(`SUNW,sabre') for now, and it doesn't really quite work there yet anyway.
the bus space/dma code is cloned from the sbus driver. the IOMMU code also
is cloned from the sbus code, but separated out into iommu.c so that we can
share it with the sbus driver. hopefully, much of the bus space/dma code
can also be re-shared with the sbus driver and the ebus driver but for now
these copies will do.
support for the real UltraSPARC PCI (`SUNW,psycho') is unwritten, though
most of this code is shared with it.
we can probe PCI config space and try to configue devices, but interrupts
don't work yet...
the bus space/dma code is cloned from the PCI code to do the same thing
which itself was cloned from the sbus bus space/dma code. the bus dma
code is non-functional at this point.
component failures! Also: remember to configure the disk queues for
the spares -- failure to do that is Bad(tm).
Huge Thanks to Martin Laubach for helping track this down.
be clobbered. since 4.4-Lite(?) disklabel.c has gone to extra effort
to avoid clobbering the boot area when using -r, but the 4.4-Lite manual
pages were apparently not updated to note that!
setting recursive has no effect! The kernel lock manager doesn't allow
an exclusive recursion into a shared lock. This situation must simply
be avoided. The only place where this might be a problem is the (ab)use
of uvm_map_pageable() in the Utah-derived pmaps for m68k (they should
either toss the iffy scheme they use completely, or use something like
uvm_fault_wire()).
In addition, once we have looped over uvm_fault_wire(), only upgrade to
an exclusive (write) lock if we need to modify the map again (i.e.
wiring a page failed).
don't unlock a kernel map (!!!) and then relock it later; a recursive lock,
as it used in the user map case, is fine. Also, don't change map entries
while only holding a read lock on the map. Instead, if we fail to wire
a page, clear recursive locking, and upgrade back to a write lock before
dropping the wiring count on the remaining map entries.
bytes/sector correctly.
Submitted by Detlev Würkner in PR 7653.
Non-trivial merge with the 1.30 change (handle old AmigaDOS fs partitions
with simulated sectorsperblock > 1) by myself, so don't blame Detlev if it
doesn't work (but I checked!).
XXX We still need changes to the file systems to handle this fully.
the latter only seemed to work for TIS Gauntlet and not TIS fwtk.
thanks to simonb@netbsd.org for testing this. fixes [bin/5556].
* if EOF (e.g, ^D) is entered at a username/password/account prompt which
happens to use fgets(), exit the login rather than treating EOF as CR.
* don't use the comma operator where separate statements are valid
* always use snprintf to copy stuff into malloced buffers, just in case
typos creep in and mean that the buffer ends up being overflowed
is heavily influenced by src/distrib/notes/Makefile.inc, from Ross Harvey.
While here, fix a typo and nuke some trailing spaces, to make mdoc more comfortable.
