2008-10-23a better fix for the "uvm_km thread runs out of memory" problem.Ted Unangst
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. ok deraadt

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).
2008-10-07unbreak ieeefp emulation code wrt converting double to unsignedMartynas Venckus
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 looked over by miod@ tested by naddy@, and by me on nick@'s alpha

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

2008-07-25Improve eisa bus probe by deciding the number of logical eisa slots fromMiod Vallat
the motherboard eisa id, instead of using a ``one size fits all'' value which is too large on more than half the eisa-capable alpha designs. The id -> slot # logic is based on the alpha ECU configuration files, so we should not perform worse than ECU itself (and see all slots ECU sees too).

plugged to the bottom 4 PCI slots of AlphaServer 1000A (attaching to pci1 behind a ppb) to get interrupts. No regressions on AlphaServer 800 (which do not have these extra slots).
2008-07-19Add code to walk the eisa configuration, from NetBSD. This configurationMiod Vallat
is not used yet, but this seems to ``warm up'' the eisa chips so that accesses to the eisa bus later do not cause machine checks.

instead of only the starting address. From NetBSD.
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
2008-07-16Add a new parameter to pckbc_cnattach(): flags to put in the pckbc bowels.Miod Vallat
For now, only one such flag is defined, PCKBC_CANT_TRANSLATE. It hints pckbc that the device does not behave correctly to the ``set translation'' commands. Set this flag if we are running on a Tadpole Ultrabook machine, which needs it. This makes the built-in keyboard work correctly on this laptop (with the help of the software translation pckbd diff). tested & ok kettenis@

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@

2008-06-11back 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@
