provided by videobuf2. Since the CODA reports the I/P/B frame type of the

d19f405a5a [media] s5p-mfc: Fix selective sclk_mfc init
fc906b6d "Remove special clock usage in driver" removed
initialization of MFC special clock, arguing that there's
no need to do it explicitly, since it's one of MFC gate clock's
dependencies and gets enabled along with it. However, there's
no promise of keeping this hierarchy across Exynos SoC
releases, therefore this approach fails to provide a stable,
portable solution.

Out of all MFC versions, only v6 doesn't use special clock at all.
For other versions log a message only in case clk_get fails,
as not all the devices with the same MFC version require
initializing the clock explicitly.

&port->dvb cannot be null.

9409945c7f [media] v4l2-ioctl: call g_selection before calling cropcap
If the vidioc_cropcap op is implemented by the driver then the v4l2
core will call that directly.

If g_selection is available, then the core cropcap implementation
uses g_selection to fill in the bounds and defrect and it sets the
pixelaspect to 1x1.

But if both are available, then I would like to use g_selection to
fill in defrect and bounds before calling cropcap. That way the
driver's cropcap implementation doesn't have to set defrect or
bounds.

4bb7267dc4 [media] v4l: vb2: Add fatal error condition flag
When a fatal error occurs that render the device unusable, the only
options for a driver to signal the error condition to userspace is to
set the V4L2_BUF_FLAG_ERROR flag when dequeuing buffers and to return an
error from the buffer prepare handler when queuing buffers.

The buffer error flag indicates a transient error and can't be used by
applications to detect fatal errors. Returning an error from vb2_qbuf()
is thus the only real indication that a fatal error occurred. However,
this is difficult to handle for multithreaded applications that requeue
buffers from a thread other than the control thread. In particular the
poll() call in the control thread will not notify userspace of the
error.

This patch adds an explicit mechanism to report fatal errors to
userspace. Drivers can call the vb2_queue_error() function to signal a
fatal error. From this moment on, buffer preparation will return -EIO to
userspace, and vb2_poll() will set the POLLERR flag and return
immediately. The error flag is cleared when cancelling the queue, either
at stream off time (through vb2_streamoff) or when releasing the queue
with vb2_queue_release().

9241650d62 [media] v4l: vb2: Don't return POLLERR during transient buffer underruns
The V4L2 specification states that

"When the application did not call VIDIOC_QBUF or VIDIOC_STREAMON yet
the poll() function succeeds, but sets the POLLERR flag in the revents
field."

The vb2_poll() function sets POLLERR when the queued buffers list is
empty, regardless of whether this is caused by the stream not being
active yet, or by a transient buffer underrun.

Bring the implementation in line with the specification by returning
POLLERR if no buffer has been queued only when the queue is not
streaming. Buffer underruns during streaming are not treated specially
anymore and just result in poll() blocking until the next event.

960de2cff4 [media] v4l: vsp1: Setup control handler automatically at stream on time
When setting a control directly on a subdev node the VSP1 driver doesn't
guarantee that the device is powered on. This leads to crashes when the
control handlers writes to hardware registers. One easy way to fix this
is to ensure that the device gets powered on when a subdev node is
opened. However, this consumes power unnecessarily, as there's no need
to power the device on when setting formats on the pipeline.
Furthermore, control handler setup at entity init time suffers from the
same problem as the device isn't powered on easier.

Fix this by extend the entity base object to setup the control handler
automatically when starting the stream. Entities must then skip writing
to registers in the set control handler when not streaming, which can be
tested with the new vsp1_entity_is_streaming() helper function.

the v4l2_framebuffer structure which has no reserved fields either, and
in the v4l2_format structure which has reserved fields that were not
previously required to be zeroed out by applications.

To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer
structure, and use the priv field as a magic value to indicate that the
application has set all v4l2_pix_format extended fields and zeroed all
reserved fields following the v4l2_pix_format field in the v4l2_format
structure.

The availability of this API extension is reported to userspace through
the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the
priv field is still set to the magic value at [GS]_FMT return wouldn't
be enough, as older kernels don't zero the priv field on return.

To simplify the internal API towards drivers zero the extended fields
and set the priv field to the magic value for applications not aware of
the extensions.

d9a2547150 [media] v4l2-ctrls: add support for compound types
This patch implements initial support for compound types.

The changes are fairly obvious: basic support for is_ptr types, the
type_is_int function is replaced by a is_int bitfield, and
v4l2_query_ext_ctrl is added.

Note that this patch does not yet add support for N-dimensional
arrays, that comes later. So v4l2_query_ext_ctrl just sets elems to
1 and nr_of_dims and dims[] are all zero.

0ba2aeb6da [media] v4l2-ctrls: increase internal min/max/step/def to 64 bit
While VIDIOC_QUERYCTRL is limited to 32 bit min/max/step/def values
for controls, the upcoming VIDIOC_QUERY_EXT_CTRL isn't. So increase
the internal representation to 64 bits in preparation.

