collected at boot and made available through sysctl(8). At the
moment, the following MIB names are created:
hw.mca.count - The number of error records collected.
hw.mca.first - The lowest sequence number present.
hw.mca.last - The highest sequence number present.
hw.mca.<X> - The error record with sequence number <X>.
Using sysctl(8) allows us to easily detect and analyze the records,
which is very helpful during development of MCA but can also be used
in production as a way to collect machine health statistics.
Do not install games and profiled libraries to the ${CHROOTDIR}
with the initial installworld.
Eliminate the need in the second installworld. For that, make sure
_everything_ is built in the "world" environment, using the right
tool chain.
Added SUBDIR_OVERRIDE helper stuff to Makefile.inc1. Split the
buildworld process into stages, and skip some stages when
SUBDIR_OVERRIDE is set (used to build crypto, krb4, and krb5
dists).
Added NO_MAKEDB_RUN knob to Makefile.inc1 to avoid running
makewhatis(1) at the end of installworld (used when making crypto,
krb4, and krb5 dists).
In release/scripts/doFS.sh, ensure that the correct boot blocks are
used.
Moved the creation of the "crypto" dist from release.5 to
release.2.
In release.3 and doMFSKERN, build kernels in the "world"
environment. KERNELS now means "additional" kernels, GENERIC is
always built.
Ensure we build crunched binaries in the "world" environment.
Obfuscate release/Makefile some more (WMAKEENV) to achieve this.
Inline createBOOTMFS target.
Use already built GENERIC kernel modules to augment mfsfd's
/stand/modules. GC doMODULES as such.
Assorted fixes:
Get rid of the "afterdistribute" target by moving the single use
of it from sys/Makefile to etc/Makefile's "distribute".
Makefile.inc1: apparently "etc" no longer needs to be last for
"distribute" to succeed.
gnu/usr.bin/perl/library/Makefile.inc: do not override the
"install" and "distribute" targets, do it the "canonical" way.
release/scripts/{man,cat}pages-make.sh: make sure Perl manpages and
catpages appear in the right dists. Note that because Perl does
not respect the MANBUILDCAT (and NOMAN), this results in a loss of
/usr/share/perl/man/cat* empty directories. This will be fixed
soon.
Turn MAKE_KERBEROS4 into a plain boolean variable (if it is set it
means "make KerberosIV"), as documented in the make.conf(5)
manpage. Most of the userland makefiles did not test it for "YES"
anyway.
XXX Should specialized kerberized libpam versions be included into
the krb4 and krb5 dists? (libpam.a would be incorrect anyway if
both krb4 and krb5 dists were choosen.)
Make sure "games" dist is made before "catpages", otherwise games
catpages settle in the wrong dist.

timeout loop.
Limit the rate at which we wind the timecounters to approx 1000 Hz.
This limits the precision of the get{bin,nano,micro}[up]time(9)
functions to roughly a millisecond.
timecounter will be used starting at the next second, which is
good enough for sysctl purposes. If better adjustment is needed
the NTP PLL should be used.
around. If the kernel boots successfully, the record of this kernel
is erased, it is intended to be a one-shot option for testing
kernels.
This could be improved by having the loader remove the record of
the next kernel to boot, it is currently removed in /etc/rc immediately
after disks are mounted r/w.
I'd like to MFC this before the 4.6 freeze unless there is violent
objection.

The new devfs doesn't support VFS locking. So don't do locking
assertions for devfs vnodes.
With this change, a kernel with options DEBUG_VFS_LOCKS actually
gets to single-user mode.

- malformed environment strings (ones without an '=') were not rejected.
There shouldn't be any of these, but when the static environment is
empty it always begins with one of these; this one should be considered
as the terminator after the end of the environment, but it isn't.
- the comparison of the name being looked up with the name in the
environment was fuzzy -- only the characters up to the length of the
latter were compared, so _getenv_static("foobar") matched "foo=..."
in the environment and everything matched "" in the empty environment.

