Subject: [PATCH 01/11] perf script: Add branch types for VM-Entry and VM-Exit
Date: Thu, 18 Feb 2021 11:57:51 +0200	[thread overview]
Message-ID: <20210218095801.19576-2-adrian.hunter@intel.com> (raw)
In-Reply-To: <20210218095801.19576-1-adrian.hunter@intel.com>

In preparation to support Intel PT decoding of virtual machine traces, add
branch types for VM-Entry and VM-Exit.

Note they are both treated as "calls" because the VM-Exit transfers control
to a different address.
