ASoC: SOF: imx: Add i.MX8ULP HW support

2022-08-19T12:19:55Z

This adds skeleton support for the audio DSP hardware found on NXP i.MX8ULP platform. On i.MX8ULP resources (clocks, power, etc) are managed by the System Integration Module in LPAV domain and XRDC which is handled by arm trusted firmware.

ASoC: SOF: Compile and runtime IPC version selection

2022-06-14T10:22:12Z

The new IPC4 version is only supported by Intel platforms, iMX, AMD and MediaTek only uses the standard SOF IPC. There is no need for these platforms to build kernel support for IPC4 as it is just dead code for them. SND_SOC_SOF_IPC3 and SND_SOC_SOF_INTEL_IPC4 is introduced to allow compile time selection and exclusion of IPC implementations. To avoid randconfig failures add also support for runtime selection of the IPC ops in ipc.c based on sdev->pdata->ipc_type Signed-off-by: Peter Ujfalusi Reviewed-by: Bard Liao Reviewed-by: Ranjani Sridharan Link: https://lore.kernel.org/r/20220614075618.28605-1-peter.ujfalusi@linux.intel.com Signed-off-by: Mark Brown

ASoC: SOF: i.MX: simplify Kconfig

2021-11-16T14:29:59Z

Follow the Intel example and simplify the Kconfig a) start from the end-product for 'select' chains b) use 'depends on' to filter out configurations. c) use snd-sof-of as a common module without any 'select' Signed-off-by: Pierre-Louis Bossart Reviewed-by: Daniel Baluta Signed-off-by: Daniel Baluta Link: https://lore.kernel.org/r/20211116124131.46414-1-daniel.baluta@oss.nxp.com Signed-off-by: Mark Brown

ASoC: SOF: Introduce fragment elapsed notification API

2021-10-07T15:57:57Z

This patch prepares the introduction of the compress API with SOF. After each fragment is accepted by the DSP we need to inform the userspace applications that they can send the next fragment. This is done via snd_compr_fragment_elapsed. Similar with the PCM case, in order to avoid sending an IPC before the previous IPC is handled we need to schedule a delayed work to call snd_compr_fragment_elapsed(). See snd_sof_pcm_period_elapsed. To sum up this patch offers the following API to SOF code: * snd_sof_compr_init_elapsed_work * snd_sof_compr_fragment_elapsed Note that implementation for compressed function is in a new file selected via CONFIG_SND_SOC_SOF_COMPRESS invisible config option. This option is automatically selected for platforms that support the compress interface. For now only i.MX8 platforms support this. For symmetry we introduce snd_sof_pcm_init_elapsed_work to setup the work struct for PCM case.

ASoC: SOF: imx: Add debug support for imx platforms

2020-09-17T14:53:15Z

This patch adds debug support for imx platforms. This is important in order to gather information about the state of the DSP in case of an oops and the reason for the oops. This is done by checking if a message with a panic code has been placed in the debug box, in the imx8_dsp_handle_request function from sof/imx. If positive, the function imx8_dump, added in common, will be called. The first step is to gather information about the registers, filename, line number and stack by calling the imx8_get_registers, added in common. Then the information will be printed to the console by calling the get_status function.

ASoC: SOF: sof-of-dev: Add .arch_ops field

2020-08-26T12:19:16Z

Add .arch_ops field in the sof_imx8x_ops structure. The inclusion of this field will allow the usage of functions from sof/core.c in order to print debug information such as the registers and a stack dump in case of a firmware ops. The SND_SOC_SOF_XTENSA is added in the imx/Kconfig file so the compilation is successful.

ASoC: SOF: sort out Kconfig, again

2020-04-30T13:39:44Z

The imx8 config keeps causing issues: WARNING: unmet direct dependencies detected for SND_SOC_SOF_IMX8M Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=m] && SND_SOC_SOF_TOPLEVEL [=y] && SND_SOC_SOF_IMX_TOPLEVEL [=y] && IMX_DSP [=n] Selected by [m]: - SND_SOC_SOF_IMX_OF [=m] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=m] && SND_SOC_SOF_TOPLEVEL [=y] && SND_SOC_SOF_IMX_TOPLEVEL [=y] && SND_SOC_SOF_IMX8M_SUPPORT [=y] This is complicated by two drivers having dependencies on both platform specific drivers and the SND_SOC_SOF_OF framework code, and using an somewhat obscure method to build them the same way as the SOC_SOF_OF symbol (built-in or modular). My solution now ensures that the two drivers can only be enabled when the dependencies are met: - When the platform specific drivers are built-in, everything is fine, as SOC_SOF_OF is either =y or =m - When both are loadable modules, it also works, both for Kconfig and at runtime - When the hardware drivers are loadable modules or disabled, and SOC_SOF_OF=y, prevent the IMX_SOF_OF drivers from being turned on, as this would be broken. It seems that this is just an elaborate way to describe two tristate symbols that have straight dependencies, but maybe I'm missing some subtle point. It seems to always build for me now.
