* V4L/DVB: dvb: add support for kworld 340u and ub435-q to em28xx-dvbJarod Wilson2010-08-023-0/+62
| | | | | | | | | | | | | | | | | This adds support for the KWorld PlusTV 340U and KWorld UB345-Q ATSC sticks, which are really the same device. The sticks have an eMPIA em2870 usb bridge chipset, an LG Electronics LGDT3304 ATSC/QAM demodulator and an NXP TDA18271HD tuner -- early versions of the 340U have a a TDA18271HD/C1, later models and the UB435-Q have a C2. The stick has been tested succesfully with both VSB_8 and QAM_256 signals. Its using lgdt3304 support added to the lgdt3305 driver by a prior patch, rather than the current lgdt3304 driver, as its severely lacking in functionality by comparison (see said patch for details).

* V4L/DVB: gspca - main: Don't use the frame buffer flagsJean-François Moine2010-08-029-106/+58
| | | | | | | | | | | | | | | | | | This patch fixes possible race conditions in queue management with SMP: when a frame was completed, the irq function tried to use the next frame buffer. At this time, it was possible that the application on an other processor updated the frame pointer, making the image to point to a bad buffer. The patch contains two main changes: - the image transfer uses the queue indexes which are protected against simultaneous memory access, - the image pointer which is used for image concatenation is only set at interrupt level. Some subdrivers which used the image pointer have been updated.

| | | | | | | | | | | | | | | The problem may occur with SMP: - a frame is completed at interrupt level (in gspca_frame_add with packet_type == LAST_PACKET, - just after clearing the bit V4L2_BUF_FLAG_QUEUED and before setting the bit V4L2_BUF_FLAG_DONE, on the other processor, the application tries to requeue the same frame buffer, - then, the qbuf function succeeds because ALL_FLAGS are not set. The fix sets and resets the two flags in one instruction.

| | | | | | | | | | | | | | As pointed by Christoph Egger <siccegge@stud.informatik.uni-erlangen.de>, The config Option DVB_DIBCOM_DEBUG was dropped while removing the dibusb driver in favor of dvb-usb in 2005. However it remaind existant at some places of the kernel config. Instead of just removing the debug capability, the better is to just remove the bad dependency, making the modprobe function always visible.

* V4L/DVB: IR/mceusb: more streamlining of device initJarod Wilson2010-08-021-16/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Spent a while last night getting device initialization packet captures under Windows for all generations of devices. There are a few places where we were doing things differently, and few things we were doing that we don't need to do, particularly on gen3 hardware, and I *think* one of those things is what was locking up my pinnacle hw from time to time -- at least, its been perfectly well behaved every time its been plugged in since making this change. First up, we're adding a bit more to the gen1 init routine here. Its not absolutely necessary, the hardware works the same both with and without it, but I'd like to be consistent w/Windows here. Second, DEVICE_RESET is never called when initializing either of my gen3 devices, its only called for gen1 and gen2. The bits in the gen3 init after removing that, are safe (and interesting) to run on all hardware, so there's no more gen3-specific init done, there's instead a generic mceusb_get_parameters() that is run for all hardware. Third, the gen3 flag isn't needed. We only care if hardware is gen3 during probe, so I've dropped that from the device flags struct. Successfully tested on all three generations of mceusb hardware.

* V4L/DVB: v4l2-dev: fix memory leakAnatolij Gustschin2010-08-021-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Since commit b4028437876866aba4747a655ede00f892089e14 the 'driver_data' field resides in device's struct device_private which may be allocated by dev_set_drvdata() if device_private struct was not allocated previously. dev_set_drvdata() is used in video_set_drvdata() to set the driver's private data pointer in v4l2 drivers. Setting the private data _before_ registering the v4l2 device results in a memory leak since __video_register_device() also calls video_set_drvdata(), but after zeroing the device structure. Thus, the reference to the previously allocated device_private struct goes lost and a new device_private will be allocated. All v4l drivers which call video_set_drvdata() _before_ calling video_register_device() are affected. The patch fixes __video_register_device() to preserve previously allocated device_private reference. Caught by kmemleak.

* V4L/DVB: uvcvideo: Support menu controls in the control mapping APILaurent Pinchart2010-08-024-28/+110
| | | | | | | | | | | | | The UVCIOC_CTRL_MAP ioctl doesn't support menu entries for menu controls. As the uvc_xu_control_mapping structure has no reserved fields, this can't be fixed while keeping ABI compatibility. Modify the UVCIOC_CTRL_MAP ioctl to add menu entries support, and define UVCIOC_CTRL_MAP_OLD that supports the old ABI without any ability to add menu controls.
