This patch contains the following cleanups and fixes: - "debug" is definitely not a good name for a global variable, renamed it to "au0828_debug" this fixes a compile error with some kernel configurations - since the module parameter is int the variable shouldn't be unsigned - remove the {usb,bridge,i2c}_debug module parameters since they are already covered by the "debug" module parameter - remove the unused au0828_bcount - make the needlessly global i2c_scan static - make the needlessly global dvb_register() static Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-26V4L/DVB (7748): tuner-core: some adjustments at tuner logs, if debug enabledMauro Carvalho Chehab1-46/+46
set_addr log were almost useless: discarded SET_TYPE_ADDR commands weren't reported. This patch changed set_addr printk to print a message only if set_addr is wrong. It also fix printk at set_type, since, if an attach were failing, nothing were reported. With the current code, working or not, a call to set_addr will produce a debug printk. also, set_type() were producing a false error message on tuner_xc2028, since it were requesting for setting a frequency on a place where firmware name weren't set yet.

Frank Bennett reported that ivtv was causing skype to crash. With help from one of their developers he showed it was a kernel problem. VIDIOCGCAP copies a name into a fixed length buffer - ivtv uses names that are too long and does not truncate them so corrupts a few bytes of the app data area. Possibly the names also want trimming but for now this should fix the corruption case.

Apparently the kernel developers no longer consider it proper etiquette to use __FUNCTION__; everyone must instead use __func__ (even though it breaks with older compilers). And worse still, actual effort is being expended to sweep this change throughout the kernel source tree. Don't these people have better things to do? So... Completely clean out all use of __FUNCTION__ from the pvrusb2 driver (it was just in the sysfs interface). I'm not going to use __func__ either. So there.

2008-04-24V4L/DVB (7714): pvrusb2: Fix hang on module removalMike Isely1-1/+18
The pvrusb2 driver was getting had by this scenario: 1. Task A calls kthread_stop() for task B. 2. Before exiting, then Task B calls kthread_stop() for task C. The problem is, kthread_stop() wants to allocate an internal resource to itself (i.e. acquire a lock), which won't be released until kthread_stop() returns. But kthread_stop() won't return until task B is dead. But task B won't die until it finishes its call to kthread_stop() for task C, and that will block waiting on the resource already allocated inside task A. Deadlock. With the pvrusb2 driver, task A is the caller to pvr_exit(), task B is the control thread run inside of pvrusb2-context.c, and task C is any worker thread run inside of pvrusb2-hdw.c. This problem got introduced by the previous threading setup change, which was itself an attempt to fix a module tear-down race (which it actually did fix). The lesson here is that a task being waited on as part of a kthread_stop() simply cannot be allow to also issue a kthread_stop() - or we make sure not to issue the enclosing kthread_stop() until we know that the inner kthread_stop() has completed first. The solution for the pvrusb2 driver is some hackish code which changes the main control thread tear down into a two step process. This then makes it possible to delay issuing the kthread_stop() on the control thread until after we know that everything has been torn down first. (And yes, we really need that kthread_stop() because it's the only way to safely guarantee that a module-referencing kernel thread has safely returned back out of the module before we finally remove the module.)

2008-04-24V4L/DVB (7712): pvrusb2: Close connect/disconnect raceMike Isely1-1/+10
If a disconnect happens before initialization is completed, the pvrusb2 driver can accidentally touch dangling pointers. The whole initialization function must be protected by the big_lock, and once inside that lock, the initialization function should abort if it is discovered that a disconnect has already taken place.

2008-04-24V4L/DVB (7711): pvrusb2: Fix race on module unloadMike Isely3-51/+174
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.)

On top of that implement various bits to ensure that the encoder has been run once before digital streaming for OnAir devices. This is done via several core state machine tweaks.

Numerous places in the driver need to issue simple commands to the FX2 microcontroller (e.g. only 1 or 2 bytes, no reply needed). Previously each place that did this, had to take lock, set up a central buffer, and call the function to perform the handshake. This change puts these steps into a single spot. This also has the effect of removing the need to mess with the control lock from numerous places in the code.

2008-04-24V4L/DVB (7699): pvrusb2: Implement statistics for USB I/O performance / trackingMike Isely4-0/+84
Implement a mechanism in the pvrusb2 driver for gathering statistics on the stream buffering, including bytes transferred, buffers handled, buffers in flight, etc. This is useful for debugging certain classes of streaming issues and for determining if the buffer pool size is generally correct for the driver.
