PIIX support to release its mapping on the edge/level control registers.
Now that these are guaranteed to be unmapped, capture and restore the
registers in piixpcib(4)'s powerhook. The same will need to be done on a
per-chipset basis.
Concerns were raised about calling pci_intr_fixup on resume WRT hotplug
devices, so this has been removed.
Ok cube@.
backend for timecounters.
Due to known bugs in some chipsets, always read until we get 3 successive
samples which are monotonic, as FreeBSD does in its "safe" variant.
This can be refined later, either by chipset quirks or by a test (as
FreeBSD does).
and INSTALL_SMALL. Since floppy images have to fit on one floppy, we
have to really cut down on the drivers on that image, but people
netbooting don't have that problem, so they deserve a more featured
kernel to install with. (namely one with raid support and more ethernet
drivers)
directly.
Including raidframevar.h needs several definitions adding to the compat
framework for the tools builds, which aren't needed here.
XXX It's probably sensible to split off the few defines from raidframevar.h
into a separate header file.
Otherwise, if there are two resources definitions of the same type in _CRS,
the same one from _PRS will be used twice, which of course leads to errors.
Note: _PRS is Possible Resources Set
_CRS is Current Resources Set
XXX acpi_allocate_resources is still very weak, e.g. it completely ignores
StartDependentFn entries which are kind of a switch. But at least it's
slightly better that way.
Tested by jmcneill@.
ntp on my 7248, however, my 7043-140 is still a bit flaky. I suspect the
only way to fix the 7043 is going to be writing a timecounter driver for
the 8254 present on these machines. Either way, this makes some of the
machines better, and the other machines are still about the same as they
were before, so it's a net gain for the port.
partitions. We do this by checking the NetBSD label to see if the
boot partition is of type RAID. If so, we offset reads from the
disk so that the kernel image can be read.
Note that with this code, sun4 machines (with PROM monitor) will only
boot from RAID if the RAID partition is the first one on the disk.
Tested on a SPARCstation 20, a SPARCstation 2 and a 4/330.
