This causes lots of problems and is *very* slow as well.
One of the main problems is that this prohibits the use of the control
framework since subdevs will be unloaded on power off which is not allowed
as long as they are used by a usb device.
Apparently the reason for doing this is to turn off a noisy tuner. My hardware
has no problem with that, and I wonder whether the hardware with that noisy
tuner wasn't just functioning improperly as I have never heard of noisy tuners.
Contact me if you have one of those devices and I can take a look whether the
tuner can't be powered off if necessary by letting the tuner subdevice go
into standby mode. Unloading the tuner module is just evil and is not the
right approach.

Here's the driver for the Renesas R-Car JPEG processing unit.
The driver is implemented within the V4L2 framework as a memory-to-memory
device. It presents two video nodes to userspace, one for the encoding part,
and one for the decoding part.
It was found that the only working mode for encoding is no markers output, so we
generate markers with software. In the current version of driver we also use
software JPEG header parsing because with hardware parsing performance is lower
than desired.
>From a userspace point of view the process is typical (S_FMT, REQBUF,
optionally QUERYBUF, QBUF, STREAMON, DQBUF) for both the source and destination
queues. STREAMON can return -EINVAL in case of mismatch of output and capture
queues format. Also during decoding driver can return buffers if queued
buffer with JPEG image contains image with inappropriate subsampling (e.g.
4:2:0 in JPEG and 4:2:2 in capture). If JPEG image and queue format dimensions
differ driver will return buffer on QBUF with VB2_BUF_STATE_ERROR flag.
During encoding the available formats are: V4L2_PIX_FMT_NV12M,
V4L2_PIX_FMT_NV12, V4L2_PIX_FMT_NV16, V4L2_PIX_FMT_NV16M for source and
V4L2_PIX_FMT_JPEG for destination.
During decoding the available formats are: V4L2_PIX_FMT_JPEG for source and
V4L2_PIX_FMT_NV12M, V4L2_PIX_FMT_NV16M, V4L2_PIX_FMT_NV12, V4L2_PIX_FMT_NV16
for destination.
Performance of current version:
1280x800 NV12 image encoding/decoding
decoding ~122 FPS
encoding ~191 FPS

On built-in kernels this warning will always splat, even if no ivtvfb
hardware is present, as this is part of the module init:
if (WARN(pat_enabled(),
"ivtvfb needs PAT disabled, boot with nopat kernel parameter\n")) {
Fix that by shifting the PAT requirement check out under the code
that does the "quasi-probe" for the device.
This device driver relies on an existing driver to find its own devices,
it looks for that device driver and its own found devices, then uses
driver_for_each_device() to try to see if it can probe each of those
devices as a frambuffer device with ivtvfb_init_card().
We tuck the PAT requiremenet check then on the ivtvfb_init_card() call
making the check at least require an ivtv device present before
complaining.

This commit implements frame decimation for stk1160, which allows
to support format changes instead of a static frame size.
The stk1160 supports independent row and column decimation, in two
different modes:
* set a number of rows/columns units to skip for each unit sent.
* set a number of rows/columns units to send for each unit skipped.
This effectively allows to achieve different frame scaling ratios.
The unit number can be set to either two row/columns sent/skipped,
or four row/columns sent/skipped. Since the video format (UYVY)
has 4-bytes, using a unit number of two row/columns results
in frame color 'shifting', so set to four row/columns sent/skipped.

Use the new v4l2_subdev_notify_event() helper function to deliver the
resolution change event to userspace via the v4l2 subdev event queue as
well as to the bridge driver using the callback notify mechanism.
This allows userspace applications to react to changes in resolution. This
is useful and often necessary for video pipelines where there is no direct
1-to-1 relationship between the subdevice converter and the video capture
device and hence it does not make sense to directly forward the event to
the video capture device node.

