2009-03-11libv4l: Don't report DQBUF errors when errno is EAGAINhans@rhel5-devel.localdomain
From: Hans de Goede <hdegoede@redhat.com> Don't report DQBUF errors when errno is EAGAIN, this fixes flooding the screen with errors when applications use non blocking mode Priority: normal Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2009-03-11libv4l: dont try to allocate large buffers on the stackhans@rhel5-devel.localdomain
From: Hans de Goede <hdegoede@redhat.com> When conversion requires multiple passes don't alloc the needed temporary buffer on the stack, as some apps (ekiga) use so much stack themselves this causes us to run out of stack space Priority: normal Signed-off-by: Hans de Goede <hdegoede@redhat.com>

2009-03-11libv4l: Make S_FMT handling more robusthans@rhel5-devel.localdomain
From: Hans de Goede <hdegoede@redhat.com> Some drivers (pwc) do not properly reflect what one really gets after a s_fmt in their try_fmt answer. So update dest format (which we report as result from s_fmt / g_fmt to the app) with all info from the src format not changed by conversion.

2009-03-11libv4l: Add software cropping from CIF to VGA modes (fix skype)hans@rhel5-devel.localdomain
From: Hans de Goede <hdegoede@redhat.com> * Add support for software cropping from 352x288 -> 320x240 / 176x144 -> 160x120, so that apps which will only work with vga resolutions like 320x240 (Skype!) will work with cams/drivers which do not support cropping CIF resolutions to VGA resolutions in hardware. This makes all 2.6.27 gspca supported cams, except for the pac7302 which only does 640x480 (and skype wants 320x240), work with skype * The v4lconvert_convert function was becoming a bit of a mess, so split the functionailiy into seperate v4lconvert_convert_pixfmt, v4lconvert_rotate and v4lconvert_crop functions, and make v4lconvert_convert a frontend to these Priority: normal Signed-off-by: Hans de Goede <hdegoede@redhat.com>

2009-03-05cx88: Prevent general protection fault on rmmodMauro Carvalho Chehab
From: Jean Delvare <khali@linux-fr.org> When unloading the cx8800 driver I sometimes get a general protection fault. Analysis revealed a race in cx88_ir_stop(). It can be solved by using a delayed work instead of a timer for infrared input polling. This fixes kernel.org bug #12802.

2009-03-10zoran: replace functions names in strings with __func__Trent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> It reduces the size of the driver over all, and the function names in strings need to be manually kept up to date while __func__ doesn't. Priority: normal Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
2009-03-10zoran: Pass zoran_fh pointers instead of file pointersTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Many functions had a struct file pointer argument, but all they wants is the struct zoran_fh pointer from the file's private data. Since every caller of those functions already has the zoran_fh, just pass the that instead. This saves a dereference in each function change. While I'm at it, change the code formatting of affected functions to be kernel standard style. Priority: normal Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
2009-03-10zoran: Don't frighten users with failed buffer allocationTrent Piepho
From: Jean Delvare <khali@linux-fr.org> kmalloc() can fail for large video buffers. By default the kernel complains loudly about allocation failures, but we don't want to frighten the user, so ask kmalloc() to keep quiet on such failures.

2009-03-10zoran: Drop the lock_norm module parameterTrent Piepho
From: Jean Delvare <khali@linux-fr.org> The lock_norm module parameter doesn't look terribly useful. If you don't want to change the norm, just don't change it. As a matter of fact, no other v4l driver has such a parameter.

2009-03-10zoran: Unify buffer descriptorsTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> The zoran driver had two kinds of buffer descriptors, one for jpg buffers and one for raw buffers. They were mostly the same with only a couple different fields. A file handle had two sets of descriptors even though only one could be in use at once. I've combined the two kinds into a single buffer descriptor that has the different parts in a union. Each file handle (struct zoran_fh) now only has one set of buffers. The device itself (struct zoran) still has two since it can have both raw and jpg buffers in use at the same time. Along the way, I re-wrapped many lines that were ugly. Some code which was duplicated for both raw and jpg buffers is now merged. The code to setup buffers in zoran_open_init_session() can be merged, as can the code to delete the buffers in zoran_close_end_session(). Lots of code in zoran_vm_close() and zoran_mmap() is merged as well. Since there is now only one set of buffer size & count fields, it's important they get set correctly when changing modes. So I created helper functions to change fh->map_mode which also set the buffer size & count to the proper values. jpg_sync() should only be called in jpg mode, it used to be able to tell the difference between jpg mode active and raw mode, but now there is only one active field. In zoran_streamoff() the spin lock is held for the entire sequence of operations to disable streaming. Priority: normal Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>

2009-03-08v4l2-ioctl: fix partial-copy code.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The code to optimize the usercopy only checked the ioctl NR field. However, this code is also called for non-V4L2 ioctls (either private or ioctls from linux/dvb/audio.h and linux/dvb/video.h for decoder drivers like ivtv). If such an ioctl has the same NR as a V4L2 ioctl, then disaster strikes. Modified the code to check on the full command ID.
