Mauro, you are joking.

How I ever could come to that from here?
http://patchwork.kernel.org/project/linux-media/list

I'm forced to read the source code.

There seems to be some serious utf8 bug too.

The above link uses the default patchwork filtering. By default it shows only
patches where there's an action required (e. g. New or Under Review patches).

To view a full list of the patches, you need to click at filters and select any.

You'll see all patches:
http://patchwork.kernel.org/project/linux-media/list/?state=*

In the specific case od Klaas, this is his patch:

http://patchwork.kernel.org/patch/14405/

I've received the notification here:

From: Patch from klaas de waal  
To: linuxtv-comm...@linuxtv.org
Cc: , Mauro Carvalho Chehab , klaas de waal 

Subject: [linuxtv-commits] [hg:v4l-dvb] tda827x: fix locking issues with DVB-C

Reply-To: klaas de waal via Mercurial 
Sender: linuxtv-commits-boun...@linuxtv.org

The patch number 11236 was added via Mauro Carvalho Chehab 
to http://linuxtv.org/hg/v4l-dvb master development tree.

Klaas should be received this also. Maybe some anti-spam filtering on his side?

You'll probably see this also at the linuxtv-commits archives.

The import scripts will try to preserve the original date of the sent email.

So, the date there is when the code were presented to public.

If the patch was received by patchwork, and "disappeared", all you need to do
is to click on filter and select a proper filter, like:

http://patchwork.kernel.org/project/linux-media/list/?submitter=klaas&state=*

This will present all patches authored by "klaas", and their state. Ah, if you
click on the patch, you'll see all the patch history, including the
sent/received emails. Even this email should be added there by patchwork ;)

Cheers,
Mauro

Hmm, how this could ever happen?

I'm not able to copy and paste this from evolution with even the
recommended preformatted option enabled. How I could ever submit any
further patches?

So I tried several editors and did still provide such BS.

The last time I remember to have seen such was in 2005 with SECAM L' and
it was going on over half a year.

   V4L2_FOCUS_MANUAL= 2,
   V4L2_FOCUS_NORMAL= 3,
   V4L2_FOCUS_LASTP= 3,
};

how about this usage? i wanna get some advice about FOCUS MODE.


V4L2_CID_FOCUS_AUTO is meant to change the auto-focus mode. Can you  
describe
FOCUS_MACRO and FOCUS_NORMAL in more details ? Are they auto-focus  
modes or

just focus presets ?



As far as I know, they represent focus lens movement range.
If you set to AF macro, focus lens scans near range first, so that  
focusing movement could finish earlier.







This seems more logical to me:

enum v4l2_focus_mode {
   V4L2_FOCUS_MANUAL = 0,
   V4L2_FOCUS_AUTO_NORMAL = 1,
   V4L2_FOCUS_AUTO_MACRO = 2,
};

At least this maps the current boolean values correctly. I'm not  
sure from

your decription what the fourth auto focus mode is supposed to be.


Does an auto-macro focus mode really exists ?



Sure, you can find in some digital camera or brand new high end camera  
phones.


By the way, sorry for answering instead of heungjun Kim. I work with  
him actually.

Is it OK?

Cheers,

Nate




But I think it might be better to have a separate control that  
allows you
to set the auto-focus mode. I can imagine that different devices  
might have

different auto-focus modes.

I've CC-ed Laurent since this is more his field than mine.


Regards,

Laurent Pinchart

I hadn't forgotten this, it was just taking rather longer than expected to put 
together a working build system for the documentation (In the end I concluded 
the quickest approach was a complete OS upgrade to get working versions of the 
docbook tools and config files).

What happened so far with this patches is quite funny,
for me some black hole seems to be involved.

Klaas did send them the first time, also directly to me, on Tue, 24 Mar
2009 23:14:11 +0100.

Now I can see you have pulled them in already on Wednesday.
http://linuxtv.org/hg/v4l-dvb/rev/5efa9fbc8a88

There is no trace anymore on patchwork visible to me.
http://patchwork.kernel.org/project/linux-media/list
So I don't know how you processed them.

Most confusing is, that Klaas obviously did not receive a mail
notification from linuxtv-commits that his patch came in.

Last message date: Fri Feb 15 19:45:02 CET 2008
Archived on: Fri Feb 15 19:45:04 CET 2008 

Is it broken or only the archive not up to date?

Why else he would have posted a second time on
Wed, 25 Mar 2009 21:53:02 +0100 not knowing anything about the status of
his patches, which made me believe I should try to help him?

