HSV formats are extremely useful for image segmentation. This set of
patches makes v4l2 aware of this kind of formats.
Vivid changes have been divided to ease the reviewing process.
We are working on patches for Gstreamer and OpenCV that will make use
of these formats.
We still need to decide if
These formats store the color information of the image
in a geometrical representation. The colors are mapped into a
cylinder, where the angle is the HUE, the height is the VALUE
and the distance to the center is the SATURATION. This is a very
useful format for image segmentation algorithms.

Hi Benjamin, Wolfram,
Sorry for being late to the party. I finally found some time to look at

The goal of this patchset is to improve UIO framework and UIO dmem
driver to allow cache-coherent DMA accesses from user-space.
This patchset is based on two previous patchsets:
1) [PATCH v5 0/6] UIO driver for APM X-Gene QMTM
(Refer, http://www.spinics.net/lists/devicetree/msg58244.html)
2) [PATC
On ARM64, the MMU supports special memory attributes for device
memory/registers. Due to this we have pgprot_device() provided
by asm/pgtable.h of arch/arm64.
On architectures that do not have special MMU attribute for device
memory/registers, the asm-generic/pgtable.h maps pgprot_device()
to pgpr

The uio_dmem_genirq works in a similar ways as uio_pdrv_genirq now.
It accepts the of_id module parameter to specify UIO compatible
string as module parameter. There are few other module parameters
to specify number bits in DMA mask and sizes dynamic regions.
Following are th
From: Jan Viktorin
We can simplify handling of platform_get_irq into one place as it is
acceptable to see UIO_IRQ_NONE instead of a valid IRQ number. Some
devices don't have or don't need any interrupt to be handled. The
same change has been already done for uio_pdrv_genirq.
Signed-off-by: Jan V
This patch extends uio_dmem_genirq driver to use recently
added memtypes as follows:
1. Use UIO_MEM_DEVICE memtype for MEM resources
2. Use UIO_MEM_PHYS_CACHE memtype for dynamic regions
when UIO DT node is marked as DMA coherent.
