Hello, In processors supporting VPID I think we should invalidate the VPID mapping in the TLB after a shadow invlpg (in case EPT is turned off).

Hello, The fast emulation path patch introduced a bug when we have an event injection during a write to a pagetable: after removing shadows we still jump to the done label, releasing the lock even if we aren''t grabbing it. Inline patch fixes this.

Hello, JIT::recompileAndRelinkFunction's runJITOnFunction does not use the MCI arg, causing null pointer deferences at every call. Attached patch makes runJITOnFunction more reliable. Thanks, Gianluca -- It was a type of people I did not know, I found them very strange and they did not inspire confidence at all. Later I learned that I had been introduced to electronic engineers.

Please add a test to http://llvm.org/viewvc/llvm-project/llvm/trunk/unittests/ExecutionEngine/JIT/JITTest.cpp?view=markup verifying that recompileAndRelinkFunction() keeps working. Then this fix will look fine to me.

This patch implement a very simple non complete reverse map for OOS pages writable mappings to avoid shadow brute-force search on resyncs.

Dear All: I am pretty new to xen-devel, please correct me in the following. Assume we have the following terms GPT: guest page table SPT: shadow page table (Question a) When guest OS is running, is it always using SPT for address translation? If it is the case, how does guest OS refer and modify its own GPT content? It seems that there is a page table entry in SPT for the GPT page. (Question

We''ve got reports of that change causing HVM data corruption issues. While I can''t see what''s wrong with the patch, I''d suggest at least reverting it from the 3.3 tree (which is what our code is based upon) for the time being.

We recently observed a problem with Solaris HVM domains. The bug was seen was seen with a higher number of VCPUs (3 or more), and always had the same pattern: some memory was allocated in the guest, but the first reference caused it to crash with a fatal pagefault. However, on inspection of the page tables, the guests'' view of the pagetables was consistent: the page was present.

Hi. When I compiled xen-3.3-testing with DEBUG_TRACE_DUMP in xen/include/xen/lib.h turned on, I got some errors at SHADOW_PRINTK. The following patch will fix the arguments passed to SHADOW_PRINTK in xen/arch/x86/mm/shadow/common.c and xen/arch/x86/mm/shadow/multi.c. Although I haven''t tested, it is the same for xen-unstable.hg Thanks, Yoshi Signed-off-by: Yoshi Tamura