The timestamp on your mercurial commit of them is
Wed Mar 25 20:53:02 2009 + (2 days ago)
That is the time when his second email arrived converted to Greenwich
time? Or how could you commit within the same second that mail arrived?

This is the time the patches have on both of his original mails.
--- a/linux/drivers/media/common/tuners/tda827x.c Tue Mar 24 21:12:47 2009 +
--- a/linux/drivers/media/common/tuners/tda827x.c Tue Mar 24 21:12:47 2009 +

How can I ever know when they were really added and if they went through
patchwork :)

I was just about to suggest Klaas should try again with [PATCH] in the
subject until they are listed at patchwork.

Cheers,
Hermann

You're right, I was thinking about N?meth's earlier patches for the same
things in uvcvideo.  This patch wasn't for gspca anyway, it was for the
v4l2 core, and Mauro's right it's not necessary as my patch series fixed
all these problems.

yes, ATTRS{} still matches. There are udev howtos around which suggest
ATTRS{} just matches one level up and not the entire path. I tried it but
had unfortunately a typo in the udev rule. Sorry for the noise.

Yes, gspca does use video_ioctl2. You're probably confused with uvcvideo, 
which doesn't use it.

[PATCH resend] DVB: firedtv: FireDTV S2 problems with tuning solved

2009-03-27 Thread Stefan Richter
This came in via linux1394-devel.  If there are no objections, I'll
include it in my pull request to Linus which I want to send in a few
hours.  It's also good to send to stable.


Date: Thu, Mar 26, 2009 22:36:52 +0100 (CET)
From: Beat Michel Liechti 
Subject: DVB: firedtv: FireDTV S2 problems with tuning solved

Signed-off-by: Beat Michel Liechti 

Tuning was broken on FireDTV S2 (and presumably  FloppyDTV S2) because a
wrong opcode was sent.  The box only gave "not implemented" responses.
Changing the opcode to _TUNE_QPSK2 fixes this for good.

That code is in video_ioctl2, which gspca doesn't use.

Hi Adam,

This 'input_flags' should better go to the 'struct cam' (line 59).

topro 6800 driver

2009-03-27 Thread Andy Shevchenko
Hello.

Today I became to be (un)happy owner of 06a2:0003 device. I found nice
discussion here in this list, but I've just subscribed to it.
So, I have some free time to test and improve existent code. If I will
be helpful, tell me, please!
(I'm using Fedora 9, but I could compile any additional driver for
that 2.6.27.15 kernel)

If the subject is important to ARM people, the reply messages should be there
as well. Otherwise you shouldn't c/c it since the beginning ;)

Subscribers only list are not good for patches discussion, and aren't
recommended by Linux practices. 

The issues become evident on such discussions where more than one
subsystem is envolved. 

We've switched this year to linux-media@vger.kernel.org mainly due to that: the
anti-spam filters at VGER are so efficient that we don't need to be
subscribers-only anymore. I suggest that you try to argue with ARM list
maintainer to do the same. 

At the mean time, please c/c only lists that don't require subscriptions, since
people shouldn't be forced to subscribe just to reply an email, and it is not
polite to send emails refusing their comments.

Cheers,
Mauro

?

Or in v4l2_open function i can check if vdev->fops->open == NULL before
video_get(vdev); (increasing the device refcount), and if it's NULL then
unlock_mutex and return 0 ?
And the same in v4l2_release - just return 0 in the begining of function
in case vdev->fops->release == NULL ?

What approach is better ?

Probably because you didn't generate it against the development tree. Could you

The better is to clone it using:

It didn't apply against the development tree. Anyway, a recent patch removed
the need of memset there. the memory fill with zero now happens at the same
code we copy the structure values.

V4L2_CID_FOCUS_AUTO is meant to change the auto-focus mode. Can you describe 
FOCUS_MACRO and FOCUS_NORMAL in more details ? Are they auto-focus modes or 
just focus presets ?

Does an auto-macro focus mode really exists ?

[patch review] gspca - mr97310a: return error instead of -1 in sd_mod_init

2009-03-27 Thread Alexey Klimov
Hello, Jean-Francois

What do you think about such small cleanup ?

Patch reformats sd_mod_init in the way to make it return error code from
usb_register instead of -1.

