- Update emulators/qemu-devel to 1.4.0 with preliminary bsd-user patches.
Thanx to: sson, cognet, and others for much improved bsd-user support -
it now runs at least quite a few mips64 and single-threaded
arm binaries, see:
https://wiki.freebsd.org/QemuUserModeHowTo
http://lists.nongnu.org/archive/html/qemu-devel/2012-07/msg01626.html
- Rename CLANG workaround knob to CLANG_HACK to avoid it being
inadvertently triggered by WITH_CLANG in make.conf etc.
- Change USE_BZIP2=yes to EXTRACT_SUFX=.tar.bz2 because the
1.1.1 distfile is in fact compressed with gzip not bzip2 despite
the extension.
- Add preliminary arm-bsd-user support, this still will only run
very simple executables like a static echo (the same as the rest
of the bsd-user targets) due to lots of syscall handling still
missing. Help welcome there! :)
This work was started by bapt and cognet, I fixed syscall arg
passing (only the first four are passed in registers, the rest
on the stack) as well as errno and carry handling at syscall
return among other things and cleaned up cognet's version a bit.
(The OpenBSD case is untested and probably wrong.) [1]
Some notes in this post:
http://lists.freebsd.org/pipermail/freebsd-emulation/2012-July/009901.html
Submitted by: cognet [1] (initial version of the patch)
emulators/qemu-devel. [1]
- Convert both qemu ports to OPTIONng.
Submitted by: luigi [1] (original version of the patch)
Optained from: qemu-devel mailinglist [1] (improved version of the patch)
and a patch for promiscuous multicast for the emulated e1000 nic,
both to support using qemu with the (also to be updated)
emulators/gns3 port.
- Change DIST_SUBDIR to qemu/${PORTVERSION} because PATCHFILES names
are not versioned.

1. Fix packet delays. [1]
2. Truncate oversize packets according to host interface's MTU
to avoid e.g. Linux guests panic'ing.
Note: This is only necessary as a stopgap measure for cases like
host inferfaces using TSO (it still causes retransmissions),
the better workaround is to disable the feature on the host
interface while using qemu's pcap code.
- Add note about pcap to pkg-message.s
- Bump PORTREVISIONs.

release announcement is here:
http://lists.gnu.org/archive/html/qemu-devel/2009-12/msg02151.html
Quoting from pkg-message:
- kqemu is no longer supported in qemu upstream after the 0.11 branch
was created, which means also not in this version. (Linux has moved
on to kvm now for qemu(-like) virtualization needs, so if you want qemu
to go faster and don't want to switch to virtualbox or stick to the older
emulators/qemu port which is at 0.11.1 atm and as such still supports
kqemu you should help getting the FreeBSD kvm port updated and
completed:
http://wiki.freebsd.org/FabioChecconi/PortingLinuxKVMToFreeBSD
)
port that now also works for the 32 bit "qemu" executable on amd64
(if you build with the KQEMU knob on, you have to deinstall the old
kqemu-kmod first if it is installed)
- Add an ALL_TARGETS knob that, if turned off, omits the remaining dyngen
targets, eliminating the need for gcc 3.4 (everything but ppc and sh4
has been converted to tcg in this snapshot)
- Add tcg fixes for amd64 guests on i386 hosts (two of three have been
committed to qemu svn in the meantime) [1]
- Update the pkg-message about kqemu on amd64, and add a note about using
nfs with slirp, the latter [2]

- PowerPC bugfixes:
- must clear carry bit when doing addic with a zero immediate value
- fix missing RETURN in micro-operation that would lead to random failures
and crashes
- add USE_PRECISE_EMULATION compilation-time option to choose between
getting exact floating point results and fast but less accurate computation.
- PowerPC improvments:
- add missing 64 bits rotate instructions
- safely define TARGET_PPCSPE when 64 bits registers are used
a separate target will be needed to use it in 32 bits mode on 32 bits hosts.
- MIPS: Fix enough FPU/R2 support to get 24Kf going.
- Add missing PowerPC 64 instructions
PowerPC 64 fixes.
- Upgrade Sparc FPU version (based on patch by Aurelien Jarno)
- One more bit of mips CPU configuration, and support for early 4KEc
which implemented only MIPS32R1. Thanks to Stefan Weil to insist he's
right on that. :-)
- Sparc32/64 CPU selection
- Fix segfault with -nographic, by Enache Adrian.
- New model for PowerPC CPU hardware interrupt events:
move all PowerPC specific code into target-ppc/helper.c to avoid polluting
the common code in cpu-exec.c. This makes implementation of new features
(ie embedded PowerPC timers, critical interrupts, ...) easier.
This also avoid hardcoding the IRQ callback in the OpenPIC controller,
making it more easily reusable and allowing cascading.
- Fix / update PowerPC BookE definitions.
- PPC: Fix rfi instruction: do not depend on current execution mode
but on the execution mode that will be effective after the return.
Add rfci, rfdi and rfmci for BookE PowerPC.
Extend mfdcr / mtdcr and implement mfdrcx / mtdcrx.
- Sanitize mips exception handling.
- Better fix for OpenPIC: should not depend on PowerPC.
- As embedded PowerPC TLB model is very different from PowerPC 6xx ones,
define ppc_tlb_t as an union of the two.
- Merge PowerPC 405 MMU model.
- Embedded PowerPC timers support.
- Support for PowerPC BookE exception model.
No need to requeue timer exceptions.
Fix nip saving for 64 bits PowerPC.

- Fix usb hid and mass-storage protocol revision, by Juergen Keil.
- Update for binfmt_misc handler, by Stefan Weil.

by Juergen Keil.
- MIPS32R2 needs RDPGPR/WRPGPR instructions even when no shadow registers
are implemented.
- i386 return APIC ID with cpuid, by Bernhard Kauer.
- Infrastructure to support more than 2 MMU modes.
Add example for Alpha and PowerPC hypervisor mode.
- And some more bugfixes
Approved by: miwi (mentor, implicit)
- ARM reabbot support (orginal patch by Aurelien Jarno).
- SMP half-idle fix.
- Watchpoint support (previous commit got eaten by Savannah server crash).
- ARM register index+writeback fix (Lauro Ramos Venancio).
- PPC: Make it safe to use 64 bits GPR and/or 64 bits host registers.
For "symetry", add 64 bits versions of all modified functions.
As a side effect, add a lot of code provision for PowerPC 64 support.
Move overflow and carry checks in common routines for simple cases.
Add isel and popcntb instructions from PowerPC 2.03 specification.
Remove remaining micro-operations helpers prototypes from op.c.
Fix XER_BC field to be 7 bits long.
Add power management support for PowerPC 603 & 604.
Fix compilation warnings.
Add PowerPC 64 target for tests.
As no PowerPC 64 CPU is implemented, this target can just be used to
check that there is no difference between PowerPC 32 & PowerPC 64 used
in 32 bits mode.
