Hi, This set of patches remarkably accelerates IDE PIO on HVM/IA64. I got a throughput of 2.11MB/sec in disk read performance. Without it, it was only 64kB/sec. I posted the prototype once. http://lists.xensource.com/archives/html/xen-devel/2006-12/msg00077.html The basic idea is to add a buffering mechanism in a hypervisor. I know this approach is not sophisticated. But there is no other good

Hi. I found this issue with IA64 box while looking at the c/s of 18204:21dd1fdb73d8, but I believe the things is same with x86 box. I''m not sure whether this patch coexist with the old ioemu which is to be removed soon. So it might be desirable to apply this patch after deleting the internal ioemu tree. thanks, xm: Don''t spawn vncviewer twice. Without this patch, vncviewer

Currently xen-unstable.hg is broken on ia64 and it should be fixed by Yu''s patch. However he is off this week, so I''m sending the workaround patch. [IA64] Compilation fix to cpufreq stuff. This patch fixes the following compilation error by defining stubs. This patch is just band aid patch until those functions are implemented later. > .../xen/drivers/built_in.o: In
