2008-11-24die die dieTheo de Raadt
2008-11-24In pmap_write_protect() clear and set the protection bits atomically andKurt Miller
leave the rest alone. Also don't read *spte twice and compare results. feedback drahn@ okay art@ weingart@
2008-11-24In pmap_clear_attrs() use i386_atomic_clearbits_l() to only clear theKurt Miller
bits necessary. Also move up the pmap_map_ptes() call to before the diagnostic check. okay art@, weingart@

2008-11-22Move the drm drivers over from:Owain Ainsworth
vga1 at pci0 inteldrm0 at vga1 to vga1 at pci0 inteldrm0 at vga1 drm0 at inteldrm0 i.e. a similar scheme to audio(4) where the interface attaches on top of the wildly different drivers. This helps to clean up the code a lot (more is coming) and help me start to move drm to being essentially bus independent, which will help in the future.
2008-11-22Allow wired memory to be accounted on i386. This automatically changesMike Belopuhov
the policy for the mlock(2) on this architecture: all users are allowed to call mlock, while the limit is imposed by the current RLIMIT_MEMLOCK value. "makes sense" art, ok hshoexer (who was running with the same change for about 10 months).
2008-11-22The last parts of cpu_unidle. i386, amd64 and sparc64Artur Grabowski
In short, make cpu_unidle do what signotify used to do and make signotify use cpu_unidle. Also, include a cpu_unidle in need_resched, it won't change much right now but will be needed in the future.
2008-11-22same change as for amd64. Move bus_space_* functions from inlines andOwain Ainsworth
defines into real functions. since machdep.c is cluttered as it is move them into bus_space.c (like amd64). a later commit will move the stuff from machdep across too. since machdep.c is cluttered as it is move them into bus_space.c (like amd64). a later commit will move the stuff from machdep across too. some shrinkage stats: GENERIC.MP 209.66kb RAMDISK 50.84kb RAMDISKB 50.04kb RAMDISC 36.28kb RAMDISK_CD 168.03kb don't fill it up all at once! claudio found no network performance hit. toby thought the code went looked alright. art@ ok.
2008-11-21add forgotten ioctls. allows writing to extra counters found on amd cpus.Mike Belopuhov
2008-11-14Garbage collect the LDT segments, and simply use the GDT segments.Tobias Weingartner
The beginning of i386 segment review/cleanup. Tested by various people.

okay weingart@ art@
2008-11-09Rework that way that agp attaches.Owain Ainsworth
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.

2008-10-28Try to use ACPI a little bit harder. Skip it only if ncpu < 2 and theTheo de Raadt
SMBIOS version is < 2.4. This lets 40-series thinkpads continue to use apm. worked on with kettenis
2008-10-25audio(9) says low level drivers are allowed to change the requestedJacob Meuser
values of the audio_params structure during AUDIO_SETINFO if the hardware cannot be set to exactly the requested mode. some drivers do this sometimes. others always return EINVAL if there isn't an exact match. be more consistent. only return EINVAL if an absurd parameter was requested, otherwise return a supported set of parameters, as close as possible to what was requested. with/ok ratchov@

2008-10-19Shuffle MULTIPROCESSOR ifdef's around to allow code that deals withBrad Smith
the CPU roles to compile on !MULTIPROCESSOR kernels and make the top part of cpu_attach() which deals with processor setup depending on the CPU role look much closer to the equivalent code for amd64. ok kettenis@
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
2008-10-15inteldrm and radeondrm are pretty stable by this point, so enable them on amd64Owain Ainsworth
and i386. deraadt got sick of me wussing out over this.
2008-10-10Use the MI random() for all cases; no need for a MD version since itTheo de Raadt
has never been performance sensitive. Running on all platforms, discussed with millert and kettenis, ok toby

Really just the low-hanging fruit of (hopefully) forthcoming timeout conversions. ok art@, krw@
2008-09-08delete a few more things. hoping someone shows up who is upset by this,Theo de Raadt
and puts some backpressure on this process. come on, someone get mad... and do something about it!
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
2008-09-01Avoid #pragma pack(1) and unify everything towards using __packed.Theo de Raadt
This requires that structures defined within __packed structures must independently request that they themselves become __packed, too. worked on with toby CVS: ----------------------------------------------------------------------
2008-08-16bios_dev -> ba_name and bios_apmp -> ba_apmp in DPRINTF statements.Kenneth R Westerback
i386 kernels compile with BIOS_DEBUG again. Spotted by Mathias Schmocker.
2008-08-13Disable the fantastics mis-feature on some newer Turion CPUs called C1E.Artur Grabowski
This "power saving" disables the apic when both cpu cores hit the hlt instruction which kills our timer. From FreeBSD. (poked by kettenis)
2008-08-12Fix multiple addition error recently introduced for when extended partitionsTheo de Raadt
are just before an OpenBSD partition in a MBR; done with kettenis & otto ok reyk
2008-08-08Admit b_blkno means block number; a block is DEV_BSIZE (a.k.a.Kenneth R Westerback
512) bytes; ffs is inextricably tied to using b_blkno and disklabel always uses sectorsize units. Thus use DEV_BSIZE units for all fields describing ffs filesystems and convert to/from sectors where required. This enables the creation and use of ffs filesystems on non-512 byte sectorsize devices. This diff allows i386 and sgi (the two test platforms) to find disklabels that are not on a sectorsize boundary. Same change to further archs coming. This is a no-op on 512-byte sectorsize devices. This work triggered by jsing@'s need to create ffs filesystems on sgi cdroms so we can create cdrom install media for sgi. sgi testing by jsing@ ok jsing@ pedro@ "looks sane" beck@ weingart@
2008-08-04fix extended partition support by handling chained EBRs correctlyReyk Floeter
(using a recursion limit). now OpenBSD can be installed in a subsequent DOS/Linux-compatible extended partition. ok krw@ deraadt@
2008-08-02compile inteldrm and radeondrm in GENERIC by default, but disabled.Owain Ainsworth
This will let them get some more testing. Re-order things a little while i'm here. prompted by and ok deraadt@.
