[PATCH v2 0/6] kvm: pci PORT IO MMIO and PV MMIO speed tests
...ted on kvm mailing list.
To use, simply add the device on the pci bus.
Example test output:
vmcall 1519
....
outl_to_kernel 1745
....
mmio-no-eventfd:pci-mem 9075
mmio-wildcard-eventfd:pci-mem 3529

mmio-pv-eventfd:pci-mem 1878
portio-no-eventfd:pci-io 5535
portio-wildcard-eventfd:pci-io 1846
portio-datamatch-eventfd:pci-io 1848
portio-pv-eventfd:pci-io 1842
First interesting conclusion is that the overhead of MMIO
exit to QEMU as compared to PIO is double that of
MMIO ioeventfd as compared to PIO eventfd. Is this...

[Patch] the interface of invalidating qemu mapcache
HVM balloon driver or something, that''s under development, may decrease
or increase the machine memory that is taken by HVM guest; in IA32/IA32e
host, now Qemu maps the physical memory of HVM guest based on little
blocks of memory (the block size is 64K in IA32 host or 1M in IA32E
host). When HVM balloon driver decreases the reserved machine memory of
HVM guest, Qemu should unmap the
