Make crypto/rijindael optional again as cprng_strong does no longer
depend on it. Dependency is explicitly declared in files.foo if a
component requires it.

Reorganise sources to make it possible to include Xen PVHVM support in
native kernels. Among others:
- move xen/include/amd64/hypercall.h to amd64/include/xen and
  xen/include/i386/hypercall.h to i386/include/xen
- exclude some native files from the build for xenpv
- add xen to "machine" config statement for amd64 and i386
- split arch/xen/conf/files.xen to arch/xen/conf/files.xen (for pv drivers)
  and arch/xen/conf/files.xen.pv (for full pv support)
- add GENERIC_XENHVM kernel config which includes GENERIC and add Xen PV
  drivers.

Multiboot2 kernel support for i386

That implementation works either with BIOS or UEFI bootstrap

This requires the following kernel changes:

Add UEFI boot services and I/O method protoypes
src/sys/arch/x86/include/efi.h 1.8 - 1.9

Fix EFI system table mapping in virtual space
src/sys/arch/x86/x86/efi.c 1.19 - 1.20

Make sure no bioscall is issued when booting off UEFI system
src/sys/arch/i386/i386/machdep.c 1.821 - 1.822
src/sys/arch/i386/pci/piixpcib.c 1.22 - 1.23

And the following bootstrap changes:

Add kernel symbols for multiboot1
src/sys/arch/i386/stand/lib/exec_multiboot1.c 1.2 - 1.3
src/sys/arch/i386/stand/lib/libi386.h 1.45 - 1.47

Fix kernel symbols for multiboot2

Sync with HEAD, resolve a few conflicts

This change modifies the mainbus(4) entry point for all x86 sub-archs
in the following way:

i) It provides a unified entry point in
   x86/x86/mainbus.c:mainbus_attach()
ii) It carves out the preliminary bus attachment sequence that is
   common to all sub-archs into
   x86/x86/mainbus.c: x86_cpubus_attach()
iii) It consolidates the remaining pathways as internal callee
   functions so that these may be called piecemeal if required. A
   special usecase of this is XEN PVHVM which may need to call the
   native configure path, the xen configure path, or both.
iv) It moves the driver private data structures from
   i386/i386_mainbus.c to an x86/ level one. This allows for other
   sub-arch's to do similar, if needed. (They do not at the moment).
v) For dom0 kernels, it enables 'acpi0 at mainbus?' and
   'acpi0 at hypervisorbus'. This serves two purposes:
   a) To demonstrate the possibility of dynamic configuration tree
      traversal ordering changes.
   b) To allow for the common acpi_check(self, "acpibus") call in
   x86/mainbus.c to not barf when it is called from the dom0 attach
   path. We allow for the acpi0 device to be a child of mainbus with
   the changes to amd64/conf/XEN3_DOM0 and i386/conf/XEN3PAE_DOM0
   without actually probing further in the code. This path will later
   be pursued in a PVHVM boot codepath.

There should be no operative changes with this change. If there are,
please complain loudly.

Move mainbus(4) driver files in various x86 sub-archs to name prefixed
versions. This allows us to further modularise them by unifying common
bus probe code in x86/x86/mainbus.c to  be introduced next.

This commit has no functional changes. It is done for ease of

Remove the X86PMC code I had written, replaced by tprof. Many defines
become unused in specialreg.h, so remove them. We don't want to add
defines all the time, there are countless PMCs on many generations, and

Remove ipkdb from i386. Also remove unused references in amd64.

I already talked about doing that six months ago on port-i386@. Back then
it was as general cleanup, but now, with SVS etc, we do actually have
good reasons for simplifying the entry points.

Ok kamil@. (christos@ was in the conversation too)

Since SVS is now defined in files.x86, remove it from files.amd64
and files.i386.

Add a new option, SVS (for Separate Virtual Space), that unmaps kernel
pages when running in userland. For now, only the PTE area is unmapped.

Remove support for vm86 on i386. It is bug-friendly, and there is no point
in having kernel support for this: the instruction set of the CPU is small,
and it can easily be emulated in userland entirely. There are also several
assumptions in the code that are not respected, and the slightest confusion
in the trap frame can lead to ring0 exploits.

vm86 has received zero maintenance. As far as I can tell, it was added
20 years ago in order to make doscmd work. But doscmd has not been
maintained either, and was removed from pkgsrc in 2011. dosbox can be used
instead: it does not require kernel support, and will produce better
results than our flimsy implementation.

