TODO revision 1.5       1 $ NetBSD: TODO,v 1.1 2018/04/14 12:06:03 scole Exp $

      3 What 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
     15 
     16 Tasks remaining, first couple seem most important:
     17 
     18 - pmap.c is getting compilation warnings (for gcc6 & gcc7) like
     19   /var/tmp//cckQKcKn.s:7614: Warning: Use of 'st8' may violate RAW dependency 'RR#' (data)
     20   ...
     21   how to change compile flags for specific kernel file like "CFLAGS.pmap.c+= -O0" ?
     22 - context switching and forking appear unfinished,
     23   vm_machdep.c::cpu_lwp_fork() appears incomplete
     24 - pmap module, imported from freebsd but still needs more work and
     25   testing
     26 - IA64 Stack unwind code: Support remaining unwind descriptor
     27   types. (See arch/ia64/unwind/TODO). ddb() traces need to print line
     28   information also.  Seems like a lot of this could be re-used
     29   from freebsd
     30 - redo _regset.h in netbsd style with __greg_t __gregset_t
     31 - some commands in ski are not yet implemented, 2 important ones
     32   are still missing, "cstack" and "pm", which view the stack and
     33   source code lines respectively 
     34 - create a ski network driver
     35 - create a ski disk driver
     36 - implement ld.elf_so, MK_DYNAMICROOT
     37 - fix memory detection, on real hardware doesn't find all memory
     38 - implement interrupts (sacpi & pci), can be mostly from freebsd?
     39 - MKGDB for ia64
     40 - implement fp[gs]etsticky, [make|get|set|swap]context
     41 - floating point, fenv functions were imported from freebsd, but haven't been tested
     42 - implement core_machdep.c
     43 - implement __cloneS ptrace.S sbrk.S shmat.S
     44 - implement kvm_ia64.c
     45 - implement pmc (performance monitoring counters) for ia64 pmc registers
     46 - implement ia64 md code for cpuctl, intrctl as needed
     47 - optional(?) mutex.h/lock_stubs.S, mutex_enter()/mutex_exit() __HAVE_MUTEX_STUBS
     48        mutex_spin_enter()/mutex_spin_exit() __HAVE_SPIN_MUTEX_STUBS
     49 - rwlock.h rw_enter(),rw_exit(),rw_tryenter() __HAVE_RW_STUBS, implemented already?
     50 - add efipart_dev to read gpt/ffs disks for bootloader
     51 - fix printf of lx in bootloader/libsa ?
     52 - sort out bootloader/loader.efi stuff, is freebsd one good enough or
     53   do we want commands more like netbsd i386 bootloader? e.g., add
     54   command to boot nfs from loader.efi instead of hack now
     55 - ia64 implement __HAVE_FAST_SOFTINTS?
     56 - want or need __HAVE_CPU_UAREA_ROUTINES, cpu_uarea_alloc,  cpu_uarea_free
     57 - fix all "[Nn]ot yet" and "XXX" functions everywhere
     58 - create/fix sys/arch/ia64/include/pci_machdep.h and implement actual functions,
     59   need to handle "multiple" pci busses like from http://www.openpa.net/systems/il/rp3400-bus.txt,
     60   add pchb, looks like one here
     61    http://mail-index.netbsd.org/port-ia64/2010/06/29/msg000116.html
     62   and/or could port from freebsd
     63 - Kernel module pre-loading via the bootloader
     64 - SMP
     65 - write console and/or X framebuffer driver.  freebsd has vgapci
     66   device that may be portable
     67 - add ia32 emulation, port from freebsd
     68 - create install EFI/cdrom/netbsd
     69 - fix ski to run on other archs beside i386, or at least amd64
     70 
     71 Pie in the sky
     72 - Xen and itanium!
     73 - qemu and itanium
