* | V4L/DVB: gspca - vc032x: Move the first VC0321 settings to sd_init()Jean-François Moine2010-08-021-13/+12
| | | | | | | | | | | | | | | | The first VC0321 settings were done at webcam connection only. They must also be done on resume after suspend. Signed-off-by: Jean-François Moine <moinejf@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | | | | | | | The bit 0x04 of the bridge register 02 (GPIO) is used for audio connection in webcams containing the bridge SN9C105. This patch sets it correctly, according to the presence of an audio device.

* | 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.

* | V4L/DVB: gspca - main: Possible race condition in queue managementJean-François Moine2010-08-021-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
