Subject: [PATCH v2 0/2] Inject a PMI for KVM Guest when ToPA buffer is filled
Date:   Mon, 18 Feb 2019 19:26:06 -0500
Message-Id: <1550535968-7652-1-git-send-email-luwei.kang@intel.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Each intel processor trace table of physical addresses (ToPA) entry
has an INT bit. If this bit is set, the processor will signal a
performance-monitoring interrupt (PMI) when the corresponding trace
output region is filled. This patch set will inject a PMI for Intel
Processor Trace when ToPA buffer is filled.

>From v1:
 - Exported a global function pointers may not a good chioce.
   Add a new member in kvm_guest_cbs to send Intel PT PMI for KVM guest.
