[Qemu-devel] Question about cpu_get_phys_page_debug()

[Wen Congyang]

In the function cpu_get_phys_page_debug()(In the file target-i386/helper.c):
I find the following codes:
====================
    page_offset = (addr & TARGET_PAGE_MASK) & (page_size - 1);
    paddr = (pte & TARGET_PAGE_MASK) + page_offset;
====================

The page_offset is always 4K aligned.
I think the offset should be the offset in the page, so it should
not be aligned.

Who can tell me the reason?

Thanks
