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
2008-10-15Second pass of simple timeout_add -> timeout_add_sec conversionsBret Lambert
This should take care of the simpler ones (i.e., timeout values of integer multiples of hz). ok krw@, art@
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

2008-10-01Be more agressive in flusing the cache. In addition to flushing theMark Kettenis
instruction cache, also purge TLB entries. The PA-RISC 2.0 architecture says that cache lines may be moved in when a translation exists even if no access is done. This might have been hurting us badly since we create illegal aliases in pmap_zero_page() and pmap_copy_page(). Probably not perfect yet, and perhaps a bit of a sledgehammer, but it makes PA-RISC 2.0 machines stable again.
2008-09-30Do not perform cache operations in vmapbuf(), pmap is supposed to do themMiod Vallat
for us if needed. ok art@ kettenis@
2008-09-14Use one block mapping to map kernel text up to 4MB and another one for theMark Kettenis

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
2008-09-06Fix comment to catch up with HPPA_PGALIAS change.Mark Kettenis
2008-08-24Correct eisa i/o ports layout structure, this has probably been brokenMiod Vallat
when switching from gcc 2.95, if not forever.
2008-08-22Set PIE address range to avoid or minimize mmap pressure due to limitedKurt Miller
address space. The space between PAGE_SIZE and the non-pie fixed link address creates no mmap pressure so use that space for PIE. However on hppa the non-pie fixed link address is PAGE_SIZE so just use a small range for PIE to minimize mmap pressure. okay miod@
2008-08-18Add stge(4) and gentbi(4).Mark Kettenis
2008-07-28No longer clear ci_want_resched within cpu_switchto(), now that it's doneMiod Vallat
in the MI code.
2008-07-23Do not rely on an <ichc>invisible cast</ichc> to return failure inMiod Vallat
dino_intr_map(); rather than adding the missing cast, make the intent of the code clearer by explicitenly testing for PCI_INTERRUPT_LINE being ff. While there, enable the out-of-extent-range checks in dino_memmap() and dino_memalloc() even if no option DEBUG, but return failure instead of panicing. discussed with and ok kettenis@ marco@
2008-07-23So it turns outthe HP engineers changed the PA-RISC 2.0 architectureMark Kettenis
after it was published. In particular, they changed the maximum cache aliasing boundary from 1MB to 16MB. It turns that on the PA-8700 the aliasing boundary is actually 4MB (reported as such by the firmware at least). There are some comments in the Linux code that suggest that HP never actually built PA-RISC CPUs with an 8MB or 16MB aliasing boundary. So raise the aliasing boundary to 4MB. This fixes the weird ps(1) problem where it didn't print its own arguments correctly.
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
2008-07-16Implement pckbc_xt_translation() in gsckbc. Thus, we can attach pckbd instead ofMiod Vallat
gsckbd; the former will cause a proper translation page to be selected by the keyboard. Because of this, we no longer depend on the page the keyboard is left in by the PDC (page 2 for all machines but the PrecisionBook, which is in page 3), and there is no longer any need to use separate keyboard maps.

2008-06-27Clear swap encryption keys before dumping a kernel image.Miod Vallat
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@
2008-06-25Move .rodata 512KB further, since kernels will soon reach the address .rodataMiod Vallat
is currently linked at. This should eventually be replaced with a proper alignment construct in the ld script, but it's too hot and too late to do this correctly and I need a kernel that links (containing stuff to reach a cvs tree near you reasonably soon).
2008-06-14defininig NATIVE_EXEC_ELF is mandatory on ELF platforms.Miod Vallat

ok thib beck art
2008-06-11back out biomem diff since it is not right yet. Doing very largeTheo de Raadt
file copies to nfsv2 causes the system to eventually peg the console. On the console ^T indicates that the load is increasing rapidly, ddb indicates many calls to getbuf, there is some very slow nfs traffic making none (or extremely slow) progress. Eventually some machines seize up entirely.
2008-06-10Fix buffer cache pending read statistics by ensuring we can identifyBob Beck
biowait() reads that do *not* come from the buffer cache - we use the B_RAW flag to identify these at art's suggestion - since it makes sense and the flag was not being used. this just flags all these buffers with B_RAW - biodone already ignores returned buffers marked B_RAW. ok art@

2008-04-19Change ELF loader to use the LMA as the load address for theTobias Weingartner
various segments. Hopefully this will help remove various hacks in the boot loader in the future. This should have no effect on most architectures (as we tend to have LMA == VMA). ok drahn@, soft ok's various others.
