5 years agomedia: vim2m: don't accept YUYV anymore as output format
Mauro Carvalho Chehab [Fri, 1 Mar 2019 12:41:24 +0000 (07:41 -0500)]
media: vim2m: don't accept YUYV anymore as output format

Handling any Y,Cr,Cb formats require some extra logic, as it
handles a group of two pixels. That's easy while we don't do
horizontal scaling.

However, doing horizontal scaling with such formats would require
a lot more code, in order to avoid distortions, as, if it scales
to two non-consecutive points, the logic would need to read 4
points in order to properly convert to RGB.

As this is just a test driver, and we want fast algorithms,
let's just get rid of this format as an output one.

5 years agomedia: vim2m: better handle cap/out buffers with different sizes
Mauro Carvalho Chehab [Tue, 26 Feb 2019 11:36:00 +0000 (06:36 -0500)]
media: vim2m: better handle cap/out buffers with different sizes

The vim2m driver doesn't enforce that the capture and output
buffers would have the same size. Do the right thing if the
buffers are different, zeroing the buffer before writing,
ensuring that lines will be aligned and it won't write past
the buffer area.

This is a temporary fix.

A proper fix is to either implement a simple scaler at vim2m,
or to better define the behaviour of M2M transform drivers
at V4L2 API with regards to its capability of scaling the
image or not.

In any case, such changes would deserve a separate patch
anyway, as it would imply on some behavoral change.

Also, as we have an actual bug of writing data at wrong
places, let's fix this here, and add a mental note that
we need to properly address it.

5 years agomedia: vim2m: use different framesizes for bayer formats
Mauro Carvalho Chehab [Thu, 28 Feb 2019 06:25:50 +0000 (01:25 -0500)]
media: vim2m: use different framesizes for bayer formats

The only real restriction at vim2m is that width should be
multiple of two, as the copy routine always copy two pixels
each time.

However, Bayer formats are defined as having a 2x2 matrix.
So, odd vertical numbers would cause color distortions at the
last line. So, it makes sense to use step 2 for vertical alignment
on Bayer.

With this patch, the reported formats for video capture will
be:

[0]: 'RGBP' (16-bit RGB 5-6-5)
Size: Stepwise 32x32 - 640x480 with step 2/1
[1]: 'RGBR' (16-bit RGB 5-6-5 BE)

media: ov7740: fix runtime pm initialization

The runtime PM of this device is enabled after v4l2_ctrl_handler_setup(),
and this makes this device's runtime PM usage count a negative value.

The ov7740_set_ctrl() tries to do something only if the device's runtime
PM usage counter is nonzero.

ov7740_set_ctrl()
{
if (!pm_runtime_get_if_in_use(&client->dev))
return 0;

<do something>;

pm_runtime_put(&client->dev);

return ret;
}

However, the ov7740_set_ctrl() is called by v4l2_ctrl_handler_setup()
while the runtime PM of this device is not yet enabled.  In this case,
the pm_runtime_get_if_in_use() returns -EINVAL (!= 0).

Therefore we can't bail out of this function and the usage count is
decreased by pm_runtime_put() without increment.

This fixes this problem by enabling the runtime PM of this device before
v4l2_ctrl_handler_setup() so that the ov7740_set_ctrl() is always called
when the runtime PM is enabled.

media: sun6i: Add support for JPEG media bus format

The CSI controller can take raw data from the data bus and output it
directly to capture buffers. This can be used to support the JPEG media
bus format.

While the controller can report minimum and maximum bytes per line, it
has no way to report how many lines were captured in the last frame.
Thus, even when the on-bus data is framed correctly, we have no way to
accertain the actual amount of data captured, unless we scan the buffer
for JPEG EOI markers, or sequential zeros. For now we leave bytesused
