Re: gspca V4L2_CID_EXPOSURE_AUTO and VIDIOC_G/S/TRY_EXT_CTRLS
On Wed, 18 Apr 2012 15:37:20 +0200 Antonio Ospite osp...@studenti.unina.it wrote: I noticed that AEC (Automatic Exposure Control, or V4L2_CID_EXPOSURE_AUTO) does not work in the ov534 gspca driver, either from guvcview or qv4l2. [snip] So in ov534, but I think in m5602 too, V4L2_CID_EXPOSURE_AUTO does not work from guvcview, qv4l2, or v4l2-ctrl, for instance the latter fails with the message: error 25 getting ext_ctrl Auto Exposure I tried adding an hackish implementation of vidioc_g_ext_ctrls and vidioc_s_ext_ctrls to gspca, and with these V4L2_CID_EXPOSURE_AUTO seems to work, but I need to learn more about this kind of controls before I can propose a decent implementation for mainline inclusion myself, so if anyone wants to anticipate me I'd be glad to test :) Unrelated, but maybe worth mentioning is that V4L2_CID_EXPOSURE_AUTO is of type MENU, while some drivers are treating it as a boolean, I think I can fix this one if needed. Hi Antonio, Yes, V4L2_CID_EXPOSURE_AUTO is of class V4L2_CTRL_CLASS_CAMERA, and, as the associated menu shows, it is not suitable for webcams. In the webcam world, the autoexposure is often the same as the autogain: in the knee algorithm (http://81.209.78.62:8080/docs/LowLightOptimization.html - also look at gspca/sonixb.c), both exposure and gain are concerned. The cases where a user wants only autoexposure (fixed gain) or autogain (fixed exposure) are rare. If you want people to be able to do that, you should add a new webcam control, V4L2_CID_AUTOEXPOSURE, and also add it to each driver which implements the knee algorithm, and handle the three cases, autogain only, autoexposure only and knee. Then, looking about your implementation of vidioc_s_ext_ctrls, I found it was a bit simple: setting many controls is atomic, i.e., if any error occurs at some point, the previous controls should be reset to their original values. Same about vidioc_g_ext_ctrls: the mutex must be taken only once for the values do not change. You also do not check if the controls are in a same control class. Anyway, are these ioctl's needed?

Re: [RFC PATCH 3/3] [media] gspca - main: implement vidioc_g_ext_ctrls and vidioc_s_ext_ctrls
Hi Antonio,
My apologies for the late review, I missed this the first time around.
Since I am the 'control guy' :-) I thought I should give my view on this.
And that is the real long-term approach to implementing extended controls
in gspca is to add support in gspca for the control framework (see
Documentation/video4linux/v4l2-controls.txt). That will probably simplify
control handling in gspca anyway. The main problem is how to do it in such
a manner that we can convert gspca drivers to the control framework one by
one.
I am inclined to NACK code that adds a driver-specific extended control
implementation instead of going to the control framework because I know
from painful personal experience that it is very hard to get it right.
I might have some time (no guarantees yet) to help with this. It would
certainly be interesting to add support for the control framework in the
gspca core. Hmm, perhaps that's a job for the weekend...
Regards,
Hans

This makes it possible for applications to handle controls with a class
different than V4L2_CTRL_CLASS_USER for gspca subdevices, like for
instance V4L2_CID_EXPOSURE_AUTO which some subdrivers use and which
can't be controlled right now.
See
http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/47010
for an example of a problem fixed by this change.
NOTE: gspca currently won't handle control types like
V4L2_CTRL_TYPE_INTEGER64 or V4L2_CTRL_TYPE_STRING, so just the
__s32 field 'value' of 'struct v4l2_ext_control' is handled for now.

[RFC 1/1] v4l: Implement compat handlers for ioctls containing enums
Quite a few V4L2 IOCTLs contained enum types in IOCTL definitions which are
considered bad. To get rid of these types, the enum types are replaced with
integer types with fixed size. This causes the actual IOCTL commands to
change, which requires special handling during the transition period to new
IOCTL commands.

Hi all,
I'm sending this as RFC and this what it really means: I haven't tested the
patch, not even compiled it. What I'd like to ask is how do you like the
approach. Handling for only one IOCTL is implemented.
The compat IOCTLs are recognised and special handling for them is performed
in place of copy_from_user() and copy_to_user(). I do not handle array
IOCTLs yet.
I thought of the option of copying everything to kernel space first and then
performing the conversion there, but doing it at the same time does not seem
to cause much additional complications. The expense is likely more CPU time
usage but less stack usage / memory allocation which also can consume
noteworthy amounts of CPU time.
This patch goes on top of Mauro's earlier patch.

