Dear all, I study FreeBSD vm managememnt recently, however, I am a little confused with vm_page's page color. when you call vm_add_new_page() in vm_startup(), you will set each map entry's page color according to its physical addr. m->pc = (pa >> PAGE_SHIFT)&PQ_L2_MASK; However, I found that almost each map entry's page color is zero, that means PQ_L2_SIZE is 1, and disable page coloring option. Maybe I can do some modification to dump PQ_L2_SIZE's value, but I think my guess is right. Can someone please tell me the principle of page coloring, and why it's disabled now?
