3What works:
4  The ski simulator (pkgsrc/emulators/ski) works on NetBSD, can run
5  and step through in assembly.
6
7  Netbooting may work on some machines, basically you need to boot
8  diskless with the loader.efi (from src/sys/arch/ia64/stand/ia64/)
9  using dhcpd and put the kernel in a nfs accessible directory.  There
10  is info here https://www.netbsd.org/docs/network/netboot/ and
11  http://gnats.netbsd.org/49717 about how to setup.
12
13  Also, a successful report of booting off the CD is here
14  http://mail-index.netbsd.org/port-ia64/2009/06/18/msg000102.html

16Tasks remaining, first couple seem most important:
17
18- context switching and forking appear unfinished,
19  vm_machdep.c::cpu_lwp_fork() appears incomplete
20- pmap module, imported from freebsd but still needs more work and
21  testing
22- IA64 Stack unwind code: Support remaining unwind descriptor
23  types. (See arch/ia64/unwind/TODO). ddb() traces need to print line
24  information also.  Seems like a lot of this could be re-used
25  from freebsd
26- redo _regset.h in netbsd style with __greg_t __gregset_t
27- some commands in ski are not yet implemented, 2 important ones
28  are still missing, "cstack" and "pm", which view the stack and
29  source code lines respectively 
30- create a ski network driver
31- create a ski disk driver
32- implement ld.elf_so, MK_DYNAMICROOT
33- fix memory detection, on real hardware doesn't find all memory
34- implement interrupts (sacpi & pci), can be mostly from freebsd?
35- MKGDB for ia64
36- implement fp[gs]etsticky, [make|get|set|swap]context
37- floating point, fenv functions were imported from freebsd, but haven't been tested
38- implement core_machdep.c
39- implement __cloneS ptrace.S sbrk.S shmat.S
40- implement kvm_ia64.c
41- implement pmc (performance monitoring counters) for ia64 pmc registers
42- implement ia64 md code for cpuctl, intrctl as needed
43- optional(?) mutex.h/lock_stubs.S, mutex_enter()/mutex_exit() __HAVE_MUTEX_STUBS
44       mutex_spin_enter()/mutex_spin_exit() __HAVE_SPIN_MUTEX_STUBS
45- rwlock.h rw_enter(),rw_exit(),rw_tryenter() __HAVE_RW_STUBS, implemented already?
46- add efipart_dev to read gpt/ffs disks for bootloader
47- fix printf of lx in bootloader/libsa ?
48- sort out bootloader/loader.efi stuff, is freebsd one good enough or
49  do we want commands more like netbsd i386 bootloader? e.g., add
50  command to boot nfs from loader.efi instead of hack now
51- ia64 implement __HAVE_FAST_SOFTINTS?
52- want or need __HAVE_CPU_UAREA_ROUTINES, cpu_uarea_alloc,  cpu_uarea_free
53- fix all "[Nn]ot yet" and "XXX" functions everywhere
54- create/fix sys/arch/ia64/include/pci_machdep.h and implement actual functions,
55  need to handle "multiple" pci busses like from http://www.openpa.net/systems/il/rp3400-bus.txt,
56  add pchb, looks like one here
57   http://mail-index.netbsd.org/port-ia64/2010/06/29/msg000116.html
58  and/or could port from freebsd
59- Kernel module pre-loading via the bootloader
60- SMP
61- write console and/or X framebuffer driver.  freebsd has vgapci
62  device that may be portable
63- add ia32 emulation, port from freebsd
64- add rump stuff/MKRUMP
65- create install EFI/cdrom/netbsd
66- fix ski to run on other archs beside i386, or at least amd64
67
68Pie in the sky
69- Xen and itanium!
70- qemu and itanium
