-
- This single function is key to pretty much everything. The pvrusb2
- device can logically be viewed as a series of subsystems which can be
- stopped / started or unconfigured / configured. To get things streaming,
- one must configure everything and start everything, but there may be
- various reasons over time to deconfigure something or stop something.
- This function handles all of this activity. Everything EVERYWHERE that
- must affect a subsystem eventually comes here to do the work.
-
- The current state of all subsystems is represented by a single bit mask,
- known as subsys_enabled_mask. The bit positions are defined by the
- PVR2_SUBSYS_xxxx macros, with one subsystem per bit position. At any
- time the set of configured or active subsystems can be queried just by
- looking at that mask. To change bits in that mask, this function here
- must be called. The "msk" argument indicates which bit positions to
- change, and the "val" argument defines the new values for the positions
- defined by "msk".
-
- There is a priority ordering of starting / stopping things, and for
- multiple requested changes, this function implements that ordering.
- (Thus we will act on a request to load encoder firmware before we
- configure the encoder.) In addition to priority ordering, there is a
- recovery strategy implemented here. If a particular step fails and we
- detect that failure, this function will clear the affected subsystem bits
- and restart. Thus we have a means for recovering from a dead encoder:
- Clear all bits that correspond to subsystems that we need to restart /
- reconfigure and start over.
