[PATCH 4/7] tw686x: Add support for DMA scatter-gather mode

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. Signed-off-by: Ezequiel Garcia --- drivers/media/pci/tw686x/Kconfig| 1 +

[PATCH 2/7] tw686x: Introduce an interface to support multiple DMA modes

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

[PATCH 6/7] tw686x: audio: Allow to configure the period size

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. Signed-off-by: Ezequiel Garcia

[PATCH 0/7] media: tw686x: Improvements

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

[PATCH 1/7] tw686x: Specify that the DMA is 32 bits

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. Signed-off-by: Ezequiel Garcia

[PATCH 7/7] tw686x: audio: Prevent hw param changes while busy

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)

[PATCH 5/7] tw686x: audio: Implement non-memcpy capture

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.

[PATCH 3/7] tw686x: Add support for DMA contiguous interlaced frame mode

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

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. You
