SVN rev 190109 on 2009-03-19 20:52:46Z by marius
- Ensure we find no unexpected partner.
- Failing to register as interrupt controller during attach shouldn't
be fatal so just inform about this instead of panicing.
- Disable rerun of the streaming cache as workaround for a silicon bug
of certain Psycho versions.
- Remove the comment regarding lack of newbus'ified bus_dma(9) as being
able to associate a DMA tag with a device would allow to implement
CDMA flushing/syncing in bus_dmamap_sync(9) but that would totally
kill performance. Given that for devices not behind a PCI-PCI bridge
the host-to-PCI bridges also only do CDMA flushing/syncing based on
interrupts there's no additional disadvantage for polling(4) callbacks
in the case schizo(4) has to do the CDMA flushing/syncing but rather a
general problem.
- Don't panic if the power failure, power management or over-temperature
interrupts doesn't exist as these aren't mandatory and not available
with all controllers (not even Psychos). [1]
- Take advantage of KOBJMETHOD_END.
- Remove some redundant variables.
- Add missing const.
