the following bugs.
- When constructing a resource configuration, respect the order
in which resource descriptors are read, in order to establish
the correct mapping between the descriptors and configuration
registers.
"Plug and Play ISA Specification, Version 1.0a", Sec 4.6.1, May 5,
1994. "Clarifications to the Plug and Play ISA Specification,
Version 1.0a", Sec 6.2.1, Dec. 10, 1994.
- Do not ignore null (empty) descriptors; they are valid descriptors
acting as filler.
"Clarifications to the Plug and Play ISA Specification, Version 1.0a",
Sec 6.2.1.
- Correctly set up logical device configuration registers for null
resources.
"Clarifications to the Plug and Play ISA Specification, Version 1.0a"
- Handle null resources properly in the resource allocator for the
ISA bus.
(I had been busy for my own research activity until the last weekend)
Supported devices:
SB Midi Port (sbc + midi)
SB OPL3 (sbc + midi)
16550 UART (midi, needs a trick in your hint)
CS461x Midi Port (csa + midi)
OSS-compatible sequencer (seq)
Supported playing software:
playmidi (We definitely need more)
Notes:
/dev/midistat now reports installed midi drivers. /dev/sndstat reports
only pcm drivers. We need the new name(pcmstat?).
EMU8000(SB AWE) does not sound yet but does get probed so that the OPL3
synth on an AWE card works.
TODO:
MSS/PCI bridge drivers
Midi-tty interface to support general serial devices

is an application space macro and the applications are supposed to be free
to use it as they please (but cannot). This is consistant with the other
BSD's who made this change quite some time ago. More commits to come.
* Move pnp_eisaformat() to pnp.c, declared in <isa/pnpvar.h>.
* Turn the pnpbios code into an enumerator for the isa bus. This allows
all devices known to the bios to be probed automatically.
Currently the pnpbios code is dependant on the PNPBIOS option. As the code
is tested more and when more drivers are converted this will be made the
default. I have PnP changes in the wings for fdc, atkbd, psm, pcaudio, and
joy. Sio already works with pnpbios.
new system is integrated with the ISA bus code more cleanly and allows
the future addition of more enumerators such as PnPBIOS and ACPI.
This commit also enables the new pcm driver since it is somewhat tied to
the new PnP code.
