Currently, the driver has a fixed period size of 4096 bytes
(2048 frames). Since this hardware can configure the audio
capture size, this commit allows a period size range of [512-4096].
This is very useful to reduce the audio latency.

Hi,
This patchset contains two groups of improvements:
* Add support for frame (zero-copy) DMA mode,
and also scatter-gather DMA mode.
* Audio improvements: prevent hw param changes,
and allow period size configuration.
The DMA modes are selected at module insertion time,
through a modu
Set vb2_queue.gfp_flags to GFP_DMA32. Otherwise it will start to
create bounce buffers which is something you want to avoid since
those are in limited supply.
Without this patch, DMA scatter-gather may not work because
machines can ran out of buffers easily.

Now that the driver has the infrastructure to support more
DMA modes, let's add the DMA scatter-gather mode.
In this mode, the device delivers sequential top-bottom
frames.

Let's set the corner stone to support all the DMA modes
available on this device.
For stability reasons, the driver is currently setting DMA frame
mode, and using single DMA buffers to get the P and B buffers.
Each frame is then memcpy'ed into the user buffer.
However, other platforms might be in
Audio hw params are shared across all DMA channels,
so if the user changes any of these while any DMA channel is
enabled, it will impact the enabled channels, potentially causing
serious instability issues.
This commit avoids such situation, by preventing any hw param
change (on any DMA channel) i
Now that we've introduced the dma_mode parameter to pick the
DMA operation, let's use it to also select the audio DMA
operation.
When dma_mode != memcpy, the driver will avoid using memcpy
in the audio capture path, and the DMA hardware operation
will act directly on the ALSA buffers.

Now that the driver has the infrastructure to support more
DMA modes, let's add the DMA contiguous interlaced frame mode.
In this mode, the DMA P and B buffers are programmed with
the user-provided buffers. When a P (or B) frame is ready,
a new buffer is dequeued into P (or B).
In addition to int
Hi Charles-Antoine,
Thank you for the patch.
FIrst of all, we, on the ML, do prefer reading patches as sent by git
send-email tool.
It is easier to comment the patch.
Next, you should add a complete description to your commit. Just
having an object and a signed-off-by line is not enough.

Hi Helen,
This is just a quick look on it. See below.