Pass 1. (many pieces still in the tree)

Remove compat_ibcs2 from i386. After a discussion on port-vax, it turns
out that compat_ibcs2 does not implement the iBCS2 standard - which is
x86-specific - but rather SVR3. Our real iBCS2 implementation was a
mixture of compat_ibcs2 and compat_svr4, and was only partial. Keeping
support for this in i386 is totally irrelevant today. I also asked on
port-i386 but didn't wait long.

The main issue is that compat_ibcs2 should have been called compat_svr3.
But CVS does not support renaming files, and moving things around is both
painful and tiring, even more so when no one seems to be interested in
doing this work or in the feature at all. For now compat_ibcs2 is available
on Vax and will stay, until someone (not me) cleans it up.

Drop support for svr4 on i386. This feature is not maintained, not
reliable, and of a limited use case. Most svr4 applications got time to be
ported to linux, and we do have a functional, maintained linux emulation.

Reduces the number of entry points into the kernel, the number of
places that need special care (cpu context).

Note that compat_svr4 is still available on sparc.

Add support for hardware assisted watchpoints/breakpoints API in ptrace(2)

Add new ptrace(2) calls:
 - PT_COUNT_WATCHPOINTS - count the number of available hardware watchpoints
 - PT_READ_WATCHPOINT   - read struct ptrace_watchpoint from the kernel state
 - PT_WRITE_WATCHPOINT  - write new struct ptrace_watchpoint state, this
                          includes enabling and disabling watchpoints

The ptrace_watchpoint structure contains MI and MD parts:

typedef struct ptrace_watchpoint {
	int		pw_index;	/* HW Watchpoint ID (count from 0) */
	lwpid_t		pw_lwpid;	/* LWP described */
	struct mdpw	pw_md;		/* MD fields */
} ptrace_watchpoint_t;

For example amd64 defines MD as follows:
struct mdpw {
	void	*md_address;
	int	 md_condition;
	int	 md_length;
};

These calls are protected with the __HAVE_PTRACE_WATCHPOINTS guard.

Tested on amd64, initial support added for i386 and XEN.

Torn down KSTACK_CHECK_DR0, i386-only feature to detect stack overflow

This feature was intended to detect stack overflow with CPU Debug Registers
(x86). It was never ported to other ports, neither amd64 and should be
adapted for SMP...

Currently there might be better ways to detect stack overflows like page
mapping protection. Since the number of Debug Registers is restricted
(4 on x86), torn it down completely.

This interface introduced helper functions for Debug Registers, they will
be replaced with the new <x86/dbregs.h> interface.

KSTACK_CHECK_DR0 was disabled by default and won't affect ordinary users.

Change i386 to use x86/fpu.c instead of i386/isa/npx.c
This changes the trap10 and trap13 code to call directly into fpu.c,
  removing all the code for T_ARITHTRAP, T_XMM and T_FPUNDA from i386/trap.c
Not all of the code thate appeared to handle fpu traps was ever called!
Most of the changes just replace the include of machine/npx.h with x86/fpu.h
  (or remove it entirely).

Convert the amd64 build to use x86/cpu_extended_state.h so that the fpu
  definitions match those of i386.
Mostly just structure and field renames, in addition:
1) process_xmm_to_s87() and process_s87_to_xmm() moved into
   x86/convert_xmm_s87.c so they can be used by amd64's netbsd32 code.
2) The linux signal code simplified to use a structure copy for ths fxsave
   data - it matches the hardware definition and won't change.

Remove support for 'external' floating point units and the MS-DOS
  compatible method of handling floating point exceptions.
Make kernel support for teh fpu non-optional (486SX should still work).
Only 386 cpus support external fpu, and i386 support was removed years ago.
This means that the npx code no longer uses port 0xf0 or interupt 13.
All the "npx at isa" lines go from the configs, arch/i386/isa/npx.c
  is now mandatory for all i386 kernels.
I've renamed npxinit() to fpuinit() and npxinit_cpu() to fpuinit_cpu()
  to match the very similar amd64 functions.
The fpu of the boot cpu is now initialised by a direct call from
  cpu_configure(), this enables FP emulation for a 486SX.
  (for amd64 the cr0 values are set in locore.S and similar).
This fixes a long-standing bug in linux_setregs() - which did not
  save the fpu regsiters if they were active.
I've test booted a single cpu i386 kernel (using anita).
amd64 builds - none of teh changes should affect it.
The i386 XEN kernels build, but I'm not sure where they set cr0, and
  it might have got lost!

Remove the obvious parts of i386 Advanced power management 'apm' support.
This is the code that predates ACPI, and might once have been able to

The APM specification was made obsolete by ACPI before it was widely

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

XXX:    This is broken: it calls methods with absolute pathnames (almost
        guaranteed not to be portable across models), it accesses methods
        that are in the domain of other drivers, it walks the namespace on
        its own, it contains plenty of magic constants, it does not
        integrate with existing KPIs, etc. Summa summarum: this should be
        rewritten as a more generic toshiba_acpi(4).

