In our design, requests that cross page are split into two non-cross page requests in
vaddr_write_cross_page
, which are handled separately invaddr_trans_and_check_exception
.However, in previous design,
vaddr_trans_and_check_exception
would pass a page-aligned vaddr (vaddr & ~PAGE_MASK
) intoisa_mmu_translate
, which would result in the lower 12 bits of exception address (page offset) written to *tval going to all zeros. This will result in an error against rtl if an exception occurs. This commit fixes it.
