Fixed regression reported by Peter Holik:
Image grabbing failed because of invalid config option
VIDEO_V4L1_COMPAT. Should be CONFIG_VIDEO_V4L1_COMPAT.

Just a few adjustments were required on those drivers to be V4L2 compliant.

This patch moves the EXPORT_SYMBOL's from

functions.

From: Mauro Carvalho Chehab <mchehab@infradead.org>
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

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

- Updated firmware names
- kfree (NULL) is valid.
- assert_spin_locked() is the new way
- small fixes to make in sync with kernel

- 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)

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?
