|
|
Hi,
I have a 32bit system with no physical access. I now need a 64 bit system to run both gpus. (vmalloc issue) - can I somehow bootstrap the running system (and kernel) into 64 bits? |

32 Bit chroot would be an option if you have a partition you can install some 64 bit utils.
Not sure that would even be of any use considering that your core issue relates to the fact that you are running a 32 bit with what ever it's used for.

EDIT And with no way of booting a live ISO I'd say you have no hope. |

Fixing the kernel is really easy - just check the first option that comes up in `make nconfig` and recompile.
Upgrading userspace to 64-bit is going to be a problem. You might be able to do a chroot install but swapping the main system for it will be difficult. The last time I changed ABIs I used btrfs subvolumes to swap out the "rootfs". |

Does the system support IPMI and do you have access to it that way?
Do you need an upgrade or can it be a wipe/reinstall? |
