[PATCH RESEND] KVM: Add coalesced PIO support

2018-07-10 Thread Wanpeng Li
Windows I/O, such as the real-time clock. The address register (port 0x70 in the RTC case) can use coalesced I/O, cutting the number of userspace exits by half when reading or writing the RTC. Guest access rtc like this: write register index to 0x70, then write or read data from 0x71. writing
