Query regarding x86_emulate_memop() function
Hi there,
I have a question regarding the functionality of x86_emulate_memop (Xen 3.1) or x86_emulate (Xen 3.2) function. This function gets called from sh_page_fault() function which is invoked when Xen receives a page fault.
Since I am not clear completely about the emulation operation performed by Xen, I have following questions with a below mentioned scenario?

[PATCH]Fix the bug of guest os installation failure and win2k boot failure
Hi, Keir,
This patch is to fix the problem of Linux guest installation failure and Windows 2000 boot failure.
In the early code, we use vmx_vmexit_handler() -> vmx_io_instruction() function to emulate I/O instructions. But now, we use vmx_vmexit_handler() -> handle_mmio -> hvm_emulate_one() -> x86_emulate() to emulate I/O instructions. Also nowadays, the realmode emulation code walks through the path: vmx_realmode() -> realmode_emulate_one() -> hvm_emulate_one() -> x86_emulate().

Need help with fixing the Xen waitqueue feature
The patch ''mem_event: use wait queue when ring is full'' I just sent out
makes use of the waitqueue feature. There are two issues I get with the
change applied:
I think I got the logic right, and in my testing vcpu->pause_count drops
to zero in p2m_mem_paging_resume(). But for some reason the vcpu does
not make progress after the first wakeup. In my debugging there is one

[PATCH RFC v13 00/20] Introduce PVH domU support
This patch series is a reworking of a series developed by Mukesh
Rathor at Oracle. The entirety of the design and development was done
by him; I have only reworked, reorganized, and simplified things in a
way that I think makes more sense. The vast majority of the credit
for this effort therefore goes to him. This version is labelled v13
because it is based on his most recent series, v11.
