2011-06-05Move the bufcachepercent setting code to MI locations -- set it to 42%Theo de Raadt
for now; that is unlikely to hit some of the remaining starvation bugs. Repair the bufpages calculation too; i386 was doing it ahead of time (incorrectly) and then re-calculating it. ok thib
2011-06-05Drop kernel support for the useless DIOCWLABEL ioctl and prune a lotMatthew Dempsky
of silly flag twiddling code in various disk drivers. ok deraadt@, miod@ N.B., users will need a -current disklabel(8) to be able to write new disklabels to disk now.
2011-06-03Get rid of the wlabel argument to bounds_check_with_label(). It'sMatthew Dempsky
never done anything in OpenBSD and just clutters disk drivers with silly flag handling. More cleanup to follow. ok deraadt@, millert@; no objections krw@
2011-05-31The various cleanups of the last few years have fixed pnozz(4) accelerationMiod Vallat
code operation in 640x480 mode (very likely p9100.c r1.47), so enable it again by default. Verified to work on a SPARCbook 3XP (with a 640x480 LCD panel), thanks to Thibaud Bordier.
2011-05-30Remove the freelist member from vm_physsegOwain Ainsworth
The new world order of pmemrange makes this data completely redundant (being dealt with by the pmemrange constraints instead). Remove all code that messes with the freelist. While touching every caller of uvm_page_physload() anyway, add the flags argument to all callers (all but one is 0 and that one already used PHYSLOAD_DEVICE) and remove the macro magic to allow callers to continue without it. Should shrink the code a bit, as well. matthew@ pointed out some mistakes i'd made. ``freelist death, I like. Ok.' ariane@ `I agree with the general direction, go ahead and i'll fix any fallout shortly'' miod@ (68k 88k and vax i could not check would build)
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@.
2011-04-30Plug holes in cdevsw[] to make vscsi, diskmap and pppx entries match theMiod Vallat
numbers in comments and the MAKEDEV majors.
2011-04-28Expose pmap prefer parameters.Ariane van der Steldt
Enables future uvm_map code to make intelligent decisions. No functional change.
2011-04-28fenv improvements and cleanupsMartynas Venckus
2011-04-26MMU address space holes are at a fixed position (ofcourse).Ariane van der Steldt
Therefore set UVM_FLAG_FIXED and enforce this. ok oga@
2011-04-25fenv for sparc; mostly cloned from sparc64Martynas Venckus
2011-04-22Turning on SCSIDEBUG (for debugging other drivers, of course) shouldTheo de Raadt
not make these drivers spew millions of lines of output. spotted as missing by miod
2011-04-21Revert the ``remove the `skip splraise/splx for IPL_NONE mutexes' optimization''Miod Vallat
change. It seems to have unexpected side effects, especially on MP systems, and drahn@ disagrees with the way this change has been done and think there is a better way to solve the original problem of msleep() fiddling with mutex internals.
2011-04-18Revert the sigacts diff: NFS can apparently retain pointers to processesPhilip Guenthe
until they're zombies and then send them signals (for intr mounts). Until that is untangled, the sigacts change is unsafe. sthen@ was the victim for this one
2011-04-16Fix kernel build after guenther@'s signal changes.Miod Vallat
2011-04-16Use 'CLR(<buf>->b_flags, B_READ | B_WRITE | B_DONE)' regardless ofKenneth R Westerback
what the previous IO was. Less chance of copy and paste errors. Suggested by miod@.
2011-04-15In days of yore one could arbitrarily whack buffer flags. Those daysKenneth R Westerback
are past. Use CLR() and SET() to modify necessary flags while leaving the flags used by the buffer cache in peace. Should make bufcache code much less confused about the state of the bufs used in reading/writing disklabels. Other such flag abuses no doubt await a visit. Errors in original diff found by miod@. ok beck@ deraadt@
2011-04-15Correct the sharing of the signal handling state: stuff that shouldPhilip Guenthe
be shared (p_sigignore, p_sigcatch, P_NOCLDSTOP, P_NOCLDWAIT) moves to struct sigacts, wihle stuff that should be per rthread (ps_oldmask, SAS_OLDMASK, ps_sigstk) moves to struct proc. Treat the coredumping state bits (ps_sig, ps_code, ps_type, ps_sigval) as per-rthread until our locking around coredumping is better. Oh, and remove the old SunOS-compat ps_usertramp member. "I like the sound of this" tedu@
2011-04-15Convert the kernel Makefiles to autogenerate dependencies during compilationPhilip Guenthe
using the -MD option to cc, with -MP, -MT, and -MF where needed, converting "make depend" to a no-op. This increases parallelism for those using "make -j" and keeps the dependencies up to date with each compilation automatically. sparc and vax users will need to rebuild gcc with support for the -M[PTF] options before config'ing with this diff.
2011-04-14Sprinkle prototypes, kill unused locals, and stop contributing to globalMiod Vallat
warning.
2011-04-07Make sure the ALIGN() macro uses u_long on all platforms for consistency, andMiod Vallat
update the comment block accordingly.