No, they are not calling C from FIQs and they are not protecting against 
FIQs with a spinlock_irq*, that was my misinterpretation, sorry.

trouble with v4l-dvb compilation, compat.h: redefinition of 'usb_endpoint_type'

Then i updated v4l-dvb repository(hg pull, hg update) and configured

This drivers compile ok in kernel from kernel.org.

This is precisely the area where FIQs can't be used.  You can't take
spinlocks (even IRQ-safe spinlocks) from FIQs.  Why?  You'll deadlock.

Consider:

spin_lock_irqsave(lock, flags);
...
FIQ happens
FIQ:spin_lock_irqsave(lock, flags); <=== deadlock

And there's nothing you can do about that.  And no, converting this
locking primitive to also disable FIQs means that then FIQs will be
subject to the same latency as normal IRQs.

In fact, in uniprocessor mode, you might as well completely forget the
spinlock, because the lock part is a no-op, and the IRQ disable has no
effect on FIQs.

If you're going to be using FIQs in C code, you need to be _very_ _very_
careful about what you do.  Calling normal kernel functions is generally
not going to be safe in any way.

Re: [linux-dvb] Patch for DigitalNow TinyTwin remote.

2009-03-27 Thread Antti Palosaari

Hei Stuart,
I would like to thank you!


Someone should really examine that more. Take some sniffs to see how
Windows handle that.
http://www.linuxtv.org/pipermail/linux-dvb/2008-November/030292.html
http://linuxtv.org/wiki/index.php/MSI_DigiVox_mini_II_V3.0


I had a look at the links, the problem I had did not stop after pressing a key on the keyboard. Also, with this kernel (2.6.29_rc7) using 'options usbhid quirks=0x13d3:0x3226:0x0004' had no effect, I believe there have been some changes to usbhid in 2.6.28, either way 
the old macro '#define HID_QUIRK_IGNORE 0x0004' is not in hid.h in this kernel version. The only way to stop it was to unplug the device. (Trying to type rmmod was impossible as the input from the remote would keep coming!)


I'd be happy to have a look in to usb sniffing, are there any decent tutorials 
on how to do this?


take sniff:
http://www.pcausa.com/Utilities/UsbSnoop/default.htm
use parser to sniff:
v4l2-apps/util/parse-sniffusb2.pl

and try to look parsed log. You can see USB-protocol rather easily by 
comparing driver code and sniff.



I am also not sure about HID changes.
And also could you test whether AzureWave IR-tables are OK because
device looks just same, even remote.


You're absolutely right! The TinyTwin worked with the AzureWave tables 
(af9015_rc_keys_twinhan and af9015_ir_table_twinhan).

I can see in af9015.h there is an ir table (af9015_ir_table_twinhan) with 50 entries, a key table (af9015_rc_keys_twinhan) with 53 entries and that while the remote has 53 keys, the device can only handle 50 of them (the first 50 in the ir table if > 50). I've also 
found two ir tables from Windows drivers (one from the supplied CD and the one I previously mentioned for Windows MCE). This is an example entry in an ir table:


you are correct, 50 entries is max size.


 1  ,  2  ,  3  ,  4  ,  5  ,  6  ,  7
0x00, 0xff, 0x16, 0xe9, 0x28, 0x0c, 0x00

I'm assuming columns 3 & 4 correspond to the key pressed and columns 5 & 6 correspond to the code returned when that key is pressed. In all tables, 3 & 4 are the same while 5 & 6 are sometimes different. I'm assuming that 5 & 6 are important if usbhid attaches itself 
to the device, however, if dvb_usb_af9015 attaches itself then they seem somewhat arbitrary as the key table only needs to match the ir table to get the correct key press from af9015_rc_query.


bytes 1-4 are remote code, 1 & 2 is like device address and 3 & 4 
contains key code. Last 3 bytes are some data returned by chip, HID / 
key code.

http://www.sbprojects.com/knowledge/ir/rc6.htm
http://www.sbprojects.com/knowledge/ir/nec.htm

I wrote a simple programme to look at all the ir and key tables. Looking at af9015_rc_keys_twinhan and af9015_ir_table_twinhan in af9015.h shows there is no entry in af9015_ir_table_twinhan for A/V, Zoom+ or Zoom- and there are two entries with '0x00, 0x0e' 
corresponding to KEY_POWER and KEY_INFO (I believe the entry '{ 0x00, 0x0e, KEY_POWER }' should be '{ 0x00, 0x4d, KEY_STOP }') in af9015_rc_keys_twinhan.


I'm not sure if columns 5 & 6 need to be specific values, but I've attached a 
complete list (53 ir table entries and 53 corresponding key table entries). Of 
course, we can only use 50 of them at a time!

