Hi All,
This is a follow up discussion on the crash issue being discussed on the
IRC on 15th Sep.
For the context, the issue is as follows :-
Crash logs - https://pastebin.com/F2BKbW5a
Codebase :-
https://gitlab.com/ayankuma/xen-integration/-/tree/integration/mpu
The crash is observed in idle_loop() --> scrub_free_pages() -->
scrub_one_page(&pg[i]) --->
unmap_domain_page(memset(__map_domain_page(pg), SCRUB_BYTE_PATTERN,
PAGE_SIZE));
&pg[i] = 0x6f002400
_map_domain_pg(0x6f002400) = 0x00122000
0x122000 has been marked as read only in early_fdt_map() because dtb is
mapped in the region. See
(XEN) MODULE[1]: 0000000000122000 - 0000000000122d22 Device Tree
Thus, I am not very sure what I need to fix.
Is the address returned by __map_domain_page(pg) is incorrect ?
Any pointers/guidance is appreciated.
Kind regards,
Ayan
