<sys/mutex.h> due to #include spam in <sys/mutex.h>. (More precisely,
<sys/time.h> is the prerequisite, but that is provided by standard
#include spam in <sys/param.h>.)
Fixed bitrot in prototype for mtx_init().
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.

* Rip out MACHINE_CPU stuff from sys.mk and include a new <bsd.cpu.mk>
after we pull in /etc/make.conf. We need to do it afterwards so we can
react to the user setting of the:
* CPUTYPE variable, which contains the CPU type which the user wants to
optimize for. For example, if you want your binaries to only run on an
i686-class machine (or higher), set this to i686. If you want to support
running binaries on a variety of CPU generations, set this to the lowest
common denominator. Supported values are listed in make.conf.
* bsd.cpu.mk does the expansion of CPUTYPE into MACHINE_CPU using the
(hopefully) correct unordered list of CPU types which should be used on
that CPU. For example, an AMD k6 CPU wants any of the following:
k6 k5 i586 i486 i386
This is still an unordered list so the client makefile logic is simple -
client makefiles need to test for the various elements of the set in
decreasing order of priority using ${MACHINE_CPU:M<foo>}, as before.
The various MACHINE_CPU lists are believed to be correct, but should be
checked.
* If NO_CPU_CFLAGS is not defined, add relevant gcc compiler optimization
settings by default (e.g. -karch=k6 for CPUTYPE=k6, etc). Release
builders and developers of third-party software need to make sure not to
enable CPU-specific optimization when generating code intended to be
portable. We probably need to move to an /etc/world.conf to allow the
optimization stuff to be applied separately to world/kernel and external
compilations, but it's not any worse a problem than it was before.
* Add coverage for the ia64/itanium MACHINE_ARCH/CPUTYPE.
* Add CPUTYPE support for all of the CPU types supported by FreeBSD and gcc
(only i386, alpha and ia64 first, since those are the minimally-working
ports. Other architecture porters, please feel free to add the relevant

through the use of a new build directive, MACHINE_CPU, which contains a

This feature will be extended to cover the ports tree in the future.
Currently OpenSSL provides optimizations for i386, i586 and i686-class
CPUs. Currently it has not been tested on an i386 or i486.
Teach make(1) to provide sensible defaults for MACHINE_CPU if it is not
defined (namely, the lowest common denominator CPU we support for each
architecture). Currently this is i386 for the i386 architecture and ev4
for the alpha. sys.mk also sets the variable as a last resort for
consistency with MACHINE_ARCH and bootstrapping from very old versions of
make.
Benchmarks show a significant speed increase even in the i386 case, with
additional improvements for i586 and i686 systems. For maximum performance
define MACHINE_CPU=i686 i586 i386 in /etc/make.conf.
