2007-10-22bttv: Update initial image size when set via V4L1 VIDIOCMCAPTURETrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> The V4L1 spec says that the image size should be with with VIDIOCSWIN before requesting buffers with VIDIOCGMBUF and capturing into them with VIDIOCMCAPTURE. But it seems that many apps don't do this. They set the size using the fields in the VIDIOCMCAPTURE ioctl. The driver doesn't know what size to capture until it actually starts to capture. In particular, it doesn't know what size to capture until it has already mmap the captured buffers. Which is quite stupid. Why V4L1 has size and format fields for VIDIOCMCAPTURE I have no idea. Many drivers don't support this, including those using v4l1-compat. The bttv does, which is probably the only reason such broken software is so prevalent. But, the driver doesn't adjust its idea of what size is being captured when it is set this way. If you try to query the driver's current setting with v4l2-ctl, it won't be correct.

2007-10-22bttv: SPICT ioctl doesn't work with vlcTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> The bttv driver instists that the depth specified in the call to VIDIOCSPICT match the pixel format specified in the same call. vlc doesn't set the depth field, which makes the SPICT ioctl always fail. The V4L1 standard is not clear on how most operation are supposed to work, and this is no exception. The depth field would appear to be entirely redundant, as the pixel format specifies a specific depth. It could be that this field was only meant for output from the *G*PICT ioctl and should be ignored in *S*PICT. This is in fact what the v4l1-compat wrapper does.

2007-10-18Adds the capability of configuring tea5767 supportMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> tea5767 has several possible configurations. Before the patch, the driver were assuming the more common configuration. However, some newer cards, like MSI @nyware Master requires other configurations, like de-activating a gpio port and changing chip Xtal. This patch adds the capability of altering device configuration at runtime. This may also be used later to activate some features like auto-mute when signal is weak.

2007-10-18Replace TDA9887_SET_CONFIG by TUNER_SET_CONFIGMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Currently, the only tuner-specific device that allows special configurations is tda9887. However, tea5767 also may require some special configurations (for example, to specify a different Xtal freq). This patch replaces TDA9887_SET_CONFIG by a more generic internal ioctl (TUNER_SET_CONFIG). The newer one allows specifying what tuner is appliable to a configuration set, and allows an arbitrary configuration struct. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

From: Mauro Carvalho Chehab <mchehab@infradead.org> Original Description: Author: Kay Sievers <kay.sievers@vrfy.org> Date: Tue Aug 14 15:15:12 2007 +0200 Driver core: change add_uevent_var to use a struct This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

2007-10-14ivtvfb: YUV output size fix when ivtvfb is not loaded.Hans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> If the ivtvfb module isn't loaded, the valid YUV output area should be set to full-screen.

2007-10-14ivtvfb: YUV handling of an image which is not visible in the display area.Hans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> When the ivtvfb module is loaded, the YUV output is relative to the framebuffer output. When a virtual screen size is used, the output area for the YUV may actually be off screen. To prevent the hardware from crashing, the current driver will ignore an off-screen position and leave the output visible at the last on-screen position. This may not be desirable, so this patch will switch off the YUV output should the image move off-screen, and re-enable it should the image move on-screen again.

2007-10-12ivtvfb: screen mode change sometimes goes wrong.Hans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> This patch partially reverts a previous change that caused the CX2341X_OSD_SET_PIXEL_FORMAT firmware calls to be skipped when the pixel format of the framebuffer wasn't altered by FBIOPUT_VSCREENINFO. Unfortunately, another firmware call on the PVR350 sometimes scrambles the display when trying to adjust the framebuffer settings. This patch re-enables the CX2341X_OSD_SET_PIXEL_FORMAT calls to try and prevent this from occurring.
