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):

i.e. gen_twopix() overhead dropped from 49% to 4% and gen_text() loops
from ~8% to ~4%, and overal cycles count dropped from 31551930117 to
16799780016 which is ~1.9x whole workload speedup.
(*) for RGB24 rendering I've introduced x24, which could be thought as
synthetic u24 for simplifying the code. That's done because for
memcpy used for conditional assignment, gcc generates suboptimal code
with more indirections.
Fortunately, in C struct assignment is builtin and that's all we
need from pixeltype for font rendering.

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.

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.

In case of clk_prepare failure, the function gsc_clk_get also prints
"failed to get clock" which is not correct. Hence move the error
messages to their respective blocks. While at it, also renamed the labels

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
pix->sizeimage in JPEG mode" patch was correct and my amendment, adding
these two checks was superfluous.

Video Engine Unit (VEU) is an IP block, found in multiple SuperH and ARM-
based sh-mobile and r-mobile SoCs, capable of processing video data. It
can perform colour-space conversion, scaling and several filtering
transformations. This patch adds an initial implementation of a mem2mem
V4L2 driver for VEU. So far only conversion from NV12 to RGB565 is
supported. Further functionality shall be added in the future.
This driver is based on a VEU vidix driver by Magnus Damm.

Note that we can now also remove the unused plat/cpu.h from

keep the platform code generic enough to have them all share one mach
directory. The new Broadcom platform is contributed by Christian Daudt.
Highbank has grown support for Calxeda's next generation of hardware,
ECX-2000.
clps711x has seen a lot of cleanup from Alexander Shiyan, and he's also

Beyond this there has been a bunch of work from a number of people on
converting more platforms to IRQ domains, pinctrl conversion, cleanup
and general feature enablement across most of the active platforms.

Merge tag 'headers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC Header cleanups from Olof Johansson:
"This is a collection of header file cleanups, mostly for OMAP and
AT91, that keeps moving the platforms in the direction of
multiplatform by removing the need for mach-dependent header files
used in drivers and other places."
Fix up mostly trivial conflicts as per Olof.

Sometimes VIDIOC_S_CROP ioctl doesn't work, soc-camera driver reports:

The VIDIOC_G_CROP documentation states that the type field needs to be
set to the respective buffer type when querying, so the check in .g_crop()
of the subdevices returns -EINVAL if the type is not set properly. Here the
uninitialized local variable 'current_crop' is passed to the .g_crop() and
this leads to the observed error. Initialize the type field of the local

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.

Use uninterruptible mutex_lock in the release() file op to make
sure all resources are properly freed when a process is being
terminated. Returning -ERESTARTSYS has no effect for a terminating
process and this may cause driver resources not to be released.

Use uninterruptible mutex_lock in the release() file op to make
sure all resources are properly freed when a process is being
terminated. Returning -ERESTARTSYS has no effect for a terminating
process and this caused driver resources not to be released. Not
releasing the buffer queue also prevented other drivers to free
memory, e.g. in MMAP -> USERPTR scenario.
This patch is required for stable kernels v3.6+.