- * Samsung S5P/EXYNOS4 SoC series camera interface
[PATCH 00/13] V4L: Exynos 4x12 camera host interface (FIMC-LITE) driver
This change set adds support for FIMC-LITE devices, available in Exynos4x12 (and Exynos5) SoCs, to the existing s5p-fimc driver. I have tested only DMA output operation (through a corresponding video node). The FIMC-LITE differs from regular FIMC in that it doesn't have a scaler, rotator and color converter and a DMA input. So it's just basic camera host interface, with additional internal FIFO data output to other SoC sub-modules. Cropping at the host interface input is exposed on a subdev sink pad through the selection API, and composition performed by the output DMA engine can be controlled through selection compose targets on the video node. I tried to make the exynos-fimc-lite module as much independent as possible, to allow its reuse on any other SoCs that have same IP block. This change set also includes small enhancement of V4L2_CID_COLORFX and a patch adding support for this control at the s5p-fimc driver.

[PATCH 01/13] V4L: Extend V4L2_CID_COLORFX with more image effects
This patch adds definition of additional color effects: - V4L2_COLORFX_AQUA, - V4L2_COLORFX_ART_FREEZE, - V4L2_COLORFX_SILHOUETTE, - V4L2_COLORFX_SOLARIZATION, - V4L2_COLORFX_ANTIQUE, - V4L2_COLORFX_ARBITRARY_CBCR. The control's type in the documentation is changed from 'enum' to 'menu' - V4L2_CID_COLORFX has always been a menu, not an integer type control. The V4L2_COLORFX_ARBITRARY_CBCR option enables custom color effects, which are impossible or impractical to define as menu items. The V4L2_CID_BLUE_BALANCE and V4L2_CID_RED_BALANCE controls allow in this case to configure the Cb, Cr coefficients.

[PATCH 03/13] s5p-fimc: Simplify the variant data structure
Remove num_entities from the driver data structure as this information
is already there as the variant array's length. Remove the 'samsung_'
prefix from some data structures since it doesn't really carry any
useful information and makes the names unnecessarily long.

[PATCH 04/13] s5p-fimc: Use v4l2_subdev internal ops to register video nodes
In order to be able to select only FIMC-LITE support, which is added
with subsequent patches, the regular FIMC support is now contained
only in fimc-core.c, fimc-m2m.c and fimc-capture.c files. The graph
and pipeline management is now solely handled in fimc-mdevice.[ch].
This means the FIMC driver can now be excluded with Kconfig option,
leaving only FIMC-LITE and allowing this driver to be reused in SoCs
that have only FIMC-LITE and no regular FIMC IP.

[PATCH 09/13] s5p-fimc: Make sure the interrupt is properly requested
Use dev_name() for requesting an interrupt so we don't get an interrupt
requested with same name for multiple device instances.
While at it, tidy up the driver data handling.

[PATCH 07/13] s5p-fimc: Rework the video pipeline control functions
There is getting more entities to manage within single video pipeline
in newer SoCs. To simplify code put subdevs' pointer into an array
rather than adding new member in struct fimc_pipeline for each subdev.
This allows to easier handle subdev operations in proper order.
Additionally walk graph in one direction only in fimc_pipeline_prepare()
function to make sure we properly gather only media entities that below
to single data pipeline. This avoids wrong initialization in case where,
for example there are multiple active links from s5p-mipi-csis subdev
output pad.
struct fimc_pipeline declaration is moved to the driver's public header
to allow other drivers to reuse the fimc-lite driver added in subsequent
patches.

[PATCH 11/13] s5p-fimc: Add support for Exynos4x12 FIMC-LITE
This patch adds driver for FIMC-LITE camera host interface. This new IP differs from the regular FIMC IP in that it doesn't have input DMA, scaler and color space conversion support. So it just plain camera host interface for MIPI-CSI2 and ITU-R interfaces. For the serial bus support it interworks with MIPI-CSIS and the exisiting s5p-csis driver. The FIMC-LITE and MIPI-CSIS drivers can also be reused in the Exynos5 SoC series.

Re: [PATCH 01/13] V4L: Extend V4L2_CID_COLORFX with more image effects
Hi Sylwester! On Friday, April 27, 2012 11:52:54 Sylwester Nawrocki wrote: This patch adds definition of additional color effects: - V4L2_COLORFX_AQUA, - V4L2_COLORFX_ART_FREEZE, - V4L2_COLORFX_SILHOUETTE, - V4L2_COLORFX_SOLARIZATION, - V4L2_COLORFX_ANTIQUE, - V4L2_COLORFX_ARBITRARY_CBCR. The control's type in the documentation is changed from 'enum' to 'menu' - V4L2_CID_COLORFX has always been a menu, not an integer type control. The V4L2_COLORFX_ARBITRARY_CBCR option enables custom color effects, which are impossible or impractical to define as menu items. The V4L2_CID_BLUE_BALANCE and V4L2_CID_RED_BALANCE controls allow in this case to configure the Cb, Cr coefficients. So this just hijacks the RED/BLUE_BALANCE controls for a different purpose? If I understand this 'effect' correctly it just replaces the Cb and Cr coefficients with fixed values, basically giving you a BW picture (the Y coefficient), except that it is really a 'BlackFixedColor' picture. I think you should add a new control for setting this. V4L2_CID_COLORFX_COLOR or something.

