Problem with v4l tree and kernel 2.6.33
Kernel 2.6.33 just went stable. I compiled, installed, reboot. Grabbed a fresh v4l tree, menuconfig'ed, compiled and installed. Upon loading I got Invalid module format for each file. For example: WARNING: Error inserting dvb_ttpci (/lib/modules/2.6.33.amd64-x2.022410.1/kernel/drivers/media/dvb/ttpci/dvb-ttpci.ko): Invalid module format I then did a distclean, make, make install: Updating/Creating .config Preparing to compile for kernel version 2.6.33 VIDEO_TVP7002: Requires at least kernel 2.6.34 RADIO_SAA7706H: Requires at least kernel 2.6.34 Created default (all yes) .config file Again, Invalid module format. I then confirmed that .version matched my 2.6.33 kernel: test:/v4l-dvb$ cat v4l/.version VERSION=2 PATCHLEVEL:=6 SUBLEVEL:=33 KERNELRELEASE:=2.6.33.amd64-x2.022410.1 test:/v4l-dvb$ uname -r 2.6.33.amd64-x2.022410.1 So... I'm at a loss why this is happening. Any ideas? kernel 2.6.33 gcc (Debian 4.4.2-9) 4.4.3 20100108 (prerelease) v4l tree 37581bb7e6f1 tip Thanks in advance. -- 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

I don't think this is less work than copying the header file from the
Kernel. Test building under all versions of the Kernel headers that
exist to make sure something isn't missed isn't possible. It really is
easier just to sync the header file up.
The reason for this is that I want to avoid carrying a copy of a dir
from some other tree, with all getting stale and needing sync all
the time issues that come with that, not to mention chicken and egg
problems in the case of new formats which simultaneously need to be
added to both libv4l and the kernel.
Worst case is that if it is stale then it won't build since it depends
on fancy new feature XYZ. But, at least it won't build on all systems
instead of randomly breaking based on installed kernel headers
version.
For example often I add support for V4L2_PIX_FMT_NEW_FOO to libv4l, before it
hits any official v4l-dvb kernel tree, with the:
Please don't add features to releases before they are merged with
Linus. It would suck to ship a copy of libv4l that has a different
idea of structs or constants then the upstream Kernel.
Note the only thing added is a V4L2_PIX_FMT_xxx define, IOW this makes libv4l
recognize (and convert from) a new video format, which is to be generated
by a going upstream soon driver. With older kernels this won't make any
difference as those don't generate that format.
Approach this works fine, if I were to carry an include tree copy, that would
now need to become a patched include tree copy, and with the next sync I then
need to ensure that any needed patches are either already in the sync source,
or applied again.
Or just fix it upstream with #ifdef __KERNEL__ tags once and for all,
right?
I wasn't even talking about #ifdef __KERNEL__ issues, although yes those
exist too.

Hans

RE: Requested feedback on V4L2 driver design
Laurent, Some additional information from the syslink team. Yes, the current Notify code is indeed going over the kernel mailbox code. You can find this code in drivers/dsp/syslink/notify_ducatidriver/notify_ducati.c. We have already pushed some mailbox patches specific to the new mailbox register set in OMAP4/Netra to kernel. These patches are available starting in 2.6.33. On our tree, we currently have some custom patches some of which were pushed to upstream and in the process of getting rolled into the upcoming 2.6.34 releases.

From the code available currently on omapzoom, our plans are to eventually have only the Notify module in kernel-space. All the other code in multicore_ipc will actually move to user-side. The Notify module gives additional functionality over the basic mailbox driver to abstract the single physical event into multiple logical events. This enables multiple clients (one of which is the DSS driver) to use the single physical interrupt for multiple different purposes in a fully modular manner. We will ensure that the kernel-side Notify module is fully integrated into the kernel in the proper way and still meets our functionality requirements, taking feedback from the community into account. We are also making several changes in the APIs for all modules to make them much easier to use. A lot of the complexity as seen by the user will vanish underneath. This is still under progress, so it's not out on omapzoom yet, but will definitely be done. As soon as this is done, we will work on moving most of the modules (except Notify) fully from kernel-user space. Once our kernel-user work has at least gone far enough ahead to allow us to make a design proposal, we will push it out for review to get your valuable feedback. I have also looped in the TI engineers who have worked on and pushed out the omapzoom SysLink code.

