54a8c69347 Stage 1 of a cleanup of the i386 interrupt registration mechanism.
Interrupts under the new scheme are managed by the i386 nexus with the
awareness of the resource manager.  There is further room for optimizing
the interfaces still.  All the users of register_intr()/intr_create()
should be gone, with the exception of pcic and i386/isa/clock.c.

6182fdbda8 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

2005b07aa8 1. Modify config to issue different code for debugging.
2.  Config complains if you use -g:

    Debugging is enabled by default, there is no ned to specify the -g option

3.  Config warns you if you don't use -s:

    Building kernel with full debugging symbols.  Do
    "config -s BSD" for historic partial symbolic support.
    To install the debugging kernel, do make install.debug

    (BSD was the name of the config file I used; I print out the same
    name).

4.  Modify Makefile.i386, Makefile.alpha, Makefile.pc98 and config to
    work if a kernel name other than 'kernel' is specified.  This is
    not absolutely necessary, but useful, and it was relatively easy.
    I now have a kernel called /crapshit :-)

5.  Modify Makefile.i386, Makefile.alpha, Makefile.pc98 "clean" target
    to remove both the debug and normal kernel.

6.  Modify all to install the stripped kernel by default and the debug
    kernel if you enter "make install.debug".

7.  Update version number of Makefiles and config.

8fe2c75e31 Make the xl and pn drivers work on FreeBSD/alpha and add them to
sys/alpha/conf/GENERIC.

Note: the PNIC ignores the lower few bits of the RX buffer DMA address,
which means we have to add yet another kludge to make it happy. Since
we can't offset the packet data, we copy the first few bytes of the
received data into a separate mbuf with proper alignment. This puts
the IP header where it needs to be to prevent unaligned accesses.

Also modified the PNIC driver to use a non-interrupt driven TX
strategy. This improves performance somewhat on x86/SMP systems where
interrupt delivery doesn't seem to be as fast with an SMP kernel as
with a UP kernel.

e9deda23ae Keyboard driver update in preparation for the USB keyboard driver.
- Refined internal interface in keyboard drivers so that:
  1. the side effect of device probe is kept minimal,
  2. polling mode function is added,
  3. and new ioctl and configuration options are added (see below).

- Added new ioctl: KDSETREPEAT
  Set keyboard typematic rate.  There has existed an ioctl command,
  KDSETRAD, for the same purpose.  However, KDSETRAD is dependent on
  the AT keyboard.  KDSETREPEAT provides more generic interface.
  KDSETRAD will still be supported in the atkbd driver.

- Added new configuration options:
  ATKBD_DFLT_KEYMAP
  Specify a keymap to be used as the default, built-in keymap.
  (There has been undocumented options, DKKEYMAP, UKKEYMAP, GRKEYMAP,
  SWKEYMAP, RUKEYMAP, ESKEYMAP, and ISKEYMAP to set the default keymap.
  These options are now gone for good.  The new option is more general.)

  KBD_DISABLE_KEYMAP_LOADING
  Don't allow the user to change the keymap.

e7ba67f274 Removed all traces of `p_switchtime'. The relevant timestamp is per-cpu,
not per-process.  Keep it in `switchtime' consistently.

It is now clear that the timestamp is always valid in fork_trampoline()
except when the child is running on a previously idle cpu, which
can only happen if there are multiple cpus, so don't check or set
the timestamp in fork_trampoline except in the (i386) SMP case.
Just remove the alpha code for setting it unconditionally, since
there is no SMP case for alpha and the code had rotted.

faa273d5c2 Rip out PQ_ZERO queue. PQ_ZERO functionality is now combined in with
PQ_FREE.  There is little operational difference other then the kernel
    being a few kilobytes smaller and the code being more readable.

    * vm_page_select_free() has been *greatly* simplified.
    * The PQ_ZERO page queue and supporting structures have been removed
    * vm_page_zero_idle() revamped (see below)

    PG_ZERO setting and clearing has been migrated from vm_page_alloc()
    to vm_page_free[_zero]() and will eventually be guarenteed to remain
    tracked throughout a page's life ( if it isn't already ).

    When a page is freed, PG_ZERO pages are appended to the appropriate
    tailq in the PQ_FREE queue while non-PG_ZERO pages are prepended.
    When locating a new free page, PG_ZERO selection operates from within
    vm_page_list_find() ( get page from end of queue instead of beginning
    of queue ) and then only occurs in the nominal critical path case.  If
    the nominal case misses, both normal and zero-page allocation devolves
    into the same _vm_page_list_find() select code without any specific
    zero-page optimizations.

    Additionally, vm_page_zero_idle() has been revamped.  Hysteresis has been
    added and zero-page tracking adjusted to conform with the other changes.
    Currently hysteresis is set at 1/3 (lo) and 1/2 (hi) the number of free
    pages.  We may wish to increase both parameters as time permits.  The
    hysteresis is designed to avoid silly zeroing in borderline allocation/free
    situations.

47633640aa Change the load address of the ELF dynamic linker from "2L*MAXDSIZ"
to an architecture-specific value defined in <machine/elf.h>.  This
solves problems on large-memory systems that have a high value for
MAXDSIZ.

