[Qemu-devel] [PATCH v3 0/9] target-i386: Implement debug extensions

[Eduardo Habkost]

Updated version of the series submitted by Richard Henderson.

With the additional changes, the kvm-unit-tests debug extensions test case
written by Paolo passes all tests except ICEBP.

Changes v2 -> v3:
* Patch 3/9: Set bit on new_dr7, so that it can still pass the xor test
  for the enable bits optimization
  * Suggested-by: Richard Henderson <address@hidden>
* Patch 6/9: coding style fix (remove unnecessary parentheses)

Changes v1 -> v2:
* Patch 2/9: Included fix from Paolo to make sure dr7 is updated
  after hw_breakpoint_remove() call and before hw_breakpoint_insert()
  call
* New patch (3/9): Ensure bit 10 on DR7 is never cleared
* Patch 6/9: Rebase on top of new version of patch 2/9
* New patch (8/9): Ensure always-1 bits on DR6 can't be cleared
* New patch (9/9): Add DE to TCG_FEATURES
