2012-08-22Convert cpp | as rules in bsd.lib.mk and lib/libc/sys/Makefile.inc to pure ccPascal Stumpf
invocations. This allows us to use the compiler builtin define __PIC__ to check for PIC/PIEness rather than passing -DPIC. Simplifies PIE work a lot. ok matthew@, conceptually ok kurt@
2012-08-21For interrupts that get established before we attach the interrupt controller,Mark Kettenis
store the type of the interrupt (level, edge). ok miod@, mpi@
2012-06-26create new machine/_float.h which is namespace clean. create a newTheo de Raadt
MI float.h which pulls in and defines the values that are needed from there, and repair sys/limits.h so that it defines the values it needs as well (depending on POSIX version, XPG version, etc). guenther has a more exact selection of that coming for limits.h. this also fixes a few mistakes for the vax. reviewed by kettenis and guenther.
2011-11-15label_t is the kernel setjmp buffer. It should simply be an array ofTheo de Raadt
the right type, noone will ever fiddle with the internals. discussed with jsing
2011-11-09Add magic to use %r2 as the userland thread register.Mark Kettenis
ok guenther@
2011-10-27Specify the TLS variant for each platform.Philip Guenthe
2011-09-08Provide namespace-safe alignment macros in <machine/_types.h>, withPhilip Guenthe
compat names kept in <machine/param.h>. In <sys/socket.h>, pull in <sys/_types.h> instead of the namespace polluting <machine/param.h> and completely eliminate __CMSG_ALIGN, replaced by _ALIGN ok deraadt@
2011-09-08Make the INT_FAST*_{MIN,MAX} macros match the types they're defined to.Philip Guenthe
Since the underlying types of the int_fast types are set by machine/_types.h, put internal macros in that same file and define the exposed INT_FAST*_{MIN,MAX} macros from those. ok millert@, kettenis@
2011-08-29Return of the long missing powerpc interrupt rewrite. Was working forDale Rahn
several weeks before release on macppc, socppc bugs just fixed.
2011-08-29Only provide FLT_EVAL_METHOD for C99. Add missing DECIMAL_DIG for C99.Mark Kettenis
ok guenther@
2011-08-22move powerpc to non-__STRICT_ALIGNMENT, as it always was. EssentiallyTheo de Raadt
__STRICT_ALIGNMENT is talking about accessing of integer types; it does not cover doubles or floats or other things ok miod kettenis
2011-08-22mark setfault() with __returns_twiceTheo de Raadt
ok kettenis drahn
2011-05-25Also enclose variable names with external linkage in __BEGIN_DECLS.Martynas Venckus
Doesn't matter much since C++ ABI used by GCC doesn't mangle variable names; however technically is required by Section 7.5 of the C++ spec. Discussed with/OK guenther@, matthew@.

