[PATCH] ASoC: SOF: core: allow module parameter to override dma trace Kconfig
by Pierre-Louis Bossart 13 Sep '21

13 Sep '21

Most distributions do not enable the SOF developer options and specifically the DMA trace. This is problematic for end-user/community support since the sof-logger tool cannot extract valuable information. Conversely in rare cases the DMA trace can lead to Heisenbugs by creating more traffic to system memory and more interrupts. This patch changes the logic so that the Kconfig value is used as a default value for a module parameter, but this value can be changed as needed. Users can override the distro DMA trace selection.

[PATCH] ASoC: SOF: Handle control change notification from firmware
by Peter Ujfalusi 13 Sep '21

13 Sep '21

If the value/data associated with a control changes in SOF it will send a notification (SOF_IPC_GLB_COMP_MSG with SOF_IPC_COMP_GET_VALUE/DATA). We have support for binary volatile control type, but we might have features where enum/switch/volume changes. Re-implementing everything as volatile as well would be not much of a gain for several reasons: - volatile controls would do an IPC all the time, regardless if there is a need or not. - We still don't have notification which forces userspace to continuously poll. When such notification arrives we use snd_ctl_notify_one() to signal userspace about the change. The kernel is prepared for two types of notification: - the notification carries the new data for the control (num_elems != 0) The new value/data is copied to the control's local data - blank message about a change The new flag for the scontrol (comp_data_dirty) is set and when next time user space reads the value via the kcontrol's get callback we will refresh the control's local data from the firmware.

[PATCH] ASoC: ti: rename CONFIG_SND_SOC_DM365_VOICE_CODEC_MODULE
by Masahiro Yamada 13 Sep '21

13 Sep '21

Kconfig generates include/generated/autoconf.h to make CONFIG options available to the pre-processor. Symbols with the value 'm' are suffixed with '_MODULE' Here is a conflict; CONFIG_FOO=m results in '#define CONFIG_FOO_MODULE 1', but CONFIG_FOO_MODULE=y also results in the same define. Also, CONFIG options that end with '_MODULE' confuse the Kconfig/fixdep interaction; fixdep always assumes CONFIG_FOO_MODULE comes from CONFIG_FOO=m, so the dependency is not properly tracked for symbols that end with '_MODULE'. For these reasons, CONFIG options that end with '_MODULE' should be avoided in general. (I am planning on adding a check in Kconfig.) This is the only case in the current kernel. The new option name was suggested by Péter Ujfalusi.
