1345 | This single function is key to pretty much everything. The pvrusb2 | |
1346 | device can logically be viewed as a series of subsystems which can be | |
1347 | stopped / started or unconfigured / configured. To get things streaming, | |
1348 | one must configure everything and start everything, but there may be | |
1349 | various reasons over time to deconfigure something or stop something. | |
1350 | This function handles all of this activity. Everything EVERYWHERE that | |
1351 | must affect a subsystem eventually comes here to do the work. | |
1352 | ||
1353 | The current state of all subsystems is represented by a single bit mask, | |
1354 | known as subsys_enabled_mask. The bit positions are defined by the | |
1355 | PVR2_SUBSYS_xxxx macros, with one subsystem per bit position. At any | |
1356 | time the set of configured or active subsystems can be queried just by | |
1357 | looking at that mask. To change bits in that mask, this function here | |
1358 | must be called. The "msk" argument indicates which bit positions to | |
1359 | change, and the "val" argument defines the new values for the positions | |
1360 | defined by "msk". | |
1361 | ||
1362 | There is a priority ordering of starting / stopping things, and for | |
1363 | multiple requested changes, this function implements that ordering. | |
1364 | (Thus we will act on a request to load encoder firmware before we | |
1365 | configure the encoder.) In addition to priority ordering, there is a | |
1366 | recovery strategy implemented here. If a particular step fails and we | |
1367 | detect that failure, this function will clear the affected subsystem bits | |
1368 | and restart. Thus we have a means for recovering from a dead encoder: | |
1369 | Clear all bits that correspond to subsystems that we need to restart / | |
1370 | reconfigure and start over. | |
