V4L/DVB: gspca - main: Don't use the frame buffer flags · f7059eaa

由 Jean-François Moine 提交于 7月 06, 2010

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: Simplify image building · b192ca98

由 Jean-François Moine 提交于 6月 27, 2010

The image pointer and its length are now in the main structure instead
of in the frame buffer. They are updated on application vidioc_qbuf and
in the URB interrupt function when ending an image.

All PAC7311 specific functions remain in pac7311.c. All PAC7302 specific
functions are moved to pac7302.c. The USB device table is also divided into
two parts. This makes it possible to remove the sensor specific decisions
from different functions and also remove sensor infromation from the USB
device table.

The common functions are just copied to both subdrivers. These common
functions can be separated later to a common file or helper module.