v4l-utils repo progress report
Hi All, I've been working on and off on the new v4l-utils git repo. I've just pushed my latest work, some restructuring of the files under the utils dir, and I've replaced the old Makefiles which were meant for compilation inside the v4l-dvb hg tree with new ones which work for standalone compilation. I've ended up with including copies of a few recent kernel headers as that indeed was the easiest way. I'm using plane (GNU) make for now, as that seems to work very well and I very much like the clean and simple Makefiles this has resulted in (as opposed to the zillion line makefiles generated by autotools). And yes the Makefiles take into account that libsysfs and / or qt might not be installed and do not build the relevant bits when they are missing.

It even will work, but I'm wondering if I would have to buy such card, to get it through. Thanks for your time to review that. As said, I would prefer to see all OEMs _not_ following Philips/NXP eeprom rules running into their own trash on GNU/Linux too. Then we have facts. That is much better than to provide a golden cloud for them. At least I won't help to debug such later ... If you did not manage to decipher all OEM eeprom content already, just let's go with the per card solution for now. Are you aware, that my intention is _not_ to spread the use of random and potentially invalid eeprom content for some sort of such auto detection? The other solution is not lost and in mind, if we should need to come back to it and are in details. Preferably the OEMs should take the responsibility for such. We can see, that even those always doing best on it, can't provide the missing informations for different LNA stuff after the Hauppauge/Pinnacle merge until now. If you claim to know it better, please share with us. I'm not claiming anything, and to be honest, I have no idea what you're talking about. Never mind. I'll keep you posted when it comes to further progress on such and input_init2 is the needed better solution. We have a whole chain of previously latest different Asus cards supported by PCI subsystem identification, only this single one fails on it and needs eeprom bogus detection. On the Pinnacle stuff we have a complete mess, concerning LNAs, likely even different LNAs, no LNA at all, different remotes etc., all with the same PCI subsystem. You can't even detect the LNA type, if you would know the meaning of the complete eeprom content, since some to us unknown check-sums are in use for that. That I try to tell.

But videobuf doesn't need it and it makes no sense to me either unless it is for symmetry with VIDIOC_QBUF. Strictly speaking QBUF doesn't need it either, but it is a good sanity check. Can I remove the statement in the spec that memory should be set for DQBUF? The alternative is to add a check against the memory field in videobuf, but that's rather scary. In that case I would remove it for QBUF as well, and state that the memory field must be ignored by drivers (but should they fill it when returning from QBUF/DQBUF ?) Agree. It seems that the memory field is not useful at all in the struct v4l2_buffer if a same process does reqbuf, qbuf, dqbuf and querybuf. In the current multi-plane buffer proposal, the memory field is required in querybuf, qbuf and dqbuf for the v4l2-ioctl.c code to be able to determine whether the planes array should be copied from/to user along with the buffer. Just wanted to add another view to the problem, as multiplanes are accepted yet of course. Thanks for the reminder. I'm not against keeping the requirement for applications to set the memory field in the v4l2_buffer structure. QBUF and DQBUF should behave the same way though, they should both require the field to be set or not require it at all. As for the REQBUF, I've always thought it'd be nice to be able to ask the driver for the recommended number of buffers that should be used by issuing a REQBUF with count=0... How would the driver come up with the number of recommended buffers ? -- Regards, Laurent Pinchart -- 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

