bounds information, ie. the zone of the disk that OpenBSD can use. Have each
pre-disklabel parser (MBR, DPME, or per-arch MD disklabel parsers) figure out
this area and pass it up to userland. Then, delete all the same disk parsing
code from disklabel(8) since the kernel passes it up. Lots and lots of - signs
in the disklabel(8) code.
Tested on as many platforms as possible, the fallout will be repaired as time
goes on. To test, use disklabel -d <drive> and validate that the bounds do not
overlap any boot blocks. This same information is used by disklabel -A...
OK for the concept from krw, miod, and drahn

landisk, and the sparc implementation is obviously wrong. That's where I
stopped looking, so who knows what else was broken. A simple comparison of
the existing mtx_enter with the new mtx_enter_try would have told anybody.

to make sure the register holding the ld_l and st_c addresses doesn't
get reused when gcc's register allocator is too aggressive.

Saves every damned driver calling bzero(), and continues the M_ZERO,

For the possibility of sleeping, the first two flags are UVM_PLA_WAITOK
and UVM_PLA_NOWAIT. It is an error not to show intention, so assert that
one of the two is provided. Switch over every caller in the tree to
using the appropriate flag.

MD code would free resources that couldn't be freed until we were no
longer running in that processor. However, it's is unused on all
architectures since mikeb@'s tss changes on x86 earlier in the year.

map to real hardware interrupt levels to have soft ipl values overlapping
hard ipl values without breaking spl asserts.

try to be smart for the address range, uvm_pglistalloc() is smart enough
nowadays.

pretty confident that it works on all arches.

happens instead of panicing; while there, start providing more details
for ev6 processor machine checks as well.
This allows power supplies to be unplugged and exchanged while the system
is running, without causing the kernel to crash.

What happened was that the output of mkdep was fed to a sed expression
that trimmed a bit more than required and also failed to work when
attempting to do make depend with pcc.
Example:
genassym_c.o: /tmp/genassym.whatever ../../../../../sys/param.h \
was changed to:
assym.h: \
but what was intended was:
assym.h: ../../../../../sys/param.h \
For the pcc -M output things were a bit different and after the make
depend the genassym entry would still remain and make would fail. This
affected all platforms except amd64 and sgi.
Okay miod@.

(if the stge(4) entry is commented, so is the ipgphy(4) entry then).

previously, we had a static list of pcidevs and which agp driver would
be interanlly attached. Instead, split the agp drivers so they work like
audio(4), where we attach a driver, which sets up some callbacks and
initial state, then attaches the interface (agp(4)). Since this allows
us to attach different drivers in different places, and give them
/proper/ probe functions move most of the drivers back to attaching at
pchb, where they should, and intagp (formerly agp_i810) stays attaching
at vga, since it's part of the intel integrated graphics chips.
Diff shrinks the kernel slightly, gets rid of the annoying "no integrated
graphics" warning, and allows more cleanup later.
Tested by many. fix for alpha build (the only other vga_pci.c consumer)
suggested by miod.

add a new arg to the backend so it can tell pool to slow down. when we get
this flag, yield *after* putting the page in the pool's free list. whatever
we do, don't let the thread sleep.
this makes things better by still letting the thread run when a huge pf
request comes in, but without artificially increasing pressure on the backend
by eating pages without feeding them forward.

which are uniform for the profclock on each cpu in a SMP system (but using
a different seed for each cpu). on all cpus, avoid seeding with a value out
of the [0, 2^31-1] range (since that is not stable)

anything special to prod a cpu to leave the idle loop in signotify.
powerpc, i386, amd64 and sparc64 will follow soon so that everyone has
the same interface to wake an idling cpu.
|

For now, sparc64 is arbitrarily set to 256 (only architecture that didn't have
a practical limit in the code on the number of cpus).

long ints for alpha. we've got only one instruction (cvttq) to
convert double-t to quadword, and float64_to_int64 did not take
into account the unsigned conversions
therefore, overflow always occured, and half of the unsigned range
(LONG_MAX .. ULONG_MAX) was broken
introduce roundAndPackInt64NoOverflow and float64_to_int64_no_overflow
for softfloat, that works with unsigned integers as well. note
that this will return zero for nan/inf/oflow/uflow, raising exception
flag
perl is happy now

- provide proper dtoa locks
- use the real strtof implementation
- add strtold, __hdtoa, __hldtoa
- add %a/%A support
- don't lose precision in printf, don't round to double anymore
- implement extended-precision versions of libc functions: fpclassify,
isnan, isinf, signbit, isnormal, isfinite, now that the ieee.h is
fixed
- separate vax versions of strtof, and __hdtoa
- add complex math support. added functions: cacos, casin, catan,
ccos, csin, ctan, cacosh, casinh, catanh, ccosh, csinh, ctanh, cexp,
clog, cabs, cpow, csqrt, carg, cimag, conj, cproj, creal, cacosf,
casinf, catanf, ccosf, csinf, ctanf, cacoshf, casinhf, catanhf,
ccoshf, csinhf, ctanhf, cexpf, clogf, cabsf, cpowf, csqrtf, cargf,
cimagf, conjf, cprojf, crealf
- add fdim, fmax, fmin
- add log2. (adapted implementation e_log.c. could be more acruate
& faster, but it's good enough for now)
- remove wrappers & cruft in libm, supposed to work-around mistakes
in SVID, etc.; use ieee versions. fixes issues in python 2.6 for
djm@
- make _digittoint static
- proper definitions for i386, and amd64 in ieee.h
- sh, powerpc don't really have extended-precision
- add missing definitions for mips64 (quad), m{6,8}k (96-bit) float.h
for LDBL_*
- merge lead to frac for m{6,8}k, for gdtoa to work properly
- add FRAC*BITS & EXT_TO_ARRAY32 definitions in ieee.h, for hdtoa&ldtoa
to use
- add EXT_IMPLICIT_NBIT definition, which indicates implicit
normalization bit
- add regression tests for libc: fpclassify and printf
- arith.h & gd_qnan.h definitions
- update ieee.h: hppa doesn't have quad-precision, hppa64 does
- add missing prototypes to gdtoaimp
- on 64-bit platforms make sure gdtoa doesn't use a long when it
really wants an int
- etc., what i may have forgotten...
- bump libm major, due to removed&changed symbols
- no libc bump, since this is riding on djm's libc major crank from
a day ago
