* V4L/DVB (5147): Make vivi driver to use vmalloced pointersMauro Carvalho Chehab2007-02-21
| | | | | | | | | | | | | | | | | | | | | Before this patch, vivi were simulating a scatter gather DMA transfer. While this is academic, showing how stuff really works on a real PCI device, this means a non-optimized code. There are only two memory models that vivi implements: 1) kernel alloced memory. This is also used by read() method. On this case, a vmalloc32 buffer is allocated at kernel; 2) userspace allocated memory. This is used by most userspace apps. video-buf will store this pointer. a simple copy_to_user is enough to transfer data. The third memory model scenario supported by video-buf is overlay mode. This model is not implemented on vivi and unlikely to be implemented on newer drivers, since now, most userspace apps do some post-processing (like de-interlacing). After this patch, some cleanups may be done at video-buf.c to avoid allocating pages, when the driver doesn't need a PCI buffer. This is the case of vivi and usb drivers.

* V4L/DVB (5146): Make VIDIOC_INT_[SG]_REGISTER ioctls no longer internal onlyTrent Piepho2007-02-21
| | | | | | | | | | | | | | | | | | | | | The direct register access ioctls were defined as kernel internal only, but they are very useful for debugging hardware from userspace and are used as such. Officially export them. VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER Definition of ioctl and struct v4l2_register is moved from v4l2-common.h to videodev2.h. Types used in struct v4l2_register are changed to the userspace exportable versions (u32 -> __u32, etc). Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move the check into the video_ioctl2() dispatcher so it doesn't need to be duplicated in each driver's call-back function. CAP_SYS_ADMIN check is added to pvrusb2 (which doesn't use video_ioctl2). Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

* V4L/DVB (5102): make videodev to auto-generate standardsMauro Carvalho Chehab2007-02-21
| | | | | | | | | | | | v4l2_tvnorm were meant to describe video standards and its names to V4L2 API. However, this were doing by some static structures at the driver. This patch changes the internals in a way that, at the driver, only a v4l2_tvnorm (a 64 bit integer) should be filled, with all supported tvnorms. videodev will dynamically generate the proper API array based on supported standards.

* V4L/DVB (5097): Convert cx8800 driver to video_ioctl2 handlerMauro Carvalho Chehab2007-02-21
| | | | | | | | | | video_ioctl2 handler provides V4L2 API parsing. Using it makes the driver simpler, and isolates API parsing. This allows future reusage of driver controls using other ways, like sysfs and/or procfs and increases isolation of driver-specific handling from the generic common ioctl processing.

* V4L/DVB (5095): Pvrusb2: Allow VIDIOC_S_FMT with -1 for resolution valuesPantelis Koukousoulas2007-02-21
| | | | | | | | | | | | | | | | | | | | | | With the previous patch, mplayer started but was polling the video device forever without any video actually coming out. Further analysis showed that it does a VIDIOC_S_FMT with width and height set to -1 (!!!). The code handling this only cares that both are lower than the minimum range allowed so it ends up setting the size to 19x17 (!!) This pretty much breaks the encoder here. Even if this breakage is yet another (TM) result of my setup, setting the size to 19x17 by default would surprise most users IMHO. So, special case for -1 and interpret this to be a request for the default size, please. Users can then set their favorite size both through mplayer and through sysfs. With this patch, mplayer finally works in pvr:// mode (not that we really gain anything over operating it through sysfs with lirc, sometime I might actually get off my lazy a** and contribute this setup too) Signed-off-by: Pantelis Koukousoulas <pakt223@freemail.gr> Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

| | | | | | | | | | | | | Audio mode changes are not private to the audio chip - other I2C modules need to see this as well. And since the command in question is VIDIOC_S_TUNER which is a standard v4l2 command, we really should be broadcasting it out. This change sets up a broadcast pathway for VIDIOC_S_TUNER and also eliminates the now redundant code from the audio chip handler.

* V4L/DVB (5077): Bttv cropping supportMichael Schimek2007-02-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | Adds the missing VIDIOC_CROPCAP, G_CROP and S_CROP ioctls, permitting applications to capture or overlay a subsection of the picture or to extend the capture window beyond active video, into the VBI area and the horizontal blanking. VBI capturing can start and end on any line, including the picture area, and apps can capture different lines of each field and single fields. For compatibility with existing applications, the open() function resets the cropping and VBI capturing parameters and a VIDIOC_S_CROP call is necessary to actually enable cropping. Regrettably in PAL-M, PAL-N, PAL-Nc and NTSC-JP mode the maximum image width will increase from 640 and 768 to 747 and 923 pixels respectively. Like the VBI changes however, this should only affect applications which depend on former driver limitations, such as never getting more than 640 pixels regardless of the requested width. Also, new freedoms require additional checks for conflicts and some applications may not expect an EBUSY error from the VIDIOC_QBUF and VIDIOCMCAPTURE ioctls. These errors should be rare though. So far, the patch has been tested on a UP machine with a bt878 in PAL- BGHI and NTSC-M mode using xawtv, tvtime, mplayer/mencoder, zapping/ libzvbi and these tools: http://zapping.sf.net/bttv-crop-test.tar.bz2 I'd be grateful about comments or bug reports.
