2011-06-06Fix whitespace and use #ifdef TRAPDEBUG instead of #if 0.Joel Sing
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
2011-05-30Remove 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@.
2011-05-24On OpenBSD, we've always attached scsibus(4) to umass(4), even forMatthew Dempsky
ATAPI devices. atapiscsi(4) is only for handling ATAPI devices on an ATA bus, so umass(4) shouldn't care about it. ok krw@, dlg@; no objections from deraadt@
2011-05-21Add pci_intr_map_msi() stub.Mark Kettenis
2011-05-12Get rid of the biomask printf here as well. Suggested by mikeb@Mark Kettenis
2011-05-07So long, uvm_pglist.hOwain Ainsworth
This header defined three thing. two of which are unused throughout the tree, the final one was the definition of the pagq head type, move that to uvm_page.h and nuke the header ok thib@. Thanks to krw@ for testing the hppa build for me.
2011-05-05Adjust comments on the statements in the various ITLB handlers that make sureMark Kettenis
the gateway pages is mapped as a public page. The origional comment didn't really explain what was happening here.
2011-05-02Cope with userland mappings of unmanaged pages (i.e. device memory beingMiod Vallat
mmap'ed), by properly making these mappings uncached, and correctly accounting their removal to not get stuck with leftover pte pages. While there, change a can't happen infinite loop in pmap_destroy() into a KASSERT. feedback and ok kettenis@
2011-05-01Fix counting of interrupts for devices that attach to elroy(4). SharedMark Kettenis
interrupts would be counted double, once for the interrupting device and once for the device at the head of the chain. The handlers would run properly though. Avoid this by giving each device its own interrupt counter instead of using the counter provided by the generic interrupt handling code for the head of the chain.
2011-04-28Expose pmap_prefer parameters.Ariane van der Steldt
This will enable intelligent decisions with future uvm_map.

2011-04-25Move .rodata 512KB further once more.Mark Kettenis
ok deraadt@
2011-04-23Stop calling shared interrupt handlers as soon as one of them return 1Mark Kettenis
(positive interrupt was for me), like we do on other architectures. This is done here, at the elroy(4) driver level, since this is where shared PCI interrupts are handled. We could do something similar for dino(4) but this optimization is probably not very relevant there. ok deraadt@
2011-04-21fenv for hppaMartynas Venckus
2011-04-20Back out r1.10 of mutex.c as this breaks serial on hppa (at least for MP).Joel Sing
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
2011-04-17Tweak the behaviour of boot(8) on hppa. Normal boots now will give you aMark Kettenis
chance to interrupt the boot procedure before booting the default kernel, just like (most) of our other hardware platforms. Interactive boots, where you interrupt the firmware boot procedure and answer "Y" to the "Interact with IPL?" question will now wait for human intervention at the boot> prompt (without a timeout). Should reduce frustration when trying to boot an alternative kernel. ok deraadt@, miod@, jsing@, todd@
2011-04-16Initialize %cr30 for proc0 with the address of proc0fpstate. Shouldn't reallyMark Kettenis
matter, since we shouldn't be using the FPU inside the kernel, but we need to initialize %cr30 with something, and this is more consistent than using the address of the pcb.
2011-04-16_LOCORE is already definedTheo de Raadt
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.
2011-04-10'kernel libraries' always get in the way of the build process. TeachTheo de Raadt
autoconf how to find the spmath files.
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@
2011-03-24Process interrupts in priority order. Joint work with jsing@.Mark Kettenis
ok jsing@
2011-03-23Normalize sentinel. Use _MACHINE_*_H_ and _<ARCH>_*_H_ properly and consitently.Paul Irofti
Discussed and okay drahn@. Okay 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
2011-03-11Use _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@
2011-02-17Disable sbt and ubt devices. The bluetooth code will sometimes sleep whileMiod Vallat
holding locks, this is not allowed, and nobody has stepped up to fix this, so better not lure people into using bluetooth devices.

resetting the clock when we don't need to. Found out with booting hppa64 kernels, and the problem also exists on hppa when booting with '-a' and hitting 'exit' when asked for the root filesystem. help & ok jsing@ also ok kettenis@ (who suggested naming the variable like amd64/i386 to prevent creating yet another variant of this code)
