Subject: [Qemu-devel] [PATCH 18/36] i386: remove the 'INTEL_PT' CPUID bit from named CPU models
Date: Tue, 23 Jul 2019 12:00:46 -0500 [thread overview]
Message-ID: <20190723170104.4327-19-mdroth@linux.vnet.ibm.com> (raw)
In-Reply-To: <20190723170104.4327-1-mdroth@linux.vnet.ibm.com>
From: Paolo Bonzini <pbonzini@redhat.com>
Processor tracing is not yet implemented for KVM and it will be an
opt in feature requiring a special module parameter.
Disable it, because it is wrong to enable it by default and
it is impossible that no one has ever used it.

(cherry picked from commit 4c257911dcc7c4189768e9651755c849ce9db4e8)
