[PATCH v2 0/22] KVM: optimize for MMIO handled

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In this version, we fix the bugs in the v1:
- fix broken read emulation spans a page boundary
- fix invalid spte point is got if we walk shadow page table
  out of the mmu lock

And, we also introduce some rules to modify spte in this version,
then it does not need to atomically clear/set spte on x86_32 host
anymore, the performance report of x86_32 host is in the later section

Avi,

I have sampled the operation of lockless shadow page walking as below steps:
- mark walk_shadow_page_get_mmio_spte as 'noinline'
- do the netperf test, the client is on the guest(NIC is e1000) and the server
  is on the host, it can generate large press of mmio access
- using perf to sample it, and the result of 'perf report' is attached

The ratio of walk_shadow_page_get_mmio_spte is 0.09%, the ratio of handle_ept_misconfig
is 0.11%, the ratio of handle_mmio_page_fault_common is 0.07%

I think it is acceptable, your opinion? 

The structure of this patchset:
- Patch 1 ~ patch 3, fix the bugs in KVM
- Patch 4 ~ patch 7, cleanup read/write emulation and cache mmio info for them
  to quickly mmio emulate
- Patch 8 ~ patch 13, cleanup/prepare for mmio page fault support
- Patch 14 ~ patch 18, optimize for spte operation for x86_32 host
- Patch 19 ~ patch 22, implement mmio page fault

Performance report on X86_32 host:
