When the platform device bound to the media device driver is probed all other entity drivers need to be already in place and initialized. If any of them is not, fail the media device probe and return an error indicating we need to be retried once any new driver gets registered. The media device driver probe will not succeed until there are available all needed sub-drivers, as specified in the platform data. While at it, make sure the s5p-csis module (MIPI-CSI receiver driver) does not get unloaded when in use, by guarding its usage with try_module_get/module_put. This patch is a prerequisite for adding the device tree support. It now also allows again to unbind/bind the driver at runtime from user space via sysfs.

This routine is called from 'video->encode' function (which translates to either 'uvc_video_encode_bulk' or 'uvc_video_encode_isoc') in 'uvc_video.c'. As, the 'video->encode' routines are called with 'queue_irqlock' already held, so acquiring a 'queue_irqlock' again in 'uvc_queue_next_buffer' routine causes a spin lock recursion.

This was apparently originally used with the Medion Digitainer box, but is now sold separately without any Digitainer labeling. A peculiarity of this remote is a scrollwheel in place of up/down buttons. Each direction is mapped to 8 different scancodes, each corresponding to 1..8 notches, allowing multiple notches to the same direction to be transmitted in a single scancode. The driver transforms the multi-notch scancodes to multiple events of the single-notch scancode. (0x70..0x77 = 1..8 notches down, 0x78..0x7f = 1..8 notches up) Since the scrollwheel scancodes are the same that are used for mouse on some other X10 (ati_remote) remotes, the driver will now check whether the active keymap has a keycode defined for the single-notch scancode when a mouse/scrollwheel scancode (0x70..0x7f) is received. If set, scrollwheel is assumed, otherwise mouse is assumed. This remote ships with a different receiver than the already supported Medion X10 remote, but they share the same USB ID. The only difference in the USB descriptors is that the Digitainer receiver has the Remote Wakeup bit set in bmAttributes of the Configuration Descriptor. Therefore that is used to select the default keymap. Thanks to Stephan Raue from OpenELEC (www.openelec.tv) for providing me both a Medion X10 Digitainer remote+receiver and an already supported Medion X10 remote+receiver. Thanks to Martin Beyss for providing some useful information about the remote (including the "Digitainer" name). This patch has been tested by both of them and myself.

This patch makes it work again, and updates it to the latest V4L2 frameworks (except for videobuf2). It passes the v4l2-compliance tests and it now handles suspend/resume correctly. Several custom controls are replaced by new standard controls, only the USB_ALTERNATE control remains. Tested with the Hanse HVS-CM500PC USB microscope.

This generates an external abort on non-linefetch fault, triggering a fatal kernel oops. We can't always prevent preview engine stop failures (they can for instance be caused by a sensor crash), but we can improve the system reliability by refusing to start streaming on a pipeline that contains the preview engine if it failed to stop. The driver will then eventually reset the ISP (when all applications will have closed their file handles related to OMAP3 ISP device nodes), making the ISP usable again.

If the parameters are being changed when the interrupt handler is called, it just delays applying the parameters until the next frame. If an application modifies the parameters for every frame, and the preview engine interrupt is triggerred synchronously, the parameters are never applied to the hardware. Fix this by storing new parameters in a shadow copy, and switch the active parameters with the shadow values atomically.

Recently Rémi Denis-Courmont brought up the issue by proposing a patch to convert the enums to unsigned: This sparked a long discussion where another solution to the issue was proposed: two sets of IOCTL structures, one with __u32 and the other with enums, and conversion code between the two: Both approaches implement a complete solution that resolves the problem. The first one is simple but requires assuming enums and __u32 are the same in size (so we won't break the ABI) while the second one is more complex and less clean but does not require making that assumption. The issue boils down to whether enums are fundamentally different from __u32 or not, and can the former be substituted by the latter. During the discussion it was concluded that the __u32 has the same size as enums on all archs Linux is supported: it has not been shown that replacing those enums in IOCTL arguments would break neither source or binary compatibility. If no such reason is found, just replacing the enums with __u32s is the way to go. This is what this patch does. This patch is slightly different from Remi's first RFC (link above): it uses __u32 instead of unsigned and also changes the arguments of VIDIOC_G_PRIORITY and VIDIOC_S_PRIORITY.

