Create a new header lwp_private.h to contain _lwp_getprivate_fast,
_lwp_gettcb_fast, _lwp_settcb and remove them from mcontext.h, so that:
1. we don't need special hacks to hide them
2. we can include <lwp.h> where needed to get the necessary prototypes
without redefining them locally.

Remove the kernel PMC code. Sent yesterday on tech-kern@.

This change:

* Removes "options PERFCTRS", the associated includes, and the associated
ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
good.

* Removes the PMC code of ARM XSCALE.

* Removes all the pmc.h files. They were all empty, except for ARM XSCALE.

* Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
definitions are put in sysarch.h.

* Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
netbsd32 and rump.

* Removes the pmc_evid_t and pmc_ctr_t types.

* Removes all the associated man pages. The sets are marked as obsolete.

Implement pmc(9) -- An interface to hardware performance monitoring
counters. These counters do not exist on all CPUs, but where they
do exist, can be used for counting events such as dcache misses that
would otherwise be difficult or impossible to instrument by code

pmc(9) is meant to be a general interface. Initially, the Intel XScale
counters are the only ones supported.

Require that each each MACHINE/MACHINE_ARCH supply a lock.h. This file
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED. These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case). Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.

These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.

branches: 1.1.4;
Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

Replace ansi.h with a version that just does #include <mips/ansi.h>.

Add a prototype for generic_intr_establish(), the bus-independent

the NetBSD-1.1 convention. Change the mainbus `struct confargs'
and the "generic" interrupt-establish method, used by devices that
appear on both a kn01 and TC decstations, to match.

Change the macros in autconf.h accordingly.

Re-write Decstation turbochannel autoconfiguration code to use the machine-
independent TC support in sys/dev/tc/tc.c and sys/dev/tc/tcvar.h:
* Change the tc autoconfiguration tables to use a struct tc_attach_args
instead of the ad-hoc structure.
* Change all pmax device drivers to use a `struct confargs' that's
assignment-compatible with sys/dev/tc/tcvar.h `struct tcdev_attach_args'.
Devices that can be present on a TC or as ioctl asic/mainbus builtins
use the same `struct confargs'.
* Eliminate the `BUS_CVTADDR()' macros which the pmax port inherited from
an old, now-obsolete sys/arch/alpha snapshot.

* Update the comments and debugging code in interrupt handlers to
be consistent with the machine-independent TC support.

Other commits that overlap the same source files include: re-enabling
clock-tick interrupts earlier, and counting hardclock ticks for vmstat -i.

Change the order of members of struct confargs, to be closer to
the sys/dev/tcvar.h TurboChannel configuration structures. (the initializers
in sys/arch/pmax/tc were already changed; the structure definition wasn't,
which broke autoconfiguration.)

Change the signature of interrupt-handlers to take a void *
(a pointer to the softc) and return an int (indicating spurious
interrupts or other conditions.)

src/sys/arch/mips/include tree.

ptrace.h cdefs.h pmap.h signal.h kdbparam.h

Change mips __warn_references() macro to use the ELF warning features
in binutils 2.6 and (patched) gcc 2.7.2. Only works with gcc in ANSI C
mode, for now.

Use Alpha cdefs.h

Changed name of __weak_reference() to __indr_reference(). They really
are indirect references, and I want to add a real __weak_reference()
macro to <machine/cdefs.h> soon.

This file, which will be included by <sys/cdefs.h>, will contain macros
such as __warn_references() and __weak_reference() which are actually
machine dependant. This will make it easier for ports that are being
bootstraped with ELF and ECOFF based toolchains.

This change also introduces a new macro, _C_LABEL(x). _C_LABEL expands
its argument, an identifier, to a character string of the identifier
name as it is represented in an object file.

For most ports, _C_LABEL(x) will expand to "_x", for ELF based ports
_C_LABEL(x) will expand to "x".

First sweep at scheduler state cleanup. Collect MI scheduler
state into global and per-CPU scheduler state:

- Global state: sched_qs (run queues), sched_whichqs (bitmap
of non-empty run queues), sched_slpque (sleep queues).
NOTE: These may collectively move into a struct schedstate
at some point in the future.

- Per-CPU state, struct schedstate_percpu: spc_runtime
(time process on this CPU started running), spc_flags
(replaces struct proc's p_schedflags), and
spc_curpriority (usrpri of processes on this CPU).

- Every platform must now supply a struct cpu_info and
a curcpu() macro. Simplify existing cpu_info declarations
where appropriate.

- All references to per-CPU scheduler state now made through
curcpu(). NOTE: this will likely be adjusted in the future
after further changes to struct proc are made.