Because of these changes the msi3101 driver has been modified slightly
to fix a formatting issue (%d becomes %lld), vivi had to be modified
as well to cope with the new 64-bit min/max values and the PIXEL_RATE
control in a few sensor drivers required proper min/max/def values.

743162013d sched: Remove proliferation of wait_on_bit() action functions
The current "wait_on_bit" interface requires an 'action'
function to be provided which does the actual waiting.
There are over 20 such functions, many of them identical.
Most cases can be satisfied by one of just two functions, one
which uses io_schedule() and one which just uses schedule().

So:
 Rename wait_on_bit and        wait_on_bit_lock to
        wait_on_bit_action and wait_on_bit_lock_action
 to make it explicit that they need an action function.

 Introduce new wait_on_bit{,_lock} and wait_on_bit{,_lock}_io
 which are *not* given an action function but implicitly use
 a standard one.
 The decision to error-out if a signal is pending is now made
 based on the 'mode' argument rather than being encoded in the action
 function.

 All instances of the old wait_on_bit and wait_on_bit_lock which
 can use the new version have been changed accordingly and their
 action functions have been discarded.
 wait_on_bit{_lock} does not return any specific error code in the
 event of a signal so the caller must check for non-zero and
 interpolate their own error code as appropriate.

The wait_on_bit() call in __fscache_wait_on_invalidate() was
ambiguous as it specified TASK_UNINTERRUPTIBLE but used
fscache_wait_bit_interruptible as an action function.
David Howells confirms this should be uniformly
"uninterruptible"

The main remaining user of wait_on_bit{,_lock}_action is NFS
which needs to use a freezer-aware schedule() call.

A comment in fs/gfs2/glock.c notes that having multiple 'action'
functions is useful as they display differently in the 'wchan'
field of 'ps'. (and /proc/$PID/wchan).
As the new bit_wait{,_io} functions are tagged "__sched", they
will not show up at all, but something higher in the stack.  So
the distinction will still be visible, only with different
function names (gds2_glock_wait versus gfs2_glock_dq_wait in the
gfs2/glock.c case).

Since first version of this patch (against 3.15) two new action
functions appeared, on in NFS and one in CIFS.  CIFS also now
uses an action function that makes the same freezer aware
schedule call as NFS.

This allows drivers to vmap contiguous dma buffers so they can inspect the
buffer contents with the CPU. This will be needed for the CODA driver's JPEG
handling. On CODA960, the header parsing has to be done on the CPU. The
hardware modules can only process the entropy coded segment after all
registers and tables are set up.

3445857b22 [media] hdpvr: fix two audio bugs
When the audio encoding is changed the driver calls hdpvr_set_audio
with the current opt->audio_input value. However, that should have
been opt->audio_input + 1. So changing the audio encoding inadvertently
changes the input as well. This bug has always been there.

The second bug was introduced in kernel 3.10 and that broke the
default_audio_input module option handling: the audio encoding was
never switched to AC3 if default_audio_input was set to 2 (SPDIF input).

In addition, since starting with 3.10 the audio encoding is always set
at the start the first bug now always happens when the driver is loaded.
In the past this bug would only surface if the user would change the
audio encoding after the driver was loaded.

Also fixes a small trivial typo (bufffer -> buffer).

Currently gspca selects the first ISOC input endpoint as the input
transfer endpoint, however some devices can provide streams on endpoints
different then the first one, so some subdrivers (e.g. gspca_kinect) may
want to select a specific endpoint to use as a transfer endpoint.

Add an xfer_ep field to struct gspca_dev, and change alt_xfer() so that
it accepts a parameter which represents a specific endpoint address to
look for.

If a subdriver wants to specify a value for gspca_dev->xfer_ep it can do
that in its sd_config() callback.

1) at qv4l2, it fails the second time we try to open the

2) at xawtv, when audio underrun occurs, with is very
frequent, at least on my test machine.

For this callibration, I used adapter 0 (antenna 1), connected
via a normal cable to a DTF-2111 generator.

The same cabling and RF generator connected to adapter 1
(antenna 2) has a difference of +3dBm (signal was stronger
there).

Yet, changing the RF for a difference of, let's say, 6dB
reflected on a 6dB difference at the measured signal, with
is good.

So, the signal strengh can indeed be used to measure the
antenna gain, if the antenna is repositioned. It is
not precise to measure the absolute dBm value, however.

However, dib7000p_get_time_us() likely require some

for it to work with DVB-T. Still, better than nothing,
as latter patches can improve it.

This patch also doesn't show the signal strength in dB
yet. The code is already there, but it requires to be
callibrated.

A latter patch will do the calibration.

It seems that this patch is also a bug fix: Before this
patch, the frontend were not tuning with some userspace
tools. I suspect that dib7000p firmware or hardware
internally expects that the statistics to be collected,
in order for it to work. With this patch, the DVB core
will always retrive statistics, even if userspace doesn't

d44913c1e5 [media] dib8000: export just one symbol
Exporting multiple symbols don't work as it causes compilation
breakages, due to the way dvb_attach() works.

The bug happens when:
        CONFIG_DVB_DIB8000=m
	CONFIG_DVB_USB_DIB0700=y

As a bonus, dib8000 won't be loaded anymore if the device uses
a different frontend, reducing the memory footprint.

