15 * This driver supports the onboard wavetable synthesizer (an ICS2115),
16 * including patch, sample and program loading and unloading, conversion
17 * of GUS patches during loading, and full user-level access to all
18 * WaveFront commands. It tries to provide semi-intelligent patch and

514WaveFront data munging
515
516Things here are weird. All data written to the board cannot
517have its most significant bit set. Any data item with values
518potentially > 0x7F (127) must be split across multiple bytes.
519
520Sometimes, we need to munge numeric values that are represented on
521the x86 side as 8-32 bit values. Sometimes, we need to munge data
522that is represented on the x86 side as an array of bytes. The most
523efficient approach to handling both cases seems to be to use 2
524different functions for munging and 2 for de-munging. This avoids
525weird casting and worrying about bit-level offsets.

917
918 My reason for this is that we have the sample headers
919 available in the WFB file for General MIDI, and so these
920 can always be reset if needed. The sample data, however,
921 cannot be recovered without a complete reset and firmware
922 reload of the ICS2115, which is a very expensive operation.
923
924 So, doing things this way allows us to honor the notion of
925 "RESETSAMPLES" reasonably cheaply. Note however, that this
926 is done purely at user level: there is no WFB parser in
927 this driver, and so a complete reset (back to General MIDI,
928 or theoretically some other configuration) is the
929 responsibility of the user level library.
930
931 To try to do this in the kernel would be a little
932 crazy: we'd need 158K of kernel space just to hold
933 a copy of the patch/program/sample header data.

1710 Some comments on interrupts. I attempted a version of this
1711 driver that used interrupts throughout the code instead of
1712 doing busy and/or sleep-waiting. Alas, it appears that once
1713 the Motorola firmware is downloaded, the card *never*
1714 generates an RX interrupt. These are successfully generated
1715 during firmware loading, and after that wavefront_status()
1716 reports that an interrupt is pending on the card from time
1717 to time, but it never seems to be delivered to this
1718 driver. Note also that wavefront_status() continues to
1719 report that RX interrupts are enabled, suggesting that I
1720 didn't goof up and disable them by mistake.
1721
1722 Thus, I stepped back to a prior version of
1723 wavefront_wait(), the only place where this really
1724 matters. Its sad, but I've looked through the code to check
1725 on things, and I really feel certain that the Motorola
1726 firmware prevents RX-ready interrupts.

1890 longer than that (~16secs). Note that the card understands
