+
+    <body>
+      <p>The ports-mgmt/poudriere-devel port is aware of how to build
+	ports via an emulator.  Configuration of the miscellaneous
+	binary image activator is required prior to a poudriere-devel
+	run.</p>
+
+      <p>ARMV6, MIPS32 and MIPS64 packages can be produced via full
+      emulation.  There are several packages that block a full run of
+      builds.  They can be viewed on the Status of ports building
+      link.</p>
+
+      <p>On current or latest stable/10:</p>
+
+      <p>Clone the <url href="https://github.com/seanbruno/qemu-bsd-user">github</url>
+	repository of qemu, and switch to
+	the bsd-user branch.  Then run:</p>
+
+      <p><tt>./configure --static \<br/>
+	  --target-list="arm-bsd-user i386-bsd-user \<br/>
+	  mips-bsd-user mips64-bsd-user mips64el-bsd-user \<br/>
+	  mipsel-bsd-user ppc-bsd-user ppc64-bsd-user sparc-bsd-user \<br/>
+	  sparc64-bsd-user x86_64-bsd-user"</tt></p>
+
+      <p><tt>gmake; gmake install</tt></p>
+
+      <p>Then setup the binmiscctl tools to do some evil hackery to
+	redirect execution of armv6 binaries to qemu:</p>
+
+      <p><tt>binmiscctl add armv6 --interpreter \
+	  "/usr/local/bin/qemu-arm" --magic \
+	  "\x7f\x45\x4c\x46\x01\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02 \<br/>
+	  \x00\x28\x00" --mask "\xff\xff\xff\xff\xff\xff\xff\x00\xff\xff\xff\xff \<br/>
+	   \xff\xff\xff\xff\xfe\xff\xff\xff" --size 20 --set-enabled</tt></p>
+
+      <p>Install poudriere-devel from ports.  It knows how to setup
+	things.</p>
+
+      <p>Build poudriere jail to do all the magic:</p>
+
+      <p><tt>poudriere jail -c -j 11armv632 -m svn -a armv6 \<br/>
+	  -v head</tt></p>
+
+      <p>You can now run poudriere against that jail to build all the
+	ports:</p>
+
+      <p><tt>poudriere bulk -j 11armv632 -a</tt></p>
+
+      <p>Nullfs mount your ports tree into the jail:</p>
+
+      <p><tt>mkdir /usr/local/poudriere/jails/11armv632/usr/ports<br/>
+	  mount -t nullfs /usr/ports /usr/local/poudriere/jails/11armv632/usr/ports</tt></p>
+      <p>To chroot into the jail:</p>
+
+      <p><tt>mount -t devfs devfs /usr/local/poudriere/jails/11armv632/dev<br/>
+	  chroot /usr/local/poudriere/jails/11armv632/</tt></p>

+           PPC on AMD64 emulation.  WIP as there appears to be some serious issues running the bsd-user binary on big endian hardware.  Justin Hibbits working on this.

+      <task>
+           SPARC64 on AMD64 emulation is non-functional and instantly segfaults.  Looking for someone to poke at the bits here.

+      <task>
+           External Tool Chain, XDEV support.  Partial support for using an AMD64 tool chain that can output other architecture (use AMD64 toolchain to build MIPS64 packages).  Currently tracking a linking issue with ports-mgmt/pkg.  Thanks to Warner Losh, Baptiste Daroussin, Dimitry Andric for poking at bits in here to make the XDEV target useful.

+      <task>
+           Signal Handling, MIPS/ARMV6 target still displays a failure that manifests itself when building devel/p5-Sys-SigAction
+      </task>
+      <task>
+           Massive documentation update needed.  These modifications actually allow you to chroot into a MIPS or ARMv6 environment and use native tool chains and libraries to prototype your software for a target platform.
