Wed, 04 Feb 2026 12:18:54 +0100

ASoC: SOF: Intel: reserve link DMA for sdw bpt streamMerge series from Bard Liao :Currently, hda_sdw_bpt_dma_prepare() get a HDA stream and use the linkDMA but doesn't reserve it. It works fine because we assume theSwoundWire BPT will not run with audio streams simultaneously. Createand use the new helpers to reserve the link DMA and allow running BPTand audio stream simultaneously.Pierre adds:For the record this solution has two issues not documented in any commitmessage:a) this will not work in 'dspless' mode, where the link DMA is notenabled. That's probably fine given that no one used that mode inproduction, but that's a software restriction that you will not be ableto undo.b) this raise the question of how bandwidth will be managed. The premiseof BPT is that it uses all the bus bandwidth to guarantee predictablefirmware download times. If the available bandwidth is restricted byother audio streams, then mechanically the startup latency will beincreased and vary - or you will have to run the bus at a higherfrequency to provision enough bandwidth for BPT but that means higherpower consumption. Or you will have to change the bus clock dynamicallywhich is possible at the hardware level for SDCA parts but not legacyones.I am not going to lay on the tracks for this low-level set of changes,but you'll have to address the b) opens for future contributions.

dab6b6f5fc5aabd3248bdea4d6e200a04b309fd2 - ASoC: SOF: Support for on-demand DSP boot

Tue, 16 Dec 2025 20:12:22 +0100

ASoC: SOF: Support for on-demand DSP bootMerge series from Peter Ujfalusi :On system suspend / resume we always power up the DSP and boot thefirmware, which is not strictly needed as right after the firmware bootedup we power the DSP down again on suspend and we also power it down afterresume after some inactivity.Similarly, on jack insert/removal we needlesly boot up the firmware to checkthe jack status, which needs no DSP/firmware communication.The on-demand DSP boot will make sure that we boot the DSP firmware up onlywhen it is needed - for audio activity, in other cases the firmware will benot booted up, which saves time.Out of caution, add a new platform descriptor flag to enable on-demandDSP boot since this might not work without changes to platform code oncertain platforms.With the on-demand dsp boot enabled we will not boot the DSP and firmwareup on system or rpm resume, just enable audio subsystem since audio IPs,like HDA and SoundWire might be needed (codecs suspend/resume operation).Only boot up the DSP during the first hw_params() call when the DSP isreally going to be needed.In this way we can handle the audio related use cases:normal audio use (rpm suspend/resume)system suspend/resume without active audiosystem suspend/resume with active audiosystem suspend/resume without active audio, and audio start before the rpmsuspend timeoutAdd module option to force the on-demand DSP boot to allow it to bedisabled or enabled without kernel change for testing.The on-demand boot has been tested in our CI for more than half a yearand so far no issues have been seen on supported platforms since it'sintroduction to our development tree (sof-dev).