Also, how does the AzureWave handle the remote? Does it use the usbhid driver 
or dvb_usb_af9015? If it uses dvb_usb_af9015, then I think the TinyTwin should 
use it as well and it would be necessary to stop usbhid from attaching to the 
device.


When I added remote support the reason I used polling was that I didn't 
get HID working. I don't know why. And I haven't even sniffed how 
Windows driver handles that - only uploaded ir-table to the device as 
seen from sniffs.


Could you make patch that adds AzureWave remote to the TinyTwin? 2.6.30 
merge windows is now open. I will try to examine this remote issue 
during weekend. Use this tree http://linuxtv.org/hg/~anttip/af9015/

Doesn't look like a good idea to me. You don't restrict picture sizes in

You use an FIQ for SoF, and spin_lock_irqsave() to protect. Don't they 
only disable IRQs and not FIQs? But it seems your FIQ cannot cause any 
trouble, so, it should be fine. Do you really need an FIQ?


yes, FIQ is necessary. Because IRQ is to slow. When SoF is detected, DMA must 
be activated immediately, but not to early.
Whe tried to use IRQ, and many starts of frames were missed.
May I remove these spin_lock_irqsave's?

Hm, looks like an error in the datasheet:

1 = SOF

This is not a status bit, but a control "SoF interrupt enable" bit, right?


Yes, probably it's only 'small' error in datasheet :)

AFAIU, your flow looks as follows:

1. configure DMA, enable Start of Frame FIQ
2.  enable DMA, DMA IRQ, disable SoF FIQ
3.  disable DMA, report completed buffer, goto 1

I don't understand this. In your CSI_BUS_FLAGS you only support 8 bits. If

Of course ;-) The PCI ID of the card is not listed. I happen to have
the same card, you can add the ID to the list but note that the
frontend is not there yet... so the module will load, will print some
something... and that's it.
I have a couple of patches queued and I plan to do some
experimentation in the weekend though ;)

This issue should be resolved now, /tmp had insufficient space.

BTW: it is faster and uses less disk space to use hg-menu to

With that pipe draining code, the USB controller response is weird,
i2c doesn't work.
But Timothy Lee said he need that to drain the pipe after hibernate.
Seems some TS data remains in the pipe
that troubles mplayer.

I don't know if I should remove the that signal strength code.
LGS8913 codes already use a very slow loop get get signal strength.
It loops from 1 to 915 (for 915 guard intervals), set a register and then read.
Such loop is very slow, that's why I add a fake signal strength.

for LGS8GL5 and newer chips, it reads two register to roughly get the
AGC output value.

seems LGS8913 can use the new method too. Perhaps we can remove the
fake signal strength code.

That's the code copied from another frontend when I start the work.
But currently I would like to make it AUTO only.
Yes, I think there is a need for DMB-TH API.
FYI, DMB-TH is union of two modes, single carrier and multi-carrier.
The multi carrier mode is very DVB-T 8MHz alike.
The single carrier mode, I guess, is ATSC like.
I am not very familiar with RF and DTV technology and there is no
single carrier mode broadcast in Hong Kong.
It is very welcome to open a new thread to discuss proposal for DMB-TH API

Yes, I read your SNR discussion.
The register read is called average noise magnitude, but I don't know the unit.
There is no description from vendor.

Why people insist on sending patches to the legacy list? If you don't send the

The only way to send patches to patchwork is to submit it via linux-media list.
There's no other way. So, all patch discussions and reviews should happen at
the ML, by replying at the patch email (or by replying another reply).
Patchwork will keep track of such replies as well.

If you have a motor and you are able to automatically peak satellites,
the only thing missing is a program to find all the signals automatically,
including the ones which are turned on and off in a matter of minutes.

Just google for *blindscan* (and maybe my name) to find a
utility I wrote years ago and abandoned after failing to get
the corresponding mt312-autosymbolrate kernel patch integrated.

Next step, automatically upload found signals on some site, maybe
including a frame from the received video stream and let users
comment/moderate interesting ones on a sort of forum. :-)
H, feeds...

If the mutex.h were already included by another kernel header, I don't see why
to include it again. If a later patch remove the mutex.h from the header, then
the patch author should take care of this change anyway.

Could you please provide a clearer description? Why is it problematic? Also,

Since the patch will appear after 2.6.29, you should test using 2.6.29.