It would certainly be interesting to add support for the control framework in the gspca core. Hmm, perhaps that's a job for the weekend... Hi Hans, I hope you will not do it! The way gspca treats the controls is static, quick and very small. The controls in the subdrivers ask only for the declaration of the controls and functions to send the values to the webcams. Actually, not all subdrivers have been converted to the new gspca control handling, but, when done, it will save more memory. Actually I've moving gspca over to the control framework on my to-do list. This will allows us to remove hacks like we have in sonixb.c for coarse exposure / fine exposure controls. More in general it will allow (in an easy way) to have per sensor control min/max/step values. But the most important reason for me to want to use the control framework in gspca is to get support for control events. Which allow a control-panel app to dynamically update its display when settings are changed to some other way (ie another control app, or software autogain). I do plan to do this in way so that we can do this one subdriver at a time. I've no idea when I'll get around to doing the first driver though :) Regards, Hans -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Hi Antonio, Yes, V4L2_CID_EXPOSURE_AUTO is of class V4L2_CTRL_CLASS_CAMERA, and, as the associated menu shows, it is not suitable for webcams. Where is that menu you refer to? Maybe camera_exposure_auto in drivers/media/video/v4l2-ctrls.c which mentions also Shutter Priority Mode and Aperture Priority Mode? Naively one would expect that a web _camera_ could use some controls of type V4L2_CTRL_CLASS_CAMERA. In the webcam world, the autoexposure is often the same as the autogain: in the knee algorithm (http://81.209.78.62:8080/docs/LowLightOptimization.html - also look at gspca/sonixb.c), both exposure and gain are concerned. From the document you point at I still understand that from a user point of view autoexposure and autogain are _independent_ parameters (Table 1), it's just that for such algorithm to work well they should be _both_ enabled. The cases where a user wants only autoexposure (fixed gain) or autogain (fixed exposure) are rare. If you want people to be able to do that, you should add a new webcam control, V4L2_CID_AUTOEXPOSURE, and also add it to each driver which implements the knee algorithm, and handle the three cases, autogain only, autoexposure only and knee. The real problem here is that _manual_ exposure does not work in ov534 because the user cannot turn off what we are currently calling auto exposure. Then, looking about your implementation of vidioc_s_ext_ctrls, I found it was a bit simple: setting many controls is atomic, i.e., if any error occurs at some point, the previous controls should be reset to their original values. Same about vidioc_g_ext_ctrls: the mutex must be taken only once for the values do not change. You also do not check if the controls are in a same control class. I see, it was my first shot and I just wanted to start the discussion with a works here implementation.

Hi Antonio, Yes, V4L2_CID_EXPOSURE_AUTO is of class V4L2_CTRL_CLASS_CAMERA, and, as the associated menu shows, it is not suitable for webcams. Where is that menu you refer to? Maybe camera_exposure_auto in drivers/media/video/v4l2-ctrls.c which mentions also Shutter Priority Mode and Aperture Priority Mode? Naively one would expect that a web _camera_ could use some controls of type V4L2_CTRL_CLASS_CAMERA. In the webcam world, the autoexposure is often the same as the autogain: in the knee algorithm (http://81.209.78.62:8080/docs/LowLightOptimization.html - also look at gspca/sonixb.c), both exposure and gain are concerned. From the document you point at I still understand that from a user point of view autoexposure and autogain are _independent_ parameters (Table 1), it's just that for such algorithm to work well they should be _both_ enabled. The cases where a user wants only autoexposure (fixed gain) or autogain (fixed exposure) are rare. If you want people to be able to do that, you should add a new webcam control, V4L2_CID_AUTOEXPOSURE, and also add it to each driver which implements the knee algorithm, and handle the three cases, autogain only, autoexposure only and knee. The real problem here is that _manual_ exposure does not work in ov534 because the user cannot turn off what we are currently calling auto exposure. Then, looking about your implementation of vidioc_s_ext_ctrls, I found it was a bit simple: setting many controls is atomic, i.e., if any error occurs at some point, the previous controls should be reset to their original values. Same about vidioc_g_ext_ctrls: the mutex must be taken only once for the values do not change. You also do not check if the controls are in a same control class. I see, it was my first shot and I just wanted to start the discussion with a works here implementation. I think that using some v4l2 infrastructure like the control-framework like Hans proposes could be better in the long run. IIUC this could also prevent drivers having to handle menu entries themselves like we are doing now in sd_querymenu(), right? Correct. If you two reach an agreement and he gets to do it I'll surely port over drivers using V4L2_CID_EXPOSURE_AUTO. Anyway, are these ioctl's needed? Whether they are really needed or not, that depends on the definition of webcam, the definition of camera in V4L2, and the relationship between the two. If a webcam IS-A v4l2 camera, then I'd expect it to be able to use V4L2_CTRL_CLASS_CAMERA controls, and then EXT controls should be made accessible by gspca somehow. The UVC driver definitely uses the camera class controls. So they are really meant for webcam use :-) Note that for technical reasons the UVC driver is the only driver that will not use the control framework (partially due to design of the datastructures and partially due to the complex control handling/mapping and the support of dynamic controls in UVC). Perhaps in the future we might try to get it into UVC anyway, but not before all other drivers have been converted.

