Get TSC frequency from CPUID 0x15 and/or x16 for newer Intel processors.

 - If the max CPUID leaf is >= 0x15, take TSC value from CPUID. Some processors
   can take TSC/core crystal clock ratio but core crystal clock frequency
   can't be taken. Intel SDM give us the values for some processors.
 - It also required to change lapic_per_second to make LAPIC timer correctly.
 - Add new file x86/x86/identcpu_subr.c to share common subroutines between
   kernel and userland. Some code in x86/x86/identcpu.c and cpuctl/arch/i386.c
   will be moved to this file in future.
 - Add comment to clarify.

	common/lib/libc/sys/cpuset.c: revision 1.21
	usr.sbin/cpuctl/cpuctl.c: revision 1.30

Fix bug, the computation of cpuset_nentries was incorrect, we must do +1
to be able to address the last 32 bits.

On a machine with 80 CPUs, this caused "cpuctl identify >64" to return
garbage.

Check the return value of cpuset_set(), to prevent future surprises.

implement cpuctl identify for sparc and sparc64.

sparc:
- move enum vactype and struct cacheinfo into cpu.h
- move the cache flags from cpuinfo.flags into CACHEINFO.c_flags
  (this allows the new cache_printf_backend() to see them.)
  remove unused CPUFLG_CACHEIOMMUTABLES and CPUFLG_CACHEDVMA.
- align xmpsg to 64 bytes
- move cache_print() into cache_print.h so it can be shared with
  cpuctl.  it only depends upon a working printf().
- if found, store the CPU node's "name" into cpu_longname.  this
  changes the default output to show the local CPU not the
  generic CPU family.  eg:
  cpu0 at mainbus0: mid 8: Ross,RT625 @ 90 MHz, on-chip FPU
  vs the generic "RT620/625" previously shown.
- for each CPU export these things:
  - name
  - fpuname
  - mid
  - cloc
  - freq
  - psr impl and version
  - mmu impl, version, and number of contexts
  - cacheinfo structure (which changed for the first time ever
    with this commit.)

sparc64:
- add a minimal "cacheinfo" structure to export the i/d/e-cache
  size and linesize.
- store %ver, cpu node "name" and cacheinfo in cpu_info.
- set cpu_info ver, name and cacheinfo in cpu_attach(), and
  export them via sysctl, as well as CPU ID and clock freq

cpuctl:
- add identifycpu_bind() that returns false on !x86 as their
  identify routines do not need to run on a particular CPU to
  obtain its information, and use it to avoid trying to set
  affinity when not needed.
- add sparc and sparc64 cpu identify support using the newly
  exported values.

allow most commands to specify more than one cpu.  now you can online or
offline (or identify, or intr/nointr) a list of cpus all together.

convert getcpuid() to take char* not char**

	usr.sbin/cpuctl/arch/x86_64-asm.S: revisions 1.3-1.4
Update cpuctl(8). Microcode and ARM related changes are not included:
- Change the i386 asm x86_identify() so it returns a value instead of
  writing into global data. Fix a stack alignment fubar that would
  cause a crash on a cirix 486. Refactor identify code to common setup
  for normal identify and ucode identify - which was missing a
  memset().
- The Intel and AMD docs (more or less) agree on how the cpuid
  'extended family' and 'extended model' bits are used to create
  larger values than the original 16bit value allowed for.
  Calculate and save these values 'up-front' and use them throughout.
  Untangle the (backwards) nested switch statement for amd 'model 15'
  cpus.
- Use full model number to index name strings - a lot of 256 element
  arrays don't matter in usespace.
- Add support for the xsave related data from cpuid 8.n.
  Reorder the output so that the 'brand' string - which actually
  identifies the cpu is output first.
- Only complain about binding if we have more than 1 cpu.
- Check cpuid leaf 4 for newer Intel CPU to know the cache information.
- Support prefetch size.
- Print the highest extended info level as the basic info level.
- Update URL of AMD's web page.
- Add code to detect hypervisor. The code was based from FreeBSD and
  ported by Kengo Nakahara.
- Add verbose flag.
- Add newline if ci_tsc_freq is 0 to not to break the output.
- Update Intel's processor family names and models.
- Print some more bits.
- Add shared TLB
- Add prototypes.
- Add comments.
- Make some functions static.
- Sort functions.
- KNF.

Fix a bug that an unknown command is printed as "(null)".
Reported by Fredrik Pettai.

 Fix manual and usage bug. The ucode command can take [cpuno] argument.

Rebase to HEAD as of a few days ago.

sync with head.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Add verbose flag.
On x86 cpu, cpuctl -v identify dumps the return values of the cpuid
functions. The max levels are taken from CPUID 0 and CPUID 8000_0000.
It's useful for the future CPU.

Only complain about binding if we have more than 1 cpu. :)
(we always have more than 0).

sync with head

Extend the CPU microcode update framework to support Intel x86 CPUs.
Contrary to the AMD implementation, it doesn't use xcalls to distribute
the update to all CPUs but relies on cpuctl(8) to bind itself to the
right CPU -- to keep it simple and avoid possible problems with
hyperthreading.
Also, it doesn't parse the vendor supplied file to pick the right
part for the present CPU model but relies on userland to prepare
files with specific filenames. I'll commit a pkg for this in a minute
(pkgsrc/sysutils/intel-microcode).
The ioctl interface changed; compatibility is provided (should be
limited to COMPAT_NETBSD6 as soon as this is available).

sync with head

Support CPU microcode loading via cpuctl(8).
Implemented and enabled via CPU_UCODE kernel config option
for x86 and Xen Dom0.
Tested on different AMD machines with different
CPU families.

ok wiz@ for the manpages
ok releng@
ok core@ via releng@

Define _PATH_CPUCTL.

Fix wrong err(3) message (no such thing as IOC_CPU_GETINFO).

Add a cs_hwid field to cpustate and use this to store the ci_cpuid (hardware
ID).  Report this as the HwID in cpuctl.
OK jruoho@.

Third (and last) commit. See http://mail-index.netbsd.org/source-changes/2009/05/13/msg221222.html

Fix -Wsign-compare issue

cpuctl:

- Add interrupt shielding (direct hardware interrupts away from the
  specified CPUs). Not documented just yet but will be soon.

- Redo /dev/cpu time_t compat so no kernel changes are needed.

x86:

- Make intr_establish, intr_disestablish safe to use when !cold.

- Distribute hardware interrupts among the CPUs, instead of directing
  everything to the boot CPU.

- Add MD code for interrupt sheilding. This works in most cases but there is
  a bug where delivery is not accepted by an LAPIC after redistribution. It
  also needs re-balancing to make things fair after interrupts are turned
  back on for a CPU.

Clarify output of 'id' column.

PR port-amd64/37461 x86 cpu dmesg output is noisy

Port identifycpu() to userspace. The kernel lies and reports on cpuN while
actually using the values from cpu0, but this attempts to bind itself to the
requested CPU if running as root. That doesn't work properly yet due to
kern/38588, but will do once that's fixed.

Remove clause 3 and 4 from TNF licenses

Use cpu index instead of ID for cpuctl; extend listing to provide both
numbers (but now the ID is only informational).
