[Qemu-devel] x86_64 vs. i386

["Philipp Gühring" <pg@futureware.at>]

Hi,

The current Linux distributions for x86_64 can run both 64Bit and 32Bit 
applications. But they have one major problem: 64Bit applications have to use 
64Bit libraries, and 32Bit applications have to use 32Bit libraries.

One huge problem for example is the non-existance of a 64Bit Flash-Player at 
the moment.

Those are the usual error message for 32 vs. 64 bit problems

/usr/lib/firefox/firefox-bin: error while loading shared libraries: 
libasound.so.2: wrong ELF class: ELFCLASS64

Inconsistency detected by ld.so: dl-close.c: 342: _dl_close: Assertion 
`tmap->l_ns == ns' failed!

Now I am wondering, whether it would be possible to integrate the processor 
emulator of qemu into the Linux kernel, so that applications can 
transparently use different-bitsized libraries by qemulating them on demand?

Best regards,
Philipp Gühring