If you change register 0x80 in bank/page 1 to 42 on pac7311 or larger then circa 100 on pac7302, you will get markers with bit 8 set. When this happens you will initially get markers 0xa0 - 0xa4 ... 0xbc and the stream tends to stabilize on 0xbc. Likewise if you remove the artificial limiting of the pac7302 to 15 fps from the driver you will get markers 0x44 - 0x48 ... 0x7c. The images look a lot better with bit 8 set, so I plan to run some tests wrt what framerates can safely handle that (it uses more bandwidth) and set bit 8 on lower framerates. I carefully looked at the ms-windows pac7302 traces I have. The register 1-80 stays always in the range 0d..11, except sometimes 19 at start time. Right, that can mean one of 2 things: 1) The traces were made during daylight, so low exposure / high framerate, and enabling the lower compression modes (which cause bit 7 of the marker to get set) is a bad idea at high framerates 2) The windows driver never enables the low compression mode. I seriously doubt that this is the case, ie older versions of the pac7311 driver have (commented) writes to page 1 register 80 with high enough values to enable it and I'm pretty sure those writes come from windows traces. In these traces, the images with marker 44 (dec 68) look really better with all 08's as the quantization table. After having played with the quantization tables you've found I agree. [snip] Yeah short of someone disassembling and reverse-engineering the windows driver we will probably never figure out the exact correct tables. Well, I got the SPC230NC.SYS of the ms-windows pac7302 driver, but it is not easy to disassemble because it has no symbol table.

Yes they do, good find! I've done yet more testing / trial and error with these tables and I've just pushed another Pixart JPEG patch to v4l-utils git switching to these new tables. Thanks! Also with these tables the quality difference between high/low compression mode becomes significantly less. So much less that I've decided to not further pursue enabling low compression mode in the gspca drivers, esp. since this will cause pain for people with an older libv4l. BTW, I don't think the exposure and gain controls use the right registers as they are coded in the actual gspca pac7302 subdriver. The ms-windows driver uses the registers (3-80 / 3-03), (3-05 / 3-04), (3-12) and (1-80) for autogain/exposure. The gspca test tarball of my web site includes a new AGC using these registers, but it does not work well. Maybe you could tell me what is wrong with it... Let me get back on that in a separate mail.

[PATCH/RFC v3 00/14] V4L camera control enhancements
Here is one more update of the camera class controls change set. The changes since v2 are: - V4L2_CID_WHITE_BALANCE_PRESET replaced with V4L2_CID_AUTO_N_PRESET_WHITE_BALANCE according to suggestions from Hans de Goede; - added Flurescent H white balance preset; - V4L2_CID_IMAGE_STABILIZATION and V4L2_CID_WIDE_DYNAMIC_RANGE controls type changed from boolean to menu, to make any further extensions of these controls easier; I'm just not 100% sure if V4L2_WIDE_DYNAMIC_RANGE_ENABLED and V4L2_IMAGE_STABILIZATION_ENABLED are good names for cases where the camera doesn't support wide dynamic range or image stabilization technique selection and only allows to enable or disable those algorithms; - V4L2_CID_ISO_SENSITIVITY_AUTO control type changed from boolean to menu in order to support ISO presets; currently enum v4l2_iso_sensitivity_auto_type does not contain any presets though; - V4L2_CID_COLORFX patch removed from this series; - updated vivi and s5c73m3 driver patches. Changes since v1 (implicit): - the V4L2_CID_AUTO_FOCUS_FACE_PRIORITY control merged with V4L2_CID_AUTO_FOCUS_FACE_AREA, - many minor documentation corrections, - removed 08/23 V4L: camera control class... patch, which got accidentally added at v1, - added V4L2_CID_SCENE_MODE and V4L2_CID_3A_LOCK controls, - added vivi patch for testing.

[PATCH/RFC v3 09/14] V4L: Add camera 3A lock control
The V4L2_CID_3A_LOCK bitmask control allows applications to pause
or resume the automatic exposure, focus and wite balance adjustments.
It can be used, for example, to lock the 3A adjustments right before
a still image is captured, for pre-focus, etc.
The applications can control each of the algorithms independently,
through a corresponding control bit, if driver allows that.

