There is no semantics of dependency required for this type of instance. If you would add the stop bit, the code will expand into 2 bundles instead of possibly one in the original form. - Ken -----Original Message----- From: Christian Hildner [mailto:christian.hildner@hob.de] Sent: Tuesday, October 29, 2002 5:43 AM To: linux ia64 kernel list Subject: [Linux-ia64] RAW dependency in ivt.S Hi, testing the kernel 2.4.18 I found a RAW dependency (for P8) in ivt.S in entry alt_dtlb_miss. The lines are cmp.ne p8,p0=r0,r23 (p8) br.cond.spnt page_fault Why I'am not providing a (simple) patch: I' am wondering about taking the privilege level for the decision about taking a page fault or inserting the identity mapped TLB entry. For my understanding there should be checked for region 7.
