1.) prefix all functions in the library with devstat_ (compatability
functions are available for all functions that were chaned in an
incompatible way, but are deprecated).
2.) Add a pointer to a kvm_t as the first argument to functions that
used to get their information via sysctl; they behave the same
as before when NULL is passed as this argument, otherwise, the
information is obtained via libkvm using the supplied handle.
3.) Add a new function, devstat_compute_statistics(), that is intended
to replace the old compute_stats() function. It offers more
statistics data, and has a more flexible interface.
libdevstat does now require libkvm; a library depedency is added, so
that libkvm only needs to be explicitely specified for statically linked
programs.
The library major version number is bumped.

want host headers during `buildworld'.
- During `buildworld', install headers in a "copy" mode
until we decide what to do with the (currently broken)
SHARED=symlinks.
- Temporarily run `buildworld' with -DNO_WERROR, which
effectively disabled the -Werror bit of recently added
WARNS=X feature. This is required because adding the
-nostdinc bit back revealed bugs in some header files
that were hiding after not using -nostdinc.
It is unclear currently how exactly (and why) -nostdinc
affects gcc(1) warnings.
file during the bootstrapping process of a buildworld and contained the
last isc include file to be installed. It was meant to be a directory for
the isc include files.
Some of the major changes include:
- The SCSI error handling portion of cam_periph_error() has
been broken out into a number of subfunctions to better
modularize the code that handles the hierarchy of SCSI errors.
As a result, the code is now much easier to read.
- String handling and error printing has been significantly
revamped. We now use sbufs to do string formatting instead
of using printfs (for the kernel) and snprintf/strncat (for
userland) as before.
There is a new catchall error printing routine,
cam_error_print() and its string-based counterpart,
cam_error_string() that allow the kernel and userland
applications to pass in a CCB and have errors printed out
properly, whether or not they're SCSI errors. Among other
things, this helped eliminate a fair amount of duplicate code
in camcontrol.
We now print out more information than before, including
the CAM status and SCSI status and the error recovery action
taken to remedy the problem.
- sbufs are now available in userland, via libsbuf. This
change was necessary since most of the error printing code
is shared between libcam and the kernel.
- A new transfer settings interface is included in this checkin.
This code is #ifdef'ed out, and is primarily intended to aid
discussion with HBA driver authors on the final form the
interface should take. There is example code in the ahc(4)
driver that implements the HBA driver side of the new
interface. The new transfer settings code won't be enabled
until we're ready to switch all HBA drivers over to the new
interface.
src/Makefile.inc1,
lib/Makefile: Add libsbuf. It must be built before libcam,
since libcam uses sbuf routines.
libcam/Makefile: libcam now depends on libsbuf.
libsbuf/Makefile: Add a makefile for libsbuf. This pulls in the
sbuf sources from sys/kern.
bsd.libnames.mk: Add LIBSBUF.
camcontrol/Makefile: Add -lsbuf. Since camcontrol is statically
linked, we can't depend on the dynamic linker
to pull in libsbuf.
camcontrol.c: Use cam_error_print() instead of checking for
CAM_SCSI_STATUS_ERROR on every failed CCB.
sbuf.9: Change the prototypes for sbuf_cat() and
sbuf_cpy() so that the source string is now a
const char *. This is more in line wth the
standard system string functions, and helps
eliminate warnings when dealing with a const
source buffer.
Fix a typo.
cam.c: Add description strings for the various CAM
error status values, as well as routines to
look up those strings.
Add new cam_error_string() and
cam_error_print() routines for userland and
the kernel.
cam.h: Add a new CAM flag, CAM_RETRY_SELTO.
Add enumerated types for the various options
available with cam_error_print() and
cam_error_string().
cam_ccb.h: Add new transfer negotiation structures/types.
Change inq_len in the ccb_getdev structure to
be "reserved". This field has never been
filled in, and will be removed when we next
bump the CAM version.
cam_debug.h: Fix typo.
cam_periph.c: Modularize cam_periph_error(). The SCSI error
handling part of cam_periph_error() is now
in camperiphscsistatuserror() and
camperiphscsisenseerror().
In cam_periph_lock(), increase the reference
count on the periph while we wait for our lock
attempt to succeed so that the periph won't go
away while we're sleeping.
cam_xpt.c: Add new transfer negotiation code. (ifdefed
out)
Add a new function, xpt_path_string(). This
is a string/sbuf analog to xpt_print_path().
scsi_all.c: Revamp string handing and error printing code.
We now use sbufs for much of the string
formatting code. More of that code is shared
between userland the kernel.
scsi_all.h: Get rid of SS_TURSTART, it wasn't terribly
useful in the first place.
Add a new error action, SS_REQSENSE. (Send a
request sense and then retry the command.)
This is useful when the controller hasn't
performed autosense for some reason.
Change the default actions around a bit.
scsi_cd.c,
scsi_da.c,
scsi_pt.c,
scsi_ses.c: SF_RETRY_SELTO -> CAM_RETRY_SELTO. Selection
timeouts shouldn't be covered by a sense flag.
scsi_pass.[ch]: SF_RETRY_SELTO -> CAM_RETRY_SELTO.
Get rid of the last vestiges of a read/write
interface.
libkern/bsearch.c,
sys/libkern.h,
conf/files: Add bsearch.c, which is needed for some of the
new table lookup routines.
aic7xxx_freebsd.c: Define AHC_NEW_TRAN_SETTINGS if
CAM_NEW_TRAN_CODE is defined.
sbuf.h,
subr_sbuf.c: Add the appropriate #ifdefs so sbufs can
compile and run in userland.
Change sbuf_printf() to use vsnprintf()
instead of kvprintf(), which is only available
in the kernel.
Change the source string for sbuf_cpy() and
sbuf_cat() to be a const char *.
Add __BEGIN_DECLS and __END_DECLS around
function prototypes since they're now exported
to userland.
kdump/mkioctls: Include stdio.h before cam.h since cam.h now
includes a function with a FILE * argument.