Buffers can be returned back to videobuf2 in driver's streamon handler. In
this case vb2_buffer_done() with buffer state VB2_BUF_STATE_QUEUED will
cause the driver's buf_queue vb2 operation to be called, queueing the same
buffer again only to be returned to videobuf2 using vb2_buffer_done() and so
on.
Add a new buffer state VB2_BUF_STATE_REQUEUEING which, when used as the
state argument to vb2_buffer_done(), will result in buffers queued to the
driver. Using VB2_BUF_STATE_QUEUED will leave the buffer to videobuf2, as it

porch is remainder of vertical blanking time.
For RB v2, horizontal blanking is fixed at 80 pixels. Horizontal sync
is fixed at 32. All horizontal timing counts (active pixels, front,
back porches) can be specified upto a precision of 1.
RB v2 allows for non standard aspect ratios. In RB v2 vsync does not
indicate aspect ratio. In absence of aspect ratio v4l2_detect_cvt()
cannot calculate image width from image height. Hence extending the
v4l2_detect_cvt() to pass image width in case of RB v2.

name "_named" suffix references to a device tree property, which contains
a phandle to a device and the corresponding device driver is assumed to
register a gen_pool object.
Due to a weak relation and to avoid any confusion (e.g. in future
possible scenario if gen_pool objects are named) the suffix is removed.

Pull drm updates from Dave Airlie:
"This is the main drm pull request for v4.2.
I've one other new driver from freescale on my radar, it's been posted
and reviewed, I'd just like to get someone to give it a last look, so
maybe I'll send it or maybe I'll leave it.
There is no major nouveau changes in here, Ben was working on
something big, and we agreed it was a bit late, there wasn't anything
else he considered urgent to merge.
There might be another msm pull for some bits that are waiting on
arm-soc, I'll see how we time it.

to the build in various configs,t hat I just applied.
Summary:
New drivers:
- virtio-gpu:
KMS only pieces of driver for virtio-gpu in qemu.
This is just the first part of this driver, enough to run
unaccelerated userspace on. As qemu merges more we'll start
adding the 3D features for the virgl 3d work.
- amdgpu:
a new driver from AMD to driver their newer GPUs. (VI+)
It contains a new cleaner userspace API, and is a clean

Relative measurements are typically between 0 and 0xffff. However,
for some tuners (TUNER_S7395 and TUNER_S0194), the range were from
0 to 0xff00, with means that 100% is never archived.
Also, TUNER_RS2000 uses a more complex math.
So, create a macro that does the conversion using bit operations
and use it for all conversions.
The code is also easier to read with is a bonus.

Both c_tmp and s_tmp actually stores a u16 stat. Using a u64 data
there is a waste, specially on u32 archs, as 64 ints there are more
expensive.
So, change the types to u32 and do the typecast only when storing
the result.

On some archs, like tile, the PAGE_SIZE is not 4K. In the case

Due to that, a warning is produced:
drivers/media/pci/saa7134/saa7134.h:678:43: warning: large integer implicitly truncated to unsigned type [-Woverflow]
This is actually an error, as it will write trach to the DMA size
registers. The logic at saa7134-ts already does the right thing:
saa_writeb(SAA7134_TS_DMA0, ((dev->ts.nr_packets-1)&0xff));

