reintroduced in a way that can allow the api to evolve and not require a "flag day" to catch all users.

2022-08-17devcoredump: remove the useless gfp_t parameter in dev_coredumpv and ↵Duoming Zhou1-1/+1
dev_coredumpm [ Upstream commit 77515ebaf01920e2db49e04672ef669a7c2907f2 ] The dev_coredumpv() and dev_coredumpm() could not be used in atomic context, because they call kvasprintf_const() and kstrdup() with GFP_KERNEL parameter. The process is shown below: dev_coredumpv(.., gfp_t gfp) dev_coredumpm(.., gfp_t gfp) dev_set_name kobject_set_name_vargs kvasprintf_const(GFP_KERNEL, ...); //may sleep kstrdup(s, GFP_KERNEL); //may sleep This patch removes gfp_t parameter of dev_coredumpv() and dev_coredumpm() and changes the gfp_t parameter of kzalloc() in dev_coredumpm() to GFP_KERNEL in order to show they could not be used in atomic context.

During stream start DSP firmware requires LPCS disabled as that moment in time is resource heavy.

2020-11-16ASoC: Intel: catpt: Skip position update for unprepared streamsCezary Rojewski1-0/+2
Playing with very low period sizes may lead to timeouts when awaiting RESET_STREAM reply for offload streams. This is caused by NOTIFY_POSITION appearing in the middle of trigger(stop). Stream is unprepared during trigger(stop) where PAUSE_STREAM IPC gets invoked. However, all data that is already mixed in DSP firmware's mixer stream will still be played regardless of the pause. For offload streams, this means possibility for another NOTIFY_POSITION to process. Keep these notifications in check by only handling them when stream is in prepared state.

2020-10-14ASoC: Intel: catpt: Relax clock selection conditionsCezary Rojewski1-3/+6
Stress tests show that DSP may occasionally be late with signaling WAIT state when all pins are made use of simultaneously plus start/stop (pause) gets involved. While this isn't tied to standard audio scenarios where only System Pin (playback and capture) is involved, ensure user is not hindered when playing with more advanced scenarios. >From DSP perspective, clock acts as a resource: low clock equals less resources, high clock more resources. Relax clock selection procedure so only low -> high switch is allowed when awaiting WAIT signal times out. Once active stream count decreases, DSP will have more time internally to adjust thus low clock selection becomes possible again.

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.

2020-10-02ASoC: Intel: catpt: Firmware loading and context restoreCezary Rojewski2-0/+631
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.