[PATCH/RFC v3 10/14] V4L: Add auto focus targets to the selections API
The camera automatic focus algorithms may require setting up
a spot or rectangle coordinates or multiple such parameters.
The automatic focus selection targets are introduced in order
to allow applications to query and set such coordinates. Those
selections are intended to be used together with the automatic
focus controls available in the camera control class.

Add V4L2_CID_WIDE_DYNAMIC_RANGE camera class control for camera wide
dynamic range (WDR, HDR) feature. This control has now only menu entries
for enabling and disabling WDR. It can be extended when the wide dynamic
range technique selection is needed.

[PATCH/RFC v3 01/14] V4L: Add helper function for standard integer menu controls
This patch adds v4l2_ctrl_new_std_int_menu() helper function which can
be used in drivers for creating standard integer menu control. It is
similar to v4l2_ctrl_new_std_menu(), except it doesn't have a mask
parameter and an additional qmenu parameter allows passing an array
of signed 64-bit integers constituting the menu items.

The camera may in some conditions incorrectly determine the exposure,
and a manual automatic exposure correction may be needed. This patch
adds V4L2_CID_AUTO_EXPOSURE_BIAS control which allows to add some
offset in the automatic exposure control loop, to compensate for
frame under- or over-exposure.

How do I detect if disconnect is called due to module removal?
Hi all, I'm cleaning up some USB FM radio drivers and I realized that I need to know in the disconnect callback whether I'm called due to a module unload or due to an unplug event. In the first case I need to first mute the audio output of the device, in the second case I can skip that. I can just try and always mute the device but that results in a error message in the case the device is unplugged. Is there a field I can test somewhere to detect what caused the disconnect?

Hi Hans, thanks for the review! On 04/27/2012 12:12 PM, Hans Verkuil wrote: Hi Sylwester! On Friday, April 27, 2012 11:52:54 Sylwester Nawrocki wrote: This patch adds definition of additional color effects: - V4L2_COLORFX_AQUA, - V4L2_COLORFX_ART_FREEZE, - V4L2_COLORFX_SILHOUETTE, - V4L2_COLORFX_SOLARIZATION, - V4L2_COLORFX_ANTIQUE, - V4L2_COLORFX_ARBITRARY_CBCR. The control's type in the documentation is changed from 'enum' to 'menu' - V4L2_CID_COLORFX has always been a menu, not an integer type control. The V4L2_COLORFX_ARBITRARY_CBCR option enables custom color effects, which are impossible or impractical to define as menu items. The V4L2_CID_BLUE_BALANCE and V4L2_CID_RED_BALANCE controls allow in this case to configure the Cb, Cr coefficients. So this just hijacks the RED/BLUE_BALANCE controls for a different purpose? Uh, the meaning is indeed a bit different. Probably not a good idea to reuse the controls like this in the standard API. If I understand this 'effect' correctly it just replaces the Cb and Cr coefficients with fixed values, basically giving you a BW picture (the Y coefficient), except that it is really a 'BlackFixedColor' picture. Yes, this is also my understanding. The TRMs are not very verbose about it, but I think it is exactly how it works. The effect is similar to looking through a coloured glass, where colour changes from green through red to violet when changing the (CR, CB) coefficients gradually from (0, 0) - (0, 255) - (255, 255). I think you should add a new control for setting this. V4L2_CID_COLORFX_COLOR or something. Do you mean something similar to V4L2_CID_BG_COLOR ? When a different colour space is used then the range for those Cb, Cr components changes. It can be 0...255 or 16...240. So best would be to have 2 controls, for reporting min/max to the user. Maybe it would be better to add a V4L2_COLORFX_COLOR menu entry and V4L2_CID_COLORFX_CB, V4L2_CID_COLORFX_CR controls ? -- Regards, Sylwester -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Mauro, well said and thanks for standing up and defending the open-source. so, m88ds3103 in it's current version is just combination of using shuffling of my ds3000 code plus using copyrighted code by Montage Technologies - the last is even another reason why m88ds3103 can't be accepted, because then actually Montage Technologies should be listed in the copyright and wait for their approval. let me give example what i mean - let's take ToneBurst function as example - m88ds3103_diseqc_send_burst() - at the current version of m88ds3103 it's exactly the same code as the one from the reference code copyrighted by Montage Technologies and provided by them under NDA (i have access to that code), in the previous versions of m88ds3103 it was the same function as mine in ds3000_diseqc_send_burs() in ds3000.c - in both cases m88ds3103 can't be accepted. also, if you look at mine ToneBurst function ds3000_diseqc_send_burs() in ds3000.c you will see it's quite different than the one copyrighted by Montage Technologies, e.g. some of the register settings are different, etc, because i made it really from scratch - it could be even it's not better than the original settings used by the code copyrighted by Montage Technologies, but it's at least something genuine to which i came up - of course, the chip limits you in the ways how you can control it. last, but not least, just changing the condition of if-else statements (swapping it) and using do-while-loop instead for-loop is nothing more then shuffling the code. so, what i would accept: - patch against ds3000.c that adds ds3103 support: copyright is unchanged and instead credit for the ds3103 support is get by history note, example what i mean and how is the right way to be done in my opinion: === Montage Technology DS3000/TS2020 - DVBS/S2 Demodulator/Tuner driver Copyright (C) 2009 Konstantin Dimitrov kosio.dimit...@gmail.com Copyright (C) 2009 TurboSight.com History: April 2012: Add support for the new silicone revision ds3103 Max nibblenibble@gmail.com === - any changes that don't involved ds3103 support are subject to review and argumentation why they are done, i.e. they are bug, the setting is wrong, etc. Using the seperate tuner and demod, I need to change the codes which use the ds3000 frontend. How can I test the code to confirm that these codes are right without these hardwards? Well, at the split patch, you shouldn't do anything but to split tuner and demod. This will make easier for others to test, if you don't have the hardware for testing. i haven't had time to read the emails and i'm still not sure what is the motivation to split them, because Montage tuner and demodulator are like married couple. however, if there is really motivation about that then let's do it - i will help as far as my spare time allows and even with the testing, i.e. that nothing got broken as result of that.