The driver exposes the sensor as three subdevs, pixel array, binner and scaler --- in case the device has a scaler. Currently it relies on the board code for external clock handling. There is no fast way out of this dependency before the ISP drivers (omap3isp) among others will be able to export that clock through the clock framework instead.

But some drivers, particularly USB drivers, may want to prevent the core from taking the lock for specific ioctls, particularly buffer queuing ioctls. The reason is that certain commands like S_CTRL can take a long time to process over USB and all the time the core has the lock, preventing VIDIOC_DQBUF from proceeding, even though a frame may be ready in the queue. This introduces unwanted latency. Since the buffer queuing commands often have their own internal lock it is often not necessary to take the core lock. Drivers can now say that they don't want the core to take the lock for specific ioctls. As it is a specific opt-out it makes it clear to the reviewer that those ioctls will need more care when reviewing.

This also allows a driver to disable certain ioctls based on the capabilities of the detected board, something you can't do today without creating separate v4l2_ioctl_ops structs for each new variation. For the most part it is pretty straightforward, but for control ioctls a flag is needed since it is possible that you have per-filehandle controls, and that can't be determined upfront of course.

Mark this ioctl as invalid if the board doesn't support it. This fixes an issue with S_HW_FREQ_SEEK in combination with priority handling: since the priority check is done first it could return -EBUSY, even though calling the S_HW_FREQ_SEEK ioctl would return -ENOTTY. It should always return ENOTTY in such a case.

Those drivers that already used core locking have this flag set explicitly, except for some drivers where it was obvious that there was no need to serialize any file operations other than ioctl. The drivers that didn't need this flag were: drivers/media/radio/dsbr100.c drivers/media/radio/radio-isa.c drivers/media/radio/radio-keene.c drivers/media/radio/radio-miropcm20.c drivers/media/radio/radio-mr800.c drivers/media/radio/radio-tea5764.c drivers/media/radio/radio-timb.c drivers/media/video/vivi.c sound/i2c/other/tea575x-tuner.c The other drivers that use core locking and where it was not immediately obvious that this flag wasn't needed were changed so that the flag is set together with a comment that that driver needs work to avoid having to set that flag. This will often involve taking the core lock in the fops themselves. Eventually this flag should go and it should not be used in new drivers. There are a few reasons why we want to avoid core locking of non-ioctl fops: in the case of mmap this can lead to a deadlock in rare situations since when mmap is called the mmap_sem is held and it is possible for other parts of the code to take that lock as well (copy_from_user()/copy_to_user() perform a down_read(&mm->mmap_sem) when a page fault occurs). It is very unlikely that that happens since the core lock serializes all fops, but the kernel warns about it if lock validation is turned on. For poll it is also undesirable to take the core lock as that can introduce increased latency. The same is true for read/write. While it was possible to make flags or something to turn on/off taking the core lock for each file operation, in practice it is much simpler to just not take it at all except for ioctl and leave it to the driver to take the lock. There are only a handful fops compared to the zillion ioctls we have. I also wanted to make it obvious which drivers still take the lock for all fops, so that's why I chose to have drivers set it explicitly.

That's true for the other places they are called and it is what subdrivers expect. Quite a few will unlock the usb_lock in stop0 while waiting for a worker thread to finish, and if usb_lock isn't held then that can cause a kernel oops. The other problem is that a worker thread needs to detect that it has to halt due to a suspend. Otherwise it will just go on looping. So add tests against gspca_dev->frozen in the worker threads that need it. Hdg, 2 minor changes: 1) The finepix device is ok with stopping reading a frame halfway through, so add frozen checks in all places where we also check if we're still streaming 2) Use gspca_dev->dev instead of gspca_dev->present to check for disconnect in all touched drivers. I plan to do this everywhere in the future, and most relevant lines in the touched drivers are already modified by this patch.