Garbage pointers in __si_u were not cleared by destroy_dev(). Not
clearing si_disk made the above fatal because the disk layer uses
si_disk as a flag to indicate that the dev_t has been completely
initialized. disk_destroy() clears si_disk for the parent dev_t
but doesn't get called for children.
Not fixed:
- setting the undocumented sysctl debug.free_devt should cause more
complete destruction of the dev_t including clearing of __si_u, but
actually causes the above to panic a little earlier.
- the loop leaks 10 memory allocations per iteration (4 DEVFS, 2 devbuf
and 4 dev_t).

the symbol index defined by the relocation. The elf_lookup() support
function is to be used by elf_reloc() when symbol lookups need to be
done. The elf_lookup() function operates on the symbol index and
will do a symbol name based lookup when such is required, otherwise
it uses the symbol index directly. This solves the problem seen on
ia64 where the symbol hash table does not contain local symbols and
a symbol name based lookup would fail for those symbols.
Don't pass the symbol name to elf_reloc(), as it isn't used any more.

ahc_eisa.c:
ahc_pci.c:
Conform to new aic7xxx IRQ API.
Adapt to aic7xxx_freebsd -> aic7xxx_osm changes.
aic7770.c:
Disable card generated interrupt early in our probe for
"extra safety"
Commonize some seeprom code with the PCI side of the driver.
aic7xxx.c:
Correctly initialize a few scratch ram locations during
a sequencer restart. This avoids spurious sequencer ram
parity errors in some configurations.
Include the softc in ahc_update_residual calls. We need it
for some diagnostics in this code path.
Flag a data overrun on an auto-request sense failure as a
CAM_AUTOSENSE_FAIL rather than a CAM_DATA_RUN_ERR.
Force a renegotiation after noticing a parity error. This
covers targets that lose our negotiation settings but don't
bother to give us a unit attention condition. This can happen
if a target fails during a reselection of us during a cable
pull.
Convert some code to using constants.
Fix some typos.
Correct target mode message loop handling. ahc_clear_msg_state
was not clearing the "need to go to message out phase" bit once
our loop was over.
Simplify some abort handling code.
Include tag information in target mode immediate notify events.
When shutting down EISA controllers, don't EISA BIOS settings in
the high portions of scratch ram. This fixes warm boot issues on
some systems.
Save a bit of space by only allocating the SCBs that we can use.
Avoid some code paths in ahc_abort_scbs() if we are currently
acting as a target.
Correctly cleanup stranded SCBs in the card's SCB array. These
are SCBs who's mapping has already been torn down by code that
aborted the SCB by seeing it in another list first.
Add a comment about some potential bus reset issues for target
mode on Twin (EISA only) controllers.
aic7xxx.h:
Cleanup the hardware scb definitions a bit.
Allocate a ful 256 byte scb mapping index. This simplifies
the lookup code since the table covers all possible (and potentially
bogus) values.
Make AHC_DEBUG work again.
aic7xxx.reg:
Updates to hardware SCB definition.
New definitions for target mode fixes.
aic7xxx.seq:
In target mode, initialize SAVED_LUN just after we receive
the identify message. It may be required in the error recovery
path when a normal cdb packet (includes lun) is not sent up to
the host for processing.
Respond to irregular messages during a selection in target mode.
Defer looking for space for a cdb packet until we are about to
enter command phase. We want to be able to handle irregular messages
even if we would otherwise return QUEUE_FULL or BUSY.
Add support for sending Ignore Wide Residue messages as a target.
In the disable disconnect case in target mode, set our transfer
rate correctly once data are availble.
aic7xxx_93cx6.c:
aic7xxx_93cx6.h:
Add the ability to write and erase the seeprom.
aic7xxx_inline.h:
Correct Big Endian handling of large cdb sizes (> 12 bytes).
Adaptec to changes in the calc_residual API.
Correct a target mode bug where we always attempted to service
the input queue even if no progress could be made due to lack
of ATIOs.
aic7xxx_osm.c:
Adaptec to new IRQ mapping API. The new API allows the core
to only enable our IRQ mapping once it is safe (sufficient
initialization) to do so.
Slap bootverbose protection around some diagnostics.
Only attempt DT phases if we are wide.
aic7xxx_osm.h:
Enable big endian support.
Adjust for IRQ API change.
aic7xxx_pci.c:
Be more careful about relying on subvendor 9005 information.
We now only trust it for HBAs. This should allow the driver
to attach to some MBs where the subvendor/device information
does not follow the Adaptec spec.
Only enable interrupts on the card once we are fully setup.
Disable external SCB ram usage on the aic7895. I have not
been able to make it 100% reliable.
Adjust to seeprom routines being properly prefixed with "ahc".
Fix a few bugs in the external SCB ram probing routine. We
need to clear any parity errors we've triggered during the
probe to avoid future, fatal, interrupts.
If we detect an invalid cable combination, pretent there are
no cable at all. This will enable all of the terminators
which is probably the safest configuration we can "guess".

strange results as a result.
o Map invalid INTLINE registers to 255 in pci_cfgreg.c. This should allow
us to remove the bogus checks in MI code for non-255 values.
I put these changes out for review a while ago, but no one responded

This should help us work better on machines that don't route
