1.1  scole $ NetBSD: TODO,v 1.1 2018/04/14 12:06:03 scole Exp $
1.1  scole
1.1  scole What works:
1.1  scole   The ski simulator (pkgsrc/emulators/ski) works on NetBSD, can run
1.1  scole   and step through in assembly.
1.1  scole
1.1  scole   Netbooting may work on some machines, basically you need to boot
1.1  scole   diskless with the loader.efi (from src/sys/arch/ia64/stand/ia64/)
1.1  scole   using dhcpd and put the kernel in a nfs accessible directory.  There
1.1  scole   is info here https://www.netbsd.org/docs/network/netboot/ and
1.1  scole   http://gnats.netbsd.org/49717 about how to setup.
1.1  scole
1.1  scole   Also, a successful report of booting off the CD is here
1.1  scole   http://mail-index.netbsd.org/port-ia64/2009/06/18/msg000102.html
1.1  scole
1.1  scole Tasks remaining, first couple seem most important:
1.1  scole
1.1  scole - context switching and forking appear unfinished,
1.1  scole   vm_machdep.c::cpu_lwp_fork() appears incomplete
1.1  scole - pmap module, imported from freebsd but still needs more work and
1.1  scole   testing
1.1  scole - IA64 Stack unwind code: Support remaining unwind descriptor
1.1  scole   types. (See arch/ia64/unwind/TODO). ddb() traces need to print line
1.1  scole   information also.  Seems like a lot of this could be re-used
1.1  scole   from freebsd
1.1  scole - redo _regset.h in netbsd style with __greg_t __gregset_t
1.1  scole - some commands in ski are not yet implemented, 2 important ones
1.1  scole   are still missing, "cstack" and "pm", which view the stack and
1.1  scole   source code lines respectively
1.1  scole - create a ski network driver
1.1  scole - create a ski disk driver
1.1  scole - implement ld.elf_so, MK_DYNAMICROOT
1.1  scole - fix memory detection, on real hardware doesn't find all memory
1.1  scole - implement interrupts (sacpi & pci), can be mostly from freebsd?
1.3  scole - MKGDB for ia64
1.1  scole - implement fp[gs]etsticky, [make|get|set|swap]context
1.1  scole - floating point, fenv functions were imported from freebsd, but haven't been tested
1.1  scole - implement core_machdep.c
1.1  scole - implement __cloneS ptrace.S sbrk.S shmat.S
1.1  scole - implement kvm_ia64.c
1.1  scole - implement pmc (performance monitoring counters) for ia64 pmc registers
1.3  scole - implement ia64 md code for cpuctl, intrctl as needed
1.1  scole - optional(?) mutex.h/lock_stubs.S, mutex_enter()/mutex_exit() __HAVE_MUTEX_STUBS
1.1  scole        mutex_spin_enter()/mutex_spin_exit() __HAVE_SPIN_MUTEX_STUBS
1.1  scole - rwlock.h rw_enter(),rw_exit(),rw_tryenter() __HAVE_RW_STUBS, implemented already?
1.1  scole - add efipart_dev to read gpt/ffs disks for bootloader
1.1  scole - fix printf of lx in bootloader/libsa ?
1.1  scole - sort out bootloader/loader.efi stuff, is freebsd one good enough or
1.1  scole   do we want commands more like netbsd i386 bootloader? e.g., add
1.1  scole   command to boot nfs from loader.efi instead of hack now
1.1  scole - ia64 implement __HAVE_FAST_SOFTINTS?
1.2  scole - want or need __HAVE_CPU_UAREA_ROUTINES, cpu_uarea_alloc,  cpu_uarea_free
1.1  scole - fix all "[Nn]ot yet" and "XXX" functions everywhere
1.1  scole - create/fix sys/arch/ia64/include/pci_machdep.h and implement actual functions,
1.1  scole   need to handle "multiple" pci busses like from http://www.openpa.net/systems/il/rp3400-bus.txt,
1.1  scole   add pchb, looks like one here
1.1  scole    http://mail-index.netbsd.org/port-ia64/2010/06/29/msg000116.html
1.1  scole   and/or could port from freebsd
1.1  scole - Kernel module pre-loading via the bootloader
1.1  scole - SMP
1.1  scole - write console and/or X framebuffer driver.  freebsd has vgapci
1.1  scole   device that may be portable
1.1  scole - add ia32 emulation, port from freebsd
1.1  scole - add rump stuff/MKRUMP
1.1  scole - create install EFI/cdrom/netbsd
1.3  scole - fix ski to run on other archs beside i386, or at least amd64
1.2  scole
1.2  scole Pie in the sky
1.2  scole - Xen and itanium!
1.2  scole - qemu and itanium
