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?
Thanks,
Rex Luo