2011-04-25fenv for powerpcMartynas Venckus
2011-04-07Make sure the ALIGN() macro uses u_long on all platforms for consistency, andMiod Vallat
update the comment block accordingly.
2011-03-23Normalize sentinel. Use _MACHINE_*_H_ and _<ARCH>_*_H_ properly and consitently.Paul Irofti
Discussed and okay drahn@. Okay deraadt@.
2011-03-11Use _MACHINE_ENDIAN_H_ for this is The Right Thing To Do.Paul Irofti
Okay guenther@, millert@.
2011-01-08rename imask[] to cpu_imask[] to because imask is too loud as far asTheo de Raadt
kernel namespace ok miod
2010-12-26Kill pmap_phys_address(), and force every driver's mmap() routine to returnMiod Vallat
a physical address [more precisely, something suitable to pass to pmap_enter()'sphysical address argument]. This allows MI drivers to implement mmap() routines without having to know about the pmap_phys_address() implementation and #ifdef obfuscation.
2010-12-21Convert netisr to a normal soft interrupt instead of hanving MD codeClaudio Jeker
for it. This makes the netisr a real C function which will help further development. No noticable performance change on i386 and amd64. With input from kettenis@ and miod@ additional OKs mikeb@ and henning@
2010-11-27Remove ddb single-step load and store counters. Most platforms do notMiod Vallat
implement them, and they are of questionable usefulness.
2010-11-18Declare pmap_proc_iflush() in <uvm/uvm_pmap.h> unless <machine/pmap.h>Miod Vallat
provides an inline version of it.
2010-10-01Provide a WEAK_ALIAS macro in <machine/asm.h> for the few platformsPhilip Guenthe
that didn't already have one, and then immediately use it in libc's SYS.h ok miod@
2010-09-28Implement a per-cpu held mutex counter if DIAGNOSTIC on all non-x86 platforms,Miod Vallat
to complete matthew@'s commit of a few days ago, and drop __HAVE_CPU_MUTEX_LEVEL define. With help from, and ok deraadt@.
2010-06-27Add the TPOFF* and DTP{MOD,OFF}* definitions that ld.so will need forPhilip Guenthe
doing thread-local storage and fix a typo in one that was already defined. ok kettenis@ drahn@
2010-04-23Make sure IPL_SCHED is always defined by MD headers, instead of having a MIMiod Vallat
fallback definition in <sys/sched.h>, so that there is no hidden include ordering requirement between <machine/intr.h> and <sys/sched.h>. ok deraadt@ tedu@
2009-11-27Move MB_LEN_MAX into the machine-independent sys/limits.h header,Philip Guenthe
rather than defining it separately for each architecture. Also set it to 4, to accommodate for future UTF-8 support (rfc3629). Diff by stsp, committing to catch the libc major bump ok kettenis@, guenther@
2009-11-04Get rid of __HAVE_GENERIC_SOFT_INTERRUPTS now that all our platforms support it.Mark Kettenis

chips, like MPC8xxx family. ok kettenis@
2009-08-22Constify the what/name parameter of pci_intr_establish().Michael Knudsen
Tested by myself, sthen, oga, kettenis, and jasper. Input from sthen and jasper. ok kettenis (Manpage follows shortly.)
2009-06-09backout interrupt diff until it the next round of fixesTheo de Raadt
2009-06-02Reintroduce the macppc interrupt subsystem rewrite. Several bugs haveDale Rahn
been found and corrected.
2009-03-26Remove cpu_wait(). It's original use was to be called from the reaper soOwain Ainsworth
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. ok miod@
2009-03-15Let CPU_INFO_UNIT() be used before cpu0 attaches, and make sureMiod Vallat
CPU_INFO_FOREACH() only covers attached cpus. With drahn@, ok kettenis@
2009-03-15Introduce splsoftassert(), similar to splassert() but for soft interruptMiod Vallat
levels. This will allow for platforms where soft interrupt levels do not map to real hardware interrupt levels to have soft ipl values overlapping hard ipl values without breaking spl asserts.

ok drahn@
2008-11-21back out the new interrupt subsystem because some little bug still lurks in ↵Theo de Raadt

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
2008-10-10Define 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).
2008-09-19miod pointed out that some items were multiply defined (patched intoDale Rahn
existance too many times).
2008-09-18Redesign of the powerpc interrupt architecture, use true levels intead ofDale Rahn
blocking specific interrupts. Needs signficant testing to prove that one remaining elusive bug has been squashed.
2008-09-16SMP ddb support, with some feedback from kettenis.Dale Rahn
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
2008-07-21- 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@
2008-07-18Add a macro that clears the want_resched flag that need_resched sets.Artur Grabowski
Right now when mi_switch picks up the same proc, we didn't clear the flag which would mean that every time we service an AST we would attempt a context switch. For some architectures, amd64 being probably the most extreme, that meant attempting to context switch for every trap and interrupt. Now we clear_resched explicitly after every context switch, even if it didn't do anything. Which also allows us to remove some more code in cpu_switchto (not done yet). miod@ ok
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@
