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

My reason for this is that we have the sample headers

can always be reset if needed. The sample data, however,
|
||
cannot be recovered without a complete reset and firmware

reload of the ICS2115, which is a very expensive operation.
|
||
|
||
So, doing things this way allows us to honor the notion of
|
||
"RESETSAMPLES" reasonably cheaply. Note however, that this
|
||
is done purely at user level: there is no WFB parser in
|
||
this driver, and so a complete reset (back to General MIDI,
|
||
or theoretically some other configuration) is the
|
||
responsibility of the user level library.
|
||
|
||
To try to do this in the kernel would be a little
|
||
crazy: we'd need 158K of kernel space just to hold
|
||
a copy of the patch/program/sample header data.

Some comments on interrupts. I attempted a version of this

driver that used interrupts throughout the code instead of

doing busy and/or sleep-waiting. Alas, it appears that once
|
||
the Motorola firmware is downloaded, the card *never*
|
||
generates an RX interrupt. These are successfully generated
|
||
during firmware loading, and after that wavefront_status()
|
||
reports that an interrupt is pending on the card from time
|
||
to time, but it never seems to be delivered to this
|
||
driver. Note also that wavefront_status() continues to
|
||
report that RX interrupts are enabled, suggesting that I
|
||
didn't goof up and disable them by mistake.
|
||
|
||
Thus, I stepped back to a prior version of
|
||
wavefront_wait(), the only place where this really
|
||
matters. Its sad, but I've looked through the code to check
|
||
on things, and I really feel certain that the Motorola

firmware prevents RX-ready interrupts.