Patch is ok. However, as it depends on the previous one, I'll mark it as RFC. 
When you submit back the previous patch (plus the API patch), re-submit the 
other patches on this series.

Also, since those patches are dependent, please number they at the subject, as:

[PATCH 01/05] 
...
[PATCH 05/05] 

This allows us to be sure about the proper patch order to apply.

Hmm... this is weird.

That's said, maybe you may need some DVBS2 API additions for DMB. You should

Same here: if there's no exact match, we should first patch the core files to
improve the API, and then use the correct values.

The above seems weird. It would be better to do:

+   fe_params->u.ofdm.code_rate_LP = translated_fec;

The gcc optimizer will produce the same code, but this way would be cleaner for

I dunno if you are following all those discussions about SNR. We're trying to
standardize the meaning for all those status reads (SNR, signal strength, etc.

Nothing were decided yet, but while we don't take a decision, the better is if
you provide some comments at the source code specifying what's the unit for

You're right in that gstreamer expects:

outsize = GST_ROUND_UP_4 (*w) * GST_ROUND_UP_2 (*h);
outsize += 2 * ((GST_ROUND_UP_8 (*w) / 2) * (GST_ROUND_UP_2 (*h) / 2));

I tried to hack around this by changing the 8 to a 4 which produces
the same image as when I added the 584 offset.
My take is that the alignment is also used somewhere else in the
gstreamer stack. I'll try to post on their devel list and see if I can
get any tips on how to resolve this problem.

Best regards,
Erik

[PATCH]: gspca: use usb interface as parent

2009-03-27 Thread Hans de Goede

Hi all,

As discussed in the:
"v4l parent for usb device interface or device?"
thread, here is a patch for gspca to make it use
the usb interface as its parent device, instead
of the usb device.

Regards,

Hans

p.s.

I'll also push a patch to my libv4l repo, with
matching libv4l changes so that libv4l's upside
down cam detections stays working with this change.

Note: this libv4l patch also fixes libv4l upside
down detection for the new device numbering style.

I think it could be more than that. Because some ISP devices support
much more presets like "AF-S" and "AF-C".
I mean AF Static? or something for AF-S and AF continuous for AF-C...

You are right. But on the other hand, it seems to be not bad using API
in same way as EXPOSURE CID (V4L2_CID_EXPOSURE_AUTO) to avoid
confusion.

Line 31 is the KBUILD_CFLAGS line of:

ifeq ($(CONFIG_FRAME_POINTER),y)
KBUILD_CFLAGS   +=-fno-omit-frame-pointer -mapcs -mno-sched-prolog
endif

which is _not_ a recursive definition.  Either your make is broken or
you have local changes to that line.

Timothy Lee.

To get rid of some of the warnings, you can analyze only the 
parts of the source that you're working on. You just need sparse 
in your PATH and issue:

$ make SUBDIRS=arch/arm/mach-mx2 C=2


Unfortunately, the arm tree is a bit different to mainline linux, 
because

$ make SUBDIRS=arch/arm C=2
arch/arm/Makefile:31: *** Recursive variable `KBUILD_CFLAGS' 
references itself (eventually).  Stop.
make: *** [_module_arch/arm] Error 2

breaks, with and without sparse:

So, you _do_ know what that parameter does - if you can verify what effect 
it produces on the camera? So, that's just what I was asking - what do 
these settings do? What changes do you observe when you manipulate them? 
And this your observation actually suffices to me to preserve your 
original order of register writes. If documentation says nothing about it, 
and as long as it works - we can keep it.

Well, I don't think we have to wait for an answer for too long. If they 
don't reply within 1-2 days, let's just take the patch as is (with the 
single minor correction I proposed).

That's up to you. This is a minor formatting correction, which I can do 
myself when merging. But if you like, you can send an update, sure.

Seems way to complicated to me. Remember that end users have no idea about 
the device addresses, so it should be a simple to understand module option. 
So I'd just go with Steve's preference.

This seems more logical to me:

enum v4l2_focus_mode {
V4L2_FOCUS_MANUAL = 0,
V4L2_FOCUS_AUTO_NORMAL = 1,
V4L2_FOCUS_AUTO_MACRO = 2,
};

At least this maps the current boolean values correctly. I'm not sure from 
your decription what the fourth auto focus mode is supposed to be.

But I think it might be better to have a separate control that allows you to 
set the auto-focus mode. I can imagine that different devices might have 
different auto-focus modes.

I've CC-ed Laurent since this is more his field than mine.
