[Qemu-devel] [PATCH] [RFC] Solaris user emulation

[-- Attachment #1: Type: text/plain, Size: 582 bytes --]

Hi,

I started to add support for (Open)Solaris user emulation. It compiles
but doesn't work yet, this is just a preview. The patch is largely
copy & paste from BSD user and there are no docs yet.

The current blocking problem is that I don't know how to make the
qemu-i386 executable a shared ELF object which Solaris wouldn't refuse
to execute (with native ld). Without that, qemu-i386 and the target
executable occupy same memory region, leading to a crash. Any hints
are welcome.

One problem is that Solaris headers are CDDL licensed and IIRC that
was not compatible with GPL.

Using the headers is compatible with the GPL, since it falls under the
source code usually delivered with the system exception (eg, it is
outside the full and complete sources).

Copying them into qemu would, however, be a problem because of the
patent clauses in CDDL and you'd clearly no longer be able to take
advantage of that exception.
