Subject: [PATCH v3 0/4] x86/spec-ctrl: IPBP improvements
Date: Wed, 25 Jan 2023 16:24:19 +0100 [thread overview]
Message-ID: <930254a6-d0c8-4910-982a-bfd227187240@suse.com> (raw)
Versions of the two final patches were submitted standalone earlier
on. The series here tries to carry out a suggestion from Andrew,
which the two of us have been discussing. Then said previously posted
patches are re-based on top, utilizing the new functionality.
1: spec-ctrl: add logic to issue IBPB on exit to guest
2: spec-ctrl: defer context-switch IBPB until guest entry
3: limit issuing of IBPB during context switch
4: PV: issue branch prediction barrier when switching 64-bit guest to kernel mode