Tested with both Pixelview PV-D231 and MyGica S870.

b9bc7d59b7 [media] dib8000: rename dib8000_attach to dib8000_init
Well, what we call as "foo_attach" is the method that should
be called by the dvb_attach() macro.

It should be noticed that the name "dvb_attach" is really a
bad name and don't express what it does.

dvb_attach() basically does three things, if the frontend is
compiled as a module:
- It lookups for the module that it is known to have the
  given symbol name and requests such module;
- It increments the module usage (anonymously - so lsmod
  doesn't print who loaded the module);
- after loading the module, it runs the function associated
  with the dynamic symbol.

When compiled as builtin, it just calls the function given to it.

As dvb_attach() increments refcount, it can't be (easily)
called more than once for the same module, or the kernel
will deny to remove the module, because refcount will never
be zeroed.

In other words, the function name given to dvb_attach()
should be one single symbol that will always be called
before any other function on that module to be used.

For almost all DVB frontends, there's just one function,
but, on dib8000, there are several exported symbols.

We need to get rid of all those direct calls, because they
cause compilation breakages when bridge is builtin and
frontend is module, we'll need to add a new function that
will be the first one to be called, whatever initialization
is needed.

So, let's rename this function, in order to prepare for
a next patch that will add a new attach() function that
will be the only one exported by this module.

8abe4a0a3f [media] dib7000: export just one symbol
Exporting multiple symbols don't work as it causes compilation
breakages, due to the way dvb_attach() works.

This were reported several times, like:

   drivers/built-in.o: In function `cxusb_dualdig4_rev2_tuner_attach':

   drivers/built-in.o: In function `cxusb_dualdig4_rev2_frontend_attach':

In this specific report:
	CONFIG_DVB_USB_CXUSB=y
	CONFIG_DVB_DIB7000P=m

But the same type of bug can happen if:
	CONFIG_DVB_DIB7000P=m
and one of the bridge drivers is compiled builtin (cxusb, cx23885-dvb
and/or dib0700).

As a bonus, dib7000p won't be loaded anymore if the device uses
a different frontend, reducing the memory footprint.

Tested with Hauppauge Nova-TD (2 frontends).

should be one single symbol that will always be called
before any other function on that module to be used.

For almost all DVB frontends, there's just one function.

However, the dib7000p initialization can require up to 3
functions to be called:
	- dib7000p_get_i2c_master;
	- dib7000p_i2c_enumeration;
	- dib7000p_init (before this patch dib7000_attach).

(plus a bunch of other functions that the bridge driver will
need to call).

As we need to get rid of all those direct calls, because they
cause compilation breakages when bridge is builtin and
frontend is module, we'll need to add a new function that
will be the first one to be called, whatever initialization
is needed.

So, let's rename the function that probes and init the hardware
to dib7000p_init.

A latter patch will add a new dib7000p_attach that will be
used as originally conceived by dvb_attach() way.

Change handling of signal_lock on rs2000. Use ibuf[2] to detect
lock as there is a longer wait for lock to appear in ibuf[6].

Remove last_key and key_timeout and use jiffies plus 60ms
to detect that streaming is still active.

If the current jiffies is time_after the interrupt urb overdue and
clear signal lock.

This results in far faster recovery of lock and streaming.

4015bef649 [media] media: davinci: vpif_capture: drop unneeded module params
Remove bogus 'numbuffers' and 'bufsize' module options. The number of buffers and
buffer sizes are determined by VIDIOC_REQBUFS and VIDIOC_S_FMT and the amount of
available memory (in the case of the MMAP stream I/O mode) and not by module
options.

These module params are a left-over from the original montavista code that used
these parameters to pre-allocate the memory needed for the buffers. The code that
allocated those buffers was never upstreamed since by the time the drivers were
added to the kernel the TI cmem module could be used in combination with the
USERPTR mode to reserve and pass physically contiguous memory pointers around.

These days of course CMA is used instead of cmem.

This patch removes these module options altogether since they no longer do what
they originally were designed for. They should never have been part of the
upstreamed code in the first place, so they've been pointless ever since
2.6.32 when this driver first appeared in the mainline kernel.

f6fef86341 [media] au0828: reset streaming when a new frequency is set
As reported by Trevor, doing several opening/streaming/closing
operations to the demux causes it to fail.

I was able to simulate this bug too. I also noticed that,
sometimes, changing channels with au0828, the same thing
happens.

Most of the issues seem to be due to some hardware bug, that
causes the device to not fill all the URBs allocated. When
the bug happens, the only known fix is to either replug the
device, or to send an USB reset to it.

There's also a hack a the au0828 driver that starts a thread
that tries to reset the device when a package doesn't start
with a sync.

One of the culpits for this bad hardware behavior seem to be
caused by the lack of stopping and restarting the stream every
time a new channel is set.

This patch warrants that the stream will be properly reset
every time the set_frontend callback is called, partially
solving the problem.

A complete fix, however, would also need to check the PM
conditions for the tuner and demux.
