2008-04-24V4L/DVB (7711): pvrusb2: Fix race on module unloadMike Isely
The pvrusb2 driver - for basically forever - was not enforcing a proper module tear-down. Kernel threads are used inside the driver and all must be gone before the module can be safely removed. This changeset reimplements a chunk of pvrusb2-context.c to enforce this correctly. Unfortunately this is not a simple fix. The new implementation also cuts back on kernel thread usage; instead of there being 1 control thread per instance now it's just 1 control thread shared by all instances. (By dropping to a single thread then the module exit function can block on its shutdown and the thread itself can monitor and cleanly shut down all of the other instances first.)

2008-04-24V4L/DVB (7692): pvrusb2-dvb: Further clean up dvb init/tear-downMike Isely
Move pvr2_dvb_adapter usage out of the pvrusb2 driver core - it's really private to the pvrusb2-dvb module and nothing outside of the dvb implementation should care about it. Creation / destruction of the pvr2_dvb_adapter instance is now contained entirely within pvrusb2-dvb.c.

2008-04-24V4L/DVB (7689): pvrusb2-dvb: Rework module tear-downMike Isely
Rather than making an explicit call to tear down the pvrusb2-dvb module, use the callback in the pvr2_channel structure. This has the advantage that now tear-down only happens when it makes sense. The previous implementation had scenarios where it was possible for the tear-down call to happen without a prior initialization.

2008-04-24V4L/DVB (7679): pvrusb2: add DVB API frameworkMichael Krufky
Add basic framework for the DVB API. This is enough to control the tuner & demod of the digital frontend, but the stream & buffer handling is still missing. Additional note from Mike Isely <isely@pobox.com> - also, since these changes are still very experimental arrange for DVB changes to be compiled in via new CONFIG_VIDEO_PVRUSB2_DVB option, for now.

2008-01-25V4L/DVB (6692): pvrusb2: Centralize device specific attributes into a single ↵Mike Isely
place The pvrusb2 driver currently supports two variants of the Hauppauge PVR USB2. However there are other hardware types potentially supportable, but the driver at the moment is not structured to make it easy to describe these minor variations. This changeset is the first set of changes to make such additional device support possible. Device attributes are held in several tables all contained within pvrusb2-devattr.c; all other device-specific driver behavior now derives from these tables.

2007-11-04V4L/DVB (6548): pvrusb2: Fix oops on module removalMike Isely
The pvrusb2 driver is tearing down its sysfs related pieces in the incorrect order. This leaves dangling pointers which causes the kernel device core to oops. The problem has been present virtually forever but became malignant with the changeover to the way of handling /sys/class. Fix is just to make sure we don't tear down the class structure until AFTER the driver instances are deregistered.

standard things It's useful to see specific details for how the pvrusb2 driver is figuring out things related to the video standard, independent of other initialization activities. So let's set up a separate debug mask bit for this and turn it on. 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.
