Hello ,in kvm_set_phys_mem,I am confused about the following codes:
delta = TARGET_PAGE_ALIGN(size) - size;
if (delta > size) {
return;
}
start_addr += delta;
size -= delta;
size &= TARGET_PAGE_MASK;why start_addr need to add delta,and why size sub delta,in my own opinion,if size +=delta ,I can understand,but i do not know why sub??thanks in advance!!
