2014-03-18Retire hp300, mvme68k and mvme88k ports. These ports have no users, keepingMiod Vallat
this hardware alive is becoming increasingly difficult, and I should heed the message sent by the three disks which have died on me over the last few days. Noone sane will mourn these ports anyway. So long, and thanks for the fish.
2014-03-16DDB supports ELF symbols are all archs, and it's always the same as thePhilip Guenther
native size, so eliminate the #defines. ok miod@
2014-03-11lint is gone, and the 'lint' conditional was never in the implementationPhilip Guenther
namespace, so stop changing behavior when it's #defined ok beck@ krw@
2014-01-30Move declaration of struct vm_page_md from <machine/vmparam.h> toMiod Vallat
<machine/pmap.h> where it belongs, and compensate in <uvm/uvm_extern.h> by including <uvm/uvm_pmap.h> before <uvm/uvm_page.h>. Tested on all MACHINE_ARCH but amd64 and i386 (and hppa64).

2013-12-18Provide MI symbol _STACKALIGNBYTESTheo de Raadt
2013-10-17Remove support for a.out and ecoff. We only do elf now.Theo de Raadt
ok miod
2013-08-07We uniformly define size_t to be unsigned long and ssize_t to be long. MakeMark Kettenis
sure that SIZE_MAX and SSIZE_MAX are defined as constants with a matching type on all are architectures. ok millert@, matthew@

2013-06-17m68k kernel memcpy/memmove/bcopy implementation in libkern, remove ovbcopy, ↵Janne Johansson
fix for larger than 128k size copies. Parts from deraadt@, ok (and off-by-one fix) miod@
2013-06-01cleanup and consolidate the spinlock_lock (what a name!) code.Ted Unangst
it's now atomic_lock to better reflect its usage, and librthread now features a new spinlock that's really a ticket lock. thrlseep can handle both types of lock via a flag in the clock arg. (temp back compat hack) remove some old stuff that's accumulated along the way and no longer used. some feedback from dlg, who is concerned with all things ticket lock. (you need to boot a new kernel before installing librthread)
2013-05-21remove unused cpu_lock code (where it is truly unused). it is notTed Unangst
part of the future we have planned. middling ok from a few
2013-04-01Do not expose the trap T_* values to userland, since they invade theTheo de Raadt
namespace a bit much. These are the names for the value encoded in core.c_ucode or siginfo.si_trapno, but userland never looks directly and only cares about the abstract signal code. ok guenther
2013-03-28Add STRONG_ALIAS macros to be used from assembly code in libc andMartynas Venckus
libm. While at it, remove now unused workarounds for lint. Agreed by kettenis@, guenther@, matthew@.
2013-03-28Add __strong_alias macros for all architectures to be able to aliasMartynas Venckus
another symbol without weak attribute. To be used in libc and libm soon. Agreed by kettenis@, guenther@, matthew@.
2013-03-26PGSHIFT and PGOFSET are now contained inside the kernel namespace.Theo de Raadt
2013-03-25Remove the m68k FPU emulator; it was only used by the mac68k port which has beenMiod Vallat
lying in the Attic for quite awhile; none of the remaining m68k-based ports support FPU-less systems; assuming my HP332 cpu board is in working condition, give me memory boards for it to have at least 8MB and a chassis, and I'll consider bringing this code back. But then, the 332 has an FPU socket, and I'd rather write a new glue to use the MI softloat code (bug-free) than try and fix the bugs in this.
2013-03-25PGSHIFT -> PAGE_SHIFTTheo de Raadt
2013-03-25Move SEGSHIFT-related definitions and macros to <m68k/pte_motorola.h>, as theyMiod Vallat
only matter to pmap-related code. Fixes libkvm build on m68k.
2013-03-25ALIGNBYTES/ALIGN/ALIGNED_POINTER can move to the MI file.Theo de Raadt
2013-03-23refactor sys/param.h and machine/param.h. A lot of #ifdef _KERNEL is addedTheo de Raadt
to keep definitions our of user space. The MD files now follow a consistant order -- all namespace intrusion is at the tail can be cleaned up independently. locore, bootblocks, and libkvm still see enough visibility to build. Checked on 90% of platforms...
2013-03-12Fix kernel profiling on MP systems by using per-CPU buffers and teachMartin Pieuchot
kgmon(8) to deal with them, this time without public header changes. Previously various CPUs were iterating over the same global buffer at the same time to modify it and never ended. This diff includes some ideas submited by Thor Simon to NetBSD via miod@. ok deraadt@, mikeb@, haesbaert@
2013-02-12Back out per-CPU kernel profiling, it shouldn't modify a public headerMartin Pieuchot
at this moment.

