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.

Using bulk mode allows more than one webcam, as the maximum fps
is low at 640x480 resolution. So, prefer it, if the device is
a webcam.
Tested with Silvercrest 1.3 Mpixel webcam (em2710) on both bulk and isoc
modes.
Tested analog with HVR-950 model 65201/A1C0 (em2883), where only ISOC
endpoints are available for both DVB and Analog.
Tested on Hauppauge WinTV USB 2 (em2840) on both bulk and isoc modes.
It should be noticed that enabling bulk mode by default with TV boards
is a bad idea; what happens is that, while with ISOC the USB logic will
prevent the concurrent usage of two devices that spends more than 100%
of the USB2 traffic, it doesn't care with bulk transfers.
On my tests, I started two streams, one with a WinTV at 640x480x30fps
and the other one with a Silvercrest webcam at 640x480, on a lower fps)
both on bulk mode. One of the streams always silently failed.

USB urb processing (checks, data extraction) and frame data packet processing.
Move the latter to a separate function and call it from em28xx_urb_data_copy()

The em25xx, em2760, em2765 (and likely em277x) chip variants are using a
different frame data format, for which support will be added later with
another function.

[media] em28xx: move caching of pointer to vmalloc memory in videobuf to struct em28xx_buffer
In the current code em28xx_urb_data_copy() caches the pointer to the vmalloc
memory in videobuf locally.
The alternative would be to call videobuf_to_vmalloc() for each processed USB
data packet (isoc USB transfers => 64 times per URB) in the em28xx_copy_*()
functions.
With the next commits, the data processing code will be split into functions
for serveral reasons:
- em28xx_urb_data_copy() is generally way to long, making it less readable
- there is code duplication between VBI and video data processing
- support for em25xx data processing (uses a different header and frame
end signaling mechanism) will be added
This would require extensive usage of pointer-pointers, which usually makes the
code less readable and prone to bugs.
The better solution is to cache the pointer in struct em28xx_buffer.
This also improves consistency, because we already track the buffer fill count there.

[media] em28xx: refactor VBI data processing code in em28xx_urb_data_copy()
When a new frame header is detected in em28xx_urb_data_copy() and the data
packet contains both, VBI data and video data, the prevoius VBI buffer doesn't
get finished and is overwritten with the new VBI data.
This bug is not triggered with isochronous USB transfers, because the data
packetes are much smaller than the VBI data size.
But when using USB bulk transfers, the whole data of an URB is treated as
single packet, which is usually much larger then the VBI data size.
Refactor the VBI data processing code to fix this bug, but also to simplify the
code and make it similar to the video data processing code part (which allows
further code abstraction/unification in the future).

[media] em28xx: add support for RC6 mode 0 on devices that support it
Newer em28xx chipsets (em2874 and upper) are capable of supporting
RC6 codes, on both mode 0 (command mode, 16 bits payload size, similar
to RC5, also called "Philips mode") and mode 6a (OEM command mode,
with offers a few alternatives with regards to the payload size).
I don't have any mode 6a control ATM to test it, so, I opted to add
support only to mode 0.
After this patch, adding support to mode 6a should not be hard.
Tested with a Philips television remote controller.
[media] em28xx: add support for NEC proto variants on em2874 and upper
By disabling the NEC parity check, it is possible to handle all 3 NEC
protocol variants (32, 24 or 16 bits).
Change the driver in order to handle all of them.
Unfortunately, em2860/em2863 provide only 16 bits for the IR scancode,
even when NEC parity is disabled. So, this change should affect only
em2874 and newer devices, with provides up to 32 bits for the scancode.
Tested with one NEC-16, one NEC-24 and one RC5 IR.
[media] Autoselect more relevant frontends for EM28XX DVB stick
I noticed that the EM28XX DVB driver doesn't auto select all of the

missing as well.

[media] rc: Call rc_register_device before irq setup
This should fix a potential race condition, when the irq handler
triggers while rc_register_device is still setting up the rdev->raw
device.
This crash has not been observed in practice, but there should be a very
small window where it could occur. Since ir_raw_event_store_with_filter
checks if rdev->raw is not NULL before using it, this bug is not
triggered if the request_irq triggers a pending irq directly (since
rdev->raw will still be NULL then).
This commit was tested on nuvoton-cir only.
This fixes a problem in fintek-cir and nuvoton-cir where the
irq handler would trigger during module load before the rdev member was
set, causing a NULL pointer crash.
It seems this crash is very reproducible (just bombard the receiver with
IR signals during module load), probably because when request_irq is
called, any pending intterupt is handled immediately, before
request_irq returns and rdev can be set.
This same crash was supposed to be fixed by commit 9ef449c6b31bb6a8e6dedc24de475a3b8c79be20 ("[media] rc: Postpone ISR
registration"), but the crash was still observed on the nuvoton-cir
driver.
This commit was tested on nuvoton-cir only.
[media] rc: Make probe cleanup goto labels more verbose
Before, labels were simply numbered. Now, the labels are named after the
cleanup action they'll perform (first), based on how the winbond-cir
driver does it. This makes the code a bit more clear and makes changes
in the ordering of labels easier to review.
This change is applied only to the rc drivers that do significant
cleanup in their probe functions: ati-remote, ene-ir, fintek-cir,
gpio-ir-recv, ite-cir, nuvoton-cir.
This commit should not change any code, it just renames goto labels.

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

follows:

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_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
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.
