Subject: [PATCH 0/3] KVM: x86: cleanup and fixes for debug register accesses
Date: Mon, 4 May 2020 11:55:55 -0400 [thread overview]
Message-ID: <20200504155558.401468-1-pbonzini@redhat.com> (raw)
The purpose of this series is to get rid of the get_dr6 accessor
and, on Intel, of set_dr6 as well. This is done mostly in patch 2,
since patch 3 is only the resulting cleanup. Patch 1 is a related
bug fix that I found while inspecting the code.
A guest debugging selftest is sorely needed if anyone wants to take
a look!
