1*4882a593Smuzhiyun1. Need to figure out why PCI writes to the IOC3 hang, and if it is okay
2*4882a593Smuzhiyunnot to write to the IOC3 ever.
3*4882a593Smuzhiyun2. Need to figure out RRB allocation in bridge_startup().
4*4882a593Smuzhiyun3. Need to figure out why address swaizzling is needed in inw/outw for
5*4882a593SmuzhiyunQlogic scsi controllers.
6*4882a593Smuzhiyun4. Need to integrate ip27-klconfig.c:find_lboard and
7*4882a593Smuzhiyunip27-init.c:find_lbaord_real. DONE
8*4882a593Smuzhiyun5. Is it okay to set calias space on all nodes as 0, instead of 8k as
9*4882a593Smuzhiyunin irix?
10*4882a593Smuzhiyun6. Investigate why things do not work without the setup_test() call
11*4882a593Smuzhiyunbeing invoked on all nodes in ip27-memory.c.
12*4882a593Smuzhiyun8. Too many do_page_faults invoked - investigate.
13*4882a593Smuzhiyun9. start_thread must turn off UX64 ... and define tlb_refill_debug.
14*4882a593Smuzhiyun10. Need a bad pmd table, bad pte table. __bad_pmd_table/__bad_pagetable
15*4882a593Smuzhiyundoes not agree with pgd_bad/pmd_bad.
16*4882a593Smuzhiyun11. All intrs (ip27_do_irq handlers) are targeted at cpu A on the node.
17*4882a593SmuzhiyunThis might need to change later. Only the timer intr is set up to be
18*4882a593Smuzhiyunreceived on both Cpu A and B. (ip27_do_irq()/bridge_startup())
19*4882a593Smuzhiyun13. Cache flushing (specially the SMP version) has to be investigated.