This causes a problem with stream_off calling sd_stop0 a second time when the device handle is closed. This is fixed by setting gscpa_dev->streaming to 0 on disconnect. Note that now stream_off will never be called on a disconnected device, and the present check can thus be removed from stream_off.

Bit 0 selects between truncation or rounding in the quantization phase of the compression, since rounding generally gives better results it should thus always be 1. This patch also corrects the quality percentages which belong to the 4 different settings. Last this patch removes the different reg 8 defaults depending on the sensor type. Some of them where going for a default quality setting of 50%, which generally is not necessary in any way and results in poor image quality. 75% is a good default to use for all scenarios.

BRC is needed to not run out of bandwidth with higher quality settings independent of the sensor. Also only automatically adjust BRC, and don't adjust the JPEG quality control automatically, as that is not needed and leads to ugly flashes when it is changed. Note that before this patch-set the quality was never changed either due to the bugs in the quality handling fixed in previous patches in this set.

At which point it will make more sense to have the ctrl_handler in gspca_dev then to have it in the subdrivers. Lets move it there now, to avoid a lot of work to move it later.

However, that was very confusing since if you play the audio from the device (e.g. through arecord -D ... | aplay) then no sound would play unless you had the radio device open at the same time, even though there is no need to do anything with that node. On the other hand, the actual suspend/resume functions didn't do anything, which would fail if you *did* have the radio node open at that time. So: - remove autosuspend (bad idea in general for USB radio devices) - move the start/stop out of the open/release functions into the resume/suspend functions.

There were also a few minor problems with dbg_g/s_register that have been resolved. The mxb/saa7146 driver now passes the v4l2_compliance tests.

So it has been removed. Also fixed some incorrect entries in the input table. This driver now passes v4l2-compliance.

However, commit c53c2549333b340e2662dc64ec81323476b69a97 that added the new v4l2_subscribed_event_ops introduced a regression: while the code still queued that initial event the __v4l2_event_queue_fh() function was modified to ignore such requests if sev->elems was 0 (meaning that the event subscription wasn't finished yet). And sev->elems was only set to a non-zero value after the add operation returned. This patch fixes this by passing the elems value to the add function. Then the add function can set it before queuing the initial event.

DVB-T2 channels instead work properly. This patch fixes the problem by changing the condition to break out from the wait lock loop in the "search" function of the cxd2820r demodulator from FE_HAS_SIGNAL to FE_HAS_LOCK. As a consequence, the "search" function of the demodulator driver now returns DVBFE_ALGO_SEARCH_SUCCESS only if the frequency lock is successfully acquired. This behavior seems consistent with other demodulator drivers (e.g. stv090x, hd29l2, stv0900, stb0899, mb86a16). This patch has been successfully tested with DVB-T and DVB-T2 signals, on both PC and the mipsel STB running Enigma2. No apparent side effect has been observed on PC applications like Kaffeine. DVB-C is not available in my country so it's not tested.

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.

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.

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.

As the UVC control is not marked as auto-update, the button bits are set but never reset. A pan reset that follows a tilt reset would thus reset both pan and tilt. Fix this by not caching the control value of write-only controls. All standard UVC controls are either readable or auto-update, so this will not cause any regression and will not result in extra USB requests.

We may not yet have all the needed keymaps, in which case a wrong keymap may be used. This happened with Medion X10 OR2x remotes before the keymap for them was added, causing the ati_remote driver to select the Medion Digitainer keymap instead. Unfortunately, the Medion Digitainer keymap doesn't have the standard X10 up/down scancodes assigned to KEY_UP and KEY_DOWN keycodes, making wrongly assigned remotes mostly unusable. Add the regular KEY_UP and KEY_DOWN scancodes to the Medion X10 Digitainer keymap, making any Medion remote mostly usable even when wrongly used with that keymap (standard buttons, such as up/down/left/right, 0-9, play/stop/pause, have the same scancode in all the X10 remotes).
