7a5655edde # major refactoring of system-dependent code (simplifies build system)
cpu.cpp: avoided the need for wrapper functions by calling the
OS-specific function directly (declared in central header, implemented
in the platform's cpp file)

avoid the need for init in cpu and ia32 via if(!init) Init() pattern.

optimized memcpy now requires SSE support

remove error-prone CAS macro; replace with cpu_CAS
config: no longer require inline asm for float->int conversions
lib_error: remove special-case in CHECK_ERR for windows (no longer
needed)

This was SVN commit r5365.

f331b7313d fix very very insidious bug with mapping physical memory (TLB corruption). fix weirdness reported by michael (underlying cause: using cpu_ClockFrequency instead of wcpu_*; that made the timer run at freq=0)
mahaf: now disabled on Win2k because we can't prevent the TLB bug there.
removed the CopyPhysical API.
wutil: allow querying windows version via number

View: fix warning

This was SVN commit r5169.

bd0d0c0026 # finalize WHRT implementation
cpu: avoid measuring cpu freq if possible
ia32: cleanup, fix #cores detection on AMD (they're incompatible,
*sigh*), add ia32_Generation
wcpu: remove IsThrottling code (clunky and not necessary - we rely on
ia32's feature bit detection instead)
counter: move whrt's counter create code here
qpc: update comment
tsc: finalize IsSafe implementation, remove per-thread stuff (since it
cannot be made to work)
whrt: cleanup, remove calibration code (no longer needed)

This was SVN commit r5121.

5919fc7877 fixes, documentation and cleanup.
. allocators: add static_calloc. also: documention was duplicated in
header; merge it.
. wdir_watch: fix last remaining static object init issues
. add rationale and explanations to lib_errors, wsdl, qpc, whrt.
. cpu/ia32: remove throttling detection (hacky); will be taken care of
by tsc.
. ia32: expose vendor
. wdbg_sym: add its own critical section (safer, less contention)

This was SVN commit r5114.

211999ac6a fixes to timer impls:
pmt: support ACPI 1.0 table name
qpc: just use wcpu_ClockFrequency, can't fail
tsc: do ia32_Init first

This was SVN commit r5111.

52ae284a7e new timer code (esp. HPET) now operational. TSC still disabled pending calibration code.
add update mechanism (needed to safely handle counter rollover) and
lock-free synchronization.

refactor:
. Counters now have Activate/Shutdown interface rather than throwing
exceptions from the ctor.
. whrt is responsible for caching frequency/resolution etc.
. fix counterBits handling

This was SVN commit r5105.

c45ef68a88 add work-in-progress WHRT (win high res timer). works well enough, but calibration is not yet complete nor is TSC usable.
cpu: accessor functions ensure what they return is valid. no longer
needs to call wtime_reset_impl (ugh). uses ModuleInitState.
ia32: add APIC ID accessor and prevent redundant init

This was SVN commit r5093.
