-There is a `master-x86_64` [[GNU Mach
-branch|http://git.savannah.gnu.org/cgit/hurd/gnumach.git/log/?h=master-x86_64]].
-As of 2012-11-20, it only supports the [[microkernel/mach/gnumach/ports/Xen]] platform for now.
-
-**What is left for initial support (32-on-64) is**
-
- * add 64bit boot support from grub's multiboot
- * implement 32/64 RPC compatibility for RPCs served by kernel.
-
-See [[http://lists.gnu.org/archive/html/bug-hurd/2012-04/msg00000.html]]
-
**For pure 64bit support, we need to**
- * add 64bit definitions in binutils
- * add 64bit definitions in gcc
- * implement 64bit variants of code in glibc/sysdeps/mach/i386 and glibc/sysdeps/mach/hurd/i386
- * implement 64bit variants of code in libpthread/sysdeps/i386, libpthread/sysdeps/mach/i386, libpthread/sysdeps/mach/hurd/i386
- * fetch from Linux 64bit variant of code in ./pfinet/linux-src/arch/i386 and ./pfinet/linux-src/include/asm-i386
- * define the mig ABI
- * bootstrap a distrib, e.g. Debian hurd-amd64 (see [[https://jenkins.debian.net/view/rebootstrap/job/rebootstrap_hurd-amd64_gcc8/]] )

- <youpi> it'd be really good to have a 64bit kernel, no need to care about
- addressing space :)
- <braunr> yes a 64 bits kernel would be nice
- <braunr> i guess it wouldn't be too hard to have a special mach kernel for
- 64 bits processors, but 32 bits userland only
- <youpi> well, it means tinkering with mig

- <braunr> youpi: just so you know in case you try the master-x86_64 with
- grub
- <braunr> youpi: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=689509
- <youpi> ok, thx
- <braunr> the squeeze version is fine but i had to patch the wheezy/sid one
- <youpi> I actually hadn't hoped to boot into 64bit directly from grub
- <braunr> youpi: there is code in viengoos that could be reused
- <braunr> i've been thinking about it for a time now
- <youpi> ok
- <braunr> the two easiest ways are 1/ the viengoos one (a -m32 object file
- converted with objcopy as an embedded loader)
- <braunr> and 2/ establishing an identity mapping using 4x1 GB large pages
- and switching to long mode, then jumping to c code to complete the
- initialization
- <braunr> i think i'll go the second way with x15, so you'll have the two :)

+ * bootstrap a distribution. Debian is done. Alpine-Hurd is mostly
+ bootstrapped. Reach out to Sergey if you are interested in an
+ Alpine-Hurd distribution with bleeding-edge software. Reach out
+ to Guix, if you want to help them bootstrap a 64bit Hurd.

+**TODO**
-In context of [[mondriaan_memory_protection]].
+ * Fix swapping with rumpdisk
+ * Fix crash-dump-core server
- <xscript> BTW, it's not like I have an infinite amount of time for this,
- but having 64-bit support would be valuable for me, so I might contribute
- that back if it's not a too monumental task
- <xscript> I saw some discussions about 32bit apps on top of 64bit mach, but
- I'd like a full 64bit system
- <xscript> any clues?
- <xscript> I suppose the compiler support is all there already
- <xscript> is MIG (and mach) the only piece missing?
- <braunr> the problem is the interfaces themselves
- <braunr> type widths
- <braunr> as passed between userspace and kernel
+**Installing via the installer image**
+The installer works fine in qemu. Give it a shot! Let us know
+how it works in real hardware!

- <dharc> and what about 64 bit support, almost done?
- <youpi> kernel part is done
- <youpi> MIG 32/64 trnaslation missing
+**Installing a 64bit system**
-[[mig_portable_rpc_declarations]].
+In principle crosshurd should be working.
