    <title>luna68k: add psgpam(4) audio for LUNA, using YM2149 PSG/SSG sound chip.<br/><br/>"PSG PAM" is a audio driver using "Pulse Amplitude Modulation" with the<br/>YM2149 PSG/SSG chip connected to the I/O processor HD647180X on LUNA.<br/>The driver plays up to 30 kHz PCM audio by manipulating PSG channel volumes<br/>at extremely high speed with 6.144 MHz HD647180X, a Z80 compatible sub CPU.<br/> https://www.youtube.com/watch?v=fR7PqaLpijQ<br/> https://www.youtube.com/watch?v=kCDZCgkwgBA<br/><br/>Compatibilities with the existing XPIOCDOWNLD ioctl(2) to download and<br/>exec user programs (PSG sound driver player ported from PC-6001 etc.)<br/>on the HD647180X is still provided.<br/> https://twitter.com/tsutsuii/status/1533247362965315584<br/><br/>This psgpam(4) driver for NetBSD/luna68k was written by @moveccr<br/>during isaki-audio2 branch developments, and it was also demonstrated<br/>at Open Source Conference 2018 Kyoto:<br/> https://github.com/isaki68k/netbsd-src/tree/audio2<br/> https://mail-index.netbsd.org/netbsd-advocacy/2018/08/07/msg000781.html<br/> https://twitter.com/tsutsuii/status/1025504875625365505<br/><br/>Note specifications of interrupts from the HD647180X to the host LUNA<br/>was confirmed by Kenji Aoyama on his LUNA-88K2 running OpenBSD/luna88k.<br/><br/>I would like to thank all people still working on ancient LUNA machines!</title>