I don't know what is situation of these Montage chips and what are possible combinations. *But* there is many existing cases from the DVB-T I am aware. Things are done wrongly and all is implemented as a one big blob. After that new device is arrived and we cannot support it since existing drivers are not split. And it is not single case... i understand your point, but i believe with DVB-T is quite different than with DVB-S2, i.e. it's very rare to mix DVB-S2 tuners and demodulators in such way how it's done with DVB-T. in fact, i'm not aware of any such mixes in real-life. also, below i will give a lot of technical details, i.e. facts about CX24116 or TDA10071 and CX24118A and then i'm sure you will understand my point why the same discussion can be made for CX24116 and TDA10071 drivers. It may happen or it may not happen. You never known. But still it is nice to split drivers correctly to avoid such problems that could be possible in some day. And I don't even know how much those tuners and demods differs - I only saw that patch and it looked there was some differences, even so much that two tuner drivers could be good choice. are there such designs in real-life, e.g. either Montage demodulator with 3rd party tuner or actually more importantly for what you're suggesting Montage tuner (ts2020 or ts2022) with third party demodulator? it's more or less the same case as with cx24116 (and tda10071) demodulator, where the tuner (cx24118a) is controlled by the firmware and thus it's solely part of the demodulator driver, even that it's possible to control the cx24118a tuner that is used with cx24116 (and tda10071) designs directly bypassing the firmware. so, why we don't change in that way the cx24116 (and tda10071) drivers too? CX24116 and TDA10071 (I made TDA10071) are somehow different as tuner is driven by demodulator firmware. There is no tuner that needs to be driven by driver at least for now. it's off-topic, but anyway i think it would be useful information to you and most of it is in the public domains anyway and thus i won't break any rules. so, you can google for: * s2TDQR-C005F and get the datasheet of LG NIM that consists of CX24118A + CX24116, read page 14 of it, there is figure diagram about it : in short it gives you all the details how CX24118A is connected to the CX24116 and explains that when there is no support for the tuner in CX24116 firmware then tuner pass-through can be used and that CX24118A also can be used with tuner pass-through, i.e. direct control no matter that it's supported tuner in the CX24116 firmware * now google for BS2F7HZ0165 datasheet in PDF (not the product brief, the datasheet is scanned and ugly looking), which is SHARP NIM that consists of CX24118A + CX24116 and on page 6 you can get even more information and even how to program the tuner pass-through mode * further more you can google for MDVBS2-24116, which is NIM made by Comtech with CX24118A + CX24116 and get all CX24118A control registers and their meaning so, the above 3 PDFs that are in the public domain gives you
Re: [PATCH 1/6] m88ds3103, montage dvb-s/s2 demodulator driver
Mauro, your reasoning makes sense to me. so, let's split them and at least settle this part of the discussion - i will do as far as my spare time allows, as well make sure there are no some problems introduced after the split. also, in one email i've just sent in answer to Antti there is enough argument why such split, i.e. tuner-pass-through-mode is subject to discussion about CX24116 and TDA10071 drivers too. currently, majority of DVB-S2 demodulator drivers in the kernel are married to particular tuners and there is no split.

