I took the liberty of adding a few more printfs in order to dig a bit deeper.
and I got stuck in uvm_addr_invoke(), which calls an unknown to me uaddr_select
function via a pointer.
the particular pointer address being used does not seem to belong to the
_select functions within uvm_addr.c however - see the dmesg outputs. so maybe
there is a place where &kv_any's _select function used was created from scratch?
attached you'll find 3 files:
- current patch against /sys OPENBSD_7_9 for printf context
- dmesg with vis_limit 4GB, resizebar and above 4G decoding enabled in bios
- dmesg with vis_limit 4GB, resizebar and above 4G decoding disabled in bios
I guess you're no longer interested in the 2GB vis_limit since it will not
trigger any additional err messages.
also I see no notable changes if I enable/disable those 2 options in bios, I
will leave them on from now on.
I am used to write code for 16bit microcontrollers so please allow me to
accommodate a bit with this virtual memory mapping madness :)
best regards,
peter
