Hi Mauro, In the patch, you check that the sensor is an OmniVision one, but not the ov9650. So, if the test succeeds, it could also be any of ov9655, ov7660 or ov7670, which could be treated, but will not work, or some other OmniVision sensor. The sensor type is defined by the sensor registers 0x0a and 0x0b. But, if it is enough for you, it is OK for me.

Hi Mauro, I looked again at the USB traces I have with this sensor, and a problem was raised every time I found a webcam with the opposite setting of the powerdown mode. The last webcams I fixed were the Microsoft's VX1000 and VX3000 were the power mode is inverted. Indeed, this change broke most of the other ov7660 based webcams. So, the correct patch is to define the power mode in the device table.

[RESEND] [PATCH 1/2] OMAP1: allow reserving memory for camera
OMAP1 camera driver, when starting up in its videobuf_contig mode, may have problems with allocating dma coherent memory after system memory gets fragmented if there is no dedicated memory declared as a dma coherent memory block associated with the device. To solve this issue, allow for removing a block of memory from system memory early on boot, then, if reserved this way, declare it as the device dedicated dma coherent memory. An example use case on Amstrad Delta will be provided with patch 2/2. Created and tested against linux-2.6.37-rc4.

[RESEND][PATCH for stable 2.6.36 REGRESSION] cx25840: Prevent device probe failure due to volume control ERANGE error]
Resending, since this didn't appear to make its way into in 2.6.36.2. This patch fixes a regression that breaks analog video and audio on boards supported by the ivtv, pvrusb2, cx231xx, and cx23885 drivers. The regression also breaks IR on boards supported by the cx23885 driver. Regards, Andy The volume control scale in the cx25840 driver has an unusual mapping from register values to v4l2 volume control values. Enforce the mapping limits, so that the default volume control setting does not fall out of bounds to prevent the cx25840 module device probe from failing.

[PATCH v18 1/2] MFD: WL1273 FM Radio: MFD driver for the FM radio.
This is the core of the WL1273 FM radio driver, it connects the two child modules. The two child drivers are drivers/media/radio/radio-wl1273.c and sound/soc/codecs/wl1273.c. The radio-wl1273 driver implements the V4L2 interface and communicates with the device. The ALSA codec offers digital audio, without it only analog audio is available. Signed-off-by: Matti J.

This flag is also set using MEDIA_IOC_SETUP_LINK ioctl and setting the flags field would be something like this: media_link_desc.flags |= MEDIA_LINK_ACTIVATED; I'd prefer ACTIVE over ACTIVATED, since this may also be set (and is mostly set) by the user.

Bear in mind that for > most audio the power is a big portion of the control - either the audio > is analogue or it looks like it. What would you think about "ENABLED"? It's simple, quite generic and thus doesn't explicitly suggest what is the exact effect it has on the level of the underlying device. I don't completely like it myself since it would be best to have an adjective (like "active") but there's none for the word enable, so it bears the same issues than "activated".

dvb-apps: update DVB-T intial tuning files for Finland (fi-*)
Moi Christoph, Updates all Finnish channels as today. I accidentally removed first fi-Smedsbole file since that was not generated by my scripts. Actually it is for the autonomy island named Åland [1] between Finland and Sweden. They have even own top level domain - ax. I think correct name for that is ax-Smedsbole instead of fi.

For OMAP1, which is ARMv5 or lower, device memory becomes 'uncacheable, unbufferable' which is luckily what is used for the DMA coherent memory on those platforms - so no technical problem here. However, on ARMv6 and later, ioremapped memory is device memory, which has different ordering wrt normal memory mappings, and may appear on different busses on the CPU's interface. So, this is something I don't encourage as it's unclear that the hardware will work. Essentially, dma_declare_coherent_memory() on ARM with main SDRAM should be viewed as a 'it might work, it might not, and it might stop working in the future' kind of interface. In other words, there is no guarantee that this kind of thing will be supported in the future. -- 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

budget_av and high load
Hello everybody on the list, I have a KNC-1 DVB-S card running under kernel 2.6.36 and mythtv. I experience high load values in top like mentioned ages ago in this thread: http://www.linuxtv.org/pipermail/linux-dvb/2008-June/026509.html. My card has no CI-Module installed and the high load was CI-Module related, so I decided to give it a try and completely disable ciintf_init() in the kernel module which helped a lot. Load decreased by 50-80%. So I decided to add a module parameter to disable ciintf_init() on demand. Here is the diff: 65,69d64 < < int budget_init_ci=1; < module_param_named(init_ci, budget_init_ci, int, 0644); < MODULE_PARM_DESC(init_ci, "Turn on(1)/off(0) ci initializing (default:on)."); < 1519,1520c1514 < if (budget_init_ci) < ciintf_init(budget_av); --- > ciintf_init(budget_av); I don't know if this is useful at all so please be patient with me.