This has nothing to do with Montage devices, but with the way we write those drivers in Kernel. There are _several_ examples where the driver for a single silicon were turned into more than one driver. The biggest examples are the SoC chips, that are transformed into a large series of drivers. Another example is the cx88 driver: due to technical reasons, it was splitted into 4 drivers, one for each different PCI ID exported by it. The cx2341x driver is also an interesting example: while it used to be for a separate chip, the cx2341x functions are now part of IP blocks on newer Conexant chipsets. Those single chips require two drivers to work (cx2341x and the associated media PCI bridge driver). Looking into tuners, there are the tda18271 family of devices, with are supported by several drivers: tda827x, tda8290 and tda18271-fe, depending on how the actual device is mounted. Eventually, the actual tuner may also have a tda9887 inside it. So, there's nothing wrong on splitting it on separate drivers. In a matter of fact, we strongly prefer to have tuners separate from demods. Having them together can only be justified technically, if there are really strong reasons why they should be at the same driver. I probably missed this at my review for ds3000 (that's why it ended by being merged), but, on the review I did on it (accidentally due to m88ds3103 patchset review), it is clear that the tuner has actually a different I2C address (0x60) than the demod, and it is indeed a separate device. Sorry for slipping into it. Anyway, now that this is noticed, tuner and demod drivers should be split, especially since there are some patches floating around to add support for ds3103. As I said before, the right thing to do is: 1) split ds3000 from ts2020 at the existing driver; 2) add support for the newer chips (ds3103/ts2022) to the ds3000 and ds3103 drivers. 3) test if the patches adding support for the newer chips didn't break the support for existing hardware. My proposal is that tasks (1) and (3) should be handled by you. As Max wants to add support for some devices based on ds3103/ts2022, IMO, he can do the patches for (2) in a way that they would be acceptable by you, as the driver maintainer for ds3000/ts2020, testing with their devices.

Re: [PATCH 1/6] m88ds3103, montage dvb-s/s2 demodulator driver
hi Mauro, in the mean time i was actually pointed out that there is 3rd party tuner that is proved to work in practice with both Montage ds3k demodulator family, as well ST STV090x demods, i.e. there are such reference designs. so, the split further makes sense and in fact that should be make in way that both drivers for STV090x and Montage ds3k demodulator family can share tuners with each other. so, that's just note for the upcoming review of the patches i will submit - in short the split of Montage tuner and demodulator code i will make it in the same fashion as how the driver code for ST 6100/6110 tuner are split from STV090x driver, because that now, as i've just mentioned, makes sense from practical point of view since of the 3rd party tuner for which there is reference designs with both STV090x and Montage demodulator. also, that way STB0899, STV090x and Montage demodulator drivers can be used together with any other of the DVB-S2 tuners available in the kernel - ST 6100 and 6110 and soon TS2020. however, i want to pointed out few other problems - they are off-topic as not related to drivers for Montage chips, but related as far as we're putting some order and making things in a proper way and those those things are out of that order: - there are 2 drivers for the same DVB-S2 tuner: ST 6110, respectively stv6110.c and stv6110x.c - there are 2 drivers for the same DVB-S2 demodulator family: respectively stv090x* and stv0900* the above couldn't be more wrong - in fact i can submit patches to make all drivers that relies on stv090x* and stv6110.c to use stv090x* and stv6110x.c instead except the NetUP board, for which in my opinion someone should submit patches using stv090x* and stv6110x.c and subsequently stv090x* and stv6110.c be removed - unless someone have some real argument why stv090x* and stv6110.c should stay or even if for why they should replace stv090x* and stv6110x.c and subsequently stv090x* and stv6110x.c be removed instead. so, the case with ST 6110 and STV090x support is the most frustrating and out of order thing that i can indicate regarding the support of DVB-S2 chips in the kernel and i hope you will take care as maintainer to be resolved or at least someone to explain why the current state is like that - or point me out to explanation if such was already made to the mailing list. so, what i'm suggesting is spring cleaning of all DVB-S2 tuner/demodulator drivers in the kernel - if it's not done now in the future the mess will only increase. thank you, konstantin On Fri, Apr 27, 2012 at 10:36 PM, Mauro Carvalho Chehab mche...@redhat.com wrote: Hi Konstantin, Em 27-04-2012 16:01, Konstantin Dimitrov escreveu: Mauro, your reasoning makes sense to me. so, let's split them and at least settle this part of the discussion - i will do as far as my spare time allows, as well make sure there are no some problems introduced after the split.