would have taken care of the possibility of buildkernel crossing over

of trouble when people put "KERNEL=MYKERNEL" in make.conf. Bite the bullet
and change it to KERNCONF instead, before it gets too far entrenched.
The kernel Makefiles use ${KERNEL} as the name of what to install the
kernel as, eg: /boot/${KERNEL}/kernel or /${KERNEL}. This leads to much
unhappiness with things like /LOCAL instead of /kernel. buildkernel is
severely limited as it is only useful directly after a buildworld.

not right because rtermcap would be reading the *host* termcap, not
from the termcap in the src tree. Besides, /usr/sbin/sysinstall
(not the crunched one in /stand) should use the runtime termcap
not the precompiled set.
The distribute target is basicly the same as an install. For
perl, this means that miniperl is needed. Since miniperl is
only present in the object directory, we need to make sure
the path is set correctly. To do this, we have make release
use a new distribworld target that sets the path before doing
a make distribute.
o Move building libperl and miniperl from build-tools to
cross-tools. libperl uses MACHINE_ARCH to determine the
right configuration, which doesn't match the build
machine when cross-building if they are built as build-
tools.
o Since miniperl needs to be built as a cross-tool, it
needs to be installed under /usr/obj so that it can be
used (cross-tools have a special object directory to
avoid build conflicts. As a downside, you can't easily
run cross-tools from their object directory). Remove
the install and distribute override targets. To avoid
having miniperl installed by installworld, remove it
from SUBDIR.
o We can't pickup miniperl from the object directory but
since it's installed, depend on PATH. This is save,
because the makefiles are run with a known path.
o Build libperl again as part of the library target. A
_libperl variable existed, but it was never defined.
o Add chmod to the list of saved tools, because perl
conditionally uses it during install.
The bootstrap-tools and cross-tools targets are modified to
avoid building profiled and shared libraries. While here,
have these targets build static binaries instead of shared
binaries.

when using the egcs and gcc-devel ports, along with GCC built from stock
public FSF sources. With out this change, FreeBSD will be removed from
the list of systems GCC 3.0 must be evaluated on before release. With
the effort some of us put into getting FreeBSD on this list, we should
not turn this effort into a waste, else we might not be worth fighting
for in the future. (note that Alpha and IA-64 versions of crt{i,n}.S
are needed)
* Switch from our own crt{begin,in} to those created from GCC's crtstuff.c.
This will allow us to switch to DWARF2 exceptions in the future, along with
staying in sync with any future GCC requirements.
* Break out our ELF branding bits into a seperate file. Currently this
is now included by our crt1.c files (since this functionality was part of
our native crtbegin.c). Later crtbrand.o will be merged in the creation
of crti.o.
If a user decides to forego a make depend during "make buildkernel",
they should get what they deserve if no previous make depend has
been run for that kernel. Instead, the build process includes
special instructions to unconditionally rebuild aicasm. When aicasm
moved to its own directory, this hack broke.
Correct the hack until a get buy off on killing it.