(Resending with reply-all, sorry for that) Hi, > a first, very simplified, linux kernel driver for the Kinect sensor > device is now available, so you now can use it as a ridiculously > expensive webcam with any v4l2 application. Good work!

This is actually precisely the reason why I made sure we had GPLv2 as an option :) > Now the hard part begins, here's a loose TODO-list: > - Discuss the "fragmentation problem": > * the webcam kernel driver and the libusb backend of libfreenect >are not going to conflict each other in practice, but code >duplication could be avoided to some degree; we could start >listing the advantages and disadvantages of a v4l2 backend >opposed to a libusb backend for video data in libfreenct (don't >think in terms of userspace/kernelspace for now). I don't think we should exclusively move over Kinect support to current standard kernel interfaces (v4l, input, ALSA...), as they are too generic and people like to experiment with and use the features of the Kinect to their fullest. However, kernel drivers do have their advantages, and of course people also want to use the Kinect as a standard input device where it makes sense. I think the best solution would be to have a kernel driver that implements the basics of the kinect (v4l RGB video for webcam use, mainly, and possibly a simple depth feed), as well as provides the streaming layer for libfreenect to use (iso packet header parsing and frame reassembly, but no data processing). Libfreenect would hook into this as a backend (the current abstraction is at the USB level but this could be changed) and therefore get the benefits of kernel-side iso handling and streaming (probably 10x less context switching and more reliable performance for loaded systems) while still letting the lib handle configuration and letting us experiment with the different modes and formats without messing with the kernel code. And without libfreenect, users get to use the Kinect as a regular webcam. I'm not sure what this "power" kernel interface would look like, but it could be v4l2 as long as we can make sure we can expose all the Kinect specifics at a lower level (basically weird/compressed/packed frame formats, the timestamps, and raw control commands/responses). Also, I haven't checked, but I assume v4l2 supports select()/poll() for frames (this is critical in order to interoperate with the way libusb does things, for our other subdevices). Another advantage of not exposing all the Kinect functionality at high level via v4l2 methods is that we don't have to duplicate that code in the kernel (otherwise libfreenect would just become one huge switch at the high level to select between doing most everything in the kernel and doing most everything in userspace, and then what's the point). The goal would be a thin kernel driver in libfreenect mode, plus a thick but basic mode for general compatibility with other v4l apps. > * Would exposing the accelerometer as an input device make sense >too? The only reason for that is to use the data in already >existing applications. And what about led and motor? I'm not sure we need an accelerometer kernel driver, but if someone has a use case for accelerometer data delivered via evdev with existing code it could be done. There's not much point in making libfreenect talk to it though, for that subdevice we should just ask libusb to unbind the kernel driver if one gets written. > - Decide if we want two separate video nodes, or a > combined RGB-D data stream coming from a single video device node. > (I haven't even looked at the synchronization logic yet). A combined video stream is hard because the sources aren't framelocked, not to mention the video streams aren't aligned (and as far as I can tell, no, the Kinect's standard firmware cannot either of these, even though its chipset can). I think figuring out how to align things both temporally and spatially belongs squarely in userspace, so the Kinect should show up as two v4l2 devices: one for video, and one for depth. This also lets us play with RGB/IR and depth parameters fully independently (they really are two separate streams) and makes perfect logical sense given how the Kinect hardware is implemented. Audio is still up in the air, but an ALSA driver would of course make sense for general microphone use; once we figure out what we want to do with audio this will become clearer. I suspect that getting echo cancellation to work at all will be near impossible without a hard realtime framework extending outside the kernel (i.e. JA

How to control streaming in non-periodic system ?
Hi, I'm looking for a general solution in camera preview application. When I use the following sequence, there is no problem in normal case. Normally application sleeps in poll and then will be waked up by Camera VSYNC. while (1) { poll DQBUF memcpy to FB QBUF } But sometimes there is non-periodic long delay more than 1sec in application. So before calling poll some buffers has been already passed to outgoing queue. So in a single time quantum(schedule) many memcpy operations are done on FB like: poll -> DQBUF -> memcpy -> QBUF -> poll(no sleep) -> DQBUF -> memcpy... So preview isn't unnatural owing to memcpy without delay. In that case what is a general solution ? In my opinion frame drop can be a solution. So now I changed the sequence as below. open device with non-block flag. while (1) { while (ret != -EAGAIN) { idx = dp_idx; ret = DQBUF(&dq_idx); } if (idx < -1) { poll DQBUF(&idx) } memcpy to FB QBUF } Best regards, Jonghun Han, -- 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
