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!

3698 Problems: It seems that Trident chips generates interrupts more than

3700 detected via sample timer (T4D_STIMER) and computing

51 *
52 * Provides conversion from a linear half-volume value in the range
53 * [0,8192] to a logarithmic attenuation value in the range 0 to 6.02dB.
54 * Halving the linear volume is equivalent to an additional 6dB of
55 * logarithmic attenuation. The algorithm used in log_from_linear()
56 * therefore uses this table as follows:
57 *
58 * - loop and for every time the volume is less than half the maximum
59 * volume (16384), add another 6dB and halve the maximum value used
60 * for this comparison.
61 * - when the volume is greater than half the maximum volume, take
62 * the difference of the volume to half volume (in the range [0,8192])
63 * and look up the log_table[] to find the nearest entry.
64 * - take the logarithic component of this entry and add it to the
65 * resulting attenuation.
66 *
67 * Thus this routine provides a linear->log conversion for a range of
68 * [0,16384] using only 386 table entries
69 *
70 * Note: although this table stores log attenuation in 8.8 format, values
71 * were only calculated for 6 bits fractional precision, since that is
72 * the most precision offered by the trident hardware.