Tested on i386 and Alpha. Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.

upgrade to bsd 4.4-lite code base. only mod is rcsids

intrframe -> clockframe

some pmax updating (Terry Friedrichsen is helping on this now).

update from rick, tarfile of Oct 11 10:46

branches: 1.1.1;
Initial revision

Replace machine/rnd.h with more appropriate name to share it
with cycle counter based microtime in kern/kern_microtime.c.

Cleanup and clarify the ELFSIZE mess:

We now have 2 variables automatically set in elf_machdep.h:

ARCH_ELFSIZE: the size for userland binaries
KERN_ELFSIZE: the size for the kernel binaries

DB_ELFSIZE has been deleted and KERN_ELFSIZE should have always the
same values DB_ELFSIZE used to have.

In sys/exec_elf.h, if ELFSIZE is not set, it is set to KERN_ELFSIZE
for the kernel and ARCH_ELFSIZE for userland. These defaults should
eliminate the need for most manual ELFSIZE setting.

branches: 1.4.14;
obsolete DB_AOUT_SYMBOLS. however, we need to leave most of the code
in db_sym.[ch] as it is used by the elf version of crash(8).

i will be cleaning up the db_sym.c code in a follow up commit to avoid
having dead code compiled.

Initial revision

Add getlabelusesmbr(), as proposed in
http://mail-index.netbsd.org/tech-userlevel/2011/08/25/msg005404.html
This is used by disk tools such as disklabel(8) to dynamically decide is
the undelyling platform uses a disklabel-in-mbr-partition or not
(instead of using a compile-time list of ports).
getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the
machdep #define LABELUSESMBR.
For evbmips, make LABELUSESMBR 1 if the platform uses pmon
as bootloader, and 0 (the previous value) otherwise.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.

Make sure everybody has an splvm() and equate it with splimp() (splimp()
is the historical name for this interrupt level, and the historical name
is going to go away in the near future).

Add spllock(). See spl(9) for details.

Make sure we provide splsched() as described in spl(9).

Change to have cpu_intr() peculiar to DECstations; have ssir global
variable and cpu_intr() body in machdep.c. Reorder and rename
model specific interrupt handler arguments. Fixup machine/intr.h and
machine/cpu.h appropriately.

splsoftnet() should block softclock() too.

Arrange 'vmstat -i' to show 'optslotN'; for interrupt counts of TC slot N
as well as DECsystem 5100 optional serial card slot N.

- Have SYS_DEV_xxx device cookie symbols to select and install proper
interrupt handlers into intrtab[] array, rather than the idea of devices
in 'psuedo' TURBOchannel slots.
- Nuke symbols for psuedo TC slots.
- Abandon never/unlikely used intr_disestablish()s.

Redo interrupt establishment, based in part on work on the
[nisimura-pmax-wscons] branch and suggestions from Toru Nisimura:
- Remove bogus tc_slot_info[] name for interrupt handling array
and replace with simplified struct intrhand intrtab[] array.
- Add intr_establish() and intr_disestablish() function pointers
to struct platform and initialise this in each model-specific
initialisation, and remove global tc_enable_interrupt function
pointer.
- Remove model-specific function declarations from ibus/ibusvar.h.
This is functionally identical to the current scheme, and doesn't
yet try to commonise interrupt establishment by bus type as the
[nisimura-pmax-wscons] branch does.

Also, move cpuspeed variable from autoconf.c to machdep.c

- Fix RCS Ids.

Function prototype cleanup.

branches: 1.8.2;
Change the semantics of splsoftclock() to be like other spl*() functions,
that is priority is rasied. Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.

This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).

XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX. This platforms still have this bug until their
XXX spl*() functions are fixed.

- Call _splnone() explicitely after auto config. was well done to make
sure SOFT_INTs cleared before interrupt processing is started.

- Rework spl(9) implementation. Use _spl*() processor mask manipulating
routines now reside in locore.S. No functional difference is expected.
- Replace abused splx() abuse with _splset() to change MIPS processor
interrupt mask bit. 'mips/trap.c' side will be fixed soon.

branches: 1.5.2; 1.5.10;
Make spl(9) rountines target port dependent. delay() is also port
dependent anticipating a target with high resolution timer available
for on-the-fly re-programming. Enum decstation_t was removed from MI
trap.c.

Define IPL_ constants for pmax.

Split sys/arch/pmaxpmax/{machdep.c,trap.c} as suggested by Jason Thorpe:
* add "Platform" support inpmax/pmax/sysconf.c and pmax/include/sysconf.h
(based on Alpha cpuconf.[ch], with a namechange to avoid clashes with
support for models of MIPS cpus. They differ more than Alphas).