The load address is controlled by a new macro ELF_RTLD_ADDR(vmspace).
On the i386 it is hard-wired to 0x08000000, which is the standard
SVR4 location for the dynamic linker.

On the Alpha, the dynamic linker is loaded MAXDSIZ bytes beyond
the start of the program's data segment.  This is the same place
a userland mmap(0, ...) call would put it, so it ends up just below
all the shared libraries.  The rationale behind the calculation is
that it allows room for the data segment to grow to its maximum
possible size.

These changes have been tested on the i386 for several months
without problems.  They have been tested on the Alpha as well,
though not for nearly as long.  I would like to merge the changes
into 3.1 within a week if no problems have surfaced as a result of
them.

2907af2a96 Mostly remove the VM_STACK OPTION.
This changes the definitions of a few items so that structures are the
same whether or not the option itself is enabled. This allows
people to enable and disable the option without recompilng the world.

As the author says:

|I ran into a problem pulling out the VM_STACK option.  I was aware of this
|when I first did the work, but then forgot about it.  The VM_STACK stuff
|has some code changes in the i386 branch.  There need to be corresponding
|changes in the alpha branch before it can come out completely.

what is done:
|
|1) Pull the VM_STACK option out of the header files it appears in.  This
|really shouldn't affect anything that executes with or without the rest
|of the VM_STACK patches.  The vm_map_entry will then always have one
|extra element (avail_ssize).  It just won't be used if the VM_STACK
|option is not turned on.
|
|I've also pulled the option out of vm_map.c.  This shouldn't harm anything,
|since the routines that are enabled as a result are not called unless
|the VM_STACK option is enabled elsewhere.
|
|2) Add what appears to be appropriate code the the alpha branch, still
|protected behind the VM_STACK switch.  I don't have an alpha machine,
|so we would need to get some testers with alpha machines to try it out.
|
|Once there is some testing, we can consider making the change permanent
|for both i386 and alpha.
|
[..]
|
|Once the alpha code is adequately tested, we can pull VM_STACK out
|everywhere.

a671d614ca Reserve a major number for use by the Iprobe device driver.
Iprobe is an alpha-only system profiling suite which I'm porting from
Linux/alpha to FreeBSD.

Iprobe works by using the hardware profiling support built into
alpha cpus.  In a nutshell,  what Iprobe does is to setup the alpha
performance counters to sample the pc at a fairly high rate & dumps
those pc samples out to user space.  Then some code runs to map the
sampled PCs to functions.  You get a bit more than that (like the PSL
word, so you can tell if you're in the kernel or userland, what the
ipl is, etc).

9c0fed3dcf Various changes to support OSF1 emulation:
* Move the user stack from VM_MAXUSER_ADDRESS to a place below the 32bit
  boundary (needed to support 32bit OSF programs).  This should also save
  one pagetable per process.
* Add cvtqlsv to the set of instructions handled by the floating point
  software completion code.
* Disable all floating point exceptions by default.
* A minor change to execve to allow the OSF1 image activator to support
  dynamic loading.

486bddb033 Fix some 64bit truncation problems which crept into SYSCTL_LONG() with the
last cleanup.  Since the oid_arg2 field of struct sysctl_oid is not wide
enough to hold a long, the SYSCTL_LONG() macro has been modified to only
support exporting long variables by pointer instead of by value.

- created internal names for fixed-size integral types, like __int32_t. They
  will be used to make several headers self-sufficient.
- <stdlib.h> don't include <machine/types.h> anymore.
- created <sys/inttypes.h>, which can be used as <inttypes.h>.
- declaration of uoff_t and ufs_daddr_t moved to <sys/types.h>.

4c56fcdead Removed the cast to a pointer in the definition of PS_STRINGS and
adjusted related casts to match (only in the kernel in this commit).
The pointer was only wanted in one place in kern_exec.c.  Applications
should use the kern.ps_strings sysctl instead of PS_STRINGS, so they
shouldn't notice this change.

f7c9e34bea If there is no .depends file, use the standard ad-hoc way of ensuring
that the generated files are generated before any of the object files.
Also minor cleanup of dependencies in conf/files that I bogusly added
before.

This should fix the requirement that make depend be done starting from
a clean config directory.  If you don't have a clean directory, make
depend is still required if you want the proper .o's to be recompiled.

2127f26023 Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

5b38fe900d Implement 'software completion' for floating point arithmetic. On the
alpha, operations involving non-finite numbers or denormalised numbers
or operations which should generate such numbers will cause an arithmetic
exception.  For programs which follow some strict code generation rules,
the kernel trap handler can then 'complete' the operation by emulating
the faulting instruction.

To use software completion, a program must be compiled with the arguments
'-mtrap-precision=i' and '-mfp-trap-mode=su' or '-mfp-trap-mode=sui'.
Programs compiled in this way can use non-finite and denormalised numbers
at the expense of slightly less efficient code generation of floating
point instructions.  Programs not compiled with these options will receive
a SIGFPE signal when non-finite or denormalised numbers are used or
generated.
