2007-02-12[PATCH] mark struct file_operations const 4Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2007-01-15V4L/DVB (5020): Fix: disable interrupts while at KM_BOUNCE_READMauro Carvalho Chehab
vivi.c uses the KM_BOUNCE_READ with local interrupts enabled. This means that if a disk interrupt occurs while vivi.c is using this fixmap slot, the vivi.c driver will, upon return from that interrupt, find that the fixmap slot now points at a different physical page. The net result will probably be rare corruption of disk file contents, because viv.c will now be altering the page which the disk code was recently using. Thanks to Andrew Morton for pointing this.

2006-12-10V4L/DVB (4861): Remove the need of a STD array for drivers using video_ioctl2Mauro Carvalho Chehab
video_ioctl2 will auto-generate standard entries at ENUM_FMT. Also, now, a driver may return a subset of the video array at the return, to be stored as the current_norm. For example, a driver may ask for V4L2_STD_PAL. At return, driver may change it to V4L2_STD_PAL_B. This way, a futher call to G_STD will return the exact detected video std.

2006-12-07[PATCH] Add include/linux/freezer.h and move definitions from sched.hNigel Cunningham
Move process freezing functions from include/linux/sched.h to freezer.h, so that modifications to the freezer or the kernel configuration don't require recompiling just about everything.

2006-09-26V4L/DVB (4627): Vivi crashes with mplayerSascha Hauer
The vivi.current_norm field is not initialized in vivi.c, so a VIDIOC_G_STD ioctl without a prior call to VIDIOC_S_STD gives unpredictable results. mplayer does exactly this. Signed-off-by Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-09-26V4L/DVB (4510): Fix signedness error in drivers/media/video/vivi.cEric Sesterhenn
when checking the -Wextra signedness warnings issued by gcc 4.1 I came across this one: drivers/media/video/vivi.c:1001: warning: comparison of unsigned expression < 0 is always false Since videobuf_reqbufs() returns negative values on errors the current code does no real error checking since gcc removes the comparison. This patch fixes this issue by making ret a normal, signed integer. Signed-off-by: Eric Sesterhenn <snakebyte@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2006-05-12V4L/DVB (3774): Create V4L1 config optionsMauro Carvalho Chehab
V4L1 API is depreciated and should be removed soon from kernel. This patch adds two new options, one to disable V4L1 drivers, and another to disable V4L1 compat module. This way, it would be easy to check what still depends on V4L1 stuff, allowing also to test if app works fine with V4L2 only support. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2006-03-24V4L/DVB (3518): Creates a virtual video device driverMauro Carvalho Chehab
The Virtual Video Device Driver (aka vivi) is a device that can be used to: 1) test core v4l functionalities; 2) be a prototype for newer development. Vivi were developed using the best practices for v4l driver. When loaded, it provides a video device that generates a standard color bar, with a timestamp placed at top left corner.
