2008-10-23Move the va_copy define to <sys/stdrag.h> making sure it is uniformalyMark Kettenis
protected by __ISO_C_VISIBLE > 1999. With a little help from miod@. ok miod@
2008-10-15make random(9) return per-cpu values (by saving the seed in the cpuinfo),Theo de Raadt
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) ok kettenis drahn
2008-10-10Add empty cpu_unidle() macros for architectures that currently don't doArtur Grabowski
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.
2008-10-10Define MAXCPUS on all architectures.Artur Grabowski
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).
2008-10-09Implement CPU_INFO_UNIT for everyone, not just MP kernels.Artur Grabowski

2008-09-07- replace dtoa w/ David's gdtoa, version 2008-03-15Martynas Venckus
- 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 discussed with / requested by / testing theo, sthen@, djm@, jsg@, merdely@, jsing@, tedu@, brad@, jakemsr@, and others. looks good to millert@ parts of the diff ok kettenis@ this commit does not include: - man page changes

2008-07-24Do not define vax-inspired LOWPAGES and HIGHPAGES anymore, they make noMiod Vallat
sense on m68k. Give USRSTACK its real (HP-UX compatible) value instead of computing it from HIGHPAGES. No functional change.
2008-07-21- add proper double_t and float_t definitions for each archMartynas Venckus
- math.h shouldn't define FLT_EVAL_METHOD, but float.h should (per C99). remove from math.h, and add proper definitions in float.h ok millert@
2008-06-26First pass at removing clauses 3 and 4 from NetBSD licenses.Ray Lai
Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@

2007-11-25libkern, begone. Move to a new mechanism where config(8)'s "file"Theo de Raadt
directive can select between MI and MD versions of these files. At the same time, adjust the boot programs to pick exactly what they need, instead of the 7 or 8 mechanisms previously used. There will be some fallout from this, but testing it all by myself is a ridiculously slow process; it will be finished in-tree. Various developers were very nice and avoided making fun of me when I was gibbering in the corner..

2007-11-09Move splassert_check() from common m68k code to each m68k-based architecture,Miod Vallat
as its implementation may vary accross platforms (and will very soon).

2007-10-14One more cpu_switchto() leftover.Miod Vallat
2007-10-10Make context switching much more MI:Artur Grabowski
- Move the functionality of choosing a process from cpu_switch into a much simpler function: cpu_switchto. Instead of having the locore code walk the run queues, let the MI code choose the process we want to run and only implement the context switching itself in MD code. - Let MD context switching run without worrying about spls or locks. - Instead of having the idle loop implemented with special contexts in MD code, implement one idle proc for each cpu. make the idle loop MI with MD hooks. - Change the proc lists from the old style vax queues to TAILQs. - Change the sleep queue from vax queues to TAILQs. This makes wakeup() go from O(n^2) to O(n) there will be some MD fallout, but it will be fixed shortly. There's also a few cleanups to be done after this. deraadt@, kettenis@ ok

2007-09-10Introduce a md pmap hook, pmap_remove_holes(), which is supposed to markMiod Vallat
the holes a MMU may have from a given vm_map. This will be automagically invoked for newly created vmspaces. On platforms with MMU holes (e.g. sun4, sun4c and vax), this prevents mmap(2) hints which would end up being in the hole to be accepted as valid, causing unexpected signals when the process tries to access the hole (since pmap can not fill the hole anyway). Unfortunately, the logic mmap() uses to pick a valid address for anonymous mappings needs work, as it will only try to find an address higher than the hint, which causes all mmap() with a hint in the hole to fail on vax. This will be improved later.
2007-05-28Move the MSIZE, MCLSHIFT, MCLBYTES and the MCLOFSETThordur I. Bjornsson
mbuf constants from MD param.h to MI param.h. Besides being the same on every arch, things will most probly break if any arch has different values then the others. The NMBCLUSTERS constants needs to be MD though; ok miod@,krw@,claudio@

2007-05-16The world of __HAVEs and __HAVE_NOTs is reducing. All architecturesArtur Grabowski

2007-05-15Remove the MI implementation of mutexes and remove the __HAVE_MUTEXArtur Grabowski
option. Every architecture implements mutexes now.

unconditionnaly.
2007-04-13While splitting flags and pqflags might have been a good idea in theoryArtur Grabowski
to separate locking, on most modern machines this is not enough since operations on short types touch other short types that share the same word in memory. Merge pg_flags and pqflags again and now use atomic operations to change the flags. Also bump wire_count to an int and pg_version might go int as well, just for alignment. tested by many, many. ok miod@
2007-04-10``it's'' -> ``its'' when the grammar gods require this change.Miod Vallat
2007-04-04Mechanically rename the "flags" and "version" fields in struct vm_pageArtur Grabowski
to "pg_flags" and "pg_version", so that they are a bit easier to work with. Whoever uses generic names like this for a popular struct obviously doesn't read much code. Most architectures compile and there are no functionality changes. deraadt@ ok ("if something fails to compile, we fix that by hand")
2007-03-21Real atomic_{set,clear}bits_int implementation, no performance hit on 060Miod Vallat
unless used on non-aligned data; ok deraadt@
2007-03-04Oops, bring back pmap_collect1() and the check for pmap_kernel() inMiod Vallat
pmap_collect() as we do an explicit pmap_collect(pmap_kernel()) in dire memory situations.

2007-02-17If we __HAVE_PMAP_DIRECT, handle these mappings in pmap_extract().Miod Vallat
2007-02-17In pmap_collect():Miod Vallat
- do not bother checking for pmap_kernel() and operating on it, as pmap_collect() will not be invoked for P_SYSTEM process. - preserve wired pages while purging.
2007-02-06Add machine/atomic.h to all architectures and define two operationsArtur Grabowski
right now that are supposed to be atomic with respect to interrupts and SMP: atomic_setbits_int and atomic_clearbits_int. All architectures other than i386 and amd64 get dummy implementations since at first we'll be replacing operations that are done with "a |= bit" and "a &= ~bit" today. More proper implementations will follow kettenis@, miod@ ok
2007-02-05Oops, forgot to commit these files when adding md mutex code; spotted by nick@Miod Vallat
2007-02-03Simple single-processor mutex implementation, simpler than the MI code byMiod Vallat
use of MD spl code bowels. No functional change.
2007-01-28optimize m68k writeback():Miod Vallat
- it can really only be invoked from trap(), not from other userret() callers, so it is safe to hardcode its docachepush parameter to 1. - use pmap_kenter_pa()/pmap_kremove() for the temporary mapping instead of pmap_enter()/pmap_remove(). optimize m68k userret(): - define PROC_PC for m68k systems. - only check want_resched when processing T_ASTFLT traps. - provide two version of userret(), one which will also invoke writeback() on 68040 if required, which is only invoked from trap(), and regular userret(). This speeds up system call returns.