Add a kernel configuration flag, SPLDEBUG, that activates a per-CPU log

'options SPLDEBUG' adds instrumentation to spllower() and splraise() as
well as routines to start/stop debugging and to record IPL transitions:
spldebug_start(), spldebug_stop(), spldebug_raise(), spldebug_lower().

Split off the Transmeta Crusoe Longrun code into its own file, that
way identcpu.c and machdep.c are not cluttered with foreign code.

The driver is built by default as before, but the sysctl subtree will
only be created if longrun is detected and not always as the old code
did. This matches what the FreeBSD code does.

Ok by christos@.

Since files.wscons et al. are included by ~all ports anyway, include
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.

Refactor in_cksum/in4_cksum/in6_cksum implementations:
- All three functions are included in the kernel by default.
  They call a backend function cpu_in_cksum after possibly
  computing the checksum of the pseudo header.
- cpu_in_cksum is the core to implement the one-complement sum.
  The default implementation is moderate fast on most platforms
  and provides a 32bit accumulator with 16bit addends for L32 platforms
  and a 64bit accumulator with 32bit addends for L64 platforms.
  It handles edge cases like very large mbuf chains (could happen with
  native IPv6 in the future) and provides a good base for new native
  implementations.
- Modify i386 and amd64 assembly to use the new interface.

This disables the MD implementations on !x86 until the conversion is
done. For Alpha, the portable version is faster.

Attach two new devices to the AMD Elan SC520 System Controller,
elansc(4).

elanpex(4) is for PCI exception reporting.  I've already found some
kernel bugs by reading the exceptions reported.  Beware that it
will spam the console a lot while the kernel and pcictl(8) probe
non-existing addresses in PCI configuration space.

elanpar(4) protects the kernel text from writes by the CPU and by
PCI bus masters.  As you might guess, this is not compatible with
setting breakpoints using a debugger; detach the device using
'drvctl -d elanpar0' before you try to set breakpoints.  In the
future, I hope to extend elanpar(4) to provide general-purpose RAM
write-protection.

 CPUs running in 64bit mode.

Patch from jmcneill to make the brightness buttons work on my sony vgn-t250p.

Start to revamp the ACPI wake code (i386 only, amd64 gets minimal fixes
to keep being compilable):

- In init386 and the amd64 equivalent, just reserve the low-level code.
  Do not map and don't copy the wakecode yet. This avoids the conflicts
  with the MP tramp code as well. The wakecode is expected to be less
  than one page long, which is way too much space.
  acpi_md_get_npages_of_wakecode and acpi_md_install_wakecode are
  dropped, acpi_wakeup_paddr is set instead of the reserved address.
- Split the wakecode into the essential low-level part to setup
  protected mode with paging and valid CS and DS (which stays as
  wakecode) and the rest. Inline beepon and beepoff as they are used
  exactly once.
- Split the acpi_restorecpu and acpi_savecpu assembly from apci_wakeup.c
  and merge acpi_restorecpu with the second half dropped from wakecode.
  Most registers are not exported, just those needed to be patched into
  wakecode. Don't bother to save or restore %eax, it is overriden
  anyway.
- Don't bother to save and restore eflags in acpi_md_sleep, they are
  handled correctly by the assembly. Don't play games with cr3 either,
  we modify the pmap of the running processes. Copy the wakecode
  directly before patching it, after the identity mapping has been
  setup.
- Drop clear_reg and acpi_printcpu.
- Add an commented out broadcast IPI to halt the other CPUs explicitly.

clean up how cpus and ioapics are attached at the mainbus:
Seperate "cpubus" and "ioapicbus" -- while they share a common "address
space" (the apic id), the kernel doesn't use this fact. There are different
data passed to cpus and apics, which caused some ugly polymorphism. This
also saves the special "submatch" functions needed to distingush cpus
and ioapics for autoconf. (And it makes that "apid" locators wired
in the kernel configuration are honored now; this allows one to dumb down
an mp box to singleprocessor by userconfig.)
Print "apid" locators in the buses "print" function "as everyone does",
so the per-port cpu drivers don't need to do it.
Being here, constify "struct cpu_functions" and g/c the unused MP_PICMODE
flag.

Mark MULTIBOOT_SYMTAB_SPACE obsolete instead of silently removing it.
Per cube@'s suggestion.

