[Qemu-devel] [PATCH v1 0/7] kvm: slot handling fixes (and small cleanups)
Posted by David Hildenbrand 6 years, 6 months ago
Hopefully this is the last bunch of fixes for the cleanup series.

1. log_start() was called before region_add(), which is wrong.
2. I messed up the calculation of the delta when aligning the ram address
   (maybe we should simply also use ROUND_UP there ...).
3. I think we could get log_start/log_stop/log_sync when we actually
   haven't registered a slot (due to trapping).
4. Some further cleanups

@Joe, if you could retest, this would be great! I updated the branch.

David Hildenbrand (7):
  memory: call log_start after region_add
  kvm: fix alignment of ram address
  kvm: tolerate non-existing slot for log_start/log_stop/log_sync
  kvm: fix error message when failing to unregister slot
  kvm: region_add and region_del is not called on updates
  kvm: simplify kvm_align_section()
  memory: reuse section_from_flat_range()

Looks good!  I'll wait for testing results if they come soon.

Hi,

I've pulled the updates from David's repo and tested the same branch 
(kvm_slot) and they work beautifully for me. Thanks for fixing this David!
