Hello,
this is the second version of the proposed implementation for mem-to-mem memory
device framework. Your comments are very welcome.
Changes since v1:
- v4l2_m2m_buf_queue() now requires m2m_ctx as its argument
- video_queue private data stores driver private data
- a new submenu in kconfig f
A mem-to-mem device is a device that uses memory buffers passed by
userspace applications for both source and destination data. This is
different from existing drivers, which use memory buffers for only one
of those at once.
In terms of V4L2 such a device would be both of OUTPUT and CAPTURE type.
This is a virtual device driver for testing the mem-to-mem V4L2 framework.
It simulates a device that uses memory buffers for both source and
destination, processes the data and issues an "IRQ" (simulated by a timer).
The device is capable of multi-instance, multi-buffer-per-transaction
operation (
This is an example application for testing mem-to-mem framework using
mem2mem-testdev device.
It is intended to be executed multiple times in parallel to test multi-instance
operation and scheduling. Each process can be configured differently using
command-line arguments.
The application opens vi

Hello,
this is a driver for Samsung S3C/S5P series image rotator device driver.
This driver utilizes the proposed memory-to-memory V4L2 framework, just posted
by me in the previous patch series.
An example application for testing the device is also included.
This series contains:
[PATCH 1/2] [
The rotator device present on Samsung S3C and S5P series SoCs allows image
rotation and flipping. It requires contiguous memory buffers to operate,
as it does not have scatter-gather support. It is also an example of
a memory-to-memory device, and so uses the mem-2-mem device V4L2 framework.

Hi,
I'm trying to compile v4l on Fedora 11, latest available RPM kernel, but
there are many problem.
I've tried to go in the past with revision (hg update ), and
the last revision I can compile without problem is 13823.
Is this a know bug/error due to have not last kernel?
Thanks for the help

Hi Murali,
Sorry for the long delay in reviewing this patch series. I've been very busy,
first at work, and now for Christmas preparations (and occasionally I'd like
to relax as well :-) ).

Hans,
The change is because of the void * type that we use. Since ccdc parameter
structures are different for different IPs, a constant type for this arg
is not possible. The ccdc driver needs the pointer to structure. But the

Hi,
I would like to add support for cached user mapping to
videobuf-dma-contig.c.
For enabling this, "vma->vm_page_prot =
pgprot_noncached(vma->vm_page_prot);" line should be removed.
But now we should ensure user mapping cache coherency.
For that, for a camera we should :
- invalidate cache bef

Hi,
one of the sensors managed by the gspca_gl860 has some weird
resolutions : 800 x 598 and 1600 x 1198. To set these resolutions to
800 x 600 and 1600 x 1200 causes a flickering effect because of both
missing lines of data from the sensor. Thus a stupid question, does
the resolutions are these c

I wrote several patches those days in order to allow dvb-apps to properly

On ISDB-T, there are several new parameters, so the parsing is more complex
than all the other currently supported video standards.