Remove the usage of Multiboot's "a.out kludge" to tell the boot loader to
reserve some more space for the BSS section than the binary says.  This
trick was used to leave room after the kernel's image to copy the symbol
table following the format required by ksyms_init.  (It was also used to
workaround a bug in the physical address fields of the binary, but this has
been long fixed.)  Yes, the MULTIBOOT_SYMTAB_SPACE option goes away; yay!

Instead, copy the required data after the kernel in a way that avoids having
to reserve space and use the new ksyms_init_explicit function to avoid the
need to construct a minimal ELF image.

Fixes ksyms when using an "unpatched" GRUB (one that does not contain the
fix to honour the "a.out kludge" for ELF images, even when present) -- i.e.
ddb and lkms.  As a side effect, the new code is much clearer to read and
digest.

is only compiled in if ipmi(4) is configured). The sensors and watchdog are
accessible though envsys(4).
Works on i386; some work is needed on amd64 to access the BIOS. It would
eventually work on Xen if the SMBios is accessible (to be tested).

A number of minor changes for NDIS.  (OK'd by phil)

1. Removed the makeoptions line from arch/i386/conf/GENERIC.  Now
ndis_driver_data.h is simply copied into the kernel build directory instead
of editing the config file to specify its location.

2. Uncommented lines in files.i386 and files.pci related to NDIS.  NDIS will
not be compiled into the kernel unless the two lines are uncommented from
GENERIC (I checked using nm), so there is no reason for this to be commented
out.

3. Added ndiscvt to usr.sbin/Makefile.

Convert existing ath users to new Makefile, except for amd64, which needs
the rules due to needing to conditionally postprocess the HAL object file.

Macppc needs a a non-ELF HAL (EABI) object, so take care of that by default
in the atheros include file.

Merge 2006-03-31 NetBSD-current into the "peter-altq" branch.

Updated to the latest NDIS code.  I added commented out lines in the files
arch/i386/conf/GENERIC, arch/i386/conf/files.i386 and dev/pci/files.pci which
can simply be uncommented to compile NDIS into the kernel.  I'll write some
documentation on this soon.

Note that NDIS is still somewhat experimental.  It is currently tested and
functions relatively well on on two cards:
1. Dell (Broadcom) TrueMobile 1400 Dual Band WLAN Mini-PCI
2. Intel EtherExpress Pro/100

Backout part of previous since it breaks kernel build and not described

It turns out that pci_addr_fixup() doesn't require PCIBIOS either.  Decouple,
run it from mainbus_attach().

Rework the configuration scheme for PCI fixups:

* bus enumeration fixups are not PCIBIOS-specific, interrupt fixups are done
  by both PCIBIOS and ACPI.  The redundancy is very redundant.  Therefore,
  rename PCIBIOS_*_FIXUP to PCI_*_FIXUP, use PCI_INTR_FIXUP in place of
  ACPI_PCI_FIXUP, and change code refences to match.

* move the fixup defines from opt_pcibios.h to opt_pcifixup.h to reflect
  the above.

* fix up the PCI bus numbering in mainbus_attach(), right after we detect the
  configuration mode.  This probably renders the fixup in pcibios.c
  redundant -- but it should be harmless.

These changes make cardbus work in ACPI-only machines, when PCI_BUS_FIXUP
and PCI_INTR_FIXUP are defined.

Move linux_trap.c from sys/arch/i386/i386 to sys/arch/x86/x86, and share
it. Remove the amd64 linux_trap.c (which was just a stub with a printf
anyway).

remove the (superfluous) definition of "cpu" as an interface attribute

Phase out the use of a string as first "attach args" member to control
which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.

Add an option to allow any user to write to machdep.est.frequency.target,
which is very handy on a laptop to control EST through another program that
you don't necessarily want to run as root (in my case, gkrellm).

The option's name is EST_FREQ_USERWRITE, and is disabled by default.

Integrate support for Enhanced SpeedStep Technology (est) that
Michael Eriksson posted to port-i386 on 20031102, with various
modifications by me to work in the new sysctl(9) framework.

The code is enabled with 'options ENHANCED_SPEEDSTEP', and if
the CPU supports EST the following sysctl(8) nodes appear
(with the values that a Dell Inspiron 8600 + WUXGA with a
1.4GHz Pentium M CPU supports):
	machdep.est.cpu_brand = Intel(R) Pentium(R) M processor 1400MHz
	machdep.est.frequency.target = 1400
	machdep.est.frequency.current = 1400
	machdep.est.frequency.available = 1400 1200 1000 800 600

If EST support isn't available, the "machdep.est" sysctl sub-MIB
is not created.

Once we have a more general "CPU frequency" control API we can
migrate this code to using that.

Thanks to Michael Erikkson for providing this code!
