The userspace-provided plane data needs to be stored in
vb2_v4l2_buffer. Currently this information is applied by
__fill_vb2_buffer() which is called by the core prepare_buf
and qbuf functions, but when using requests these functions
aren't called yet since the buffer won't be prepared until
the media request is actually queued.
In the meantime this information has to be stored somewhere
and vb2_v4l2_buffer is a good place for it.
The __fill_vb2_buffer callback now just copies the relevant

2) Add struct media_request to store request objects.
3) Add struct media_request_object to represent a request object.
4) Add MEDIA_REQUEST_IOC_QUEUE/REINIT ioctl support.
Basic lifecycle: the application allocates a request, adds
objects to it, queues the request, polls until it is completed
and can then read the final values of the objects at the time
of completion. When it closes the file descriptor the request
memory will be freed (actually, when the last user of that request
releases the request).
Drivers will bind an object to a request (the 'adds objects to it'
phase), when MEDIA_REQUEST_IOC_QUEUE is called the request is
validated (req_validate op), then queued (the req_queue op).
When done with an object it can either be unbound from the request
(e.g. when the driver has finished with a vb2 buffer) or marked as
completed (e.g. for controls associated with a buffer). When all
objects in the request are completed (or unbound), then the request
fd will signal an exception (poll).

Here is the bit set of char/misc drivers for 4.19-rc1
There is a lot here, much more than normal, seems like everyone is
writing new driver subsystems these days... Anyway, major things here
are:
- new FSI driver subsystem, yet-another-powerpc low-level
hardware bus
- gnss, finally an in-kernel GPS subsystem to try to tame all of
the crazy out-of-tree drivers that have been floating around
for years, combined with some really hacky userspace
implementations. This is only for GNSS receivers, but you
have to start somewhere, and this is great to see.
Other than that, there are new slimbus drivers, new coresight drivers,
new fpga drivers, and loads of DT bindings for all of these and existing
drivers.
Full details of everything is in the shortlog.
All of these have been in linux-next for a while with no reported
issues.

As we can compile-test all the dependency, the extra '| COMPILE_TEST' is
not needed to get the build coverage, and we can simply turn MFD_CROS_EC
into a hard dependency to make it build in all configurations.

The vivid driver uses a complex logic to save one kalloc/kfree
allocation. That non-trivial way of allocating data causes
smatch to warn:
drivers/media/platform/vivid/vivid-core.c:869 vivid_create_instance() warn: potentially one past the end of array 'dev->query_dv_timings_qmenu[dev->query_dv_timings_size]'
drivers/media/platform/vivid/vivid-core.c:869 vivid_create_instance() warn: potentially one past the end of array 'dev->query_dv_timings_qmenu[dev->query_dv_timings_size]'
I also needed to read the code several times in order to understand
what it was desired there. It turns that the logic was right,
although confusing to read.
As it is doing allocations on a non-standard way, let's add some
documentation while shutting up the false positive.

smatch warns that the RC query code could go past the array size:
drivers/media/usb/dvb-usb-v2/rtl28xxu.c:1757 rtl2832u_rc_query() error: buffer overflow 'buf' 128 <= 130
drivers/media/usb/dvb-usb-v2/rtl28xxu.c:1758 rtl2832u_rc_query() error: buffer overflow 'buf' 128 <= 130
The driver logic gets the length of the IR RX buffer with:
ret = rtl28xxu_rd_reg(d, IR_RX_BC, &buf[0]);
...
len = buf[0];
In thesis, this could range between 0 and 255 [1].
While this should never happen in practice, due to hardware limits,
smatch is right when it complains about that, as there's nothing at
the logic that would prevent it. So, if for whatever reason, buf[0]
gets filled by rtl28xx read functions with a value bigger than 128,
it will go past the array.
So, add an explicit check.
[1] I've no idea why smatch thinks that the maximum value is 130.
I double-checked the code several times. Was unable to find any
reason for assuming 130. Perhaps smatch is not properly parsing
u8 here?

