alsa-state: Add qoriq-*-bsp specific configuration

2025-05-05T14:02:42+00:00

This asound.conf can be used for both i.MX and Layerscale platforms. But the latter don't have imx--bsp in their overrides. So add symlinks for QorIQ platforms. This makes the package for QorIQ platforms machine-specific as well. Signed-off-by: Alexander Stein

asound.conf: default sample rate to 48000

2025-04-28T16:43:18+00:00

Change the default sample rate as used with ALSA to 48000 instead of 44100. Most newer content, videos, and web-based content uses 48 kHz sampling rate, especially with modern codecs like Opus. Normally applications request ALSA to use a PCM sample rate which matches the input content when starting playback. However, more complex applications such as Chromium will internally resample audio to match the default output. This can result in high CPU usage for resampling, so having ALSA's default rate match the majority of content is preferred.

alsa-state: Simplify FILESEXTREAPATHS to support NXP specific and Mainline BSP

2023-06-26T01:55:45+00:00

Current implement can only apply the setting under folder imx-generic-bsp. Use common paths setting for the NXP and mainline specific setting. Signed-off-by: Jun Zhu

alsa-state: Update asound.conf for linux-imx 5.15

2023-01-09T18:44:41+00:00

The multi-fifo script is integrated in linux-imx 5.15, and the channel mapping is handled by the kernel, so some pcm devices can be removed. Signed-off-by: Tom Hochstein

Rework recipes to use imx-generic-bsp more extensively

2022-02-21T23:06:28+00:00

This rework the recipes making use of new imx-generic-bsp override; it has been applied to: - alsa-state - firmware-imx - imx-kobs - imx-test - imx-uuc - linux-fslc - linux-fslc-lts - packagegroup-fsl-mfgtool - u-boot-fslc - uuu Signed-off-by: Otavio Salvador

Generalize overrides subsystem for NXP and Mainline support

2022-02-21T23:06:28+00:00

Essentially, we extend the overrides to a generic-bsp, nxp-bsp, and mainline-bsp. So, for example, the mx8mq override is split into: - imx-generic-bsp: compatible with every i.MX SoC and both BSP variants - imx-nxp-bsp: compatible with every i.MX SoC but specific to NXP BSP - imx-mainline-bsp: compatible with every i.MX SoC but specific to Mainline BSP - mx8-generic-bsp: compatible with every i.MX8 SoC and both BSP variants - mx8-nxp-bsp: compatible with every i.MX8 SoC but specific to NXP BSP - mx8-mainline-bsp: compatible with every i.MX8 SoC but specific to Mainline BSP - mx8m-generic-bsp: compatible with every i.MX8M SoC and both BSP variants - mx8m-nxp-bsp: compatible with every i.MX8M SoC but specific to NXP BSP - mx8m-mainline-bsp: compatible with every i.MX8M SoC but specific to Mainline BSP - mx8mq-generic-bsp: compatible with every i.MX8MQ SoC and both BSP variants - mx8mq-nxp-bsp: compatible with every i.MX8MQ SoC8 but specific to NXP BSP - mx8mq-mainline-bsp: compatible with every i.MX8MQ SoC but specific to Mainline BSP The extender mechanism is responsible for extending the override list to include the generic overrides. We can then use the three different variants to handle the metadata correctly. Generically speaking, the conversion mainly was automated (with a lot of back and forth until getting it right). To convert an existing layer, the following script can be used: ```sh git ls-files classes recipes-* \ | xargs sed -i \ -e 's,:$mx[6-8]\w*$,:\1-nxp-bsp,g' \ -e 's,($mx[6-8]\w*$),(\1-nxp-bsp),g' \ -e 's,$mx[6-8]\w*$|,\1-nxp-bsp|,g' \ -e 's,|$mx[6-8]\w*$),|\1-nxp-bsp),g' \ \ -e 's,:$mx[5s]\w*$,:\1-generic-bsp,g' \ -e 's,($mx[5s]\w*$),(\1-generic-bsp),g' \ -e 's,$mx[5s]\w*$|,\1-generic-bsp|,g' \ -e 's,|$mx[5s]\w*$),|\1-generic-bsp),g' \ \ -e 's,:$vf\w*$,:\1-generic-bsp,g' \ -e 's,:$vf[56]0\w*$,:\1-generic-bsp,g' \ -e 's,$vf\w*$|,\1-generic-bsp|,g' \ -e 's,|$vf\w*$),|\1-generic-bsp),g' \ -e 's,$vf[56]0\w*$|,\1-generic-bsp|,g' \ -e 's,|$vf[56]0\w*$),|\1-generic-bsp),g' \ \ -e 's,:$imx$ ,:\1-nxp-bsp ,g' \ -e 's,($imx$),(\1-nxp-bsp),g' \ -e 's,$imx$|,\1-nxp-bsp|,g' \ -e 's,|$imx$),|\1-nxp-bsp),g' for d in $(find -type d | egrep '/mx[6-8]w*'); do git mv $d $d-nxp-bsp done for d in $(find -type d | egrep '/imx$'); do git mv $d $d-nxp-bsp done for d in $(find -type d | egrep '/mx[5s]w*'); do git mv $d $d-generic-bsp done ``` Fixes: #791.