2013-02-09No longer define the a.out relocation format struct.Miod Vallat
2013-02-06Check for __PIC__, not PIC, as some files in libc will only see the former.Miod Vallat
Fixes the few TEXTREL which crept in libc.so.
2013-02-02Kernel bits for m68k/ELF, mostly from NetBSD. In addition, the `pmod' symbelMiod Vallat
in fpsp has to be renamed due to a clash with other parts of the kernel.
2013-01-16Remove orphaned files.Miod Vallat
2013-01-01Crank NMBCLUSTERS to 4096 to match other 32-bit platforms.Miod Vallat

2012-12-31Allow native ELF binaries (none yet) to run.Miod Vallat
2012-12-02Determine whether we're currently on the alternative signal stackPhilip Guenthe
dynamically, by comparing the stack pointer against the altstack base and size, so that you get the correct answer if you longjmp out of the signal handler, as tested by regress/sys/kern/stackjmp/. Also, fix alt stack handling on vax, where it was completely broken. Testing and corrections by miod@, krw@, tobiasu@, pirofti@
2012-11-21Trivial fixes for labels not followed by statements, which gcc 3 complainsMiod Vallat
about.
2012-08-22sigpid should be of type pid_t (only visable with DEBUG).Okan Demirmen
ok miod@ (who found others to fix as well)
2012-08-07<sys/ktrace.h> is now pulled in via <sys/syscall_mi.h>, so drop it from herePhilip Guenthe
2012-08-07Move the common bits of syscall invocation and return handling intoPhilip Guenthe
an MI file, <sys/syscall_mi.h>, correcting inconsistencies and the handling when copyin() of arguments fails. Tested on i386, amd64, sparc64, and alpha (thanks naddy@) Any issues with other platforms will be fixed in tree. header name from millert@; ok miod@
2012-06-26create new machine/_float.h which is namespace clean. create a newTheo de Raadt
MI float.h which pulls in and defines the values that are needed from there, and repair sys/limits.h so that it defines the values it needs as well (depending on POSIX version, XPG version, etc). guenther has a more exact selection of that coming for limits.h. this also fixes a few mistakes for the vax. reviewed by kettenis and guenther.
2012-04-11The first ktrace record for a newly spawned thread is a returnMike Belopuhov
from a fork syscall done by the parent. Use __tfork, not rfork here to match the ktrace records for the parent (CALL __tfork, RET __tfork). ok guenther
2012-04-10Make the KERN_NPROCS and KERN_MAXPROC sysctl()s and the RLIMIT_NPROC rlimitPhilip Guenthe
count processes instead of threads. New sysctl()s KERN_NTHREADS and KERN_MAXTHREAD count and limit threads. The nprocs and maxproc kernel variables are replaced by nprocess, maxprocess, nthreads, and maxthread. ok tedu@ mikeb@
2011-11-16Make userret() MI. On architectures which jammed stuff into it in theTheo de Raadt
past, pull that code out seperately. ok guenther miod
2011-11-15label_t is the kernel setjmp buffer. It should simply be an array ofTheo de Raadt
the right type, noone will ever fiddle with the internals. discussed with jsing
2011-11-01Drop support for the HP MMU. It was only found on two hp300 systems (modelsMiod Vallat
320 and 350), which have been unsupported since a bunch of release already, because this annoying MMU does not have TT registers (or if it does, it is not documented) and thus went in the way of PMAP_DIRECT for hp300. In other words: remove a bunch of code which was either #ifdef'ed out or had no chance to run in real life.
2011-10-27Specify the TLS variant for each platform.Philip Guenthe
2011-09-28Oops, do not do last minute edits before commit... Make the previous changeMiod Vallat
compile.
2011-09-27Use a pool to allocate pv_entry from, instead of allocating whole pages andMiod Vallat
maintaining our own free lists. No functional change.
