Hi Laurent co.,
I'd like to look at what the maximum possible frame rates are for a
sensor connected to the OMAP3 ISP CCDC via the parallel interface,
writing frames directly to memory. I understand that there is some
minimum amount of time required between frames to pass on the finished
Hi Laurent,
I am looking at a case where the sensor may stop delivering data, at
which point I want to do a STREAMOFF. In this case, the STREAMOFF takes
2s because of the wait_event_timeout() in ccdc_disable(). This wait
waits for ccdc-stopping to be CCDC_STOP_FINISHED, which happens in two

[media] omap3isp: implement ENUM_FMT
[media
ENUM_FMT will not enumerate all formats that the ISP is capable of,
it will only return the format which has been previously configured
using the media controller, because this is the only format available
to a V4L2 application which is unaware of the media controller.
Signed-off-by: Michael
This allows a V4L2 application which has no knowledge of the media
controller to open a video device node of the already-configured ISP
and query what it will deliver. Previously, G_FMT only worked after a
S_FMT had already been done.

Hi all,
I get a warning about a cache error with the following steps:
0. load omap3-isp
1. set up media broken media pipeline. (e.g. set different formats on
opposite ends of a link, as will be the case for using the lane shifter)
2. try to capture images. isp_video_streamon() returns -EPIPE
that this is a sensible approach, I will go ahead and
submit my patch soon.
thanks,
Michael

Hi all,
In the OMAP ISP driver, I'm interested in being able to choose between
8-bit and 12-bit formats when I have a 12-bit sensor attached. At the
moment it looks like it's only possible to define this statically with
data_lane_shift in the board definition. But with the ISP's lane
shifter,

Hi Laurent Sakari,
On Laurent's media-0006-sensors branch, when compiling with
CONFIG_VIDEO_OMAP3=m, I got the following linking error:
ERROR: omap_pm_set_min_bus_tput [drivers/media/video/isp/omap3-isp.ko]

I can get rid of the error with the patch below. But as always, I
wonder:
to fix this problem, however.
But I might be just pointing you to wrong direction, better wait for
Laurent's answer. :-)

not about the parallel sensor,
it's about writing the data from the CCDC to memory. I expect the
problem to occur with a serial sensor too if the CCDC writes to memory.

HS_VS_IRQ is _either_ VS _or_ HS interrupts, but not both. The SYNC_DETECT
bits in ISP_CTRL determines which. For writing into memory, the ISP only needs
to react per frame, not per line, so it is set up to trigger on VS.

it on to the last
link in the chain, but none of the subdevs in the ISP currently have a cropcap
function implemented (yet). Does this still need to be written?
