[PATCH V2 01/10] ASoC: Intel: Skylake: Fix to delete DSP pipe after stopping pipe

[jeeja.kp]

From: Jeeja KP <jeeja.kp@intel.com>

DSP pipe needs to stopped before deleting the pipe. Currently check is
for pipe state > STARTED, which is incorrect. So changed to include
pipe state STARTED to stop the pipe if it started.

If the widget is a mixin module, just unbind between source and sink
and don't stop the source pipe as there can be multiple sinks

[PATCH V2 04/10] ASoC: Intel: bxtn: Update DSP core state in D0

[jeeja.kp]

From: Jeeja KP <jeeja.kp@intel.com>

In system suspend, firmware needs to be re-downloaded as IMR is cleared.
When firmware is downloaded in D0, core state is not set to running
state causing instability with subsequent D0-D3 cycles.

So set the core state correctly during D0 and check the DSP core state
if not in reset to set the DSP to D3.

[PATCH V2 09/10] ASoC: Intel: Skylake: Fix module load when module size > DMA buffer size

[jeeja.kp]

From: Jeeja KP <jeeja.kp@intel.com>

When module size > DMA buffer size, driver copies first chunk and waits
for the BDL complete interrupt. BDL complete interrupt never occurs and
wait time expires as module load IPC is not send to start the DMA from
DSP.

To fix the above issue need to follow the below steps:
1. After copying the first chunk, send the module load IPC to start the
DMA.
2. Wait for the BDL interrupt. Once interrupt is received, copy the
next chunk.
3. Continue step 2 till all bytes are copied.
4. When all the bytes are copied (bytes_left = 0), wait for module load
IPC response
5. Handled module load IPC response messages, check the load module IPC
response and wake up the thread to complete module load.

Applied "ASoC: Intel: Skylake: Fix module load when module size > DMA buffer size" to the asoc tree

[Mark Brown]

The patch

   ASoC: Intel: Skylake: Fix module load when module size > DMA buffer size

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] ASoC: Intel: Skylake: Fix module load when module size > DMA
 buffer size

When module size > DMA buffer size, driver copies first chunk and waits
for the BDL complete interrupt. BDL complete interrupt never occurs and
wait time expires as module load IPC is not send to start the DMA from
DSP.

To fix the above issue need to follow the below steps:
1. After copying the first chunk, send the module load IPC to start the
DMA.
2. Wait for the BDL interrupt. Once interrupt is received, copy the
next chunk.
3. Continue step 2 till all bytes are copied.
4. When all the bytes are copied (bytes_left = 0), wait for module load
IPC response
5. Handled module load IPC response messages, check the load module IPC
response and wake up the thread to complete module load.

[PATCH V2 10/10] ASoC: Intel: Skylake: Fix parameter overwrite for KPB Module

[jeeja.kp]

From: Dharageswari R <dharageswari.r@intel.com>

KPB module default parameter were overwritten by the dynamic instance
id once use case is executed. This will cause module crash from
subsequent execution of use case as the updated parameters are used.

So instead of over writing the default parameter, make a copy and
update the module parameter and use this in IPC message.
