The VID_TYPE defines are V4L1 specific, so copy them back to videodev.h.
In videodev2.h ensure that they are not used in the kernel (you need
to include videodev.h instead) and mark them are deprecated.

struct video_device used to define a .hardware field. While
initialized on severl drivers, this field is never used inside V4L.
However, drivers using it need to include the old V4L1 header.
This seems to cause compilation troubles with some random configs.
Better just to remove it from all drivers.

V4L1 support should be disabled when no CONFIG_VIDEO_V4L1_COMPAT is defined,
to allow checking for broken V4L2 ports. This is very important during the
migration phase for V4L2 API.
However, userspace apps should be capable of using both APIs, since they need
to test at runtime, via VIDIOCGCAP ioctl, if V4L1 is supported. So, when
__KERNEL__ is not defined, those ioctls and corresponding structs should be
visible.
This patch also removes the obsolete defines HAVE_V4L1 and HAVE_V4L2, that
where causing some confusion, and were replaced by CONFIG_VIDEO_V4L1_COMPAT
and CONFIG_VIDEO_V4L2.

Removed usage of HAVE_V4L1
Including videodev.h will just include videodev2.h if V4L1 is not supported
V4L1 code at core drivers will honor CONFIG_V4L1_COMPAT stuff

videodev2.h
The videodev.h and videodev2.h describe the public API for V4L and V4L2.
It shouldn't have there any kernel-specific stuff. Those were moved to
v4l2-dev.h.
This patch removes some uneeded headers and include v4l2-common.h on all
V4L driver. This header includes device implementation of V4L2 API provided
on v4l2-dev.h as well as V4L2 internal ioctls that provides connections
between master driver and its i2c devices.

Videodev now is capable of better handling V4L2 api, by
processing V4L2 ioctls and using callbacks to the driver.
The drivers should be migrated to the newer way and the older
one will be obsoleted soon.

This single patch contains some updates and cleanups for
the W996[87]CF driver and a new experimental V4L2 driver
for SONiX SN9C10[12] PC Camera Controllers connected to various
image sensors. I have not divided the patch in two logical
sub-patches becouse of two independent changes in one common
file, KConfigure.
More informations about the SN9C10[12] can be found below in the
documentation. The driver is marked as "EXPERIMENTAL", meaning
that there are no known bugs, but further testing is necessary
before considering it stable. This the first driver using the new
SBGGR8 video format, which has been recently added to the mainline
kernel, so there are no available user application at the moment:
this is one more reason why it should be in the kernel now.
Changes in W996[87]CF:
- remove w9968cf_externaldef.h now that ovcamchip.h is in the kernel;
- mark user pointers with __user in a cleaner way to avoid sparse
warnings;
- use appropriate exclusive wait macro during open();
- replace info(), err(), warn() with dev_info(), dev_err(), dev_warn(),
pr_debug(), pr_info();
- replace usb_unlink_urb() + wait_for_completion() with usb_kill_urb();
- fix memory offsets for buffers in the chip to be used with generic
image sensors;
- 'vppmod_load', 'debug', 'specific_debug' and 'simcams' module
parameters are now writeable by default;
- fix possible race conditions between disconnect() and open();
- add automatic 'ovcamchip' module loading option with 'ovmod_load'
module parameter;
- get rid of deprecated intermodule communication routines and use the
correct module registration/unregistration approach;
- remove period at the end of kernel messages;
- fix several typos;
- use MODULE_VERSION() macro;
- other small internal cleanups;
- documentation updates.

From: Gerd Knorr <kraxel@bytesex.org>
Minor tweak in the v4l1 compatibility layer: Make sure that capture actually
is active before going to wait for a frame so we don't block forever.
|
|
From: Gerd Knorr <kraxel@bytesex.org>
This patch is a v4l2 update. Changes:
* added new ioctls (VIDIOC_G_PRIORITY, VIDIOC_S_PRIORITY) to give v4l apps
priorities for tuning and other controls. Main purpose is that backgrounds
applictions like nxtvepg which are fishing informations from /dev/vbi
(teletext, epg, ...) can run at lower priority than interactive tv apps and
thus the user isn't annonyed with unexpected channel switches.
* add a set of helper functions to handle priorities to the v4l2-common
module.
* minor fixes in the v4l1-compat module.
* minor header file fixes.

This patch drops procfs code from videodev.c and adds sysfs support
instead. It adds a new class where all v4l devices are listed. It
also provides some new helper functions for v4l drivers.
|
|
Now that devfs_handle_t is gone from all structs there is no
reason to include it in headers.
Fix the fallout by including previously implicit headers and fixing
the drivers that didn't include devfs_fs_kernel.h explicitly.

This adds the v4l2 API to the linux kernel.
The first, original video4linux API has a number of design bugs. They
are fixed in this new API revision. It already exists for quite some
time. Last weeks it got a number of cleanups based on the experiences
of the last years (drop stuff nobody uses, fix some inconsistencies).
We consider it being in a pretty good shape now and like to see it in
2.6.
This patch is basically the header file with all the structs and ioctls
in there. A small module with some helper functions for v4l2 drivers is
included too. Related updates (bttv, ...) will follow as separate
patches.

Originally from Gerd...
I've just noticed that a hole left in the recent changes which should
allow the usb v4l drivers to unregister with open file handles. The
drivers itself handle it just fine, but video_generic_ioctl() will barf
when called on unregistered devices. Oops.
One way to fix this is to expect drivers call the helper function and
pass a pointer for the function doing the actual work, i.e. handle it
this way:
driver_ioctl(inode,file,cmd,userptr)
-> video_usercopy(inode,file,cmd,userptr,func)
copy_from_user(...)
-> func(inode,file,cmd,kernelptr);
copy_to_user(...)
Patch against 2.5.7-pre2 below. It updates videodev.[ch] and adapts
usbvideo.c to show how the driver changes will look like.
Note that this change makes the usercopy helper function a very generic
one, it probably could be used for other drivers to (as long as the API
has sane magic numbers based on _IO*(...) defines) as there is no
video4linux-related stuff in there any more. So we might think of
renaming it an moving it to some more central place (fs/ioctl.c maybe).
|
|
This patch is a redesign for videodev.[ch]. Changes:
- drop the function pointers (read/write/mmap/poll/...) from struct
video_device, use struct file_operations directly instead.
Dispatching to different drivers by minor number is done the same way
soundcore.o handles this: swap file->f_fops at open() time.
- also drop the now obsolete video_red/write/mmap/poll/... functions
from videodev.c
- Stop using the BKL, use a mutex to protect open,register+unregister
calls against races.
- provide a video_generic_ioctl() function which can (and should) be
used by v4l drivers to handle copying from and to userspace.
- provide video_exclusive_open/release functions which can be used by
v4l drivers to make sure only one process at a time opens the
device. They can be hooked directly into struct file_operations if
some driver has nothing to initialize at open time (which is true
for many drivers in drivers/media/radio/).
The move from function pointers in struct video_device to struct
file_operations does break all existing v4l drivers. Thus I have a
large number of patches for the drivers in the kernel tree. Most of it
is just the adoption to the videodev.[ch] changes, but I've also fixed a
small bug there and there while walking througth the source files.