Multi-core design OMAP3 was already a dual-core system, OMAP4 (I assume all this is about the OMAP4 processors family) seems to push the concept one step further. With its heterogeneous multi-core design (ARM master CPU and slave DSPs), the OMAP architecture delivers high performances at the cost of higher development time and effort as users need to write software for completely different cores, usually using different toolchains. This is in my opinion a good (or at least acceptable) trade-off between CPU power, development time and power consumption (DSPs being more efficient at signal processing at the cost of a higher development complexity). I'm a bit puzzled, however, by how the VPSS MCU will help improving the situation compared to the OMAP3 design. The VPSS MCU will provide an API that will expose a fixed subset of the hardware capabilities. This is only a guess, but I suppose the firmware will be fairly generic, and that TI will provide customized versions to big customers tailored for their needs and use cases. The official kernel drivers will then need to be changed, and those changes will have no chance to be accepted in the mainline kernel. This will lead to forks and fragmentation of the developers base among the big players in the embedded markets. What will be the compensation for that ? How will the VPSS MCU provide higher performances than the OMAP3 model ? The firmware on the VPSS MCU will be able to configure/control all of the functionality that the VPSS MCU has and will be the same for all customers. The only part that may change is the proxy driver of the firmware. The proxy driver is the piece that will be responsible for taking the commands from the driver and telling the firmware to execute the operation. As the proxy is the tip of the firmware iceberg, it will be all the Linux driver will care about. Whether the firmware backend is able to configure and control all of the functionality that the VPSS MCU offers is then irrelevant, as the Linux driver will have no way to access that backend directly. Is my understanding correct ? The initial version of the proxy will support all the standard V4L2 operations. As new operations (such as on the fly video scaling) are added to the V4L2 API the firmware may require an update to the proxy driver to handle these requests, but the underlying code will remain the same. Different proxy versions will need different version of the Linux driver. That's where fragmentation of the developers base come into play, and that's the part that worries me. For customers who wish to use features of the VPSS that are not supported by the current V4L2 APIs there are OpenMax components being developed that can also talk to the VPSS and support the full set of features of the VPSS. These components allow for additional use cases such as transferring data directly from other processing blocks such as the DSP to the VPSS without ever returning to the host processor (tunneling). However, the OpenMax API does not integrate with most existing software such as applications that use V4L2 drivers for video capture and display. So the firmware backend will expose all its features through OpenMax, and the proxy will expose a V4L2-like API based on the firmware backend ? In that case why do we need a proxy at all, why can't the Linux driver access the firmware backend directly and configure it the way it sees fit ? My understanding is that both the backend (for OpenMax) and the proxy will be accessed through

Hi Chase, On Tuesday 16 February 2010 14:00:11 Maupin, Chase wrote: Laurent, To follow up with some of the comments I made before I got additional clarification about the commands supported by the proxy driver running on the VPSS MCU. The proxy will support all of the commands used by V4L2 as well as those proposed extensions to V4L2 that Hans has mentioned. Basically, the list of commands supported at initial release is not only those required today, but a full set for all the features of the VPSS. In this was as new APIs are added to V4L2 the support for those features will already be supported by the VPSS MCU proxy driver. Thank you for the clarification. A few things are still uncleared to me, as stated in my previous mail (from a few minutes ago). My main question is, if the VPSS API is full-featured and accessible from the master CPU, why do we need a proxy driver in the firmware at all ? As for the license of the firmware this is still being worked. It is currently under TI proprietary license and will be distributed as binary under Technical Software Publicly Available (TSPA) which means it can be obtained by anyone. If you feel that source code is required for the firmware at launch to gain acceptance please let us know and we can start working that issue. I think it would definitely help keeping the Linux driver and the VPSS firmware in sync if the VPSS firmware source was available. The firmware source code could even be distributed along with the Linux driver. By the way, will the firmware be loaded at runtime by the driver, or will it be stored internally in the chip ? -- Regards, Laurent Pinchart -- 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

Looks like this should be in mach-omap2/devices.c instead if it's all

[Hiremath, Vaibhav] For sure it's being used for OMAP2/3 and if I understand
correctly OMAP4 also uses it.