In case of new device having CX24116 or TDA10071, but different tuner than firmware controlled CX14118A, driver must be changed to support new configuration. Or even make new driver if differences are too big. I suspect implementing new .set_frontend() callback is almost everything what is needed. Then add configuration option .tuner_controlled_by_firmware or something like that. There is likely rather similar existing cases. IIRC someone mentioned AF9035/AF9033 firmwares have different versions for different tuners. Also AF9015 uploads firmware to AF9013 demod, external or internal. Still AF9013 driver could upload firmware independently. There is many kind of cases chip/firmware can control other chips. And if you look AF9015/AF9013 and AF9035/AF9033 drivers you can see some examples of splitting drivers even those are many times integrated together. OK, that AF90xx stuff goes to DVB-T side but it is good example of splitting drivers and supporting very wide set of demod/tuner combinations. And it is nice you found CX24116 is sold by two different tuners :) If those tuners are controlled by the driver we can see similar mess than ds3000 + ts2020 or ts2022. At the some point handling different tuner drivers inside one demod driver goes difficult - errors can be done easily and maintaining goes hard. regards Antti -- http://palosaari.fi/ -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to

Re: [PATCH 1/6] m88ds3103, montage dvb-s/s2 demodulator driver
Antti, Mauro, i believe we're all on the same page here and i just want to summarize based on all the discussion so far and if we all agree: 1) ds3000 and ts2020 code split, there are already several strong arguments about it and most of all that it turned out there is reference design with 3rd party tuner that works both with ds3000 and stv090x demodulators. i will take care of this task 2) the result of 1) would be that the following DVB-S2 tuner and demodulator drivers will be able to work in any combination of each other (assuming there is such hardware design available): stb0899*, stv090x*, ds3000, stv6110x*, stb6100* and ts2020. that's good, because it starts to put order, because those are significant part of the DVB-S2 drivers in the kernel 3) not only, because of 2), but in general it's not clear why there is stv6110.* driver, which is for the exact same silicone as stv6110x*, as well stv0900*, which is for the same family of chips as stv090x*. i can help a little here to the degree that i can make all bridge drivers depend on stv6110x* and stv090x* except the driver for one card made by NetUP - there i can just do it in theory, but i can't test and probably break support for it 4) after 1), 2) and if 3) is resolved the only DVB-S2 drivers that will continue to be married to one particular tuner (CX24118A) that will left are cx24116 and tda10071, which for the time being will be left that way until basically there is someone that volunteers to make separate CX24118A driver based on the LG, SHARP and Comtech datasheets that are available in the public domain, for which i gave details in a previous email, and which in my opinion contain sufficient information that task to be made 5) ds3103 and ts2022 support, done in form of a patch respectively to ds3000 driver and ts2020 driver or if ts2022 happens to be very different than ts2020 then ts2022 support be made as separate driver, i guess Max will take this 6) if it's necessary bug fixes, improvements, etc to the shared code between ds3000 and ds3103, but only after review, discussion and argumentation why those changes are actually needed On Fri, Apr 27, 2012 at 11:42 PM, Antti Palosaari cr...@iki.fi wrote: On 27.04.2012 23:21, Konstantin Dimitrov wrote: On Fri, Apr 27, 2012 at 10:55 PM, Antti Palosaaricr...@iki.fi wrote: On 27.04.2012 22:01, Konstantin Dimitrov wrote: Mauro, your reasoning makes sense to me. so, let's split them and at least settle this part of the discussion - i will do as far as my spare time allows, as well make sure there are no some problems introduced after the split. also, in one email i've just sent in answer to Antti there is enough argument why such split, i.e. tuner-pass-through-mode is subject to discussion about CX24116 and TDA10071 drivers too. currently, majority of DVB-S2 demodulator drivers in the kernel are married to particular tuners and there is no split.

So if I use your logic, what happens if CX24118A tuner is not driven by CX24116 or TDA10071 firmware? == it happens we have two drivers, CX24116 and TDA10071 *both* having similar CX24118A tuner driver code inside! Same tuner driver code inside two demods drivers. Could you now understand why we want it split? The reason which saves us having CX24118A tuner driver is that it is inside both CX24116 and TDA10071 firmware. There is mainly two different controlling situation. Most commonly driver controls chip but in some cases it is firmware which is controlling. And I don't see it very important trying always to by-pass firmware control and use driver for that. i got that point, but what happens if tomorrow their is CX24116 or TDA10071 design with tuner different than CX14118A? in fact the LG datasheet i pointed out to you clearly states that for example there is actually such design - case when CX24116 is used with CX24128 tuner instead CX24118A in which case the only way is to bypass the firmware and control the tuner directly. also, isn't it even double bad the current state of CX24116 or TDA10071 drivers - from one side they use 2 firmwares, part of which is doing the same, i.e control the CX24118A and from the other side they depend on proprietary firmware to do something that can be done in open-source code? i don't know, but at least from my point of view if that's not worse than the current status of ds3000 driver, it's at least as wrong as it, i.e. there isn't not only separation of tuner and demodulator code in CX24116 or TDA10071 drivers, but there is not even a code that can allow they to be separated easily, because making CX14118A driver from scratch is task that will need some

I suggest to put the dvb-s/s2 initialize constant data of ds3000 to the seperate files. As i patch ds3103, it has also dvb-s/s2 initialize datas. It will make ds3000 file too long and ugly to review.
