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.	2007-06-12 23:29:27 +00:00
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.	2007-05-28 09:25:38 +00:00
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.	2007-05-26 16:57:39 +00:00