pull-request: bpf-next 2018-08-07
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add cgroup local storage for BPF programs, which provides a fast
accessible memory for storing various per-cgroup data like number
of transmitted packets, etc, from Roman.
2) Support bpf_get_socket_cookie() BPF helper in several more program
types that have a full socket available, from Andrey.
3) Significantly improve the performance of perf events which are
reported from BPF offload. Also convert a couple of BPF AF_XDP
samples overto use libbpf, both from Jakub.
4) seg6local LWT provides the End.DT6 action, which allows to
decapsulate an outer IPv6 header containing a Segment Routing Header.
Adds this action now to the seg6local BPF interface, from Mathieu.
5) Do not mark dst register as unbounded in MOV64 instruction when
both src and dst register are the same, from Arthur.
6) Define u_smp_rmb() and u_smp_wmb() to their respective barrier
instructions on arm64 for the AF_XDP sample code, from Brian.
7) Convert the tcp_client.py and tcp_server.py BPF selftest scripts
over from Python 2 to Python 3, from Jeremy.
8) Enable BTF build flags to the BPF sample code Makefile, from Taeung.
9) Remove an unnecessary rcu_read_lock() in run_lwt_bpf(), from Taehee.
10) Several improvements to the README.rst from the BPF documentation
to make it more consistent with RST format, from Tobin.
11) Replace all occurrences of strerror() by calls to strerror_r()
in libbpf and fix a FORTIFY_SOURCE build error along with it,
from Thomas.
12) Fix a bug in bpftool's get_btf() function to correctly propagate
an error via PTR_ERR(), from Yue.

The kernel provides a __packed definition to abstract away from the
compiler specific attributes tag.
Convert all packed structures in VSP1 to use it.
The GCC documentation [0] describes this attribute as "the structure or
union is placed to minimize the memory required".
The Keil compiler documentation at [1] warns that the use of this
attribute can cause a performance penalty in the event that the compiler
can not deduce the allignment of each field.
Careful examination of the object code generated both with and without
this attribute shows that these structures are accessed identically and
are not affected by any performance penalty. The structures are
correctly aligned and padded to match the needs of the hardware already.
This patch does not serve to make a decision as to the use of the
attribute, but purely to clean up the code to use the kernel defined
abstraction as per [2].

Right now, satellite frontend drivers specify frequencies in kHz,
while terrestrial/cable ones specify in Hz. That's confusing
for developers.
However, the main problem is that universal frontends capable
of handling both satellite and non-satelite delivery systems
are appearing. We end by needing to hack the drivers in

So, convert everything to specify frontend frequencies in Hz.

Split off all code specific to the MaxSX8 cards to a separate ddbridge-sx8
module and hook it up in the Makefile. This also adds evaluation of the
mci_type to allow for using different attach handling for different cards.
As different cards can implement things differently (ie. support differing
frontend_ops, and have different base structs being put ontop of the
common mci_base struct), this introduces the mci_cfg struct which is
initially used to hold a few specifics to the -sx8 submodule. While at it,
the handling of the i/q mode is adjusted slightly. Besides this and
handling mci_base and sx8_base struct pointers where needed, all code
is copied unmodified from ddbridge-mci.c.

In demod_attach_stv0910(), the LNBH25 IC is being blindly attached and,
if the result is bad, blindly attached on another possible I2C address.
The LNBH25 uses it's set_voltage function to test for the IC and will
print an error to the kernel log on failure. Prevent this by probing
the possible I2C address and use this (and only this) to attach the
LNBH25 I2C driver. This also allows the stv0910 attach function to be
a bit cleaner.

The em28xx driver never touched the EM2874 register bits that control
the transport stream packet filters, leaving them at whatever default
the firmware has set. E.g. the Pinnacle 290e disables them by default,
while the Hauppauge WinTV dualHD enables discarding NULL packets by
default.
However, some applications require NULL packets, e.g. to determine the
load in DOCSIS segments, so discarding NULL packets is undesired for
such applications.
This patch simply extends the bit mask when starting or stopping the
transport stream packet capture, so that the filter bits are cleared.
It has been verified that this makes the Hauppauge WinTV dualHD pass
an unfiltered DVB-C stream including NULL packets, which it didn't
before.

This patch decomposes friio driver into sub drivers and
re-uses existing ones, thus reduces some code.
It adds some features to gl861,
to support the friio-specific init/config of the devices

The VSP uses a lock to protect the BRU and BRS assignment when
configuring pipelines. The lock is taken in vsp1_du_atomic_begin() and
released in vsp1_du_atomic_flush(), as well as taken and released in
vsp1_du_setup_lif(). This guards against multiple pipelines trying to
assign the same BRU and BRS at the same time.
The DRM framework calls the .atomic_begin() operations in a loop over
all CRTCs included in an atomic commit. On a VSPDL (the only VSP type
where this matters), a single VSP instance handles two CRTCs, with a
single lock. This results in a deadlock when the .atomic_begin()
operation is called on the second CRTC.
The DRM framework serializes atomic commits that affect the same CRTCs,
but doesn't know about two CRTCs sharing the same VSPDL. Two commits
affecting the VSPDL LIF0 and LIF1 respectively can thus race each other,
hence the need for a lock.
This could be fixed on the DRM side by forcing serialization of commits
affecting CRTCs backed by the same VSPDL, but that would negatively
affect performances, as the locking is only needed when the BRU and BRS
need to be reassigned, which is an uncommon case.
The lock protects the whole .atomic_begin() to .atomic_flush() sequence.
The only operation that can occur in-between is vsp1_du_atomic_update(),
which doesn't touch the BRU and BRS, and thus doesn't need to be
protected by the lock. We can thus only take the lock around the
pipeline setup calls in vsp1_du_atomic_flush(), which fixes the
deadlock.

Look up of buffers in s5p_mfc_handle_frame_new, s5p_mfc_handle_frame_copy_time
functions is not working properly for DMA addresses above 2 GiB. As a result
flags and timestamp of returned buffers are not set correctly and it breaks
operation of GStreamer/OMX plugins which rely on the CAPTURE buffer queue
flags.
Due to improper return type of the get_dec_y_adr, get_dspl_y_adr callbacks
and sign bit extension these callbacks return incorrect address values,
e.g. 0xfffffffffefc0000 instead of 0x00000000fefc0000. Then the statement:
"if (vb2_dma_contig_plane_dma_addr(&dst_buf->b->vb2_buf, 0) == dec_y_addr)"
is always false, which breaks looking up capture queue buffers.
To ensure proper matching by address u32 type is used for the DMA
addresses. This should work on all related SoCs, since the MFC DMA
address width is not larger than 32-bit.
Changes done in this patch are minimal as there is a larger patch series
pending refactoring the whole driver.

Commit 34dbb848d5 ("media: mem2mem: Remove excessive try_run call")
removed a redundant call to v4l2_m2m_try_run but instead introduced
a bug. Consider the following case:
1) Context A schedules, queues and runs job A.
2) While the m2m device is running, context B schedules
and queues job B. Job B cannot run, because it has to
wait for job A.
3) Job A completes, calls v4l2_m2m_job_finish, and tries
to queue a job for context A, but since the context is
empty it won't do anything.
In this scenario, queued job B will never run. Fix this by calling
v4l2_m2m_try_run from v4l2_m2m_try_schedule.
While here, add more documentation to these functions.

Currently this driver does not support cropping. The supported modes
are the following, all capturing the entire area:
- 3840x2160, 1:1 binning (native sensor resolution)
- 1920x1080, 2:1 binning
- 1280x720, 3:1 binning
The VIDIOC_SUBDEV_S_FMT ioctl chooses among these 3 configurations the
one that matches the requested format.
Add cropping support via VIDIOC_SUBDEV_S_SELECTION: with target
V4L2_SEL_TGT_CROP to choose the captured area, with
V4L2_SEL_TGT_COMPOSE to choose the output resolution.
To maintain backward compatibility we also allow setting the compose
format via VIDIOC_SUBDEV_S_FMT. To obtain this, compose rect and
output format are computed in the common helper function
__imx274_change_compose(), which sets both to the same width/height
values.
Cropping also calls __imx274_change_compose() whenever cropping rect
size changes in order to reset the compose rect (and output format
size) for 1:1 binning.
Also rename enum imx274_mode to imx274_binning (and its values from
IMX274_MODE_BINNING_* to IMX274_BINNING_*). Without cropping, the two
naming are equivalent. With cropping, the resolution could be
different, e.g. using 2:1 binning mode to crop 1200x960 and output a
600x480 format. Using binning in the names avoids any
misunderstanding. For the same reason, replace the 'size' field in
struct imx274_frmfmt with 'bin_ratio'.

Addresses the following, which introduced a regression itself:
Commit 509f89652f ("media: em28xx: fix a regression with HVR-950")
The regression fix breaks dual transport stream support. Currently,
when a tuner starts streaming it sets alt mode on the USB interface.
The problem is, in a dual tuner model, both tuners share the same
USB interface, so when the second tuner becomes active and sets alt
mode on the interface it kills streaming on the other port.
This patch addresses the regression by only setting alt mode
on the USB interface during em28xx_start_streaming, if the
device is not a dual tuner model. This allows all older and
single tuner devices to explicitly set alt mode during stream
startup. Testers report both isoc and bulk DualHD models work
correctly with the alt mode set only once, in em28xx_dvb_init.

This is implementing multi-stream decoder support. The multi-stream
will be used to enable/disable the primary/secondary decoder
outputs. Depending on formats on both decoder outputs we could
implement downscale, dithering and supporting UBWC (universal
bandwidth compression) formats. The UBWC compressed raw format is
used to optimize interconnect bandwidth for bigger resolutions
like 4K and hence we will get some power-saving benefits as well.
Both decoder outputs are distinguished by buffer_type field in
the HFI packets. For example HFI_BUFFER_OUTPUT is the buffer type
for primary decoder output and HFI_BUFFER_OUTPUT2 is for secondary
decoder output.
Starting from Venus 4xx the DPB buffers format must be UBWC, so
the multi-stream becomes mandatory for this Venus version. That
means that we need to allocate internally in the driver a set of
DPB buffers (with UBWC NV12 format) and give them to the firmware.
The other decoder output (we called it OPB) format will be NV12
linear format and with the same resolution (or smaller in case
the user wants to downscale).
The DPB buffers are used for decoder reference frames and those
have to be in a specific format (UBWC). So one decoder output is
used to fill those reference buffers while the other output is
used to fill the userspace buffers with the user requested format.

As per the documentation, job_abort is not required
to wait until the current job finishes. It is redundant
to do so, as the core will perform the wait operation.
Remove the wait infrastructure completely.

There is no way to control the standard of subdevices which are part of
a media device. The ioctls which exists all target video devices
explicitly and the idea is that the video device should talk to the
subdevice. For subdevices part of a media graph this is not possible and
the standard must be controlled on the subdev device directly.
Add four new ioctls to be able to directly interact with subdevices and
control the video standard; VIDIOC_SUBDEV_ENUMSTD, VIDIOC_SUBDEV_G_STD,
VIDIOC_SUBDEV_S_STD and VIDIOC_SUBDEV_QUERYSTD.

A lot of sensor drivers are labelled as "sensor-level" drivers. That's
odd and somewhat confusing as the term isn't used elsewhere: these are
just sensor drivers. Call them such.

The external clock frequency was set to 23.88MHz by mistake
because of a platform which cannot get closer to 24MHz.
The supported by the driver external clock is 24MHz so
set it correctly and also fix the values of the pixel
clock and link clock.
However allow 1% tolerance to the external clock as this
difference is small enough to be insignificant.

Convert all users of struct acpi_reference_args to more generic
fwnode_reference_args. This will
1) avoid an ACPI specific references to device nodes with integer
arguments as well as
2) allow making references to nodes other than device nodes in ACPI.
As a by-product, convert the fwnode interger arguments to u64. The
arguments were 64-bit integers on ACPI but the fwnode arguments were
just 32-bit.

The ChromeOS Embedded Controller can expose a CEC bus, this patch add the
driver for such feature of the Embedded Controller.
This driver is part of the cros-ec MFD and will be add as a sub-device when
the feature bit is exposed by the EC.
The controller will only handle a single logical address and handles
all the messages retries and will only expose Success or Error.
The controller will be tied to the HDMI CEC notifier by using the platform
DMI Data and the i915 device name and connector name.

In non device-tree world, we can need to get the notifier by the driver
name directly and eventually defer probe if not yet created.
This patch adds a variant of the get function by using the device name
instead and will not create a notifier if not yet created.
But the i915 driver exposes at least 2 HDMI connectors, this patch also
adds the possibility to add a connector name tied to the notifier device
to form a tuple and associate different CEC controllers for each HDMI
connectors.
