Hi, after my vacation I switched from xen-ia64 change-set 11039 to 11635. And now I have a problem with my mini-os executing the efi/pal code (currently the getTime - function from efi). Every time the function gets called I get an trap 22 (Instruction access rights vector). The strange thing is that the trap also occurs if I don't do the mapping of the pal code. I inserted some trace messages in vcpu_itr_i() in xen to see all parameters. But it looks ok. For a test I removed the call of in ia64_itr() in efi_map_pal_code() in the linux code and nevertheless efi_gettimeofday() runs fine (linux as domU). It seems, there is another tlb entry for this page. I saw that the pal/efi stuff was reorganized in the new change-set. Can anybody give me a hint where to look in the memory handling or do some trace messages! I'm currently still not familiar enough with this stuff. Thanks. Dietmar. _______________________________________________ Xen-ia64-devel mailing list Xen-ia64-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-ia64-devel
