2008-04-09pvrusb2: Clean out all use of __FUNCTION__Mike Isely
From: Mike Isely <isely@pobox.com> 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. Signed-off-by: Mike Isely <isely@pobox.com>
2008-04-09pvrusb2: Fix hang on module removalMike Isely
From: Mike Isely <isely@pobox.com> 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.)

2008-04-06pvrusb2: Close connect/disconnect raceMike Isely
From: Mike Isely <isely@pobox.com> 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.

2008-04-06pvrusb2: Fix race on module unloadMike Isely
From: Mike Isely <isely@pobox.com> 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.)

2008-04-05pvrusb2: Implement critical digital streaming quirk for onair devicesMike Isely
From: Mike Isely <isely@pobox.com> Implement timed measurement of encoder operation for the first time it is run. This allows the driver to note when the encoder has been run successfully for at least 1/4 second. 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.
