13 * (Maui, Tropez, Tropez Plus)
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
19 * sample management as well.

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

914 on the ROM samples should cover just the sample data or

916 so anyone is free at all times to rewrite sample headers.
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.
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.
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.

1716 Some comments on interrupts. I attempted a version of this
1717 driver that used interrupts throughout the code instead of
1718 doing busy and/or sleep-waiting. Alas, it appears that once
1719 the Motorola firmware is downloaded, the card *never*
1720 generates an RX interrupt. These are successfully generated
1721 during firmware loading, and after that wavefront_status()
1722 reports that an interrupt is pending on the card from time
1723 to time, but it never seems to be delivered to this
1724 driver. Note also that wavefront_status() continues to
1725 report that RX interrupts are enabled, suggesting that I
1726 didn't goof up and disable them by mistake.
1728 Thus, I stepped back to a prior version of
1729 wavefront_wait(), the only place where this really
1730 matters. Its sad, but I've looked through the code to check
1731 on things, and I really feel certain that the Motorola
1732 firmware prevents RX-ready interrupts.

1891 At this point, only "HW VERSION" or "DOWNLOAD OS" commands
1892 will work. So, issue one of them, and wait for TX
1893 interrupt. This can take a *long* time after a cold boot,
1894 while the ISC ROM does its RAM test. The SDK says up to 4
1895 seconds - with 12MB of RAM on a Tropez+, it takes a lot
1896 longer than that (~16secs). Note that the card understands
1897 the difference between a warm and a cold boot, so
1898 subsequent ISC2115 reboots (say, caused by module
1899 reloading) will get through this much faster.
