memory fault handler. IRIX uses irix_vm_fault, and all other emulation use NULL, which means to use uvm_fault. - While we are there, explicitely set to NULL the uninitialized fields in struct emul: e_fault and e_sysctl on most ports - e_fault is used by the trap handler, for now only on mips. In order to avoid intrusive modifications in UVM, the function pointed by e_fault does not has exactly the same protoype as uvm_fault: int uvm_fault __P((struct vm_map *, vaddr_t, vm_fault_t, vm_prot_t)); int e_fault __P((struct proc *, vaddr_t, vm_fault_t, vm_prot_t)); - In IRIX share groups, all the VM space is shared, except one page. This bounds us to have different VM spaces and synchronize modifications to the VM space accross share group members. We need an IRIX specific hook to the page fault handler in order to propagate VM space modifications caused by page faults. |
