- add SAA7146_ISR_CLEAR
- use those consistently in the ttpci driver
|

breaks compilation with older kernels for dvb-ttpci
|
|
- sparse annotiations (viro)
- NULL noise removal (viro)
- #if where #ifdef should've been (saa7146) (viro)
- convert private ABS() to kernel's abs() (rddunlap)
- dvb_register_i2c_device() locking fix for -ENOMEM (akpm)
- dvb_register_i2c_bus() locking fix for -ENOMEM (akpm)

definition of memory on some esoteric platform

necessary to support big-endian machines (thanks to Wolfram Joost)
|

work reliably yet, though
|

overlay video in one case
|
|
- restrict S_FBUF ioctl to CAP_SYS_ADMIN or CAP_SYS_RAWIO
- don't refuse setting S_FBUF when overlay is active
(changes become visible with the next update)

the device lock
- this fixes the "in_atomic():1, irqs_disabled():1" warnings in the syslog

interrupted by a streaming capture any more. So:
- revamp video_begin()/video_end(), saa7146_start_preview()/saa7146_stop_preview
- clean up a lot of mess around the usage of these functions
- allow overlay to be suspended by streaming capture again, if ressources are available
|
|
- 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

(bug catched by new resource management)

not work
- make sure to disable the right video dma at capture stop
|
|
severe memory damage can occur...
|
|
|
|
- fix problems caused by changes in ioctl definitions
|
|
- deny usage of planar formats for video overlay
- more intelligent checks in VIDIOC_STREAMON and VIDIOC_STREAMOFF
- fix read() capture while overlay is 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
|
|
cleared the various capture queue and has shut down capturing
(Thanks Gerd for explaining the pitfalls here!)
|
|
- more video/vbi open/release fixes
|
|
capture code on device closure
- change minimal picture size to 48x32 just like other drivers
|
|
sanity checks of the arguments (if a bad pagetable is created,
unpredictable thinks can happen. trust me... ;-)
- follow this change for the several uses
|
|
which were commented out anyway
- fix one typo
|
|
- janitorial fixes (mostly return code handling)
- spelling fixes in Kconfig files
- line breaks to re-formatting
|

V4L2_FIELD_ALTERNATE vs. V4L2_FIELD_INTERLACED captures
|
|
- fix pgtable_build_single, it should work for all kinds of
buffers (system memory (kernel/user) and gfx-memory)
- add/change some debug messages
|

to Adrian Bunk <bunk@fs.tum.de> for reporting this)
[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

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?

to different frames were sometimes mixed)
- 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
