Hi, all
I am sorry for replying late.

This patch uses msg_control to pass vhost callback to macvtap (any better
idea to pass this in a simple way?). vhost doesn't notify guest to release
buffers until the underlying lower device DMA has done for these buffers.
This vq can not be reset if any outstanding reference.

Hi,
Agreed. Like I said previously, I am keeping a detailed list of things you

implementations provide a copy of the faulting instruction bytes

Use these bytes to feed the instruction emulator and avoid the costly

Hi,
version 2 of the DecodeAssist patches.
Changes over version 1:
- goes on top of the CR8 handling fix I sent out earlier this week
(required for proper handling of CR8 exceptions)
- handles exception cases properly (for mov cr and mov dr)
- uses X86_FEATURE_ names instead of SVM_FEATURE
the recent APM Vol.2 and the recent AMD CPUID specification describe
new CPUID features bits for SVM. Name them here for later usage.

Newer SVM implementations provide the GPR number in the VMCB, so
that the emulation path is no longer necesarry to handle debug
register access intercepts. Implement the handling in svm.c and

When the DecodeAssist feature is available, the linear address
is provided in the VMCB on INVLPG intercepts. Use it directly to
avoid any decoding and emulation.
This is only useful for shadow paging, though.
