Hi, The file system I have has some files in 64-bit ELF format and some in 32-bit. Is it possible to run such a file system with a 64-bit Linux kernel compiled as UML with ARCH=um ? Normally, if I start up the UML, I get an error "request_module: runaway loop modprobe binfmt-464c". Is there any way to do this? Thanks. |

No, x86_64 UML does not have x86_32 emulation. -- Thanks, //richard |

Is there any particular reason as to why UML doesn't have this while Linux on hardware does? Thanks.

http://lkml.indiana.edu/hypermail/linux/kernel/1002.2/01983.html I see this thread discussing a similar issue where the main question is unanswered. Is it just a case of the Kconfig option not being there? Is there any other way by which I can run 32-bit binaries on a 64 bit UML kernel? Thanks.

Is it just a case of the Kconfig option not being there? No, minimal support for 32-bit on 64-bit kernel had been available briefly around ~2.6.9 (a long time ago) Re-adding this feature would take some effort. > Is > there any other way by which I can run 32-bit binaries on a 64 bit UML > kernel?
