janwas 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.

janwas 4fbaea3780 # fix for exceptions when not running in debugger
move exception-specific stuff into wseh. it now grabs the entry point
and wraps it in a __try block (but only for the main EXE).
this works around issues with the previous SEH registration code
(exceptions weren't caught in release mode when not running in debugger)

This was SVN commit r5151.

janwas cba876b246 bugfixes+cleanup
aken: clean up debug strings
mahaf: use checked/free version of aken depending on config. refactor to
eliminate goto.
hpet: avoid undefined unmap if HPET not found
whrt/*: make sure all counter class data is initialized
whrt: prefer QPC over PMT (it's much faster?!)
winit: add some instrumentation
wutil: win_exe_dir and win_sys_dir shouldn't end in slash. fixed.

janwas 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.

janwas 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.
