ASoC: SOF: Intel: hda: Introduce skip_imr_boot flag

2022-07-12T12:45:05+00:00

Use a dedicated flag instead of directly checking the sdev->system_suspend_target to decide if we need to skip IMR boot due to too deep sleep state where the memory used for IMR booting will not retain its content. The skip_imr_boot flag will be set true during suspend if the target state is deeper than S3 and reset back to false on successful boot to re-enable IMR booting in shallower sleep states.

ASoC: SOF: Intel: disable IMR boot when resuming from ACPI S4 and S5 states

2022-06-17T09:46:14+00:00

The IMR was assumed to be preserved when suspending to S4 and S5 states, but community reports invalidate that assumption, the hardware seems to be powered off and the IMR memory content cleared. Make sure regular boot with firmware download is used for S4 and S5.

ASoC: SOC: Intel: introduce cl_init callback

The code loader init sequences are different between versions of Intel platforms. Have a cl_init callback allows us to reuse the common code. No function changed.

ASoC: SOF: Intel: hda-loader: Make sure that the fw load sequence is followed

2022-06-09T10:27:37+00:00

The hda_dsp_enable_core() is powering up _and_ unstall the core in one call while the first step of the firmware loading must not unstall the core. The core can be unstalled only after the set cpb_cfp and the configuration of the IPC register for the ROM_CONTROL message.

ASoC: SOF: Intel: hda: Revisit IMR boot sequence

2022-04-22T23:16:27+00:00

The sequence for IMR boot is essentially the same as normal boot with the difference that instead of DMA from host the firmware is loaded from IMR. Re-structure the code to use the existing sequence and also add fallback handling in case the IMR boot fails. Introduce a new flag to make the IMR boot support check simpler.