saa_writeb(SAA7134_TS_DMA2,

Pull x86 core updates from Ingo Molnar:
"There were so many changes in the x86/asm, x86/apic and x86/mm topics
in this cycle that the topical separation of -tip broke down somewhat -
so the result is a more traditional architecture pull request,
collected into the 'x86/core' topic.
The topics were still maintained separately as far as possible, so
bisectability and conceptual separation should still be pretty good -
but there were a handful of merge points to avoid excessive
dependencies (and conflicts) that would have been poorly tested in the
end.
The next cycle will hopefully be much more quiet (or at least will
have fewer dependencies).
The main changes in this cycle were:
* x86/apic changes, with related IRQ core changes: (Jiang Liu, Thomas
Gleixner)
- This is the second and most intrusive part of changes to the x86
interrupt handling - full conversion to hierarchical interrupt
domains:
[IOAPIC domain] -----
|
[MSI domain] --------[Remapping domain] ----- [ Vector domain ]
| (optional) |
[HPET MSI domain] ----- |
|
[DMAR domain] -----------------------------
|
[Legacy domain] -----------------------------
This now reflects the actual hardware and allowed us to distangle
the domain specific code from the underlying parent domain, which
can be optional in the case of interrupt remapping. It's a clear
separation of functionality and removes quite some duct tape
constructs which plugged the remap code between ioapic/msi/hpet
and the vector management.
- Intel IOMMU IRQ remapping enhancements, to allow direct interrupt
injection into guests (Feng Wu)
* x86/asm changes:
- Tons of cleanups and small speedups, micro-optimizations. This
is in preparation to move a good chunk of the low level entry
code from assembly to C code (Denys Vlasenko, Andy Lutomirski,
Brian Gerst)
- Moved all system entry related code to a new home under
arch/x86/entry/ (Ingo Molnar)
- Removal of the fragile and ugly CFI dwarf debuginfo annotations.
Conversion to C will reintroduce many of them - but meanwhile
they are only getting in the way, and the upstream kernel does
not rely on them (Ingo Molnar)
- NOP handling refinements. (Borislav Petkov)
* x86/mm changes:
- Big PAT and MTRR rework: making the code more robust and
preparing to phase out exposing direct MTRR interfaces to drivers -

Write-Through cached memory mappings. This is especially
important for good performance on NVDIMM hardware (Toshi Kani)
* x86/ras changes:
- Add support for deferred errors on AMD (Aravind Gopalakrishnan)
This is an important RAS feature which adds hardware support for
poisoned data. That means roughly that the hardware marks data
which it has detected as corrupted but wasn't able to correct, as
poisoned data and raises an APIC interrupt to signal that in the
form of a deferred error. It is the OS's responsibility then to
take proper recovery action and thus prolonge system lifetime as
far as possible.

Commit f61bf13b6a ("[media] vb2: add allow_zero_bytesused flag to the
vb2_queue struct") added a WARN_ONCE to catch usage of a deprecated API
using a zero value for v4l2_buffer.bytesused.
However, the condition is checked incorrectly, as the v4L2_buffer
bytesused field is supposed to be ignored for multiplanar buffers. This
results in spurious warnings when using the multiplanar API.
Fix it by checking v4l2_buffer.bytesused for uniplanar buffers and
v4l2_plane.bytesused for multiplanar buffers.

We are burrying direct access to MTRR code support on
x86 in order to take advantage of PAT. In the future, we
also want to make the default behavior of ioremap_nocache()
to use strong UC, at which point the use of mtrr_add() on
those systems would make write-combining void.
In order to help both enable us to later make strong
UC default and in order to phase out direct MTRR access
code, port the driver over to the arch_phys_wc_add() API
and annotate that the device driver requires systems to
boot with PAT disabled, with the 'nopat' kernel parameter.
This is a workable compromise given that the hardware is
really rare these days, and perhaps only some lost souls
stuck with obsolete hardware are expected to be using this
feature of the device driver.

Since when we start discussions about the usage Media Controller for
complex hardware, one thing become clear: the way it is, MC fails to
map anything different than capture/output/m2m video-only streaming.
The point is that MC has entities named as devnodes, but the only
devnode used (before the DVB patches) is MEDIA_ENT_T_DEVNODE_V4L.
Due to the way MC got implemented, however, this entity actually
doesn't represent the devnode, but the hardware I/O engine that
receives data via DMA.
By coincidence, such DMA is associated with the V4L device node
on webcam hardware, but this is not true even for other V4L2
devices. For example, on USB hardware, the DMA is done via the
USB controller. The data passes though a in-kernel filter that
strips off the URB headers. Other V4L2 devices like radio may not
even have DMA. When it have, the DMA is done via ALSA, and not
via the V4L devnode.
In other words, MC is broken as a whole, but tagging it as BROKEN
right now would do more harm than good.
So, instead, let's mark, for now, the DVB part as broken and
block all new changes to MC while we fix this mess, whith
we hopefully will do for the next Kernel version.

