[PATCH 0/4] Clean up TSAN warnings

Posted by Marc Morcos 1 day, 2 hours ago

When running several tests with tsan, thread races were detected when reading certain variables. This should allieviate the problem.
Additionally, the apicbase member of APICCommonState has been updated to 64 bit to reflect its 36 bit contents.

Marc Morcos (4):
  apic: Resize APICBASE
  thread-pool: Fix thread race
  qmp: Fix thread race
  apic: Make apicbase accesses atomic to fix data race
