phys_page_find (exec.c) returns sometimes a page for addresses where nothing is connected.
One example, done with qemu-system-sparc -M SS-20 ok f13ffff0 2f spacec@ . // The address translates correctly, in cpu_physical_memory_rw // addr== 0xff13ffff0 (where nothing is connected) // but then phys_page_find returns a nonzero and produces Unassigned mem read access of 1 byte to 0000000ff15ffff0 from xxxxx (note the "5" in the line above where "3" is expected) I wonder if this is only true for non-wired addresses, or whether phys_page_find can also find wrong pages for the addresses where something is connected? Or is my assumption is wrong and phys_page_find can return a page for not-connected addresses and the bug is actually in cpu_physical_memory_rw ? Is the qemu algorithm of working with the physical address space described somewhere? -- Regards, Artyom Tarasenko solaris/sparc under qemu blog: http://tyom.blogspot.com/