2011-04-07Do not use NULL in integer comparisons. No functional change.Miod Vallat
ok matthew@ tedu@, also eyeballed by at least krw@ oga@ kettenis@ jsg@
2011-04-06The various read*label() have stopped returning error strings for quiteMiod Vallat
some time, and return errnos instead. Fix or remove out-of-date comments mentioning the error strings, and make their callers check the return value against zero, not NULL.
2011-04-03Remove the `skip splraise/splx for IPL_NONE mutexes' optimizations. It is notMiod Vallat
always gaining anything, and msleep() implementation depends upon mtx_leave() invoking splx().
2011-04-03Move PPWAIT flag from struct proc to process, so that rthreads inPhilip Guenthe
a vforked child behave correctly. Have the parent in a vfork() wait on a (different) flag in *its* process instead of the child to prevent a possible use-after-free. When ktracing the child return from a fork, call it rfork if an rthread was created. ok blambert@
2011-03-23Normalize sentinel. Use _MACHINE_*_H_ and _<ARCH>_*_H_ properly and consitently.Paul Irofti
Discussed and okay drahn@. Okay deraadt@.
2011-03-18Add some delay between a successful keyboard reset sequence and a keyboardMiod Vallat
layout inquiry, as some PS/2 converters (at least the Starview SV 125) need it to behave correctly. Found the hard way and researched by Mike Malopolski, thanks!
2011-03-18Fix obj directory probing to support cross compiling.Matthew Dempsky
"Go for it" deraadt@
2011-03-13Change daddr_t to daddr32_t. The bootblocks on our architectures onlyTheo de Raadt
do 32-bit block spanning. If later on we get some that can/should do 64-bit, that can be done now using daddr64_t (but of course, we are taking this step to finalize the daddr_t 64-bit conversion). ok miod krw
2011-03-12incorrect parameters to warn()Theo de Raadt
2011-03-11Use _MACHINE_ENDIAN_H_ for this is The Right Thing To Do.Paul Irofti
Okay guenther@, millert@.
2011-02-26Force the DUID cache used to generate hw.disknames to be updatedKenneth R Westerback
after every disklabel read or write. This keeps the DUID cache more in sync with the physical world. De-syncing noted by drahn@ while zapping disklabels with dd. ok jsing@ deraadt@
2011-01-14- use nitems()Jasper Lievisse Adriaanse
"doesn't hurt" deraadt@
2010-12-30If genassym fails, sort on the pipeline will indicate no error resultingTheo de Raadt
in some grief. Split this out. From Vladimir Kirillov
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.
2010-12-26Clean up how we print the sbus(4) clock speed. Purely cosmetic.Mark Kettenis
ok miod@, deraadt@
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@
2010-12-15oops, i forgot to check in the BRKSIZ define in uvm, but deraadt thinksTed Unangst
its better as a per arch MD define anyway. all default to MAXDSIZ as before.
2010-12-14There is no "struct filesystem"; uncovered by gcc4.Mark Kettenis
ok miod@
2010-12-06Change the signature of PMAP_PREFER from void PMAP_PREFER(..., vaddr_t *) toMiod Vallat
vaddr_t PMAP_PREFER(..., vaddr_t). This allows better compiler optimization when the function is inlined, and avoids accessing memory on architectures when we can pass function arguments in registers.
2010-12-06- use consistent 'include' rules without a full relative path.Jasper Lievisse Adriaanse
tested on a GENERIC config from all arches. ok deraadt@ miod@
2010-12-02After the most recent change, make it possible to make -j again. TheTheo de Raadt
early MD and late MI files must be split up so that vers.o can sneak between. Issue spotted by bluhm, repair discussed with miod
2010-12-02move vers.o to before the other objects, so that it is not linked last.Theo de Raadt
having it linked last is bad (on at least i386 and amd64) because the lapic is mapped over the start of the data segment -- savecore(8) then reads the version string for a fixed buffer space, and reads into the lapic area causing unintended side-effects (at least on Intel X5570 and X5680) found by pedro, discussed with kettenis and mpf and miod
2010-11-27Remove ddb single-step load and store counters. Most platforms do notMiod Vallat
implement them, and they are of questionable usefulness.
2010-11-27Misaligned load/store recovery code in the kernel, enabled by T_FIXALIGNMiod Vallat
userland traps on a per-process basis, were necessary for *some* SunOS binaries on sparc, which had to compiled with explicit misaligned access code generation (i.e. for vendors to release a working SunOS/sparc version of their code until they could fix their bogus code). There is no reason to keep this code on sparc64, and now that we don't provide COMPAT_SUNOS anymore, there is no reason to keep this code on sparc. ok kettenis@
2010-11-27Make sure kcopy() returns EFAULT instead of -1 upon failure on vax, andMiod Vallat
fix outdated comments suggesting kcopy() will return -1.
2010-11-19Sync MAKEDEV against conf.c, and both against GENERIC.Miod Vallat
2010-11-19add pseudo-device hotplug.Miod Vallat
2010-11-19gapz@dud-t . org noted that sparc64 installboot crashes if the bootblock isTheo de Raadt
zero-sized. Apply similar fixes to installboot for other architectures.
