Hi Dave
I found a problem in arm.c that arm_get_crash_notes() is called too early. This has never been a problem until now.
arm_get_crash_notes() in arm.c
calls readmem(, KVADDR, )
which calls kvtop()
which calls machdep->kvtop that is arm_kvtop
which uses vt->vmalloc_start
vt->vmalloc_start is initialized in vm_init
From main_loop:
machdep_init(POST_GDB);
vm_init();
machdep_init(POST_VM);
arm_get_crash_notes() is currently called in the POST_GDB section of machdep_init, but should be moved to the POST_VM section. I put the comment and the code just before:
if (init_unwind_tables()) {
and then it works fine. Without this fix the crash registers might be read from the wrong physical address.
