Indeed. Note how the |= cleverly accommodates both truncating and non-truncating cpu_get_phys_page_debug(). > >> But it looks like cpu_get_phys_page_debug was broken for quite a while. >> Let's fix those archs to return more than page-aligned addresses. > > You mean make them all return full physical address? > I'd propose to rename the function then as well. > Agree to both. cpu_translate_virtual_address() or similar would be more explanatory IMO. btw, how does the thing work for soft-tlb cpus? It looks like this thing should trigger on tlb loads, not when the breakpoint is set. This is true for hardware page tables as well, as the mapping can change, though it's less likely. -- error compiling committee.c: too many arguments to function
