- Add checks to pfs_open() to prevent opening read-only files for writing
or vice versa (pfs_{read,write} would block the actual reads and writes,
but it's still a bug to allow the open() to succeed). Also, return
EOPNOTSUPP if the caller attempts to lock the file.
- Add more trace points.
easier and hopefully this code is done changing radically.
Don't use the mmu tlb register to address the kernel page table, nor
the 8k pointer register. The hardware will do some of the page table
lookup by storing the the base address in an internal register and
calculating the address of the tte in the table. However it is limited
to a 1 meg tsb, which only maps 512 megs. The kernel page table only
has one level, so its easy to just do it by hand, which has the advantage
of supporting abitrary amounts of kvm and only costs a few more instructions.
Increase kvm to 1 gig now that its easy to do so and so we don't waste
most of a 4 meg page.
Fix some traces. Fix more proc locking.
Call tsb_stte_promote if we get a soft fault on a mapping in the upper
levels of the tsb. If there is an invalid or unreferenced mapping
in the primary tsb, it will be replaced.
Immediately fail for faults occuring in {f,s}uswintr.
one 4 meg page can map both the kernel and the openfirmware mappings.
Add the openfirmware mappings to the kernel tsb so we can call the firmware
on the kernel trap table and access kernel memory normally.
Implement pmap_swapout_proc, pmap_swapin_proc, pmap_swapout_thread,
pmap_swapin_thread, pmap_activate, pmap_page_exists, and pmap_phys_address.
Add a guard page at the bottom of the kernel stack. Its unclear how easy
it will be to detect these faults and do something useful.
Setup the registers on exec how the c runtime expects.
Implement various {fill,set}_*regs.
Fix proc locking.
name is "mount_mfs" or "mfs". Previously, the condition was that
the program name must start with "mount_", but this both missed
the case where mount(8) invokes mdmfs with argv[0] = "mfs", and it
included cases such as "mount_md" where compatibility is not
required.

a block or character device; the rest of tunefs works just fine on
filesystem images in regular files. Instead, if getfsfile() failed
and if the specified filesystem is a directory then print a more
useful "unknown file system" error.
Also, _PATH_DEV already contains a trailing slash, so don't add
another one when constructing a device path, and use errx() instead
of err() in a case where errno is meangingless.

I was told by dcs that this script's original author is no longer
interested in FreeBSD and would not wish to review this patch.
when I changed the allocator bits. This implements per-CPU mbtypes
stats by keeping net number of decrements/increments of a given mbtype
per-CPU and then summing all of the per-CPU mbtypes to produce the total
net number of allocated mbufs of the given mbtype.
Counters are carefully balanced to avoid/prevent underflows/overflows.
mbtypes stats are re-enabled with the idea that we may occasionally
(although very rarely) observe slight inconsistencies in the stat
reporting. Most of the time, we should be fine, though.
Also make appropriate modifications to netstat(1) and systat(1) to do
the necessary reporting.

all the mii devices for small fixed-purpose kernels.

1. To cross-build, one now needs to set TARGET_ARCH, and not the
MACHINE_ARCH. MACHINE_ARCH should never be changed manually!
2. Initialize DESTDIR= explicitly for bootstrap-tools, build-tools,
and cross-tools stages. This fixes broken header and library
dependencies problem. We build them in the host environment,
and obviously want them to depend on host headers and libraries.
The problem with broken header dependencies for bootstrap-tools
and cross-tools was already partially solved (see BOOTSTRAPPING
tests in bsd.prog.mk and bsd.lib.mk), but it was still there for
build-tools if the user ran "make world DESTDIR=/foo". Also,
for all of these stages, the library dependencies were broken
because of how bsd.libnames.mk define DPADD members.
We still provide a glue to install bootstrap- and cross-tools
under the ${WORLDTMP}.
Removed PATH overrides for bootstrap-, build-, and cross-tools
stages. There is just no reason why we would need to override
it, and the hacks to clean up the ${WORLDTMP} in the -DNOCLEAN
case are no longer needed with fixes from this step.
That is, we now never use ${WORLDTMP} headers and libraries,
and we don't use any ${WORLDTMP} installed binaries during
these stages. Again, these stages depend solely on the host
environment, including compiler, headers, and libraries.
3. Moved "miniperl" back from cross-tools (it has nothing to do
with a cross-compiler) to build-tools where it belongs. The
change from step 1 let to do this. Also, to make this work,
build-tools targets of "cc_tools" and "miniperl" were modified
to call "depend". Here follow the detailed explanations.
There are two categories of build tools, for now. In the first
category there are "cc_tools" and "miniperl". They occupy the
whole (sub)directory, and nothing needs to be done in this
subdirectory later during the "all" stage. They are also
constructed using system makefiles. We must build the .depend
early in the build-tools stage because:
1) They use (and depend on) the host environment.
2) If we don't do this in build-tools, the "depend" stage of
buildworld will do this for us; wrong library and header
dependencies will be recorded (DESTDIR=${WORLDTMP}) and,
what's worse, the "all" stage may then clobber the
build-architecture format tools (that we built in the
build-tools stage) with the target-architecture format
ones, breaking cross build.
In the second category there are all other build-tools. They
share their directory with the "main" module that needs them
in the "all" stage, and they don't show up themselves in the
.depend file. The portion of this fix was already committed
in gnu/usr.bin/cc/cc_tools/Makefile,v 1.52.
4. "libperl" is no longer a build tool, and "miniperl" is the
stand-alone application. I had to make this change because
build-tools and "all" stages share the same object directory.
Without this change, if we cross compile, libperl.a is first
built for the build architecture during the build-tools stage
(for the purposes of immediate linkage with "miniperl").
Later on, the "all" stage sees this library as up-to-date,
and doesn't rebuild it. The effect is that the wrong format
static libperl library is installed with installworld.
5. Fixed "includes" to install secure/lib/libtelnet headers if
required.
