2014-05-25[media] omap3isp: Move to videobuf2Laurent Pinchart
Replace the custom buffers queue implementation with a videobuf2 queue. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-05-25[media] omap3isp: Move queue irqlock to isp_video structureLaurent Pinchart
This prepares for the move to videobuf2. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-05-25[media] omap3isp: Move queue mutex to isp_video structureLaurent Pinchart
This prepares for the move to videobuf2. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-05-25[media] omap3isp: queue: Don't build scatterlist for kernel bufferLaurent Pinchart
The scatterlist is not needed for those buffers, don't build it. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-05-25[media] omap3isp: Use the ARM DMA IOMMU-aware operationsLaurent Pinchart
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 <laurent.pinchart@ideasonboard.com> Acked-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-05-25[media] omap3isp: queue: Use sg_alloc_table_from_pages()Laurent Pinchart
Replace the custom implementation with a call to the scatterlist helper function. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-05-25[media] omap3isp: queue: Map PFNMAP buffers to deviceLaurent Pinchart
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. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-05-25[media] omap3isp: queue: Fix the dma_map_sg() return value checkLaurent Pinchart
dma_map_sg() can merge sglist entries, and can thus return a number of mapped entries different than the original value. Don't consider this as an error. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-05-25[media] omap3isp: queue: Allocate kernel buffers with dma_alloc_coherentLaurent Pinchart
And retrieve the related sg table using dma_get_sgtable(). Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-05-25[media] omap3isp: queue: Inline the ispmmu_v(un)map functionsLaurent Pinchart
The ispmmu_vmap() and ispmmu_vunmap() functions are just wrappers around omap_iommu_vmap() and omap_iommu_vunmap(). Inline them. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-05-25[media] omap3isp: queue: Merge the prepare and sglist functionsLaurent Pinchart
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 <laurent.pinchart@ideasonboard.com> Acked-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-05-25[media] omap3isp: queue: Use sg_table structureLaurent Pinchart
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 <laurent.pinchart@ideasonboard.com> Acked-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-05-25[media] omap3isp: queue: Move IOMMU handling code to the queueLaurent Pinchart
As a preparation for the switch from the OMAP IOMMU API to the DMA API move all IOMMU handling code from the video node implementation to the buffers queue implementation. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2013-12-18[media] omap3isp: Fix buffer flags handling when querying bufferLaurent Pinchart
A missing break resulted in all done buffers being flagged with V4L2_BUF_FLAG_QUEUED. Fix it. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2012-12-27[media] omap3isp: ispqueue: Fix uninitialized variable compiler warningsLaurent Pinchart
drivers/media/platform/omap3isp/ispqueue.c:399:18: warning: 'pa' may be used uninitialized in this function [-Wuninitialized] This is a false positive but the compiler has no way to know about it, so initialize the variable to 0. drivers/media/platform/omap3isp/ispqueue.c:445:6: warning: 'vm_page_prot' may be used uninitialized in this function [-Wuninitialized] This is a false positive and the compiler should know better. Use uninitialized_var(). Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-12-21[media] v4l: Tell user space we're using monotonic timestampsSakari Ailus
Set buffer timestamp flags for videobuf, videobuf2 and drivers that use neither. Signed-off-by: Sakari Ailus <sakari.ailus@iki.fi> Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-08-15[media] rename drivers/media/video as .../platformMauro Carvalho Chehab
The remaining drivers are mostly platform drivers. Name the dir to reflect it. It makes sense to latter break it into a few other dirs. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
