augustss 1339e88a86 Add a new optional method, dev_ioctl, to the audio hardware driver interface. 
It is called when an unrecognized ioctl() is performed on a device,
thus allowing ioctl()s that frob the hardware driver (like loading
microcode).

sommerfeld 851de295eb Change pci_intr_map to get interrupt source information from a "struct 
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

Tested on alpha and i386; welcome to 1.5Q

thorpej 454f740bd4 Use AC97_REG_* constants rather than defining them ourselves. 2000-11-28 16:57:16 +00:00
thorpej 443bd6369f Device driver for the built-in audio on Intel ICH, ICH0, ICH2, 
and i440MX chipsets.  Based on a driver by Michael Shalayeff,
modified somewhat by me to use bus_dma properly, and fix some
audio encoding emulation bugs.

Thanks to Manuel Bouyer for testing and feedback.
