The AAEON UP Xtreme i12 Core i7-1270PE board is unique, because, in addition to being able to debug it with JTAG using the Intel Direct Connect Interface (DCI), its CPU has support for Virtualization Technology Redirect Protection: VT-rp. VT-rp is a foundational requirement for advanced security features, specifically Hypervisor-managed Linear Address Translation (HLAT), Paging-Write (PW), and Guest-Paging Verification (GPV).
The more complex the embedded FPGA design or system image file the longer it takes to program. The longer it takes to program, the more expensive production is. This is especially true for when embedded files get larger than 10MB. Read more on how Fast Flash Programming can help to dramatically reduce programming times.
In the last couple of articles in this series, Iโ€™ve focused on basic run-control debugging used in conjunction with Intel Processor Trace (Intel PT). In this installment, weโ€™ll start looking at the use of Architectural Event Trace (AET) to explore the Windows hypervisor, and how MSR accesses in particular are handled.