That doesn't make much sense. What the driver is actually trying
to do is to divide one second by a value. So, check the range
before dividing. That warrants the right result and will remove
the warnings on non-64 bits archs.
Also fixes this warning:

The embedded UART is apparently used to receive decoded IR (RC5?) codes.
Forward these scan codes to the RC framework and (where known) add
corresponding mapping tables to translate them into regular keys.
This patch has been tested on a TechniSat CableStar HD2. The mappings of other
rc-maps were taken from Christoph Pinkl's patch
(http://patchwork.linuxtv.org/patch/7217/) and the s2-liplianin repository. The
major difference to Christoph's patch is a reworked interrupt handling of the
UART because the RX interrupt is apparently level triggered and requires
masking until the FIFO is read by the UART worker.

Provide a DVBv5 API signal strength. This is in units of 0.001 dBm rather
than a percentage.
>From Antti Palosaari's testing with a signal generator, it appears that the
gain calculated according to Montage's specification if negated is a
reasonable representation of the signal strength of the generator.
To this end:
(1) Polled statistic gathering needed to be implemented in the TS2020 driver.
This is done in the ts2020_stat_work() function.
(2) The calculated gain is placed as the signal strength in the
dtv_property_cache associated with the front end with the scale set to
FE_SCALE_DECIBEL.
(3) The DVBv3 format signal strength then needed to be calculated from the
signal strength stored in the dtv_property_cache rather than accessing
the value when ts2020_read_signal_strength() is called.

The TS2020 and TS2022 tuners take an input from the demodulator indicating the
AGC setting on that component that is then used to influence the tuner's own
gain. This should be taken into account when calculating the gain and signal
strength.
Further, the existing TS2020 driver miscalculates the signal strength as the
result of its calculations can exceed the storage capacity of the 16-bit word
used to return it to userspace.
To this end:
(1) Add a callback function (->get_agc_pwm()) in the ts2020_config struct that
the tuner can call to get the AGC PWM value from the demodulator.
(2) Modify the TS2020 driver to calculate the gain according to Montage's
specification with the adjustment that we produce a negative value and
scale it to 0.001dB units (which is what the DVBv5 API will require):
(a) Callback to the demodulator to retrieve the AGC PWM value and then
turn that into Vagc for incorporation in the calculations. If the
callback is unset, assume a Vagc of 0.
(b) Calculate the tuner gain from a combination of Vagc and the tuner's RF
gain and baseband gain settings.
(3) Turn this into a percentage signal strength as per Montage's
specification for return to userspace with the DVBv3 API.
(4) Provide a function in the M88DS3103 demodulator driver that can be used to
get the AGC PWM value on behalf of the tuner.
(5) The ts2020_config.get_agc_pwm function should be set by the code that
stitches together the drivers for each card.
For the DVBSky cards that use the M88DS3103 with the TS2020 or the TS2022,
set the get_agc_pwm function to point to m88ds3103_get_agc_pwm.
I have tested this with a DVBSky S952 card which has an M88DS3103 and a TS2022.

struct timeval uses a 32-bit seconds representation which will
overflow in the year 2038 and beyond. This patch replaces
the usage of struct timeval with ktime_t which is a 64-bit
timestamp and is year 2038 safe.
This patch is part of a larger attempt to remove all instances
of 32-bit timekeeping variables (timeval, timespec, time_t)
which are not year 2038 safe, from the kernel.

The flexcop bridge chip has two banks of hardware pid filters -
an initial 6, and on some chip revisions an additional bank of 32.
A bug is present on the initial 6 - when changing transponders
one of two PAT packets from the old transponder would be included
in the initial packets from the new transponder. This usually
transpired with userspace programs complaining about services
missing, because they are seeing a PAT that they would not be
expecting. Running in full TS mode does not exhibit this problem,
neither does using just the additional 32.
This patch adds in an option to not use the inital 6 and solely use
just the additional 32, and enables this option for the SkystarS2
card. Other cards can be added as required if they also have
this bug.
