**What is left for initial support (32-on-64) is**
* Fixing bugs :)
**For pure 64bit support, we need to**
* Fix bugs :)
* bootstrap a distrib
**Installing a 64bit chroot**
Make sure to have `debootstrap >= 1.0.128+nmu2+hurd.1`
sudo debootstrap --foreign --verbose --arch hurd-amd64 --keyring=/usr/share/keyrings/debian-keyring.gpg sid chroot-hurd-amd64 https://people.debian.org/~sthibault/tmp/hurd-amd64
Then boot it, it will drop you into a shell. You need to make / writable:
fsysopts / --writable
and then run the second stage of the deboostrap:
tail -f /debootstrap/debootstrap.log &
/debootstrap/debootstrap --second-stage
(the warnings `chown: invalid user: 'root'` are ok at that stage)
set a root password:
password
and reboot:
reboot-hurd
**Installing a 64bit system**
In principle crosshurd should be working, one however needs to add this source:
deb http://people.debian.org/~sthibault/tmp/hurd-amd64 unstable
into /etc/crosshurd/sources.list/gnu
# IRC, freenode, #hurd, 2011-10-16
<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
[[mig_portable_rpc_declarations]].
# IRC, freenode, #hurd, 2012-10-03
<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 :)
## IRC, freenode, #hurd, 2013-07-02
In context of [[mondriaan_memory_protection]].
<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
## IRC, OFTC, #debian-hurd, 2013-10-05
<dharc> and what about 64 bit support, almost done?
<youpi> kernel part is done
<youpi> MIG 32/64 trnaslation missing
[[mig_portable_rpc_declarations]].
