2019-10-25ASoC: SOF: Intel: only support INFO_BATCH for legacy platformsPierre-Louis Bossart
The current position update is not precise enough for PulseAudio to work reliably with the timer-based scheduling on Baytrail, Cherrytrail, Broadwell. Disable the NO_PERIOD_WAKEUP capability and use BATCH to signal that the position is only reliable and updated during period_elapsed events. This will be reverted when the firmware provides a more accurate position for those platforms.

2019-10-25ASoC: SOF: define INFO_ flags in dsp_opsPierre-Louis Bossart
Currently the INFO_ flags such as PAUSE/NO_PERIOD_WAKEUP are defined in the SOF PCM core, which doesn't scale. To account for platform variations, these flags need to be set in DSP ops. This patch only moves the definitions and does not change any functionality.

2019-08-09ASoC: SOF: Intel: byt: Refactor fw ready / mem windows creationDaniel Baluta
There is a lot of duplicate code when processing IPC firmware ready notification and creating memory windows. First step in reducing the code duplication is to introduce generic functions: * sof_get_windows * sof_fw_ready that will replace, in the first step, the specific implementation related to baytrail related platforms: * byt_get_windows * byt_fw_ready So we are basically moving code from intel/byt.c to loader.c keeping in mind that mbox_offset is a per platform constant so we need to use newly introduced snd_sof_dsp_get_mailbox_offset / snd_sof_dsp_get_window_offset in order to get the correct mbox offset / window offset value. Also, bar is a per platform constant so we use snd_sof_dsp_get_bar_index instead of the hardcoded BYT_DSP_BAR.

2019-08-09ASoC: SOF: Remove call to snd_sof_dsp_mailbox_initDaniel Baluta
This is reserved for some historical reason, we didn't enable memory windows for byt/bdw at the beginning, to make it compatible, we get those mailbox offsets from fw_ready struct firstly, and then update them if they existed in the following memory windows, to make sure the mailbox still can be used if no memory windows are created. With this change all platforms have the same implementation for xxx_fw_ready function so that we can refactor it in a common file.

2019-08-02ASoC: Remove dev_err() usage after platform_get_irq()Stephen Boyd
We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

2019-05-28ASoC: SOF: ipc: fix a race, leading to IPC timeoutsGuennadi Liakhovetski
Currently on all supported platforms the IPC IRQ thread first signals the sender when an IPC response is received from the DSP, then unmasks the IPC interrupt. Those actions are performed without holding any locks, so the thread can be interrupted between them. IPC timeouts have been observed in such scenarios: if the sender is woken up and it proceeds with sending the next message without unmasking the IPC interrupt, it can miss the next response. This patch takes a spin-lock to prevent the IRQ thread from being preempted at that point. It also makes sure, that the next IPC transmission by the host cannot take place before the IRQ thread has finished updating all the required IPC registers.
