The pmap.c code looks somewhat different in 3.4-STABLE, and it wasn't
obvious to me what the complete patch for 3.4-STABLE would be.
However, I was trying to get an IBM Netfinity 5600 server to run SMP,
and this box has both the two IOAPICs on page boundaries. Thus I was
hoping I could get away with only fixing the typo you found:
*** pmap.c.orig Sat Apr 1 23:58:17 2000
--- pmap.c Fri Apr 21 12:30:11 2000
***************
*** 434,440 ****
for (j = 0; j < 16; j++) {
/* same page frame as a previous IO apic? */
if (((vm_offset_t)SMP_prvpt[j + 16] & PG_FRAME) ==
! (io_apic_address[0] & PG_FRAME)) {
ioapic[i] = (ioapic_t *)&SMP_ioapic[j * PAGE_SIZE];
break;
}
--- 434,440 ----
for (j = 0; j < 16; j++) {
/* same page frame as a previous IO apic? */
if (((vm_offset_t)SMP_prvpt[j + 16] & PG_FRAME) ==
! (io_apic_address[i] & PG_FRAME)) {
ioapic[i] = (ioapic_t *)&SMP_ioapic[j * PAGE_SIZE];
break;
}
and this does indeed seem to be the case. I'm now happily running SMP
on this box.
