- fix pgtable_build_single, it should work for all kinds of
buffers (system memory (kernel/user) and gfx-memory)
- add/change some debug messages

[V4L] - set debug verbosity to 0 for hexium_gemini and hexium_orion drivers
[V4L] - make hexium_gemini and hexium_orion drivers depdend on i2c module
[V4L] - make saa7146 module depend on hexium_gemini and hexium_orion drivers
[V4L] - let the saa7146 i2c bus report itself as I2C_ADAP_CLASS_TV_ANALOG

for an even frame to start with, not an odd frame. This makes applications
happy that expect this (ie. tvtime), but don't specify the correct mode
instead. We behave now like bttv...

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
video4linux specific stuff for the analog module to work.

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?

- first try to get alternating field capture running
- add/change some debug messages
|
|
there are no overlay informations.
|
|
- change saa7146_vv.h the way described earlier
- follow these changes in budget-av and hexium driver

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.

- if the analog module is detected, the saa7113 is initialized and
some more v4l2 ioctls are available. you can use "xawtv" now to
switch between "dvb" and "analog" input. when you are one the
"analog" input, you can tune in analog channels with the cursor
keys via v4l2.
currently, this is a big hack -- tuning is not mutually exclusive,
so "szap" and v4l2 tuning can interfere with each other. the
demodulator address is hardcoded to 0x09.
Other changes:
- changed the saa7146 ioctl parameters, give out the data of the
current device open "fh" (=> "file handle"), not the pointer to the
device structure "dev". It is "dev = fh->dev".
Some stuff does not work:
- analog audio does not work. does the msp3400 need to be reprogrammed?
- one field is "missing", so the picture is very bad and
capturing does not work neither. this needs to be investigated by
looking at the programming the windows driver uses for the saa7146

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.

it compile again under both 2.5 and 2.4.
|

TODO: use scatter/gather DMA for clipping informations, too.
|
|
- add some ifdef magic into i2c drivers (mxb/analog drivers only)
- shuffle around includes, so that "dvb_compat.h" is included after
all other include files
- fix a warning in saa7146 i2c code
|
|
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...

makelinks: adjust the script for the upcoming kernel patches
driver.mxb: prevent the tuner module from probing unnecessary i2c addresses
getlinks: put symlinks for the header files to the right place(TM)
videodev.c: add a verbose error message just for the case that a user
has compiled the v4l module into the kernel
media/Kconfig: the dpc driver does not the tuner module
saa7146_hlp.c: honour the swapped field order for av7110 based cards
in capture mode, too
saa7146_video.c: add some verbose messages for the v4l2 controls
mxb.c: hopefully fix the detection and initialization of the sound arena module

- sync Kconfig and Makefiles with 2.5.65
- fix various things in saa7146 because of latest v4l changes in 2.5.65
- makelinks: removed the compat module from the 2.5.x build process
- makelinks: removed the linkage of ttusb and bt8xx -- enable this again for
the next patches, when ttusb is more stable and the bt8xx related patches
have been applied by Gerd Knorr
- dvb: removed the compat module from the 2.5.x build process, added #ifdefs
around the inclusion of compat.h. this was necessary because having compat
code in the newest 2.5.x kernel is awkward.
- dvb: move around of dvb_usercopy again. because I removed the compat module
from the 2.5.x build process, dvb_usercopy had to be moved to another file
- dvb: change MOD_*_USE_COUNT to module_get/module_put in various files,
but I'm not sure if I did this right. please review these changes.
- dvb: removed the crc32 code from dvb_demux.c, because it's in compat.c, too.
- dvb: removed some cruft from dvd_i2c.c, which is present in compat.h
- all files: apply small fixes to reflect the new location of some header
files

- Moved some generic stuff from budget-core.c to saa7146_core.c where it belongs
----------------------------------------------------------------------

mxb: prevent helper modules to probe on unknown i2c-busses. (for example on a
Matrox gfx card)

- V4L2_PIX_FMT_YUV422P: YUV 4:2:2 planar (Y-Cb-Cr)
- V4L2_PIX_FMT_YVU420: YVU 4:2:0 planar (Y-Cb-Cr)
- V4L2_PIX_FMT_YUV420: YUV 4:2:0 planar (Y-Cb-Cr)
Planar modes don't suffer from the saa7146 byte swap bug, so we
can deliver the formats needed by various video encoders, like "mp1e"
or "nvrec".
Added some notes to the TODO file.

the modules will oops with 2.5.63.

based saa7146 cards
- change the initialization order to allow static builds of the mxb driver
|
|
- Fix various warnings against 2.5.63 (export-objs has been removed)
- Fix Kconfig/Makefiles
- add the "dpc7146" driver for the analog Philips reference design
- Removed unnecessary "Config.in"
|

the other files again.
|
|
|
|
- clean up the mxb driver and it's helper modules (rename the
structures, add GPL license to the appropriate files, c99
initialisers)
- fix 2.5.55 "module insertion causes bug in kobject.o" issue
- fixed missing exported symbols in budget-core
|
|
|
|
- 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).

can do this much better. We now simply register one pci driver for
every extension and are done with it -- if a device actually exists, the
pci subsystem calls us back. That's it.
Warning: this triggers a bug in the 2.5.x module subsystem -- you should
*not* use the driver.av7110 script and modprobe the driver. You can
a) build your kernel staticall
b) insert the modules one by one with *insmod*
I already filed a bug report to lkml.
Fixed a bug in Kconfig which prevented the saa7146 modules from being build.
