14 years agoUse Little Endian for Dirty Log
Alexander Graf [Mon, 27 Jul 2009 10:49:56 +0000 (12:49 +0200)]
Use Little Endian for Dirty Log

We currently use host endian long types to store information
in the dirty bitmap.

This works reasonably well on Little Endian targets, because the
u32 after the first contains the next 32 bits. On Big Endian this
breaks completely though, forcing us to be inventive here.

So Ben suggested to always use Little Endian, which looks reasonable.

We only have dirty bitmap implemented in Little Endian targets so far
and since PowerPC would be the first Big Endian platform, we can just
as well switch to Little Endian always with little effort without
breaking existing targets.

This is the userspace part of the patch. It shouldn't change anything
for existing targets, but help PowerPC.

Use 64bit pointer for dirty log

Dirty logs currently get written with native "long" size. On little endian
it doesn't matter if we use uint64_t instead though, because we'd still end
up using the right bytes.

On big endian, this does become a bigger problem, so we need to ensure that
kernel and userspace talk the same language, which means getting rid of "long"
and using a defined size instead.

So I decided to use 64 bit types at all times. This doesn't break existing
targets but will in conjunction with a patch I'll send to the KVM ML make

- The code was incorrectly overwriting the high order 32
  bits of the timer and hpet config registers. This didn't show up
  in testing because linux and windows use hpet in legacy mode,

  of the timer config register are ignored, and the high order 32
  bits of the hpet config register are reserved and unused.

- The mask for level-triggered interrupts was off by a bit. (hpet
  doesn't currently support level-triggered interrupts).

In addition, I removed some unused #defines, and corrected the ioapic
interrupt values advertised. I'd set this up early in hpet development
and never went back to correct it, and no bugs resulted since linux and
