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.

d802b73d94 winit: rename register macros for more clarity
wdbg: cleanup, improve exception catcher (previously potentially failed
if __try block came in non-main thread). required since wstartup no
longer commandeers the entry point.
winit, wstartup: update documentation

This was SVN commit r5141.

db189468a9 (update-workspace required)
found another means of doing startup/shutdown that doesn't require
hooking and allows init callbacks to use CRT functions (avoiding
problems similar to the recent rash of pre-libc bugs). also, callback
registration no longer needs ugly #pragma syntax.

remove 'Detours' (evil and no longer needed)

This was SVN commit r5137.

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.

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.

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.

b879e344f1 make sure winit shutdown actually happens during self-test (fixes leaks and possibly failure to unload driver)
revamp module init: no more atexit and "premain" init => no longer need
to call any wstartup init function. winit section names now use group
numbers instead of letters.

delay_load -> wdll_delay_load
dll_ver -> wdll_ver
add aken build environment
cleanup wsock.cpp, have it import its functions properly
wsdl: defend against GameSetup calling SDL_Quit twice.

This was SVN commit r5108.

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.

4582c8f276 unbreak lockfree test, add sanity checks and timer init
lockfree: avoid potential race condition and add bounds check
whrt: sanity check
test_lockfree: fix by adding call to init/shutdown lockfree
timer: add proper init/shutdown
GameSetup: call lockfree and timer init/shutdown

This was SVN commit r5096.

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.