* For each supported model of DECstation, create a separate file
with the support for that model. Use model codenames, since
support is really baseboard-specific and CPU daugherboards can change.
Move code from machdep.c and pmax_trap.c,
Add sysconf (nee "cpuconf") support.

* Rename model-specific functions to match sysconf names.

* Clean up autoconf.c. Use platform callbacks.

* Retire pmax_trap.c.

Leaves I/O bus configuration and console configuration untouched.

Require that each each MACHINE/MACHINE_ARCH supply a lock.h. This file
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED. These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case). Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.

These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.

Define the conventional pmax locore entry-point names to be calls through
an vector (struct) of function pointers. Add prototype declarations for
each vector entry.
Add declarations for the r2000 (MIPS-I) and r4000 (MIPS-III) locore
versions of the relevant functions.

branches: 1.1.4;
Create a new header lwp_private.h to contain _lwp_getprivate_fast,
_lwp_gettcb_fast, _lwp_settcb and remove them from mcontext.h, so that:
1. we don't need special hacks to hide them
2. we can include <lwp.h> where needed to get the necessary prototypes
without redefining them locally.

Remove all references to <machine/machAsmDefs.h>.
Use #include <mips/asm.h> instead.

Rename the original pmax/include/machAsmDefs.h file, with CVS history,
to mips/include/asm.h.

Until all references to <machine/machAsmDefs.h> in the pmax and
pica tree are changed to use <mips/asm.h> directly, just do
#include <mips/asm.h>, for compatibility.

Support for alternate compilers and file formats

Make a new macro _C_LABEL(), which prepends an underscore to the argument unless
NO_UNDERSCORES is defined. Use it in the *LEAF() and END() macros.

bsd 4.4-lite pmax port as ported to NetBSD

upgrade to bsd 4.4-lite code base. only mod is rcsids

branches: 1.1.1;
Initial revision

Remove the machConst.h (wrapper for Sprite-derived source), and all
#includes <machine/machConst.h> uses.
Other header files now include <mips/cpuregs.h> where necessary.

Just include <mips/cpuregs.h>, which has the same contents this
file used to.

Resolve all differences between the Pica and pmax versions of machConst.h:
* add "MIPS_3k_" for the MIPS-I r[23]000-specific register definitions.
* add "MIPS_4k_" for the MIPS-II/III r4000-specific register definitions.
* add #defines that provide the old values for locore and user
code, so the existing code continues to compile.

Regression-tested against the old headers by grepping for #define's,
editing out the defined symbols, and preprocessing with both the previous
machConst.h headers and this version.

Some unused symbols (CPU and FPU must-be-zero constants) are no longer defined.
Pica interrupt masks are now constant expressions instead of constant
values.

TODO:
* factor out the common #defines into src/sys/arch/mips.
* Get rid of the Sprite coding-style names (MACH_xxx).
* Separate out the r3k/r4k differences from the Pica/pmax differences.
* Figure out how to have a run-time choice of r3k vs. r4k support,
instead of a compile-time choice.

Move the definition of MSGBUFSIZE up to the machine-arch level if

Implement the kernel part of pr-1891. This allows for a more flexible sized

Fix typo in NMBCLUSTERS definition.

Remove common-across-all-MIPS-cpu definitions (e.g., user-level-visible
page/segment size definitions and macros) and move them to

add _MACHINE and _MACHINE_ARCH, which are like MACHINE and MACHINE_ARCH,
execpt without quotes. meant to be __CONCAT()ted for easy #includes
of machine-dependent headers for MI code (e.g. for the MI ISA/EISA/PCI/TC

Clean up tabbing/spacing in defns of MACHINE, MACHINE_ARCH, and MID_MACHINE.

LOCORE -> _LOCORE

Add argument prototypes - __P((void)) - to the declarations of Mach_spl*() functions.

kill user-land DELAY macro, as suggested by gwr.

clean up definitions of ctod(), dtoc(), ctob(), btoc(), btodb(), and
dbtob(). remove unused definitions of ctos(), stoc(), and dtob().

KERNEL -> _KERNEL

don't be so quick to cast macro arguments to unsigned; if the
arguments are really off_t's (e.g. to btodb), then you can lose

Remove the kernel PMC code. Sent yesterday on tech-kern@.

This change:

* Removes "options PERFCTRS", the associated includes, and the associated
ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
good.

* Removes the PMC code of ARM XSCALE.

* Removes all the pmc.h files. They were all empty, except for ARM XSCALE.

* Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
definitions are put in sysarch.h.

* Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
netbsd32 and rump.

* Removes the pmc_evid_t and pmc_ctr_t types.
