Not by patching instructions because SYSENTER and SYSCALL have completely different semantics (e.g. regarding register use). That is why the entry paths are different on both sides. In theory you could switch the entry paths around, but that would be highly kernel version specific. One easy way is to just clear the SEP and SYSCALL32 flags in CPUID, then int 0x80 will be always used. Of course it'll cost you in performance significantly. I wouldn't recommend to make it default. -Andi -- [EMAIL PROTECTED] -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
