This patch moves the EXPORT_SYMBOL's from

Video_buf were concerned to allow PCI devices to be used as
video capture devices. This patch extends video_buf features
by virtualizing pci-dependent functions and allowing other
type of devices to use it.
It is still DMA centric, although it may be used also by
devices that emulates scatter/gather behavior or a DMA device

The conversion was generated via scripts, and the result was validated
automatically via a script as well.

- deny activation of streaming capture if overlay is active, apps must disable overlay first
- fix resource handling for overlay
- don't try to stop streaming capture when it's not running
|
|
- add resource management functions
- lock various stuff against each other, mostly vbi capture vs. planar capture
formats, which use the same video dma
- remove old commented out code
- add new "flag" variable to saa7146_formats struct, store the information
if a capture format is planar or packed
- check for return codes at various places

cleanup of the capture buffers. otherwise the buffers were not cleaned up
correctly when a program was killed by CTRL-C, which led to memory corruption

- janitorial fixes (mostly return code handling)
- spelling fixes in Kconfig files
- line breaks to re-formatting

- fix init/exit of vbi capable devices
- add new flag SAA7146_USE_PORT_B_FOR_VBI, so we can distinguish
on which video port to apply the vbi workaround
- add del_timer(...) for vbi capture queue and vbi_read timers,
otherwise the kernel timer schedule oopses
- add vbi device handling for dvb-c cards with analog module
(does not work yet, have to setup the saa7113 decoder differently)

of a per-extension information. This is needed for the DVB-C cards,
which seem to have swapped field order and need to propagate some

Kannst Du das bitte ändern und die EXPORT_SYMBOL*()-Gesichten in ein saa7146_ksyms.c oder wie auch immer kapseln?
"saa7146_core.c" has all dependencies for the "saa7146_core.o" module
(saa7146_core.c and saa7146_i2c.c)
The dependencies for the "saa7146_vv.o" module have been moved from
the source files to "saa7146_vv_ksyms.c", the Makefiles habe been
changed accordingly.
Ok?

Alan Cox reformatted the code to follow his coding style when
he fixed the merge bugs.
This patch now introduces these coding style changes, so
that we don't wipe out his changes with the next patchset.

to a separate "analog-2.4" directory. Main reasons:
- the drivers don't have anything to do with dvb 8-)
- the drivers are already in the kernel (besides the "Hexium" driver)
and don't change that much any more
- the analog drivers rely on the i2c subsystem, which was heavily modified
between 2.4 and 2.5. When making a new DVB patchset I have to work around
these differences every time, which is very annoying

driver subsystem.

TODO: use scatter/gather DMA for clipping informations, too.

use KBUILD_BASENAME for 2.4 instead
some changes to the i2c core to make it work with both 2.4 and late 2.5
kernels (not done yet -- only interesting for analog drivers)
- add MODULE_DEVICE_TABLE to all drivers, so that pci "hotplug" can detect
the devices automatically. Alan Cox says, that we should use this to load
the firmware (not done yet)
- fix the long standing "insmod/rmmod with multiple budget cards" bug -- it
was a double kfree() call...

"dvb-kernel" tree into shape for direct inclusion into the
2.5.x kernel.

based saa7146 cards
- change the initialization order to allow static builds of the mxb driver
|
|
- removed the patches, they are not needed any more. you can now
use a vanilla 2.5.55 kernel
- created a new backport for video-buf and videodev from the 2.5.55
sources
- necessary fixes to the saa7146 driver due to changes in 2.5.55
- the core budget functions are now provided by a module called
"budget-core.o". (otherwise static compilation is not possible...)
- removed #ifdef MODULE crap from all files
Misc.
- "xawtv" (using xv extension) resulted in wrong colors. the problem
is within "xawtv". Gerd Knorr told me, that it'll be fixed in the
next release.
I tested this version with 2.4.20, 2.5.55 (modules) and 2.5.55
(static).

- removed unused variables
- other code clenaups
- corrected H_PIXELS_PAL to 720 (not used for DVB-cards)

(tested on 2.4.18 and 2.5.53 -- the budget driver is
untested, Holger will test it the next week)
saa7146:
- completely separated the saa7146 driver into a core-driver (saa7146.o) and
a video/vbi part (saa7146_vv.o). this allows you to build the budget driver
without av7110 and videodev bloat (see below)
The following thinks have been approved by Holger Waechtler:
av7110 (now ttpci):
- for 2.5.x: removed the av7110 directory and put everything into ttpci.
- removed all budget card support from this driver
- compile and build fixes for the saa7146 changes
ttpci-budget (new):
- for 2.5.x: created a new ttpci-budget directory, added a new driver for
the budget cards
mxb:
- compile and build fixes for the saa7146 changes
Changed the build and compile files for both 2.5.x and build-2.4 of course...

videodev.o dependency,
so we can later split up the av7110 driver into a av7110 and budget card driver.
I tested this on 2.4.18-3 (original RedHat 7.3 kernel) and 2.5.53.
Changes in detail:
saa7146:
- fixed the unitialised timer warnings
- split saa7146.o into saa7146.o and saa7146_vv.o:
all videodev (ie. v4l) related stuff is now encapsulated in saa7146_vv.o.
the extension (ie. mxb or dvb-ttpci) now has to make sure to register the v4l
devices via helper functions provided by saa7146_vv
mxb:
- changes to make the driver compile with the new saa7146 and saa7146_vv parts
- fix the vbi bypass issue for MXBs with saa7146, rev. 1 card
av7110:
- changes to make the driver compile with the new saa7146 and saa7146_vv parts
- some changes related to the upcoming av7110 <=> budget splitup, but they are
commented out
- changed the saa7146 PAL values to experimental values that look good to me, but
kept the old values as a comment. where are the original values from? there is
a big black border on most channels on the left side which annoyed me...
- changed from video/generic_usercopy() to dvb_usercopy() and put this into the
source code, not into compat.c
- moved the crc_32* stuff from compat.c to the source file where it is used
- now compat.[ch] was removed completely, all references were deleted from
all other files.
other:
- updated the README and TODO files
- changed "makelinks" to remove alps_bsru6 stuff from kernel when making the symlinks
- fixed the build files in "build-2.4"
- fixed all other files needed for 2.5.x kernel build
