2020-09-21ASoC: SOF: control: fix size checks for ext_bytes control .get()Pierre-Louis Bossart1-1/+7
cppcheck complains twice: sound/soc/sof/control.c:436:2: style: Assignment of function parameter has no effect outside the function. [uselessAssignmentArg] size -= sizeof(const struct snd_ctl_tlv); ^ sound/soc/sof/control.c:436:7: style: Variable 'size' is assigned a value that is never used. [unreadVariable] size -= sizeof(const struct snd_ctl_tlv); Somehow we dropped the checks for the size argument when upstreaming the code, somewhere between v5 and v6. Re-add a size check to avoid providing userspace with more data that it asked for. Also fix all error codes, we should return -ENOSPC instead of -EINVAL.

2020-09-17ASoC: SOF: fix range checksGuennadi Liakhovetski1-16/+22
On multiple locations checks are performed of untrusted values after adding a constant to them. This is wrong, because the addition might overflow and the result can then pass the check, although the original value is invalid. Fix multiple such issues by checking the actual value and not a sum of it and a constant.

Move all the audio-specific code in the core, audio-specific logic in the top-level PM callbacks and the core header files into a separate file (sof-audio.*) in preparation for adding an audio client device. In the process of moving all structure definitions for widget, routes, pcm's etc, the snd_sof_dev member in all these structs is replaced with the snd_soc_component member. Also, use the component device instead of the snd_sof_dev device wherever possible in the PCM component driver, control IO functions and the topology parser as the component device will be moved over to the client device later on.

All the kcontrol put() functions are currently returning 0 when successful. This does not go well with alsamixer as it does not seem to get notified on SND_CTL_EVENT_MASK_VALUE callbacks when values change for (some of) the sof kcontrols.

2019-04-28ASoC: SOF: Add Sound Open Firmware KControl supportLiam Girdwood1-0/+552
SOF exposes regular ALSA Kcontrols that are defined by topology. This patch converts the Kcontrol IO to DSP IPC. The current implementation is aligned with previous Intel solutions, but is not optimal and can be improved: a) for every get/put the host wakes up the DSP and generates an IPC. The kernel should cache the values and generate an IPC only when strictly necessary. b) the firmware can be implemented to only instantiate the pipelines and related control-related parts that are needed at a given time, and power-gate the relevant SRAM blocks. The development tasks for these two improvements has started, once validated they will be provided in an update.
