[media] omap3isp: Move to videobuf2

2014-05-25T14:38:53+00:00

Replace the custom buffers queue implementation with a videobuf2 queue. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: Move buffer irqlist to isp_buffer structure

2014-05-25T14:33:27+00:00

This prepares for the move to videobuf2. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: Move queue irqlock to isp_video structure

2014-05-25T14:32:08+00:00

This prepares for the move to videobuf2. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: Move queue mutex to isp_video structure

2014-05-25T14:19:48+00:00

This prepares for the move to videobuf2. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: queue: Don't build scatterlist for kernel buffer

2014-05-25T14:19:08+00:00

The scatterlist is not needed for those buffers, don't build it. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: Use the ARM DMA IOMMU-aware operations

2014-05-25T14:18:42+00:00

Attach an ARM DMA I/O virtual address space to the ISP device. This switches to the IOMMU-aware ARM DMA backend, we can thus remove the explicit calls to the OMAP IOMMU map and unmap functions. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: queue: Map PFNMAP buffers to device

2014-05-25T14:17:14+00:00

Userspace PFNMAP buffers need to be mapped to the device like the userspace non-PFNMAP buffers in order for the DMA mapping implementation to create IOMMU mappings when we'll switch to the IOMMU-aware DMA mapping backend.

[media] omap3isp: queue: Allocate kernel buffers with dma_alloc_coherent

2014-05-25T14:15:47+00:00

And retrieve the related sg table using dma_get_sgtable(). Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: queue: Merge the prepare and sglist functions

2014-05-25T14:14:43+00:00

In preparation for the switch to the DMA API merge the two functions that handle buffer preparation for the USERPTR cases (both page-backed and non page-backed memory). Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: queue: Use sg_table structure

2014-05-25T14:14:02+00:00

Replace the sglen and sglist fields stored in the buffer structure with an sg_table. This allows using the sg table allocation helper function. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab
