This patch fixes regression introduced in commit 6319d6a002beb26631
'[media] fimc-lite: Add ISP FIFO output support'.
In case of a configuration where video is captured at the video node
exposed by the FIMC-LITE driver there is a following video pipeline:
sensor -> MIPI-CSIS.n -> FIMC-LITE.n subdev -> FIMC-LITE.n video node
In this situation s_stream() handler of the FIMC-LITE.n is called
back from within VIDIOC_STREAMON/OFF ioctl of the FIMC-LITE.n video
node, through vb2_stream_on/off(), start/stop_streaming and
fimc_pipeline_call(set_stream). The fimc->lock mutex is already held
then, before invoking vidioc_streamon/off. So it must not be taken
again in the s_stream() callback in this case, to avoid a deadlock.
This patch makes fimc->out_path atomic_t so the mutex don't need
to be taken in the FIMC-LITE subdev s_stream() callback in the DMA
output case.

Modified the G2D driver (which initially supported only H/W Rev.3)
to support H/W Rev.4.1 present on Exynos4x12 and Exynos52x0 SOCs.
- Set the SRC and DST type to 'memory' instead of using reset values.
- FIMG2D v4.1 H/W uses different logic for stretching(scaling).
- Use CACHECTL_REG only with FIMG2D v3.

Make sure bytesperline for Cb, Cr planes for V4L2_PIX_FMT_YUV420M
format is half of the Y plane value, rather than having same
bytesperline for all planes.
While at it, simplify the bytesperline parameter handling by
storing it when image format is set and returning those values
when getting the format, instead of recalculating bytesperline
from intermediate parameters.

This patch fixes a bug which causes all histogram regions to start in the

values which share a 32 bit register. The bug is due to the region end

The preview engine includes filters that consume columns and lines as
part of their operation, thus resulting in a cropped image. To allow
turning those filters on/off during streaming without affecting the
output image size, the driver adds additional cropping to make the total
number of cropped columns and lines constant regardless of which filters
are enabled.
This process needlessly includes the CFA filter, as whether the filter
is enabled only depends on the sink pad format, which can't change
during streaming.
Exclude the CFA filter from the preview engine margins.

Walking rbtree while it's modified is a Bad Idea(tm); besides,
the result of find_vma() can be freed just as it's getting returned
to caller. Fortunately, it's easy to fix - just take ->mmap_sem a bit
earlier (and don't bother with find_vma() at all if virtp >= PAGE_OFFSET -
in that case we don't even look at its result).
While we are at it, what prevents VIDIOC_PREPARE_BUF calling
v4l_prepare_buf() -> (e.g) vb2_ioctl_prepare_buf() -> vb2_prepare_buf() ->
__buf_prepare() -> __qbuf_userptr() -> vb2_vmalloc_get_userptr() -> find_vma(),
AFAICS without having taken ->mmap_sem anywhere in process? The code flow
is bloody convoluted and depends on a bunch of things done by initialization,
so I certainly might've missed something...

This patch patch eliminates potential AB-BA deadlock when one process calls
open(), or VIDIOC_S/TRY_FMT ioctl on the FIMC capture video node, while
other thread is reconfiguring media links via media device node:
/dev/video? open() /dev/media? MEDIA_IOC_SETUP_LINK ioctl
mutex_lock(video_lock) mutex_lock(graph_lock)
fimc_pipeline_open() fimc_md_link_notify()
mutex_lock(graph_lock) mutex_lock(video_lock)
... ...
The deadlock is avoided by always taking the graph mutex first in video
node open() or an ioctl, before the video lock is acquired. Reversed
order seems impossible, since media device driver's link_notify callback
is called with media graph mutex already held.
To ensure proper locking order VIDIOC_S_FMT and VIDIOC_TRY_FMT ioctls are
not serialized in the v4l2-core and the driver takes care of it itself.

Currently devm_regulator_bulk_get() is called by soc-camera during host
driver probing, but regulators are attached to the camera platform
device, that is staying, independent whether the host probed successfully
or not. This can lead to repeated regulator requesting, if the host
driver is re-probed. Move the call to platform device probing to avoid
this.

The recently introduced host_lock causes lockdep warnings, besides, list
enumeration in scan_add_host() must be protected by holdint the list_lock.
OTOH, holding .video_lock in soc_camera_open() isn't enough to protect
the host during its building of the pipeline, because .video_lock is per
soc-camera device. If, e.g. more than one sensor can be attached to a host
and the user tries to open both device nodes simultaneously, host's .add()
method can be called simultaneously for both sensors. Fix these problems
by holding list_lock instead of .host_lock in scan_add_host() and taking
it shortly at the beginning of soc_camera_open(), and using .host_lock to
protect host's .add() and .remove() operations only.

I was testing my video-over-ethernet subsystem recently, and vivi
seemed to be perfect video source for testing when one don't have lots
of capture boards and cameras. Only its framerate was hardcoded to
NTSC's 30fps, while in my country we usually use PAL (25 fps) and I
needed that to precisely simulate bandwidth.
That's why here is this patch with ->enum_frameintervals() and
->{g,s}_parm() implemented as suggested by Hans Verkuil which passes
v4l2-compliance and manual testing through v4l2-ctl -P / -p <fps>.
Regarding newly introduced __get_format(u32 pixelformat) I decided not
to convert original get_format() to operate on fourcc codes, since >= 3
places in driver need to deal with v4l2_format and otherwise it won't be
handy.

I've noticed that vivi takes a lot of CPU to produce its frames.
For example for 8 devices and 8 simple programs running, where each
captures YUY2 640x480 and displays it to X via SDL, profile timing is as
follows:
# cmdline : /home/kirr/local/perf/bin/perf record -g -a sleep 20
# Samples: 82K of event 'cycles'
# Event count (approx.): 31551930117

8.35% vivi-* [vivi] [k] gen_text.constprop.6
5.06% Xorg [unknown] [.] 0xa73015f8
2.32% rawv [vivi] [k] gen_twopix
1.22% rawv [vivi] [k] precalculate_line
1.20% vivi-* [vivi] [k] vivi_fillbuff
(rawv is display program, vivi-* is a combination of vivi-000 through vivi-007)
so a lot of time is spent in gen_twopix() which as the follwing
call-graph profile shows ...
49.48% vivi-* [vivi] [k] gen_twopix
|
--- gen_twopix
|
|--96.30%-- gen_text.constprop.6
| vivi_fillbuff
| vivi_thread
| kthread
| ret_from_kernel_thread
|
--3.70%-- vivi_fillbuff
vivi_thread
kthread
ret_from_kernel_thread
... is called mostly from gen_text().
If we'll look at gen_text(), in the inner loop, we'll see
if (chr & (1 << (7 - i)))
gen_twopix(dev, pos + j * dev->pixelsize, WHITE, (x+y) & 1);
else
gen_twopix(dev, pos + j * dev->pixelsize, TEXT_BLACK, (x+y) & 1);
which calls gen_twopix() for every character pixel, and that is very
expensive, because gen_twopix() branches several times.
Now, let's note, that we operate on only two colors - WHITE and
TEXT_BLACK, and that pixel for that colors could be precomputed and
gen_twopix() moved out of the inner loop. Also note, that for black
and white colors even/odd does not make a difference for all supported
pixel formats, so we could stop doing that `odd` gen_twopix() parameter
game.
So the first thing we are doing here is
1) moving gen_twopix() calls out of gen_text() into vivi_fillbuff(),
to pregenerate black and white colors, just before printing
starts.
what we have next is that gen_text's font rendering loop, even with
gen_twopix() calls moved out, was inefficient and branchy, so let's
2) rewrite gen_text() loop so it uses less variables + unroll char
horizontal-rendering loop + instantiate 3 code paths for pixelsizes 2,3
and 4 so that in all inner loops we don't have to branch or make
indirections (*).
Done all above reworks, for gen_text() we get nice, non-branchy
streamlined code (showing loop for pixelsize=2):

(*) for RGB24 rendering I've introduced x24, which could be thought as

Fortunately, in C struct assignment is builtin and that's all we

The vpbe driver can handle different platforms DM644X, DM36X and
DM355. To differentiate between this platforms venc_type/vpbe_type
was passed as part of platform data which was incorrect. The correct
way to differentiate to handle this case is by passing different
platform names.
This patch creates platform_device_id[] array supporting different
platforms and assigns id_table to the platform driver, and finally
in the probe gets the actual device by using platform_get_device_id()
and gets the appropriate driver data for that platform.
Taking this approach will also make the DT transition easier.

is used as a glue logic between FIMC-IS and MIPI-CSIS or an image
sensor. The second source media pad will be linked to the FIMC-LITE
video node.
For proper configuration the attached image sensor/video encoder
properties are needed, like video bus type, signal polarities, etc.
For this purpose there is a small routine added that walks the
pipeline and returns the sensor subdev.

Setting FIMC_REG_CITRGFMT_FLIP_X_MIRROR bit causes X-axis image
flip (vertical flip) and thus it corresponds to V4L2_CID_VFLIP.
Likewise, setting FIMC_REG_CITRGFMT_FLIP_Y_MIRROR bit causes Y-axis
image flip (horizontal flip) and thus it corresponds to V4L2_CID_HFLIP.
Currently the driver does X-axis flip when V4L2_CID_HFLIP is set and
Y-axis flip for V4L2_CID_VFLIP. Fix this incorrect assignment by setting
proper FIMC_REG_CITRGFMT register bits for ctx->hflip and ctx->vflip.

Explicit checks for the JPEG pixel format in soc_mbus_bytes_per_line() and
soc_mbus_image_size() are superfluous, because also without them these
functions will perform correctly. The former will return 0 based on
packing == SOC_MBUS_PACKING_VARIABLE and the latter will simply multiply
the user-provided line length by the image height to obtain a frame buffer
size estimate. The original version of the "media: soc_camera: don't clear

of the subdevices returns -EINVAL if the type is not set properly. Here the

Based on earlier discussions[1] we attempted to find a suitable
location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP:
DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion
to dmaengine is complete.
Unfortunately that was before I was able to try to test compile
of the ARM multiplatform builds for omap2+, and the end result
was not very good.
So I'm creating yet another all over the place patch to cut the
last dependency for building omap2+ for ARM multiplatform. After
this, we have finally removed the driver dependencies to the
arch/arm code, except for few drivers that are being worked on.
The other option was to make the <plat-omap/dma-omap.h> path
to work, but we'd have to add some new header directory to for
multiplatform builds.
Or we would have to manually include arch/arm/plat-omap/include
again from arch/arm/Makefile for omap2+.
Neither of these alternatives sound appealing as they will
likely lead addition of various other headers exposed to the
drivers, which we want to avoid for the multiplatform kernels.
Since we already have a minimal include/linux/omap-dma.h,
let's just use that instead and add a note to it to not
use the custom omap DMA functions any longer where possible.
Note that converting omap DMA to dmaengine depends on
dmaengine supporting automatically incrementing the FIFO
address at the device end, and converting all the remaining
legacy drivers. So it's going to be few more merge windows.

cpu_is_* class functions create a dependency to OMAP platform code.
omapdss driver, which omap_vout uses, exposes a function to get the
version of the DSS hardware.
To remove the dependency to OMAP platform code this patch changes
omap_vout to use the omapdss version. For most of the checks, the ones
dealing with DSS differences, this is actually more correct than using
cpu_is_* functions. For the check whether VRFB is available or not this
is not really correct, but still works fine.

This patch adds V4L2 driver for Samsung S3C24XX/S3C64XX SoC series
camera interface. The driver exposes a subdev device node for CAMIF
pixel resolution and crop control and two video capture nodes - for
the "codec" and "preview" data paths. It has been tested on Mini2440
(s3c2440) and Mini6410 (s3c6410) board with gstreamer and mplayer.

Looks like the iommu framework does not have generic functions
exported for all the needs yet. The hardware specific functions
are defined in files like intel-iommu.h and amd-iommu.h. Follow
the same standard for omap-iommu.h.
This is needed because we are removing plat and mach includes
for ARM common zImage support. Further work should continue
in the iommu framework context as only pure platform data will
be communicated from arch/arm/*omap*/* code to the iommu
framework.

Since mx27 transitioned to the commmon clock framework in 3.5, the correct way
to acquire the csi clock is to get csi_ahb and csi_per clocks separately.
By not doing so the camera sensor does not probe correctly:
soc-camera-pdrv soc-camera-pdrv.0: Probing soc-camera-pdrv.0
mx2-camera mx2-camera.0: Camera driver attached to camera 0
ov2640 0-0030: Product ID error fb:fb
mx2-camera mx2-camera.0: Camera driver detached from camera 0
mx2-camera mx2-camera.0: MX2 Camera (CSI) driver probed, clock frequency: 66500000

The omap_vout driver tries to set the DSS overlay_info using set_overlay_info()
when the physical address for the overlay is still not configured. This happens
in omap_vout_probe() and vidioc_s_fmt_vid_out().
The calls to omapvid_init(which internally calls set_overlay_info()) are removed
from these functions. They don't need to be called as the omap_vout_device
struct anyway maintains the overlay related changes made. Also, remove the
explicit call to set_overlay_info() in vidioc_streamon(), this was used to set
the paddr, this isn't needed as omapvid_init() does the same thing later.
These changes are required as the DSS2 driver since 3.3 kernel doesn't let you
set the overlay info with paddr as 0.

Pull second set of media updates from Mauro Carvalho Chehab:
"Despite its size, most of the stuff here is trivial. This series
contains:
- s5p-mfc: additions at the driver and at the core to support H.264
hardware codec;
- Some improvements at s5p and davinci embedded drivers;
- Some V4L2 compliance fixes applied on a few drivers;
- Several random trivial patches, including several fixes and a few
new board support additions;
Notes:
1) Some Exynos media patches were dependent on some -arm fixes that
got merged on changeset 782cd9e. That's why this pull request is
based that changeset.
2) As promised, I reviewed the pending VB2 DMABUF series.
While setting a test environment, it was noticed that the upstream
support for Samsung Exynos 4 boards (smdk310 and Origen) are
broken upstream, likely due to regressions: both defconfigs are
wrong and regulator settings for both boards are broken. That,
allied with some bug at the dummy regulator driver, causes OOPSes
during boot time.
Long story short: even fixing the above, the proposed patches
OOPSed when running the DMABUF test. Not sure yet if the OOPSes
are due to some other undetected regressions, or due to some bug
on the patches.
Due to the above, DMABUF patches for vb2 got NACKed for 3.7."

A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA,
currently it lost original meaning but still has some effects:
| effect | alternative flags
-+------------------------+---------------------------------------------
1| account as reserved_vm | VM_IO
2| skip in core dump | VM_IO, VM_DONTDUMP
3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP
4| do not mlock | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP
This patch removes reserved_vm counter from mm_struct. Seems like nobody
cares about it, it does not exported into userspace directly, it only
reduces total_vm showed in proc.
Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP.
remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP.
remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.

Pull media updates from Mauro Carvalho Chehab:
"The first part of the media updates for Kernel 3.7.
This series contain:
- A major tree renaming patch series: now, drivers are organized
internally by their used bus, instead of by V4L2 and/or DVB API,
providing a cleaner driver location for hybrid drivers that
implement both APIs, and allowing to cleanup the Kconfig items and
make them more intuitive for the end user;
- Media Kernel developers are typically very lazy with their duties
of keeping the MAINTAINERS entries for their drivers updated. As
now the tree is more organized, we're doing an effort to add/update
those entries for the drivers that aren't currently orphan;
- Several DVB USB drivers got moved to a new DVB USB v2 core; the new
core fixes several bugs (as the existing one that got bitroted).
Now, suspend/resume finally started to work fine (at least with
some devices - we should expect more work with regards to it);
- added multistream support for DVB-T2, and unified the API for
DVB-S2 and ISDB-S. Backward binary support is preserved;
- as usual, a few new drivers, some V4L2 core improvements and lots
of drivers improvements and fixes.
There are some points to notice on this series:
1) you should expect a trivial merge conflict on your tree, with the
removal of Documentation/feature-removal-schedule.txt: this series
would be adding two additional entries there. I opted to not
rebase it due to this recent change;
2) With regards to the PCTV 520e udev-related breakage, I opted to
fix it in a way that the patches can be backported to 3.5 even
without your firmware fix patch. This way, Greg doesn't need to
rush backporting your patch (as there are still the firmware cache
and firmware path customization issues to be addressed there).
I'll send later a patch (likely after the end of the merge window)
reverting the rest of the DRX-K async firmware request, fully
restoring its original behaviour to allow media drivers to
initialize everything serialized as before for 3.7 and upper.
3) I'm planning to work on this weekend to test the DMABUF patches
for V4L2. The patches are on my queue for several Kernel cycles,
but, up to now, there is/was no way to test the series locally.
I have some concerns about this particular changeset with regards
to security issues, and with regards to the replacement of the old
VIDIOC_OVERLAY ioctl's that is broken on modern systems, due to
GPU drivers change. The Overlay API allows direct PCI2PCI
transfers from a media capture card into the GPU framebuffer, but
its API is crappy. Also, the only existing X11 driver that
implements it requires a XV extension that is not available
anymore on modern drivers. The DMABUF can do the same thing, but
with it is promising to be a properly-designed API. If I can
successfully test this series and be happy with it, I should be
asking you to pull them next week."

The V4L2_PIX_FMT_S5C_YUYV_JPG image formats consists of 2 planes, the
first containing interleaved JPEG/YUYV data and the second containing
meta data describing the interleaving method.
The image data is transferred with MIPI-CSI "User Defined Byte-Based
Data 1" type and is captured to memory by FIMC DMA engine.
The meta data is transferred using MIPI-CSI2 "Embedded 8-bit non Image
Data" and it is captured in the MIPI-CSI slave device and copied to
the bridge provided buffer.
To make sure the size of allocated buffers is correct for the subdevs
configuration when VIDIOC_STREAMON ioctl is invoked, an additional
check is added at the video pipeline validation function.
Flag FMT_FLAGS_COMPRESSED indicates the buffer size must be retrieved
from a sensor subdev.

MIPI-CSI has internal memory mapped buffers for the frame embedded
(non-image) data. There are two buffers, for even and odd frames which
need to be saved after an interrupt is raised. The packet data buffers
size is 4 KiB and there is no status register in the hardware where the
actual non-image data size can be read from. Hence the driver copies
whole packet data buffer into a buffer provided by the FIMC driver.
This will form a separate plane in the user buffer.
When FIMC DMA engine is stopped by the driver due the to user space
not keeping up with buffer de-queuing the MIPI-CSIS will still run,
however it must discard data which is not captured by FIMC. Which
frames are actually capture by MIPI-CSIS is determined by means of
the s_tx_buffer subdev callback. When it is not called after a single
embedded data frame has been captured and copied and before next
embedded data frame interrupt occurrs, subsequent embedded data frames
will be dropped.

In order to reuse the FIMC-LITE module on Exynos4 and Exynos5
SoC introduce a set of callbacks for the media pipeline control
from within FIMC/FIMC-LITE video node. It lets us avoid symbol
dependencies between FIMC-LITE and the whole media device driver,
which simplifies the initialization sequences and doesn't
introduce issues preventing common kernel image for exynos4 and
exynos5 SoCs.
This patch also corrects following build errors:
drivers/built-in.o: In function `buffer_queue':
drivers/media/video/s5p-fimc/fimc-lite.c:414: undefined reference
to `fimc_pipeline_s_stream'

This fixes a failure in vb2_qbuf in user pointer mode where
__qbuf_userptr checks if the buffer queued by userspace is large
enough. The failure would happen if coda_queue_setup was called
with empty fmt (and thus set the expected buffer size to the maximum
resolution), and userspace queues buffers of smaller size -
corresponding to the negotiated dimensions - were queued.
Explicitly setting sizeimage to the value negotiated via s_fmt
fixes the issue.

Some codecs running on CODA need internal framebuffers for reference and
reconstructed frames. Allocate them separately, and do not use the input
vb2_buffers: those will be handed off to userspace regularly, and there
is no way to signal to the CODA which of the registered framebuffers are
off limits. As a consequence, userspace is now free to choose the number
of v4l2 buffers.
This patch also includes the code to set up the parameter buffer for
CODA7 and above with 64-bit AXI bus width.

Instead of having 3 options to allow customizing the media
sub-drivers (tuners, I2C drivers, frontends), merge all of
them into just one.
That simplifies the life for users, as they can just keep
this untouched.
Life for developers is also simpler, as there's now just
one Kconfig item to remember, for the ancillary sub-drivers
providing supports for chips that could change from one
board design to another.

- get rid of ridden V4L2_COMMON symbol
This symbol is not needed anymore; it can be folded with V4L2
one, simplifying the Kconfig a little bit;

On a few places, := were using instead of +=, causing drivers to
not compile.
While here, standardize the usage of += on all cases where multiple
lines are needed, and for obj-y/obj-m targets, and := when just one
line is needed, on <module>-obj rules.

In JPEG mode, the size of image is variable due to different JPEG compression
rate. We only can get the pix->sizeimage from the user.
If we clear pix->sizeimage in soc_camera_try_fmt() then we will get it from:
ret = soc_mbus_image_size(xlate->host_fmt, pix->bytesperline,
pix->height);
if (ret < 0)
return ret;
pix->sizeimage = max_t(u32, pix->sizeimage, ret);
In general, this sizeimage will be larger than the actul JPEG image size.
But vb2 will check the buffer and size of image in __qbuf_userptr():
/* Check if the provided plane buffer is large enough */
if (planes[plane].length < q->plane_sizes[plane])
So we shouldn't clear the pix->sizeimage and also shouldn't re-calculate
the pix->sizeimage in soc_mbus_image_size() in JPEG mode
We also shouldn't re-calculate pix->bytesperline:
ret = soc_mbus_bytes_per_line(pix->width, xlate->host_fmt);
if (ret < 0)
return ret;
pix->bytesperline = max_t(u32, pix->bytesperline, ret);
pix->bytesperline also should be set by the user or by the driver's
try_fmt() implementation.

This patch checks the state of the buffer when calling .buf_init() method.
This is needed for the USERPTR buffer type, because in that case
.buf_init() is called every time a buffer is queued, and not only once
during the preparation stage, like in the MMAP case. Without this check
buffers get initialised repeatedly, which also leads to the allocation
of new DMA descriptors, of which there is only a final relatively small
number available. Both MMAP and USERPTR methods were successfully tested.

Using devm_kzalloc simplifies the code and ensures that the use of
devm_request_irq is safe. When kzalloc and kfree were used, the interrupt
could be triggered after the handler's data argument had been freed.
This also introduces some missing initializations of the return variable
ret, and uses devm_request_and_ioremap instead of the combination of
devm_request_mem_region and devm_ioremap.
The problem of a free after a devm_request_irq was found using the
following semantic match (http://coccinelle.lip6.fr/)
// <smpl>
@r exists@
expression e1,e2,x,a,b,c,d;

Several client drivers access the hardware at probe time, for instance
to read the probe chip ID. Such chips need to be powered up when being
probed.
soc-camera handles this by powering chips up in the soc-camera probe
implementation. However, this will break with non soc-camera hosts that
don't perform the same operations.
Fix the problem by pushing the power up/down from the soc-camera core
down to individual drivers on a needs basis.

Instead of forcing all soc-camera drivers to go through the mid-layer to
handle power management, create soc_camera_power_[on|off]() functions
that can be called from the subdev .s_power() operation to manage
regulators and platform-specific power handling. This allows non
soc-camera hosts to use soc-camera-aware clients.

Powering off a device is a "best effort" task: failure to execute one of
the steps should not prevent the next steps to be executed. For
instance, an I2C communication error when putting the chip in stand-by
mode should not prevent the more agressive next step of turning the
chip's power supply off.
