sys/sparc64/pci psycho.c psychovar.h
Log:
- Add a workaround (change the interrupt map mask to compare the full
INO) for incorrect interrupt map entries on E250 machines. These
incorrect entries caused the INO of the on-board HME to be also
assigned to the second on-board NS16550 and to the on-board printer
port controller. Further down the road caused hme(4) to fail to attach
to the on-board HME in FreeBSD 5 and 6 as INTR_FAST and non-INTR_FAST
handlers can't share the same IRQ there (it's unknown what whould
happen in -CURRENT now that INTR_FAST and non-INTR_FAST handlers can
share an IRQ but I'd expect funny problems with uart(4)).
- Make sure there are exactly 4 PCI ranges instead of just checking
that the bridge has a 'ranges' property in the OFW device tree at all.
Besides the fact that currently the 64bit memory range isn't used by
this driver it we can't really work with less than 4 ranges and don't
have memory for more than 4 bus handles for the ranges in the softc.
- Remove sc_range and sc_nrange from softc; for the bridges supported
by this driver we no longer need to know the ranges besides the bus
handles obtained from them once this driver is attached. That way we
also can free the memory allocated for sc_range during attach again.
- Remove sc_dvmabase from the softc and pass it to psycho_iommu_init()
via an additional argument as we no longer need to know the DVMA base
in this driver once the IOMMU is initialized.
- Remove sc_dmatag from the softc, there isn't much sense in keeping
the nexus dma tag around locally.
