Linux-2.6.12-rc2

Browse Source 
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

*
*
* The OPL-3 mode is switched on by writing 0x01, to the offset 5
* of the right side.
*
* Another special register at the right side is at offset 4. It contains
* a bit mask defining which voices are used as 4 OP voices.
*
* The percussive mode is implemented in the left side only.
*
* With the above exceptions the both sides can be operated independently.
*
* A 4 OP voice can be created by setting the corresponding
* bit at offset 4 of the right side.
*
* For example setting the rightmost bit (0x01) changes the
* first voice on the right side to the 4 OP mode. The fourth
* voice is made inaccessible.
*
* If a voice is set to the 2 OP mode, it works like 2 OP modes
* of the original YM3812 (AdLib). In addition the voice can
* be connected the left, right or both stereo channels. It can
* even be left unconnected. This works with 4 OP voices also.
*
* The stereo connection bits are located in the FEEDBACK_CONNECTION
* register of the voice (0xC0-0xC8). In 4 OP voices these bits are
* in the second half of the voice.

You will not be able to compile this file correctly without gcc, because
it is necessary to pack the "wavefront_alias" structure to a size
of 22 bytes, corresponding to 16-bit alignment (as would have been
the case on the original platform, MS-DOS). If this is not done,
then WavePatch-format files cannot be read/written correctly.
The method used to do this here ("__attribute__((packed)") is
completely compiler dependent.
All other wavefront_* types end up aligned to 32 bit values and
still have the same (correct) size.
#else
/* However, note that as of G++ 2.7.3.2, g++ was unable to
correctly parse *type* __attribute__ tags. It will do the
right thing if we use the "packed" attribute on each struct
member, which has the same semantics anyway.

Because most/all of the sample data we pass in via pointers has
never been copied (just mmap-ed into user space straight from the
disk), it would be nice to allow handling of multi-channel sample
data without forcing user-level extraction of the relevant bytes.
So, we need a way of specifying which channel to use (the WaveFront
only handles mono samples in a given slot), and the only way to do
this without using some struct other than wavefront_sample as the
interface is the awful hack of using the unused bits in a
wavefront_sample:
Val Meaning
--- -------
0 no channel selection (use channel 1, sample is MONO)
1 use first channel, and skip one
2 use second channel, and skip one
3 use third channel, and skip two
4 use fourth channel, skip three
5 use fifth channel, skip four
6 use six channel, skip five
This can handle up to 4 channels, and anyone downloading >4 channels
of sample data just to select one of them needs to find some tools
like sox ...
NOTE: values 0, 1 and 2 correspond to WF_CH_* above. This is
important.
