[PATCH v3 0/2] Support micro operation measurement on arm64

2018-01-17 Thread Shih-Wei Li
The patch provides support for quantifying the cost of micro level operations on arm64 hardware. The supported operations include hypercall, mmio accesses, EOI virtual interrupt, and IPI send. Measurements are currently obtained using timer counters. Further modifications in KVM will be required
