-
- The encoder seems to speak entirely using blocks 32 bit words.
- In ivtv driver terms, this is a mailbox which we populate with
- data and watch what the hardware does with it. The first word
- is a set of flags used to control the transaction, the second
- word is the command to execute, the third byte is zero (ivtv
- driver suggests that this is some kind of return value), and
- the fourth byte is a specified timeout (windows driver always
- uses 0x00060000 except for one case when it is zero). All
- successive words are the argument words for the command.
-
- First, write out the entire set of words, with the first word
- being zero.
-
- Next, write out just the first word again, but set it to
- IVTV_MBOX_DRIVER_DONE | IVTV_DRIVER_BUSY this time (which
- probably means "go").
-
- Next, read back 16 words as status. Check the first word,
- which should have IVTV_MBOX_FIRMWARE_DONE set. If however
- that bit is not set, then the command isn't done so repeat the
- read.
-
- Next, read back 32 words and compare with the original
- arugments. Hopefully they will match.
-
- Finally, write out just the first word again, but set it to
- 0x0 this time (which probably means "idle").
