This is a master ticket for tracking the updates of the various audio
drivers, such that they can co-exist with OpenSound. {{{
(un)reserve_device }}} needs to be utilized by Haiku's drivers, such as
browser:haiku/trunk/src/add-ons/kernel/drivers/audio/hda/driver.cpp#L56
{{{
if (info.class_base == PCI_multimedia
&& info.class_sub == PCI_hd_audio) {
#ifdef __HAIKU__
if ((*gPci->reserve_device)(info.bus, info.device,
info.function, "hda",
&gCards[gNumCards]) < B_OK) {
dprintf("HDA: Failed to reserve
PCI:%d:%d:%d\n",
info.bus, info.device,
info.function);
continue;
}
#endif
}}}
and browser:haiku/trunk/src/add-
ons/kernel/drivers/audio/hda/driver.cpp#L95
{{{
#ifdef __HAIKU__
(*gPci->unreserve_device)(gCards[i].pci_info.bus,
gCards[i].pci_info.device,
gCards[i].pci_info.function, "hda", &gCards[i]);
#endif
}}}
