Unlike the <code class="Nm">gus</code> - driver guspnp driver does not require any local memory for the IC, but uses - the codec for both playback and recording. The - <code class="Nm">guspnp</code> driver can simultaneously playback and record - 8- and 16-bit samples at frequencies from 5.51kHz to 48kHz.</p> -<p class="Pp">The <code class="Nm">guspnp</code> driver relies on - <code class="Nm">isapnp</code> to allocate suitable resources for it. This - version of the driver only uses the first logical device of the five the - Interwave IC has. The four unused logical devices are the ATAPI CD-ROM - device, PnP Joystick device, legacy soundcard emulation device - (SoundBlaster) and MIDI serial device. Support for at least ATAPI CD-ROM and - Joystick is being worked on. This version of the driver will use 1 IRQ and 2 - DRQs.</p> -</section> -<section class="Sh"> -<h1 class="Sh" id="HARDWARE"><a class="permalink" href="#HARDWARE">HARDWARE</a></h1> -<p class="Pp">Cards supported by the <code class="Nm">guspnp</code> driver - include:</p> -<ul class="Bl-item Bd-indent"> - <li>Gravis Ultrasound PNP, and compatibles</li> -</ul> -</section> -<section class="Sh"> -<h1 class="Sh" id="SEE_ALSO"><a class="permalink" href="#SEE_ALSO">SEE - ALSO</a></h1> -<p class="Pp"><a class="Xr">audio(4)</a>, <a class="Xr">gus(4)</a>, - <a class="Xr">isapnp(4)</a></p> -</section> -<section class="Sh"> -<h1 class="Sh" id="REFERENCES"><a class="permalink" href="#REFERENCES">REFERENCES</a></h1> -<p class="Pp">Interwave(tm) IC Am78C201/202 Programmer's Guide Rev. 2. 1996. - Advanced Micro Devices.</p> -</section> -<section class="Sh"> -<h1 class="Sh" id="HISTORY"><a class="permalink" href="#HISTORY">HISTORY</a></h1> -<p class="Pp">The <code class="Nm">guspnp</code> driver appeared in - <span class="Ux">NetBSD 1.3</span>.</p> -</section> -<section class="Sh"> -<h1 class="Sh" id="AUTHORS"><a class="permalink" href="#AUTHORS">AUTHORS</a></h1> -<p class="Pp"><span class="An">Kari Mettinen</span> - <<a class="Mt" href="mailto:Kari.Mettinen@helsinki.fi">Kari.Mettinen@helsinki.fi</a>>, - University of Helsinki.</p> -</section> -<section class="Sh"> -<h1 class="Sh" id="BUGS"><a class="permalink" href="#BUGS">BUGS</a></h1> -<p class="Pp">Sometimes you can cause a hiss on either left or right channel, or - both. You can usually make it disappear by playing random data, however this - might not be a very nice thing to your audio equipment, but it is the only - way I have found out to be effective.</p> -<p class="Pp">Only the Codec is used in this version of the driver, therefore - only 2 channels are supported (left and right). Also sound quality is - probably worse at lower kHz compared to playing through the synthesizer - which does interpolation.</p> -<p class="Pp">If the implementation has a 'bad' oscillator, using frequencies - 44.8kHz and 38.4kHz will result in incorrect playback frequency. The author - has a GUS PnP Pro which displays this behavior.</p> -<p class="Pp">Other members of the Interwave family have not been tested and - don't have the glue needed to make them work. Should someone need to - implement it, not many changes in the existing code are needed. Output - voltage control in register CFIG2 [7] should be set differently for some - other members of the family.</p> -<p class="Pp">Other architectures than i386 haven't been tested. The bus_space - abstraction has been used from the beginning, so it should work.</p> -</section> -</div> -<table class="foot"> - <tr> - <td class="foot-date">June 22, 2005</td> - <td class="foot-os">NetBSD 10.1</td> - </tr> -</table> |
