[Qemu-devel] [Bug 917645] [NEW] [Feature request] ia64-softmmu wanted

[Jakub Jermar]

Public bug reported:

Qemu is missing support for full system emulation of the Itanium
architecture, which is one of the main non-x86 server architectures
today (despite the alleged decline in popularity). It would be really
nice if someone had interest in adding full ia64 support to Qemu. Many
OS projects could then use Qemu as the universal machine emulator for
development and testing.

Note that there is an open source Ski simulator which can emulate an
ia64 CPU, memory and a couple of Ski-specific devices, but the project
seems inactive and the simulated machine is too simplified (no real
devices, no real firmware). Moreover, it'd be better to have one tool
such as Qemu for all architectures of interest rather than one per each
architecture.

It may be actually easier to start with recreating the Ski machine
inside QEMU. The result will be a faster Ski in a maintained codebase.
Definitely not a bad start.

[Bug 917645] Re: [Feature request] ia64-softmmu wanted

[Peter Maydell]

The QEMU project doesn't implement new target architectures or board
models on demand based on wishlist requests; they're a lot of work to
do. Instead we simply code-review and incorporate board models and
architectures as and when people decide to write them and submit the
patches. So there's really no point in having a 'wishlist' bug in the
bug tracker saying "support for board X would be nice", because it will
never happen, unless by the coincidence that somebody happened to
implement and submit it to us anyway.

So I'm going to close this bug as "Won't Fix"; if anybody happens to
want to work with upstream on implementing this board model they are
welcome to do so -- the mechanism for that is to email qemu-devel (with
plans, requests for advice or patches).
