2007-02-21V4L/DVB (5086): Pvrusb2: Fix missing break statement on VIDIOC_S_TUNERMike Isely
The lack of a break statement in the handling of VIDIOC_S_TUNER caused errors to result. Fixed. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-21V4L/DVB (5081): Pvrusb2: VIDIOC_G_TUNER cleanupMike Isely
Clean up use of VIDIOC_G_TUNER; we now correctly gather info from all the I2C client modules. Also abide by V4L2_TUNER_CAP_LOW appropriately. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-02-21V4L/DVB (5059): Pvrusb2: Be smarter about mode restorationMike Isely
Switch back to the previous input selection when the radio device is closed - but only do that if the current input selection is still the radio (i.e. it appears that it hasn't been messed with).

2007-02-21V4L/DVB (5058): Pvrusb2: bug fix involving switch into radio modeMike Isely
When the input is switched by opening /dev/radioX, we must also commit that change into the driver core. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-21V4L/DVB (5057): Pvrusb2: Stream configuration cleanupsMike Isely
Clean up and tighten logic involving stream configuration. This mainly involves changes to pvrusb2-v4l2.c, where we better clarify how we use the stream configuration enum and implement a cleaner means to control streaming for a given device node.

2007-02-21V4L/DVB (5052): Pvrusb2: Remove stream claiming hack from /dev/radioMike Isely
Trying to temporarily check that the stream is not claimed during open of the radio device is at best a race condition. What's to stop another app from claiming the stream anyway the instant after the check is done? The implementation for this was dicey anyway. So it's removed. The only "price" for this is that if /dev/radioX is opened while streaming video, then the video stream is just going to switch to radio mode anyway. If a user does this, he gets what he expects...

2007-02-21V4L/DVB (5045): Pvrusb2: Fix heap corruption introduced by radio modsMike Isely
We can't allocate v4l device structures in a block, since the v4l core governs when each device actually gets freed. This bug was introduced as part of the core radio implementation. Fix it. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-21V4L/DVB (5044): Pvrusb2: Allow overriding vbi and radio device minor numbersMike Isely
Support specification of vbi and radio device minor numbers in a manner similar to the video device minor number. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-21V4L/DVB (5041): Pvrusb2: Use separate enumeration for get/store of minor numberMike Isely
Use separate enum for get/store of minor number; we want pvr2_config to go away eventually and since it really means something different, don't use it here Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-02-21V4L/DVB (5039): Pvrusb2: Implement /dev/radioXPantelis Koukousoulas
The "main" V4L2 interface patch. This is yet very incomplete, incorrect and probably inappropriate for inclusion as-is, but at least with this I 'm able to tune and play radio through a V4L2 program (pvr-radio.c, a "thumb" version of ivtv-radio.c with just the essentials). Therefore, it kinda gives an idea of what is needed to support this, hm, interface (partly used also by e.g., kradio). Please point out any mistakes on this code. I 'm sure I 'm messing up some struct initialization somewhere but currently I 'm too lazy to actually think this through until I complete the functionality (e.g., handle the VIDIOC_S_STD, ENUMINPUT, etc ioctls appropriately).

2007-02-21V4L/DVB (5037): Pvrusb2: Implement multiple minor device number handlingPantelis Koukousoulas
This is the first patch in preparation of the V4L2/IVTV radio interface. It does away with the assumption of only one minor per device. It also adds a file to show the radio minor as well. This can be useful for a program like pvr-radio.c (when it grows up), since this way it can search for the minor of the /dev/radioX device it opened and use the video minor of the same driver instance to get to the actual stream. The implementation looks kinda ugly. Feel free to improve (that is the reason behind separate patches anyway).

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.

2006-10-03V4L/DVB (4663): Pvrusb2: Get rid of private global context array brain damageMike Isely
A previous attempt to deal with the upcoming loss of video_set_drvdata() and video_get_drvdata() resulted in logic which causes a circular locking dependency - also known as a deadlock. This changeset attacks the problem in a different manner, using a technique that no longer requires the problematic mutex (or that private global array either).

2006-09-26V4L/DVB (4375): Eliminate hardcoded limits in VIDIOC_[S|TRY]_FMT for pvrusb2Mike Isely
The pvrusb2 implementation for VIDIOC_[S|TRY]_FMT was hardcoding limits on the range for allowed resolution, but it would be much better if we instead just queried the internal control for these values. This then opens the door for the driver to adjust these limits based on the detected hardware. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

Implement V4L2 driver for the Hauppauge PVR USB2 TV tuner. The Hauppauge PVR USB2 is a USB connected TV tuner with an embedded cx23416 hardware MPEG2 encoder. There are two major variants of this device; this driver handles both. Any V4L2 application which understands MPEG2 video stream data should be able to work with this device.
