Description nwf 2009-09-12 20:40:04 UTC
emulators/qemu excludes sparc64 via ONLY_FOR_ARCH but there's relatively little that seems to need to change to fix that.


Relaxen and watchen das blinkenlights for libmath; this hack for i386 and x68_64 is unneded on sparc64.

dyngen-exec.h needs to be told that we define {u,}int64_t already

cpu-exec.c needed to include sys/ucontext.h on FreeBSD too, not just Linux

cpu-exec.c:cpu_signal_handler needed to be told in the right spot :
#elif defined(__FreeBSD__)
    ucontext_t *uc = puc;
    void *sigmask = &uc->sigmask;
    unsigned long pc = uc->uc_mcontext.mc_tpc;

How much of this should be worked around in ports vs. how much should go upstream I am not sure.  I'm also not sufficiently familiar with the workings of ports to propose a patch, sorry. :)

I agree with $Subject, but you'll have to help me there as I don't have
a sparc box to play with...  First, this should probably be done with a
git snapshot so that merging the fixes upstream will be easier, and also
there may be bugfixes done since 0.10.6 that might be useful to you.
The latest git snapshot I made a port update for is
- apply this to a copy of the current /usr/ports/emulators/qemu-devel
dir, remove files/patch-fbsd and files/patch-libmath* (we can take
care of applying these conditionally later), do a `make patch' and
back up the work/ dir that creates, then you are ready to apply the
remaining fixes you mentioned below work/ and anything else you find
necessary to get `make' to build a properly working port.  After that
you can do like `diff -urp work-backup work >sparc64.diff' to extract
your fixes and then send them to me.  Oh and if you patched something
later but `make' won't build again you need to `rm work/.build_done.*' .
More info is here:

 Thanx! :)

  FreeBSD ports repository

  Modified files:
    emulators/qemu-devel Makefile distinfo pkg-plist 
  - Update to 0.14.1 .
  - Change ALL_TARGETS knob to only affect the bsd-user targets that
    are still incomplete.  (they would be for emulating a single
    process instead of an entire OS; default off i.e. don't build
  - Fix ADD_AUDIO knob to also emulate hda sound hardware.
  - Change CONFLICTS to CONFLICTS_INSTALL in case people that already
    have emulators/qemu installed want to test this version from below
    the work/ dir.
  - Prepare Makefile for sparc64 host build in case someone wants to
    debug the runtime problems there. [1]  (Add sparc64 to ONLY_FOR_ARCHS
